Abstract：

For a highstrength steel reinforcement plate of an automobile A-pillar, four processes of bending, trimming and punching, flanging and punching, shaping and trimming were designed, and the whole process was simulated. The simulation results show that the parts have good formability, and the processes are reliable. Aiming at the problem of out-of-tolerance for part dimension caused by springback, blue-ray scanning and reverse modeling of parts for initial test were completed based on the blue-ray scanning reverse engineering technology. Compared with the initial design model of parts, the springback amount of parts was obtained, and the die surface compensation was carried out based on this result. Furthermore, the parts after springback compensation were detected, and the dimension tolerances of thirty measuring points for parts all met the design requirements. The test results show that the springback compensation method of stamping based on blue-ray scanning reverse engineering is feasible and effective, which can avoid repeated die testing and shorten the development cycle of die.
