用于冲压件成形后冲孔的组合液压冲孔机床设计

Design of Combinative Hydraulic Punching Machine Tool for Punching after Stamping Workpiece

在已经成形的工件上再冲多个孔,以前往往需要在不同的冲床上进行多次操作。设计专用冲孔机生产线,可以一次装卡,同时完成3个纵向孔、4个横向孔的加工。该机稍作调整,还可以用来同时加工多个纵向孔、多个横向孔。

To punch again more than one hole on the formed workpiece, multiple operations in different punching machine tools are often required before. A dedicated production line of punching machine was designed, by which three vertical holes and four hori- zontal holes were processed simultaneously with once clamping. After making some minor adjustments, the machine can also be used to process a number of vertical holes and a number of horizontal holes.
