Abstract

928,708. Rolling annular bodies. SVENSKA KULLAGERFABRIKEN A.B. Dec. 18, 1961 [Dec. 17, 1960], No. 45233/61. Class 83 (4). A rolling mill for working annular blanks comprises a pair of aligned rolls, each roll having an ejector piston movable in it, the pistons being coupled to move together so that as one piston moves in to load its roll the other ejects a finished rolled blank. The rolling mill comprises a carriage 4 mounted on a shaft 9 having eccentric piston extensions 10 slidable in cylinders 12 of a frame 15 and an hydraulic control valve 19 which permits oil to enter one of the cylinders to move the carriage in the desired direction. The carriage houses a journalled carrier 2 having external driving belt grooves 5, cylindrical die members 1 and pistons 6 slidable in the die 1 and mounted on each end of a shaft 7. On loading, a blank 14a is placed on a roller 8 rotatably journalled in the frame 15 and the carriage 4 moved in a direction A by the hydraulic piston 10 so that as the die 1 moves over the blank the piston is moved in the opposite direction to eject the finish formed blank from the opposite die. During the rolling operation the carrier 2 is driven and the eccentric shaft 9 is gradually rotated about the axis of the pistons 10 by means of a gear train 24, 25 to lower the carriage on to the roller to produce the required finish blank size. Excess material may by removed by a cutting tool 16a mounted on the inside face of the frame.
