Definitions

  • Roll support device for correcting the roll gap in a multi-roll mill stand for strips
  • the invention relates to a roll support device for correcting the roll gap in a multi-roll rolling mill for strip material with at least two work rolls and at least one support roll row assigned to each work roll, the support rolls of which are arranged distributed over the entire axial length of the work roll and are rotatably mounted on a support axis. wherein the support of the support rollers assigned to each work roll at least one row of support rollers can be adjusted in a position-changing manner by means of actuators which are effective on the support saddles and comprise wedges or eccentrics.
  • Such a roll support device serves to avoid errors when rolling strips. Errors in the rolling process are due to the fact that the rolling force causes elastic deformations on the loaded roll stand parts. These include, for example, expansion and bending of the roll stand, compression of the adjustment parts, flattening, compression and bending of the rolls, etc. With the roll support device, it is possible to counteract these deformations by the contour of the Roll gap over its width is corrected during the rolling process.
  • each actuator of the support saddles is provided with its own drive.
  • the control paths of the individual actuators are coordinated with one another by means of a control or regulating device.
  • the effort required for the actuators and the control device is correspondingly large.
  • the invention has for its object to provide a roll support device of the type mentioned, with which a correction of the roll gap during the rolling process is made possible with comparatively little effort.
  • This object is achieved in that at least for several actuators at least one row of support rollers, a common actuator is arranged outside the roll stand and the individual actuators are each coupled to the actuator via a transmission element.
  • the desired different change in position on the support calipers can be achieved without control or regulating device with a corresponding dimensioning of the actuators. This is possible because the degree of change in position on the support saddles is steadily decreasing from the center of the scaffold to the edges and the wedges or eccentrics can therefore be appropriately dimensioned differently without difficulty. However, it is also possible to use wedges and eccentrics of the same size instead of wedges and eccentrics of different dimensions if the Travel for the individual wedges and eccentrics is different.
  • the actuator comprises a lever with rods articulated thereon as actuators.
  • the actuator can also comprise an eccentric shaft with rods arranged on it by means of sliding blocks as actuators.
  • the wedges or eccentrics on the support saddles can have the same design. With the same eccentrics of the eccentric shaft, however, they must be designed differently in order to obtain different changes in position on the support saddles over the bandwidth.

  • the roller support device of both exemplary embodiments has an upper and a lower roller set 1, each with 10 rollers or rollers. Both roller sets 1 have the same structure.
  • Several intermediate rolls Z and four rows of support rolls R are assigned to each work roll W1, W2. It can be seen particularly clearly from FIG. 3 that each row of support rollers R comprises a plurality of support rollers 4 which are distributed over the entire axial length of the work roll W1 and are rotatably mounted on a support shaft 3 held in the roll stand 2 of the roll stand, which is not described in more detail.
  • the support shaft 3 is supported on support saddles 5 arranged between the support rollers k and carried by the roll stand 2.
  • the support saddles 5 of the outer support roller rows R can be adjusted by changing the position by means of wedge adjustments K by means of associated adjusting devices.
  • a rod 7 connected to a wedge 6 is used as an actuator K.
  • the adjustment of several actuators K is carried out by a single adjustment drive. From the drawings it can be seen that a separate steep drive 8-19 is provided for each adjustable.
  • the roller support device according to the invention according to FIGS. 1 to 3 is particularly well suited for such a center-weighted correction.
  • the adjustment of the individual actuators K he follows here via two levers 9 » the rods 7 provided with an articulated head 10 are articulated.
  • the levers 9 are each articulated at one end to the lifting cylinder 8 arranged centrally on the roller stand 2 in the axial direction and at their other ends to lifting levers 11 arranged on the roller stand 2 in the axial direction.
  • the lever joints 11 expediently permit displacement in the axial direction, for example through a link.
  • the adjustment of the individual support saddles 5 of a support roller row R is carried out by an alternative roller support device with a rotatably mounted and "arranged on the roller stand 2 eccentric shaft 12.
  • the eccentric shaft 12 is mounted in a plurality of bearings 13, between which the the actual eccentrics 14.
  • the eccentrics 14 lie in corresponding bores 15 of sliding blocks 16, which in turn are connected to the rods 7 are arranged.
  • the arrangement of the scenes 17 in guides 18 allows the rods 7 to move in their axial direction.
  • the actuators K located in the interior of the roll stand 2 correspond exactly to those in the exemplary embodiment previously described with reference to FIGS. 1 to 3
  • the actuators K are adjusted by rotating the eccentric shaft 12.
  • a motor 19 is used for this purpose.
  • the eccentrics 14 of the eccentric shaft 12 can have a different eccentricity to correct the roll gap, but it is also possible for the eccentric shaft 12 has eccentrics 14 only in certain areas, or that the eccentrics 14 are designed so as to be rotationally offset relative to one another with respect to their eccentricity. In this way, a center-weighted correction of the roll gap can also be achieved with the roll support device of the second exemplary embodiment.
  • Actuators K having the support saddles 5 of the outer support rollers 4 and associated wedges 6 can also be provided with actuators assigned to the inner support rollers 4 ' .
  • the change in position can take place by means of eccentrics acting between the support rollers and their support axes 3 or between the support axes 3 and the support saddles
  • Gear drives are adjustable.
  • the gear transmission consists of a pinion connected to the eccentric, which meshes with a toothed rack which, like the rods 7, is driven by a common actuator, in accordance with the two exemplary embodiments.

Abstract

La présente invention se rapporte à un support de cylindres pour la correction de l'écartement des cylindres d'un laminoir à cylindres multiples pour bandes. A cet effet, à chaque cylindre de travail (W1, W2) est associée au moins une rangée de galets de support R comportant des galets de support (4) répartis sur toute la longueur axiale du cylindre de travail (W1, W2) et pouvant tourner sur un axe de support (3) disposé dans le montant de laminoir (2). L'axe de support (3) s'appuie sur des selles de support (5) disposées entre les rouleaux de support (4) et portées par le montant de laminoir (2), la position de ces selles de support pouvant être réglée au moyen de dispositifs de réglage associés, au moyen d'organes de réglage K présentant des cales (6). Afin de corriger avec des efforts relativement minimes l'écartement des cylindres résultant des différentes déformations plastiques, le réglage de plusieurs organes de réglage K se fait par un seul organe correcteur commun (8-11).
