Description of the invention (3) The first type is a bending cylinder 13 that gives bending force to the work roll 3 or adjusts the position of the work roll 3. The first pressing device moves the upper and lower parts through the bearing box 7 for work rolls. The desired force is applied to both ends of the work roll 3. The second kind of second pressing device for shock absorption, that is, the shock cylinder. The second pressing device is the work roller through the work bearing box 7. 3. A horizontal force can be applied. That is, a desired force can be applied to the work roll 3 in a direction orthogonal to the roller axis direction. Here, the bending cylinder 1 of the first pressing device is installed on the machine. The frame 2 is fixedly or slidably arranged between the block 12 of the frame 2 and the bearing box 7 for work rolls. In order to improve the accuracy of the shape or thickness of the finished plate, a large-sized and high-output hydraulic cylinder is ideal.

Description of the invention (4) (Please read the precautions on the back before filling this page) The distance will be longer, and the bending moment will be larger. In this way, the roll bearing box member receiving the output of the bending cylinder 13 is increased in size, and it is necessary to be a high-strength person to increase the size of the rolling mill. Table 4 is a partial enlarged view showing FIG. 1. The bending moment μ is expressed by M = F · L (F: roll cylinder output, L: distance). In order to reduce the bending moment, the distance L must be shortened, or the output F must be reduced. As described above, since the output F of the roll cylinder 13 must be increased, in order to reduce the bending moment M, it is desirable to shorten the distance L between the roll cylinder 13 and the fixed end of the bearing box member receiving the output. --Line. When the shock absorber is used, the roller bearing box is pushed in the horizontal direction, so friction resistance between the roller milk bearing box and the frame 2 or the block 12 occurs during rolling. Since this frictional resistance acts in the opposite direction to the rolling load, it may become a noise of a load cell that measures the rolling load, which may have an adverse effect on the shape or thickness accuracy of the finished plate. The friction resistance Q is represented by Q = K · // (K: suspension cylinder output,: friction coefficient). As the output of the suspension cylinder becomes larger and larger, the noise given to the load cell becomes larger.

There is a gap G between the work roll bearing box 7 and the frame 2 or the block 12 to form a structure in which the work roll bearing box 7 is pulled out of the rolling mill in two parts with the work roll 3 when the work roll 3 is exchanged.

With such a configuration, the overall equipment system does not become large, and the roll cylinder 13 and the shock-absorbing cylinder 15 can be made into large cylinders, respectively. That is, it does not impair the shape controllability of the rolled material 1 and becomes a device that stabilizes the position of the work roll bearing box 7 in the horizontal direction. That is, by providing the first pressing device and the second pressing device with the rollers offset in the axial direction, it is possible to obtain vibration isolation of the roller bearing box of the rolling mill without increasing the size of the equipment. A plurality of (for example, two) first pressing devices for imparting the balance force or bending force in the vertical direction to the roll via a roller bearing box are provided, and the first axial pressing device is located between the two first pressing devices in the rolling axis. It is set in the horizontal plane to give the pressing force in the direction orthogonal to the rolling axis to the second pressing device of the roller bearing box, so that the equipment will not be enlarged and the output capacity of the balance force or bending force will not be reduced. The shock absorption of the roller bearing box of the rolling mill is obtained. Because the first pressing device is arranged on both sides of the second pressing device in the direction of the roll axis, the equipment will not be enlarged, and the output capacity of the balance force or bending force will not be reduced.

In addition, the roller bearing box rotatably supports the roller bearing box that rolls the rolled material 1, and the balancing force or bending force in the vertical direction is given to the balancing force or bending from a plurality of positions through the roller bearing box in the roll axis direction. The force is applied to the roller bearing box from a portion between a plurality of portions to which the balance force or bending force is given in a horizontal plane to the roller bearing box to be rolled, thereby forming a stable roll.

