| 摘 要： | 圆锥形零件极限变形程度可用极限拉深系数［ｍｚｄ］＝［ｄ２／Ｄ０］来表示。根据圆锥形零件与圆筒形零件的内在联系，经力学分析得出了便于实用的圆锥形零件极限拉深系数［ｍｚｄ］的计算表达式，并由此给出了用［ｍｚｄ］所表示的成形极限曲线和第一次拉深时的极限拉深系数。经实验验证表明所确定的成形极限是准确和可靠的。

| Abstract: | The limit deformation degree of conical parts is expressed by the limiting drawing factor m zd ]=d 2/D 0] Based on the intenal relation between conical parts and cylindrical components,the practical calculation expression of m zd ] is derived by mechanical analysis,and the forming limit curves expressed by m zd ] and the limiting drawing factor in the first drawing are derived It is shown that the forming limit determined in this paper is accurate and reliable by experimental verification. |
