Metal stamping processing, what are the requirements for processing technology?
Metal stamping processing is a processing technology that uses high-speed punches and abrasive tools to deform or break stainless steel plates, iron, aluminum, copper and other materials of the opposite sex to achieve a certain shape and specifications. Metal stamping parts processing includes cold stamping, bending, deep drawing, forming, finishing and other technological processes. So what are the requirements for metal stamping processing?
Metal stamping processing
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
Hardware processing is now applicable to various fields, ranging from daily necessities in life to large manufacturing industries. Of course, each type of processed part in each industry has different processing techniques and processing requirements.
