Abstract

With the rapid development of the automotive industry, body lightweighting has become a key way to improve the energy efficiency and safety of automobiles. The application of high-strength materials can effectively reduce the weight of automobiles, thus reducing fuel consumption and emissions. This study revolves around hot stamping integral door ring forming molds and processes, and explores the advantages of multi-part integrated (MPI) hot stamping technology, especially in the application of Laser weld blanks. By integrally cutting blanks and laser splicing welding technology, hot stamping of door rings not only improves the production efficiency, but also enhances the strength and stiffness of the body structure. The study shows that with the optimized mold design and process, the weight of the integral door ring is reduced by about 20% and the safety performance is guaranteed, which provides an effective solution for the lightweighting of future automobiles.
