Definitions

  • the invention relates, according to the preamble of the claim, to an interchangeable, independent supporting device for pivotable, adjustable and fixable guide element supporting bodies of guide elements for rolling stock for the introduction or execution of rolling stock, in particular shaped steel between the rolls of rolling stands, consisting of transverse to the rolling direction , above and below the rolling line, on uprights of the column stands of the rolling stands, which can be moved up and down by lifting motor drives, with which supporting bodies of the respective guide elements of a pair of guide elements for the rolling stock can be connected in a pivotable, adjustable and fixable manner.
  • Devices of this type serve to change and adjust the position of the two guide elements independently of one another, for example to improve the symmetry of the web of a beam to be rolled, the web of which is acted upon by the guide elements between the rollers of a roll stand or is carried out therefrom.
  • supporting bodies of the guide elements can be moved up and down in a thread-guided manner in a lifting spindles mounted on the outside of the stator spar pairs of the roll stands.
  • the pressure spindles are also arranged on the column spindles driven by a common motor.
  • the guide elements can be pivoted in their respective supports about pivot axes parallel to the rollers; the pivoting position of the guide elements arranged above the roller plane is carried out by a lifting motor which is also arranged on the stator bar and is connected to the guide elements between the pivot axis and the rollers, while the guide elements located below the roller plane rest with their insertion end on the outer circumference of the lower roller.
  • This embodiment of the generic device has the disadvantages that the adjustment of the guide elements must be carried out before the start of the rolling operation if they have already been installed on the rolling stand, ie the rolling operation can only be started when the adjustment of the guide elements has ended .
  • Such adjustment work on the roll stand itself is difficult and time-consuming, because other components which are arranged on the roll stand and do not belong to the rolling stock insertion device must also be dismantled and because the use of auxiliary devices for the adjustment by such work within the rolling mill also makes it difficult or difficult is also made impossible.
  • the object of the invention is to avoid these difficulties and disadvantages and thus to reduce the downtimes of the roll stands that arise when adjusting the guide elements and when replacing them.
  • This solution allows the guide elements to be attached to the additional support beam outside the roller train at a specially equipped assembly location and adjusted before they are connected to the roll stand together with the additional support beam.
  • An additional support beam already on the scaffolding can be exchanged for the additional support beam equipped with the set guide elements.
  • Such an exchange e.g. for a change in the rolling program requires only little time and a few assembly steps on the rolling stand compared to the time required for generic devices and the assembly difficulties.
  • the supporting beam receiving the additional supporting beam is expediently slidably guided with its two ends in guide grooves of the uprights and the additional supporting beam is arranged according to the invention on the side of the supporting beam facing away from the rollers of the roll stand and is plugged onto the latter by means of plug-in pins which can be inserted into plug sleeves.
  • the socket pins can be arranged on the additional supporting beam and, on the side facing away from the supporting beam, have a cantilever extension onto which the supporting bodies of the guide elements having the corresponding receiving recesses can be attached.
  • the support beam can have a bulge protruding between the uprights and completely or partially enclosing the additional support beam in the direction of the rollers of the roll stand, so that the overall depth of both support beams is included the guide elements arranged on the additional supporting beam are kept small in relation to their arrangement in the roll stand.
  • pressure-medium-actuated wedge-type clamping bars acting on the ends of the additional supporting beam can be arranged in the push-on direction of the supporting beam.
  • the rolling stock in the rolling stand 1, in the windows 1a of which the roller pairs 2 indicated by dash-dotted lines are guided between the inner surfaces of the column stanchions 1b and 1c, the rolling stock, not shown, is inserted between the rollers 2 with the aid of the guide elements 3a and 3b or 4a, 4b forming a pair. and executed from these.
  • the pairs of guide elements 3a, 3b and 4a, 4b are articulated with pivot axes 5, 6 lying parallel to the roller to the respective support bodies 7 and 8, which are hook-shaped in cross section, which in turn can be connected to the additional support beams 9 and 10 assigned to them.
  • the additional support beams 9, 10 can be connected to the support beams 16 and 17 guided in the roll stand 1 with T-grooves 14 in T-rails 15.
  • the supporting sheets 16 and 17 have a protruding toward the rolls 2 of the roll stand 1 between the uprights 1b, 1c, according to the Open bulges 16a and 17a on the side facing away from the rollers 2 and are articulated with their two ends 16b and 17b to the side of the uprights 1b and 1c on these articulated lifting motors 18 and 19.
  • connection of the additional support beams 9 and 10, on the one hand, to the support bodies 7, 8 of the guide elements 3a, 3b and, on the other hand, the support beams 16 and 17 is produced in the exemplary embodiment with the aid of a plug pin 21 seated in the additional support beam 9 or 10, which is inserted into a socket 20 can be inserted into the supporting beam 16 or 17, and which has a collar extension 21a, onto which the supporting body 7 or 8 of the guide elements 3a or 3b can be pushed with corresponding receiving recesses, not shown.
  • wedge clamping bolts 24 are arranged in the two ends 16b and 17b of the supporting beams 16 and 17 by means of pressure medium motors 10 provided support surfaces 9b or 10b are applied.
  • the support bodies 7, 8 with the guide elements 3a, 3b can, as can be seen in FIG. 1, by actuating the lifting motors 18, 19, for example, from the position shown in section in the drawing, in which the guide elements 3a, 3b are closely spaced above or below the rolling line W are positioned in the position shown in full lines, in which the guide elements, here 4a, 4b, are positioned at a greater distance from the rolling line W.
  • the additional support beams 9 and 10 are pulled out of the support beams 16 and 17 out of the plug-in sleeves 20 together with the support bodies 7 and 8 and the guide elements 3a, 3b in the direction of the arrow F shown in FIG.
  • the additional support beams 9, 10 prepared there with the support bodies 7, 8 and the already finished guide elements 3a, 3b are plugged onto the support beams 16, 17 with the aid of the plug bolts 21.
  • the release and fixing of the additional support beams 9 and 10 on the support beams 16 and 17 is effected with the aid of the clamping lever 24.
