What is stamping process?

Stamping process plays an important role in automobile manufacturing process, especially the large covering of automobile body
Because most of the complex shape, structure size, some or space curved surface, and surface quality requirements
High, so using stamping processing method to produce these parts is incomparable with other processing methods.
Cab, front sheet metal parts, cargo box plate of heavy trucks and various body covers and passenger cars
All kinds of skeleton, etc., are almost all made by stamping processing method.
Its features:
(1) stamping is a processing method with high production efficiency and low material consumption. Stamping process is suitable for larger
Batch parts production, easy to realize mechanization and automation, with higher production efficiency
When, stamping production can not only strive to achieve less waste and no waste production, but also even in some cases
There is spare material, also can make full use of.
(2) The operation process is convenient and does not require the operator to have a high level of skills.
(3) Stamping parts generally do not need to be machined, with high dimensional accuracy.
(4) The stamping parts have good interchangeability. Stamping processing stability is good, the same batch of stamping parts. To each other
For exchange use, assembly and product performance will not be affected.
(5) Because the stamping parts use sheet metal as material, its surface quality is good, for the subsequent surface treatment process
(such as electroplating, painting) provides convenient conditions.
(6) Stamping processing can obtain high strength, stiffness and light weight parts.
(7) The cost of stamping parts produced in batches by molds is low.
(8) Stamping can produce parts with complex shapes that are difficult to be processed by other metal processing methods.
basic steps:
Separate sheet metal stamping process (including punching, blanking, trimming, cutting, etc.).
Stamping process in which sheet metal is bent to a certain Angle and shape along a bending line.
flat sheet into a variety of open hollow parts, or the shape of the hollow parts, size for further change
Variable stamping process.
Local forming: A stamping process in which the shape of a blank or stamping part is changed by local deformation of various properties
(including flanging, bulging, leveling and shaping process, etc
