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3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。

Analyzed three kinds of technological plans for the connecting plate forming：single process, compound process and progressive. It could be increased the size precision and the productivity of the workpiece by adopting the piercing-blanking continuous tecnnology, thus the product cost was reduced.And the structure of the piercing-blanking progressive die was designed.
