Springback of Hot Stamping and Die Quenching for Ultrahigh-Strength Boron Steel

摘要：

Hot bending and die quenching for U-shaped parts with ultra-high strength boron steel were experimented and simulated to study die geometric parameters’ effect on springback and its mechanism. The results indicate that through the hot contact bending and die quenching, bending parts with higher strength than that of cold stamping can be achieved, whose tensile strength can reach 1500MPa. The springback angle of hot bending part increases with the increasing of the die radius, the gap between the punch and die. Springback is mainly negative caused by different cooling rate and the impact of the thermal restoring moments. This provides a basis for the control of the hot stamping process applied in complicated shape parts’ production.
