What are the requirements for metal stamping process?

Metal stamping is a process that uses punches and molds to deform or break stainless steel, iron, aluminum, copper and other plates and other materials to achieve a certain shape and size. The processing of metal stamping parts includes processes such as punching, bending, deep drawing, forming, and finishing. So what are the requirements of the metal stamping process?

1. When designing the structure and shape of parts, metal stamping processing adopts simple and reasonable surfaces and combinations. At the same time, it should try to minimize the number of processed surfaces and the smallest processing area.

2. Choose a reasonable method of blank preparation in mechanical manufacturing, which can directly use profile, casting, forging, stamping and welding. The selection of the 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 improvement of stamping deformation and the quality of parts, the metal stamping processing should have good plasticity, small yield ratio, large plate thickness directivity coefficient, small plate plane directivity coefficient, yield strength and elastic modulus of the material. The ratio of the amount is small. The separation process does not require materials with good plasticity, but materials with certain plasticity.

4. Specify appropriate manufacturing accuracy and surface roughness. The cost of metal stamping parts will increase with the improvement of accuracy, especially in the case of high accuracy, this increase is extremely significant. Therefore, high accuracy should not be pursued without sufficient evidence. Similarly, the surface roughness of metal stamping parts should also be appropriately specified according to the actual needs of the mating surface.

Metal stamping processing is suitable for products in various fields. With the development of science and technology, the process of metal stamping processing is constantly improving, and the process requirements for metal stamping processing are also constantly improving.
