Instruments

The electric saw is the unavailable tool in the country area or in a personal house. She simply co-collapses with a cut of thick branches, boards and various wood material. Even the most reliable tool has its own degree of wear, sometimes you need to correct small or large breakdowns. Repair of electric saw naughty Hands are likely exclusively in some cases and in the presence of certain abilities and inventory. Often the instrument has to be given to the service. But there are some breakdowns that are simply corrected without the help of others.

Construction Review Electrical Circuit

In order to seize the ability to repair electric copies, you need to realize their design. The main element that produces cutting material is the saw chain, which drives the motor. The chain itself is a joint cutting links, which are bonded in themselves with hinges. The movement of the chain is made on the plate, which is called the tire. Electro saws from the grinder with their own hands. This detail is done from the steel of the highest property, which is not subject to chips, scratches and corrosion - this is the main indicator of the tool properties. Tires are highlighted in designs:

• welded;
• solid with a removable tip;
• whole with tip made of carbide materials.

The welded tire is something similar to the "sandwich", which is welded from 3 constituent parts into one, with all this in the design, the slave asterisk is inserted. One-piece design with a replaceable tip is a product of the 1st sheet, normal for long-length tools. In such a tire, the main load falls on the roller bearing of the slave sprocket. One-piece configuration allows you to lower the losses for friction by 8-10%. If a tool with a solid tire of solid alloy materials, then it is normally suitable for working with the highest load, also for operation in the criteria for the presence of a huge amount of sand, dust and mud.

1. The chain emission from the grinder with their own hands. When working with an electric saw, at least one configuration must be kept in the head about the ability of the "reverse strike". Garbage tool towards performing human work. Such a situation appears if the very end of the saw tire rests on the material being processed. To avoid injuries in such a situation, manufacturers equip saws automatic chain brake.

2. Automatic chain brake is still referred to as inertial drives, which works due to a shield located in front of the left hand of the person performing the work. Before the work, this shield is put to the position closer to the hand, so that if necessary, it was activated rapidly. If the moment of the reverse strike appears, the operator's hand rests on this shield and the chain stops. The position changes and due to the inertia arising from impact. Such a system allows you to reduce the possibility of repairing electric chains, because during the impact it will not be damaged by its main mechanism.

3. Another system that prevents wear and breakage is automatic lubrication chain. In a special reservoir, the oil is poured, which during operation saws is transmitted through the oil pump to the slave asterisk and the chain. Some models even have an oil supply controller, because with different intensity of work, it is necessary to various quantities. For example, the repair of the electric saw blade involves an inspection of the oil supply system.

4. The chain saws with an electronic motor have some shortcomings or weak places. Some of them are the design of the gearbox. The torque is transmitted to the chain through a gearbox, which has a rigid bundle with an anchor of an electronic motor. This design transmits all loads on the engine, in other words, if solid inserts are contained in the workpiece or the saw chain fastened, it will not be so smoothly sliding on the surface. The result of this will be overheated by the motor or wear of some of its details. The chain emission is significantly how to connect the washing machine with your own hands to. As a preventive measure, you need to sharpen the saw in time and not to put pressure on it when working. Often enter the service repair of the power saw of the Parma with this kind of defects.

5. 2nd weak spot saw with an electronic motor - dependence on the voltage in the network. If it falls, the load on the engine is growing, in models that are not equipped with a thermal protection motor, the growing load leads to its combustion. Yes, and protection against temperature increase has shortcomings, because with a low voltage it works, lowering performance. For example, the repair of the electrical saw intercol is often reduced only to an increase in the voltage in the network, after that the tool works properly.

