  stampingThe process is a metal processing method based on the plastic deformation of the metal. The mold and the stamping equipment are used to apply pressure to the sheet material to plastically deform or separate the sheet material, thereby obtaining parts having a certain shape, size and performance. (Stamping).
  The stamping forming process plays an important role in the automobile body manufacturing process, especially the large covering parts of the automobile body. Because of the complicated shape, large structural size, some space curved surfaces, and high surface quality requirements, the stamping processing method is used. These parts are made in a way that is unmatched by other processing methods. The cab of the truck, the front sheet metal parts, the cargo panel and the various body panels of the car and the various skeletons of the passenger car are almost all made by the stamping method.

Characteristics

(1) Stamping is a processing method with high production efficiency and low material consumption. The stamping process is suitable for the production of large batch parts, easy 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 no waste production, but even in some cases The corner material can also be fully utilized.
(2) The operation process is convenient, and the operator does not need a higher level of skill.
(3) The stamped parts generally do not need to be machined again, and have high dimensional accuracy.
(4) Stamping parts have good interchangeability. Stamping processing stability is good, the same batch of stamping parts. Can be used interchangeably without affecting assembly and product performance.
(5) Because the sheet metal for stamping parts is used as a material, its surface quality is good, which provides convenient conditions for subsequent surface treatment processes (such as electroplating and painting).
(6) Stamping processing can obtain parts with high strength, high rigidity and light weight.
(7) Stamping parts produced in batches with molds are inexpensive.
(8) Stamping can produce parts with complicated shapes that are difficult to machine by other metal processing methods.

Stamping process can be divided intoFour basic processes:

Punching: A stamping process (including punching, blanking, trimming, cutting, etc.) that separates the sheets.
Bending: A stamping process in which a sheet is bent into a certain angle and shape along a curved line.
Deep drawing: a stamping process in which a flat sheet material is turned into various open hollow parts, or the shape and size of the hollow part are further changed.
Partial forming: A stamping process (including flanging, bulging, leveling, and shaping processes, etc.) that changes the shape of a blank or stamping with local deformation of various properties.
