Definitions

  • PATENTED W21 SHEU 5 [IF 5 ROLLING STAND FOR ROLLING SUBSTANTIALLY ROD-LIKE STOCK
  • This invention relates to a rolling stand for rolling substantially rod-like stock, such as wire, and particularly to a rolling stand for rolling substantially rod-like stock having at least three interchangeable driven working rollers which are disposed radially about the longitudinal axis of the stock being rolled.
  • the pass is formed either by two or by three rollers.
  • the threeroller pass has several basic advantages over the tworoller pass, such as for example better elongation of the stock being rolled in the pass with less spread, thereby improving rolling efficiency. Also with a three-roller pass deformation is more uniform so that there is better stress distribution in the stock. Three-roller passes are therefore able to roll even materials having poor deformation properties. such as for example sintered tungsten and molybdenum, without difficulty. These mate rials, which are only deformable with difficulty, may also be processed using the same sizing gap.
  • the temperature rise of the stock during the rolling process with three-roller passes is less than with two-roller passes so that it is possible to obtain high mean tensile strengths of the rolled stock, higher rolling speeds and thus greater production outputs, and greater economy.
  • the use of three-roller passes also prevents unintentional adverse changes in the properties of the materials, for example as a result of overhigh temperatures during rolling, which is particularly important when rolling high-quality steel.
  • With three-roller stands it is possible to roll without twist, thereby protecting the surface of the stock.
  • the forces arising during rolling are distributed among at least six bearings, whereas there are only four bearings in tworoller stands.
  • a three-roller stand can withstand and exert higher rolling pressures.
  • the present invention provides an adjustable stand which has at least three rollers and which apart from having the abovementioned advantages, meet, additional requirements. It is possible to keep within the narrowest tolerances over a longer rolling stand time since the rollers can be adjusted during rolling of a specific dimension several times by the smallest amounts, which are in the order of magnitude of the tolerance. It is also possible to reduce rolling and requipment costs as the rollers may be refinished several times in the same stand.
  • the aim of the invention is to provide an adjustable rolling stand having three interchangeable driven working rollers disposed radially round the longitudinal axis of the rolling stock and which overcomes the problems of the prior art discussed above.
  • all the working rollers together with their spindles are jointly and centrally adjustable radially relative to the longitudinal axis of the stock being rolled by means of a single adjusting spindle. if required, the working rollers may also be individually adjustable.
  • the adjustability according to the invention of the three working rollers of the stand has the added advantage that, as regards dimensions, it is possible to keep within even narrower tolerance limits than before and to improve the accuracy of shape of the rolled stock.
  • the adjustability, in particular of the last rolling stands of a rolling-mill line makes it possible to regulate the quantity of material running into the last passes so that filling of the passes can be regulated within specifie limits while retaining optimum tension conditions.
  • By adjusting the rollers, in particular in the last pass of a preliminary or intermediate line it is also possible to alter the first pass cross-sections for the subsequent lines.
  • the siight opening of the pass which is conditioned by the natural play in the roller bearings and is caused by the stock running through, can moreover be compensated by suitably adjusting the working rollers after they have been ground to size.
  • the construction according to the invention also substantially reduces rolling costs since the rollers of a rolling stand can be reground ten to fifteen times in their installed state and can be used again after grinding at the same point of the rolling-mill line. Only after the working rollers of a stand have been reground ten to fifteen times is it necessary to change the location of the stand relative to the stock being rolled. a process which. in a non-adjustable stand. is required after the very first re-grind. The expensive process of changing the rollers is therefore undertaken much less frequently so that the cost of this process maybe reduced by as much as 60%. There is significantly better use made of even the expensive working rollers.
  • the rolling stands according to the invention can obtain rolled stock dimensions which differ slightly from the gauges for which the rolling pass is actually designed. These intermediate dimensions can be obtained by suitably adjusting the working rollers without having to alter the rolling pass though this affects the accuracy of shape.
  • almost every cross-sectional dimension in the dimension range of the rolling stand can be rolled continuously.
  • the drive of the rolling stand according to the invention is constructed so that the driving speeds may be regulated over an adequately wide range. If the dimension of the rolled stock is to be retained and only the natural wear of the rollers is to be compensated. it is usually sufficient simply to regrind and adjust the last stand. Thus, in many cases only one or two adjustable stands are required per rolling-mill line.
  • the spindles of the latter are supported in radial bearings.
