Abstract

789,408. Punching. OCENASEK, J. W. Nov. 14, 1955 [Nov. 23, 1954], No. 32538/55. Class 83 (4). A punching unit, e.g. forming part of a subpress assembly, comprises a punch 1, a tubular stripper 3 and an interposed spring 4 surrounded by and retained in an outer casing 6, the punch 1 being adjustable relative to the outer casing 6 to a position in which it protrudes from the stripper 3. The punch 1 is adjusted relative to the outer casing 6 by a bolt 10 threaded in a block 7 secured to the casing 6. The bolt 10 acts through a spacer 8. With the punch 1, protruding, the punch may be inserted in a hole in a templet and the sub-press assembly may thus be located and then secured on the bed of a press. In a modification the adjustment is effected by a wedge or eccentric fitted in a transverse bore in the block 8. The unit may comprise a plurality of punches or punches of non-circular section co-operating with the dies 2 shown in Figs. 4 and 6. In this case provision is made to prevent rotation of the punches and dies.
