Looking at the fences, the gate, the wickets of various cottages, a man who has no idea about blacksmith tools, work in the forge, asks: Where does the money come from? A man who disassembled in the blacksmith craft will answer him that such things (metal furniture decorations, swing, shops) are made by means of fixtures for cold forging.

The cost of cold forging is not too big. It is due to low costs for equipping, high processing efficiency. Blacksmith, which is engaged in this type of work, can quickly start getting good profits. Probably, some owners of cottages themselves make all fences and gates, because the cold forging is possible to carry out in the garage room or a barn, without having any special skills.

The main thing that you will need is homemade equipment for cold forging. If you wish to make various metal items, you will need five to seven types of equipment. With your own hands of cold forging machines, it is possible to make three - five pieces. Before starting making, you need to study the basics of work in the forge.

Stamping, forging, bending

From stamping, a cold forging is excellent because the material under the action of the tool almost does not flow. Look at a jar of beer or, for example, a kettle from aluminum / tin. Their extrusion is carried out for 1 punching device.

From the hot forging, cold is different because the item before starting processing does not heal. The workpiece as it would be stuck, hitting it many times. Metal structure varies significantly. The strength of the surface rises, and the middle becomes more viscous. Handicraft masters highly appreciate the bandages of wheels of wagons, parts of rails.

Metal is stuck through conventional hammer. Make it personally easier than the homemade machine for cold forging. However, such a forging is still different from the label. With its execution, the metal structure does not change much.

Currently exist different kinds Cold forged machines. Electrical drive is rarely used, because the increase in the efficiency of the efficiency often does not justify the difficulty of creating, spending on electricity. For cold forging, the machines are divided into:

• twisters - form flat spirals and other curls with a non-aged middle;
• torsion - make it possible to create a screw twisting of the rod and parts from volumetric spirals (filaments);
• stamping-inertial - with their help splashing the shaped tips, stamping of decorative clamps to combine patterned parts, extrusion of embossed elements on long products;
• bending - processing is carried out by pressing, pulling or combining these methods. In the first case, waves, zigzags, in the second - rings, curls are made.

In a variety of books, especially English, all homemade machines for cold forging with their own hands, which form products by spinning / curl are often called twisters. Initially, the twister was used to hide the springs. However, it is more correct to believe that the twister is a naval device, and the torsion machine is twisted.

Blanches

In a cold forging machine, with their own hands, the device is called a device intended to obtain zigzag elements. Replacing the roller / wedge, perhaps in a specific range to change the zigzag angle.

Bluck for pipes, rods up to sixteen millimeters is cheap. It is difficult to make it in domestic conditions, because you need point processing. Try an ordinary electric drill to make a hole in wrench. But the load in the abutment is much larger. In view of this, the gnutik is easier to purchase. It can be used for forging with her own hands and for the production of weld parts metal structures, folding small pipes.

Twisters

Since ancient times, the Master of the Blacksmithwork made curls on the canopy pattern by means of a horned lever capture. This method is inffective, but it makes it possible to create various bending mandrels from an ordinary metal strip without much difficulty and high time. The stubborn lever horn does not allow the template to move under pressure from the part. The rogue of the circuit must be sliding with fixing. Processing will flow more slowly, however with greater accuracy.

Another homemade fitting for shaped bending is a strong board with pins support. They can serve ordinary bolts. Processing is possible strip up to six millimeters. It all depends on your physical strength. Flex a striped "on the eyes". The process is quite slow, but it is possible to create a variety of patterns.

Snails

One of the types of twister (forging machine) is a snail. It is very common among people who are engaged in artistic forging. Snail has a simple design, available to create at home. In addition, it is convenient in operation and multifunctional. For the forging, the snail machine is suitable perfect. It represents a bending lever, which is slightly improved and mechanized. This metal forged metal forging equipment is divided into 2 species.

