Definitions

  • the invention relates to a roll stand with a support shaft pair mounted on two sides and adjustable in two parallel roll stands and which can be coupled on one side with drive elements, for roll rings which can be pushed onto a seat between the two roll stands.
  • 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 a lot of stress on the roll material, e.g. in the finished blocks of modern roller mills.
  • the advantage of these rolling stands is that only the rolling ring has to be made of, for example, highly wear-resistant and heat-resistant material, while the support shafts only have to be made of a material that can withstand the secondary stresses, for example the bending forces resulting from the rolling pressure .
  • rollers of greater weight e.g. In the preliminary stages of wire rolling mills or in billet or other form steel mills, one has either exchanged a complete stand for the other for the roll change or only the respective roll sets with their bearing chocks, usually held together by a cassette, can be moved out of the stands. and designed to be interchangeable. Solid material rolls without sliding ring rings were used throughout.
  • the invention has for its object to improve the generic roll stands so that even with larger stand dimensions, such as are necessary for billet steel or other roll trains, roller support shafts can be used with roller rings, and the roller rings are replaced can, without the need to move or dismantle the entire rolling stand.
  • roller stand facing away from the drive elements of the support rollers with the bearings removed from the support shaft pair can be moved in a manner known per se roller axially in the direction away from the other roller stand, and the support shaft pair in the resulting cantilevered cantilever position other roll stand can be held and fixed.
  • adjustable and lockable support surfaces can be arranged in the non-moving roller stand for support surfaces that can be placed on the support shaft between the bearing of this roller stand and the drive elements of the support shafts, which facilitate their holding and fixing.
  • Retaining elements which can be connected and detached to the roller rings can be arranged on the movable roller stand, for example, from the support shaft which is connected to the inner ring of the bearing slide-on bushing exist, on the outer circumference of which the rolling ring can be pushed.
  • the bushing can be designed in a manner known per se as a split, slotted or undivided journal bushing with a conical inner circumferential surface and a cylindrical outer circumferential surface.
  • the journal sleeve can also have a ring shoulder forming the inner ring of the bearing.
  • the eccentric bushes can pass into a cylindrical extension comprising the support shaft, the ring end of which faces the drive elements of the support shafts and forms an axially inwardly directed collar which forms an annular support surface for the support shaft section to be placed .
  • the adjusting devices of both roller stands are appropriately coupled together.
  • the roll fittings common to the two roll stands can be carried by the movable roll stand and fastened to it, and can be plug-connected to the other roll stand.
  • the invention further provides a carrier carriage for the movable roller stand, which has a pair of support bolts which can be moved into the shaft openings of both bearings of the roller stand and which can be fused and fixed on the carrier carriage by means of an adjusting device corresponding to the adjusting device of the roller stand.
  • a turntable can be arranged in front of the roll stand on the operator side in order to receive the carrier cars.
  • a plurality of these turntables can also be arranged on a carousel cross, as the invention further provides, the distance between the pivot points of successive turntables on the carousel cross being dimensioned such that they can each be introduced into the extensions of the axis line of successive roll stands of a roll train, for example as follows that the pivot points each half of the turntables arranged on the carousel cross can simultaneously be aligned to the corresponding number of successive roll stands.
  • the wagons can have their 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 located in eccentric bushes 9 and 10, which in turn are rotatably mounted in the roller stands 1 and 2 and form the adjusting device for the support shafts 3, 4.
  • the eccentric bushing 10 in the roll stand 1 projects with a ring segment section 10a over the respective rolling ring 15 and is plug-connected to a corresponding ring extension 9a of the other eccentric bushing with the effect that when turning the eccentric bushes 10 by means of a threaded spindle 12 in the roller stand 1, this rotation is transmitted to the eccentric bushing 9.
  • the eccentric bushing 10 arranged in the roll stand 1 merges into a cylindrical extension 10b which comprises the support shaft 3, 4 and whose ring end facing the drive clutch 16 has an inwardly directed collar 10c which has a cylindrical support surface 10d for the section of the support shaft 3, 4 forms between the bearing 6 and the drive clutch 16.
  • the roll stand 2 of the roll stand 1, 2 is moved away from the roll stand 1 in the direction of the arrow shown in FIG. 3 by loosening the screw connections 8 with the aid of the support carriage 18 shown on FIG .
  • 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 and held in their withdrawal position.
  • As a holding element support bolts 30, which are used in the. Pull-off movement of the carriage 18 occurs in the bearing openings of the bearing 5 which 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.
  • the carrier carriages 18 can run over pairs of rails 26 the turntables 21 of a carousel cross 25 are applied, as shown in the exemplary embodiment, four carrying carriages 18 at the same time or in succession if the distance between the fulcrums of successive turntables 21 on the carousel cross 25 is dimensioned such that these fulcrums have been introduced into the extensions of the axis lines of successive roll stands A, B, C, D of the roll train.
  • half of the turntables 21 arranged on the carousel cross 25 can be aligned simultaneously with the successive four rolling mill bags A, B, CD.
  • the carrier cars 18 can move up and down on the turntables 21 independently via the pairs of rails 26.
