Abstract

1,266,313. Stamping. GULF-WESTERN INDUSTRIAL PRODUCTS CO. 14 April, 1970 [26 Aug., 1969], No. 17723/70. Heading B3Q. A device for ejecting a workpiece such as a can top from between a reciprocating stamping punch C and a stationary die D in a press mounted at an angle to the vertical comprises a pivotally mounted kicker arm 46; a guide 52; for a kicker slide 50, mounted on the die D ; a link 60 connecting the arm 46 with the slide 50; and cam means 84 for pivoting arm 46 to reciprocate the slide in a straight line into and out of the die area E when the punch is operated. The can tops are blocked and drawn from a metal strip by four sets of dies 20, 24 positioned diagonally between opposite corners of their respective die shoes 12 and 22. Cam operated knock-out pins 30 (Fig. 3, not shown) then push the formed parts from the upper dies 20 into the space between the upper and lower dies where they are ejected on to a conveyer G by ejectors I. The can tops from the first and second die sets nearest to the front of the press i.e. to the left in Fig. 1, are ejected by spring biased, cam operated kicker arms 36. The can tops from the remaining die sets are ejected by the kicker slides 50 being moved into the die area by the spring force of a dashpot 66 when cam follower 92 on the punch C runs on to the upper part of cam plate 86.
