Automobile stamping part is a kind of production technology, which can make the sheet metal directly subject to the deformation force and deform in the die with the help of the power of conventional or special stamping equipment, so as to obtain certain shape, size and performance of product parts. Sheet metal, die and equipment are the three elements of stamping. Stamping is a kind of metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), and also belongs to the material forming engineering technology.

Among the steel products of globegroup, 50-60% are made of plate, most of which are finished products after stamping. The car body, radiator, boiler drum, container shell, motor, electrical iron core silicon steel sheet, etc. are all stamping processing. There are also a large number of stamping parts in products such as instruments, household appliances, office machinery, and safekeeping utensils. Stamping is an efficient production measure. Compound die is adopted, and abnormal is multi position progressive die. It can complete multi-channel stamping technology operation on one press and complete automatic generation of materials. The production speed is fast, the rest time is long, the production cost is low, the collective can produce hundreds of pieces per minute, which is loved by many processing plants.

There are thin, uniform, light and strong characteristics between stamping parts and castings and forgings. Stamping can produce the workpiece with reinforcing rib, rib, curl or flanging which is difficult to make by this familiar hand diameter, so as to improve its rigidity. Due to rejecting the rough die, the precision of the workpiece can reach micron level, and the precision is high and the specification is consistent. It can punch holes, boss, etc. In order to ensure the quality of the products, such as the test and test, the quality of the products is similar to the test.

Stamping equipment in addition to thick plate forming with water press, usually take the stagnation press. Focusing on the modern high-speed multi station coagulating press, the equipment is equipped with decoiler, finished product collection, delivery, etc., as well as die library and quick die change placement. With the help of computer tube bundle, a passive stamping production line with high production rate can be formed. Under the condition of producing dozens or hundreds of stamping parts per minute, the stamping and discharging processes are completed in a short time, and personal, equipment and quality incidents often occur. Therefore, the safety production in stamping is a very important topic.
