用实验研究的方法分析了锥形件冲压成形过程中悬空侧壁的外凸内凹曲面。用力的平衡方程给出了悬空侧壁的应力分布规律。并对此规律进行了分析和研究。对进一步揭示圆锥形件冲压成形机理。确定其破裂和起皱（内皱）临界条件，进而实现成形过程的智能化控制具有重要的意义。 The convex concave surface of the dangling side wall during the stamping process of conical parts was analyzed by the experimental method. The force balance equation gives the stress distribution of the suspended wall. And this law was analyzed and studied. To further reveal the conical stamping forming mechanism. Determine the critical conditions of rupture and creasing (wrinkling), and then realize the intelligent control of the forming process is of great significance.
