What machines can be made with your own hands. How to make homemade machines and fixtures for the home workshop

Drill and hand drill

Drill - DPR-52 engine, found in printers and hair dryers. hand drill- engine from car compressor, found in small heat guns and hair dryers.

Drill 2

Drill with interchangeable tips. Motor PIV MTM, from the tape drive of a vertical tape recorder, Bulgarian. The tachometer has been removed, and the flexible shaft of the drill is fixed in its place. Rotation from the axis of the motor is transmitted to the shaft with the help of a tightly worn spring. Fortified on the right axis diamond disc for dressing hogs. The whole mechanism is fixed in a holder with two degrees of freedom and easily rotates left and right, back and forth. The whole structure is suspended on the desktop at the top right, does not interfere with work. You can drown the motor in the table so that the drill hose comes out vertically upwards.

Engraving drill

Drill for engraving. The motor is 8000 rpm, the hose endures up to 10000. The motor and hose are connected by a spring worn on the axle.

Drill 1

Handle with pneumatic drill mechanism. The motor transmits rotation to the turbine, mounted through an adapter ring. The drill body already contains a planetary gear of approximately 3:1. A very powerful machine. Turning work was required: an adapter ring, a sleeve on the shaft, fitting a Morse taper to size 2a. It was difficult to install a high-current button.

Drill 2

Motor PIV 6 25/3A of Bulgarian production, operates from 5 to 40 V, from a vertical tape recorder/store. The tachometer (rear) is not used, but it balances the whole structure well. The button affects contact group from the iron, powerful and does not burn.

Cutting machine 1

The cutting machine 1 is made for non-reinforced abrasive discs with a thickness of 0.5-2 mm. Moveable table. The "brake" resistor is visible.

Cutting machine 2

Cutting machine 2 is made for non-reinforced abrasive discs with a thickness of 0.5-2 mm. Two working positions, from the top and bottom tables, so the motor is reversed. I cut boards, make keys, cut out frames for transformers.

Drilling machine 1

Drilling machine with 0.8 mm collet chuck. Made from the remains of a machine called "aluminum tag press". DPR-52 engine, I lengthened the axis only for the beauty of the whole structure. Drill stroke - 20 mm. A box for drills and an abrasive disc on the axis of the engine at the top for straightening drills are visible.

Boring machine 2

Drilling machine for chuck 2a. The stand is made of aluminum profile, it has a worm gear, with its help the carriage on bearings moves 80 mm under drills of different lengths. The handle shifts the motor itself by another 20 mm. At the top of the motor axis is an abrasive disc for finishing drills, protected by a frame. Bulgarian motor, from a tape recorder, a profile from a showcase, a worm from a water valve, bearings from a sliding table.

Boring machine 3

It's just a beautiful machine. The base is a frame for the linear movement of the heads of an 8-inch drive. On six bearings. The cartridge is fixed in the sleeve from the fan of the same drive. Worm gear - from a 5-inch floppy, round handle at the top. The last 20 mm of the drill stroke - with a separate handle. The transmission from the motor is a rubber belt, but a flat belt is better. I'll put a stronger motor.

The production of metal parts requires special equipment capable of creating a force that forms the shape of an object. Alternatively, you can purchase relatively inexpensive devices. However, it is not difficult to independently make almost any machine for cold forging with your own hands.

What is required for this we will consider in the course of our article.

Of course, if the budget allows, you can not particularly complicate your life and buy universal equipment for cold forging metal. Moreover, such a machine combines all the individual hand tools. But the rather small cost of such a workbench makes it inaccessible to many home workshops.

What do-it-yourself cold forging tools can be made and what to produce on them?

To establish your own metalworking workshop, the main six machines are quite enough: a bender, a twister, a flashlight, a volume, a snail, and a wave.

These homemade machines are capable of processing the main types of materials used in cold metalworking technology: squares, bars (with a cross section of up to 14 millimeters) and a steel strip, 3-6 mm thick with a width in the range of 25 millimeters. the same operation as the factory equipment: bending, twisting or pressing without loss of quality.

Also, on a home-made manual machine, it is quite possible to produce the main elements of cold forged products: curls, volutes, baskets required for further assembly. finished products. Moreover, the forging equipment itself is compact, it can be easily placed in a garage workshop.

Learning to work with a cold forging tool is very simple. It does not require special knowledge about the properties of the metal and its further processing (annealing, tempering or hardening). The training and production process is practically safe, the equipment and materials do not work with high temperatures, and the working mechanisms are very simple.

