Research on Simulation of Bending Features Affecting Hot Forming Limits

High-strength steel plate hot stamping forming technology is one of the important means to improve the car's crash safety performance, but also to reduce the body parts thickness and the number of body parts to achieve a lightweight car body, subject to the automotive industry and related research institutions the widespread concern. Hot stamping forming technology refers to heating the high-strength steel plate to the hot stamping die to complete the stamping and in-mold quenching. The advantage of hot stamping forming technology is that it can effectively solve the forming defects of high-strength steel plate during cold stamping forming and the large amount of spring back, and the strength and hardness of hot stamping parts are also much higher than those of cold stamping parts. The strength can reach more than 1000MPa.