Overview of possible malfunctions

1. If the saw does not work, need to check The presence of nutrition, the integrity of the wires and connections.
2. If everything is in order in the power supply, you need to check the chain brake, which overlaps the operation of the tool. To eliminate this problem, you need to move the brake shield to another position.
3. If the measures described above did not turn on the saw, then need to check Cable integrity and plug.
4. If the power of the saw decreased, the performance fell, you need to change coal brushes, which apparently wear out.
5. Quite often the chain begins to stop not going away, but through a certain time lumen. The longer the saw was operated, the more this temporary clearance becomes. To get rid of this task, you need to change the feed brake ribbon, which was exhausted after time.
6. Often in the work of the saws the opposite, cutting ear sound. Such sound often occurs due to the lack of oil in the mechanism or due to the contamination of the grooves conductive it. The chain electric saw - it saws how to make a feeder for birds with your own hands. Remove the malfunction simply - pour oil and clean the furrows.
7. It is fundamentally used when repairing only unique spare parts that are recommended by the manufacturer. If you use spare parts from Posatronyi companies, it often leads to a tool breakdowns or the emergence of unsafe situations.
8. If there are damage to the case, then for its safety, the saw must be passed into the repair.
9. It is impossible to replace the cutting parts of the tool that are not recommended by the manufacturer are either not suitable in design.

Sharpening electric saw

One of the elements of the saw, followed by independently - chain. Chain electrolysed 2 years of operation, whether the apartment is planned with their own hands. It must be sharpened prophylactically, since in case of tightening with this process, the repair of the chain electronics will not be possible to produce with their own hands. It must be given to the service where the sharpening will produce on professional machines.

1. Extension of the service life of the saw element:

• before starting work, you must make sure that there are no solid metal objects in the workpiece. If there is a contact of the cutting element with a metal object, it will remain a zubrin or chip on the chain, which is no longer possible;

• it is impossible to carry out work on Earth, since the deepening into the ground will score oil grooves, as a result of which the chain will remain without normal lubricant and is faster to wear;
• it is necessary to monitor the wedge of the saw, it cannot be allowed, as it overheats the metal and reduces the duration of its service.

2. How to determine that the saw is needed sharpening. To do this, it is enough to pay attention to chips - if they are small and slightly darker, then the chain fastened. This is explained by the fact that blunt edges do not remove the necessary cutting layer, it leads to grinding chips. Also, the quality of the sharpening saws is determined on the basis of a visual inspection, there should be no radii on the saw part, damage in the form of dotted sites, the shape of the tooth and the cutting edge should be the same as on a new tool.

If all these factors do not meet the necessary requirements, the saw requires sharpening. If you continue to work on a stupid saw, then this is reflected in performance, as well as on the period of sawing saw. With sharpened elements, the load on the engine increases, it overheats and all its elements wear out the faster of the specified period.

3. How to sharpen electric saw yourself:

• for sharpening, a special tool is needed, this is a set of circular and oval files, mandrel and caliber;
• sometimes the set additionally includes a hook for cleaning the slot chains from chips;
• round file combines a mandrel;
• flat-shaped file and caliber are used separately;
• chain point on the tire saw itself;

• the mandrel is put on the edge of the cutting tooth, while take into account the chamfer sharpening;
• the sharpening angle is set to 30 or 10to, the corner is set - this is the most difficult process of editing, since when setting an incorrect angle tool will be spoiled;

• the file with sharpening is exhibited perpendicular to the tank, it performs a little over the tooth when sharpening;
• sharpening passes in one direction, that is, only by the forward movement, not reciprocating;
• when one tooth is sharpened, the chain is scrolled and proceed to the sharpening of the next tooth;
• after all the edges of the teeth are processed after the file, the processing of the restrictive cut - the protrusion on the chain that does not have cutting edges, it is located on a single plate with the tooth. The function of this part is to form shut down when cutting;

• if the cut limiters spend greatly, the chain will not cut, but only slide, if too bueled, the tree will jam the cutting part of the tool;
• the edit of the cut limiters is made by caliber, it is applied to the edge of cutting teeth, while the end plank is at one level with the limiter;
• if the limiter acts, then it must be entrusted, this is made by the usual Flat Form file;
• the file for the limiter is moved in the perpendicular plane in one direction.

