Definitions

  • the invention relates to a multi-roll stand with two back-up rolls and two work rolls mounted in each case by means of chocks in windows of the roll stand, in which the work rolls are carried by the driven back-up rolls by friction drive and are shifted to their horizontal support from the vertical axis plane of the back-up rolls, with in the roll gap between the bales of the two work rolls, the rolling strip underlying the rolling process is arranged - four-roll stand -.
  • the invention also relates to a multi-roll stand with two backup rolls, two intermediate rolls and two work rolls, each mounted by means of chocks in the windows of the roll stand, in which the work rolls are driven by friction from the intermediate rolls, which are either driven directly or by the driven support rolls Friction drive are taken along and are shifted to their horizontal support from the vertical axis plane of the backup rolls and the intermediate rolls, the rolling strip underlying the rolling process being arranged in the roll gap between the bales of the two work rolls - six-roll stand -.
  • Such multi-roll stands are mainly used in the cold forming of strip material because they advantageously allow the use of work rolls with a small bale diameter.
  • the invention aims on the one hand to eliminate the disadvantages peculiar to the known multi-roll stands of the type specified at the outset. On the other hand, it should also overcome the disadvantages of roll stands that are only compensated by lateral force and without lateral support.
  • the object on which the invention is based is therefore to create a multi-roll stand of the generic type for the use of slim work rolls, which counteracts the occurrence of malfunctions and roll damage with minimal technical effort, even if belt breaks occur.
  • this object is achieved in a four-roll mill stand in that the bales of the work rolls with their wide end sections protrude beyond the longitudinal edges of the rolled strip and the bale ends of the backup rolls, so that these end sections of the bale of the work rolls are at least on that side , according to which the axis plane of the work rolls is offset with respect to the axis plane of the support rolls, support rolls or rolls or also hydrostatic support saddles are assigned, and that each support roll or roll or also each support saddle is essentially horizontal and parallel to the rolling direction outside the Rolling width can be adjusted against the end sections of the bales of the work rolls.
  • the object is achieved in that the bales of the work rolls with their two end sections protrude beyond the longitudinal edges of the rolled strip and at least also over the bale ends of the support rolls, that these end sections of the bale Work rolls at least on the side towards which the axis plane of the work rolls is opposite the axis plane of the backup rolls and the intermediate rolls is arranged offset, support rollers or rollers or hydrostatic support saddles are assigned, and that each support roller or roller or also each support saddle can be adjusted essentially horizontally and parallel to the rolling direction outside the rolling band width against the end sections of the bales of the work rolls.
  • the rollers are also not suitable for driving the work rolls. Rather, the work rolls are driven directly here. From this it can be deduced that in the known roll stand the work rolls must have a certain minimum diameter in order to be able to absorb the driving force safely over the entire length.
  • the work rolls are arranged in a common vertical axis plane with the support rollers, which in turn is an obstacle to the use of very slim work rolls.
  • the work rolls are also not stored in the windows of the roll stands by means of chocks. Rather, the support rollers arranged in the common axial plane with these support rollers interact with additional rollers, which only act on the roller journals which are turned away from the drive side thereof with a horizontal direction of action. With their help, however, the work rolls cannot be bent horizontally.
  • a multi-roll stand according to the invention has the advantage that malfunctions or roll damage cannot occur either in the case of belt breakers, or in the event of operating errors, start-up errors or incorrect connection of belt pulls.
  • each work roll at least on the side towards which the axis plane of the work rolls is offset with respect to the axis plane of the backup rolls or also the intermediate rolls, two support rolls or rolls or support saddles are also assigned, and that the side distance between these support rollers can be adjusted over a range that extends at least from the maximum rolling strip width to the minimum rolling strip width.
  • the work rolls are supported on their circumference of the bale in the vicinity of the strip edges of the rolled strip, preferably where there is no contact between the bales of the work rolls and the rolled strip.
  • the support rolls or rolls or support saddles can be displaced transversely to the rolling direction along the bale of the work roll up to the roll contact area thereof to the roll belt .
  • the construction of a multi-roll stand according to the invention has the advantage that the work rolls can be easily lubricated and cooled from both sides.
  • each guide crossmember can carry the two support rollers or rollers or support saddles assigned to a work roll.
  • a multi-roll stand is also characterized in that the adjusting drive for the guide cross members is formed by hydraulic cylinders, while mechanical drives with threaded spindles and adjusting nuts are provided on the guide cross members for longitudinal adjustment of the support rollers or rolls or support saddles.
  • a multi-roll stand according to the invention can not only be used for normal four-roll and six-roll roll stands, but can also be used when such multi-roll stands are equipped with so-called bottle rolls. They can not only be used as single-use and reversing scaffolding, but can also be used in tandem streets.
  • the multi-roll stands according to the invention can also be used when working with positive and negative vertical work roll bending.
  • the back-up rolls do not have to be driven, but the intermediate rolls can also receive this drive, whereby then not only the work rolls but also the backup rolls are taken along by these intermediate rolls by friction drive.
  • multi-roll stands according to the invention can also be used with work rolls, back-up rolls and, if appropriate, which can be moved transversely to the rolling direction. also equip intermediate rollers.
