Definitions

  • This invention relates to the metal working industry and is particularly concerned with the provision of new and novel means for eiiecting axial adjustment of the rolls in a rolling mill.
  • the present invention contemplates an adjusting mechanism which permits the rolls to be axially adjusted with respect to each other While at the same time permitting vertical adjustment of the rolls as well as slight turning of the chocks in a vertical plane when the rolls are ached slightly as the metal passes therebetween.
  • the ability of the chocks and bearings to shift with the roll necks causes a reduction in bearing wear and minimizes shutdowns.
  • FIG. 1 is a plan view of one roll of a roll stand showing the chocks positioned in the frame with the adjusting mechanism connecting one of the chocks with the frame;
  • FIG. 2 is an end view of the upper portion of a roll stand showing the general location of the adjusting means

  • FIG. 1 a horizontal sectional view through a conventional roll stand is shown to orient the invention with respect to conventional mechanism.
  • the frame of the stand is shown at 2.
  • a roll 4 carried by the chock and bearing assemblies 6 and 8.
  • Attached to the lefthand end of chock 6 is the adjusting mechanism generally referred to at 8 which will be more particularly described in connection with the other figures that are on a larger scale.
  • the right roll neck to of roll 4 is connected in conventional manner at 12 with drive shaft 14.
  • the adjusting mechanism 8 is disconnected from chock 6, drive spindle 14 is disconnected from roll neck 19, and the roll is withdrawn through frame 2 in conventional manner.
  • the general location of the adjusting mechanism with respect to the rolls may be further seen in FIG. 2.
  • the upper roll is indicated at 16 and the lower roll at 18.
  • the chock 6 has conventional flanges 20 under which are the chock supporting jaws 22 which are adjustable vertically in conventional manner by the bell cranks 24 acting in cooperation with the usual screwdowns 26.
  • the upper roll 16 may be set at a determined distance above lower roll 18.
  • the axial adjustment mechanism which is the subject matter of this application is applicable to both the upper and lower rolls 16 and 18. As the mechanism is the same for both rolls, description in relation to one roll will sufiice.
  • FIG. 3 The adjusting mechanism found in FIG. 2 is shown in larger scale in horizontal section in FIG. 3.
  • a U-shaped bracket 28 bolted to the end of frame 2 by four bolts 3i
  • a tubular bearing member 38 which has a circular flange 40 designed to limit its entry into sleeve 34.
  • a lock nut 42 having wings 44, is threaded onto member 38 to lock the latter in any desired axial position with respect to bracket 28.
  • An hexagonal interior opening 46 is provided at the end of member 38 whereby a cooperating tool may be inserted to rotate member 38 to move it axially the extent required in making the roll adjustment.
  • cover plate 48 On the end of chock 6 is a cover plate 48 held by bolts 50 (see FIGS. 4 and 5).
  • Cover plate 48 has two vertical flanges 52 and 54, oppositely grooved at 56 and 58.
  • the bottom of flanges 52 and 54 are joined by a crossbar 66 secured by bolts 62.
  • a second tubular bearing member 64 Residing between the two flanges 52 and 54 is a second tubular bearing member 64 having a discontinuous circular flange 66.
  • flange 66 is cut away at 68 and 76.
  • a stop 76 is applied to the side of the sleeve at a position where it will engage first one and then the other of the walls of grooves 56 and 58.
  • a set screw and lock nut assembly 72 is provided in crossbar 60 to secure member 64 against rotation and to support it at correct level when in the position shown in FIG. 4.
  • the adjusting mechanism is mounted.
  • Member 64 is further secured to the cover plate 48 through the use of lock nut 74 threaded on the member as shown in FIG. 3.
  • the lock nut when set up tightly, pulls the flanges 66 against theadjacent walls of the grooves, thereby makingrnember 64 substantially an integral part of cover plate 48.
  • the two bearing members 38 and 64 are connected by a dumbbell-like link 75 which comprises a shank '76 having spherical heads '78 and 30.
  • Circular bearing elements 32 and 33 form sockets in both members. These elements are held tightly against the spherical portions 78 and 30, under adequate pressure by the threaded discs 84 and 86 which are screwed into the sleeves with sufficient force to produce a tic-clearance situation.
  • the material of which the bearing elements 82. and 83 are made is of suchcharacter that the spherical heads '78 and 80 may swivel therein as up and down relative movement of members 33 and 64 may occur. That is to say, if the chock 6 is moved up or down or rotated slightly in a vertical plane, such motion may be readily accommodated by themovement of the dumbbell connection in the supporting members.
  • chock 6 where it engages frame 2 at surfaces 92 and 94 is free to move vertically with respect to the frame and to turn in a vertical plane.
  • the engagement is in the nature of a smooth sliding tit which prevents any movement of the chock in the direction of the'pass line while permittin movement up and down and axially of the roll.
  • FIGS. 6 and 7 A modified form of the invention is shown in FIGS. 6 and 7.
  • the same basic principles found in FIGS. 3, 4 and 5 are present here, the differences residing in the manner in which adjustment is accomplished and in the means whereby the axial adjusting means may be freed from the cover on the end of the chock.
  • the roll 16 has its roll neck 1% supported by chock 162 in the usual manner.
  • This includes a sleeve 194 fixed on the roll neck that is in bearing engagement with the interior or" the chock. Endwise movement of the chock with respect to the sleeve and roll is prevented by a thrust bearing 1%.
