Abstract

A hydraulic press can include a press frame with a press table arranged thereto and a traveling press platen arranged therein, in which at least one rapid motion cylinder with a platen connection can be arranged for the rapid no-load stroke of the press platen, in which at least one working cylinder with a piston directed toward the press table can be rigidly arranged on the upper crosshead of the press frame, in which a coupling device and opposed thereto a crosshead with at least one positioning and synchronizing cylinder for the piston can be arranged on the piston toward the press table, in which the piston can include a centrically arranged cylindrical extension for the sliding guide of a connecting device, such as a toothed rack, in which this connecting device can be connected to the press platen.
