Abstract:
A die apparatus for forging a steering rack from a bar. The die apparatus comprises a first and a second bolster movable towards each other, and at least one gripper adapted to grip the bar as the rack is forged. The gripper comprises first and second gripper halves carried by, and movable relative to, the first and second bolsters respectively. A gripper bias means biases the gripper halves towards each other. As the bolsters move towards each other to forge the rack, the first gripper half abuts against the first bolster, and the second gripper half abuts the second bolster.
