多工位高速冲压级进模具错层模板结构

分析平行模板结构的级进模具,由于受到模板厚度的限制,模具凸模长度较长。当凸模截面尺寸小,且采用硬质合金材料时,凸模抗冲击性能差,冲裁中易发生折断。该类模具结构不适合采用高速精密级进冲模加工产品尺寸小、生产批量大的电子产品。文章提出一种新型错层模板模具结构,有效缩短冲裁凸模长度,提高了硬质合金凸模抗冲击性能,避免凸模在高速冲压条件由于振动发生折断。

Research on multi-position progressive die structure of split-level templates for hight speed stamping

For the progressive-die with parallel templates,the length of punch is rather long due to the limit on the thickness of the templates.When the punch section is of small size and using carbide materials,the punch resistance is poor and easy to break up.Such die structure is not suitable for manufacturing small parts in large quantity by using high speed precision progressive die.The die structure with split-level templates could shorten the length of punch,improve carbide punch shock resistance and avoid the...
