    • Adjustable length punch assemblies are disclosed. An adjustable length punch assembly in accordance with present invention may be used with a punch press including a tool holder adapted to receive punch assembly and a ram adapted to move longitudinally along a ram axis. An adjustable length punch assembly in accordance with present invention preferably includes a punch body assembly disposed in threading engagement with a drive body assembly having a surface adapted to be struck by ram of punch press. The length of punch assembly may be adjusted by rotating of one body relative to other body. The adjustable length punch assembly preferably includes a lock mechanism for selectively preventing rotation of the punch body assembly relative to the drive body assembly. The lock mechanism preferably comprises a lock shaft coupled to one of bodies and a lock key slidingly coupled to other of bodies such that lock key slides along a lock key path. The lock key path is preferably disposed at an angle relative to ram axis when punch assembly is received by tool holder.
    • 公开了可调节长度的冲头组件。 根据本发明的可调节长度的冲头组件可以与冲压机一起使用,所述冲压机包括适于接收冲头组件的工具夹具和适于沿冲头轴线纵向运动的冲头。 根据本发明的可调节长度的冲头组件优选地包括冲头主体组件,其布置成与具有适于被冲压机冲头撞击的表面的驱动体组件螺纹接合。 冲头组件的长度可以通过一个主体相对于其他主体的旋转来调节。 可调节长度的冲头组件优选地包括用于选择性地防止冲头本体组件相对于驱动体组件旋转的锁定机构。 锁定机构优选地包括联接到主体中的一个的锁定轴和滑动地联接到其他主体的锁定键,使得锁定键沿着锁定键路径滑动。 当冲头组件被工具架接收时,锁定键路径优选地相对于压头轴线以一定角度设置。