With Lemeh

The scheme of operation of this device for cold forging is as follows:

1. Snail turns.
2. The billet is fixed on the device.
3. Through the spring, the clamp of the roller is carried out to the part.
4. The snail rotation is rotated clockwise (levers are used).
5. Fixation is cleaned, the snail rises, the finished curl of the device gets from the device.

The advantages of this twister are:

• It is possible to process parts without special equipment. It is determined by the fact that the vertical load on the floor of the room is quite small.
• Support is easy enough, you can cook it from ordinary metal profiles.
• It is possible to work alone. Turn the gate with one hand, the second press the strip to Lemeh.
• It is possible to do spirals with five turns.

Lever

Similar manual machines for cold forging have a design similar to a pipe bender. They are less productive than devices with a gate. Load is quite large. In view of this, a strong base of special steel is required. Turning the lever to the jam, you need to move the clips of the clips. You can create up to four curls on the snail. Such manual Machine For cold forging with their own hands, has the following features:

• All elements, with the exception of the climber, can be made of ordinary steel.
• A standard roller bearing can serve as a clove of the clove.
• The base of the machine is capable of listening to more than a thousand working cycles.
• Flexible it is possible to carry out both the template and for spacecraft.
• It is possible to quickly change the shape of the manufactured product, to make reverse bends.
• The end of the workpiece is possible to fix it, putting it in the template recess. English is carried out by boobing either fold.

Torsion

This tool for cold forging makes it possible to increase the efficiency and increase the quality of products produced. The workforce is quite large, therefore it is necessary to base the high strength. A trapped 2-way frame from a hundred millimeters or a couple of connected channels is suitable. On the supporting surface, the base is required to be secured safely by the paw attached to it.

Detail (rod in the form of a square) is fixed by cartridges mandrel with sockets. Due to the fact that the rod during a twist decreases in length, the cartridges in the spindle element and the back of the grandmother must be well fastened with screw clips. Rear grandmother Must be sliding.

If the device is necessary for the manufacture, for example, a small fence, then you can make a machine for a cold forging with your own scrap, sweater.

Electric drive

Work on a torsional machine with non-electrical drive tedious. Good quality It is almost impossible to achieve. This is due to the fact that it is hard to achieve a uniform moment of rotation. In view of this, it is better to use an electric drive that must be installed in the tool for forging. The drive can be made from the subwoofers (semi-axis of the leading bridge of the car with rear-wheel drive, gear differential pair). The engine is 1.5-3 kW, 900 revolutions per minute. With other options, you can see, looking at the internet relevant videos.

Wave and Zigzag

How to make a cold forging machine, through which it is possible to create wave and zigzag elements? To do this, you will need rollers made of instrumental / chromonichel steel. The arc is the limiters that give the opportunity to create an accurate wave profile.

If you set a special gate on the snail, you can create waves. The handles apply the same. They screw in the thread slots on the barny head. The main roller is recommended to be located separately, attached to the base with the head bolts.

Forged products need to be combined into one. It is easiest to weld and then harden the seams with a grinder with a cleaner circle. It has a greater thickness than cut off, copes with bend efforts. Much better looks like parts that are connected by shaped clamps. Stamping is carried out of a strip from one and a half years. The hollow blank is made in the form of the letter "P". Her wings bend from the back by the hammer. Special enamels are used for staining, paints for metal products. Enamel with pigment are more expensive, but they are not prone to peeling, burning, wear and thermodood.

Loads that carry a press for cold forging, especially drums, quite high. This requires accurately process the blanks. In view of this, it is better not to try using the drawing of the machine for a cold forging, make a similar device. You can only make a manual rolling mill. However, steel rolls, shafts and bearing sleeves will still need to buy.

If you seriously intend to go for a blacksmithing case, try making twisters or torsion device. The machine for a cold forging drawings are quite simple, to figure them out in power, even a person who is very remotely familiar with forging work. Drawings of machines can be found on the Internet or ask familiar who are engaged in a blacksmith. Of course, the Profession "Kuznets" is less popular today than the same "conductor", but this does not mean that no one is engaged in forging.

