| 摘 要： | 汽车纵梁是一种形状和尺寸都比较大的冲压件,弯曲成形难度大且回弹不易控制。通过对U形件工艺和模具加工的分析,提出了解决回弹的工艺方法及可控制回弹的弯曲模改进设计,使汽车纵梁弯曲成形后的质量有了较大的提高,从而消除了由于产生回弹使零件侧壁的孔位与底部尺寸超差而影响纵梁装配等问题。

| Abstract: | Auto girder is a kind of stamping parts with complex shape and large size so that its bending forming is difficult and springback is not easy to control.By analysis of manufacturing processes of U-shape workpiece and its die,the author puts forward a method to solve the springback,and proposes improvement design of the die to control the bending springback.Thus,the quality of bending forming of auto girder is greatly improved and the problems affect the assembly of the longitudinal beam,caused by the hole location at side wall and at the bottom size out-of-tolerance due to the rebounding,are solved. |
