A stamping and forming machine is disclosed having two operating modules, each of which has a punch assembly and a mating die assembly that reciprocate horizontally toward and away from each other for performing stamping and forming operations. The punch and die assemblies reciprocate within a passageway formed by a tool box comprising a base plate, two side plates screwed to the base plate, and a cover plate that is removably attached to the side plates. The cover plate is attached by means of dovetails that are formed in the outside edges of the side plates and the cover plate. The dovetails are spaced so that when the dovetail halves on one side of the cover and a respective side plate are in mating engagement, the other dovetail half on the cover is spaced from the dovetail half on the other side plate. A removable gib is arranged to closely fit in this space so that there is no appreciable lateral play between the cover and the side plates. The cover is removed by first sliding the gib out of the space, moving the cover laterally a small amount to break the oil film, then lifting the cover straight up. The cover is reassembled by lowering it onto the top surfaces of the side plates, sliding it to one side to mate the two dovetail halves, then inserting the gib into the space between the other two dovetail halves.

Modular tooling box with a removable cover for a stamping and forming

A stamping and forming machine is disclosed having two operating modules, each of which has a unique scrap removal system. The machine includes a punch assembly and a mating die assembly that reciprocate horizontally toward and away from each other for performing stamping and forming operations. The die assembly includes a die plate having openings for mating with punches in the punch assembly, a die backup plate having scrap receiving openings, and a ram for effecting the reciprocating motion. An adapter is disposed between the die backup plate and the ram and is carried thereby. Horizontally disposed openings are formed in the adapter in corresponding alignment with the scrap receiving openings. Vertically disposed openings are formed in the bottom surface of the adapter and extend upwardly to intersect the horizontal openings. A conveyer is arranged vertically under these vertically disposed openings and leads to a position outside of the machine. During operation, scrap slugs formed during the stamping process are forced by the punches through the scrap receiving openings where they enter the horizontal openings and fall by gravity through the vertical openings to the conveyer and conveyed to the outside of the machine.
