Definitions

  • the invention relates to a roll stand with roll rings which are interchangeably mounted on one side (overhung) on a double-sided adjustable roller support shaft pair.
  • Roll stands of this type in which the pair of roller drive shafts are supported, for example, in rotatable eccentric bushes belonging to the adjusting device and are driven via spur gears and intermediate drive shafts or articulated spindles, are known (DE-PS 736 879, 1 427 974 and 910 102).
  • the rolling rings are placed on the free journals of the roller supporting shafts and fixed there.
  • the rolling rings are relatively small; some of them can can be changed manually without the help of a crane.
  • Such scaffolds are primarily used in the prefabricated block of wire mills, since the rolling forces are relatively low there and the one-sided mounting does not pose any difficulties.
  • the invention has for its object to improve roll stands of the generic design so that they are able to absorb significantly larger rolling forces despite one-sided mounting of the rolling rings.
  • both roller support shafts have projecting pin lugs beyond the roller rings, onto which pin bearings can be pushed and fixed, the bearing housings of which are non-positively and / or positively connected to absorb rolling forces.
  • the journal bearings can be arranged together in a one-piece housing and an adjusting device can be assigned to each journal bearing.
  • the adjusting devices are designed in a manner known per se as eccentric bushes which are rotatably mounted in the common housing and receive the journal bearings, and these can Eccentric bushes and the adjusting eccentric bushes of the pair of roller drive shafts can be detachably and rotatably coupled.
  • This rotary coupling can consist in that the adjusting eccentric bushes of the pair of roller support shafts each have an axially parallel segment shoulder projecting beyond the respective journal bearing the rollers, which can be inserted into an attachment flange arranged on the associated eccentric bushing of the journal bearing.
  • the outer rings of the journal bearings and / or the bearings of the pair of supporting shafts can even form the eccentric bushes.
  • bearing housings there is also the possibility of connecting the bearing housings by actuating elements that can be pressurized and can be moved parallel to the direction of attack of the roller support shafts.
  • Both bearing housings can be arranged in a common support frame. This support frame or the one-piece housing can be displaceable in the direction of the roll axis and / or transversely to it, regardless of the roll stand receiving the roll support shafts.
  • the actuating elements should be able to be moved and fixed synchronously with the actuating elements of the adjusting device arranged in the roll stand, which move the roller supporting shafts in the adjusting direction.
  • the adjusting elements for the adjustment of the roller support shafts can also be connected to the adjusting elements for the adjustment of the journal bearings by detachable rotary plug elements and, if necessary, driven directly or by pressure intensifiers of piston-cylinder units, which are determined by position sensors. It is also advantageous to use sliding wedge pairs which act on the adjusting elements in the direction of adjustment and can be moved towards and away from one another transversely to the rolling direction and which, in a manner known per se, are driven by a hydraulic motor Spindle are connected.
  • the bearing housings can be connected by tie rods, which form piston rods of a pair of piston-cylinder units, one (lower) bearing housing being arranged hanging in the tie rods, and the other (upper) bearing housing, carrying the piston-cylinder units, sliding guides for which has tie rods.
  • the bearing housings are expediently designed in the form of roller bearing chocks with mutually facing, spacing-defining support lugs. Between the mutually facing sides of the bearing housings, in particular in the form of roller bearing chocks, spacers that can be placed, exchanged or placed on these bearing surfaces can be introduced.
  • the exchange of the rolling rings for other rolling rings can be carried out according to a further proposal of the invention with the aid of a support frame which can be rotated about a vertical axis, can be moved in a hanging or rolling manner, and which is arranged in pairs in the axial spacing of the rolling rings of a pair of rolling rings one above the other and horizontally ! 180 0 rotatably offset trunnion for these rolling rings.
  • the bearing housing can also form the support frame itself.
  • connection of the bearing housings in the various forms of construction described make it possible to absorb the essential part of the rolling forces in the case of one-sided mounting of the rolling rings, as has hitherto only been the case with the known double-sided mounting on both sides of the roll or of the rolling ring in normal roll stands with two cross members interconnected roll stands was the case.
