Abstract

138,398. Hayward, T. A. Jan. 7, 1919. Punching; shearing; shear blades.- Plates such as ships' plates are trimmed on all four edges and punched at a single stroke of a press. The upper and lower platens a, c, Fig. 1, are connected by rectangular columns b serving as guides for the moving platen d, actuated by toggles g. The ends of the toggles and actuating connecting-rods have segmental projections g<2>, Fig. 6, and are hooped to maintain engagement with the pins h. Coupling-rods secure equal action of all the toggles. The hydraulic cylinders m are provided with auxiliary small rams for performing the idle part of the stroke. A series of bevelled-edged openings conduct the wads to lateral discharge springs x. The whole operative platen area is covered with punch-holders rand bolsters q, Fig. 9, arranged according to the grouping of holes required. The external edges of the outer bolsters co-operate with shear blades v. Spring plungers hold the plates down during the cutting and punching.
