1 前言 对于V形及U形弯曲件,进行弯曲加工后都会有一定回弹值。在设计模具前应掌握材料的回弹规律及回弹值的大小,以便采取措施,使其修整量减小。回弹一般包括弯曲半径回弹值和角度回弹值。
1 Introduction For V-shaped and U-shaped bending pieces, there is a certain rebound value after bending. In the design of the mold should grasp the rebound laws of materials and the size of the rebound value in order to take measures to reduce the amount of dressing. Rebound generally includes bend radius rebound value and angle rebound value.
