ABSTRACT:
Redraw carriage apparatus (28) for use with a crank and slide press (10) includes a redraw carriage (32) that is secured to frame members (14a and 14b) by spaced-apart guide rods (34), and by spaced-apart support frames (36 and 37) that are bolted to respective ones of the frame members (14a and 14b) by cap screws (30), that are homed against one of the frame members (14b) by homing cap screws (76), and that support first and second (60 and 62) ends of the guide rods (34). Removal and replacement of the redraw carriage apparatus (28) is achieved by removal of the cap screws (30 and 76) and by movement of the redraw carriage apparatus (28), without disturbing alignment of a tool pack subassembly (16), by movement that is transverse to a longitudinal axis (24).