  • the multi-roll stand according to FIG. 1 has - for the sake of simplicity only partially shown roll stand 1, in the windows 2 of which - in the usual way - not shown - chocks are guided, in each of which an upper support roll 3 'and a lower support roll 3 "of a support roll set on one common vertical axis plane 4-4. Both support rollers 3 'and 3 "of the support roller set 3 are driven in rotation and each take with them by friction drive work rollers 5' and 5" of a work roller set 5, which are likewise arranged on a common, vertical axis plane 6-6 are.
  • the axis plane 6-6 of the work roll set 5 consisting of the two work rolls 5 'and 5 "is offset in the rolling direction with respect to the axis plane 4-4 of the two support rolls 3', 3" of the support roll set 3, with each work roll 5 'and 5 " in two chocks 7 ', 7 ", as can be seen from FIGS. 1 and 2.
  • the bale diameters of the two work rolls 5 'and 5 are significantly smaller than the bale diameters of the two support rolls 3' and 3". However, the bales of the two work rolls 5 'and 5 "have a greater length than the bales of the two support rolls 3' and 3".
  • bale length of the two support rollers 3 'and 3 “needs to be dimensioned only slightly larger than the maximum roll width
  • the bale length of the two work rolls 5' and 5" is dimensioned such that it projects beyond the maximum roll width on both sides.
  • the roll bales of the two work rolls 5 'and 5 "of the work roll set 5 are each assigned special support rollers 8' or 8" in the area of the two bale sections protruding beyond the maximum roll width, at least on that side, according to which the axis plane 6-6 of the work roll pair 5 are offset from the axis plane 4-4 of the support roller pair 3.
  • bale sections of the two work rollers 5' and 5" projecting beyond the maximum rolling band width can also be assigned "support rollers 9 'and 9".
  • the direction of passage of the rolled strip through the multi-roll stand is indicated by the arrows 10 in FIG. 1.
  • the support rollers 8 ', 8 "or 9', 9" are only brought into action on the outlet side, only on the inlet side or both the inlet side and the outlet side in such a way that they act on the relevant bale end sections of the work rolls 5 'and 5 "in such a way that they run continuously depends essentially on the bale diameter of these work rolls 5 'and 5 "and / or also on the multi-roll stand being operated as a one-way stand or as a reversing stand.
  • the support rollers 8 ', 8 “or 9', 9” acting on the bale sections of the work rolls 5 'and 5 "lying outside the maximum roll band width can not only avoid malfunctions of the multi-roll stand and damage to the work rolls 5', 5", but they can also be used to force the work rolls 5 'and 5 "in the area between the chocks 7' and 7" supporting them to have a substantially horizontal bending deformation over the length of the roll bales.
  • each individual support roll 8', 8" or 9 is shown in FIGS ', 9 "assigned a horizontal adjusting device 11, which can be acted upon by hydraulic cylinders with the necessary bending forces, for example.
  • the multi-roll stand according to FIG. 2 basically has the same structure and the same mode of operation as the multi-roll stand according to FIG. 1. The only difference is that the multi-roll stand according to FIG. 2 each between the support roll 3 'or 3 "and the associated work roll 5 'or 5 "still has an intermediate roll 12' or 12".
  • the two intermediate rolls 12 'and 12 are preferably arranged on the same vertical axis plane 4-4 as the two support rolls 3' and 3", while the work rolls 5 'and 5 "lie on the vertical axis plane 6-6, which is offset towards the outlet side of the stand.
  • the multi-roll stand according to FIG. 2 completely corresponds to that according to FIG. 1.
  • the side distance 13 between the two support rollers 8 ', 8 "or 9' or 9" assigned to the same work roll 5 'or 5 " is fixed, and corresponds approximately to the maximum roll width 4 to 7 show an embodiment of a multi-roll stand, the basic structure of which corresponds to the multi-roll stand according to FIG. 1.
  • the multi-roll stand according to FIGS. 4 to 7 is thus - like the multi-roll stand according to FIG. 1 - designed as a four-roll stand, i. H. it has two driven support rollers 3 'and 3 "as well as two work rollers 5' and 5" carried along by friction drive.
  • the two backup rolls 3 'and 3 are in turn on a common vertical axis plane 4-4, while the work rolls 5' and 5" have a common vertical axis plane 6-6, which is offset from the axis plane 4-4 towards the outlet side of the multi-roll stand , as can be seen from the arrow 10, which indicates the direction of the rolling stock.
  • the work roll 5 ' is assigned two support rollers 8' and the work roll 5 "two support rolls 8", as is indicated in FIGS. 4 and 5.
  • the work roll 5 ' can also be assigned two support rollers 9' and the work roll 5 "two support rolls 9", as can also be seen in FIGS. 4 and 5 by dashed lines.
  • FIG. 5 it can clearly be seen from the work roll 5 "that the work rolls 5 'and 5" have a much larger bale length than the associated support rolls 3', 3 ", of which only the support roll 3" in FIG. 5 is through dash-dotted lines - is indicated.
  • bale length of the two support rolls 3 'and 3 is matched to the maximum roll width, i.e. it is preferably dimensioned somewhat larger than the maximum roll width.
