The precautions for stamping parts are as follows:
From the perspective of stamping parts processing, the mechanical properties, surface quality and thickness tolerance of stamping materials should meet the following basic requirements: 1. The material used for punching should have sufficient plasticity and low hardness to improve punching fracture. Surface quality and dimensional accuracy. Among them, soft materials (such as brass) have good punching performance, hard materials (such as stainless steel, high carbon steel) have poor punching section quality, and brittle materials are prone to tearing during punching And so on. 2. The material used for bending should have sufficient plasticity, low yield strength and high elastic modulus. Among them, materials with good plasticity are not easy to bend and crack, and materials with lower yield strength and higher elastic modulus have smaller rebound. 3. The material used for deep drawing should have good plasticity, low yield strength and hardness, and large plate thickness directional coefficient. Among them, materials with high hardness are difficult to form by deep drawing; materials with small yield ratio or large thickness direction coefficient are easy to form by deep drawing. 4. The surface of the material should be smooth and clean, without scratches, scratches and other defects, so as not to affect the appearance quality of the product, and facilitate stamping processing, welding, spraying and other subsequent processing. 5. The thickness tolerance of the material should meet certain requirements: if the material of stamping parts thickness is out of tolerance, it will not only directly affect the stamping quality of the product and the life of the mold, but also produce waste or damage the mold.
