7 Claims.

This invention relates to improvements in an edging roll means used in steel mills for rolling hot metal bars for reducing their width, and particularly pertains to the use of adjustable means or insert filler guide bars which are readily attached to and detached from some stationary part adjacent the edging rolls whereby the edging roll means is caused to accommodate the rolling of hot metal bars of different thickness without requiring a change of the edging rolls or a set thereof each time that a hot metal bar of different thickness is to be rolled. The adjustable means adapts the rolls to bars of different thicknesses or the insert filler guide bars are to be changed rather than the edging rolls for the adjustable edging roll is mounted in a journal support that can be actuated by a screw device Y or other suitable means for adjusting the edge roll journaled thereon relatively to the other edging roll which is preferably stationary. However, no ready adjustment means have heretofore been found for adapting a single set or pair of edging rolls to accommodate the hot metal bars of diiferent thickness that are to be rolled. The practice in the art has required different sets or pairs of edging rolls for all the diiferent thicknesses of the bars which are to be rolled. There would need to be a separate set or pair of rolls for each different thickness of bars to be rolled. This, of course, is not only expensive in that a large supply of different pairs or sets of rolls are required, but much time is required in changing The time required for changing the rolls varies from thirty minutes to several hours, depending somewhat on the type of edging roll unit. Because change flange on each side of the recess.

of rolls has been accepted as the only solution of the problem, the more modern edging units have been constructed to make the rolls as easily changeable as possible. Production, of course,

necessarily stops while the roll sets are being posed about its peripheral face, leaving an end The width of the annular recess is such to the thickness of the bar of metal to be rolled that its marginal edge snugly fits into the recess of one roll and the opposite marginal edge of the bar snugly fits into the recess of the other roll.

It is the aim of this invention to employ edging rolls, having a recess of a width exceeding the maximum thickness of any metal bar that is to be rolled, and employ with said rolls either an adjusting means or a readily attachable and detachable accessory device or devices to reduce the width of the space to the width of the bar to be rolled. The adjusting means is generally typified by a collar or sleeve having an annular flange forming one side wall of an annular groove and adapted to be actuated to and from another side wall of the groove for providing a groove of the'desired width. The accessory device is generally typified by two sets (right and left hand sets) of guide or insert metal bars, one set of which is associated with one edging roll and the other set is associated with the other edging roll. Each set of guide or insert bars preferably comprise separate upper and lower bars. While the lower guide or insert bar is, like the upper guide or insert bar, readily attachable and detachable in position in respect to the roll, it can be used in rolling all the metal bars of difierent width and thus might be a permanent attachment if desired. Its bearing surface exposed to the metal bar being rolled is in alignment with the path of idle rolls or other devices over which the metal bar is fed to and from the edging device.

The cost of the guide or insert bars is not only inconsequential as compared with the edging rolls, but they can be changed in practically no time at all besides being more adapted for convenient handling and keeping in stock. The time and labor required for changing the guide or insert bars is merely that involved in removing one guide bar and substituting another guide bar therefor. With the guide or insert device as an accessory to the edging rolls, one set only of edging rolls is adapted for rolling metal bars of all the different thicknesses desired. With a single set of rolls and substitute guide or insert bars of different sizes, rolling of varying thicknesses of hot metal bars may be done by merely changing the different size guide or insert bars.

Referring specifically to the drawings in which like numerals are used to designate like parts, numeral 1 designates a frame or base on which

pedestals

2 and 3 are mounted. Pedestal 2 is usually stationary, whereas pedestal 3 is movably mounted so as to be adjusted to and from the stationary pedestal. The upper part of the pedestal 3 is provided with a journal bearing 4 capped by 4' bolted to the pedestal 3 at 5 to receive a shaft 6 to which is keyed at I a sleeve 8 and a beveled gear 9'. The sleeve 8 with upstanding end fianges rotates with the shaft in the bearing 4. The beveled gear 9' is mounted on the shaft in a position to mesh with a complementary bevel gear l which is mounted on and keyed to vertical shaft II. The Vertical shaft H is journaled in a bearing I2 in bracket I3 attached to pedestal 3. On the vertical shaft l l is mounted a roll l4 provided on its peripheral face with an annular recess l disposed between spaced apart fiange portions l6, resulting from the formation of the recess. These flanges l6 may be integrally formed with the roll [4' or be separate parts screw-threaded or otherwise attached to the rolls. The lower end of roll [4' is recessed at I! to receive the end 18 of a stub shaft, the other end 19, preferably reduced in diameter, of which projects and is fixed in bracket 20 provided on pedestal 3. An anti-friction sleeve 2| is inserted to line the wall of the recess I1 and anti-friction discs 22 are placed in a subrecess 23 formed in the roll l4 adjacent that end of the stub shaft which. fits in the recess I? of the roll.

The other vertical edging roll [4 is similarly mounted on the pedestal 2 and driven by intermeshing bevel gears 9 and H], the only essential difference being that pedestal 3 is adapted to be moved by some adjusting device, such as a screw 24 or the like. Leading to and from the edging device are any number of idle rollers 25, or the like, over which a heated bar of metal A is to be conveyed to the edging device for being reduced in width. Thereafter the bar may be fed to other edging rolls of like construction to be further reduced in width after in the meantime having been fed through horizontal rolls for reducing its thickness. In drawing out and rolling the metal bar, it is alternately fed to a set of horizontal and edging rolls.

