在设计冲裁模时,凡在模具结构上采用弹性元件进行脱料的(即从凸模上脱下工件或废料),需要对脱料力进行计算,在带有冲裁工步的级进模设计中,脱料力的正确计算尤为重要。 过去,我厂在计算确定这类型式的脱料力时,参考应用了一些外来资料,这些资料除了考虑冲裁力大小的因素外,另外仅考虑到搭边尺寸大小的因素,而对于冲裁间隙的 In the design of blanking die, where the die structure using elastic components for de-bonding (that is, from the punch off the workpiece or scrap), you need to calculate the de-feeding force, the step with blanking steps Mold design, the correct calculation of the removal of force is particularly important. In the past, I plant in determining the type of this type of removal of force, the reference to the application of a number of external data, in addition to considering these factors in the size of the blanking force, the other only take into account the size of the edge of the size of the factors, and blanking Clearance
