Definitions

  • the tension or-stress applied'to'the wire is'equivalent to that which is sufiicient todraw the' wi're through adie which reduces itsdiameter and is-approximately-25-90'% of the tensile .strength of the wire.
  • Other-Wire redhcihg means such as a pair of grooved rollers may be'subs'tituted for the die but it is noted that-the stress applied by a die is not only of the desired degree but it is also "av'ei'y uniform one.
  • the contact with'the' electrodes' is avoided by placing the anode and the cathode of thefgenerator in two separate baths such as an electrolytic cleaning bath and the electroplating ba'th "wher'eby the-current passes from the anode in the plating baththroughthe-said bath along the wire, and through the cleaning bath to the cathode in the said cleaning bath without'direct contact between the wire and the electrodes.
  • Fig. 2' is a -top plan view 'of the apparatus of Figs. 1A wand '1B-:'wi'th some-of the baths omitted.
  • iEig. 3 is a-Iletail view partlyin cross section ofone lbatlv'with its-liquidcirculating system.
  • Fig. 4 is-a detail view-of a typical drawing die.
  • a guide roller or-sirnilar "guide Jmeans -could be inserted between the die 10 and rthe first-bath.
  • Adjacent 'eaeh of -the slitted ends of the bath structture is a 'trough 43 or '44 adapted to catch the bath liquid which flows throughsaid -slits 41, 42.
  • the other baths 30, '40, 50, 60, 70,80, are constructed similarly to bath 40.
  • the bath 20 contains electrodes .29, 29-and the bath 60 contains electrodes 69, "69 which ado,notjcome into-.directicontact with:the wires.
  • the elecutmdes are eonnectedito a commonsource of direct curnl'qn ii61 l shown-in F s Simetthetwirerl0ll passesifrom the die 10 to thetguide roller 12, for example, in a substantially straight horizontal path and since the wire is under a very large tension which is great enough to draw the same, the said wire may be caused to vibrate all along the length between the die 10 and guide roller 12 by intermittently striking the same.
  • One difliculty in plating wires is to obtain the desired rate of deposition (measured in amperes per square foot and expressed as current density,
  • the limitation on current density is determined by the speed with which the ions in the plating solution can be replaced or recreated adjacent the cathode for deposition on the latter.
  • the c rinveiitional way of improving this condition is by agitatingthe solution, by mechanically holding and vibrating the cathode or by a combination of :both such means.
  • theplating. operation is carried. out 5 while the wire is under a high constant tension suflicient to draw said wire.
  • This invention isbased on the discovery not only that sucha process is feasible'dO but that it has at least one added advantage, namely, that while under such tension the wire, may be made to act as its own vibrator.
  • the wire when struck acts like a violin string.
  • the striking mechanism 90 for causing the wire 100 to 'l5 guide rollers or other means contact the wire between" the die 10 and guide roller 12.
  • the striking mechanism shown consists of a disk 91 held on rotating shaft 92.
  • the disk 91 carries one or more fingers 93, 94 which move from a position below the line of travel of the wire 100 to a position above the line of travel so. that each finger 93, 94 strikes'the wire during each rotation.
  • the shaft 92 is driven by suitable means such .as pulley 95 and belt 96.
  • the tension required to hold the wire at its entrance end so that it can be vibrated according to the invention is possible only through a device capable of deforming the wire such as the die 10, oran equivalent means.
  • the wire could be vibrated by other devices such as by electromagnetic means, etc.
  • the current density has been increased to many times that which is possible without such vibrating step. For example, current densities as high as 3000 amps per square foot have been employed as compared with a maximum of about 200 amps per square foot ordinarily employed.
  • the exact nature of the die 10 is not important as long'as the die 40 is capable of holding the wire under sufficient tension. Fig.
  • FIG. 4 shows a conventional type of die 10 having an orifice 11 which can be employed.
  • a plurality (four shown) of wires 100 may be treated simultaneously the guide rollers 12, 13, 14 and 15 and take-up rollers 16, 17, 18 and 90 being offset with respect to each other.
  • the wire 100 can be of any suitable size and subsequent to plating, it maybe redrawn to smaller diameter since the plating which is applied at a relatively high current density is very uniform and is very adherent to the base material.
  • Example A .045" copper wire is drawn through a die 10 to reduce its diameter to .042" 'by an apparatus like that shown in Figs. 1A, 1B and 2 and drawn through a series of baths 20, 30, 40, 50, 60, 70 and 80.
  • the speed at which the wire is pulled through the baths is from 3 to 200 feet per minute.
  • the wire is cleaned with an electrolytic cleaning bath such as a batlr-of sodium phosphate at 180 F.
  • Inbath 30 the wire is rinsed,- in
  • bath 40 it is dipped in 10% sulfuric acid, in bath 50 itisag'ain rinsed, 'in' 60 the wirebecomes the cathode and is plated with tin from ya tin plating bath, in bath the wire is again rinsed, at 90 the wire is periodically struck to cause it to vibrate and in bath the wire is given a hot water rinse to cause it to dry quickly before winding.
  • the wire is drawn off and wound at 16. Thereafter the wire may be drawn down to a diameter of--.0ll" in twelve steps.
  • an apparatus for electroplating wire comprising a series of baths including an electroplating bath horizontally arranged in substantially the same horizontal plane, a die adjacent a first end of said series of baths, means for feeding wire to said die, said die being-of smaller size than said wire whereby said die is adapted to resist movement of the wire therethrough, means adjacent the other end of said series of baths adapted to apply sufficient tension to the wire to draw said wire through said die, the horizontal path between said die and said wire drawing means being substantially unobstructed whereby the wire passing in said unobstructed path is electroplated while under a substantially uniform drawing tension, said baths having parallel slits at the ends thereof for the passage of said wire therethrough and means adjacent one of said baths of said series adapted to set the wire to vibrating in the direction of the slits in said baths under the natural vibration frequency determined by the tension on the wire and the distance between said die and said drawing means whereby said vibrations extend along the entire horizontal path between the die and the drawing means.
