Abstract
1,234,734. Stamping. CONTINENTAL CAN CO. Inc. 4 Feb., 1969 [5 Feb., 1968], No. 5990/69. Heading B3Q. A drawing punch 10 has an extensible nose 20 operated by fluid pressure for stripping a drawn article C from the punch. Fluid pressure may be applied to the inside of the article to assist the stripping action. As shown, the punch is hollow and receives a piston rod 30 one end of which carries the nose 20 which is biased to its extended position by compressed air supplied above a piston 41 on the rod. The bias is overcome during a drawing operation when the nose is pressed into the end of the punch, air trapped behind the nose escaping to atmosphere through passages 33, 52, 53, the clearance space between the punch and piston rod, passages 51, 47, 50, the space beneath the piston 51, passages 61, 62 and a valve 63. As the workpiece is stripped, atmospheric air returns to prevent collapse of the work, or the valve 63 is re-set for supplying compressed air to assist stripping. An accumulator 58 may be used for supplying air above the piston, or conduit 57 may be connected direct to check valve 60 which would be preferably solenoid operated.
