ABSTRACT:
A gap-framed type press has a horizontal bed which holds a lower die that cooperates with an upper die mounted on a vertically reciprocally movable ram to perform a metal-working operation therebetween. Hydraulic cylinders are operatively engaged with the ram for moving the die members into and out of engagement. The ram is movably mounted on a pair of spaced vertical side plates which are bolted to the press bed. The bed is supported on a pair of side frame members by a pair of spaced spherical bearings. The side frame members extend parallel with and closely adjacent to the ram-carrying side plates and are connected to the side plates by a sliding connection. The elastic bending and deformation forces which are applied to the press frame during each operation are transmitted between the side frame members and side plates through their sliding connection and between the bed and side frame members by the spherical bearings. The side frame members, side plates, ram and press bed will rotate about a horizontal axis extending between the center points of the spaced spherical bearings to maintain the upper and lower dies in parallel.
