Abstract

Zum Abstützen eines auf einer Matrize (3) aufliegenden Blechteiles (2l), welcher während des Pressvorganges eine Schwenkbewegung nach oben ausführt, ist eine vertikal be­ wegliche Stützeinheit (l0) vorgesehen. Die Bewegung der­ selben ist mit der Stösselbewegung koordiniert und mit einer Geschwindigkeit (vs) ausgeführt, die zur Geschwindigkeit (vp) des Stössels in einem bestimmten Verhältnis steht. Die­ ses Verhältnis entspricht dem Verhältnis des Abstandes (b) zwischen der Stütze (9) und der dieser zugekehrten Kante (22) der Matrize zur halben Matrizenbreite. To support a sheet metal part (2l) resting on a die (3), which performs a swiveling movement upwards during the pressing process, a vertically movable support unit (l0) is provided. The movement of the same is coordinated with the plunger movement and is carried out at a speed (v s ) which is in a specific ratio to the speed (v p ) of the plunger. This ratio corresponds to the ratio of the distance (b) between the support (9) and the edge (22) of the die facing it, to half the die width.