  • radial roller bearings which are in turn located in bearing bores in adjusting bushes and the bearing bores are placed eccentrically relative to the outer peripheral surfaces of the adjusting bushes and the adjusting bushes are rotatably journalled by their peripheral surfaces in housing bores in the rolling stand.
  • an adjusting range is obtained which is dimensioned according to the degree of eccentricity of the bearing bores and is in the region of, for example, 2 to mm. this being dependent in particular upon the diameter of the rollers. This adjusting range is quite sufficient to achieve the abovementioned advantages.
  • the adjusting movement is effected by a corresponding rotational movement of the adjusting bushes.
  • At least one adjusting bush of each roller spindle is advantageously provided with a bevel gear by means of which the bush meshes with a corresponding bevel gear of an adjusting bush of an adjacent roller spindle with this embodiment of the invention it is sufficient to rotate one of the adjusting bushes to displace all the adjusting bushes of all the roller spindles in a similar manner.
  • a precondition of this is. of course. a transmission ratio of l:l between the bevel gears of the adjacent adjusting bushes. This in turn ensures that all the working rollers are at a constant distance from the longitudinal axis of the stock being rolled.
  • compensating means may. according to a preferred feature of the invention. be provided for effecting relative movements between the roller spindles and the respective associated drive bevel gears. These means maintaining their predetermined position relative to one another when the rollers are adjusted. Only by maintain ing the drive bevel gears in their predetermined position relative to one another can they function efficiently and enable all the working rollers of the stand to be driven in synchronism. By means of the compensating means the roller spindles can nevertheless be adjusted independently of the drive bevel gears.
  • the drive bevel gears as well as the roller spindles are advantageously radially.
  • journalled in the eccentric hearing bores of the adjusting bushes preferably the drive bevel gears are axially displaceable with the adjusting bushes relative to the roller axes.
  • At least one adjusting bush of each roller spindle is advantageously provided in the region of its peripheral surface with a longitudinal portion having an external screw thread which is in engagement with at least one fixed internal screw thread or internal thread portion. Rotation of the ad justing bush then also effects a suitably dimensioned axiai feed by means of which the associated drive bevel gear is moved along the common cone generatrix.
  • the drive bevel gears remain. independently of the radial adjusting movement of the roller spindles permanently on the same point of the stand and thus remain permanently and easily intermeshed.
  • the working rollers together with their spindles are individually adjustable also in an axial direction.
  • This embodiment makes it possible to re-install used but not worn rollers and use them again without refinishing because the slight axial displacements arising during reinstallation may be compensated by axially adjusting the roller spindles. This not only economizes on the expense of refinishing but also avoids additional grinding down of the rollers so that. in this case too. rolling costs are considerably reduced especially if the rolling program is frequently changed.
  • This last embodiment is consequently particularly suitable for rolling smaller quantities of stock, such as for example occur when rolling high-quality steel, whereas an embodiment of the invention not having axial adjustment is particularly suitable for rolling bulk produced steel when as a rule such a large quantity is rolled that the passes are used extensively, are worn out after rolling and so require regrinding anyway.
  • the rolling stand according to the invention is primarily intended for steel wire and rods and its advantages are evident in this particular field, it is basically quite possible to use such a rolling stand for roll ing tubular stock.
  • the rolling stand can process cold and hot stock.
  • FIG. 1 is a cross-section of a rolling stand having individually driven roller spindles
  • FIG. 2 is a section along the line IIII of FIG. 1;
  • FIG. 3 is a cross-section of a rolling stand having jointly driven roller spindles and axially and radially displaceable drive bevel gears;
  • FIG. 4 is a section along the line IV-IV of FIG. 3;
  • FIG. 5 is a section along the line VV of FIG. 3;
  • FIG. 6 is a diagrammatic illustration of the movement of two drive bevel gears
  • FIG. 7 is a cross-section of a rolling stand having jointly driven roller spindles but fixed drive bevel gears
  • FIG. 8 is a section along the line VIIIVIII of FIG. 7;
  • FIG. 9 is a section along the line IX-IX of FIG. 7.
  • the column 1 of a rolling stand supports three working rollers 2 disposed radially round the longitudinal axis 3 of the stock to be rolled.
  • Each working roller 2 comprises a rolling annulus 211 made of a wear-resistant material and two clamping discs 2b which hold the rolling annulus 2a and form the hub of the working roller 2.
