Definitions

  • the invention relates to a single-core rolling mill arrangement with a fixed rolling center for rolling wire, fine iron, billets or tubes, which consists of several rolling stands arranged one behind the other, each having driven pairs of work rolls, which form at least two caliber openings, one of which is formed in each Area of the center of the roll is located, top attack of claim 1.
  • Rolling stand arrangements of this type can, as is known (DE-C-2 458 087), by rotating the stand by 180 ° or by pivoting it in a plane lying transversely to the rolling direction and / or by inserting the stand at another appropriately prepared stand, within the stand row the arrangement in the area of the center of the roll and brought out again, with the purpose of switching the roll stand arrangement to another of the caliber openings without changing the roll with little effort and time, as this z. B. is necessary if the rollers forming the calibers are worn or if a program change is to be made.
  • this configuration of the arrangement has the advantage that the caliber openings of the rolls of all roll stands can be brought into the center of the roll in a very short time, so that with such a change there are little downtimes, this arrangement still requires a relatively large amount of work since the complete rolling stands can only be rotated or replaced with the existing crane system one after the other, since not a separate crane is available for each stand.
  • changing the position of a scaffold, in particular the change of location makes it necessary to connect all connections and supply and discharge lines for auxiliary materials such as coolants, lubricants and the like to the scaffold. to solve and reconnect after the change of location or the exchange of space.
  • the object of the invention is to reduce this outlay and to avoid the disadvantages mentioned.
  • this object is achieved according to the invention in a generic Waltz stand arrangement in that the with their bearing chocks as roll sets which are designed to be extendable together from stand guides in the roll stand in the rolling direction, have contact surfaces and lugs for the optional introduction and fixing of the respective roll set both in roll stands for roll pairs with horizontal and in roll stands for roll pairs with vertical axes, the roll stand arrangement having the roll sets their bearing chocks, in the common axial plane of the pair of rollers, can be pivoted through 90 °.
  • This design allows, instead of the complete stands, only to move the roller sets out of the remaining stands with their stand guides, to rotate, to pivot and, if necessary, to insert them into the stand guides of another stand of the arrangement, without thereby changing the stands themselves need, and without having to solve other auxiliary devices connected to the roll stand and feed and discharge lines apart from the drive coupling.
  • the change in the position of the roller sets is carried out using a tipping frame which is assigned to the roll stand arrangement and which receives the roller sets with their bearing chocks and can be pivoted through 90 ° in the common axial plane of the roller pair.
  • the tilting frame can have a pair of receiving bushes for the drive pins of the pair of rollers, which are held by distance-adjustable sliding pieces, and can optionally be arranged on a platform which can be rotated about a vertical axis. Furthermore, as an embodiment of the invention also provides, the possibility of providing distance-adjustable support pieces in a crane crossmember, with which the roll chocks of the roll set can be detachably connected.
  • the roller set 2 located in the stand guides of the roll stand 1, which forms the juxtaposed calibres 3 and 4 can be formed after the drive clutches 5 have been released (not shown) with the aid of the lifting device 6 'consisting of a piston-cylinder unit the roll stand 1 are brought out into the position shown in broken lines, the roll set 2 with its bearing chocks 6, which are connected here by spacer bars 7, being brought out.
  • This roller set 2 is then, as shown in FIG. 2, taken up by the tilting frame 8, which has two sliding pieces 9, which are arranged in the tilting frame 8 by means of spindles 10, and a receiving bush 11 each wear into which the drive pin 2a of the roller set 2 can be inserted in a manner not shown by horizontal movement of the roller set 2.
  • the tilting frame 8 is then tilted about the horizontal axis 12 with the aid of the lifting motor 14 engaging the lever 13 by 90 ° into the position shown in dash-dotted lines and by means of eyebolts 15 arranged on the bearing chocks 6 facing away from the drive pins 2a with the supporting pieces 16 by means of clamping bolts 18 connected.
  • the support pieces 16 are slidably adjustable in distance in the crane traverse 18 hanging on the crane hook 19 on a slide guide 20 by means of the spindles 21.
  • roller set 2 brought in this way from the horizontal axis position into the vertical axis position is, as can be seen from FIG. 3, introduced into the roll stand 21 'for roll pairs with a vertically lying axis in a manner analogous to that from the roll stand 1 according to FIG. 1 has been extended, and it is only necessary to connect the drive pins 2a to the available couplings 22 of this roll stand 21 '.
