A fluid powered compression molding press or the like in which members such as platen members are movable relatively toward one another to develop high pressures therebetween, such as for instance forming a workpiece or work material in a compression die, and including means for compensating for tilting movement of the movable member relative to the other member by creating a force moment acting on the movable member in a direction opposite to the direction of tilting movement. The compensating means includes leveling units adapted for engaging coaction with the movable member and coupled into a closed fluid system including slave units and a control unit operatively connected together, whereby the control unit operates to generate reaction pressure in the respective leveling unit via the respective of said slave units.

425406

A fluid powered press comprising a first platen and a second platen with at least one of the platens being reciprocably movable along a predetermined axis relative to the other platen and having motor means for so moving the movable platen, and a leveling system therefor. The leveling system comprises a plurality of hydraulic leveling piston and cylinder units mounted on one of the platens with each of the leveling units including a projecting rod member connected to the piston of the respective leveling unit and movable with the piston axially relative to the cylinder of the respective leveling unit. Reciprocal fluid powered motor units mounted on the other platen coact with wedge locks for selectively coupling the rod members to the other platen. Means are provided for maintaining the leveling unit cylinders filled with hydraulic fluid; and conduit means communicate pairs of the leveling units together in a closed loop system, with such leveling units when coupled to the other platen resisting tilting movement of the platens relative to one another during operation of the press.

72184

A forging press comprising a base with a pressure roller mounted in spaced relation to the base and in conjunction with the latter defining a pressure zone, with a mechanism for conveying work between the base and the roller through the zone. The work conveying mechanism includes a plurality of discrete generally relatively movable die segments coacting with a confining frame, for maintaining the die segments in assembled but movable relation relative to one another, and providing for the aforesaid movement responsive to pressure applied to the die segments by the roller and the formation or step forging by the die segments of an associated work blank into a produced part, during passage of the mechanism and the work blank through the zone. Each die segment includes a roller pressure end and a molding end, and a pressure transmitting insert movably coacts with the roller pressure end of each die segment, and provides for mating relation of the insert with the roller, during movement of the work through the zone, whereby the part is generally smoothly forged from the work blank into finished to close to finished condition.
