Definitions

  • the invention relates to a reversible roll stand with pairs of multi-caliber rolls, the bearing chocks in which windows of the stands of the roll stand are formed by spars, and in which the rolls with their bearing chocks can be inserted into a support frame which is between the spars from above can be introduced and removed, and in which the carriers of rolling stock guides can be used.
  • the support frame which accommodates all the rollers with their chocks and the supports of the rolling stock guides arranged on the support frame, takes up as little space as possible within the distance between the two pairs of rollers, so that the distance between the roller pairs can be used as completely as possible for the dimensioning of the bale lengths of the rollers. Any increase in this distance between the spar pairs that is constructively necessary, not because of the length of the bale, but because of the space required by the supporting frame, leads to considerable, in this respect uneconomical, increase in the dimensions of the rolling stand itself.
  • This design of the bearing chocks and the support stand not only requires a considerable amount of work, but also entails a comparatively large dimensioning of the bearing chocks and thus again of the entire rolling stand, because the bearing chocks are visibly weakened by the through-holes and the groove tracks.
  • the invention has for its object to reduce this considerable technical effort; In particular, to avoid the cylindrical guide rods, the through holes for these guide rods and the groove tracks in the bearing chocks and instead to create the possibility to use normal bearing chocks.
  • the support frame consists of a pair of U-shaped plates which are connected to one another in parallel by spacers, in the recesses of which, in the installation position open upwards, the rollers are held with the bearing chocks projecting outwards on both sides
  • the Web area of the U-recesses forms a support surface for the underside of the bearing chocks of the lower roller and the U-recesses of each plate in their opening area have mutually opposite, projecting into the opening lugs, which can be grasped in the expanded position of the carrier lugs arranged on the bearing chocks and which Stands at the top, articulated on their spars, which can be pushed out or swung out for the expansion of the rollers and which have connecting caps bearing the adjusting elements for the bearing chocks.
  • both plates of the pair of plates can have mutually opposite slot recesses for the displaceable insertion of the carriers of the rolling-stock guide guides.
  • the roll stand 1 is formed from the stands 2 and 3 with the spars 2a, 3a and the connecting caps 4 and 5.
  • the connecting caps 4 and 5 are rigidly connected to one another by a crossbar 6.
  • the adjusting spindles 7 are guided in the spindle nuts 8; they are driven together via adjusting gear 8a arranged on the connecting caps 5 and which are coupled to one another via a connecting shaft 9.
  • the upper and lower rollers of the duo roller set here have six caliber channels, which together (see FIG. 1) form the roller calibers indicated there.
  • the bearing pieces 14 of the upper roller 10 and the bearing pieces 15 of the lower roller 11 are (FIG. 2) in the windows formed by the spars 2a, 3a 2c or 3c performed.
  • the bearing pieces 14 hang with hook extensions 14a on a lifting traverse 16, which has a crane eye 16a.
  • the lifting crossbar 16 in turn hangs on lifting cylinders 37 which are connected to the crossbar 6 and is acted upon by the adjusting spindle 7.
  • the lower roller 11 is also guided with its bearing pieces 15 in the windows 2c and 3c of the stands 2 and 3.
  • both parallel-surface plates 17 and 18, in the installed state have opposing slot recesses 21, in which the rolling beams 22, 23 and 24, 25 arranged upstream of the entry and exit sides of the roll nips and the respective rolls can be moved and fixed.
  • six rolling guide guides 26, 27, 28 and 29, respectively are arranged to be adjustable and fixed.
  • outwardly directed cantilever projections 30 are attached in the web area of the U-recesses 20 of the parallel-surface plates 17, 18. These cantilever projections 30 can be placed with their downward-facing surfaces on the lower boundary of the windows 2c, 3c of the roller stands 2, 3 (cf. FIG. 2).
  • the one from the upper roller 10, the lower roller 11, the bearing pieces 14 and 15, the roller beams 22, 23, 24, 25 and the ones mounted and adjusted on them 3, 4 and 5, is held and carried by the parallel-surface plate pair 17, 18 in connection with the lifting cross member 16 and the rolling stock line guide sets 26, 27, 28, 29. It can be lifted up out of the rolling stand 1 from the rolling position shown in FIGS.
  • the upper bearing piece 14 which for this purpose has lateral cantilever projections 33, is held by projections 17a or 18a which project into the opening opposite one another in the opening region of the U-recess 20 after it has been removed from bearing piece 15 was moved away.
  • the cantilever lugs 33 in the place of which, for example, the upper corner edges of the bearing pieces can also occur, underlie the lugs 17a and 18a.
