Definitions

  • This invention relates to wire ropes and the method ot the invention may be applied to strands, steel cores and/or finished or partly finished rope, irrespective of the type of core used or whether the ropes are stranded or locked coil.
  • the invention is more specically, but not solely, applicable to steel wires which have been isothermally quenched (bringing them into the condition known as patented) and then cold drawn, It is also applicable to constructions in which, say, liller wires which have not been isothermally quenched, are incorporated into a strand or core, the other wires of which have been isothermally quenched.
  • strand as used throughout the specification and claims is meant a combination of steel wires arranged around a central, or king wire, in one or more helically wound layers, each layer of wires having a specific lay length.
  • the invention consists of a method of treating steel wire strands, cores or ropes, by imparting thereto a controlled degree of plastic ow with uniform pressure all round.
  • FIGURE 1 is a cross-section of a 6/1 wire strand, prepared in accordance with the invention, with the strand in the untreated state indicated in phantom.
  • FlGURE 2 is a similar View of a 9/9/1 strand.
  • FIGURES 3 and 3a show a plan
  • FIGURES 4 and 4a a side elevation of an apparatus for carrying the invention into eect.
  • FIGURE 5 is a cross-section of a 6/1 strand illustrating a correct drafting A, with two phases of insufficient drafting B and C
  • FIGURE 6 is a cross-section of a 12/6/1 strand prepared in accordance with the invention.
  • FIGURE 7 is a cross-section of a 12/6/1 strand with filler wires, prepared in accordance with the invention.
  • FIGURES 8, 9 and l() show diagrammatically, alternative apparatus layouts for carrying out the invention.
  • the basis of the preferred method of operation is the application of the combined resultant reactive force arising ⁇ from plastic iiow under compression, coupled with predetermined elongation of the strand, whilst passing through a die of tungsten carbide, hardened steel, ceramic or any other material capable of acting as a drawing medium.
  • Back tension is applied to the longitudinal axis of the strand as it passes to the die, of sufficient magnitude to initiate plastic flow prior to the strand entering the die,
  • each outer Wire cross-section is a pentagon, as illustrated in FIGURE 2. That is, the king wire becomes faceted according to the number of wires laid over it, the point of Contact of the next layer of overlying wires forming the base of a pentagon which abuts a corresponding facet on the polygonal king wire, the next layer being of reversed pentagons and so on.
  • the steel wires which may be round wires in the plain state, galvanized or treated with any other form of anti-corrosive or anti-frictional agent, are laid up into the desired construction in a stranding machine, the strand so ⁇ formed being coiled on to a reel, preferably of steel or light alloy.
  • MACHINE SET-UP In the arrangement of FIGURES 3, 3a, 4 and 4a, the reel 1 of the strand is inserted into the cradle 2 and the end taken through the fairlead 3. From thence it is led three times around the capstan wheel 4, forward again through the cooling unit S, then into the die 6 and finally on to the second capstan or surge wheel 7, where it is allowed to lap round until the surge pad is full, thus attaining maximum traction. From there it passes through a second fairlead 8 on to the take-up drum 9 and over traversing gear 9a.
  • the strand and the face oi the die Prior to passing into the die, the strand and the face oi the die are supplied with a copious stream of lubricant by means of a centrifugal pump 10; the lubricant then gravitates back to the return tank 11.
  • the die 6 is watercooled, and it is advantageous to ft a snorter on the strand as it emerges from lthe Idie as a high degree of follow-through of the lubricant takes place.
  • the die-holder 12 of the die ⁇ 6 is tted on a swivel in the horizontal plane, and can be moved by quadrant and worm 13 by handle 13a so that when required, kill can be imparted to the strand.
  • Additional control may be obtained by employing any hydraulically operated recorder on the friction brake 15, also by la similar type of recorder behind the die, which can be used to record the ⁇ actual back tension in the strand.
  • the requisite deviation of the die from its longitudinal axis is then set by the worm and quadrant 13, and the machine is opened up to full speed.