Cold forging is impossible without special blacksmithing equipment. Let's look at the types of devices and figures that can be obtained with their help. We have prepared for you drawings and thematic videos. We will also consider the sequence of manufacturing the machine for cold forging with their own hands.

If you are just going to organize a cold forging workshop and want to avoid big expenses, then independent manufacture machines and devices will help create your own little business without excessive costs.

Main fixtures and machines

Cold forged machines are designed mainly for a flexible arc or an angle, as well as for twisting. They can be manual or with an electrically driven.

The main types of machines and fixtures for cold forging:

• Gnutik
• Twister
• Snail
• the globe
• Wave
• Flashlight

Device "Gnutic"

Purchased or made independently "Gnutik" is a universal device that allows you to get an arc or an angle of a rod. It is a base with a slider, which is focused with an angle (90 ° or other, as needed) and two cylindrical fixed stops. By moving the slider and the corner stop, the rod bends at an angle. To obtain an arc, a third cylinder is provided, rotating on the side opposite to the corner.

The device can be performed on a horizontal or vertical platform.

Axonometry of the GNUTIC devices - vertical location

To squeeze the dimensions, bring the bottom line of the bottom of this "Gnutka".

Planck Nizhnya

This device is universal. With the help of the nozzles on it, you can not only bend, but also cut, and piercing holes. But this will already be the next step.

So the homemade "Gnutic" looks like:

Device "Twister"

Twister is a tool for twisting rods, mostly square section, along the longitudinal axis. This simple fixture can be manual and with an electric drive. Principle of operation: Both ends of the rod are fixed, then one fastener begins to rotate, twisting the metal to the necessary form.

Exterior of the purchase of manual "twister"

Check out the photo of the homemade "twister" with an electric drive collected using the used electrical equipment in use:

For the manufacture of "flashlights" and "cones" there is a special machine, but for a start, you can also use "twister", as shown in the video (English-language, but everything is extremely clear).

Video: How to make a blank under the "flashlight" on the "Twister"

Device "Snail"

The "Snail" tool is designed to obtain curls (or spirals) and "currencies" (S-shaped parts). There are various designs.

One of the design options: 1 - LEMEkh Snails; 2 - the base of the machine; 3 - clamping roller; 4 - lever to control the clamping roller; 5 - fastening the base; 6 - finger for lemheov fixing; 7 - grooves for a native roller; 8 - axis control lever; 9 - spring for pressed roller; 10 - retainer for the workpiece; 11 - Lemche Lemeh Snail; 12 - the main axis; 13 - Levers

As a result, such a device should be obtained:

Another light design to bend rolled by a cross section to 12 mm:

1 - Snail segment; 2 - eccentric; 3 - handle; 4 - base; 5 - guide polishes; 6 - axis; 7 - slider; 8 - Axis Nut; 9 - axis fastening roller; 10 - roller; 11 - drive ax; 12 - guide eccentric; 13 - central snail segment; 14 - bars of eccentric; 15 - the main leg; 16 - connecting stall segments pin; 17 - correction screw; 18 - Snail segments coupling ear

Often, the device "snail" is done on the support, especially if you need to bend thick rental.

Several useful video materials homemade machines "Snails."

Work machine

We will talk more about such structures below.

Device "Globus"

Such a device looks like school transport and is intended for the manufacture of arcs with a large bending radius from the strip, square, a circle or hexagon. At first, one end of the workpiece is fixed by the bend, then it bends along the entire length of the template. The principle of action is something similar to the operation of the sealing machine for conservation.

Appearance of the device

Fixture "flashlight"

On this machine, the billets of "flashlights" or "cones" elements are manufactured, which may consist of 4, 6, 8 and more rods. According to the principle of operation, the machine is similar to "Twister", but here the blanks bend around the guide shaft, which forms a more correct and accurate configuration of the product.

Operating principle

Production of "Snail" with a drive

"Snail" with an electric drive facilitates the manufacture of curls and "currencies". This is especially valuable when the work is not "for the soul", but for the manufacture large number Simplicit products on the stream when working to order.

