What are the basic requirements of the metal stamping process? We all know that metal stamping processing by punching machine, die for pressing and forging materials was a way of processing, with the features of convenient operation, high precision stamping, is easy to realize mechanization and automation and other advantages, is the most used way of processing, then what hardware stamping process is the basic requirement of the following to you:
The basic process requirements of metal stamping parts are as follows:
1, metal stamping parts used in the material, not only to meet the technical requirements of product design, but also should meet the requirements of the stamping process and stamping processing requirements (such as cutting, electroplating, welding, etc.).
2, metal stamping parts in the design of the structure of the shape of the parts, it is best to use a simple and reasonable structure of the surface (such as plane, cylindrical surface, spiral surface) and its combination, but also should try to make the minimum number of processing surface and processing area.
3, choose a reasonable method of blank preparation in mechanical manufacturing, can directly use profiles, casting, forging, stamping and welding, etc. The selection of blank is related to the specific technical conditions of production and generally depends on the production batch, material properties, and processing possibilities.
4, metal stamping forming performance requirements, for the forming process, to improve the quality of stamping deformation and parts, the material should have good plasticity, small flexural strength ratio, plate thickness directivity coefficient, plate plane directivity coefficient is small, the yield strength of the material and the ratio of elastic modulus is small. For the separation process, the material doesn't need to have very good plasticity, but it should have certain plasticity, the better the plasticity of the material, the more difficult it is to separate.
5, specify appropriate manufacturing accuracy and surface roughness parts processing costs. The processing cost of metal stamping parts will increase with the increase in accuracy, especially in the case of higher accuracy, this increase is very significant. Therefore, high accuracy should not be pursued without sufficient basis. Similarly, the surface roughness of metal stamping parts should also be based on the actual needs of the surface, and make appropriate provisions.
