Abstract：

For a vehicle door anti-collision beam of high strength steel 950DL_CR produced by Baosteel, the stamping process of whole process simulation and its springback compensation were emphatically studied. First of all, the manufacturability of vehicle door anti-collision beam of high-strength steel 950DL_CR were analyzed scientifically, and the whole stamping process was simulated by finite element software AutoForm. Then, the stamping formability and springback result of the final product were analyzed, and the compensation strategy was demonstrated for the springback problem in the stamping process. Furthermore, the corresponding compensation treatment for the die face of stamping die for vehicle door anti-collision beam was conducted by the Global Shape Modelling (GSM) module of ThinkDesign, and the springback of actual stamping parts were detected by the three-coordinate measuring instrument. The results show that the stamping parts obtained after compensation can meet the requirements of springback tolerance range in the actual production, so the strategy and means of compensation achieve the expected goal.