Description of the invention (7) It is located at a position deviating from the axial position of the roller of the first pressing device for the balance or bending force to the roller. By setting it in the horizontal plane, it will be orthogonal to the roller axis. The pushing force in the direction is given to the second pushing device of the roller bearing box, which can be easily reconstructed without impairing the ability of balance force or bending force, and it is possible to modify the shock-absorbing mechanism. Furthermore, in the case of a four-stage rolling mill or a six-stage rolling mill, for example, since a shock cylinder for a work roll bearing box is provided, even if the position of the work roll is stabilized due to the position of the other rolls supporting the work roll 3, the work roll is not stabilized In some cases, a more stable rolling can be performed by combining a suspension cylinder for a work roll bearing box with a stable suspension cylinder that positions the roll supporting the work roll 3 to be stable. (Example 2) Hereinafter, a case where the work roll 3 is eccentric will be described. When biting into the rolling material 1, the work roll 3 generates an excessive horizontal force on the input side, and the support roll system supporting the work roll 3 receives a reaction force and generates a horizontal force on the output side. This support roll is a reinforcing roll 5 in a four-stage rolling mill and an intermediate roll 4 in a six-stage rolling mill. During frequent rolling, the eccentric horizontal component force generation direction of the work roll 3 is shown in FIG. 5. The horizontal force system of the work roll 3 occurs when the work roll 3 becomes eccentric on the entry side of the support roller 3. It becomes the inbound direction. The horizontal force occurring in the intermediate roll 4 supporting the rolls of the work roll 3 is oriented in the outgoing direction. _ · In this way, because the direction of the horizontal force of each roll that occurs during rolling is different depending on the rolling state or eccentricity, the size of this paper is pushed by the shock cylinder to apply Chinese National Standard (CNS) A4 Specifications (210 X 297 mm) 10- (Please read the notes on the back before filling out this page) # _ 线 · 497999 A7 ____ B7 Printed by the Intellectual Property Office of the Ministry of Economic Affairs and Consumer Cooperatives V. Invention Description (8) Roller bearings The direction of the box becomes important. For example, even if a shock absorber cylinder is provided on the work roll 3 and the work roll bearing box 7 is pushed in the horizontal direction, the roll supporting the work roll 3 is mechanically restrained in the horizontal direction, so the position in the horizontal direction becomes unstable. . There is also a problem that the direction and magnitude of the partial force of the eccentric horizontal component of the work roll 3 via the roll supporting the work roll 3 become unstable. As shown in Fig. 2, the rolling load is given to the reinforced roller bearing box 8 by pressing down the jack 9 and the work roll 3 is added to the work roll 3 via the reinforced roller 5 to roll the rolling material 1 with milk. The rolling load was measured with a load cell 10 under pressure. The axis 0 W of the work roll 3 is only eccentric δ from the axis O B of the reinforcing roll 5 toward the entrance side of the rolling material 1. In the structure of the roll shown in FIG. 2, since the eccentric horizontal component force acting on the work roll 3 is the direction of the incoming side of the rolling material 1, the shock absorber cylinder 15 for the milk roll is provided on the exit side. The block 1.2b, and The work roll bearing box 7 is pushed toward the inlet block 1 2 a. Since the eccentric horizontal component force acting on the reinforcing roller 5 is subjected to the reaction force of the eccentric horizontal component force of the work roll 3 and becomes the direction of the outgoing side of the rolling material 1, a suspension cylinder 17 for the reinforcing roller is provided in the bearing box of the reinforcing roller. 8 in the direction of the entry side, and push the reinforcing roller bearing box 8 in the direction of the exit side of the frame 2. Although the shock-absorbing cylinder 17 for the reinforcing roller is provided in the reinforcing-roller bearing box 8, the shock-absorbing cylinder 17 for the reinforcing roller is provided in the entrance side of the frame 2 and the bearing box 8 for the reinforcing roller is pushed toward the frame 2. The exit direction is also acceptable. By providing a 辊 · vibration cylinder 15 for work rolls and a suspension cylinder 17 for reinforcement rolls, the eccentric horizontal component force plus the output of the suspension cylinder acts on each roller bearing box during rolling, which can suppress the rolling The roller bearing box moves horizontally.

