Definitions

  • the support frames were necessarily designed with large windows, resulting in a corresponding loss of rigidity which in turn rendered this arrangement undesirable for heavy-duty vertical rolling mills.
  • this necessitated excessive center to center distance between tandem roll stands to achieve the necessary horizontal clearances. needed to permit removal of the frame by an overhead crane or other suitable means.
  • Dismantling of the entering and delivery pass guides which extend a considerable distance on either side of the roll housing also became "ice necessary. Upon placing the new roll housing in position, excessive time was required to carefully re-set the pass guides in order to insure proper entrance and delivery of the stock.
  • the object of the present invention is to provide a vertical mill assembly in which the driving mechanism is advantageously mounted above a removably mounted roll housing arranged to facilitate replacement of rolls with a minimum loss of production time.
  • a specific object of this invention is to eliminate the necessity of a separate enveloping support frame for the roll housing, within which the rolls and chocks are positioned. This is accomplished by providing a more simple mounting which includes means for vertical adjustment and lateral displacement of the roll housing.
  • FIG. 1 is a sectional view of a vertical roll stand embodying the principles of the invention taken along 11 of FIG. 5;
  • FIG. 2 is a sectional view taken along line 2-2 of FIG. 4;
  • FIG. 3 is a sectional view of a roll stand similar to FIG. 1 showing the roll housing laterally displaced for removal or replacement;
  • FIG. 4 is a horizontal cross sectional view taken on line 44 of FIG. 1;
  • FIG. 5 is a horizontal cross sectional view taken on line 55 of FIG. 1;
  • FIG. 6 is a horizontal cross sectional view taken on line 66 of FIG. 2.
  • numeral 2 designates. the casing which encloses the gearing for driving the rolls.
  • Casing 2 is mounted on cantilever base 4 overlying the roll pass.
  • the enclosed bevel gears (not shown) are coupled as at 6 to shaft 8 which is in turn coupled as at 10 with shaft 12 of the main driving motor 14.
  • Spindles 16 and 18 are of the extensible telescoping type and are suitably coupled as at 20 and 22 to shafts 24 and 26 which are driven through the gearing arrangement enclosed in casing 2.
  • the lower portions of spindles 16 and 18 are comprised of coupling boxes 28 and 30 which are interiorly shaped to receive the mating wobblers 32 and 34.
  • the spindles 16 and 18 are enclosed within a shield 36 which is shown in place over the roll housing 38 in FIG. 1, and in its raised position in FIG. 3.
  • spindles 16 and 18 Prior to any lateral displacement of roll housing 38, spindles 16 and 18 are disconnected and raised sufficiently to clear wobblers 32 and 34, and shield 36 is raised through a distance suflicient to clear studs 40 which hold the shield 36 in place over housing 38 during the rolling operation.
  • Cylinder 42 is actuated and act through rod 44 to exert a clockwise force on bell crank 46 which is pivoted as at 48.
  • Bell crank 46 in turn exerts a pull on cable 50 which passes over wheel 52 and is attached to rod 54 as at 56.
  • Rod guide sleeves 58 and 60 are welded to shield 36. These support guide rod 54, allowing it to move vertically.
  • Collar 62 is fixed to rod 54.
  • Spindle carrier frame 64 rests on collar 62 and may be moved vertically within shield 36.
  • Rollers 66 and 68 are suitably attached to spindle carrier frame 64 and are positioned to come sequentially into contact with collars 70 .and 72 on spindles 16 and 18 as the spindle carrier frame 64 is raised.
  • rod 54 is raised and acts through rod collar 62 to raise spindle carrier frame 64. Since spindle collar 70 is lower than spindle collar 72, spindle 16 is raised by rollers 66 before spindle 18 is raised by rollers 68.
  • rod 54 continues to move upward;'spindle carrier frame 64 soon contacts rod guide sleeves 58 and exerts an upward force on shield 36, raising the shield through a distance sufficient to clear studs 40. As can be seen in FIG.
  • the staggered position of spindles 16 and 18 enables a man to reach through opening 74 in the rear of shield 36 and first position coupling 30 overwobbler 34.
