ABSTRACT:
A upset forging machine assembly (20) including a pair of gripper dies (22, 24) for gripping forging stock in a closed position and movable to an open position for receiving stock and removing a forged part. A gripper drive mechanism (34) moves the gripper dies (22, 24) between the open and closed positions. A header (84) is removably clamped to a header support member (36) by multiple pairs of studs (72) extending from the header support member (36) with each stud (72) having a head (78) disposed in an associated channel (90) in the header (84). An actuation mechanism (92, 94) moves the studs (72) between a clamped position and a release position. A tool punch (142) is supported by the header (84) for upsetting the forging stock. Having the header (84) clamped to the header support member (36), a header drive mechanism (46) moves the header support member (36) to a forging position is when the gripper dies (22, 24) are in the closed position. In turn, the header drive mechanism (46) moves the header support member (36) to a retracted position. At the same time, the gripper drive mechanism (34) moves the gripper dies (22, 24) to the open position allowing the forged part to be removed.