With an edging device, typified by the above described construction, there is provided a set of left and right upper guide or insert bars 26 and a set of lower guide or insert bars 21 which can be advantageously associated with a single set of vertical rolls to accommodate bars of different thicknesses for rolling.

Upper guide bar 26 is of indefinite length suitable for providing a substantial bearing surface 28 on its underside to contact with the upper marginal side of the bar being rolled. One guide or insert bar 26 is supported in position in respect to the roll by means of a bracket 29 attached to the pedestal 2 on one side of roll l4 and a bracket 30 on the other side of roll [4. Bracket 29 has a base portion bolted at 3| to the pedestal 2 or some other stationary part, and a part 32 projecting to receive the ends of guide bars 26 and 21 to which they are attached by

bolts

33 and 34 extending through recesses formed in the bracket and the ends of the guide bars 26 and 21. The other guide or insert bar 26 is likewise attached by

brackets

29 and 30 in similar disposition to the other vertical roll. l4.

The other ends of the guide bars are supported by the bracket 30 which has a base part 35, reenforced by rib 36, bolted to the pedestal 2 by bolts 31. The bracket projects to form forked

arms

38 and 39. Upper arm 38 is recessed at 4!! and 4| to receive the

respective fins

42 and 43 on the upper guide bars 26. The upper guide bar 26 is slid into place with the

fins

42 and 43 on the guide bar interfitting with corresponding grooves 40 and 4| on the brackets. Abutment 44 may be advantageously provided on the upper guide bar 26 to limit insertion of the bar when the recess in its opposite end bar is in alignment with the recess in the bracket for insertion of bolt 33 which holds the upper guide bar in its assembled position with respect to the edging roll and attached to the brackets. The bolt 33 is not necessary but is merely representative of any positive means for securing the guide bar in its assembled position.

The lower arm is provided with

similar grooves

45 and 46 to receive respective fins 4'1 and 48 on the lower guide bars 21. The fins prevent lateral displacement and the bolts hold the guide bar in position. Bolt 34 is not necessary but is representative of any positive means for securing the guide bar in its assembled position.

It is apparent from the above described construction that the upper guide bars or both are each readily inserted and removed, thereby permitting the same rolls to be used for rolling metal bars of different thickness. Upper guide bars of different thickness through the cross-sections that fit within the recess of the edging roll are employed and inserted to accommodate rolling bars of different thickness.

The annular flanges l6 forming the side walls of annular recess l5 in the periphery of the vertical roll are either integral with or separate members attached to the roll. If in the form of separate members, they can be advantageously screw-threadedly connected with the rolls so as to be adjusted to the proper width for providing a recess therebetween of the desired width. The modified construction in Fig. '7 typifies an edging roll unit comprising a pair of vertical rolls, each being provided with a collar 49 screW-threadedly attached to the roll i4 at 56 to secure an antifriction bearing between the collar 49 and a shoulder on the roll. The anti-friction bearing comprises spaced apart rings 52 and 53 providing a raceway for the balls 54 which are interposed therebetween. The seat of shoulder 5| is in alignment with the top surface of guide bar 26 which is adjacent the roll, thereby permitting ring 53 to seat on the shoulder and the top surface of the guide bar. To prevent the ring from rotating with the roll, a downwardly extending lip 55 may be provided to abut the front edge of the guide bar 26. A duplicate construction is provided on the bottom end of the roll [4 for cooperation with the lower guide bar 27.

The modified construction in Fig. 8 typifies an edging roll unit having the vertical rolls each provided with an adjustable collar or flange in relation to a stationary collar or flange on the roll. The vertical roll has a reduced neck screwthreaded at 56 to receive nut 51 and a further reduced neck screw threaded at 58 to receive a lock member 59 fastened to the roll by set screw 60. Nut 51 is an inverted-cup-shaped member with the bottom rim flange 6| forming a side wall of an annular groove opposite to flange I6, integral with the roll, which forms the other side wall. Lock member 59 is of similar shape with its bottom rim embracing the upper part of nut 51 and carrying set screws 62 to engage in respective vertical grooves or recesses 63 in the outer wall of nut 51'. As the nut member 59 is screwed down or up on the threaded neck of the roll, the wall of the groove or recess is moved to or from the stationary flange or wall, thereby varying the width of the recess to the thickness of the metal bar A that is to be rolled.

The modification in Figs. 9, and 11 consists in providing front upper and lower guide bar sections 64 and 65, respectively, and rear upper and lower guide bar sections 66 and 67, respectively, a set of these being provided for each vertical roll. Rear bracket 68 is similar to that in Fig. 5, but the front bracket 69 is elongated so that it acts as a splice for the bar sections of each pair. Holes 10 and H are provided to receive bolts 12 and 73 which respectively engage the recesses 14 and in the bar sections. This front bracket 69 has ribs 76 and 11, respectively engaging in

recesses

18 and 19 formed in the side faces of the adjacent ends of the bar sections, thereby preventing the bars from springing out of place. The

bolts

12 and 13 are merely used as additional precautions for holding the bar sections in assembled position in the brackets. They could be omitted if desired. Each set of bar sections are flared at both front and rear, thereby permitting the metal bars that are to be rolled being fed to the rolls in either direction.
