Zusammenfassung:The disclosure relates to forging and pressing equipment, particularly, to presses exerting double action upon work. The press of the present invention comprises rams carrying males dies and rams carrying female die halves, mounted on the press framework for opposing reciprocation and associated with their own independent drives. The framework also supports a mechanism for clamping the female die halves, incuding, in accordance with the invention, wedges reciprocably mounted on the framework. The said wedges engage the rams carrying the female die halves along sloping planes provided on the last-mentioned rams at the sides adjacent to the male die-carrying rams, the wedges associated with different rams being coupled with one another and with their drive by a rocker arm spring-urged relative to the framework. The press can be used to advantage for making forgings of the pinion-and-hub type, flanged articles and the like, providing as it does reliable clamping of the female die halves throughout the pressing operation and thus preventing formation of flash along the plane of the opening of the female die halves, the press also providing for dimensional accuracy of the forgings, alongside of high capacity.
