The influence of materials on stamping parts processing

The main processes for stamping parts in stamping processing plants are punching, bending and stretching. These three processes have different requirements for stamping materials. Precision, dedicated to precision metal stamping for more than 10 years, and has accumulated rich experience in punching, bending, and drawing processing. Next, the author of precision will give you an analysis of the influence of different materials and these three stamping processes. 1. Blanking blanking stipulates that the raw materials should have sufficient plasticity to ensure that the material does not split during blanking. After the soft material is blanked, stamping parts with smooth cross-section and low slope can be obtained, and the cross-section of the hard metal stamping material is blanked. The unevenness is large, and the thick material is ductile material, which is very easy to cause tearing after punching; 2. The material that is bent and formed needs to have sufficient plasticity and lower strength limit; the plate with high plasticity should be It is not easy to crack when bending; materials with lower strength limit and lower elasticity molds have less resilience deformation after bending, and it is very easy to obtain bending parts with accurate dimensions; metal stamping parts with great ductility must be available when bending Large relative bending half-warp, otherwise the material is very easy to crack during the whole bending process; 3. The drawing processing technology of drawing materials not only stipulates that the deep layer of drawing is as small as possible, and the appearance is as simple as possible and rounded. It also stipulates that the material has good plasticity, otherwise it is very easy to cause the overall distortion of the stretched parts, partial wrinkles, and cracks in the stretched parts when severe; [Related Recommendations] Learn more: What are the methods for polishing the surface of stainless steel?
