Cold forging is impossible without special forging equipment. Let's take a look at the types of fixtures and the shapes that can be obtained with their help. We have prepared drawings and thematic videos for you. We will also consider the sequence of manufacturing the machine for cold forging do it yourself.

If you are just going to set up a cold forging workshop and want to avoid high costs, then self-production machines and fixtures will help you create your small business without undue cost.

Basic fixtures and machines

Cold forging machines are mainly designed for arc or angle bending and twisting. They can be manual or electrically operated.

The main types of machines and devices for cold forging:

• Gnutik
• Twister
• Snail
• globe
• Wave
• Lantern

Device "Gnutik"

Purchased or self-made "Gnutik" is a universal device that allows you to get an arc or angle from a rod. It is a base with a slider on which a stop with an angle (90 ° or another, if necessary) and two cylindrical fixed stops is fixed. By moving the slider and corner stop, the rod is bent at an angle. To obtain the arc, a third cylinder is provided that rotates on the side opposite from the corner stop.

The device can be carried out on a horizontal or vertical platform.

Axonometry of the "Gnutik" device - vertical arrangement

To scale the dimensions, here is a drawing of the bottom bar of this "Gnut".

This is how a homemade "Gnutik" looks like:

Device "Twister"

"Twister" - a tool for twisting bars, mostly square, along the longitudinal axis. This simple device can be manual or electric. Principle of operation: both ends of the rod are fixed, then one fastener begins to turn, twisting the metal to the required shape.

The appearance of a purchased hand-held "Twister"

Look at a photo of a homemade "Twister" with an electric drive, assembled using used electrical equipment:

For the manufacture of "Lanterns" and "Cones" there is a special machine, but for a start, you can use the "Twister", as shown in the video (in English, but everything is very clear).

"Snail" device

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

One of the design options: 1 - snail share; 2 - the basis of the machine; 3 - pressure roller; 4 - a lever for controlling the pressure roller; 5 - fastening the base; 6 - pin for fixing the plowshares; 7 - groove for the pinch roller; 8 - axis of the control lever; 9 - spring for pressing the roller; 10 - clamp for the workpiece; 11 - snail leading share; 12 - main axis; 13 - levers

The result should be the following device:

Another one lightweight construction to bend rolled products with a cross section of up to 12 mm:

1 - segment of the cochlea; 2 - eccentric; 3 - handle; 4 - base; 5 - guide skids; 6 - axis; 7 - slider; 8 - axle nut; 9 - roller mounting axis; 10 - roller; 11 - drive axle; 12 - eccentric guide; 13 - the central segment of the cochlea; 14 - eccentric lamb; 15 - main leg; 16 - connecting pin of the cochlea segments; 17 - adjusting screw; 18 - connecting ear of the cochlea segments

Often the "Snail" device is made on a support, especially if thick rolled products need to be bent.

Several helpful videos on homemade machines"Snails".

Machine operation

We will talk more about such constructions below.

Fixture "Globe"

Such a device looks like a school protractor and is designed to make arcs with a large bending radius from a strip, square, circle or hexagon. First, one end of the workpiece is fixed with a bend, then it is bent along the entire length according to the template. The principle of operation is somewhat similar to the operation of a seaming machine for conservation.

Device appearance

In the video work on the "Globe"

Using exclusively muscular strength, the arc large diameter can be made on a template screwed or welded to the workbench. It is good to bend a strip on it, a thin-walled pipe, etc.

Sample

"Wave" device

You can get wavy products from a workpiece of a round, square, hexagonal section or a tube using the "Wave" device. The deformation of the workpiece occurs between the vertical rolls by scrolling.

"Flashlight" device

This machine is used to make blanks for the elements "Lanterns" or "Cones", which can consist of 4, 6, 8 or more rods. By the principle of operation, the machine is similar to the "Twister", but here the workpieces are bent around the guide shaft, which forms a more correct and accurate configuration of the product.

Device for cold forging element "Clamp"

The cold forging element "Clamp" is designed to fix other structural elements together.

The device for bending "Clamp" can be made according to the attached drawings.

Accessories for performing "crow's feet"

"Goose foot" - flattening with the application of beautiful notches at the ends of the blanks to make the design more elegant or to reduce the thickness for various joints.

The ends of the elements are decorated with a "goose foot"

This operation can be performed using a machine tool with a die or attachment and a heavy forging hammer on the anvil. We provide both options in video materials.

Operating principle

Making a "snail" with a drive

The electrically driven snail facilitates the production of curls and currencies. This is especially valuable when the work is not "for the soul", but for making a large number of the same type of products on the stream when working on order.

Below are the stages of assembly of a machine for bending a rod with a maximum section of 10x10 mm. The 0.5 kW / 1000 rpm motor is working at the limit of its capabilities. Performs 6 shaft revolutions per minute. The segments of the volute were turned from a round blank St.45 without heat treatment, 25 mm high and 20 mm thick. The snail is mounted on the shaft on bearings from the rear wheel of the motorcycle - 7204. The supporting roller is fixed rigidly in the groove. Pulleys are installed between the motor and the gearbox.

Below are the drawings of the snail segments.

Snail element 2

Snail element 3

The central element of the snail

For a more massive rod (from 12 mm), the engine power should be more than a kilowatt. The photos below show a machine with a 2.2 kW 1000 rpm motor giving an output on the shaft of about 10 rpm. This is already a machine for professional use. A used gearbox is used, the matrix is ​​cut from a workpiece 30 mm thick - the most time-consuming process.

For cold forging, you also need an anvil and a hammer. The forge is not needed, it is only required for hot forging.

Advice! Before starting work, draw a full-size sketch of the future structure. This will help you adjust the elements and not get confused during assembly.
