Definitions

  • the invention relates to a roll stand with an adjustable (on the fly) interchangeably mounted roller support shaft on a double-sided adjustable roller support shaft pair, in which both roller support shafts have pin projections projecting beyond the roller rings, onto which each pin bearing can be pushed and fixed, while both bearing housings can take up rolling forces are non-positively connectable.
  • 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 by spur gears and intermediate drive shafts or articulated spindles, are known (DE-PS 736 879, 1 427974 and 910102).
  • the rolling rings are placed on the free journals of the roll 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 lines, 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.
  • journal bearings can be positively connected to a pair of adjusting eccentric bushes mounted in a common housing.
  • these adjusting eccentric bushes of the supporting shaft pair can be detachably rotatably coupled to the adjusting eccentric bushes receiving the journal bearings.
  • This eccentric bushes and the adjusting eccentric bushes of the pair of roller drive shafts can be rotatably coupled.
  • This rotary coupling can consist in that the adjusting eccentric bushes of the pair of roller drive shafts each have a segment approach projecting axially parallel over the respective journal supporting the rollers, which can be inserted into a flange provided on the associated eccentric bushing of the journal bearing.
  • the outer rings of the journal bearing 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 which 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, independently 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 actuating elements can be piston-cylinder units which are driven directly or via pressure intensifiers and acted upon by pressure medium and are determined by position transmitters. 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 are connected in a manner known per se to a spindle driven by a hydraulic motor.
  • the bearing housings can be connected by tie rods, which form the piston rods of a pair of piston-cylinder units, with one (lower) bearing housing being suspended in the pull rods and the other (upper) bearing housing, carrying the piston-cylinder units, sliding guides for the Has tie rods.
  • the bearing housings are expediently designed in the form of roller bearing chocks with mutually facing, spacing-defining support lugs. Zvi -. Beautiful the mutually facing sides of the bearing housings, particularly lage.reinbau consortiumen in the form of roller, can on to that of Orderly, interchangeable, replaceable or adjustable spacers can be introduced.
  • the exchange of the rolling rings for other rolling rings can be carried out according to a further development feature 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 at axial spacing of the rolling rings of a pair of rolling rings one above the other and horizontally offset by 180 ° for them Has rolling rings.
  • the bearing housing can also form the support frame itself.
  • roller bearing shafts postponing and fixing the roller bearing shafts to the pin projections projecting beyond the roller rings, and to connect their bearing housing for receiving rolling forces in a form-fitting manner
  • roller straighteners apply advantageously.
  • connection of the bearing housings in the various forms of construction described makes 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 with one another connected roll stands was the case.
  • roll stands with particularly high rigidity, e.g. B. such can be used with eccentric bushing, and the relatively small dimensions allow the stands to move closer together in the rolling direction.
  • the compact design that can be achieved in this way also makes it easier to modernize existing rolling mills where space is limited.
  • 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 sit 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.
  • These eccentric bushes 22a, 22b are detachably rotatably coupled to the adjusting eccentric bushes 23a, 23b of the pair of roller support shafts 2 in such a way that the adjusting eccentric bushes 23a, 23b each have a segment projection 23a ', 23b' projecting axially parallel to the respective roller journal 2b an attachment flange 22a 'or 22b' arranged on the associated eccentric bushing 22a or 22b of the journal bearing 11 or 12 can be inserted.
  • the eccentric bushes 22a, 22b therefore make the rotational 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 adjusting positions of the roller supporting 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 effect the adjusting movements the roller support shafts 2, which are driven via couplings 6a de on their journals 2a, indicated by dash-dotted lines, by means of toothed gears 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 supporting shafts have pin projections 2c 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 supporting 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 stand 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 pin bosses 2c and fixed with the help of the axial securing elements 13. Analogously vice versa, the rolling rings 8 can be pushed from the position shown in dash-dotted lines in FIG.
  • 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.
