ABSTRACT:
An apparatus for quick changing of tooling in heavy die sets is disclosed wherein interchangeable die shoes and tooling are piloted and guided on the bed of the press during operation of the same. Oil-hydraulic jacks lift the die shoe from the bed of the press and disengage the pilots and pneumatic cylinders disengage and retract the guides therefrom for roll-on and roll-off of the shoe from the press giving free access to the die shoe and to the underside of the blanking punch holder plate for repair or change of tooling. Guide sleeves for alignment of the blanking punch with the blanking die during operation of the press are pneumatically disengaged from leader pins in the die shoe providing transfer clearance for the roll-on/roll-off.