The only drawback in cold forging metal and working on manual equipment is the possibility of marriage if mistakes are made. But the main problem is that defects are very difficult to correct. Defective elements can be corrected only by heating the metal in a furnace or on a burner.

The easiest for self assembly there will be: snails, gnutiki and twisters. They do not require expensive tools. All you need is welding, a cutting tool, drawings with materials and a little understanding in mechanics.

So how to do homemade machines for cold forging with your own hands?

Assembly of different types of equipment

For the initial stage of arranging a cold metalworking workshop, three main devices will be required: a bender, a twister and a snail. What elements can be produced on them?

A bender is a device that greatly simplifies the bending of a part and the production of bends of any shape.

It easily handles rolled products in the form of steel strip and rod with dimensions of 12x12 millimeters. In addition to corner parts, the bender can create arc-shaped parts.

The twister serves to twist a long workpiece around its axis into a longitudinal spiral. In hot forging, there is a similar tool - a crank. The twister is similar to this device in its design. This is a frame on which a collar with a rotating head and a slider are fixed, which limits and fixes the desired length of the part. Parts twisted on such equipment are a frequent element used to assemble window grilles, fences, railings and other types of fences.

If you install additional devices in the form of a shaft on the twister, then it will be able to produce voluminous baskets.

The snail is perhaps the most famous manual cold forging machine. Volute and various parts twisted around the axis are produced on its conductor. The assembled device consists of a kind of frame (round / square), a conductor (spiral) and a roller with a manual drive in the form of a lever are fixed on it. By pressing the drive lever and feeding the workpiece, any type of spiral can be twisted without problems.

The main thing in the manufacture manual equipment for cold forging of metal - compliance with three basic principles:

The length of the lever drive is calculated so that sufficient force is applied to the metal.
It is best to make the components of the installations prefabricated or movable, then it will be possible to easily adjust the dimensions of the elements produced.
All parts of the conductors are made with a sufficient margin of safety, and the connections must be of high quality.

Observing such principles, it is quite feasible to manufacture normal metalworking equipment with excellent performance.

The listed three installations with the mechanism working manually, allow to make the majority of names of production without a metal warming up.

Gnutik assembly

This cold forging machine has a wide range of applications. With it, you can bend parts of any configuration. The device is quite simple, it consists of a base on which the rollers are mounted, a wedge (setting bend) and control levers. The machine itself can be made in a vertical or horizontal design.

It is easier to make a horizontal type on your own.

It is necessary to prepare a frame in which mounting holes are drilled for mounting the rollers, wedge and lever.
The wedge should move along the bed (controlled by pressing the lower lever). Its position should be interchangeable, so it will be possible to adjust the angle and steepness of the bend. To do this, it is better to make it on a screw thread, screwing in which changes the distance of the wedge.
The upper arm is used to shape the workpiece into an arc shape.

After watching the video, you can understand how such a machine works and the principle of its device

Making a snail

The photo shows the main parts of the snail cold forging fixture. The formation of the element occurs due to a special conductor, curled with a spiral (snail). This part, preferably, should be two-part. The manufacture of the machine is as follows.

A frame is prepared in a round or square shape. For its manufacture, it is better to use metal 5-6 mm.
Holes are drilled in the base for fastening the conductor (its two parts) and the working lever.
A rotating roller is mounted on the side, which will set the movement of the workpiece.
The lever must have sufficient strength, it can be made from an appropriate profile or pipe (with thick walls).
The conductor is made of thick metal, curved in a spiral. It has holes for mounting bolts.

Below are photos of the drawings of the conductor and the device itself.

For a more understandable principle of operation of such equipment, watch the video provided:

Made manual machines for do-it-yourself cold forging with this design are quite capable of bending bars and squares different section up to 14 millimeters.

It is worth remembering that a greater force on a thick workpiece can be created using a longer lever, so an additional extension for such a drive can be provided.

There are other variants of the snail. For example, with a drive in the form of a gate located in a horizontal plane. Schematic drawings of such a device are shown in the photo below.

How to make a twister

The twister (or torsion bar) has a horizontal arrangement of parts. It consists of a frame on which a knob with a rotating head is attached, and a slider that rigidly fixes the workpiece and regulates the length of the product.

