Abstract
Mechanism for effecting the fine adjustment of punch holders in a header or the like, which mechanism can be actuated from a readily accessible position on the machine, remote from the punch holder, and the mechanism being either entirely mechanical or partially hydraulic; supplemented by an alternative lock-up mechanism for use with punch holder studs for remote release of the holders to permit fine adjustment.
Claims16
Means for adjusting the position of a punch carried by a vertically movable slide in a header having releasable means for fixing the punch in operative position, comprising, for each punch, a backing plate slidably adjustable laterally relative to the slide, a punch carrier slidably adjustable vertically relative to the backing plate, means for applying oppositely vectored vertical forces to the punch carrier, means for applying oppositely vectored horizontal forces to the backing plate, means for actuating selectively said force applying means, all said actuating means being located remote from the points of application of said forces and in readily accessible positions adjacent the top of the slide, and force transmitting means operatively connecting said actuating means with the respective force applying means.
In a header having a punch carrier adjustably secured to a slide by at least one stud having a free end and a relatively fixed end, lock-up means comprising a threaded element on the free end adapted for tightening against the punch carrier, a threaded element on the relatively fixed end and remotely actuated means for rotating said last named threaded element between a locked-up position and a slightly released position.
