ABSTRACT:
A press for converting work pieces into finished parts has an elongated bolster mounted on a press bed. The bolster supports columns on which a ram is slidable. The bolster also supports the lower die shoe of the press tooling. A conveyor or transfer system mounted on the bolster carries work pieces into and out of the area of the tooling. The bolster is a unitary piece which integrates support of the die shoe, columns and conveyor to assure proper cooperation and alignment among them. A pivotable carrier mounts a feed mechanism for feeding a stock strip into the tooling. Power to the feed mechanism is supplied through a shaft which is coaxial with the hinge line of the carrier, so that the carrier can be swung away from the tooling for service access without requiring disconnection of the power supply. A traveling vacuum box on the lower die shoe supports the conveyor for vertical as well as longitudinal motion, and retains the work pieces on the conveyor.
