Abstract
1,141,061. Forging manipulators. DAVY & UNITED ENG. CO. Ltd. 25 Feb., 1966 [2 March, 1965; 3 Jan., 1966], Nos. 8901/66 and 124/66. Heading B3H. A forging manipulator wherein the carriage moves continuously during forging, has its peel connected to a single-acting piston/cylinder assembly which restores the peel to its datum position when the forging is released. The peel 17, Fig. 1, is connected to a cylinder body 15 containing a piston-rod 12 secured to the manipulator carriage 14. Slidable upon rod 12 between shoulders 55, 55a is a piston 43 which also slides in an enlarged central part of the cylinder between abutments 45, 45a. Cylinder port 47 is connected to exhaust and cylinder port 48 may be connected to a pressure liquid source by means controlled by the forging tools. An annular projection 50 on the piston enters cylinder end bore 21 for cushioning the end of the piston stroke, Fig. 3 (not shown); stops are 60 provided on the opposite end of the piston. The manipulator is operative when forging in either direction. In a modification the right-hand side of the piston may be open to pressure continuously, for biasing the peel to its datum position, and work in conjunction with an accumulator. Other embodiments are described, Figs. 6, 7, 8 (not shown), using two pairs of parallel cylinder assemblies (64), (65) containing pistons (67), (68) connected respectively to the peel and the carriage. Hydraulic control systems are described. In a further embodiment, Fig. 9 (not shown), three parallel cylinders are used. The manipulator may also provide vertical movement for the workpiece. Reference has been directed by the Comptroller to Specification 898,738.
