Abstract

780,165. Angular bending. NEWSOME, J. July 7, 1955 [April 9, 1954], No. 10491/54. Class 83 (4). A sheet-metal working machine having a movable member 2 adapted to press against one side of the metal plate being operated on has such member operated by movement of a wedgeshaped member 6 transversely of the machine, the wedge-shaped member being mounted between the movable member 2 and a fixed member 7 provided on the machine, one of the tapering edges of the wedge-shaped member 6 and a correspondingly shaped surface on the fixed member 7, or on the movable member 2, forming a straight track between them within which are disposed a plurality of balls or rolls 17 or 8 which permit the transverse movement of the wedge-shaped member. The movable member or die 2 co-operates with a fixed die 1 and is guided in its vertical movement by rollers 10 in a housing 11 on the end of the die 2 running on a slideway 4. The wedge member 6 which co-operates with tapered surfaces on both the die 2 and fixed member 7 is moved by a piston 12 in an hydraulic cylinder 13.
