异形件的滚压成形工艺设计及滚压线的调试

Design of Roll Forming Technology And Adjusting of Rolling Lines for Deformed Parts

该文对异形件的几处滚压工艺忌区诸如半径过大 ,不能使材料达到屈服成形状态 ;翻转 1 80°的成形 ;弯边太短 ,难以成形 ;重叠弯曲 ,材料易位移 ,难以控制等现象进行了讨论 ,提出了对滚压忌区的解决方法和设计要领 ,指出了在模具设计制造中应注意的事项 。

This paper discussed several avoidances of roll forming technology of deformed parts,such as the material can't bend to yielding status because of oversize radius, forming with flip 180°,forming difficulties with over short curve edge,overlapped bending,material shifting and difficulties of control. The solution of avoidances and design gist of roll forming technology were put forward. The notices in die design and manufacture were pointed,which have reference value to improve rolling precision.
