Abstract

Die Erfindung betrifft eine Presse mit einem Kniehebelantrieb, der einen mit einem Ende an einem Pressengestell (10) angelenkten Stützschenkel (15), einem mit einem Ende an einem am Pressengestell (10) geführten Arbeitsstößel (26) angelenkten Antriebsschenkel (24), sowie einen Dreieckslenker (19) aufweist, der mit einem Ende an einem Kurbelantrieb (22) angelenkt ist, und an dessen anderem Ende der Antriebsschenkel (24) arbeitsstößelseitig und der Stützschenkel (15) gestellseitig mit ihren jeweiligen anderen Enden unter Bildung von Kniegelenkpunkten (23, 18) mit Abstand zueinander angelenkt sind. Um bei einem möglichst einfachen Aufbau der Presse diese an vielfältiger Arbeitsaufgaben schnell anpassen zu können, ist erfindungsgemäß vorgesehen, daß die Länge des Dreiecklenkers (19) zwischen Kniegelenk und Kurbelantrieb (22) verstellbar ist.

Figure 00000001
The invention relates to a press with a toggle lever drive, which has a support leg (15) articulated at one end to a press frame (10), a drive leg (24) articulated at one end on a working ram (26) guided on the press frame (10), and a Has triangular link (19), which is hinged at one end to a crank drive (22) and at the other end of the drive leg (24) on the working ram side and the support leg (15) on the frame side with their respective other ends to form knee joint points (23, 18 ) are articulated at a distance from each other. In order to be able to quickly adapt the press to a wide variety of work tasks with the simplest possible structure, the invention provides that the length of the triangular link (19) between the knee joint and crank drive (22) is adjustable.
