当前模具制造发展的水平要求采用带料在模具中自动送料又可以快速调正的通用机构,并且具有高精度的冲切步距。 现在所知道的通用机构都是只有比较低的冲切步距精度,一般为(0.05～0.1mm),在冲切高精度、多步距的零件时,实际上就不可能应用。 苏联工具研究所的电机分所研究并运用 The current level of mold manufacturing development requires the use of materials in the mold with automatic feeding can quickly adjust the general institutions, and with high precision punching step. Common mechanisms now known are only relatively low accuracy of the die-cutting step, typically (0.05 to 0.1 mm), which is practically impossible to apply when cutting high-precision, multi-step parts.
