摘要

A punch assembly for use in a punch press including a pair of elongated rods (20,10) having mating respective male (24) and female (14) threaded ends, a head on one end of the female portion for being engaged by a ram of the press, a compression spring (11), a punch tip (22) at the end of the male portion for action with a workpiece, a punch guide (40) encompassing part of the punch assembly to act as a stripper in relation between the punch tip and the workpiece and a wire clip (30) co-acting between the male (24) and female (14) threaded portions for adjustment of the overall punch length. After sharpening, the wire clip (30) is disengaged and the male and female rods are axially rotated in opposite directions to compensate for the ground-off length. The wire clip is then reengaged and the punch assembly is reassembled for use.
