Definitions

  • the field of this invention is the cladding or coating of wire or rod made of steel or of steel alloy with a nonferrous metal, and in particular a new method of applying such overlay of a substantial thickness by mechanical means and without heat.
  • This invention solves the old problem of covering or cladding of a steel (or steel alloy) wire in a continuous process by mechanical means only, by which process an inseparable molecular bonding between the steel wire and the overlay is achieved, and by which process a final calibration of both the steel wire and the thickness of the overlay is attained, without complicated preparatory treatments.
  • Another object of the invention is to provide a method of applying substantially thick overlays on steel or steel alloy wire.
  • Yet another object of this invention is to provide a new method of mechanically molecularly bonding of a substantial overlay of a non-ferrous metal on a steel or steel alloy wire.
  • a further object of the invention is to provide a method of attaining a finished product by simultaneously reducing both the diameter of the steel or steel alloy wire and the thickness of the overlay in one final step.
  • FIG. 1 shows in a schematic manner the loose application of the overlay sleeve and the adaptation thereof on the steel wire;
  • FIG. 2 shows the final step of bonding and reducing of the diameter of the product
  • FIG. 3 shows the combination of the two steps into an in-line production.
  • FIG. 1 a schematic illustration of the first step of the method of this invention and of the apparatus for this operation.
  • the steel (or steel alloy) wire 11 is propelled by a pair of conveyor rollers 12, 13.
  • a tubular sleeve 14 made of the overlay metal is loosely slipped over wire 11.
  • This tubular sleeve may consist of a suitable metal, such as lead, aluminum, copper, soft brass or the like. Both sleeve 14 and wire 11 are forwarded into a first die block 15 whereby the diameter of sleeve 14 is reduced in a first step to fit more closely around steel wire 11.
  • tubular sleeve 14 and wire 11 are drawn through the second die block 16 whereby tubular sleeve 14 now is closely fitted around wire 11.
  • a pair of pulling rollers 17, 18 are arranged after the die blocks 15, 16 for drawing the wireoverlay combination through the dies and for conveying the obtained intermediate product 19 to a storage spool 20.
  • FIG. 2 shows the second step and the necessary equipment for performing the final operation.
  • the intermediate product 19 is fed from storage spool 20 (not shown in the figure) into an elongated drawing channel 21 which may best be characterized as a stabilizing die.
  • This stabilizing die holds the overlay over a fixed length. In this die, it is not possible that the form of the product can be modified, while the length of this stabilizing die channel is sufficient to increase artificially the friction resistance between the steel wire and the overlay in such manner as to prevent slipping or stripping of the overlay when the product will be reduced and calibrated in the final die as one element.
  • FIG. 3 which also shows the final pair of drawing rollers 23, 24 which are arranged at the end of the production line, and which convey the final product to the receiving spools (not shown in the drawing).
  • a steel wire which is to be coated may have a diameter of 3.6 mm.
  • a lead tube having an inside diameter of 5.5 mm. and an outside diameter of 7.5 mm. is slipped over the wire.
  • Drawing die block 15 has a drawing diameter of 6.5 mm., a lead-in angle of approximately 6 and an actual draw length of 2 mm.
  • a first reduction of the lead tube from 7.6 to 6.5 mm. is obtained, followed immediately by the second drawing die block 16 wherein a second reduction to 5.6- mm. outside diameter is achieved.
  • the inside diameter of the lead tube now is 3.6 mm. and thus closely fitting and adhering to the steel wire which has the same diameter.
  • the overlay now has a thickness of 1 mm.
  • the intermediate product is fed for the second and final step into the stabilizing die 24 wherein the overlay is prevented from being stripped off the steel wire due to the increased frictional resistance between the two metals.
  • the stabilizing die 21 has to be 70 mm. long and has an entrance cone of 17 opening angle.
  • the final outside diameter of the finished product after having passed through final die 22 is 5.2 mm. This indicates that an overall reduction of .4 mm. of the diameter had taken place, which is partly in the diameter of the steel wire, partly in the lead overlay, in'proportion of the different hardness of the two metals.
  • the dimensions of stabilizing die vary from case to case depending upon the thickness of the overlay and upon the hardness of both the wire and the overlay materials.