4. Sharpening saws on the machine:

• for sharpening on the machine, the chain is removed from the bus;
• the chain is installed on the guide machine and stretch the roller and ratchet, which hold it for the cutting tooth;
• there is a vehicle in the machine that sets the sharpening angle;
• the abrasive circle is lowered, with its help, a slight layer of metal is removed - approximately a few tenths of millimeters. This is the process of editing and sharpening chains;
• after editing one tooth, the guide is rearranged to the next and so on;
• this type of sharpening allows you to withstand the rigid framework and sharpening tools;
• if there is a desire to purchase such a machine for yourself, it is recommended to purchase a non-electric version of its option, but manual, since its value is significantly lower. The machine allows you to move the repair of the electroplated bosch and any other manufacturers.

Some rules for working with electric copies

1. Chain electronics are designed to work with a maximum speed indicator, you should always work with a fully open throttle, it will increase productivity.
2. Do not cut at right angles from ourselves, you should keep the saw a bit at an angle from the case.
3. It is necessary to adhere to the repair instructions for electric copies, as well as acquire only those parts, which recommended by the manufacturer.
4. Before transporting the saw, you need to turn off the engine, a tire with a chain with carrying is kept for yourself, you must pack the saw into the casing before transportation.
5. Do not work with a saw above the level of the shoulders, as it raises the risk of an accident.
6. If the saw is jammed in the material, then it is necessary to extract it from there very carefully. The steering force acting on the saw increases with the top clamp, which is quite dangerous for the operator.
7. When working with a log in the frame of subtle bans, it should be done very carefully, since the thin material in some cases is clamped and folded towards the person performing the person.
8. It is strictly forbidden to use a faulty, non-adjusted or not fully assembled tool.
9. Before you start, it is necessary to check the help of the saw switch.
10. It is necessary to constantly monitor the tension of the chain, since if it is stretched bad, it increases the risk of her scope from the guides, it leads not only to injury, but also to break the device.
11. Repair electrolysed partner, like any other saws, is recommended to be carried out in a specialized service center, as independent repair leads to serious problems in the future.

When working at home, you should always be able to make a tool with your own hands. The homemade circular will fulfill its duties not worse than the factory analogue, and its maintenance and dismantling will be much easier. In special cases, the circular saw can be converted into a radial or bulgarian, which is their very pleasant moments.

Circular saw can be made independently, for this you need to have good drawings and tools.

Working with saw and baccoon

Tools and materials:

• bulgarian 150-180 mm;
• drill;
• self-tapping screw;
• steel clamps;
• steel sheet;
• pliers.

Before making a circular one, you need to try to make it from other tools. Most often, the process is organized by the Bulgarian, because It can be removed much faster and easier than any other counterparts.

The easiest option is best spoiled tool. It will be necessary for it using metal screws to fasten the tool to the base. If you wish, you can make a drill through holes and tighten with bolts and nuts, which will be much more reliable in work, because The tool is no longer sneaking the thread in case of strong tension. The only nuance that should be taken into account is the factory unbalance of the instrument, due to which it will be necessary to fix it in a thorough way, in order not to be even a small probability of skills.

If you wish, you can complicate this design, besides it will save the tool from unnecessary interventions inward. For fastening, steel clamps will be required, which clamping a tool in 3-4 points, and then fixed on the bolts from 2 sides. This design is very reliable, but special attention should be paid to the quality of fixation to avoid even small misunderstandings.

For those cases when the tool is manufactured stationary, you can use more powerful ECM options. Bulgarian herself is fastened to a lower reducer with bolts or screws (it depends on the possibility of making a joint without damage to the instrument, because sometimes the places of fasteners do not match), after which they are installed together on the worktop and are fastened to the most qualitative way.

The most reliable way will be at the same time the most difficult, for the support of Tokary-Merzernel will need. In his task, it only includes a special detail that would fit the grinders and countertops to their parameters. This coupling method is the most reliable, moreover, even microscopic movements are excluded, which turns out to achieve far from each factory instrument.

