板料冲压成形中的主要缺陷为撕裂、起皱 ,而引起这些缺陷的因素又多种多样 ,如模具结构参数、板料材料物理性质、摩擦与润滑、冲压设备的选择、压边圈的设置等。要达到正确分析各参数的影响 ,必然要借助于弹塑性有限元理论和计算机技术。本文综合国外最近几年的研究结果 ,分析压边力这一参数对撕裂和起皱的影响规律 ,以及为此而采取的措施。 The main flaws in sheet metal stamping are tearing, wrinkling, and many other factors that cause these defects, such as the structural parameters of the mold, the physical properties of the sheet material, friction and lubrication, the choice of stamping equipment, Settings and so on. To achieve the correct analysis of the impact of various parameters, must rely on the elastoplastic finite element theory and computer technology. In this paper, the research results of foreign countries in recent years, the impact of blank holder force on tearing and wrinkling of the law, as well as the measures taken to achieve this.
