ABSTRACT:
A horizontal hydraulic press comprises stationary plates, mounted on a bed and linked with columns upon which two slides can move. The slides are moved by double-acting hydraulic cylinders. In a similar way, between said slides there is installed an intermediate slide driven by its own double-acting cylinder. The piston side of this cylinder is connected to a pressure pipeline through a hydraulic distributor and to a return drain pipeline through said hydraulic distributor and a pressure regulator connected in series, while the rod side is connected directly to the pressure pipeline. The rod side of the hydraulic cylinder of one of the two slides is communicated with the pressure pipeline, and the piston side to the pressure pipeline and to the return pipeline through individual hydraulic distributors. Both the rod side and the piston side of the other slide are connected both to the pressure pipeline main and the return pipeline.
