Definitions

  • This invention relates to a method for cleaning an elongate strip and in particular to the cleaning by abrasion of the surface of metal wire, rod or strip so as to remove for example oxide following a heat treatment operation, or lubricant following a rolling or drawing operation.
  • a method of cleaning an elongate strip comprises passing the strip through an apparatus which applies vibrations to the strip and is characterised in that the strip is under tension between two points separated along the length of the strip, the strip passes through dies dimensioned to create a working clearance about the strip which dies are also axially separated but disposed between the said points, causing actual transverse movement of the strip so that a number of points around the strip contact the dies, and passing a fluid through the dies, and passing a fluid through the dies to displace the material removed from the strip surface.
  • the invention also consists in apparatus for carrying out the method.
  • the invention differs from the prior art in that essentially the workpiece is vibrated, the workpiece must be under tension, and the removed material is flushed out of the dies by the fluid.
  • the die will have a cylindrical bore, and the same bore will be used as a passage for the fluid which is to displace material removed from the strip surface, and the fluid, which conveniently is water, may be pumped under pressure through a tangential opening to a midpoint along the length of the bore so that the water tends to spiral in opposite directions to the ends of the bore.
  • the fluid which conveniently is water
  • the strip may be vibrated transversely by mechanical means or by electromagnetic means for example.
  • the vibrations may be applied to the strip whilst passing through a relatively stationary die structure, or alternatively the die structure may be subject to the vibrations so as to displace the strip laterally and hence cause the vibration in the strip.
  • the wire may pass over a rotating pulley having its surface formed somewhat as a snail cam so that the wire is displaced laterally and then allowed to return due to the tension in the wire.
  • a number of such means for causing the lateral displacement may be provided arranged for displacement generally at right angles to one another.
  • the preferred direction of vibration of the strip is in a generally circular pattern extending about the axis of the tensioned strip when not subject to the vibration.
  • a number of cleaning dies are provided, at suitable intervals, along the length of the strip and where mechanical or electromagnetic means cause the lateral movement of the wire, the force causing the vibration may be applied at points betwee successive dies so that the dies tend to act as nodes or at least as points of minimum amplitude of vibration with the maximum amplitude being at the points of application of the force causing the vibration.
  • a rotating magnetic field may be set up for example at each die, and it is believed that this may be useful not only with magnetic materials as the strip but also with good electrical conductors as strip, and hence in practice with substantially all metal strips which are required to be cleaned.
  • the invention is applicable to strips which are not of circular cross section, for example rectangular strips.
  • the die will also be of similar rectangular section.
  • the dies may be made of a material selected according to the nature of the cleaning operation to be carried out, and according to the nature of the strip material.
  • cleaning oil from a soft material wire may be achieved using a high density polyethylene for the die, but if a fierce abrasive action is required to remove stubborn scale, a tungsten carbide material may be used for the die surface.
  • cleaning can include removal of contaminants such as the lubricating oil mentioned, removal of surface oxide, and also include the possibility of including polishing or other surface finishing of the strip material with such removal of lubricants, scale and the like, or if the wire was chemically clean before the treatment, (which is an unusual situation) then it includes the possibility of performing a surface finishing or polishing operation per se.
  • the rod or strip 10 is conveyed in the direction of the arrow A under tension.
  • it may be driven by pairs of pinch feed rolls 12 and 14 of which the rolls 12 run slightly faster than the rolls 14.
  • the rod passes through two cleaning dies 16 which are generally similar to one another, each of which has a bore slightly larger than the rod and of the same cross section.
  • the drawing exaggerates the clearance in the interest of clarity in explaining the manner of operation.
  • the rod is vibrated transversely and generally in a plane containing the axis of the rod by the use of a snail cam 18 which is rotated about the axis 20 and which engages the rod at its periphery substantially midway between the dies.
  • a snail cam 18 which is rotated about the axis 20 and which engages the rod at its periphery substantially midway between the dies. This causes the rod to oscillate generally between the two extreme paths indicated by the chain dot lines 22 and 24, the oscillations being continued between nodal points at the respective pinch rolls 12 and 14 and being limited by the dies.
  • the rod By imparting vibration about a second axis at right angles to that of shaft 20, the rod can be caused to vibrate in a generally circular pattern within the bounds indicated by the chain dot lines 22 and 24 with increased certainty of cleaning of the entire surface area.
  • Material abraded from the rod surface in the dies is flushed by liquid pumped through the pipe system 26 and, in this embodiment, the pipes lead to tangential apertures in the die bores so as to cause a spiralling current of cleaning liquid to flow through the bores.
  • the rod may be dried for example by an air wipe constructed generally as described in GB-A-533846.
