摘　　要：法兰起皱、侧壁起皱和侧壁破裂是拉深成形的主要障碍,而合理控制压边力是防止起皱破裂的关键所在.在总结前期研究成果的基础上,结合拉深成形过程的特点,在成形三极限图中给出了圆锥形零件拉深成形的成功区域,并提出了获得最佳压边力控制规律的方法.这为圆锥形零件拉深成形中的模具设计、工艺参数的制定提供了依据,也为拉深智能化控制提供了保证.Blank wrinkling, side wall wrinkling and side wall rupture are the main obstacles in deep drawing. Controlling the BHF properly is the key where we can prevent the sheet metal from wrinkling and rupturing. Based on the earlier study, referring to the properties of deep drawing, the successful range in the forming tri-limit diagram of conical workpiece deep drawing and the way how to get the optimal BHF are presented, which is used to design the tooling, process parameters and is the basis of intellectual control in deep drawing.
