摘要
压边力(BHF)是薄板拉深成形过程中的一个重要工艺参数,本文应用能量理论分析法建立了应变强度εi的计算模型,该模型比传统模型更接近于实际,且基于εi建立的压边力模型在成形极限允许范围内能有效地抑制起皱,对提高拉深件质量有着重要意义。
Blanking Holder Force(BHF)is one of the important parameters of sheet drawing process.The means of energy theory analysis have been used to establish mathematical model of strain strength which is more practi-cal than traditional model,and the BHF model established by the strain strength from calculation can effectively pre-vent the wrinkling within the forming limitation,which has good effect on promoting the quality of drawing parts.
