Abstract (en)
[origin: EP0713735A1] Length compensating arrangement for a hold-down between the top and the bottom tool of a press, in which a number of interconnected short-stroke cylinders (5) with pressure pins (7) connected to their piston rods (6) are mounted on a pressure pin plate (3) to clamp the sheet blank between the top and bottom tool. The short-stroke cylinders (5) are pressure connected to a compensating cylinder (10), so that prior to the start of drawing the fluid volume displaced in the short-stroke cylinders (5) by forces acting on the pressure pins (7) is stored in the compensating chamber (22) of the compensating cylinder (10).
