What are the basic requirements for various stamping parts, stamping parts, and metal products for stamping parts?

Basic requirements for stamping materials:

From the point of view of stamping processing, the mechanical properties, surface quality and thickness tolerance of stamping materials should meet the following basic requirements:

1. The material used for blanking should have sufficient plasticity and low hardness to improve the quality and dimensional accuracy of the punched section. Among them, the blanking performance of the soft material is good, and the punching section quality of the hard material (such as stainless steel and high carbon steel) is poor, and the brittle material is prone to tearing during punching.

2. The material used for bending should have sufficient plasticity, low yield strength, and high modulus of elasticity. Among them, the plastic material is not easy to be bent, and the material with lower yield strength and higher modulus of elasticity has less rebound.

3. The material used for drawing should have good plasticity, low yield strength and hardness, and large plate thickness directivity coefficient. Among them, a material having a high hardness is difficult to be drawn deep; a material having a small yield ratio or a large directivity coefficient of a plate thickness is easily formed by drawing.

4, the surface of the material should be smooth and smooth, no scratches, scratches and other defects, so as not to affect the appearance quality of the product, and facilitate the subsequent processing of stamping processing and welding, spraying. 5, the material thickness tolerance should meet certain requirements: If the material thickness is too poor, not only directly affects the product's stamping quality and mold life, and even produces waste or damage the mold.
