What are the factors that affect the springback of stamping parts

When stamping in a stamping plant, you will find that the stamped parts produced often have springback problems. This problem is often encountered in the production process of stamping parts, so what factors affect the springback of stamping parts? Precision summarizes years of experience to give you a specific analysis. 1. Stamping parts with different material properties have different shapes and strengths. From general materials to high-strength materials, different materials have different yield strengths. The higher the yield strength of the material, the more likely to have springback problems. 2. The thickness of the material In the whole forming process, the thickness of the material has a great influence on the bending performance. The greater the thickness of the material, the smaller the springback. This is due to the increase in the thickness of the material and the participation of plastic deformation. The material is improved, so the ductility is also improved in response to the deformation, and therefore, the resilience is reduced. 3. The shape of the stamping parts The springback of parts with different shapes is very different. The stamping parts with relatively complicated shapes generally require an additional process for shaping to avoid springback due to improper forming.
