Definitions

  • a travelling or stationary manipulator having a tongsholder, with tongs, adjustable both in height and laterally, and also rotatable, for gripping and handling billets during forging, straightening and other deformation, the tongs-holder being slidably mounted upon two carrying members mounted parallel to one another in the lower part of a machine frame, and the carrying members being connected by ball-and-socket joints with the lower ends of four tie rods, the upper ends of which are connected by ball-and-socket joints with the lower arms of four bell-crank levers mounted fast upon two transverse carrying shafts, journalled in the machine frame, parallel to the two carrying members.
  • Means such as pistons and cylinders may be provided for a travelling or stationary manipulator, having a tongsholder, with tongs, adjustable both in height and laterally, and also rotatable, for gripping and handling billets during forging, straightening and other deformation, the tongs-holder being slidably mounted upon two carrying members mounted parallel to one
  • the tongs-holder of the tongs is supported, by four tension rods, journalled in balland-socket joints, suspended from the ends of bell-crank levers, each two bell-crank levers being secured upon one of two transverse shafts, rotatably supported in the machine frame or truck frame and extending transversely to the axis of the machine.
  • the object of the present invention is therefore to diminish the weight of the masses to be displaced, and to provide for the lateral fixing of the tie rods.
  • the lower carrying members are constructed as carrying shafts, upon which the tongs-carrier is slidingly displaceable.
  • the supports of the lower carrying members are advantageously constructed as resilient buffers. It is thereby made possible, without additional stressing of the tongs or the tongs-holder, to take up resiliently the lateral forces occurring during deformation.
  • FIGURE 1 is an end view, partly in section, of the tongs-holder suspended in a machine frame
  • FIGURE 2 is a side view in section on the line II-1I in FIGURE 1.
  • Spring buffers 10 arranged at the ends of the carrying shafts 6 are adjustable, so that the travel stroke of the springs, the spring tension, and the clearance between the ends of the buffers 10 and the side cheeks 11 of the machine frame can be determined.