  • Rotation of the cradle 2 can -be effected las desired by means of the power drive 16 over the gears 17, and the reel 1 is braked by means of the lfriction brake 18 with brake band tension 19.
  • the main advantage is that a considerable reduction in the horse power required to draw the strand through the die is effected, particularly when the die is revolved ⁇ at high speeds, in the order of 4,000 to 5,00() rpm. Further advantages are, that the life ⁇ of the die is prolonged due to the prevention of uneven wear of the effective drawing portion of the die, that ovality of the strand reduced, coupled with better follow-through of the lubricant used whilst drawing.
  • a toothed driving wheel is built in as an integral part of the chuck, .and geared lto a high speed motor, which imparts the required rotation to the chuck in either a clockwise or anti-clockwise direction.
  • the jaws of the chuck are closed until the diameter between the roller faces the final diameter at which it is required to produce the strand. They are then locked in this position, and the tapered end of the strand fed through as in the case of a die, to the pullingin strap, and the chuck rotated at the requisite speed, with the lay of the strand.
  • the strand is then pulled forward through the rotating chuck, thus .attaining the requisite degree of drafting and internal geometric pattern in the individual wires.
  • Any method which will produce ⁇ a graduated taper at the end of the strand to allow its insertion into the die can be employed such las twisting the end of the strand While it is hot and then grinding Vto the requisite degree of taper; or alternatively by svn-aging.
  • the free end of the strand is inserted into the die until a sufficient length is available to .allow a pulling-in strap
  • the machine can then be operated until a sufficient length of strand has been drawn through the die to permit of lapping around the haul-off capstan, and on to the take-up reel.
  • vAs soon as the initial lengthkof strand has been run through the machine, as described above, and secured to .the take-up reel, the die box is set to the requisite angle with the quadrant control, and the necessary back tension applied -via the brake band on the first capstan near the pay-off reel. All the necessary factors are now under control, according to the pre-set conditions, and uninterrupted drawing can proceed.
  • the dies are conveniently :orthodox wire drawing dies of conventional pattern, made of tungsten carbide, and runs vofwell over .a ton with such dies, employing a 27% drafting on 10G/110 ton tensile material in the outer wires l ave ⁇ been successfully accomplished, without any deterioration of the die surface, and with the special lubricant used, fthe die should remain on size.
  • the lubrication is basically a highly refined mineral oilinto which additives have been incorporated to give:
  • the lubricant is one which is intended not only to enable the drawing to be done with maximum efficiency
  • section A FIGURE 5 we have the correctly compacted geometric shape attained by the optimum drafting. Failure to apply the requisite optimum drafting will result in cooking of the outer wires and tubing of the outer cover, the varying degrees depending upon the percentage drafting, with the formation of a bird-cage when drawn.
  • section B FIGURE 5 we have a ⁇ case where too light a drafting has been employed and, under such circumstances, the outer wire has been unable to compress the king Wire, and consequently, is expanding to ran ellipse, with resultant tubing of the cover, or lifting of the outer wires away from the king Wire; the wire deforma- -tion then becomes inconsistent and finally a wire lifts right out and the whole strand bird-cages and malforrns.
  • section C FIGURE 5 an intermediate phase is demonstrated; this takes place when a drafting lying between the correct one and one that produces the result described in the previous paragraph, is applied.
  • the wire is plastic-ally deformed to the requisite geometric shape, but is unstable upon its axis and it tilts tangentially to the circumference of the strand, producing two convergent planes on the crown or contact position ofthe outer wires.
  • the line D-E illustrates the .tangential flat which is produced on the surface of the individual Wires when an insufficient degree ⁇ of drafting has been employed. Consequently, in the wire marked C, instead of having a uniform radius on the external surface, or drawn position, a tangential flat is formed. This causes the deformed wire to tilt upon its 'axis and give the appearance of a worn strand, instead of allowing the wire to correctly defo-rm to its full geometric pattern and secure complete locking in the strand.
