Abstract：

The locking mount is one of the most complex bending parts. It is easy to crack in the corner during processes of punching-blanking, both sides flanging and bending. Thus, its forming quality cannot be met. If the processes of punching-blanking, flanging, bending and flanging are adopted, it will not produce cracking in the corner. The two processes of multi-step forming were numerically simulated by the finite element software, and the quality of forming parts was compared with each other. BHF, die gap and punching speed were chosen as factors in orthogonal test. After that the simulation analysis was carried on by finite element software. The optimal combination of process parameters was determined by choosing the thinning rate of parts as the evaluation standard. The process was validity by the experiment.