Below are the stages of the assembly of the machine for the gib rod with the maximum cross section of 10x10 mm. The engine capacity of 0.5 kW / 1000 rpm works at the limit of its capabilities. Performs 6 rollets of the shaft per minute. Snail segments are drawn from a round blank of Article 45 without heat treatment with a height of 25 mm and a thickness of 20 mm. The snail is nailed on the shaft on the bearings from the rear wheel of the motorcycle - 7204. The supporting roller is assigned to a rush to the groove. Pulleys are installed between the engine and the gearbox.

Below are the drawings of the snail segments.

Element snail 1.

Element snail 2.

Snail element 3.

Central Element Snail

For a more massive rod (from 12 mm), the engine power should be more kilowatta. The photographs below show a 2.2 kW engine machine, 1000 rpm, giving an output to the shaft of about 10 rpm. This is a machine for professional use. The used gearbox was applied, the matrix is \u200b\u200bcut out of the billet with a thickness of 30 mm - the most time-consuming process.

For cold forging, there will also need an anvil and hammer. Mountain is not needed, it is required only for hot forges.

Tip! Before starting work, draw a sketch of the future design to a variety. It will help to adjust the elements and not confuse when assembling.

From ancient times, Humanity is known for hot fork. The billet was shot down to increase plasticity subjected to molding heavy hammer blows. So received weapons and tools, homemade utensils and decorations.

Hot forging requires high qualifications and experience of a blacksmith, high labor, materials and complex equipment. Cold forging allows you to make products made of square and round rental, without installing expensive and cumbersome equipment and not by setting up complex technological processes.

Cold Forging Method

The way is to use important property Metal - plasticity. With a variety of mandrels and mechanical devices, the rod bends in different areas, twisted, forms various volumetric figures. Welding and plumbing operations are used as additional processing for connecting parts of blanks. The initial level machines are quite simple and are powered by the muscular power of the masters working on them. The technology is available for mastering in a home workshop.

The minimum set of blacksmith equipment for cold forging metal includes:

• Bending machines, or bent - serve to bend blanks at a given angle and radius.
• Twisters, or torsions - serve to twist the workpiece (or group of blanks) around the longitudinal axis
• Wave - serves to create periodic bends in different directions.
• The machine snail for forging is used to create spiral curls at the end of the rod.

Is it possible to master the cold forging yourself? Yes, for this, it is enough to have basic fastener skills, design and mechanical processing.

Many homemade masters made snail - a cold forging machine independently without using for this expensive components.

Types, device and principle of work Snail

Several varieties of the popular machine are used. All of them, regardless of the details of the snail device, use general principle Work. The strip or bar of the metal with force is pressed to a fixed pattern or to a movable snail legema, forcing the form to take a given drawing.

Distinguish:

• monolithic non-separable snail using a fixed metal pattern. Used to produce series of identical products
• removable design - the bend is carried out around the pins inserted into the holes on the massive plate. Suitable for the production of unique parts of complex configurations, limited cross-section of the rod.
• Collapsible snails with rotation - more complex in design, but allowing you to receive identical products complex form With great accuracy

Making a simple snail with your own hands

In the process of working on cold forging technology, significant efforts are applied. Therefore, before making a snail for a cold forging with your own hands, you will need to significantly strengthen the usual workbench or build a new one.

An independent assembly of the machine must be carried out on a tabletop made of plates with a thickness of at least 4 mm. Next, for the manufacture of a homemade snail for a cold forging, you will need a drawing. It is necessary to apply the contour of the future product, and enter inner side This contour of the outline of an unbearable template or segments of the collapsible.

How to make a snail for cold forging

• Monolithic non-separable
• Removable design
• Collapsible snail with rotation

Depending on the possibilities homemade Masters, Production plans, the number of different sizes can be chosen one of these versions.

