- 1. 回弹角随凸模圆角半径和凸凹模间隙的增大而增大，随压边力、板料厚度、摩擦系数和材料硬化指数的增大而减小。
- The springback Angle increases with the increase of the punch round radius and clearances between the punch and the die while decreases...

- 2. 形状不良随板料厚度的增加、压边力的增加、屈服强度的降低、凸模曲率半径的减小而减小。
- The shape defect is decreased with increasing sheet thickness, increasing binder force, decreasing yield strength, and decreasing curvature radius.
