Cold forging is impossible without special forging equipment. Let's look at the types of devices and the figures that can be obtained with their help. We have prepared drawings and thematic videos for you. We will also consider the sequence of making a cold forging machine with your own hands.
If you are just going to organize a cold forging workshop and want to avoid large expenses, then self-production machines and devices will help you create your own small business without excessive costs.
Basic devices and machines
Cold forging machines are mainly designed for arc or angle bending, as well as twisting. They can be manual or electrically driven.
The main types of machines and devices for cold forging:
- Gnutik
- Twister
- Snail
- globe
- Wave
- Flashlight
Device "Gnutik"
Purchased or made independently, the “Gnutik” is a universal device that allows you to obtain an arc or angle from a rod. It consists of a base with a slider, on which a stop with an angle (90° or another as necessary) and two cylindrical fixed stops are fixed. By moving the slider and the angle stop, the rod bends at an angle. To obtain an arc, a third cylinder is provided, rotating on the side opposite to the angle stop.
The device can be made on a horizontal or vertical platform.

This is what a homemade “Gnutik” looks like:
Twister device
“Twister” is a tool for twisting rods, mostly square, along the longitudinal axis. This simple device can be manual or electric. Operating principle: both ends of the rod are secured, then one fastening begins to rotate, twisting the metal to the required shape.

Device "Snail"
The Snail Tool is designed to create curls (or spirals) and “currencies” (S-shaped pieces). There are various designs.
One of the design options: 1 - snail ploughshare; 2 - base of the machine; 3 — pressure roller; 4 — lever for controlling the pressure roller; 5 — fastening the base; 6 — finger for fixing the plowshares; 7 — groove for the pressure roller; 8 — control lever axis; 9 — spring for pressing the roller; 10 — clamp for the workpiece; 11 — leading ploughshare of the snail; 12 — main axis; 13 — levers
The result should be something like this:
Another one lightweight design to bend rolled products with a cross-section up to 12 mm:
1 - cochlear segment; 2 - eccentric; 3 - handle; 4 - base; 5 — guide runners; 6 - axis; 7 - slider; 8 — axle nut; 9 — roller mounting axis; 10 - roller; 11 — drive axis; 12 — eccentric guide; 13 - central segment of the cochlea; 14 — eccentric wing; 15 — main leg; 16 — connecting pin of cochlea segments; 17 — adjustment screw; 18 - connecting ear of cochlear segments
Often the “Snail” device is made on a support, especially if you need to bend thick rolled products.
Several useful videos on homemade machines"Snails."

We will talk more about such designs below.
"Globe" device
Such a device is similar in appearance to a school protractor and is designed for making 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 its entire length according to the template. The principle of operation is somewhat similar to the operation of a canning machine.

Using exclusively muscular strength, arc large diameter can be made on a template screwed or welded to a workbench. It is good for bending strips, thin-walled pipes, etc.
Sample
Device "Wave"
You can produce wavy products from a round, square, hexagonal cross-section or tube using the “Wave” device. The deformation of the workpiece occurs between vertical rolls by scrolling.

Flashlight device
This machine produces blanks for “Lanterns” or “Pine Cones” elements, which can consist of 4, 6, 8 or more rods. According to 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 of the “Clamp” element
The cold forging element “Clamp” is designed to fix other structural elements together.
The device for bending the “Clamp” can be made according to the attached drawings.
Devices for making crow's feet
“Crow's foot” - flattening with the application of beautiful notches at the ends of the workpieces to make the structure more elegant or to reduce the thickness for various joints.
The ends of the elements are decorated with “houndstooth”
This operation can be performed using a machine with a die or fixture and a heavy forging hammer on an anvil. We provide both options in the form of videos.

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 production large quantity similar products on the production line when working to order.
Below are the stages of assembling a machine for bending a rod with a maximum cross-section of 10x10 mm. The 0.5 kW/1000 rpm engine operates at the limit of its capabilities. Performs 6 shaft revolutions per minute. The snail segments are machined from a round blank St.45 without heat treatment, 25 mm high and 20 mm thick. The volute is mounted on a shaft on bearings from the rear wheel of a motorcycle - 7204. The support roller is firmly fixed in the groove. Pulleys are installed between the engine and the gearbox.
Below are drawings of the cochlea segments.

For a more massive rod (from 12 mm), the motor power should be more than a kilowatt. The photographs below show a machine with a 2.2 kW, 1000 rpm motor, giving a shaft output of about 10 rpm. This is already a machine for professional use. A used gearbox was used, the matrix was cut from a 30 mm thick workpiece - the most labor-intensive process.
For cold forging you will also need an anvil and a hammer. A forge is not needed, it is only required for hot forging.
Advice! Before starting work, draw a sketch future design V life size. This will help you adjust the elements and not get confused during assembly.

Some home craftsmen make hand-held equipment for cold forging themselves. Using the drawings provided on the Internet, you can quite easily assemble the “Snail” machine.
Required tools and metal parts:
First of all, you need to draw a drawing of a spiral with three turns on a sheet of paper. After this, you need to check the dimensions so that a reinforced rod with a diameter of 10 mm fits into the thread. Now you can start making the machine.
- From steel sheet The grinder cuts out plates: 130x130 mm and 100x100 mm.
- Next, the sections of three steel strips and a three-centimeter rod are sanded with emery.
- Using a template, the steel strips are bent using pliers to form three spirals of different lengths.
- All elements of the machine are welded according to the diagram.
- A steel pipe is welded at the bottom center of the tool.
Welding work must be performed with high quality, since the service life of the machine depends on it.
