Definitions

  • the invention relates to a cassette roll stand for a pair of duo rolls, whose bearing chocks in one, in a supporting frame and from this removable cassette formed by two stand frames are led.
  • Cassette roll stands of this type are consistently more complete by type Rolling stands, each with their own adjusting devices, and some also own rolling fittings and other carrying and measuring devices educated. They are usually moved into the supporting structure on rails, fixed and aligned there. This complete training, which also used for those for the supporting structure, for the Exchange certain cassette mill stands must be in place technically complex and expensive; it also requires the Pre-assembly of the cassette mill stands to be replaced accordingly high technical effort.
  • the invention has for its object a cassette mill to create that is technically simpler, and its Replacement also requires less effort.
  • the stand frame as above open U-frames formed on their opposite pairs of U-flanges Guides for the bottom roller bearing chocks and one of the U-flange pairs of extension lugs with swivel bearings for the sides of the bearing chocks facing the have upper roller, and that the other, the extension lugs opposite sides of the bearing chocks over resilient Handlebar tappet with the corresponding sides of the bearing chocks connected to the lower roller and adjusting device as well Support and measuring devices for the cassette mill in the Support structure are arranged.
  • the inventive design of the cassette roll stands and The supporting structure leads to a very simple construction of both Cassette roll stands themselves as well as the supporting stand.
  • the technical Effort is further reduced by the fact that the adjusting device and measuring devices only once, namely present in the supporting structure have to be. This also leads to a simplification of maintenance and Adjustment work on the ones prepared for replacement Scaffolding and thus a corresponding reduction in the time required.
  • the two bearing chocks can the upper roller with a swivel crossbeam store connected in the extension lugs of the U-flanges.
  • the supporting structure can consist of an upper and a lower crossbeam, which are connected to each other by tie rods, whereby under the upper traverse a preferably hydraulic adjusting device and on the lower crossbeam the support elements for the cassette roll stand and a pressure cell are arranged.
  • the cassette mill consists of a Stand frame pair, which is formed from open U-frame 1.
  • the opposite pairs of flanges 1a, 1b points one, here 1b, extension lugs 1c and both pairs of flanges 1a and 1b inside guides 1d for the bearing chock 2 of the lower rollers, not shown, of the pair of duo rollers.
  • the sides of the bearing chocks facing the extension lugs 1c 3 are articulated with swivel bearings 5 and one below the other connected by a traverse 6.
  • the extension approaches 5 opposite sides of the bearing chocks 3 are via a handlebar tappet 7 on the corresponding sides of the bearing chocks 2 for the lower roller is articulated.
  • This handlebar tappet 7 consists of a resilient material.
  • the cassette mill is like out Fig. 1 can be seen, used in a supporting structure, which consists of a upper cross member 8 and a lower cross member 9, which by Tie rods 10 are interconnected.
  • the upper traverse 8 carries the adjusting device 11, the chocks 3 for the upper Roller 4 is applied, and on the lower crossmember 9 are Rails 12 for retracting and extending the cassette roll stand and a pressure cell 13 are arranged.
  • the bearing chocks guided in the guides 1d of the U-frame 1 2 of the lower roller are height-adjusted via inserts, not shown and the bearing chocks 3 of the upper roller 4 which, like dash-dotted lines, in the extension lugs 1c of the U-flanges 1b pivotable, are supported by the handlebar tappets 7 on the bearing chocks 2 for the lower roller.
  • the U frame 1 also carries the rolling fittings, not shown. That so equipped cassette roll stand can be used outside of the rolling mill the rollers and roller fittings and set ready for installation will.
  • the cassette mill is placed over the rails 12 pushed into the scaffolding and in this against displacement secured.
  • the adjusting device can then be activated and the two rollers are used to zero the pitch first in contact and then to the desired rolling distance brought.
