Definitions

  • the invention relates to a rolling stand with a pair of support shafts arranged in two-sided, adjustable bearings and on one side that can be coupled with drive elements, and on the support shafts of which push-fit roller rings can be pushed into a seat between the two bearings, in which the bearings facing away from the drive elements in an independent carrier and with the latter can be moved away from the roll stand in the direction of the roll axis, the support shafts being able to be retained in the roll stand in the resulting one-sided support position.
  • Roll stands of this type are mainly used where the actual roll body has to consist of particularly high-quality materials, because the rolling process takes place at high speed, under high temperatures and / or other influences that put very heavy stress on the rolling material, e.g. in the finished blocks of modern wire rolling mills.
  • the advantage of this rolling stand is that only the rolling ring on e.g. highly wear-resistant and heat-resistant material must exist, while the support shafts only have to be made of a material that can withstand the secondary stresses, e.g. must be able to withstand the bending forces resulting from the rolling pressure.
  • the invention lies
  • the object of the invention is to improve the roll stands of the generic type in such a way that roller support shafts with roll rings can also be used with larger stand dimensions, as are necessary for billet and form steel and also other roll trains, and the roll rings can be replaced without any displacement or disassembly of the entire mill stand.
  • the rolling stand is designed as a two-stand stand with a movable stand which can be moved away from the stand on the drive side and can be placed on a carrier carriage, which stand can be connected to the rolling rings and has holding elements which can be released from them in the moved-away position, wherein the drive-side stand has adjustable and fixable support surfaces for support surfaces which can be placed thereon of the section of this support shaft located between the bearing in this stand and the drive element of the support shaft.
  • This design of the roll stand allows the roller stand bearing the bearing, facing away from the drive, to be moved out in one movement together with the roller rings pulled away from the support shafts, the support shafts being provided in their cantilevered position by the support and support surfaces provided between the drive side roller stand and the drive elements be held.
  • the rolling stand mentioned publication (AT-B-181 483) no precautions to hold the supporting shafts in the supporting position when the rolling rings are removed, and the bearing bracket cannot be placed on a carriage; it also has no holding elements that can be connected and detached to the rolling rings, because it must rather be completely removed and removed from the ends of the supporting shafts before the rolling rings can be removed from these supporting shafts.
  • the holding elements can consist of a bushing, which is connected to the inner ring of the bearing and can be pushed onto the supporting shaft, on the outer circumference of which the rolling ring can be pushed.
  • the bushing can be designed as a split, slotted or undivided spigot with a conical inner circumferential surface and a cylindrical outer circumferential surface and the spigot can have a ring shoulder which forms the inner ring of the bearing.
  • the carrier carriage for the movable stand can have a pair of support bolts which can be moved into the shaft openings of both bearings of this stand and which can be positioned and fixed on the support shafts by means of an adjusting device corresponding to the direction of adjustment of the stand.
  • the carrier can advantageously have its own drive units.
  • the roll stand consists of the stationary with a base 1a connected in a manner not shown to the rolling floor roll stand 1 and the roller stand 2 screwed onto the base 1a by means of a screw connection 8 in both roll stands 1 and 2 the supporting shafts 3 and 4 of the pair of supporting shafts are supported in bearings 5 and 6, respectively; they have a threaded shoulder 3a or 4a on the end facing the roller stand 2, onto which a nut 7 is screwed in each case.
  • the bearings 5 and 6 are each in eccentric bushes 9 and 10, which in turn are rotatably mounted in the roll stands 1 and 2 and form the adjusting device for the support shafts 3, 4.
  • the eccentric bushing 10 in the roller stand 1 projects with a ring segment section 10a over the respective rolling ring 15 and is plug-connected to a corresponding ring shoulder 9a of the other eccentric bushing with the effect that when the eccentric bushings 10 are rotated by means of a threaded spindle 12 in the roller stand 1, this rotation onto the eccentric bushing 9 is transmitted.
  • the eccentric bushing 10 arranged in the roll stand 1 merges into a cylindrical extension 10b comprising the supporting shaft 3, 4, the ring end of which facing the drive clutch 16 has an inwardly directed collar 10c which has a cylindrical support surface 10d for the section of the supporting shaft 3, 4 between the bearing 6 and the drive clutch 16 forms.
  • the roller stand 2 of the roll stand 1, 2 is moved away from the roller stand 1 in the direction of the arrow shown in the direction of the arrow shown and thus the bearings 5 from after loosening the screw connections 8 with the aid of the carriage 18 which can be moved on rollers 20 with the aid of a drive unit (not shown) deducted the support shafts 3, 4.
  • the rolling rings 15 are seated on the cylindrical outer surface 22a of bushes 22, with a conical inner surface 22b. These bushes 22 simultaneously form the bearing inner ring of the bearing 5. The rolling rings 15 are therefore brought out of the roll stand together with the roll stand 2 in this embodiment and held in their withdrawal position.
  • Support bolts 30 serve as the holding element, which, when the carriage 18 is pulled off, enter the bearing openings of the bearings 5 that are released in the process. These support bolts 30 can be aligned to the respective position of the bearings 5 or the bushings 22 with the aid of the adjusting devices arranged on the support carriage 18.
