Abstract

1,249,326. Punching. PORTER PRECISION PRODUCTS CO. 9 Sept., 1968 [11 Sept., 1967], No. 42750/68. Heading B3W. A guide bush for the punch 14 of a punch press is formed by placing a blank 5 of plastics material, such as polyurethane, having a hardness between 50 Shore A and 75 Shore D in a bore 39 in a stripper plate 6 of the press and driving the punch through the blank. The thimble-shaped blank shown is inserted in the bore from below and the ram of the press lowered under hand control to force the blank into press-fit engagement with the bore. The punch is then forced through the blank. For use in punching workpieces having a finished top face, e.g. enamel, the bush blank has a flange (28) around its lower face which partly seats in a recess (48) in the stripper plate, Fig. 12 (not shown). The plastics guide bush being in pressure-bearing contact with the nib of the punch at the point of impact absorbs the impact forces.
