Extrusion press with electro-hydrostatic control system

Abstract

The present invention relates to an extrusion press (10, 20, 30) with a press cylinder (111), the press cylinder (111) being driven with an electro-hydrostatic control system (104) for a power transmission and being connected to a separate drive (120, 400) for rapid traverse, with a container (115), wherein the container (115) is connected to a hydraulic cylinder (117) for a power transmission and to a further separate drive (119, 300) for rapid traverse, with a hydraulic cylinder (101) with a locking device (103) for driving a shearing tool (102), wherein the hydraulic cylinder (101) is connected to the electro-hydrostatic control system (104), and wherein the press cylinder (111) in the power transmission and the hydraulic cylinder (101) for driving a shearing tool (102) are controlled alternately via the common electro-hydrostatic control system (104).
