Abstract
A support apparatus for supporting a steering rack forged in a forging die, comprising a gripper to grip the shank of the rack, a lost-motion mechanism supporting the gripper and permitting limited movement in the direction of closing of the forging die, and a side-shift mechanism to move the gripper sideways. The lost-motion mechanism abuts the die assembly as the forging die closes thereby positioning the gripper to grip the shank of the steering rack during the final closing travel of the forging die. The gripper then lifts the steering rack as the forging die opens. The side-shift mechanism then moves the gripped steering rack sideways.
