Improvement of stamping process for automobile parts;

1. When designing the structural shape of automobile stamping parts, it is best to adopt simple and reasonable surfaces and their combinations, and at the same time minimize the number and area of machined surfaces.

2. The materials used for automobile stamping parts should not only meet the technical requirements of product design, but also meet the requirements of stamping process and processing requirements such as cutting, electroplating and cleaning after stamping.

3. Requirements of automobile stamping formability For the forming process, in order to facilitate stamping deformation and improve the quality of parts, the material should have good plasticity, small yield ratio, large plate thickness direction coefficient, small plate plane direction coefficient and small ratio of yield strength to elastic modulus. For the separation process, the material does not have to have good plasticity, but it must have certain plasticity. The better the plasticity, the harder it is to separate.

4. Choose a reasonable blank preparation method in mechanical manufacturing, which can directly use profiles, casting, forging, stamping and welding. The selection of blank is related to the specific production technical conditions, and generally depends on the production batch, material properties and processing possibility.

5, the provisions of the appropriate manufacturing accuracy and surface roughness of parts processing costs. The processing cost of metal stamping parts will increase with the improvement of precision, so the surface roughness of metal stamping parts should also be properly specified according to the actual needs of the mating surface.

6. The stamping oil used in the processing of automobile parts should meet the technological requirements, and the special stamping oil with excellent performance can significantly improve the processing environment and improve the workpiece accuracy.

Stamping is a process of deforming or breaking stainless steel, iron, aluminum, copper and other plates and foreign bodies with punches and dies to reach a certain shape and size. The stamping process of automobile parts usually uses plates, thin-walled tubes and thin profiles as raw materials, which has the advantages of mechanization and automation.
