【摘要】 利用应力分界圆的概念,分析冲压件复合变形时产生的质量问题比较方便、简便和有效。通过模具参数、冲压条件的调整来控制应力分界圆的位置可以有效地控制质量问题的产生,在生产实际中可以通过测量变形获得应力分界圆的位置。更多还原

【Abstract】 It is more convenient, simple and effective to analyze quality problem of compound deformation of sheet metal pressing parts by means of the concept of stress circle. The occurrence of quality problem may be effectively controlled by adjustmont of die parameter and pressing condition to control position of the stress circle, and by measurement of the deformation in practical production to obtain the position of stress circle.更多还原