  • reference 3x refers to the continuous black line at the base of the correctly formed wire at A and shows how, as a result of the king wire being faceted, the overlying wires have a correspondingly firm base upon which to rest.
  • oval section B cannot form a flat surface, but a spessi? slightly concave depression, which allows of rolling or rocking of the wire about its axis on the king wire, instead of its being firmly seated.
  • FIGURE 6 shows the 12/6/ 1 construction cross-section without ller Wires, after drawing, ⁇ and shows that the wires of the intermediate layer ⁇ between the king wire and the outer wires become pentagonal.
  • FlGURl-E 7 shows the eifect of iiller wires (ie. the small diamond shaped wires) which add an extra side to the pentagonal shaped Wires over the king wire, also an extra side to the outer wedge shaped wires.
  • iiller wires ie. the small diamond shaped wires
  • any combination of iiller wires interposed between the round wires produces the diamond shape in the filler wire with the corresponding extra side on the pentagonal shaped wires.
  • the full geometric pattern is attained, and the air space within the strand has disappeared.
  • the strand has virtually become a solid bar proved by the modulus rising rapidly to a close approximation to the modulus of a solid steel bar.
  • the back tensioning force will range from, say, 12% to 35% of the breaking load of the strand.
  • the back tension can be measured by means of any lydraulically operated recorder incorporated behind the TYPES OF STRANDS
  • the process and equipment as described has dealt with the treatment of strand Where round wires have been concentrically disposed around a king wire.
  • triangular or oval-sectioned dies for a round one, and the building up of suitably constructed strand to allow ofY geometric reorientation, flattened, triangular or oval strands of any desired degree can also be produced with the same equipment and basic principles.
  • the method is applicable to armoured or independent wire rope cores, also to strands whose cores are composed of plastic, either in the -form of a solid rod or containing a conductor, when improved fatigue resistance results.
  • the completed rope may then, if desired, be passed through a die in a similar manner, thus a controlled degree of plastic flow is imparted to the crown of the strands with uniform pressure all around the circumference of the rope.
  • FIGURES 8, 9 and 10 of the accompanying drawings Alternative layouts for treating strand in accordance with the invention are shown in FIGURES 8, 9 and 10 of the accompanying drawings.
  • FIGURE 8 the strand on a pay-off swift 20 is drawn in exactly the same way as steel wire, except that the die 21 is not only water cooled but immersed inthe lubrieating medium in oil bath 22 and the strand before ventering the die passes around pulley 23 which is fitted with a braking device (not ⁇ shown) to ⁇ give the necessary back tension.
  • the strand after drawing is taken up on the drawing block 24.
  • the st-rand is then lapped three or four times around the drawing block '25, led' through a lubricating bath 22 and die 21 on tothe second drawing block 2 6.
  • the two blocks and 26 are driven by variable speed motors and to attain the necessary back tension the drawing block at 25 is runat a specified number of revolutions per minute slower than block 26. This allows the initiation of lplastic flow under controlled conditions, 'prior to the strand entering the ldie 21.
  • the strand comes ot the pay-off swift 20 over the capstan wheel 27 which is fitted with a braking device to apply back tension and is situated vertically over the haul-ofi capst-an at 28.
  • 'Ihe die 21 and lubricating Ybath 22 are situated between the two capstans 27 and 28. From thence the strand progresses forward on to the haul- -olf reel 29.
  • the final form is th'e same as that obtained by pulling through a die, it is produced by the combined resultant reactive force arising from predetermined elongation of the strand, whilst subjected to vrapid cyclic compression around the circumferenceof thestrand by mechanical means, using segmental dies, i.e. swaging. 4 g, l
  • Both the strands, and consequently the finished rope have a smooth surface, and as a result are easy to handle, the above factors again adding to the fatigue resistance, due to the fact that the surface layer of the strands has been plastically flowed, and the notch sensitivity of the component wires reduced.
