利用PS 2F软件对矩形空心铝型材的拉弯成形过程进行了数值模拟，并生成了数控代码，对拉弯过程中弯曲半径的影响进行了分析，结果表明，当采用PS 2F软件自动确定钳口加载路径时，成形件端部的回弹量呈指数增长，而当采用PS 2F软件自动确定钳口加载路径时，成形件端部的回弹量呈指数增长在一定的弯曲半径下，随着弯曲角度的增大，回弹量增大;在弯曲角度相同的情况下，回弹量随弯曲半径的增大而线性增大;在弯曲半径和弯曲角度相同的情况下，型材的材料性能对回弹量有决定性的影响。
Stretch-wrap bending of rectangular hollow section aluminum profiles is investigated with the software PS2F,which is specially developed on an analytical algorithm aiming at the simulation of profile stretch 2D forming process as well as generation of a NC code to control the movement of the jaws of the machine.The focus is on the effect of bending radius,bending angle and material properties of profile on springback of the ends of the formed part with single curvature when the loading path of the jaws are automatically determined by the software PS2F.The results show that springback of the part ends increases exponentially with the increase of bending angle for a certain bending radius.For the same amount of bending angle,the springback increase linearly with the increase of bending radius.And for both the same bending radius and the same amount of bending angle,material properties of the profile have a definitive influence on the springback.