Special attention should be paid to the development of the pattern of the template, because after welding to the plate, make adjustments to the dimensions and the configuration will be very difficult. The turns of the future curl should be positioned at a distance of 12-13 mm, given that 10 mm rods should fit into the formed grooves.

The base with a diameter of 80 cm is cut out of a plate with a thickness of 4 mm, then the drawing of a thickness of 3 mm is cut out from a strip from a strip from 3 mm and a pattern for curls. To facilitate bending, it should be carried out, then make the oblique chamfer on the upper side, and the bottom tooling to the base along the contour.

The base is attached to the bed with bolts or clamps. This fastener allows you to quickly apply different templates as needed.

Removable design

The template for cold forging is made of steel plate not thinner than 10 mm and is fastened on the basis of threaded connections. Production of the product starts with an internal curl. In the groove on the inner segment of the template, the end of the workpiece is pressed.

For insurance, you can additionally press it with a small clamp. Using a lever with a large shoulder, made of a rod with a cross section of 2 cm, the remaining part of the workpiece is screwed into the template. The design can be improved by applying the lever with a movable bearing fixed on it.

In this embodiment, the snail template, called the LEMEM, is fixed on a massive plate with a thickness of 4-10 mm, the change in the shape of the workpiece is made by rotating the shaft, in which its free end is fixed. The shaft rotates with the help of a lever or gate, welded to its top end. Lemeh can be performed from several segments interconnected by hinged fingers. The curvativity of the surface of the lemum is changing with special adjusting screws. On the surface of the base, you need to make a system of holes for fastening the lymum segments in a given drawing position.

Snail for cold forging with collapsible lemeh with hinged pins difficult to do in conditions of a home workshop. Faster and cheaper will book these parts in production. It is better to make a collapsible lemene without hinges. It is required to make a drawing of the template details and designate holes on it for fastening.

Based on the system of holes for fastening the parts of the lemhery in different positions providing various curvature.

Now you can, rearrange the fastenings from the hole in the hole, make curls of various radii.

Drawings snail for forging

Beginner masters often neglect the importance of the design study and make templates for cold forging on the eye. This may be enough to "feel metal" and understand the essence of the process with your own hands.

But if you want as a result of getting beautiful products, and even more so if the release of the series of the same elements was conceived, then in the manufacture of the machine, it is not necessary to do without accurate calculations of all parameters - angles and bend radii, the moments of rotation, limit efforts and others. The exact calculation will allow you to create a high-quality snail machine for a cold forging, which will serve for a long time and will delight the convenience of work and high-quality aesthetic products.

First a bit of physics. Forging as a process as a whole is the processing of metals using their heating. Molots, anvil, stoves, mighty blacksmiths in leather aprons - it's all about hot forging and a classic blacksmith. There are professionals, expensive equipment, individual premises - the occupation is not cheap. We are talking about a completely different process - cold forging.

If you figure it out, this forging is not forging. It would be more correct to be called flexion of metal rods, sometimes it is called "flexible". But, since the multiple rows of work masters for metal already established the term "art cold forging", then we will use generally accepted terms.

All artistic forging consists of solid bends, waves, curls - all of them are different, in a variety of combination. Hands Metal can not bend, even if it is the most soft. Therefore, the main single cold forging method is metal processing machine. For each metal element there is a tool.

Examples of art forging.

First of all, you need to get them, but first deal with the views of cold forging machines. The complexity of such equipment is low, the cost is also.

If you are going to engage in blacksmithing creativity for yourself, you will be quite sufficient to make a small manual drive. The pace of work on manual equipment is slow, but much lower the cost of manufacture and use. Electrical drives will be needed only in cases of commercial forging to order, then the sheep will cost the selection.

Special machines for cold forging are a whole bouquet of options, they are with manual control or with electric motors, homemade or purchased. In order to embody in the metal, all imaginable and inconceivable artistic ideas are enough for 5 - 7 species. At a minimum, half of them can be made independently.

