In detail: do-it-yourself punch for body repair from a real master for the site my.housecope.com.
Hole puncher is a popular tool in any body shop. It is often used when replacing parts, such as new car roofs, where careful drilling is required. It is much easier to make such holes with a hole punch than with a conventional drill. With its help, you can easily and accurately punch holes according to previously made markings. The hole punch easily handles sheet metal up to one millimeter thick, so it is perfect for car repairs. Moreover, using it is no more difficult than using ordinary pliers. The hole punch is made of high quality metal alloy, and its simple mechanism consists of a strong spring and stem. A quality hole punch should easily handle thick sheet metal.
Kromkogib - this is another indispensable tool in the arsenal of any auto repairman. The use of both tools produces excellent results when welding two thin sheets of body iron. In order to ensure the most durable connection, the method of electric rivets is used. This method is considered more reliable due to the fact that the joint has increased elasticity and is not prone to cracking. However, for aesthetic reasons, some parts, such as repair inserts, have to be butt welded. Kromkogib provides the ability to weld such overlapping parts, so that such a connection can be easily hidden with a small amount of putty.

A tool as simple as an edge bend can be useful in many sheet metal working situations. There are many models of such a device on the modern market, but if you wish, you can make it yourself.
Cromcibs can be used to form rather complex profile elements
A bending machine or the simplest hand tool designed for bending edges is widely used in many fields. Kromkogib allows, in particular, to make elements of air ducts from thin sheet metal, to prepare the edges of workpieces for their joining by means of welding. Car repair (bodywork) is another area of application for such tools and equipment.
Kromkogib is also actively used in construction and when performing repair work around the house. Using such a tool, folded joints of thin sheet metal elements are formed and even products of various configurations are made.
Bending the end of the downspout on an electromechanical bending machine
If we talk about the principle by which the edge bend acts, then it is quite simple.To bend the edge of a thin sheet product, the edge bending scale is set to the required processing width, then the edge of the workpiece is placed between the working rollers of the device and, moving the device, bending is performed.
The simplest in design of the bending devices on the market are manual roller-type devices. All manipulations with such edging bends are carried out using the handle with which they are equipped, and the main work on deforming the edge of the metal blank is performed by the rollers. The width of the bending performed with such a device is adjusted by means of a special limiter installed on the guides of the device.
Compact hand-held edging machines can be used directly on site
The high mobility of the crimping machine, which can be operated even at high-rise buildings, is ensured not only by its compact dimensions, but also by its low weight, which is about 2 kg. Using a manual hemming tool, you can bend the edge of a metal workpiece at an angle of up to 90 °, while the thickness of the metal from which it is made cannot exceed 0.8 mm.
With the help of an edge bending machine, bends of any length can be performed, and their width can be in the range of 0.5–20 cm. As can be seen from the technical characteristics of such a device, its capabilities are quite limited, therefore it is advisable to use it only for solving simple technological problems. More productive and functional is the bending machine equipped with a hydraulic drive. The operator working on such equipment does not need to exert significant physical effort in order to bend the edge of the metal workpiece. Due to the high power that such a device is characterized by, it can be used for processing sheet metal workpieces even of considerable thickness.

The hydraulic bending machine, depending on the dimensions, can be stationary or mobile. It is the hydraulic drive that is most often equipped with such equipment, which has another name - "edge-bending press".
The bending machine can also be equipped with an electromechanical drive. With the help of this equipment, it is possible to produce folds of various types and even to carry out upsetting of the fold seam, if the equipment of the machine allows this.
Edging or trimming on a roller machine occurs using replaceable rollers, on which the shape of the bend depends
Pneumatically operated edge bending machines are very popular. The working bodies of such a machine, operating on the principle of a "swing beam", due to the use of a pneumatic drive, allow to exert significant pressure on the workpiece being processed, the value of which can reach 6.2 bar. Meanwhile, such an edge-bending machine can be used for processing blanks made of sheet metal, the thickness of which does not exceed 1.2 mm, while the width of the processed edge cannot be more than 12 mm. Having decided to use serial equipment of this category or make a pneumatic machine with your own hands, you should keep in mind that for the full operation of such a device, it is necessary to ensure an air flow rate of 113 l / min.
