    A controlled deflection roll possesses a roll shell which is radially movable in at least one plane in relation to a roll support. Position feelers or sensors are arranged at the ends of the roll shell. These position feelers control regulators operatively associated with pressure or support elements located between the roll support and the roll shell, as a function of deviations from a predetermined reference or set position, in a manner such that the roll shell is maintained in the reference or set position. It is possible to influence the pressure or support elements by the position feelers either equally or unequally, and specifically, with decreasing intensity in the presence of increasing distance from the related position feeler.

    This invention relates to rolling production, in particular to structures of mill rolls with adjustable deflection.
    Known roll with adjustable deflection, containing a fixed beam with a bandage mounted on it with a guaranteed clearance, installed with a power of displacement in diametrically perpendicular directions relative to the beam, and movable hydrostatic supports arranged along the beam with pressure regulators „
    The disadvantage of this roll is that it doesn’t seem Vozmokhnichi in it to correct the position of the gangs in the case of its deviation from the given nominal position.
    The aim of the invention is to ensure the possibility of adjusting the position of the band when it deviates from the specified nominal position
    The goal is achieved by the fact that a roller with an adjustable deflection, containing a fixed beam with a gang mounted on it with a guaranteed clearance; ohm mounted for movement in diametrically perpendicular directions relative to the beam and movable hydrostatic supports arranged along the beam with pressure regulators are equipped with radial position gauges relative to the beam mounted on its end portions and connected to the pressure regulators.
    Each position sensor is connected to half of the pressure regulators facing the moving hydrostatic supports, counting from the center of the roll.
    In addition, each position sensor is connected to at least two pressure regulators of the indicated supports, which interact with adjacent ones.
    the end parts of the bandage.
    In addition, each position sensor is additionally connected to the pressure regulators of the said supports, located on the other side of the center.
    rolls so that the pressure regulators of the supports of one half of the roll are connected to the sensor of the shelf installed on the opposite end part of the bandage, and the pressure regulators of the supports
    the second half of the roll, respectively, are connected to another position sensor
    Moreover, mobile hydrostatic bearings are mounted preferably
    in one plane, perpendicular to the rolling axis, and the end portions of the band are provided with guides arranged parallel to the rolling plane. In FIG. 1 depicts the proposed
    roll in a pair with an adjacent monolithic roll, general view; in Fig. 2 - the end part of the roll in Fig ..- 1, a longitudinal section; FIG. 3, the end (supporting part of the roll in FIG. 2, cross section; FIG. 4, the same,
    an embodiment; in fig. 5 is a diagram of the relationship of the position sensors with the pressure regulators; Fig. 6 shows an interconnection diagram of position sensors with half-bed regulators, an embodiment; FIGS. 7 and 8 are diagrams of the operation of the circuits in FIG. 5 and 6.
    The proposed roll consists of a fixed beam 1, on which a bandal 2 is mounted with a guaranteed clearance. In beam 1, there are movable hydrostatic supports 3 to which working fluid is supplied from a high pressure source by pressure regulators k on the end meters of the beam. 1, sensors 5 are installed to determine the radial position of the band 2 relative to the beam. The position sensors 5 are connected by signal wires bis regulators, which through throttle valves (not shown) act on the pressure of the working fluid supplied through pipeline 7, each support 3 moves in a cylindrical bore 8 connected through a supply channel 9 to the corresponding branch of the pipeline 7 Balka 1 is provided with a sleeve 10, onto which, through bearings 11, a supporting band 2 is supported. The cavity between sleeve 10 and the band 2 is sealed by means of a sealing ring 12 and washers 13. On the sleeve 10, guides are made, mutually operating with the guide beam 1, to allow movement of the shroud in the rolling plane.,
    In an embodiment of the invention, said guides may be absent, i.e., the bandage will be able to move in all radial directions, for this the swath must be provided with at least two rows of hydrostatic supports 3, each row being equipped with sensors 5- Reaction forces The supports 3 must act in the planes A-L or BB, however this does not mean that the axes of these supports must be located in the same planes; supports 3 can be located iHu, for example, V-shaped in two rows symmetrically relative to the plane
    L-A, it is necessary that the resultant reaction forces act in the plane A-L or BB,
    The position sensors 5 may be made of electromagnetic or in the form of hydraulic control spools.
    The proposed roller is primarily intended for picking a roller pair with a solid roller C, Depending on the desired nature of the distribution of rolls pressure, as well as adjusting the position of the tire relative to the initial nominal position, which varies depending on the distribution of the rolls pressure along the length of the barrel, the proposed sensor connection 5 position with control iw | pressures of movable supports 3. When rolling, the forces acting on the band 2 are sensed by the supporting elements 3 supported by the hydraulic medium on the beam. The pressure of the hydraulic medium is regulated by regulators, namely in the direction to maintain the specified position specified by the signal given quantities. If, for example, the end parts of the band 2 are to be deflected under the influence of the rolling pressure acting downwards, then by means of the regulators the hydraulic pressure of the medium and thereby the supporting force will increase. If one of the ends or both ends of the shell move upwards, t, e, overcome the reaction force, then the pressure in the respective cylinders of the supports 3 decreases.
    Thus, in the embodiment of FIG. 1 to each sensor, 5 positions are assigned to the controllers C of the roll half facing towards it, i.e. The left position sensor 5 has four adjustments 4 of the left half, the right position sensor four settings 4 of the right half of the roll. The adjustment can be made in such a way that the setpoint values supplied from the position sensors by the individual controller k are equal. However, they may also be different, namely, preferably with a decrease in intensity with distance from the end on which the corresponding position sensor is located.
    In the embodiment of the circuit according to FIG. 5, the position sensors act only on the regulators of the outer supporting elements or groups of supporting elements. Thus, in the form of the embodiment according to FIG. 5, the controllers of the middle bearing elements 3 are not subjected to the action of the position sensors 5. These controls can be affected by their own 1S control lines, depending on the principle of operation of the rolling mill. In the circuit according to FIG. 6 of the eight regulators, seven are connected to the sensors of the 5 position of one side. In this case, only the regulator C, which is attached to the support element furthest from the position sensor, always remains unused. Thus, according to FIG. 7, the reaction force of the supporting elements 3, imparted to the corresponding sensor of the situation, is the same. In other words, the force changes caused by the position sensor in the four supports 3 or the regulators on one side of FIG. 1 and 5 are the same. In FIG. 8 regulators C and through them the hydrostatic supports 3 are subjected to different effects, namely with a decrease in intensity with an increase in the distance from the corresponding 15 IZ / (/ n / 1
    Figure 2 1 of the current position sensor 5. In the embodiment form according to FIG. 8, the dependence is linear, as shown by straight lines. However, it seems that other dependencies are also possible, for example, a smaller overlap or also a non-linear character of the I curves. The position sensor 5 has the purpose of determining the position of the shell relative to its body. For this purpose it can be connected as shown in FIG. 1, directly with the roll body 1 and the roll casing or its sleeve 10. This design is shown in Fig. 1. However, part of the position sensor may also be in connection with a structural part rigidly connected to the beam. For example, according to FIG. 2, the housing of the position sensor 5 is fixed on the frame, while its movable part is connected to the terminal 10.