  • Each of the working rollers 2 is journalled by a roller spindle 4 which is likewise made up of two parts, a main part 4a and a clamping part 4b. The two parts of each roller spindle 4 are drawn towards one another by means of a drawn bolt 5.
  • the working rollers 2 are journalled by their spindles 4 in the roller bearings 6 which are radial bearings and which are supported in the rolling stand I.
  • the outer races of the roller bearings 6 are located not directly in housing bores in the rolling stand I but in bearing bores in adjusting bushes 7.
  • the exception to this is a radial roller bearing 6a in an outerlying adjusting bush 70 because an axial bearing 8 is adjacent to this radial hearing 6a and both bearings are inserted in an adjusting bush 9 which is screwed into the adjusting bush 7a.
  • the adjusting bushes 7 and 7a are journalled in rotatable but axially fixed manner in the rolling stand I.
  • the bearing bores of the adjusting bushes 7 and 7a. which serve to accommodate the radial bearings 6 or the adjusting bush 9, are placed eccentrically relative to the peripheral surfaces of the adjusting bushes 7 and 7a which serve as bearing surfaces. Rotation of the adjusting bushes 7 and 70 therefore enables radial adjustment of the roller spindles 4 and the working rollers 2.
  • the two adjusting bushes 7 of each roller spindle 4, disposed at opposite sides of the other 2 are connected to one another by means of yokes Ill.
  • the adjusting bushes 7a are also connected non-rotatably by means of their bush-like extension 7b to the adjacent adjusting bush 7.
  • At least one adjusting bush 7 or 70 of each roller spindle 4 has a bevel gear 11 by means of which the adjusting bushes 7 or 70 of the various roller spindles 4 are coupled to one another.
  • FIG. 2 shows that rotation of the adjusting rod l2 causes its screw-threaded spindle 12a to be screwed in or out of a threaded bush [3.
  • the adjusting rod 12 is journalled in an axially fixed manner so that the threaded bush I3 is moved substantially in an axial direction with respect to the adjusting rod l2.
  • the threaded bush 13 is connected by a hinge pin 14 to an adjusting ring I5 which in turn encloses the bushlike shoulder 7b of the adjusting bush 7a and is connected by means ofa key 16 in a non-rotatable manner to the adjusting bush 7a.
  • the working rollers 2 are driven by .way of coupling I7, only half of which are shown, separately but synchronously by a gear (not shown).
  • the working rollers 2, in particular the rolling annuli 2a, are interchanged after loosening the nut 5b by rotating the draw bolts 5 so that their threaded ends are screwed out of the clamping part 4b.
  • the clamping part 4 can be axially displaced away from the main part 4a of the roller spindle 4 by means of the draw bolt 5.
  • the main part 4a of the roller spindle 4 is also axially displaceable on the opposite side so that, after the draw bolt 5 has been screwed out completely, the rolling annulus 2a can then be withdrawn from the now sufficiently large gap between the two clamping discs 2b. After installation of a new rolling annulus 20, assembly is effected by reversing the process.
  • radial adjustment of the working rollers 2 is basically the same as in the embodiment of FIG. I.
  • the radial bearings 6 are eccentrically journalled in adjusting bushes 7.
  • the adjusting bushes 7 of each roller spindle 4 are again connected to one another by yokes 10 or a bushlike extension 711 and are coupled to one another by means of bevel gears 11.
  • the adjusting movement is effected manually by means of an adjusting rod 12 and an adjusting spindle 18, 180.
  • a worn gear 19 rotates an adjusting shaft 20 whose rotational movement is transmitted to the adjusting bushes 7 by way of an adjusting ring 150 and a connecting rod 21, which is pivoted to the adjusting ring a and to the bushlike extension 7b of an adjusting bush 7.
  • the adjusting shaft has a second adjusting ring 150 and a further connecting rod 21 so that the two lefthand adjusting bushes 7 can also be pivoted.
  • FIG. 3 differs basically from the rolling stand of FIG. 1 in that in this case only a single common drive shaft 22 serving simultaneously as one of the roller spindles 4 is provided.
  • the driving torque which is transmitted by a gear (not shown) by way of a coupling (also not shown) to the lefthand end portion of the common drive shaft 22, is passed on by drive bevel gears 23 to the other two roller spindles 4.
