大锥角圆锥滚子用冷镦机冲压模具设计

Design of stamping mould of cold header for big cone angle conical roller

成品圆锥滚子半角大于3°的即为大锥角圆锥滚子。这种滚子采用卧式冷镦机加工时,在模腔内含料非常困难,产生掉料现象。深入探讨了产生此现象的原因,提出了解决方法,给出了计算公式。

Finished product conical roller whose half angle is greater than 3° is called big cone angle conical roller. Using horizontal cold header to process this kind of roller, it is difficult to keep the roller in the mould, the roller always falls from the mould. We thoroughly probe into the reason of this phenomenon, put forward the method to solve this problem, and give the calculated formula.
