摘　　要：介绍了一种新型双层组合压边圈。在无需对常规薄板拉伸液压机进行改造的情况下 ,只需要改变压边圈的结构 ,即能实现连续、灵活方便地控制实际压边力的分布状态和大小 ,从而提高大型复杂零件的薄板拉伸成形性能。A new dual blank-holder is introduced.Only by changing the structure of the blank-holder,the variable blank-holding force can be controlled continuously and flexibly with this new blank-holder without rebuilding the ordinary hydraulic press.Thus the drawing performance of large and complicated sheet metal parts can be improved.
