First, the materials used for metal stamping parts should not only meet the technical requirements of product design, but also meet the requirements of stamping process and processing requirements after stamping , such as cutting, electroplating, welding, etc.
Second, when designing the structural shape of the metal stamping parts, it is best to use surfaces with simple and reasonable structures , such as planes, cylindrical surfaces, helical surfaces, and their combinations, and at the same time, the number of machined surfaces and the machining area should be minimized as much as possible.
Third, choose a reasonable method of blank preparation in mechanical manufacturing, which can directly use profiles, 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.
Fourth, the metal stamping performance requirements, for the forming process, in order to facilitate the stamping deformation and the improvement of the quality of the parts, the material should have good plasticity, small yield ratio, large plate thickness directional coefficient, and plate plane directional coefficient. Small, the ratio of yield strength to elastic modulus of the material is small. For the separation process, the material does not need to have good plasticity, but it should have a certain plasticity. The better the plasticity is, the more difficult it is to separate.
The last item specifies the processing cost of parts with appropriate manufacturing accuracy and surface roughness. The processing cost of stamping parts will increase with the improvement of precision, especially in the case of high precision, this increase is extremely significant. Therefore, high precision should not be pursued without sufficient grounds. In the same way, the surface roughness of metal stamping parts should also be properly specified according to the actual needs of the mating surface.
The processing technology of metal stamping parts is relatively complex. In order to ensure that the performance of stamping parts can meet the requirements of use, it is necessary to follow the corresponding process requirements to ensure the feasibility of production.
