Optimizing Design on Punch Cone Angle of Motor Commuter

电机换向器整体冷锻模冲头端部锥角优化设计

It calculated the cone angle of the punch and gave out the radial equation of the punch as well as the equation of the spring.

计算出凸模锥面角度值，给出凸模径向运动方程式及弹簧力表达式。

Now we have designed a assembling die with hinge type punch, it can solve the problem of 180 ° angle bending of the ballast ′ s shell edge.

现设计了一套采用铰链式凸模的镇流器装配模，能较好地解决镇流器壳边180°弯曲的难题。

The springback angle increases with the increase of the punch round radius and clearances between the punch and the die while decreases with increase of the blank holder force, sheet thickness, friction coefficient and material hardening exponent.

回弹角随凸模圆角半径和凸凹模间隙的增大而增大，随压边力、板料厚度、摩擦系数和材料硬化指数的增大而减小。
