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.

Abstract: A quick-change system for expediting installation of changes of progressive die tooling on single-acting presses having high slide/bed parallelism and slide-guide accuracy comprising tooling lanes having laterally-projecting tenons cooperating with lock means which mount on the press and in which the tooling is positioned by sliding and is cinched to location by heavily-leveraged means which clamp the tool onto the press using but a single manual operation.

Abstract: This invention relates to punch presses having a transfer die and a work transfer mechanism for advancing individual workpieces progressively through successive tooling stations of such die at high speed comprising dual intermittent-feed transfer bars slidingly mounted for rotary movement and lifting of said workpieces off the tooling stations of said die, and associated clampbars which retain each workpiece on the transfer bars by free retention of the edges of the workpiece during transfer movement, and which transfer bars deposit said workpieces at the next successive tooling station by rotary movement to release the lifting support of each workpiece from below the same and from the free-retention clamping thereof from above in readiness for the next tooling operation.

Abstract: A cupping tool for use in a double acting press to perform the operations of blanking, drawing and redrawing of sheet stock in predetermined timing sequence to form a cup during each stroke of the press and wherein the successive punching operations of telescoping, draw and redraw punches are governed by means of an automatic punch interlock means wholly enclosed within the body of the tool and actuated by relative movement of the draw punch and the tool body.
