Definitions

  • a conductor roll of the invention comprising a hollow steel roll body hav ing an outer surface covered with a chromium plated layer or a nickel-plated layer and an inner surface thereof covered with a copper layer electroplated thereon; a copper roll shaft including a flange shrinkage-fitted in said hollow body by using a heating and cooling technique in such manner that said flange contacts said plated copper layer, said flange being coupled to said shaft; and a sleeve, in which said roll shaft is titted and which has a flange coupled to said roll body.
  • a hollow roll body is coupled to a roll shaft, with the flange of the aforesaid roll shaft being shrinkage-fitted in the aforesaid hollow roll body by using heating and cooling technique.
  • the hollow roll body is heated to lOOC, while the flange of the roll shaft is cooled to -50C. Thereafter the roll and shaft are brought back to a temperature range close to room temperature.
  • the plated copper layer is formed intimately on the inner surface of the hollow roll body, there is no danger of the aforesaid defects, experienced with the conventional dual construction type cylindrical roll, such as clearance between the outer and inner roll cylinders.
  • the invention has the result that the electroplating current can be conducted in an improved manner from the metal strip via the copper layer to the roll shaft including the flange coupled to said shaft.
  • FIG. 1 is a longitudinal cross-sectional view showing part of the new conductor roll, taken along the axial line of the roll;
  • FIG. 2 is a modified detail view.
  • a conductor roll of the invention which comprises a cylindrical hollow steel roll body 10.
  • the roll body 10 has an inner surface which is copper-plated, thus providing a layer 2 of copper electroplated on said inner surface and thereby uniformly intimately bonded to all portions of said inner surface.
  • a flange 3 of a cop per roll shaft 4 is in contact.
  • the flange 3 is fitted in the hollow roll body 10, so that the hollow body 10 is electrically connected through copper layer 2 and flange 3 to the copper roll shaft 4.
  • a steel shaft sleeve 5 is provided on the roll shaft 4 and formed with a flange 6 which is coupled to the end portion of the hollow roll body 10.
  • this chamber should not be construed in a limitative sense, and hence the flange 6 may contact the other flange 3.
  • the hollow roll body 10 is fitted on the flange 3 of the roll shaft 4 by using a shrinkage-fitting technique by resorting to heating and cooling operations. For instance, the roll body 10 is heated to C, while the roll shaft 4 is cooled to -50C. Alternatively, the hollow roll body 10 may be welded to the flange 6 of the shaft sleeve 5. Still alternatively, the shrinkage-fitting technique may be used for coupling the flange 6 to the hollow body 10.
  • Hard electroplating such as for instance, hard chromium plating or nickel plating may be applied to the outer surface 8 of the roll body 10 and that of the shaft sleeve 5, including the outer surface of the flange 6, so that a hard, metallic, electroplated layer 9 may protect the roll body 10 from damage.
  • the sleeve is formed with a bearing portion 12 which rotatably supports the roll body in cooperation with another bearing portion (not shown).
  • an electric conductor ring 13, coupled with lock-nuts l4 and 15, is affixed on the end portion of the roll shaft 4, whereby electric current is introduced from the roll shaft 4 through a brush (not shown) in contact with the electric conductor ring 13 to external means.
  • the roll shaft 4 is adapted to rotate with the shaft sleeve 5.
  • the roll shaft 4 may be welded to the sleeve 5.
  • cooling-water passage 16 through the roll shaft 4 along the axial line thereof, with the exits of passage 16 being open to a cavity 17 in body 10, communicating with chamber 7 through apertues in piston 3.
  • the supply of cooling water through the aforesaid passage 16 may absorb joule heat generated in the roll body 10.
  • the right hand portion of the conductor roll is not shown in the drawing, but its construction is identical to that of the left-hand portion which is shown.
  • the drive means is not shown in the drawing, because it is well known to those skilled in the art.
  • FIG. 2 illustrates the portion of roll body 10 coupled to flange 3 of the roll shaft 4.
  • a silver layer 18 between the copper layer 2 electroplated on the roll body 10 and the copper flange 3.
  • the silver layer 18 is formed on the edge surfaces of 3.
  • the conductor roll according to the present invention may readily be manufactured. More particularly, after the plated copper layer 2 has been applied on the inner surface of the hollow roll body 10, the flange 3 of roll shaft 4 is shrinkage-fitted in the roll body 10 by using heating and cooling fitting technique. Then, the shaft sleeve 5 is fitted on the roll shaft 4 by introducing the sleeve from the end portion of the shaft onto the shaft. Thereafter the flange 6 thereof is rigidly coupled to the end portion of the hollow roll body 10. Thereafter, the outer surface of hollow roll body 10 is machined for centeralignment. Upon completion of such operations, hard chromium plating 9 is applied to the outer surface of roll body 10 as well as to the surface of shaft sleeve 5, at the same time.
  • plated copper layer 2 is applied on the inner surface of steel roll 10, while the flange 3 of copper roll shaft is shrink age-fitted in roll body 10 by using a heating and cooling technique so that the flange 3 contacts the plated cop per layer 2.
  • This plated copper layer 2 tightly adheres on the one hand to the roll body 10, and on the other hand to the flange 3 of roll shaft 4. This in turn ensures electric conductivity as high as that of the conventional solid type roll, while the material to be used therefor may be materially reduced.
  • the conductor roll of the invention may avoid difficulties and defects in electric conductivity such as are experienced with conventional dual-construction type cylindrical rolls.
  • a conductor roll for conducting electrical plating current comprising:
  • a hollow steel roll body having an inner surface and an outer surface
  • a copper shaft having a copper flange integrally connected thereto, which flange includes a silver layer in contact with the copper layer of said roll body to mount the flange of the shaft in said hollow body with firm electric contact between said copper and silver layers and said copper flange;
  • a hollow steel roll body having an inner surface and an outer surface
  • a copper roll shaft means fitted into said layer of copper to intimately contact said layerv 3.
  • a copper flange integrally connected to said shaft means and shrink-fitted to said layer of copper.
