摘要： 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.
摘要翻译： 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。

摘要： A self-aligning multi-tool for use in a punch press having a ram. The multi-tool includes a housing carrying a striker and a magazine bearing a plurality of circumferentially spaced tools and rotatable with respect to the housing so as to bring a single desired tool into alignment with the striker. The housing has a striking surface adapted to be engaged by the ram of a punch press and configured to rotationally lock to the ram when correctly rotationally aligned therewith to prevent the housing from rotating as the magazine is rotated. The housing is provided with at least one alignment pin having a tapered cam surface and positioned such that the ram will contact and cam against the tapered cam surface of the pin as the ram approaches the striking surface if the machine ram and the striking surface are rotationally mis-aligned so as to urge the housing to rotate into correct alignment with the ram to enable rotational locking therebetween.
摘要翻译： 一种用于具有压头的冲压机的自对准多工具。 该多工具包括承载撞击器的壳体和带有多个周向间隔开的工具并且可相对于壳体旋转的仓库，以使单个所需工具与撞针对准。 壳体具有适于由冲压机的冲头接合的冲击表面，并且被构造成当与冲头正确地旋转对准时旋转地锁定到冲头，以防止当弹匣旋转时壳体旋转。 壳体设置有至少一个具有锥形凸轮表面的对准销，并且定位成使得当冲头和冲击表面旋转时，当压头接近撞击表面时，压头将接触并凸轮抵靠销的锥形凸轮表面 不对齐，以便促使壳体旋转成与冲头正确对准，以在其间进行旋转锁定。

摘要： An American style press brake tool and tool holder having a safety key. The holder has a body with walls defining a downwardly open, tool receiving recess having a top, a downwardly facing force-delivering shoulder adjacent the bottom of said recess, and a shelf within said recess having an upwardly facing surface spaced upwardly from said force-delivering shoulder. The tool comprises a body having a lower work-engaging surface, an upwardly facing force-receiving shoulder engageable with the shoulder of the tool holder, and an upwardly extending tang receivable in said recess, the upper end of the tang being spaced from the top of the recess. A manually operable actuator is spaced below said force-receiving shoulder, and a safety key is coupled to the actuator for movement horizontally into and out of alignment with the shelf between locked and unlocked positions, respectively.
