Abstract
A forging apparatus has an upper die unit connected to an actuator for displacement in unison therewith, and a lower die unit confronting the upper die unit and mounted in a body assembly fixed to a foundation. An outer ring is guided axially by a plurality of guide pins for axial displacement on and along an outer circumferential surface of the lower die unit. The forging apparatus also has first ejector pins for removing a forged workpiece upwardly and second ejector pins for holding the workpiece when the upper die unit is displaced upwardly.
