先落料后冲孔的级进模设计

Design of progressive die with blanking and piercing processes

介绍了一副先落料后冲孔的级进模,该模具吸取了级进模的优点以及制件材料的特性,在结构上成功地运用了弹性顶件装置,使落料后的料片得以继续进行冲孔加工。最终使有平面度要求的小孔零件在级进模中得到成功加工。

A progressive punching die with successive processes of blanking and piercing was introduced,which has absorbed the advantages of progressive die and the characteristics of product material.An elastic ejecting device was applied in the die to make it possible for the sheet to be punched after the blanking process.The parts with small holes and flatness requirements could be successfully punched by this progressive die.
