Abstract

Nach der Aufgabe sollen Linearmotor-Antriebe (5) in Pressen (1) mit einem oder mehreren Pressenstößeln (3) zum Antrieb dieser integriert werden. Es ist vorgesehen, den Hauptantrieb des Pressenstößels durch Antriebsmittel nach dem Linearmotor-Prinzip zu bilden und diese zwischen Pressengestell (1) und Pressenstößel (3) anzuordnen.

Figure 00000001
After the task, linear motor drives (5) should be integrated in presses (1) with one or more press rams (3) to drive them. It is intended to form the main drive of the press ram by drive means according to the linear motor principle and to arrange this between the press frame (1) and the press ram (3).
