圆筒形拉伸冲压零件下料公式的修正方法

在冲压拉伸制造薄板形零件的模具设计制造中,通常都是先利用公式计算出落料尺寸,根据这个尺寸制造出落料凸模和落料凹模,试生产后再根据制件的误差对落料凸模和落料凹模进行修改,如果成本高,效率低,就通过探讨误差生成的原因以及做出应对的修正方法,从缩小误差,提高试生产效率方面考虑,设法缩短试制时间。

Correction Method of Batching Formula of Cylinder Press Parts

In die design manufacturing of thin plate parts through press and pulling,operators have to calculate out batching sizes through formula first,and then turn out batching male die and female die.After the trial production,they correct batching male die and female die according to errors of manufactured pieces,which is of high cost and low efficiency.The article discuss reasons for the generation of errors and the corresponding correction method so as to shorten the trial production time through reducing error and enhancing production efficiency.
