拉弯成形中导轨型材的回弹计算

Calculation of Spring Back on Stretch Bending Metal Sections of Car's Middle Sliding Rail

分析了用拉伸弯曲法成形面包汽车中导轨零件时的尺寸和角度回弹 。

This paper analyses the spring back of car's middle sliding rail on stretch bending.A feasible method of theoretical calculation is given to determine parameters of spring back.The method is also used to design dies suitable for similar type.
