摘要: High strength sheet metals have been widely applied in automobile and aerospace industries for their light weight. However, the formability forming behaviour of high remain still unclear. In this paper, we mainly focus research on springback via a servo press which can precisely control speeds, loads displacements. The shows that load, displacement multiple hit bending effectively, extension holding time cannot reduce amount dramatically speed almost does not affect springback.
