Abstract
Die Erfindung betrifft eine Antriebsvorrichtung für einen Pressenstößel (7) einer Umformpresse, wobei mit einem, einem Schwungrad-Antrieb (8) nachgeordneten Getriebe, vorzugsweise einem Planetenradgetriebe, eine direkte Ansteuerung der Stößelbewegung des Pressenstößels (7) erfolgt. Vorzugsweise kann das Getriebe zusätzlich mit einem Zusatzantrieb zur Variation der Pressenstößelgeschwindigkeit beschaltet sein. The invention relates to a drive device for a press ram (7) of a forming press, with a direct control of the ram movement of the press ram (7) being carried out with a gear, preferably a planetary gear, arranged downstream of a flywheel drive (8). The transmission can preferably also be connected to an additional drive for varying the press ram speed.
