Abstract: A press is described which is particularly suitable for the production of precision moldings from pulverized materials. The press is provided with a frame 3 in which a draft frame 5 and a platen 4 acting together provide the axis, and are connected to one another by means of a mechanical drive, preferably a toggle drive system, for relative movement to form a main press ram. In the main press ram, between the movable draft frame 5 and the platen 4, a hydraulic subpress 12 is arranged together with at least one additional axis, preferably however with several such axes. Control and regulation of the timing and extent of the working movement of each axis in the hydraulic subpress 12 are made to depend, through a control system 22-33, on the working movement of the main axis formed by the draft frame 5 and the platen 4 of the mechanical press 2.

Abstract: A press for producing dimensionally stable moldings from powdered materials is described whereby a press frame and a press platen are provided in a press body and are linked together in movement by means of a drive and form a main press plunger. A hydraulic press part with at least two additional press axes is mounted in front of the main press plunger between the press frame and press platen. The second hydraulic press axis of hydraulic press part is actuated and controlled by its first axis through a hydraulic coupling device that has a variable transmission ratio, while the first axis of the hydraulic press part is in turn actuated by the press frame of the main press plunger. The movement ratios of the second press axis of the hydraulic press part can then be varied relative to the main press axis.
