Definitions
- This invention relates to rolling mills and has for an object to produce a mill which overcomes diificulties heretofore encountered with such machines.
- a more specific object is to produce a mill which is particularly adapted for rod and bar mill work and which overcomes difficulties encountered in connection with such work.
- Rod. and bar mill products are likely to be faulty, due to a lat-- occasioned by what is termed roll sprin
- roll spring results from two causes, viz., deflection of the reducing rolls when subjected to the rolling pressures, and a bodily moving apart of those rolls in response the work- 0 ing strains to which they are sub ected.
- Roll spring as above defin is recognized in the design and. operation of rolling mills, but 1t 7 is difiicult to control and consequently it is diflicult with the ordinary form of rod or bar mill, to roll products to the desired thickness.
- a specific object-of my invention is to pro-' cute an improved mill which will unprove rod and bar mill products.
- Fig. 2 is an end elevation of the mill shown in Fig. 1.
- Fig. 3 is a more or less diagrammatic view of the adjusting mechanism for the reducing rolls; and i Fig. 4 is a fragmentary sectional view of a slightly modified embodiment of my invention, in which the scale of the drawings is increased for convenience of illustration.
- the illustrated embodiment of my invention includes a pair of workin rolls 55," which are illustrated as provide with grooves or matrices 6, forming the effective passer throat of the rolls.
- These rolls are essentially convex' or barrelshaped in that they are provided with convex peripheral surfaces on each side of the grooves or matrices. That is, each roll tapers .on a curved, convex surface from the effective pass or throat toward each end so that it is of greatest diameter at the center and tapers to a smaller diameter at the ends.
- Each reducing roll is preferably bi-laterally symmetrical about the center line of its groove or matrix.
- the rolls 5-5 overhang their sup rting bearings, and are so mounted that t ey are free to move laterally or axially an appreciable amount, but are located between backing rolls 7 and 7a, which are shownas concave rolls in that the periph- I eral surface of each roll is of greater diameter at the ends than at a point midway between the ends of the roll, and tapers along acurved concave surface toward the intermediate portion of the roll.
- the concave surfaces of each backing roll are so formed that they correspond m curvature to the convex surfaces of the reducin rolls and artially embrace a reducing r0 1 along the line of contact therewith, thus preventing relative axial movement between each backing roll and the reducing roll engaged by it.
- the bac ing rolls are preferably of relatively large diameterascomparedto the reducv ing rolls, and are so constructed, both as to the body of the rolls and the roll necks, as to prevent appreciable deflection or yield under the stresses encountered during the rolling operation.
- each backing roll is so mounted that lateral or axial displacement is substantially prevented.
- this is accomplished by providing two forms of bearings for each of the rolls, at least one of which operates in part as a thrust bearing in that it resists lateral or axial movement of the roll.
- the overhanging reducing rolls are reinforced by the rugged backing rolls so that the bearings of the reducing rolls are relieved of substantially all the working pressure to which the reducing rolls are subjected during the operation of the mill.
- An important feature of this invention is the fact that the backing rolls are held meshing engagement between the opposed and contacting surface of each reducing roll and its cooperating backing roll holds the reducing roll against lateral displacement during the operation of the mill.
- the mill includes a frame 9, which essentially consists of a pair of standards 10 at the front of the machine, an intermediate pair of standards 11 and a rear extension 12 which terminates in a rear window 13.
- the various parts of the frame are cast or otherwise assembled into a rigid structure.
- the standards 10 are located on either side of forward window similar in function to the windows employed in the ordinary rolling mill.
- the standards 11 are located on either side of an intermediate window which also corresponds in function to the windows of theordinary mill. With this arrangement the mill is provided with three windows, the forward, the intermediate and the rear window.
- each working roll 5 is mounted on the overhanging end. of a spindle 14:, which in turn is journaled in a specially formed bearing block 15.
- Each bearing block 15 is provided with spaced bearings 16 for the associated spindle and is so formed that it is per bearing box 15 is held in place by adjust-' able members 17 and 18.
- the lower bearing box" is adjustably supported by similar members 17a and 18a. With this arrangement the adjustable members are capable of holding the bearing boxes 15,and consequently the reducing rolls 5 in the desired vertical position.
