Definitions

  • This invention relates to rolling machines and in particular to a drive mechanism for a machine for rolling metal plate into cylindrical form.
  • Conventional rolling machines comprise three rolls located, in section, on the apices of an imaginary triangle.
  • the upper roll is free to rotate, while one or both of the lower rolls are driven.
  • Such drive mechanisms are known and used in profiling machines where, however, only one driven and one dead roll, or two opposed driven rolls are involved.
  • a rolling machine is provided with at least one pair of driven rolls which are positionally adjustable with respect to the remaining roll, a drive mechanism comprising a worm wheel mounted on each of the driven roll and a worm driven by means of an external power source, the worm being mounted to remain in mesh with the worm wheels irrespective of the position of the worm wheels within the range of movement of the rolls.
  • the worm wheel is preferably maintained in mesh with the worm by the mounting of the worm with the axis of rotation thereof parallel to the adjustment travel of the part of the roll, preferably an end thereof, on which the worm wheel is mounted.
  • the machine comprises three rolls,two driven rolls located on a plane and one dead roll located thereabove the lower roll being driven by means of a single worm mounted with the axis of rotation thereof parallel to the plane in which the rolls are mounted, and the rolls being movable along the mounting plane for the positional adjustment thereof with respect to the upper roll.
  • each lower roll is adjustable along inclined planes and each lower roll is provided with a worm mounted with the axis of rotation thereof parallel to the plane of adjustment of the roll.
  • the rolling machine 10 shown in Figure 1 comprises a dead, or freely rotating upper roll 12 which is movable in a vertical direction (indicated by the arrow 13), and two worm driven lower rolls 14 which are movable in a horizontal plane (indicated by the arrows 16).
  • the worm wheels 14a are meshed with a worm 18 mounted with the axis of rotation thereof parallel to the plane of movement 16 of the lower roll 14.
  • the worm is driven by a motor 20, which could be any kind of a motor.
  • the roll 14 can be moved, within the range of the worm 18, along the plane 16 so that the position of the lower roll 14 with respect to the upper roll 12 can be changed.
  • the upper roll 12 can, of course, be moved up and down to produce the required bending moment.
  • the motor 20 is reversible so that the lower rolls 14, both moving in the same direction on the worm 18, can be reversed.
  • the machine 100 shown in Figure 2 differs from the machine 10 only in the fact that the adjustment travel of the lower rolls 102 ,is not horizontal but inclined upwardly towards the upper roll 103.
  • the worm wheels 105 associated with the rolls 102 are each provided with a separate motor 106 driving an inclined worm 108, each worm 108 meshing with a worm wheel 105.
