Abstract: Apparatus for forging a shaft flange comprises a forging press having a fixed plate and a moving platen. The moving platen carries a finish-forging die as well as a plurality of upper preforming dies while the fixed plate carries a rotary table having a series of like lower dies arranged in a circle. In use, a workpiece is carried by one of the lower dies sequentially into engagement with the upper preforming dies and the finish-forging die by rotational indexing movements of the table so that both the preforming forging operations as well as the finish forging operation are carried out in the same press. The finish-forging die is located substantially on the central axis of the press frame and the rotational axis of the table is spaced from this central axis.

Abstract: A drive mechanism for a pair of forging or stretching rollers comprising a hydraulic system including a pump, a hydraulic motor and switching means interposed between a main drive motor and the rollers.

Abstract: A wedge press is provided with a press frame; a reciprocatingly displaceable ram; a reciprocatingly displaceable wedge for acting on the ram; and means for effecting displacement of the wedge to cause the wedge to act upon the ram and thereby to effect displacement of the ram, with the wedge and the press frame having a pair of mutually engaging contact surfaces and the wedge and the ram having a pair of mutually engaging contact surfaces, and at least one said pair of mutually engaging contact surfaces having a special configuration to provide improved guiding of the wedge.
