Die apparatus for forging steering racks

A support apparatus for supporting a steering rack forged in a forging die, the forging die comprising a first die assembly and a second die assembly movable towards each other from an open position to forge the steering rack from a bar loaded into the first die assembly, the support apparatus being separate from the second die assembly and configured to be directly attached to the second die assembly,

• the support apparatus comprising:
• a gripper adapted to grip a shank of the forged steering rack, the gripper being adapted to be open when the forging die is in the open position and the bar is loaded;
• a lost-motion mechanism supporting the gripper and configured to permit limited relative movement between the gripper and the second die assembly in the direction of closing of the forging die;
• and
• a side-shift mechanism adapted to move the gripper in a sideways direction substantially transverse to an axis of the steering rack and transverse to the direction of closing of the forging die,
• wherein:
• the lost-motion mechanism is adapted to abut the first die assembly as the forging die closes to forge the steering rack from the bar placed in the forging die thereby positioning the gripper to grip the shank of the steering rack during a final closing travel of the forging die,
• the gripper is operable to grip the shank of the steering rack whilst the lost-motion mechanism abuts the first die assembly,
• the gripper is adapted to lift the gripped steering rack away from the first die assembly as the forging die opens, and
• the side-shift mechanism is adapted to move the gripped steering rack in the sideways direction to enable another bar to be placed in the forging die whilst the steering rack is held by the gripper,
• wherein the lost-motion mechanism is biased towards the first die assembly and includes springs, and
• wherein the side-shift mechanism includes a bearing rail.