The main thing is to remember that the cold metal forging on the shoulder of anyone who has a desire and perseverance. Before making a decision on the start of cold forging, you need to deal with some nuances of this technology and the types of special equipment.

Classification of machine tools

Types of cold forging machines.

Cold forged machines are divided into four main types:

• Twisters or snails Spirals with a flat surface and narrow nuclei, most often these machines are used for manual cold forging.
• Torsion types of devicesdesigned for the manufacture of twisted bulk spirals.
• Bending species - For spirals with wide cores.
• Inertia-stamping - for decorative homutics and processing the ends of all elements.

Before a detailed description of each view, we will pass through cold forging technologies, there are only three of them:

• Hood: This is a rolling and lengthening of the metal blank, the process is similar to the rolling rolling pin. In the forging in this way the pressing rollers work. This technology prepares legs, clamps, peaks.
• Torsion: twisting the parts along the axis, see below the detailed description.
• Bent: Metal bends in templates in different directions.

Twister or snails?

Description of forging machines.

Both those and others are the same. The most popular machine for cold forging among the wide masses of the forge public. In fact, at first glance, the machine seems too primitive.

But it simplicity is combined in half with genius:

• it is easy to do it yourself;
• he is cheap;
• it is extremely convenient in work;
• with it, you can make whole arrays of beautiful metal lace.

On the principle of operation, the Twisters are a type of bending machines, see them below, with some improvements, newcomers can safely work on them. In short, snail or twister is a striking machine for all possible criteria: ease of manufacture, wide artistic possibilities, cheapness and convenience in work, there are simply no such.

Twisters are found in two engineering options:

This snail has weaknesses, where without it. It's all the case in the folding lemery: important and the right material from which it needs to be done, and the complexity of manufacturing the joints of the LEMERY units. These articulations should be extremely accurate - it is the form of a curl form. In the design and articulation material, it is necessary to take into account multiple repetitions of turns with a serious workload. The second and last weak place is the eccentric clamp items.

Taking into account the frequency of use of the snail and its weaknesses, it will be the most reasonable to buy it, and not to do it yourself. If we are talking about the debut in a cold forged, and the selection of the machine is done for an absolute novice, then the most optimal option There will be a second engineering snail version.

• Popularity champion and positive moments In work! Limping snail with a fixed pattern and bypass roller. In essence, it is pipe bender. It is necessary to immediately notice that this version of labor productivity is inferior to a twister with a gate and a lemeh. Secondly, no countertop is suitable for him, there will be a real steel bed with fasteners on the supporting surface. I will not put the bed at home: you can work on the lever snail only in the workshop.

Machine to give the embossed surface.

Another feature of the lever snail is a slow pace of work. You can twist 3 - 4 curls, slightly less than with a collar snail. However, the pluses of the lever snap outweigh all its minuses:

• All items of the machine can be made of conventional steel.
• Instead of a clamping roller, which is not made from conventional steel, you can use the bearing.
• The material of the bed and other parts allows you to count on long use of the machine.
• A greater variety of curls - you can change their shapes with bends in both directions (in the first version of the snail it is impossible).
• It is more convenient to work with the ends of the parts that can be attached.

On the lever twister you can work with metal stripes laid by plastics. This is considered the most advantage of the machine, as it is impossible to work on other devices with stripes.

In this champion's subsection, you can make a small champion resume in the form of a board of novice: in debut artworks on cold forged, it is better to start with a lever twister - a snail with a fixed pattern and a ocker roller.

Torsions from the word torso , torsion machines

Curl technology.

Twisting along the torso, and this is said much. The torsion machine for cold forging is designed for the screw longitudinal twisting of the rods. If you figure it out, you can twist them without a machine: it is enough to clamp one end in the vice, substitute the chumbach to the other end, twist the rod in the guide tube. Everything is simple, but we say today about art forging, Therefore, the quality of twist taking into account the smallest nuances is the number one requirement. Therefore, twist the rods, although along, even across, it is better with the help of machines.

