Definitions

  • Thi invention relates to opened coil annealing and more particularly to apparatus for supporting an opened coil for rotation about its axis during the recoiling thereof back into tight wound form.
  • the annealed opened coil is placed on an opened coil turntable and the outer end led to a mandrel on a tight coil turntable, the axes of both of said turntables being vertical, and the coil is rewound into tight coil form, suitable means being provided for imposing back tension on the strip approaching the tight coil turntable so that the desired tightness of winding may be effected.
  • FIGURE 1 is a diagrammatic plan view of an opened coil supporting turntable, a tight coil supporting turntable and an intermediate tension drum for establishing the necessary back tension to effect tight winding on the tight coil turntable;
  • FIGURE 2 is a vertical cross-sectional view through the opened coil turntable taken substantially in line 22 of FIGURE 1;
  • FIGURE 3 is an enlarged fragmentary cross-sectional view taken substantially on line 3-3 of FIGURE 1 and illustrating the spaced apart laps of an opened coil supported on my improved coil support and retaining means;
  • FIGURE 4 is a plan view of an opened coil turntable illustrating a modified form of my invention.
  • FIGURE 5 is an enlarged vertical cross-sectional view taken substantially on line 5-5 of FIGURE 4.
  • FIGURE 1 of the drawings an opened coil C is illustrated supported on the opened coil turntable T.
  • the laps 19 of this opened coil are spaced apart a distance somewhat greater than the thickness of the strip. It will be understood that such a coil is loose and has little inherent resistance to distortion in a direction normal to its axis.
  • the outer end of opened coil C has been led around the tension drum D to the mandrel 1 of the tight coil turntable T and a tight coil C is being formed thereon.
  • the turntable T as seen in FIGURE 2, includes a main coil supporting plate or disc 2 supported for rotation about its vertical axis on shaft 3 which in turn is mounted in suitable hearings in the base structure 4.
  • a coil centering mandrel 5 is concentrically supported for rotation with the turnt-a le T and extends upwardly above the upper surface thereof.
  • This mandrel may be of any suitable and well-known type and provides means for centering the opened coil on the turntable during both the coil opening operation and the tight coiling operation.
  • the tension drum D is mounted on a shaft 6 having a lower bearing support in a base structure 6' and an upper bearing support 7 carried by radially extending arms 8 which in turn are su tably supported from the base structure 6'.
  • the tight coil turntable T is suitably supported for rotation about its vertical axis and suitable means (not shown) are provided for driving and controlling the speed of rotation of the turntable T and the tension drum D.
  • a reversible variable speed motor M (see FIGURE 2) has driving connection to the turn-table T through the shaft 29 and suitable gearing (not shown) withinthe base structure 4.
  • the controller unitZf. in the power line 22 is adapted to control the direction and rate of rotation of the motor M and thus of the turntable T.
  • My improved opened coil retaining supporting turntable T includes a mat or pad 9 of resilient, yieldable, rubber or rubber-like material extending over substantially the entire surface of the turntable disc 2 and secured thereto as by vulcanization or bonding by any suitable means.
  • This pad 9 has its inner periphery at the mandrel 5 and its outer periphery substantially at the outer periphery of the disc 2.
  • rubber has been mentioned as a suitable resilient material, other rubber-like materials such as synthetic rubbers, plastics of various types, etc., may be employed, and where the term rubber is used in this specification and claims, it is intended to contemplate and include any resilient, yieldable, plastic type material.
  • durometer hardness is satisfactory when handling coils up to sixty inches or more in diameter of steel strip of twenty to fifty inches in width, it will be understood that for different sizes of coils and diiferent gauges and widths of material, the durometer hardness (which is a satisfactory measure of yieldability of the pad for purposes of this use) may be varied through a considerable range, for example between 50 and 70 durometer.
  • FIGURES 4 and 5 a modified opened coil supporting turntable T is illustrated in which the metal plate or disc 12 is provided with a plurality of circumferentially spaced radially extending rubber strips or pads 13. These radial pads may conveniently be mounted on the disc 12 by providing undercut grooves 14 in the upper face 12 of disc 12 and shaping the cross-section of the pads 13 to fit. It will also be noted that the upper faces 13' of the rubber strips 13 are disposed above the upper face 12' of the turntable disc 12 so that, when an opened coil is placed over the mandrel 1-5, the lower edges of its spaced apart laps will rest upon each of the series of spoke-like pads 13.
  • the weight of the coil will cause the lower edges of the laps to sink into the upper faces 13 of the pads 13 with resulting keying of the coil thereto as explained in describing FIGURE 3.
  • the weight of the coil may causethe lower edges of the spaced apart laps thereof to seat upon the upper face 12' of re disc 12, but the keying action which prevents lateral shifting of the laps under the influence of centrifugal force will still be effected because the pads 13 extend above the surface of the metal disc 12.
  • a turntable In apparatus for supporting opened coils of strip metal having spaced apart laps during recoiling thereof, a turntable, means for supporting said turntable for rotation about a vertical axis, controllable speed means for rotating said turntable, and resilient pad means secured to said turntable and having a normally flat depressible upper surface portion disposed to be engaged by and to support the bottom edges of the spaced apart laps of an opened coil of strip metal supported on said turntable and adapted to yield under the Weight of said coil whereby lateral movement of said laps during rotation of said turntable will be prevented.
  • a turntable In apparatus for supporting opened coils of strip metal having spaced apart laps during recoiling thereof, a turntable, means for supporting said turntable for rotation about a vertical axis, controllable speed means for rotating said turntable, and a resilient coil support pad of vertically yieldable material carried by said turntable and disposed to be engaged by the bottom edges of said spaced apart laps whereby material of said pad will extend upwardly between said laps and resist lateral movement of said laps on said turntable during rotation thereof.
  • a turntable In apparatus for supporting opened coils of strip metal having spaced apart laps during recoiling thereof, a turntable, means for supporting said turntable for rotation about a vertical axis, controllable speed means for rotating said turntable, a rubber coil support pad secured to the upper face of said turntable, the upper face of said pad being disposed to be engaged by the lower edges of the spaced apart laps of a coil on said turntable, and a coil centering mandrel concentric with said vertical axis of said turntable and rotatable therewith, said mandrel extending above said upper face of said pad.
  • a turntable In apparatus for supporting opened coils of strip metal having spaced apart laps during recoiling thereof, a turntable, means for supporting said turntable for rotation about a vertical axis, controllable speed 'means for rotating said turntable, a rubber coil support pad secured to the upper face of said turntable, the durometer hardness of said pad being between 50 and 70, and the upper face of said pad being disposed to be engaged by the lower edges of the spaced apart laps of an opened coil on said turntable. 7
  • a turntable In apparatus for supporting opened coils of strip metal having spaced apart laps during recoiling thereof, a turntable, means for supporting said turntable for rotation about a vertical axis, controllable speed means for rotating said turntable, and a plurality of circumferentially spaced, radially extending resilient coil retaining pads carried by said turntable and disposed to be engaged by the bottom edges of said spaced apart laps, the hard ness of said pads being such that material of said pads will extend upwardly between said laps of an opened coil disposed thereon and effect a keying resistance to lateral movement of said laps on said turntable during rotation thereof.