  • the roller spindles 4 are tapered in the region of their working rollers 2 and the hubs of the working rollers 2 have a tapered bore so that the rollers 2 are non-rotatably and in an axially fixed manner fitted onto the roller spindles 4.
  • Oil or some other suitable pressure fluid can be urged, by way ofa system of bores (not shown) preferably in the hubs of the working rollers 2, under high pressure between the tapered surfaces of the working rollers 2 and the roller spindles 4 so that the latter, if required, may be separated from one another.
  • This is necessary for changing the working rollers 2 when the roller spindles 4 must also be axially withdrawn after the working rollers 2 have been detached in the previously described manner.
  • the roller spindles 4 are withdrawn by suitably rotating the draw bolts 5 whose threaded ends 5a are thereby withdrawn from the axial bearing 8. Once a roller spindle 4 has been disengaged in this way, it can be removed sufficiently for the working roller 2 to be interchanged. Otherwise, the bearings remain unaffected.
  • the drive bevel gears 23 are journalled in the radial bearings 6 and therefore effect the same radial adjusting movement as the working roller 2 and its roller spindle 4. So that this does not lead to damage of the drive bevel gears 23 or to their coming out of mesh, the radial adjusting movement is superimposed by an axial displacement of the drive bevel gears 23, as is illustrated diagrammatically in FIG. 6.
  • the pitch circle cones 23a of two drive bevel gears 23 are shown before and after adjustment. It can be seen that the drive bevel gears 23 are displaced along the common cone generatrix 31. This necessitates the exact dimensional co-ordination of the radial adjusting movement and the axial displacement.
  • Axial displacement of the drive bevel gears 23 is effected by axially displacing the adjusting bushes 7 in which the drive bevel gears 23 are journalled in an axially fixed manner.
  • FIG. 5 shows how the axial movement of the adjusting bushes 7 is effected. The latter have, in the region of their peripheral surface. a circumferential portion 24 having an external screw thread which receives an internal thread cut into the end faces of two fixed pins 25. A rotational movement ofthe adjusting bushes 7 therefore also causes them to be axially displaced. lt is not necessary for every adjusting bush 7 to have such an external thread 24 if their axial feed movement is transmitted by a bushlike extension 7b or a yoke 10.
  • the embodiment of FIG. 7 basically corresponds to the embodiment of FIG. 3 apart from the additional lay gearing arrangement 26.
  • the working rollers 2 are also adjusted again by means of the radial bearings 6 placed eccentrically in adjusting bushes 7.
  • the rotational movement of the adjusting bushes 7 is effected from the adjusting spindle l8!) by way of a worm gear 27 to the first adjusting bush, the rotational movement being transmitted in the manner already described to the other adjusting bushes 7 by way of the bevel gears ll, the yokes l0 and the bush like extension 7!).
  • Axial adjustment and interchanging of the working rollers 2 is effected in the same manner as in the embodiment of FIG. 1 or 3.
  • FIG. 7 differs from the previously described embodiment mainly in that the drive bevel gears 23 are journalled, not with the roller spin dles 4 and with these eccentrically relative to the peripheral surfaces of the adjusting bushes 7, but in sepa rate radial bearings 28 concentrically relative to the peripheral surfaces of the adjusting bushes 7 and in an axially fixed manner, In contrast to this (see FIG. 8) the radial bearings 6 for the roller spindles 4 are again inserted eccentrically into the adjusting bushes 7.
  • the drive bevel gears 23 therefore maintain, independently of the adjusting movement of the working rollers 2 and the roller spindles 4, their position and not only relative to one another but also within the rolling stand I.
  • the drive bevel gears 23 however have an internal bore 29 which is substantially greater than the external diameter of the roller spindles 4. This is particularly evident from FIG. 9.
  • the roller spindle 4 and with it the working roller 2 can effect a radial adjusting movement independently of the drive bevel gear 23 owing to the eccentric bearing.
  • the clamping part 4b of the roller spindle 4 has an external toothing and a corresponding internal toothing is provided in the bore 29 of the drive bevel gear 23.
  • This toothing, designated 30 in FIG. 9, can if desired be replaced by other torque-transmitting means.
  • a rolling stand as claimed in claim I in which at least one adjusting bush of each roller spindle has a bevel gear by means of which it engages in a corresponding gear of an adjusting bush of an adjacent roller spindle.
  • a rolling stand as claimed in claim I in which the bearings for the roller spindles comprise radial bearings and separate axial bearings.
