The manufacture of automobile stamping parts is to use the pressure of press to punch metal or non-metal dies to form processing parts. The great feature of stamping parts is that they can not consume much material, and the processed parts after stamping have good rigidity and light weight. After plastic deformation, the metal structure can be greatly improved, so that the strength of stamping parts can be improved a lot.

1. Due to the small production batch, safety protection device must be installed in the stamping operation which can neither realize automation nor use safety stamping tools, so as to prevent injury accidents caused by operation errors. All kinds of protective devices have their own characteristics and use range. If they are not used properly, injury accidents will still occur.

2. Reform the process, mold and operation mode to realize the operation outside the manual mold.

3. Transform stamping parts to improve production safety and reliability.

A large number of cold stamping processes have been used in the production of automotive stamping parts, which are suitable for the needs of many varieties and large-scale production of automotive stamping parts industry. In medium and heavy-duty vehicles, most of the covering parts, such as body outer panel, and some load-bearing and supporting parts, such as frame, carriage and other auto parts are automobile stamping parts. The steel used for cold stamping is mainly steel plate and steel strip, accounting for 72.6% of the total steel consumption of the whole vehicle. The relationship between cold stamping materials and the production of automobile stamping parts is very close. The quality of materials not only determines the performance of products, but also directly affects the process design of automobile stamping parts process, and affects the quality, cost, service life and production organization of products. Therefore, reasonable selection of materials is one of the most important factors An important and complex task.

Automobile stamping parts are the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, which makes the sheet directly subject to the deformation force and deform in the die. Sheet metal, die and equipment are the three elements of stamping.

The bucket strength of automobile stamping parts, castings and forgings is thin, uniform, light and strong. The workpiece with reinforcing rib, rib, curl or flanging, which is difficult to be made by stamping, can be made to improve its rigidity. Because of rejecting the rough die, the precision of the workpiece can reach micron level, and the precision is high, the specification is consistent, and it can punch out the hole, the boss and so on.

In practical production, it is often used to test the stamping performance of materials, such as drawing performance test and bulging performance test, which are similar to the stamping process, in order to ensure the quality of finished products and high qualified rate.
