ABSTRACT:
A press structure wherein the usual crank mechanism is utilized solely for the movement of the press tooling and forging pressure is exerted by way of load cylinders interconnecting the press ram and load beam so that the press ram and load beam are drawn together under the influence of high pressure hydraulic fluid within the load cylinders. A minimum volume of high pressure hydraulic fluid is required to exert the forging pressure and, accordingly, the work efficiency of the press is much greater than that experienced with other press systems.
