Abstract (en)
[origin: EP0510507A1] In order to select the pressure pins (6) acting on the blank holder (5) in the die lower part (4), there are fastened, between the actual drawing apparatus (8), acting on a pressure cheek (9), and the pressure pins (6), further pressure cylinders (10, 12) in the pressure cheek (9), which pressure cylinders can be driven individually via valves (16) from a pressure line (18, 19). As a result, it is possible to influence in a precise manner both the drawing conditions of different sheet-metal parts and their ejection movement from the die lower part. <IMAGE>
