Abstract
794,946. Rolling. MICHIGAN TOOL CO. July 19, 1956 [Dec. 1, 1955], No. 22391/56. Class 83 (4). In a method of rolling gear teeth, splines, &c., the workpieces 64, Fig. 4, are supported on a fixed axis and are engaged by platens 50, 52 on opposite sides and moving simultaneously in opposite directions by hydraulic means. The tools 50, 52 are mounted on slides 32, 34, Fig. 3, running on slideways 24, 34 and movable by hydraulic cylinders 74, Fig. 1, having piston rods 80 coupled to projections 82 on the slides. The platens 50, 52 are attached to the slides by brackets 46 and bolts 48, 54 and are adjustable by backing wedges 68, 70 which are moved by adjusting screws 67. Synchronization of the platens is obtained through a gear 98 running on a fixed support member 102 and engaging racks 94, 96 on the slides 32, 34. Lubrication for the gear 98 and slides 32, 34 is provided through ducts such as 146, 148. The work 64 is supported between centres 114, 166 and the centre 114, Fig. 3, is attached to a slide 108 which is adjustable within the support 102 by a screwed rod 116 rotatable at a wrench-engaging end 132 and located by a thrust bearing 126. The other centre 166 is carried by a slide 158 which is movable along a slideway 154 to accommodate various lengths of work. The centre 166 is rotatable in bearing 170 and retractable by an hydraulic cylinder 186 for release or insertion of the work. Sequential operation of the apparatus is obtained through limit switches 194, 196, 198 actuating solenoid valves controlling the cylinders 74, 186. The parts may be cold rolled or induction heated and the teeth on the platen may have inclined pitch lines or may gradually increase in height so that the impression made in the workpiece gradually increases as the operation proceeds.
