Definitions
- Roll stand with crossed support and / or work rolls
- the invention relates to a roll stand with support and / or work rolls for rolling sheets and strips, in which the upper and lower work rolls, if necessary together with the support rolls assigned to them, by pairwise horizontal displacement of the chocks stored within the stand window from the common Vertical plane can be shifted into positions in which the vertical planes running through the roll axes of the work and backup rolls intersect.
- European patent application 0 525 552 A1 proposes common sliding blocks for the chocks of the work and back-up rolls, which are arranged between the chocks and the roll stand and have wedge surfaces on their sides facing away from the chocks, which have vertically adjustable displacement drives with the same wedge surfaces correspond.
- the wedge surfaces sliding on one another cause a horizontal displacement of the sliding blocks, as a result of which they adjust the chocks lying on the side and the rollers are crossed in pairs.
- actuators have also become known from the same document, such as hydraulic cylinders or spindles acting mechanically on the chocks, with which the chocks are shifted horizontally within the stand window in order to change the roller positions.
- the object of the present invention is to provide a roll stand with simple displacement drives and high system stability, which enables simple rolling of the rolls with conventional bearings .
- each pair of rollers formed from the upper and lower support and work rolls with its Roll chocks are received in one of two cassettes that extend horizontally into the double-sided stator window of the roll stand and are vertically and / or horizontally adjustable in such a way that the cassettes can be pivoted in opposite directions about a common central vertical axis provided by the stator cross member and on the cassette upper and lower
- each cassette is supported vertically against the rolling stand frame in the area of the stand window by means of pendulum supports gimbally mounted at both ends.
- the invention is also applicable when a so-called duo rolling mill with only two
- each work roll with its roll chocks is accommodated in one of two cassettes which extend horizontally into the double-sided stand window of the roll stand and is vertically and / or horizontally adjustable in such a way that the cassettes rotate in opposite directions about a common central vertical axis are pivotable, which is formed by the upper and lower centering pin bearings provided on the stator cross member and on the cassette and that each cassette is supported vertically against the rolling frame in the area of the stator window by means of pendulum supports mounted at both ends on gimbal supports.
- each support roller with its roller chocks, is received in one of two cassettes which extend horizontally into the double-sided stand window of the roll stand and is vertically and / or horizontally adjustable in such a way that the cassettes rotate in opposite directions about a common central one vertical axis are pivotable, which is formed by the upper and lower centering pin bearings provided on the stator cross member and on the cassette and that each cassette is supported vertically against the rolling frame in the area of the stator window by means of pendulum supports mounted at both ends on gimbal supports.
- the pivoting of the cassettes with the respective rollers or pairs of rollers accommodated therein can be carried out according to an embodiment of the invention by means of essentially horizontally acting power drives which act on the one hand on the roller stand and on the other hand on the respective cassette.
- Mechanical synchronization means prevent the cassette from tilting in the roller stand.
- the cassettes can advantageously be clamped between hydraulic cylinders arranged on both sides, so that there is no play
- the cassettes can be hydraulically balanced against the upper and lower pendulum supports.
- the lower balancing serves at the same time to raise the system for changing the rollers and to enable the step wedges to be moved to adjust the pass-line.
- the hydraulic cylinders for adjusting the pair of rollers vertically adjustably mounted in the upper or lower cassette are installed together with the associated servo valves as well as the balancing and bending cylinders for the rollers within the cassette.
- This ensures that the rolling forces are always introduced centrally and, on the other hand, the installation and removal of the rolls is significantly simplified.
- the cassette solution according to the invention allows the work rolls to be moved in the axial direction as well as a positive and negative work roll bending.
- each work roll is displaceable in the axial direction via a two-armed lever system, the pivot point of which is arranged on the cassette, one lever arm of which is connected to a power drive supported on the cassette and the other Lever arm is non-positively or positively connected to the chock of the work roll.
- connection of the lever arm to the chock takes place via rollers which are arranged at the end of the lever and are supported on the chock.
- lever arms can be pivoted away in the area of the chocks transversely to the direction of displacement of the work rolls in order to enable the work rolls to be removed.
- FIG. 1 shows the side view of a four-high mill stand according to the invention
- FIG. 2 shows a view of the rolling stand according to FIG. 1 rotated by 90 °.
- 1 denotes the stand of a four-high roll stand, the work rolls 2a, 2b and backup rolls 3a, 3b of which are in pairs 2a, 3a and 2b, 3b in an upper cassette 4a and a lower cassette 4b, respectively, being vertically displaceable led, arranged.
- the work rolls 2a, 2b can also be displaced axially, ie transversely to the plane of the drawing, by means of the double-sided levers 5.
- the cassettes 4a, 4b extend, partially including the roller pairs, transversely to the roller plane from one side of the stand 1 to the other and extend into the stand window 6 provided on both sides of the stand 1. A distance is left between the cheek 6a of each stand window 6 and the cassettes 4a, 4b, which enables the cassettes 4a, 4b to be adjusted laterally.
- Stand crosshead 1a, 1 b of the stand 1, recesses 7 are provided, in which the pendulum supports 8 extend approximately vertically.
- the pendulum supports are gimbaled at their ends.
- spherical support pairings 9 are provided, which enable the pendulum supports 8 to be tilted even under rolling load.
- a vertically extending pin 10 is provided, which engages in the pin bearing 11, which on the upper Cross-beam of the roll stand is attached.
- An identical pin 10 is attached to the lower cassette 4b, directed vertically downward, which engages in the pin bearing 11 on the lower crossbeams 1c of the roll stand 1 or on the base plate.
- the two pins 10 are arranged in alignment in a common vertical axis and form the pivot axis S for the cassettes 4a, 4b when the cassettes are adjusted in opposite directions.
- the upper and lower pendulum supports 8 are by means of the balancing cylinder 12 acting on the cassettes 4a, 4b between the stator crosshead 1b and the
- Waiz accuracy is further improved.
- Each work roll 2a, 2b can be moved in the axial direction via a two-armed lever system 5, the pivot point 19 of which is arranged on the respective cassette 4a or 4b, the one lever arm at 18a of which is connected to a power drive 20 supported on the cassette 4a or 4b, and the latter another lever arm at 18b is non-positively or positively connected to the chock of the work roll.
- the connection of the lever arm 18b to the chock 21 takes place via rollers 22, which are arranged at the end of the lever 5 in a rotatably mounted manner and are supported on the respective chock 21.
- each lever arm can be swung out transversely to the chock 21 in the area of an articulated joint 24 in order to move the roller 22 out of the area of the chock.
- a hydraulic cylinder 25 is arranged between the lever arms of the lever system 5 arranged on both sides of the chocks.