Unlike twisters, torsion equipment can be made independently, the overwhelming majority of torsions in the people are homemade. For these machines, we also need a durable bed with the same durable fasteners on the support surface. The rods in the right torsions are held in cartridges with a square cross section, which are fixed by the clamps.

Everything would be elementary, if among the masters of the cold forging were not considered special chic artistic figures like baskets, flashlights or cones - curly thickening from several twisted rods. All of them are called mysteriously - filaments. For their manufacturer in Toriras, it is necessary to insert a bit of smaller rods, most often 4 - 5 pieces.

With cones and lanterns you will have to tinker - branches from the rods need to be sewn manually, which is very difficult and requires a decent skill. For high-quality filaments, the pride of the Kuznetsov, special grandmas with spindles with screw feed are attached to the torsion. The troublesome elements, but for the embodiment of artistic plans and aesthetics of metals - without filaments nowhere.

Stamps for bending.

Attention! Torsion machines - the only blacksmithing equipment For cold forging, in which the electric drive is justified and is advisable for any scope of work. This is true, it hurts tedious and tedious work with a manual spindle drive. But this is not the main reason. Manual way It is impossible to achieve a uniform twist, for this you need to be very uniform rotation.

Inertia-stamping machines

This type of equipment resembles the press or pressing rollers, which young masters sometimes neglect. And in vain: Without shaped homutics for connecting parts and decorated tips, work will never have aesthetic look. These presss work as a flywheel, in which the battlefield beats at the place of the stamp. Decorative details are small, the accuracy of their manufacture should be very high, so this kind of machines do not even need to try to make it yourself.

Everything is good, but only inertia-stamping presses are expensive pleasure. But here you can find a solution, let's call it "integrated blacksmithing solution." Of different kind Tips are very easy to make hot forging. For this not necessarily be experienced master. Either go to visit to the workshop of hot forgeds or the very rash forge - You can easily make it easier to make it easier. For such a shallow work, its separate forge is not needed, things are all anything - heat the metal.

Bending or bent

In practice, bending machines are more often called "bent". But among the masters forging, the gnutik is the most popular machine for cold forging, which makes metal waves and zigzags. This equipment is desktop and pretty simple in its design. But it is better to buy it than to do it yourself. The fact is that in this form of forging you need a very high accuracy of the processing of parts. It is worth the abnorm for cold forging at all inexpensive, especially for pipes less than 12 - 16 mm.

Another thing is flexible, which is much easier than the bend: it is a fold of a rod under the desired angle. Figures are performed using templates. First draw a drawing for the template, then an curl is welded onto the steel plate. Forging is to drag the product through all curls.

Manual machines for cold forging in the form of flexible make with their own hands, it is still possible. The only detail of such a machine that will need to buy is rollers. They need to be done only from special steel: or instrumental, or chromonichel. Equipment for cold forges can be performed from brackets and arcs with limiters that will determine the circuit of the wave. The waves can then get a wide variety of what is required.

Machine with their own hands

Machine for flexible rods.

A homemade tool for cold forging is quite real, but the time and effort of its manufacture will take a lot. Therefore, the decision must be suspended, and the preparation, including drawings, should be serious and full. The most suitable place can be a garage of Shed, or Hozblock. The design of the machine depends only on one factor: what are you going to do what products to release?

No need to forget that many forging elements can be performed without special devices. For example, using an ordinary pipe bender, which is quite suitable as a variant of a simplified machine for a cold forging - with him a lot of things can be done.

Still need to understand that universal Machine For cold forging, which would have done at least three different elements, there is no nature in nature. Most often, do your own hands: it is popular, it allows you to make a variety of curls and, in the end, easy to perform. The second on the frequency of use at home is a homemade bending machine.

He is as simple and inexpensive. At the request "how to make machines for cold forging" you will get a huge number of links to videos with the tips "from experienced". Most of them are in the case and from the soul, they will help in making final decisions.