  • Connection can be made lowering frame 64.
  • coupling 28 is positioned over Wobbler 32 and the frame 64 is lowered further to complete the connection.
  • rollers 66 and 68 in contact with collars 70 and 72 allow the spindles to be rotated about their longitudinal axes, thereby facilitating the task of aligning the irregularly shaped wobblers 32 and 34 with the mating driving surfaces of the coupling boxes 28 and 30.
  • Shield 36 is then secured to housing 38 by studs 40.
  • the rolls 76 and 78 are positioned in conventional manner within housing 38.
  • Pass guides 82 and 84 may be mounted on housing 38 by means of rest bars 86 and 88.
  • the housing 38 When in operating position, the housing 38 rests on parallel box girder beams 90 and 92, (see FIG. 4) which are in turn fixed to a rectangular frame comprised of beams 94 and 96 located parallel to the pass line and beams 98 and 100 located transversely to the pass line.
  • the rectangular frame and beams 90 and 92 will be collectively referred to as an elevating platform 102.
  • Housing 38 is secured to platform 102 by a plurality of .pivoted studs 104 or otherwise as may be convenient.
  • the pivoted studs 104 are re! ceived within recessed bifurcations 106 in housing 38 and locked in place by keys 108.
  • a trough 110 is integrally fabricated within platform 102.
  • the water and scale is caught by trough 110 and discharged into flume 112 located within the mill foundation.
  • the floor 114 of the fiume 112 is slanted to produce a flow in a direction aligned with the pass line.
  • Platform 102 is supported at each corner by vertically disposed screw shafts 116 located under the ends ofbeams 98 and 108. Screw shafts 116 are fixed to beams 98 and 100 and do not rotate. As shown in FIG. 5,, nuts 118, vertically immovable, are threaded upon shafts 116 and are provided peripherally with worm gear teeth 120. The worm gear teeth 120 are adapted to mesh with Worms 122 carried by horizontal shafts 124. The horizontal shafts 124 are in turn equipped with Worm gears 126 designed to mesh with worms 128 carried by shaft 130. It will be apparent from this description that when motor 132 is energized, shafts 124 will be simultaneously rotated, causing the vertically disposed screw shafts 116 to move up or down within nuts 118 to raise or lower platform 102 as desired.
  • the platform 102 is held in place by two Watt Linkages 134 located on either side of the pass line. See FIGS. 1, 2 and 6.
  • Each of the Watt Linkages is comprised of arms 136 and 138 pivotally secured to beam as at 140 and beam 98 at 142, and to member 144 as at 146 and 148. Member 144 is in turn pivotally secured to pedestal 150 as at 152.
  • Pedestal 150 forms a part of base 154 which is secured to the main mill foundation 156.
  • the two Watt Linkages, one on either side of the platform are particularly suited for this arrangement, since they effectively prevent anyhorizontal platform movement in the direction of the pass line, yet allow vertical adjustments to be made by the vertically disposed screw shafts 116.
  • Platform 102 is then lowered to the level of tracks 158 by energizing motor 132 and causing the vertically disposed screw shafts 116 to operate.
  • the tracks 158 are located laterally of the pass line and preferably slightly below the mill floor. For safety purposes, when not in use the tracks 158 may be covered by steel plates or grating.
  • platform 102 can be elevated or lowered to any desired level, an alternate arrangement is possible whereby housing 38 could be laterally displaced to a movable platform and rolled aside in preparation for the lowering of a spare housing by an overhead crane onto a second set of tracks in line with beams 90 and 92.
  • the housing 38 when fully displaced, the housing 38 is clear of the overhanging driving mechanisms and can be easily removed by an overhead crane or other suitable means, A spare housing containing new rolls and pass guides fully positioned and adjusted can then be lowered on tracks 158 and pulled back into position on platform 102 by piston 160.
  • the housing 38 is then secured to beams 90 and 92 comprising the upper surface of platform 102 by pivoted studs 104 and keys 108, and raised to a position where the spindles 16 and 18 and shield 36can be lowered and secured.
