Keep in mind the taboos of precision metal stamping parts

As we all know, to make a precision metal stamping part, one of the key factors is the material. The quality of the material directly affects the production of stamping parts. What should we pay attention to when selecting materials? The punching process is usually not suitable for brittle and hard materials: the more brittle the material, the easier it is to tear during punching; the material with good elasticity and high flow limit can get a good section and punch out smooth and small inclination sections. ; High elastic materials should not be used in the bending process. The greater the elasticity of the material, the greater the rebound of the formed part to its original state after bending, resulting in the workpiece not reaching the predetermined shape, requiring multiple trial mold repairs; the material for the forming process should be It has sufficient plasticity, lower yield point and higher elastic modulus. The former guarantees no cracking, and the latter makes it easy for the workpiece to reach an accurate shape; drawing parts should not be made of materials with poor toughness, because low plastic materials have a small degree of deformation , It is necessary to increase the number of deep drawing processes and intermediate annealing, and deep drawing should use materials with strong toughness, low yield point and good stability; cold stamping processes should not use materials with high mechanical strength and low plasticity to increase cracks caused by deformation resistance. The material is required to have high plasticity and low yield point. [Related recommendation] Learn more: How much do you know about new energy automobile stamping parts?
