摘要
在传统的拉弯法基础上，提出了控制回弹的一种方法－－校正拉弯法。通过对板料在校正拉弯条件下的应力分析，根据回弹理论，推导出了回弹角与校正力及拉力之间关系的近似计算公式。
In this paper, a correcting tension bending method through which the bending rebound of plate can be controlled is put forward, based on traditional tension bending method.More- over, the author analyzes the stress of plate in the correcting ten- sion bending condition, and deduces an approximate calculation formula which can express the relationship among rebound angle, the correcting force and pulling force, based on the theory of re- bound.
