Abstract

Die Erfindung betrifft eine Presse mit elektrischem Antrieb, welcher mittels einer hydraulisch beaufschlagten Kupplungs-Brems-Kombination (2) mit einer Kurbelwelle (3) wirkverbunden ist. Die Bewegungen und Kräfte der Pressenstößel werden erfindungsgemäß dadurch beeinflusst, dass eine veränderbare Druckerzeugung für den hydraulischen Druck zur Betätigung der Kupplungs-Brems-Kombination (2) vorgesehen ist, die mit der Bewegung der Kurbelwelle (3) steuerungstechnisch gekoppelt ist. Alternativ kann die Kupplungs-Brems-Kombination (2) auch über eine andere Beaufschlagungsvorrichtung, z.B. einen Spannungs-Weg-Wandler betätigbar sein.

The invention relates to a press with electric drive, which by means of a hydraulically acted clutch-brake combination (2) with a crankshaft (3) is operatively connected. The movements and forces of the press ram are inventively influenced by the fact that a variable pressure generation for the hydraulic pressure to actuate the clutch-brake combination (2) is provided, which is coupled control technology with the movement of the crankshaft (3). Alternatively, the clutch-brake combination (2) via another application device, such as a voltage-way converter can be actuated.
