联接板冲孔落料级进模设计

Design of Piercing-Blanking Progressive Die for the Connecting Plate

分析了联接板的三种工艺方案，单工序、复合工序及连续工序，采用冲孔落料连续工艺，能提高工件的尺寸精度及生产率，降低生产成本。介绍了联接板毛坯的排样图、冲压力及压力中心的工艺计算，设计了联接板冲孔-落料级进模的模具结构。

This paper analysed three kinds of technological plan for the connecting plate.single process,compound process pro-gressive.It could be increased the dimension precision and the productivity of the workpiece by adopting the piercing-blanking continuous tecnnology,thus the product dost reduced.The tech-nological calculation of the blank layout.the stamping force and the pressure centre for the connecting plate were introduced, and the die structure of the piercing-blanking progressive die for the.