- each of the members 17 and 17a is secured to its associated bearing block 15 by a socket connection and extends through a suitable guiding aperture formed in the frame. It is provided at its outer end with an operating wheel 20, having a screw thread engagement therewith and so mounted in thrust bearings that a turning of the wheel will shift the member in one direction or the other, thus adjusting the position of the forward end of the associated bearing box 15. It is apparent that ball and socket joints may be employed between the members 17 and the boxes 15 or any other form of connection which wi ll permit slight angular motion between the member and the box but will hold the box in the adjusted position.
- Each member 18 and 18a is likewise provided with an operating wheel 21, but the wheel is mounted on the outer end of the member by means of a feather-key, so that it rotates with the member but is capable of moving or sliding along'the member.
- the member is threaded through a suitable aperture in the frame, so that its rotation changes its longitudinal position. With this arrangement, turning the wheel, shifts the longitudinal position of the member and thus positioning the outer end of the associated box 15 within its guides.
- Fig. 3 I have diagrammatically shown operating connections for the wheels 20 and 21.
- the wheels are diagrammatically shown as worm gears and in the upper view, the two wheels 20 and 21 are shown in connection with an arrange ment, wherein they may be operated separately.
- the shaft 24; carries a worm 25, which meshes with the gear 20.
- ears 20 and '21 may be operated together or independently.
- Fig. 3 In the lower view of Fig. 3,
- the spindles 14 are shown tapered at their forward ends. This is for the purpose of simplifying the operation of mounting the reducin rolls 5 in place on the spindles and it is, 0 course, understood that these rolls are provided with correspondingly tapered employed for obtaining a rigid driving connection between the rolls and the spindles. It is desirable that each spindle be a driven spindle and for this reason both spindles are shown provided with coupling. boxes 27, but the coupling boxes are so arranged that each spindle is capable of shifting axially in its bearings.
- each backing roll is, of course, of rugged or strong construction. It is desirable to make them as short as practical between their necks or bearings and it is also desirable to provide them with large and relatively stifi' necks, the reasons for which are all clearly understood in rolling mill design.
- FIG ;1 of the drawings I have shown each backing roll as provided with one straight bearing 28 and one double conical bearing 29.
- the double conical bearing is employed to resist lateral displacement of the backing roll during operation.
- Bearing boxes are provided for the backing roll and these boxes may be mounted in the forward and intermediate windows of the frame in the usual manner of mounting the rolls in a mill. It is, of course, understood that the bearing boxes are so formed that the rolls are aligned by the standards 10 and 11, which form a way in which the lower bearing housings may be guided, during the operation of adjusting the positionvof the lower backing roll.
- the bearing box structure 30 is vertically adjustable along the ways formed by the standards 10 and 11 so as to efiectively'bring the backing rolls into operative relation with the reducing rolls.
- Any suitable structure may be employed for this purpose andin the drawings I have diagrammatlcally shown adjustable struts 32 for moving the bearing housing'30 to position and for supporting the housingv in position. As there shown, each strut is shown threaded through a suitable aperture in the mill frame and is rovided with an operating wheel 33, which 1s feather-keyed onto the strut near its lower' end.
- Each wheel is diagrammatically illustrated as a worm wheel, and is adapted to mesh with a separate worm mounted on a shaft 35.
- the shaft 35 is preferably operat-- ed from the front of the mill by a sultable hand wheel not shown.- With this arrangement the position of the bearing box 30 may be varied by turning the shaft 35, thereby varying the position of both struts, but it will be apparent that each strut may be independently adjusted.
- the bearing box 30 is provided with flanges 30a along each side, which overlap the standards 10, and determine the posibe tion of the box 30 within the forward and intermediate windows.
- Clamps 30b act between the frame and the flanges to rigidly hold the box in the proper endwise or lateral position.
- the clamps are held in place by bolts which extend through slots formed in the clamps.
- the bearing box 31 for the upper backing roll is not vertically adjustable. It is adapted to be clamped and held in position againstthe upper arch 34 or cap of the mill. Its lateral position" is also important and for this reason I .have illustrated a mechanism 35 for adjusting the lateral position of the bearing box and for holding it rigidly in place.
- the mechanism 35 consists of a plate 36 which is rigidly secured to the frame bymeans of bolts 3601 A sleeve nut 37 is threaded through this plate, and a tension bolt 38 extends through this sleeve.