First you need to prepare a workbench (table) where the device will be fixed.
The bed can be made from a strong I-beam or any other material that has sufficient strength. Its length is selected depending on the parameters of the processed workpieces.
A slider is made on the frame. Its lower part should move along the device and be fixed in the desired position. Bolt holes can be drilled for mounting. The part where the workpiece will be inserted can be made to fit its size ( through hole) or made from a vise.
A collar with a rotating head can also be made to fit a specific workpiece or use a chuck from lathe(small sizes)
The unit is mounted on the table so that the edge of the table does not interfere with turning the knob.

As in the case of a snail, the length of the lever determines the force that is applied to the metal being processed.

If to make additional mount for the shaft, then on such a torsion bar it will be possible to produce volumetric baskets by twisting a rod onto a template.

The principle of operation of the machine is shown in the video:

Having studied the information, you can also make devices such as a wave (wave-like elements), a flashlight (baskets) or a volumetric (volumetric elements with parts curved in different planes).

If possible, then some of these machines can be made electrically driven by installing an engine with the appropriate power for this.

What can you add to this material from your personal experience for the manufacture of equipment for cold forging? How problematic is it to make a cold forging machine with your own hands and what materials to use? Join the discussion in the comments to the article and share your best practices.

The master came up with a new design of the machine based on the engine washing machine, which is more functional than analogues. In the course of work and in the final design, several interesting solutions were applied.

For homemade you will need profile pipe, plywood sheet, cut water pipe, bearing, stud, pulleys. At first I wanted to install a 420 watt motor, but later changed it to a 300 watt motor, which is enough for this design with pulleys.
The frame is in the form of a parallelepiped.
The master decided to install a large diameter grinding disc - 45 cm, in order to increase the functionality of the machine.
This machine has more options.

A few comments.

Maybe I'm a fool, of course, but I don't understand at all why people use disc grinders, why not a belt grinder? At the plate, after all, different places the disc has different speeds of movement of the sandpaper, which is why the sandpaper is almost never used near the center, and vice versa near the edge, then again cut into a circle - loss of material, a lot of glue is used for gluing, etc. In a belt grinder, the speed is the same everywhere, both in the center and along the edges, it is more economical in terms of sandpaper consumption, in terms of glue consumption, and in terms of wear resistance it is much better. you can glue the tape at least 3 meters, even more. Unless the engine for tape is needed more powerful, but the benefit is undeniable.

super. one note, no need to weld the assembly with bearings. Welding current passes through the balls and separators, it can spark through them and the service life of the assembly is noticeably reduced. At least the return wire must be connected to the pipe itself, and not to the axle. Otherwise, handsome!

Looked with pleasure. Lots of smart ideas! I would have ordered the bearing housing from the turner, but then I cut the pipe, tightened it, welded it and everything is ready! Subscribed to the channel. Hope you get a lot.
And the video editing made me happy! Already tired of people explaining “twice two” for an hour!

Machine tools and fixtures from a simple drill

It is difficult to do without mechanization and automation, having only hand tools. However, the drill is universal tool that even when there are no machines in the workshop, with the help of simple fixtures it is possible to raise productivity and convenience of work on only one drill and save not only time, but also finances.
Watch 5 homemade products for a drill at once in a short overview video of the DaBRO video channel.
Recommended video.

Another DIY worth having in your home workshop if you have a drill and don't have a separate sander and polisher.

Drill holder

It is fixed on a workbench, like a meat grinder.

A drill with such a clamp works as a grinder or

polishing device.

Thank you for watching!

On the basis of a large spring turned machine

wonderful and simple idea to do the job with manual circular saw more convenient, safer, faster and more accurate. The master adapted a large spring. The solution is universal and suitable for grinders and other tools.
Made a platform for the machine.

Attached door hinge to the circular

Attached to the platform.

I set the guide for sawing at an angle of 90 degrees, but you can, if necessary, vary the angle.

Put the rack and securely fastened the spring.

This is what the finished installation looks like.

The spring works as a return mechanism.

The idea of the author of the video channel Mr. Make Deswal: https://www.youtube.com/watch?v=Z8Ol2Djo5KU

The idea of a simple clamp for a cutting machine sped up the work.

An interesting and very convenient clip for quick work on cutting machine for metal uses a master. Usually not very convenient clamps are used, with which it takes quite a long time to fix the part. Lost work time and energy. The clamp is installed on the platform of the machine. Dimensions of the device for clamping metal and other workpieces. The video will begin immediately with a demonstration of the operation of this device. It also shows how to make a machine and a fixture for it.