Invention Note (9) (Please read the precautions on the back before filling in this page) For example, in the second figure, the work roll 2 is pushed by the shock cylinder 15 by the work roll, and the block 1 2 a and the output side The side block 1 2 b may sandwich the work roll bearing box 7 to suppress the horizontal movement of the work roll bearing box 7. Fig. 5 shows an example in which the suspension cylinder of the present invention is installed in a six-stage rolling mill. In the figure, the axial center of the work roll 3 is only eccentric 5 with respect to the axial centers of the intermediate roll 4 and the reinforcing roll 5 in the direction in which the rolling material 1 enters. When the work roll 3 is eccentric toward the entrance side and a light milk load P is imparted, the work roll 3 has an eccentric horizontal component force HW acting in the entrance side direction, and the intermediate roll 4 acts as a reaction force of the HW, having an eccentric horizontal component force I acts on the exit-side direction opposite to HW. In the reinforcing roller 5, as a reaction force of 在 I, there is an eccentric horizontal component force ΗB which acts on the inward side direction opposite to ΗI. -Line · Printed and installed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, the shock cylinders 15 for work rolls, the shock cylinders 16 for intermediate rolls, and the reinforcement rollers 17 become eccentrics that push each roller bearing box toward each roller. The horizontal component force generation direction can suppress the horizontal movement of each roller bearing box during rolling. In FIG. 5, since the axial centers of the intermediate roller 4 and the reinforcing roller 5 are not eccentric, the eccentric horizontal component force acting on the reinforcing roller 5 is extremely small. Therefore, at this time, the intermediate roller 4 and the reinforcing roller 5 are pushed. It is also possible to go out in the same direction. In other words, it is also possible to push the reinforcing roller bearing box toward the outgoing side by using the suspension cylinder 17 for the reinforcing roller. Furthermore, in a rolling mill provided with a first roll bearing box of a roll and a second roll bearing box of a support roll supporting the roll, a pressing force in a direction orthogonal to the roll axis in a horizontal plane is given to the first A pressing device of a roller bearing box is provided at the exit side of the rolling mill, and a pressing device of a second roller bearing box is provided at the entrance side of the rolling mill by applying a pressing force in a direction orthogonal to the roller axis in the horizontal plane to the incoming side of the rolling mill.

Description of the invention (1) The stability of the horizontal direction of the rolls can be sought. This is particularly effective when the roll is eccentric. In addition, since the rolls and directions in which horizontal forces occur are different depending on the type of the rolling mill, it is not necessary to install the shock cylinder of the present invention on all rolls, for example, only the shock cylinder 15 for work rolls is provided, or It is also possible to provide a combination of the shock cylinder 15 for work rolls and the shock cylinder 17 for reinforcement rolls. Fig. 6 shows as an example the resistance Q of the shock cylinder when the shock cylinder 15 for work rolls is provided. An outline of the rolling load P. In this figure, in order to show the relationship between the rolling load P and the resistance Q of the suspension cylinder, other forces are omitted. Since the work roll 3 is eccentric to the entrance roll with respect to the intermediate roll 4 and the reinforcing roll 5, the work roll suspension cylinder 15 is provided on the exit side, and the work roll bearing box is pushed toward the entrance side. When the roll bearing box is pushed in the direction of the input side by using the work roll suspension cylinder 15 to output K, the roll bearing box receives a reaction force K from the frame 2 or the block 12 on the input side. The rolling load P is given under the condition that the output of the work roll suspension cylinder 15 is K, then the contact surface between the work roll suspension cylinder 15 and the work roll bearing box and the roll bearing box and the incoming machine The contact surface of the frame 2 or the block 12 will cause friction resistance Q in the direction opposite to the rolling load P. The friction resistance Q is based on Q = K · // (//: friction coefficient), and the resistance to the rolling load P becomes larger according to the output K of the work roll shock absorber 15. As described above, if the frictional resistance Q becomes large, the noise of the load cell for measuring the rolling load P becomes larger, and there is a problem that the accuracy of the finished plate shape or plate thickness deteriorates. Therefore, the horizontal position of the work roll 3 is relatively small. Stability statement (please read the notes on the back before filling this page) Secret · Order-· Thread.