- the bolt 38 is provided with a head 39 which engages a recess formed in the box 31-.
- the sleeve nut '37 abuts against the box -31 and .is provided n't.
- Fig. 21 have also disclosed gui e clips 10a which,'if desired, maybeemployed as an additional means for rigidly holding the box in place.
- the box- 31 is preferably made in two parts, for convenience. of removingv the roll 7 therefrom.
- the lower portion 31b of the box is preferably secured to the upper portion by means of bolts, not shown.
- the reducing rolls may be readily changed for the purpose of rolling different forms of products but it will, of course, be understood that the peripheral faces of each reducing roll will correspond in contour so as to effectively cooperate with the backing rolls and thereby prevent accidental and undesired lateral displacement. It will also be understood that the usual practice will be adhered to in forming the working grooves or matrices in the rolls and that the rolls may be spaced apart to provide a definite predetermined roll set.
- the reducing rolls and their backing rolls with proper cooperating surfaces the reducing rolls may be effectively held in the desired position throughout the operation of the milland at the same time may be of relatively small diameter and mounted on sp1ndies of relatively small diameter, since the hacking rolls function to not only transmit substantially all the rolling pressure to the frame, but also to so hold the reducing rolls that appreciable lateral play or displacement of these rolls is prevented throughout the operation of the mill.
- each spindle will be provided with two such bearings located and arranged as illustrated in Fig. 1, and that the spindles must be capableof moving laterally with relation to their bearings.
- each roll 7' of Fig. 4 is somewhat different in contour from those shown in Fig. 1, the same principle is followed.
- Theintermediate portion of each roll is of reduced diameter so that there is no contact between the portion of each reducing roll and its cooperating backing roll immediately adjacent to the edges of the groove or matrix in the reducing roll.
- the lateral peripheral surfaces of the backing rolls are concave, increasing in diameter from the intermediate portion toward the ends of the rolls and along a curved line which corresponds to the lateral curvature of the convex peripheral faces of the reducing rolls.
- the rolls are similar to those disclosed in Fig. 1 and byemploying such concave and convex surfaces as are illustrated.
- the axes of the reducing rolls may be out of parallel with the axes of the backing rolls, without damaging the surfaces of the rolls and without materially increasing the rolling friction between each reducing roll and its cooperating backing roll.
- each spindle 14 is provided with two roller bearings 16 and each backing roll is provided with roller bearings 28' and 29'.
- the bearmgs 28 are especially constructed so as to conform in function to the double conical bearings illustrated in Fig. 1. This is accomplished by providing each bearing 28 with two sets of rollers in which the axes of the rollers of each set are inclined to those of the rollers of the other set, and so that the two sets of rollers cooperate with a double conical surface formed as a part of the roll neck, thus acting as a double thrust bearing and preventing appreciable lateral displacement of the backing roll.
- the bearings 29 are shown as straight roller bearings. It will, of course, be apparent that any form of anti-friction hearing may be employed so long as provision is made to prevent lateral displacement of the backing rolls.
- concave and convex surfaces of the backing rolls and reducing rolls may be tapered along curves other than those shown and described, It is preferable, however, to employ concave convex surfaces which are tapered along cave convex surfaces as illustrated and de-' scribed in connection with Fig. 4.
- a pair of-coacting reducing rolls having peripheral faces which diverge along a curved line from a point adj acentthe throat of the rolls toward the ends thereof, and apair of cooperating backing rolls having peripheral surfaces so formed as toicontact with the peripheral surfaces of said reducing rolls along a curved line, whereby relative lateral motion is prevented between each reducing roll and its c'ooperating backing roll,and means. for limit- -ing lateral motion of the backing rolls during their'rotation.

- bearing boxes for said backing rolls mounted in the forward and intermediate windows of said frame, and at least one thrust bearing for each backing roll for opposing lateral or endwise movement thereof during its rotation.
- a pair of roll spindles means for separately adjust ing the position of each spindle, a reducing roll mounted on the overhanging end of each spindle, a pair of backing rolls cooperating with said reducing rolls, the contacting surfaces of each reducing roll and its cooperating baekin roll extending at an angle to the axes 0 both rolls, means for adjusting the lateral position of one of said backing rolls, and a thrust bearing for each backing roll.
