针对某电子产品连接板的冲压工艺,在对冲孔、翻孔、落料和弯曲等成形工艺分析的基础上,提出了多工位级进模的冲压方案。根据零件的形状、尺寸精度要求,采用了侧刃初定距,导正孔精定位。在保证工件的尺寸和形状位置精度要求的同时,提高了材料的利用率和劳动生产率。 Aiming at the stamping process of an electronic product connecting plate, the stamping scheme of multi-position progressive die is proposed based on the analysis of forming processes such as punching, punching, blanking and bending. According to the shape of parts, dimensional accuracy requirements, the use of the first edge of the side edge of the blade, guide the hole precision positioning. In ensuring the workpiece size and shape of the position accuracy requirements, while improving material utilization and labor productivity.
