As the main material of automobile steel, the high strength steel plate is prone to crack, wrinkle and springback in the process of stamping. For an automobile front member rear part of CR380LA high strength steel plate produced by Baosteel, the materials and structural characteristics of parts were analyzed, and the stamping process scheme was determined as blanking, drawing, trimming+side piercing+flanging, shaping+side shaping. Then, the simulation of springback in the whole process of parts was studied by software Autoform, and the springback after part forming was predicted. According to the springback prediction results, the springback geometric compensation of drawing die surface on both side walls of part was achieved by the fold-in compensation design strategy. The results of simulation for springback after the die surface compensation and the actual production test show that the springback of part is decreased by 80% and controlled effectively, and the simulation of springback in the whole process and the die surface compensation of part are correct and reasonable to guarantee the forming quality and the dimension precision of part, which provides useful guidance for the forming process design and the die surface compensation of springback for the similar parts.
