Stamping process

It is a metal processing method, which is based on the plastic deformation of metal, and uses molds and stamping equipment to exert pressure on the sheet to make the sheet produce plastic deformation or separation, so as to obtain parts (stamping parts) with certain shape, size and performance.

Stamping forming process plays an important role in the manufacturing process of automobile body, especially the large covering parts of automobile body. Because most of them have complex shape, large structural size, some are spatial curved surfaces, and high surface quality requirements, stamping processing method can not be compared with other processing methods. The cab of heavy-duty truck, front sheet metal parts, cargo board, various body covering parts of car and various frameworks of bus are almost all made by stamping.

Processing characteristics

(1) Stamping is a processing method with high production efficiency and low material consumption. Stamping process is applicable to the production of large quantities of parts and products, which is convenient to realize mechanization and automation and has high production efficiency. At the same time, stamping production can not only strive to achieve less waste and waste free production, but also make full use of leftover materials even in some cases.

(2) The operation process is convenient and does not require the operator to have a high level of skill.

(3) The stamped parts generally do not need to be machined and have high dimensional accuracy.

(4) Stamping parts have good interchangeability. The stability of stamping processing is good, and the same batch of stamping parts It can be used interchangeably without affecting assembly and product performance.

(5) Because the stamping parts are made of plates, their surface quality is good, which provides convenient conditions for subsequent surface treatment processes (such as electroplating and painting).

(6) Stamping can obtain parts with high strength, high stiffness and light weight.

(7) The cost of stamping parts produced in batch by die is low.

(8) Stamping can produce complex parts that are difficult to be processed by other metal processing methods.