It should be considered that in any case the protective cover is removed, and instead it is made homemade from sheet steel. Molding for casing to use will already be impossible due to the fact that it is used for the hitch, and the homemade should be mounted directly to the tabletop. For its manufacture, it is necessary to cut a semicircle from sheet steel, which is bent the tip and clamping the pliers. This design will withstand any surprises after it is possible to fasten it.

When choosing a grinder, you need to be extremely attentive so that the number of revolutions is small, and the power is high. If the speed exceeds 4500 vol. \\ Min, you will have to use lower gearboxes, because Otherwise, the cutters will be very quickly set.

It is very important to remember that in any case the circular card made from the grinder can not be redone back, because For this reason, daily at all points of the world people fall into hospitals with injuries of varying severity. Even if the Bulgarian is urgently needed, but there is no other option, it is better to suffer, for even the factory defense will not save.

Alteration saw

Tools and materials:

Circular saws scheme for circular saw.

• chain Saw;
• steel flat roller;
• nozzle for cutters;
• lower reducer;
• welding machine.

Electric copies and chainsaws are a gift from the 20th century, which is very harmonious fits into life, but there are such situations when they are desirable to remake that it is not easy enough. It should be noted in advance that this alteration is a momentary character, but if you wish, you can repeat it once again without any damage (the replacement will require some time).

In order for the circular to be a circular, it is necessary only at the very end of the boom to weld the rolling wheel, and the end itself to cut. The wheel must perfectly repeat the contour of the sliced \u200b\u200belement so that the chain does not stretch when moving and did not fall.

On the side of the wheel attached an adapter for cutters. This adapter is removable so that when cutting the chain did not occur.

With high-quality refinement, the wheel will not harm the working qualities of chainsaws in the absence of mills at this moment. In addition, the base operating speed well suggests without serious third-party improvements.

Using an electric motor

Tools and materials:

• asynchronous engine;
• steel sheet;
• wires;
• lower reducer;
• bolts with nuts;
• milling adapter;
• pliers.

There are many electric motors, and collector, synchronous and asynchronous motors are most popular. This is the asynchronous option for this activity, because It has the highest capacity indicators, small turns and a huge stock of endurance.

Make a circular from it will be very simple, so everything can be done in stages:

1. The engine 4000-4500 is selected about. \\ Min, with a capacity of 2-3 kW and power outlet 220 V. If the engine is not found with such parameters, it will have to use a gearbox that will result in the number of revolutions to the desired one. The connection is made using bolts with nuts, but it is advisable to do not resort to self-drawers, because they can cause significant damage.
2. Now you should choose which nozzle will be: chains or cutters. The cutters are rapidly stepping, but give a thinner slice, thereby obtaining greater accuracy. Chains are rapidly slower, but when they work several times more sawdust. Most often preferences are given to cutters, for the basic price of wood with them goes a little cheaper, and the quality of cutting is higher.
3. On the shaft of the motor attached an adapter for cutters. If the gearbox was used, it is necessary to mount on the gearbox. In this case, the joint is made without welding so that, if necessary, it was possible to replace the nozzle on any perceptor.

At the very end, a protective casing made of sheet steel according to the method described above is manufactured. The casing is attached to the reducer or a motor man so that there is no complications.

Circular electroopers - extremely necessary tools for household. Thanks to its technical and functional properties, no furniture production or carpentry shop is not necessary without them. Yes, and in private householdings there are many tasks that it will be more expedient to solve with their participation. The only thing today is limited to their operation, this is the cost, which is growing every year, as well as the need for a person. One way to overcome this barrier and acquire such universal assistants is considered to build a self-made disk saw,

Considering the load and duration of the working cycle of electric saw, for their home production it will take no less reliable base electrical appliance. Folk crafts are advised as it to use a grinder or a corner-glare machine, which is almost everyone. Its traction potential will be enough for sawing the forest, dissolving the bars on the rails and other tasks that most users put in front of it. Consider several ways to make electric cooks at home.