  • a cover plate 108 closes the end of the chock.
  • the chock 152. engages frame 110 through suitable engaging pads 112 and 114, which pads make smooth sliding engagement with each other to permit the chock to move up or down and axially while preventing movement of the chock in the direction or" the pass line.
  • Frame 119 includes U-shaped extension lid on which This includes adjusting screw 118 rotated by hand wheel 12%.
  • Lock nut 122 rotated by hand wheel E24, serves to lock adjusting screw 11% in any selected position.
  • On the right end of adjusting screw 118 is spherical element 12% which is suitably secured within a two-part cylindrical casing 123.
  • the casing includes circular bearing elements 13!? forming sockets which also support at the otherend of the casing a spherical element 132 similar to 126 that is mounted on the end of a threaded member 13%.
  • nut 138 Mounted on member 13% is nut 138 having afilxed to its inner face a Washer let which resides in opposed shallow recesses 14?. and 143.
  • nut 144 On the extremity of U164 ber 13 5 is nut 144 pinned thereto by pin 146. Nut 144 is located in vertical slot 148, as can be seen in FIG. 7.
  • hand wheel 12% may be rotated to shift adjusting screw 118 axially, and this will cause corresponding axial movement of check i132 and associated roll 16.
  • nut 138 is backed off suiliciently so that screw 134 may be raised or dropped enough to free it from slot 148. The roll may then be removed from the housing in the usual manner.
  • FIGS. 6 and 7 provides an adjustable connection between the frame and the roll chock which acts in the same manner as that described in FIGS. 3, 4 and 5 in that the chock 1&2, after axial adjustment, may move up and down in accord with any vertical adjustment made to the roll and is also free to turn in a vertical plane as the roll neck may be deflected when arching of the roll occurs during the rolling operation.
  • FIGS. 8, 9 and 10 A third form of the invention is shown in FIGS. 8, 9 and 10. This construction is not unlike that shown in FIGS. 3, 4 and 5, but axial adjustment of the roll chock and roll is achieved by somewhat difierent mechanism.
  • roll 16 has its roll neck 15% mounted in chock 152 which resides in frame 154 in the usual manner.
  • the frame and chock pads 156 and 158 engages each other to permit the chock to move in all directions except in the direction of the pass line.
  • the usual thrust bearings 16d connect the chock to roll neck 1% so that any axial movement imparted to the chock will result in corresponding movement of roll 16.
  • the chock has a cover plate 16% secured thereto by bolts 162.
  • Cover plate 16% has two oppositely disposed curved grooves 164 and 165 behind walls 174 and 175. In the grooves are positioned flanges T165 and 1&7 on the end of a sleeve M8. The flanges are cut away on opposite sides as at and 1'72 (see FIGS. 9 and 10). When sleeve 16% is in the position shown in FIG. 9, flanges 166 and 167 are behind walls 174 and N5. When sleeve 168 is rotated 90 degrees to the position shown in FIG. 10, the cut-away sides 17% and 3.72 are narrow enough to be withdrawn between walls 174 and 1*?5.
  • sleeve 16% When sleeve 16% is in the position shown in FIG. 9, it may be locked against rotation by lock nut 176 which has Wings 178 to facilitate its rotation.
  • Two circular bearings 189 and 32; forming a socket are positioned in the sleeve 168 to engage and hold a spherical member 134.
  • the bearings may be forced into tight position with member 18 by the flanged cap 186 which may be locked in position by lock nut 18%.
  • Spherical member 184 is mounted on a threaded shaft 1%, being held in axial position thereon by nuts 192 and 1%. On the other end of shaft 1% is a similar arrangementcornprising a like spherical element 196 secured in position on the shaft by nuts 1% and 2%.
  • Spherical member 196 is mounted in sleeve 202 in the socket formed by circular bearings 2M- and 2%. These bearings are secured in position in the sleeve by a flanged cap 2% which may be secured against loosening by lock nut 210.
  • Sleeve 2G2 is positioned in a circular opening in a U-shaped extension 212 of housing 154. Nut 214, acting in cooperation with circular flange 216, holds sleeve 292 firmly in position on the frame 212.
  • the spherical members 184 and 196 in their respective sockets are in a noclearance relationship so that any adjustment of shaft 190 with respect to spherical element 196 will produce a corresponding axial movement of chock 152 and roll 16.
  • the connection is of such character that the chock 152 may be moved up or down within limits without disturbing the axial adjustment and likewise as the roll 16 may be arched to deflect the roll neck 150 the chock may shift correspondingly as permitted by the rotation of spherical members 184 and 196 in their sockets.
  • Means for etfecting longitudinal adjustment of a roll in a roll stand and for holding the roll in fixed longitudinal position once the adjustment has been attained and without restricting the vertical movement of the roll within limits and without restraining movement of the chock as it is moved by the roll neck in accord With roll deflection or misalignment said means comprising a chock fixed axially with respect to the roll, a member fixed with respect to the roll stand and spaced in an axial direction from the chock, a no-clearance flexible connection between said chock and member, said connection comprising a first element rigidly connected to said member, a second element rigidly connected to said chock, and a third element pivotally connected to both said first and second elements whereby said chock is fixed axially but can move up or down within limits with respect to said member or turn in a vertical plane within limits without restraint by said second and third elements.
