Sheet metal processing technology is basically divided into twosheet metal fabrication company groups. The first group is non-standard sheet metal processing. This technology is usually used when forming, either by shearing machine, laser cutting machine, or flame cutting method or plasma cutting method. After forming, bending is required, which is usually produced with a bending machine. Then after welding, the folded corners are repaired by welders. After welding, the welding scar is polished smooth. After painting, it is finished in the drying box.

The second group of ways, for the standard pieces of sheet GPU minermetal products, this cultural products is because the enterprise production volume is relatively large, rely on the development of the above way to do, certainly can not reach this capacity, so teachers need to use punch press terrain stamping, stamping before the design of a corresponding mold for different product structure, the material into the punch press, the analysis of multiple stamping plastic, general plate bar ah, open can be continuous Mold, mold industry to produce products after the market, to their product quality vibration grinding, the product side of the burr to remove, and then students to study the plating process.

For stamping die to do sheet metal process, we will not say much here, because it involves the design of the mold, and this mold design he is some worthwhile experience. The design must be based on the rebound of the material and the corresponding bending coefficient, as well as the characteristics of the product and the material thickness of the product, which is an industry in itself. Because of its mass production and the impossibility of welding operations, it is necessary to design a die that allows them to be riveted together.

We are talking here mainly about non-standardized sheet metal production processes. After all, this can only be fully compatible with our equipment. Processes, which we have already briefly described in the first paragraph, we now come to the use of sheet metal.

In general, on equipment, we usually use sheet metal as a cover on the frame, one is used to cut off the direct contact between the mechanism and people, providing a safety guarantee for the operation of the equipment, and the other is to play a decorative role. If we expose all the working seats of the machine, it is difficult to take into account the appearance of the equipment, because its mechanisms are arranged according to their function in the working area. At this point we can make a cover to cover all the work pieces inside so that people can see the equipment.

The sheet metal cover also has such a system function designed to protect the technical equipment to carry out the internal some electrical components, we all know that the circuit above the equipment has an important, so to speak, electrical appliances inside the Plc, is through the brain of the equipment, our country must ensure its safety, stability and reliability to be used, which contains the equipment cost control work procedures, once the damage to the equipment, equivalent to become themselves a plant, so we need to be well protected to develop it.

Next, we will discuss the bending process of sheet metal, because the most important thing in the whole process is bending, because there is a change in the length of the material during bending, and this change in length is associated with a certain empirical value, we usually use the bending derivation and K-factor, K-factor is just a noun that is ultimately given by the empirical value.

Because this bending is a non-standard practice, but any non-standard, in some books and textbooks, it is impossible to find the relevant material to learn, we see that the metalworking material is still basically in a standard processing part.

How do we, as designers, determine this value when drawing? It is suggested that when designing sheet metal bending, we can consult the bending master on site and ask the master to bend the various materials used and the R angle of the bending tool, as well as the corresponding material thickness, and then make a table, which we put into the software.