Reading time ≈ 5 minutes

If your hands grow from the right place, then it is only natural that your workshop will need some equipment for the workflow. One of them is the Snail cold forging machine, which is easy to assemble with your own hands if you have drawings and dimensions at hand, and photos of similar designs on the Internet confirm the ease of assembly.

Design "Snail"

This unit will greatly simplify the workflow. Also, with it you can change the metal beyond recognition and create products of extraordinary beauty and practicality.

Application and equipment features

Products created using forging technology often cost a lot of money, but look quite noble and expensive. They decorate estates, interior, used as a gate. Art style helps to make forging more refined and create the same product in different versions.

Forged products options

Few people know that forging is not only hot, but also cold. The second option is quite possible to easily use in any home environment. It is enough to create equipment suitable for this - a cold forging machine.

Initially, it is worth deciding on the type of cold forging. Often there is an opinion that stamping also applies here. But this is a slightly different process.

But cold forging can be attributed to two types of work.

Hardening is hardening, which is carried out thanks to numerous blows that have great power. This leads to a change in the structure of the metal and leads to the formation desired shape and sizes. It uses a hammer, the manufacture of which does not require much time and effort.
Bending - the structure of the metal and its characteristic indicators cannot be changed. To engage in this type of forging, you need to build a machine.

The latter option is distinguished by its simplicity, if we talk about technological process. Next, consider for cold forging with your own hands, drawings and videos of which you will find below.

Video: cold forging machine

Self-manufacturing of the device

If you are determined to create this fixture in your home workshop, then you need to initially prepare a drawing. The ideal option will use a template sample, which has a maximum of options for creating various forms and figures. When you have such blanks available, then creating a machine with a sufficient number of removable nozzles will allow you to further create intricate and diverse patterns and all kinds of metal monograms.

Cold forging machine

When you are building home machine then follow a certain sequence of work so that the result is as ideal as possible.

Take a sheet of metal. Templates should be placed on it with the expectation of manufacturing. Indeed, during operation, the raw material itself from the nozzles can move if there is not enough space. It can be problematic to work with very small indents of templates from each other.
To make changing nozzles easy and simple, form a slot in the shape of a rectangle. Here you will place interchangeable nozzles, which are pre-attached to a rectangular plate. You will fix such plates with the help of bolts of a suitable size.
Templates can be made elementary or complex. It is possible to have a pattern with a single swirl or an element with swirls in different sides. It all depends on your skill.

Blanks for the machine

The main thing is to use the most durable material to secure the parts that move apart.

Drawing machine snail

No special tool is needed, the creation of a snail machine is quite simple. To make it, follow these steps.

Rack assembly. She happens to be supporting element throughout the structure. For its manufacture, identical cuts of pipes are taken, which are connected using joints. From the side, the stand is somewhat reminiscent of a stool. Via welding machine it is necessary to connect all parts of the rack.

2. Sheets of metal must be cut in accordance with the drawings. As a result, you will get 4 equilateral triangles and circles with equal diameters.

3. Triangles are welded to the bottom of the support to form a pyramid. The base (widest area) is welded to the center of the cut circle.

4. Drill holes for the bolts. With their help, in a horizontal position, attach to a circle with a welded part of the bar (four pieces).

5. Formation of the handle. To do this, you need two bars with different lengths (correlate the length with the dimensions of the circle itself) in the following ratio:

the first one corresponds to the diameter of the circle;
the second is slightly longer than the first.

6. The first rod is bent at an angle of 300, then the second rod is welded to the first one. An additional rod is attached to the bottom. It is important not to forget to insert a jumper between both rods (attach a lever to it using a welding machine). The lever will provide movement in the direction of the formation of the bars.

7. The bearing is attached to the lever and the cut at the bottom, which increases its variability. The coil of metal will be fastened with a cut at the top (for this it is placed horizontally and allows you to bend the metal). From the side of the bottom of the segment with a free end, a hole must be made that corresponds to the cross section of the pipe.

8. The final step is to attach the handle to the "pyramidal" part of the structure. The connection is made using a nut with a large diameter. Before attaching, a round piece is welded to it to attach the stencil.

Built machine snail

Therefore, you can assemble a “snail” cold forging machine according to the drawing and size with your own hands as in the photo in a home workshop without investing huge finances. After that, you will be able to create real metal masterpieces.
