卷圆成型级进模的设计

Rolling circle shaping progressive die design

在级进模里夹人芯棒实现卷圆成型难度较大，一般情况下在排样时都将成型圆环轴线与送料方向搞成一致．尽量使模具结构简化利于实现，若是与送料方向相垂直，模具结构就复杂得多，设计难度增大不少。我们厂在设计研发链节级进模时，就遇到了这种状况，经过一番努力，最终完成了模具开发任务。现将我们的经验做个归纳总结与模具同仁共享。

in progressive die with the mandrel in realization of rolling circle shaping is difficult, in general in the layout will be forming ring axis and the feed direction into a consistent, as far as possible so that the die structure is simplified to achieve, if and the feeding direction is vertical, the die structure is much more complex, increased the difficulty of many design. Our factory in the design of R ＆ D link progressive die, encountered this situation, after a series of efforts, finally completed the mold development tasks. Now we will make a summary of the experience and die sharing.
