    • An adjustable length punch set assembly for adjusting the overall length of a punch having a punch driver and punch holder that are axially adjustable relative to each other and retained at least in part within a punch guide sleeve and biased axially with respect thereto by a biasing spring. A locking push button is positioned axially within and accessible through a hole of the punch driver, the push button being moveable between a first position for locking the punch driver with respect to the punch holder to prevent length adjustment by rotation of mutually engageable threaded portions thereof, and a second position allowing relative rotation of the punch driver and punch holder along the mutually engageable threaded portions to effect length adjustment. The push button includes one or more detents formed thereon, the detents being engageable with one or more first detent stop(s) formed in the punch driver and second detent stop(s) formed in the punch holder. The number of second detent stops in the punch holder preferably is less than the number of first detent stops of the punch driver, such that the number of first detent stops in an integer multiple of the one or more detents of the push button. A spring is provided for biasing the locking push button into the first position. The spring is depressible by an external force applied through the hole in the punch driver to the push button thereby moving the push button into the second position.
    • 一种可调节长度的冲头组件,用于调节具有冲头驱动器和冲头保持器的冲头的总长度,所述冲头驱动器和冲头保持器可相对于彼此轴向调节并且至少部分地保持在冲头引导套筒内并且通过偏置弹簧 。 锁定按钮轴向地定位在冲头驱动器的孔内并且可通过冲头驱动器的孔进入,该按钮可在第一位置和第二位置之间移动,该第一位置用于相对于冲头保持器锁定冲头驱动器,以防止通过相互接合的螺纹部分的旋转来进行长度调节 以及允许冲头驱动器和冲头保持器沿着相互接合的螺纹部分相对旋转以实现长度调节的第二位置。 按钮包括形成在其上的一个或多个棘爪,棘爪可与形成在冲头驱动器中的一个或多个第一止动止动件和形成在冲头保持器中的第二止动止动件接合。 冲头架中的第二止动件的数量优选小于冲头驱动器的第一止动止动件的数量,使得第一制动器的数量以按钮的一个或多个棘爪的整数倍为单位停止。 提供弹簧以将锁定按钮偏压到第一位置。 弹簧可以通过穿过冲头驱动器中的孔施加到按钮的外力来压下,从而将按钮移动到第二位置。

    • A punch guide sleeve and stripper plate assembly useable with a punch set of the type having a punch disposed within the punch guide sleeve and adapted to be reciprocally advanced through an opening of the stripper plate attached to one end of the punch guide sleeve by the ram of a punch press. The stripper plate assembly includes a rotatable stripper plate cap which may be manually rotated with respect to the guide sleeve end from a locked to an unlocked position to secure and release the stripper plate through tightening and loosening a retaining wire onto and away from the stripper plate. The retaining wire is preferably substantially circular in cross-section and split to provide two unconnected ends that are attached to the stripper plate cap and the guide sleeve. When these two ends are drawn together in the locked position, the arcuate wire will be diametrally compressed for engagement with the stripper plate. Preferably, a spring loaded button and catch arrangement is provided that releasably locks the stripper cap in the locked position to maintain the retaining wire in contact with an annular edge portion of the stripper plate.
    • 一种冲头引导套筒和剥离板组件,其可用于具有设置在冲头引导套筒内的冲头的类型的冲头组件,并且适于通过冲头引导套筒的一端附接到冲头引导套筒的一端的往复推进 的冲压机。 脱模板组件包括可旋转的剥离板盖,其可以相对于引导套筒端部从锁定位置手动地旋转到解锁位置,以通过将保持线紧固并松开剥离板来脱离剥离板来固定和释放剥离板 。 保持线优选地基本上是圆形的横截面并且分开以提供两个未连接的端部,其连接到脱模板盖和导向套筒。 当这两个端部被锁定在一起时,弓形线将被径向压缩以与剥离板接合。 优选地,提供弹簧加载的按钮和止动装置,其将剥离器盖可释放地锁定在锁定位置,以保持保持线与剥离板的环形边缘部分接触。
