本文总结了影响板料成形性能的因素并指出相应改善方法 ,重点研究了压边圈形变对板料成形性能的影响 ,并指出考虑BH形变的BHF控制是压边力控制研究的方向。
This paper summarizes the factors which influence the sheet forming performance and points out the corresponding improvement methods. The influence of blank ring deformation on the sheet forming performance is mainly studied. It is pointed out that the BHF control considering BH deformation is the research direction of blank holder force control.