Disk electrolysed with your own hands: the easiest way to manufacture

In order to start an assembly of homemakes, you will need:

• metal clamps;
• electric drill;
• toothed;
• several pieces of metal corner;
• bolt ties modifications m3 or m5;
• operable gearbox;
• high-strength rods;
• wrench.

As a power base of the future, the engine will perform an engine from the household Bulgarian.

Stroke work step by step

1. with the grinder pre-dismantle the disk installed before;
2. a disc with woodworking teeth is taken, which is tightened with corners. There is a gap of several millimeters, which are regulated by a bolt tie;
3. bulgarian housing - future electric copies are tightened by clamps. At the bottom of the tool, a double metal ribbon with a thickness of at least 1.5 mm is passed;
4. reducer Bulgarian pre-disassembled. It needs to make holes for fastening the handle. The last part can be made of a metal tube, the form of which should be slightly rounded;
5. to adjust the gaps between the side focus and the base surface in the gearbox, 4 holes are drilled to screw the bolts;
6. bolts to the gearbox is attached to the handle. Its outstanding outward electropulips end the horizontal position, drill holes and served axis. In the event that the handle is a donom form, an adapter is installed between the handle and the gearbox - the tube of thick-walled metal;
7. pruts are cut at 6 cm of the workpiece, which is given a loop-shaped form;
8. front stops are fixed by washers than the clearance is adjusted;
9. the handle joins the housing with an electric motor.

When complementing, such electroopers from the grinder with their own hands with a stationary base from chipboard or stable plywood, you can make stationary disk electronics for the workbench or desktop.

In both options, it is very important not to be mistaken with the choice of disk and correctly calculate the gear ratio. It is advisable to focus on single-phase asynchronous motors, which are equipped with most of the corner-glasses. Three-phase motor systems, which can also take place in such a design, do not apply without additional capacitors. A separate button can be displayed as a trigger capacitor. In this option, you will need to think over the additional grounding and check the electrical safety of the homemade.

Chain Electronized Bulgarian: Step-by-step instructions

In order to recreate the chain electrical cooking on the basis of a working grinder, we will need:

• bulgarian herself;
• the leading asterisk, which is best to buy a new one, but if there is a good spare parts with an old saw, you can restrict ourselves to the option;
• metal to create a bracket to which the guide will be connected;
• a set of saw headset from the tire and chain;
• a set of tools, including drill;
• bolts.

The assembly process looks like this:

1. 1. unscrew the saw blade with a grinder;
   2. make holes in the lower part of the metal casing;
   3. bolts attach a bracket to a protective shield;

1. 1. the engine is screwed up on the shaft;

1. behind the screed brackets fix the guide;
2. after the chain is hoping and polished, the bracket bolts are tightly fixed.

After that, you can proceed to work.

Advantages and disadvantages of self-made electric saws from the Bulgarian

Electric saws that today can not only buy in the store, but also to do at home, in addition to their main advantage - low costs on their production, have a lot of weaknesses. Namely:

• the low level of security for the health and life of the operator of the operator - in the homemakes there is no protection against the recoil, which in factory electric copies takes on the inertial brake of the chain. And this increases the likelihood of injuries and injury;
• the briefness of the tire chain elements due to the absence of automatic lubrication. The only way out in this situation will periodically dip the homemade saw into the tank with chain oil;
• high risk of overheating of the motor from the grinder due to overload and long-lasting operation.

Pilocarm - an indispensable assistant in everyday life and professional carpentry. Excellent copes with those challenges where the efforts of a conventional disc or chain electronicle will not be enough. Among its areas of use is the longitudinal sawmilling and processing of logs, furniture production, construction, industrial wood harvesting. Even with such a large list of advantages, this acquisition can afford not everyone: its current price has a lot of pocket and gives the prospect of buying for many years ahead. One of the ways to solve this problem is the self-catering of electric saw, popular not only among lovers, but also from professionals. In view of the relevance of this topic, we consider one of the options for creating a sawmill of electric copies with your own hands.

