Benching is a technological process associated with metal processing. Many people do not know what a crimping machine is or how to use it correctly. When purchasing equipment, you need to study the characteristics and operating principle of the device.
Sealing machine
Design and principle of operation
The zig machine consists of several elements:
- lower, upper shaft;
- handle for rotating shafts (for manual machines);
- screw for adjustment;
- rollers with the help of which parts are processed;
- gears transmitting rotational force between moving shafts;
- housings made of impact-resistant materials;
- cast bed for stable holding of the machine.
Regardless of whether the installation is equipped with an electric drive or not, there are no significant changes in the design or operating process. Zigovka is carried out in several stages:
- The parts are fixed between movable rollers.
- The shafts are aligned to securely hold the workpiece.
- The operator begins to rotate the handle or starts the electric drive.
The workpiece begins to rotate behind the shaft. The depressions are formed under the pressure of the protrusions on the rollers.

Marking of produced rollers
The depth and shape of the seam depend on the choice of working rollers. How to use nozzles depending on their purpose:
| Marking | What can you do with these videos? | Application area |
| V | Shape the edges of parts, roll wire | For the production of insulating boxes and pipes |
| E, EV | Corrugate the edges of pipes to reduce the diameter | To create socket joints in ventilation and drains |
| S | Create stop and rigid ribs | For the production of various sheet metal parts |
| S.K. | Make wide rectangular ribs | For fixing rubber seals in round ventilation pipes |
| B.S., F. | Make double folding of vertical locks with selected flange height | For joining sheet metal workpieces, roofing work |
| B.C. | Bend the edges of flat elements | For beading rectangular duct parts and creating rounded plugs |
| BB | Bead the edges of the mortises | To create mortises of various shapes and vertical locks on different parts |
| K.B. | Besiege a vertical castle | For the manufacture of elements of pipelines for draining water and venting air |
| BD | Bead the edges of the parts | For creating long circular pipelines |
| Z.B., Z.A. | Roll the wire along the edge of the pipe | To increase the rigidity of thin metal pipes |
| K.A. | Connect round pipes followed by spot welding | For the production of air ducts and chimneys in small batches |
| AV | Seamlessly connect the mortises using the screw method | For the production of ventilation blanks |
| DIN 71550 | Make semicircular ribs | To create diameters on which a flexible hose is attached |
| M | Cut pipes across | For the production of any pipelines |
Some operations require additional parts. For example, cutting can only be carried out if the rollers are equipped with parallel roller pressure. To cut out rings you need a special holder. To bead the outer edges of round holes you will need a semicircular stop.

Varieties
Sealing machines are classified depending on various factors. By drive type:
- Manual. Simple designs that begin to work after applying physical effort. The position of the rollers is changed manually. Manual beveling is not used for working with thick metal.
- Electrical. In terms of power, these models are considered average. The shafts rotate thanks to an electric motor. Electromechanical creasing machines are more expensive than manual ones, but they can process sheets of large thickness.
- Hydraulic. Powerful equipment. A special feature of hydraulic machines is reliable clamping of the rollers. Disadvantage - large dimensions, large mass.
A separate classification relates to the size and weight of equipment. There are compact, portable models that are easy to transport. Large-sized machines have been developed for enterprises that are suitable for mass production.

DIY making
If you wish, you can assemble a manual zig machine with your own hands. To do this, it is enough to find a drawing, prepare materials, tools, and perform the work.
Sealing machine
Preparation
Before you start assembling a manual zigging machine, you need to prepare tools and consumables:
- drill with metal drills;
- a small grinder with discs;
- welding machine;
- two shafts;
- gears for transmitting force between shafts;
- metal corners, profiles, sheets for the manufacture of beds, frames, housings;
- fasteners;
- handle for rotating moving parts.
- screw for adjusting, pressing the shafts.
Assembly steps
When assembling equipment, you need to consider the following nuances:
- The lower shaft must be stationary, the upper one must move within a range of at least 12 mm.
- Side stops should be installed to prevent the shafts from moving to the side when working with workpieces.
- To transmit force, gears are used, which should not be less than 60 mm in diameter.
- Secure the shafts so that they can be changed during operation of the equipment.
- Welding equipment is used for the manufacture of frames, housings, and beds.
- To make the case, it is enough to use metal sheets with a thickness of no more than 5 mm.
The handle can be made from handles from any old machine. If commercial rollers are not suitable for the finished unit, you will have to create them yourself. For this you will need a lathe.
Electromechanical zig machines are more difficult to manufacture. To do this, you need an electric motor with a speed controller, a belt drive, and a control panel.
Questions and answers
What products can be made on crimping machines?
Buckets, deflectors, and funnels can be produced using crimping equipment. The machines allow you to roll thrust ridges, corrugate metal blanks, make drainage elbows, etc.
Are there any differences in the operating principle of manual and electric seaming machines?
There are no fundamental differences in the operation of manual and electrical equipment.
What machines can handle metal with a thickness of 3-4 mm?
Metal of this thickness can only be processed on electric or hydraulic industrial crimping machines.
What does roller overhang affect?
Regardless of the type of equipment drive, roller overhang affects its technical capabilities.
What type of crimping machines is best to use for roofing work?
In roofing work, it is better to use manual zig machines. They can be lifted directly onto the roof.
Exploitation
For home-made or purchased models of staking machines, there are a number of operating rules:
- Check the integrity of the rollers, gears, and the location of the shafts before starting work.
- Turn the handle several times without the workpiece to eliminate defects.
- Keep your hands as far away from the treatment area as possible. Do not wear long sleeves.
- Do not attempt to connect parts of large thickness. Excessive effort will lead to material damage and equipment failure.
- Do not overload the electric motor.
- Lubricate moving parts with machine oil at least twice a month.
- Check the accuracy of the workpiece alignment between the rollers.
Metal beading is a simple process that anyone can do.
Metal creasing machines are used to carry out various technological processes. With their help, you can connect metal pipes and increase the strength of individual parts. You can make a homemade hand loom for your home.