Connection of parts and painting

Now all the curls need to be collected in a single canvas. The work is not easy, but very grateful: it is at this stage that the main artistic idea begins to be implemented. Meanwhile, at this stage you can easily spoil everything. Make it easy: start connecting the parts with welding, and then go through the grinding for stripping.

But we have already spoken about the professional ambition of the masters of cold forging, which can only be welcomed. A much more effectory will look at special p-shaped clamps that are stamped on inertial machines. Do not be lazy, but to work well with the homutics - this is the key to the successful completion of the forging of the product.

Metal twist on the machine.

Now about painting. Thank God, now there is nothing to paint: thanks to modern construction technologies, on sale great amount paints for every taste, wallet and, most importantly, appointment. Colors for metals - countless number. Most often used special acrylic paints on metal or blacksmith enamel.

Very often, at completely unknown reasons, the Master of Forgeless Care prefer the finishing paint coating with a pigment from a blacksmithing patina - "under ancient", showing the amazing unanimity in tastes. If you are a customer forging, then you need to stop the masters in time to offer him your color version and coverage textures. Well, if seriously, who said that the forging should be dark and under ancient? And white? Color? This is where the immense space for the most bold artistic solutions.

Summary like oil

Types of stamps and ready curls.

A good story is always easy to finish - the findings fall on themselves, within the framework of logic and priorities.

In our review of cold forging technology, the slightness of the conclusions is:

• Cold forging is a wonderful technology that allows you to combine that it is impossible to combine into other processes:
• practical benefit in the economy;
• the possibility of artistic creativity;
• invention and application of own engineering finds;
• simplicity and reality of execution for beginners;
• improving self-esteem as a master and as a tenant house with elements of artistic forging.
• Fixtures for cold forging can be independently and high quality, it is better to start with snail and flexing machines.
• Manual equipment is more expedient to do with a manual drive. The electrical use option is too resource. The only appearance of the machine, which is better to do immediately with the electric drive - torsion. The quality of twisting of the rod will be much higher in this case.
• In the manufacture of forged products, the cold method will not prevent "Help" from hot forges. The machine for tips and other small decorative elements cannot be made independently, and there is a lot of money purchased. Our advice is to perform a decorative trifle with hot forges. Small and neat horn in the farm will not hurt. And will contribute to professional growth: start with cold forging, come to this blacksmith skill ...
• Do not close in the stereotypical painting of forged products "under ancient". Modern paints and widespread eclectics in design make it possible the most unexpected color and textured solutions in the work on the metal.

Metal curls made by cold forging are used to decorate exterior elements.

Products are popular with owners country cottages and communal services engaged in architectural arrangement of common areas.

You can also apply these elements in the manufacture of individual devices -, outdoor furniture, and even dishes.

Such a decor, and especially finished goods, very expensive. Even the standard sets put on the stream and are sold in stores - have a hot price. What is already talking about products made by individual order.

Therefore, many homemade masters try to create similar creations on their own. Moreover, "cold forging with their own hands" does not imply a classic blacksmith technology. Processing the material of the workpiece is carried out without the use of heating and working with a blacksmith hammer. So, it can be performed at home.

However, such a job requires a special tool - a cold forged beam. The equipment is offered in stores, or is manufactured in workshops by individual order. A set for universal metal processing is a whole complex of various devices.

First, it is a truly unique tool that allows you to create highly artistic products, without hammer, blacksmith horn and anvil.

Secondly, from simple metal Such adaptations do not, otherwise the machine will fail at the first load. It became, high-quality and durable steel increases the price.

Consider various homemade fixtures for cold forging

Let's start with the principle of operation of the instrument:
The billet (metal circle, square or band) is installed in the machine between the guides. With the help of lever manual, or gear electric drive, a change in geometric shape occurs.

There are several standard fixtures that are templates for cold forging.

Device "Gnutic".

This is an improved counterpart. With it, the workpiece bends under the programmed angle. It can be both solid and form geometric figures. Decorative element It happens flat or voluminous, and all this makes one tool. With the help of the gnut, you can perform an arc from a straight blank.