  • the compact design that can be achieved in this way also makes it easier to modernize existing rolling mills where space is limited.
  • the roll stand can be used both as a stationary stand and as a changeable stand, for example, extendable or removable in the rolling mill.
  • Rolling rings with multiple calibers can also be used.
  • the roller support shafts 2 are mounted in the stands 3a and 3b of the roll stand 3 in pitch eccentric bushes 23a and 23b in bearings 5a and 5b.
  • the eccentric bushes which are formed in one piece here, can be rotated with the aid of the spindle 35 and thereby bring about the positioning movements of the roller support shafts 2, which are driven by articulated spindles (not shown) via the couplings 6a placed on their pins 2a.
  • a rolling ring 8 is slid onto each of the studs 2b of the supporting shafts 2 projecting from the stand 3a of the roll stand.
  • the support shafts 2 have pin projections 2c projecting beyond the roller rings 8, onto which the one-piece housing 21 with the pin bearings 11 and 12 is pushed and fixed by axial securing elements 13 which are seated on a further outer pin extension 2d of the roller support shafts 2.
  • Each of the journal bearings 11 and 12 is assigned an adjusting device which also consists of eccentric bushes 22a, 22b which are rotatably mounted in the common housing 21 and accommodate the journal bearings 11 and 12.
  • eccentric bushes 22a, 22b are detachably rotatably coupled with the adjusting eccentric bushes 23a, 23b of the support roller pair 2 in such a way that the adjusting eccentric bushings 23a, 23b each have a segment projection 23a ', 23b' projecting axially parallel to the respective roller journal 2b, which in one, at the the associated eccentric bushing 22a or 22b of the journal bearing 11 or 12, the attachment flange 22a 'or 22b' can be inserted.
  • the eccentric bushes 22a, 22b therefore make the rotary movement of the adjusting eccentric bushes 23a, 23b in the assembled state of the roll stand described, so that the journal bearings 11 and 12 follow the changes in the positions of the roller support shafts 2.
  • roller support shafts 2 are also supported in the stands 3a and 3b of the roll stand 3 in eccentric bushes 4a, 4b in bearings 5a, 5b.
  • the eccentric bushes 4a and 4b can be rotated in a manner not shown here with the aid of adjusting elements and thereby bring about the adjusting movements of the roller support shafts 2, which are dash-dotted by couplings 6a placed on their pins 2a indicated articulated spindles 6 are driven via gear 7.
  • a rolling ring 8 is pushed onto each of the pins 2b of the supporting shafts 2 projecting from the stand 3a of the roll stand 3.
  • the support shafts have pin projections 2 projecting beyond the roller rings 8, onto which the bearing housings with the bearings 11 and 12, which are designed here as roller chocks 9 and 10, are pushed on and are also fixed by axial securing elements 13 which are attached to a further, outer pin extension 2d of the roller support shafts 2 sit.
  • 9 piston-cylinder units 15 are arranged in the upper roller chock, the piston rods 16 of which slide in the chock 9 and carry the lower chock 10 with their end sections.
  • the chocks 9 and 10 are provided with distance-determining support lugs 9a and 10a.
  • the rolling rings 8 can be placed on the rolling stands 3 placed on the supporting stands 20a arranged one above the other on a supporting frame 20 on the supporting shafts 2 or the spigot extensions 2c and on the spigot extensions 2b in the position shown in broken lines are brought. Then the two bearing chocks 9 and 10 are pushed onto the journal lugs 2c and fixed with the aid of the axial securing elements 13. Analogously vice versa, the roller rings 8 can be pushed onto the support pins 20a of the support frame 20 from the position indicated by dash-dotted lines in FIG. 5 and then arranged on the other side of the support frame 20 after rotating the support frame by 180 ° Replacement roller rings 20a 'are brought into the slide-on position and are pushed onto the pin extensions 2b of the roller support shafts 2.
  • sliding wedges 25a and 25b are arranged between the bearing housings, which are also formed here as chocks 9 and 10, and their wedge surfaces bear against the chocks 9 and 10 by means of a spindle 26, which is driven by a hydraulic motor 27 is driven, are movable towards and away from each other.
