Definitions

the invention relates to a guide device for four or multi-roll stands with work rolls, back-up rolls and, if necessary. Intermediate back-up rolls arranged between the work rolls and the back-up rolls, in which bending blocks for the bearing chocks of the rolls are guided by pairs of cylinder bars arranged in the windows of the roll stand. the two ends of which are connected directly or indirectly to the roll stand, and between each of which a bending-piston-cylinder unit, which is supported against the upper and lower bending block of the bearing chocks of a pair of rollers, is arranged.
the invention has for its object to improve the known guide device so that larger support distances are possible.
This object is achieved in that the two ends of the cylinder rods are not mounted so as to be displaceable but axially displaceable in the stator windows, one of the cylinder rods of a pair being guided longitudinally displaceably in one of the bending blocks and firmly connected to the other bending block, and the other cylinder rod being fixed are connected to one bending block and are guided so as to be longitudinally displaceable in the other bending block.
the effective support distances of the guide lengths are significantly increased compared to those of comparable known guide devices.
these holding pieces When using, inserted into the window openings of the roll stand, firmly connected to the roll stand and projecting into the window opening, holding pieces for the ends of the cylinder rods, these holding pieces can, according to the invention, have axial displacement bearings for the ends of the cylinder rods; there is, in order to create a horizontal anti-rotation device for the bending blocks, the possibility of arranging sliding plates which can be placed one on top of the other in the side surfaces of the holding pieces and the bending blocks which are assigned to one another. These slide plates, which can be placed one on top of the other, can, as the invention further provides, alternately consist of materials of different structural hardness.
pairs of cylinder guide rods are firmly connected, which are guided parallel to the cylinder rod pairs of the bending blocks of the bearing chocks of the two work rolls and are longitudinally displaceable in the stator-mounted holding pieces.
the guides for the longitudinal displacement of the ends of the cylinder rods can be formed as through openings in the holding pieces and receiving openings for the ends of the cylinder rods can be arranged in the undersides of the bending blocks of the bearing insert of the support rollers facing the through openings.
the lengths of the cylinder rods guided in the stationary holding pieces can be one of the cylinder rod pairs that are fixedly connected to the bending block of the bearing chocks of the upper intermediate roller and that of the cylinder rods of the cylinder rod pair that is connected to the bending block of the bearing insert of the lower intermediate supporting roller be measured differently.
the upper and lower rolls 1 and 2 of the pair of work rolls, supported by the upper and lower support rolls 3 and 4, are mounted in upper and lower bearing chocks 5 and 6, respectively.
the bearing chocks 5 and 6 are laterally gripped by upper and lower bending blocks 8 and 10, which each form a pair.
upper and lower holding pieces 14 and 16 are arranged, each of which protrude into the window 7 and have axial displacement bearings 18 (Fig. 1) in the the cylinder rods 19 of a pair of cylinder rods are inserted with their respective ends 19a (FIG. 3) so as to be longitudinally displaceable.
one (right) cylinder rod 19 sits firmly in the lower bending block 10 and is guided in the upper bending block 8 so as to be longitudinally displaceable, while the other (left) cylinder rod 19, conversely, firmly in the upper bending block 8 is seated and is guided in the lower bending block 10 to be longitudinally displaceable.
Bending-piston-cylinder units 21 are arranged between the cylinder rods 19 of a pair of cylinder rods in the upper and lower bending blocks 8 and 10.
sliding plates 23 and 24 are arranged, as can be seen from FIG. 2, with which the device is secured against the action of rotational forces in horizontal planes .
These sliding plates 23 and 24 have mutually different structural hardness.
a bending piston-cylinder unit 21 ' is also arranged here.
the intermediate support rollers 27, 28 with their bearing chocks 31, 32 are held by pairs of bending blocks 33 and 35, which in turn are each firmly connected to pairs of guide rods (Fig. 9) 37 and 39, which, parallel to the cylinder rods 19 'in the stand-fixed holding pieces 14 ', 16' are guided.
the bending blocks 33 and 35 are acted upon by bending piston-cylinder units 41 and 42 (FIGS. 6, 7 and 9), which are supported against the holding piece 14 'and 16'.
the bending block pairs 33 and 35 for the intermediate support rolls 27, 28 can therefore be actuated and moved independently of the bending block pairs 8 'and 10' of the work rolls 25, 26.
the cylinder rods 37 ′′ and 39 ′′ which are guided longitudinally displaceably in the support pieces 15 ′′, can be dimensioned differently in their lengths L1 and L2, which are guided in the support pieces 14 ′′, which results in a larger support distance corresponding to length L1.