Description of the invention (11) During stable rolling, reducing the output of the shock cylinder 15 for work rolls 俾 The reduction is ideal for the pressure sensor noise reduction. The direction in which the bearing box is pushed by the work roll becomes the same direction as the action of the eccentric horizontal component force received by the roll. Because the eccentric horizontal component force plus the force output by the shock cylinder acts as a horizontal force in the roller bearing box, More stable rolling is possible. Since the horizontal force generated by the eccentric horizontal component force acting on the work roll 3 and the roll supporting the work roll 3 becomes the opposite direction by action or reaction, the pressing direction of the roller bearing box generated by the shock cylinder is also Become the opposite. Occurs when the horizontal force of the roll is in the opposite direction to the eccentric horizontal component force when the plate is bitten, because the piston sliding shaft of the roll balancing cylinder or the bending cylinder 13 is deviated from the piston sliding shaft of the suspension cylinder. The high-output shock cylinder can be set to push the bearing box of the shock cylinder in the same direction as the eccentric horizontal component force direction, and a horizontal force greater than the horizontal force occurring when biting can be applied to the roller. The bearing box can stabilize the horizontal position of the roll. In addition, the roll is eccentric in the horizontal plane in a direction orthogonal to the roll axis. The second pressing device pushes the roll bearing box in the direction of the eccentric horizontal component force of the roll. The thrust generated by the cylinder output is extremely efficient and can be used for shock absorption. In addition, by changing the output of the suspension cylinder according to the rolling condition, the noise of the load cell 1 · 0 during stable rolling can be minimized, and the rolled material 1 with good plate shape and thickness accuracy can be produced. The trouble of meandering or drawing of the rolled material 1 during rolling can also be reduced.

Description of the invention (12) When the roller bearing box is moved in a direction where the horizontal force generated when biting is large and is opposite to the action direction of the eccentric horizontal component force, the eccentric horizontal component force and the output of the shock cylinder can also be used to roll the bearing after the bite The position of the box returns to the action direction of the eccentric horizontal component force and becomes stable. However, if a high-output shock cylinder is also used during stable rolling, as described above, there is a problem that the noise of the load cell for reduction becomes large. Since the roll position is stable when the roll is stabilized, it is avoided. The output of the shock cylinder is lower and better. Excessive horizontal forces such as when the plate is biting act on the rolls and use the shock absorber with a high output, and when the horizontal position of the rolls when the roll is stable is more stable, it can be solved by using the shock absorber with a low output. As such a method, there is a method in which a circuit for supplying oil pressure to the suspension cylinder is switched between high and low pressure. In the stable rolling, the position of the roller is fully settled by eccentric horizontal molecules. The shock absorber is used only when a large horizontal force such as a plate bite is applied to the roller, and it is not used in the stable rolling. Methods are also available.

The hydraulic circuit that supplies oil pressure to the original suspension cylinder is set in a different system from the supply circuit of the red cylinder 13. This can be controlled independently of each other. The original circuit is equipped with a solenoid valve 19 for the opening and closing device for setting and resetting the suspension cylinder, a solenoid valve 20 for a switching device for switching between high pressure and low pressure, and a pressure reducing valve 21 for pressure setting.

In the following, the low-pressure and high-pressure settings for use of the suspension cylinder 15 will be described. Fig. 8 shows a state in which the suspension cylinder is set at a low pressure. The low pressure setting system is to first set the solenoid valve 20 to a low pressure, and set the safety valve 2 2 a in the circuit of part C to a low pressure PL, and set the oil pressure in the circuit of part C to PL. In this way, the set pressure of the safety valve 2 2 b, which changes the safety pressure by the pressure of the part C, also becomes the low pressure PL, and the oil pressure supplied to the shock cylinder 15 becomes the low pressure PL, and the shock cylinder system becomes the low pressure. Its output. When the solenoid valve 20 is set to the opposite high pressure in this figure, since the safety valve 2 2 a is not passed, the hydraulic pressure in the circuit of the part C becomes the high pressure P Η. In this way, since the set pressure of the safety valve 2 2 b also becomes a high-pressure PH, the oil pressure supplied to the shock-absorbing cylinder 15 becomes a high-pressure PH, and the output when the shock-absorbing cylinder system becomes a high pressure. With this configuration, the output of the suspension cylinder 15 can be changed. As described above, since the second pressing device includes at least one of a switching device that changes its thrust and a switching device that reduces its thrust to zero, it is possible to solve the problem of using a high-output suspension cylinder for stable rolling. There is a problem that noise generated by the load cell for reduction becomes large at that time.

In order to maximize the bending force and the reduced bending force, it is desirable to provide each cylinder so that the increased bending force and the reduced bending force become the same output. For example, when two increasing bending machines 1 3 a and one reducing bending machine 1 3 b are set in the block 1 2 b, the warp of the reducing bending machine 1 3 b is regarded as 0 D, and the increasing bending machine 1 is set.
