Definitions

  • ABSTRACT The disclosure of this invention relates to a combined uncoiler-coil device employed in the rolling mill industry for feeding coils of metalic strip to the mill.
  • the uncoiler-coil box disclosed includes a pair of cooperative but independently moving opposed mandrels and disks, the mandrels passing into the opening of tight coils for rotatably supporting and feeding them to the mill, while the disks are caused to engage the sides of loose coils to restrain the coils while being fed to the mill by a pair of driven rotatable rollers arranged between the disks and below the coil.
  • the device also includes a single equalizing screw shaft mechanization for the disks which controls the opposed movement thereof.
  • the present invention also provides an equalizing device which can also serve as a drive for strip feeding machines or other devices, for example, machine tools having opposed members that must move towards and away from each other.
  • a further object of the present invention is to provide a coil strip feeding means having a single means for controlling the equal displacement of the opposite coil engaging members, which means is arranged in a non-obstructing location relative to the side which receives the coils being brought to the feeding means.
  • a further object of the present invention includes a single high'pitched interconnecting equalizing shaft having opposite threads on each side in engagement with the opposed frames for carrying the disks of a coil box or the cones of an uncoiler, in which construction the shaft is always placed under a tension force during the movement of the frames.
  • Another object of the present invention is to provide an uncoilercoil box including opposed frames for rotatably carrying the mandrels of the uncoiler and opposed frame for rotatably carrying the disks of the coil box, screw shaft means arranged on the side opposite the entry side of the combined uncoiler-coil box, a pair of nuts mounted in each coil box frame threadably connected to said said screw shaft means, means for restraining said nuts from rotation so that they will be caused to traverse along said screw shaft means and cause rotation of the means, thereby to equalize movement of said opposed coil box frames, and means for moving said frames of said uncoiler towards and away from each other.
  • FIG. 1 is a plan view of a combined uncoiler-coil box machine incorporating the features of the present invention
  • FIG. 2 is a sectional view taken. on lines lI-ll of FIG.
  • FIG. 3 is a sectional view taken on lines III-III of FIG. I.
  • FIG. 4 is a sectional view taken on lines IV-IV of FIG. 1.
  • FIGS. 1, 2 and 3 there is shown a combined uncoiler-coil box 10 in which it is important to note, as indicated by the arrow in FIG. 1, that the coils move from the left to the right of the figure. It should also be noted that both sides of the combined machine are identical and many of the components and functions are well known in the industry which, for brevitys sake, will not be described in detail.
  • FIGS. 1 and 2 show the pair of piston cylinder assemblies 21 and 22 for the frames 11 and 12, respectively, which are connected to the frames, as shown in FIG. 2, by clevises 23 whereby, on operation of the cylinder assemblies 21 and 22, the frames are advanced toward and away from the imaginary centerline that separates the opposed units.
  • each frame the pair of guide rods 13, 14 are tied together by a shaft which carries a pair of pinions, one of which is shown at 61in FIGS. 2 and 3.
  • Each pinion 61 meshes with a rack 62 secured to an associated rod 13 and 14. As a result, the movements of the rods of the sameframe are equalized.
  • the frames include bearing assemblies 24 for rotatably supporting disks 25 and 26 in a manner that while the disks are nondriven they are allowed to rotate freely with the coils after being brought into engagement therewith by operation of the piston cylinder assemblies 21 and 22.
  • each frame rotatably supporting non-expandable mandrels 33 and 34.
  • the frames 31 and 32 in clude nonrotatable shafts 37 which are supported by yokes 38.
  • the shafts 37 carry bearings 39, the outer races of which are secured to the mandrels 33 and 34.
  • the opposed ends of the yokes 38 have projections 41 received in U-shaped guides 42 that are formed on stationary upright members 43 that, in turn, form part of the base 17.
  • the entire assembly fits into the opening formed in part by the cross-over members 11a and 12a and are moved relative thereto by piston cylinder assemblies 35 and 36. As shown in FIGS.
  • the piston cylinder assemblies 35 and 36 midway between their opposite ends are secured to a base 63 by trunnion brackets 64, the base 63 being secured to the frame 17.
  • the base 63 being secured to the frame 17.
  • FIGS. 1 and 4 Arranged at the side opposite the side where the coils are brought to the strip feeding device, as best illustrated in FIG. 1 by the arrow, there is provided a threaded shaft 45 having left and righthand threads on end portions 46 and 47. The threads are formed with a very steep pitch of the order of approximately 45 and hence are non-locking. The opposite outward ends of the portions 46 and 47 are provided with bushings 48 and 51 supported in the frame 17.
  • replaceable keys 57 which are adapted to fit into one of the spaced openings 58 formed in the nuts. This allows relative adjustment below the frames 11 and 12. Once the desired positioning has been accomplished, the keys will be inserted into the adjacent openings 58 so as to lock the nuts against rotation in the encasement members 54 and 55. It is also important to note that, on operation of the cylinder assemblies 21 and 22 to advance their respective frames 11 and 12, this motion when transferred to the shaft 45 subjects the shaft, by reason of the clearances 50, only to a tension force, thereby obtaining the advantage of minimizing the diameter of the shaft. As indicated in FIG. 1, not only does the present invention allow elimination of any ties on the entry side of the unit, but it also provides a very simple and compact arrangement for equalizing the motion between the two frames 1 l and 12.
  • equalization of theuncoiler frames 31 and 32 and, hence, the mandrels 33 and 34 is accomplished hydraulically in a well-known manner, not shown.
  • the mechanical equalizing means in the form of a screw shaft 45 can be provided for equalizing the movement of the mandrels.
  • the screw shaft 45 in a given case, can be located in several other nonobstructed positions with reference to the coils being brought to the machine; for example, the shaft can be located beneath the machine on the center line thereof.
  • each frame including members for engaging opposite portions of a coil position between said frames
  • a power means for at least one of said frames connected thereto for moving said one frame towards and away from said other frame
  • bearing means carried by said supporting means for rotatably supporting the opposite ends of said shaft
  • said coil engaging means includes,
  • each of said other frames is carried by opposed upright members supported by said supporting means
  • first frames carried by said base member, said first frames having an inverted U-shaped structure
  • first power means for moving said first frames towards and away from each other
  • said disks having openings for allowing an adjacent mandrel to pass through
  • second power means for moving said second frames towards and away from each other and relative to said first frames.
  • said first power means including a pair of spacedapart piston cylinder assemblies for each first frame
  • a pinion for each pair of racks interconnecting the racks of a pair to equalize the movement of the piston cylinder assemblies for each first frame.
  • bearing means carried by said shafts for rotatably supporting said mandrels.
  • each first frame comprises two spaced-apart sets of bearing blocks
  • each frame including a cross-over member extending between one of the bearing blocks of each set
  • each of said second frames comprising upright members arranged in said openings and supported by said base member
  • bearings carried by said shafts for rotatably carrying said mandrels.