Homemade sawmills from electric saw: design options

Among the entire diversity of self-seals from electric copies, sawmills - the most popular and common product, which folk craftsmen produce not the first year. Factory analogues of such devices are quite expensive due to their high performance. They are able to process thousands of forest cubes per day. When there are no such scales of woodworking, no finance, you can pay attention to one of the 3 types of homemade panels:

• ribbon; Have a complex design, but adapted to any operating conditions.
• disk; Quite simple in the assembly, but not reliable, why the amateurs are in demand. Electronical-based disk sawmills are quite common in everyday life, produced and universal on the tasks performed;
• chain.

In view of this, we will stop in detail on their manufacturing technology.

Electrical disk sawmill: Detailed description and drawings

Before making self-made sawmills from electric saw, you need to decide on:

• materials that will be processed on this machine;
• volumes of workpiece;
• the future location of homemade.

Separate attention should be paid to the choice of disk cloth. Disks with a size of 400-500 mm, which are most often used in modern circular, suitable for these purposes more than. And solve the problem with sawdust can be using a disk with a minimum thickness.

Device disk sawmills based on electric saw

The construction of any self-made sawmill-based sawmills implies:

• frame element - carrier part that connects all other parts together;

• motor part - It is desirable to dwell on three-phase modifications. Electric saw: household models that feed on the network with a voltage of 220 V can be lowered;
• cutting headset - the disc is installed in one of the planes - horizontal or vertical;
• the carrier node - the usual workbench or table, on which the logs will be supplied by hand. For more complex design, complement the mobile carriage;
• adjustment mechanism - controls the electrical system of homemakes, starts and turns off the motor. Most often is located on the frame.

Sequence of assembly

• mounting frame frame - its sizes are selected individually given the disk diameter and the dimensions of the motor. It is connected to 2 bearings and drilled 4 holes for aggregation with an electric motor;
• the plane on which lumber will be supplied. For small in terms of work, you can use the finished stationary workbench or work surface, which must be installed strictly horizontally. It is very important that its longitudinal axis corresponds to the axis of the frame basis;
• mobile carriage - its approximate size should reach 1 m. Mobility will produce wheels that will be installed at the end of the corner;
• the engine aggregation with the disk is better to give preference to those inhibitors, where the height of the knife unit could be configured manually. To do this, the carriage is attached to the carriage, to which a metal chaserler weld. Through metal linings, they attract the pipes to the pipes. Lifting or lowering will be made by two steel rods. The moving position of the engine will ensure the bike stars connected to the ends with the motor, associated with it through the rod with carvings.

To improve the results of the efforts of the homemade can be strengthened by a second disk knife. As in industrial analogues, their location should be strictly perpendicular to each other. For pilots with a power of over 3 kW, the additional traction device will not need. Otherwise, the second motor is taken and a second drive is created.

Unlike standard chainsaws, self-made electric saw on the battery is noticeably lagging behind in power. However, it has other obvious advantages: compact dimensions and mobility - electric saw can be easily disassembled and put in a backpack. In general, despite the low power, the benefit from it will still be.

For the manufacture of homemade electroopers, a piece of sheet metal is required with a thickness of 3 mm, from which it will be necessary to cut the base for the case. You will also need a short tire, fastening elements and sections of the saw chain.

The main stages of work

The first thing we cut the housing to which the electric motor will be fastened. Then, on the lathe, pull the steel pulley to the drive shaft of the engine. For the manufacture of homemade battery electroopers, a bus of small sizes and a segment of a suitable length circuit will be required.

Then it is necessary to make a wooden handle in which it will be necessary to drill a hole and set the power on / off button.

At the next stage, 18650 accumulatory batteries make a whole battery pack 24V. Contact plates weld with contact welding. The complete charge of the battery is enough for one hour of continuous operation. Electrical saw.

From a piece of steel round tube, you need to make a stubborn handle to make it easier to cut. Then proceed to the assembly of the whole structure. The result was a compact electron, which operates on the battery.
