Abstract (en)
[origin: EP0453955A1] The invention proposes a drawing device in a press for drawing sheet metal formed parts. In order to achieve optimum support of the forces of the blank holder (6), the pressure cheek (8) is regulated in vertically adjustable fashion by a four-point control system which is known per se. In addition, vertically adjustable pins (7) with drives (15) are provided in order to make possible a selective local exertion of force on the blank holder (6). This is controlled or adjusted by means of displacement sensors (16) and force sensors (17). <IMAGE>
