ABSTRACT:
A hydraulic press for compacting materials with a large platen area has a platen support comprising of four hydraulic cylinders, one at each corner of a rectangular or square shaped platen. The cylinders are supplied with near equal fluid flows from commercially available hydraulic flow dividers. When an off-centered platen loading is encountered, the cylinders will respond with a higher restraining force from the cylinders nearest the load with relatively small bending moments transferred to the cylinder rods. The resulting platen structural load resembles a beam supported with pinned connections. The resulting press capacity can be significantly higher than that achievable with guided type platen supports of similar costs where the bending moment is restrained by the stiffness of the guides.
