Shaped Part

To research the key factor that affect on material characteristic of hot stamping, this paper studied the spring-back problem of hot forming of the ultra-high strength steel, "U" shaped part by using the combination method of numerical simulation and experimental verification. By obtaining the data of BR1500 HS isothermal tensile test, it established a "U" shaped part of thermal-mechanical coupled model which is based on ABAQUS to analyze the influences of forming speed and holding time on the forming properties. Simulation analysis showed that: When the forming speed of sheet metal is faster than 35mm/s, the rebound value is small, and further increase has no significant effect on the rebound; after holding 6s, the temperature quenching would become stable. The results verify the reliability of the finite element model. Also the study has provided a theoretical basis for determining the process parameters of the type of steel hot forming.
