高速冲压模具精密导向机构研究

Research on high speed stamping die precision-oriented machine

研究不同模具导向方式对高速冲压模具定位精度的影响。通过对传统多工位级进模具导向机构分析,提出这种导向机构由于滑动导柱导套间的配合间隙使模具合模时存在定位误差。指出传统多工位级进模具导向机构不能满足冲裁间隙和步距精度在微米级的引线框架零件多工位精密级进模的设计精度要求。设计出一种无滑动导向件、无定位精度误差的精密级进模具的导向机构,满足了精密零件级进模具的冲裁加工要求。

Different mould oriented means worked on high-speed stamping die of positioning precision were studied.Through analysing the traditional multi-position progressive-die oriented machine,it was found that the positioning error was between sliding guide pin and guide sleeve being gap.The traditional multi-position progressive die-oriented machine can not satisfy the design precision of matrix multi-position progressive die whose blanking clearance and step precision are micron-grade.The exact progressive die oriented machine of non-slip-oriented parts and no positioning error was designed to achieve the blanking processing requirements of precise parts in progressive die.
