- Abstract
In this study, the high strength steel DH780 produced by Shougang Group was used to form a traditional part B-pillar. The effect of process parameters, namely blank holder force and friction coefficient on the formability was analyzed. The decrease of BHF and friction coefficient can increase the formability. And the optimization methods were introduced and applied to form a qualified part. Three optimization methods were employed, namely optimizing the critical surface of die, modifying the geometric parameter of drawbead, and changing the corner size near the critical area. The qualified part can be formed with the proper optimization.
