Metal stamping is a process in which stainless steel, iron, aluminum, copper and other plates and foreign materials are deformed or broken by punching machines and dies to achieve a certain shape and size. The processing of metal stamping parts includes blanking, bending, drawing, forming, finishing and other processes. So what are the requirements for metal stamping process?
1. When designing the structural shape of parts, hardware stamping shall adopt simple and reasonable surfaces and their combinations, and at the same time shall minimize the number of processed surfaces and the processing area as much as possible.
2. Choose a reasonable method of blank preparation in mechanical manufacturing, which can directly use profiles, casting, forging, stamping and welding, etc. The choice of blank is related to the specific production technical conditions and generally depends on the production batch, material properties and processing possibilities.
3. In order to facilitate the stamping deformation and the improvement of the product quality, the material should have good plasticity, small yield ratio, large thickness directivity, small plane directivity and small ratio of yield strength to elastic modulus. The separation process does not require materials with good plasticity, but materials with certain plasticity.
4. Specify appropriate manufacturing precision and surface roughness. The cost of metal stamping parts will increase with the improvement of precision, especially in the case of higher precision, this increase is extremely significant. Therefore, high precision should not be pursued without sufficient basis. Similarly, the surface roughness of metal stamping parts should also be properly specified according to the actual needs of the mating surface.
Metal stamping is suitable for products in various fields. With the development of science and technology, the process of metal stamping is constantly improving, and the technological requirements for metal stamping are also constantly improving.
