The basic process requirements of precision stamping parts [hardware]

Precision stamping parts are widely used in both industrial production and daily life. Metal stamping is a processing method in which materials are stamped and forged by stamping machines and molds. It has convenient operation, high stamping accuracy, and easy mechanization. The advantages of automation and automation are the most widely used processing methods at present. Now Panda will introduce the basic process requirements of metal stamping parts. 1. When designing the structure and shape of precision stamping parts, as far as possible, use simple and reasonable surfaces (such as planes, cylindrical surfaces, spiral surfaces) and combinations thereof, and at the same time, try to minimize the number of processed surfaces and the processing area. 2. The materials used for precision stamping parts must not only meet the technical requirements of product design, but also meet the requirements of the stamping process and the processing requirements after stamping (such as cutting, electroplating, welding, etc.). 3. The requirements of precision stamping performance. 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 thickness directivity coefficient, and small planar directivity coefficient , The ratio of the yield strength of the material to the modulus of elasticity is small. For the separation process, the material does not need to have good plasticity, but it should have a certain degree of plasticity. The better the plasticity, the more difficult it is to separate. 4. 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. 5. Specify the processing cost of parts with appropriate manufacturing accuracy and surface roughness. The processing cost of precision stamping parts will increase with the improvement of precision, especially in the case of high precision, this increase is extremely obvious. Therefore, when there is no sufficient basis, high accuracy should not be pursued. In the same way, the surface roughness of metal stamping parts should also be appropriately specified according to the actual needs of the mating surface. The above content is about the basic process requirements of precision stamping parts, I believe everyone has already understood. The processing technology of precision stamping parts is relatively complicated. In order to ensure that the precision stamping parts can meet the requirements of use, it is necessary to follow the above process requirements to ensure the feasibility of production.
