Description
ROLLER DEVICE WITH ADJUSTER DEVICE
S P E C I F I C A T I O N
Technical Area The invention pertains to a rolling device with an adjusting device, especially for adjusting the horizontal offset of a roll of the rolling device, especially according to the introductory clause of Claim 1.
Prior Art Rolling devices or rolling stands are well known according to the prior art. Rolling stands are known in which a work roll is shifted horizontally relative to the adjacent back-up rolls to provide horizontal stabilization. This is necessary especially when the same rolling device is to be used for different reduction programs. Known adjusting devices include gear adjusting elements, hydraulic cylinders, and wedge adjusters. Adjusting devices with wedges are known from, for example, DE 17 770 54 A. EP 0 154 896 B1 discloses both hydraulic cylinders and mechanical adjusting gears.
In the case of the mechanical adjusting devices, it is a disadvantage that the devices lose their set position; that is, the set position shifts during the course of the rolling operations. This disadvantage is encountered in the case of adjusting devices with built-in gearing, for example, because no self-locking of the gears or braking is provided, and thus the position is able shift under load. This means that the sensor or pickup used for monitoring also loses its absolute position.
In the case of rolling devices with gearing, furthermore, relatively large spaces are provided in the rolling stands, so that the devices are therefore very large and heavy.
There is also the effect that the position cannot be set with sufficient reproducibility. The amount of space required is also relatively large. This is the case with adjusting devices with wedges. It can also occur that the adjusting wedges are pulled out too far when the machine is started up and thus contact with the area to be shifted is lost. The sensor loses its position as a result here, too, and accurate position control is no longer possible. The wedges also typically project out by a considerable amount from the rolling stand area on both the drive side and the operating side. This is unfavorable in turn for the roll change equipment and requires a large amount of casing. This, too, is associated with a large amount of work and is therefore disadvantageous.
Description of the Invention, the Goal, the Solution, and the Advantages The goal of the present invention is to create a rolling device by means of which the disadvantages of the prior art can be reduced if not eliminated entirely.
According to the invention, the goal is achieved by means of a rolling device, especially with a stand with support posts, wherein at least one roll of the rolling stand is arranged in the area between the support posts, and at least one adjusting device for adjusting the roll is provided, wherein the at least one adjusting device is arranged between the roll and the support post and comprises a pressure-medium adjusting element.
It is advantageous for two opposing adjusting devices to be present at each end of the roll.
It is especially advantageous for the pressure-medium adjusting element to comprise a hydraulic actuator with a piston-cylinder unit. The pressure-medium adjusting element, however, can also be operated pneumatically or by the use of some other pressure medium.
It is advantageous for the piston-cylinder unit to comprise a piston which moves in a direction perpendicular to the axis of the roll or which is aligned in such a way that its adjusting movement takes place perpendicular to the axis of the roll.
It is also advantageous for the adjusting device to comprise two pressure spaces for exerting pressure on the piston, wherein one of these spaces is located on one side of the piston, the other space on the opposite side. Thus the position of the piston can be reliably adjusted or controlled.

It is also advantageous for the position of the piston to be detectable by a sensor. It is effective for the sensor to be integrated into the housing of the adjusting device or to be connected to it, especially mounted on the outside surface thereof. It is advantageous here that the position of the sensor cannot be lost, because the sensor can be connected directly to the movable element of the piston-cylinder unit or to the elements which move relative to each other.
Advantageous elaborations are described in the subclaims.
Brief Description of the Figures In the following, the invention is explained in greater detail on the basis of an exemplary embodiment, illustrated in the figures:
-- Figure 1 shows a schematic diagram of a rolling device with a work roll with adjusting devices;
-- Figure 2 shows a schematic diagram of an adjusting device; and -- Figure 3 shows a schematic diagram of an adjusting device.
Preferred Embodiment of the Invention Figure 1 shows schematically a view of a rolling device 1 with a stand 2, such as a rolling stand, with four support posts 2a, 2b, 2c, 2d, and with a work roll 3, which is supported in roller bearings or work roll bending blocks 4 and arranged in the area between the support posts 2a, 2b, 2c, 2d. Between the support posts 2a, 2b, 2c, 2d of the stand 2 and the roller bearings or work roll bending blocks or slide blocks 4, adjusting devices 5 are provided to shift the roll or the work roll 3 in the direction 6 perpendicular to the axial direction 7 of the roll. For this purpose, the roll 3 is supported on a chock 8.
The adjusting devices 5 are therefore used for the horizontal adjustment of the roll 3 in a direction perpendicular to the axis of the roll 3.
As can be seen in Figure 1, the adjusting devices 5 are arranged in such a way that they produce an adjusting movement in the direction of the arrow 6, perpendicular to the axis 7.
According to an exemplary embodiment of the invention, the adjusting device 10 of a rolling device is formed by a pressure-medium actuator such as a hydraulic actuator 11, as shown in Figure 2.
The hydraulic actuator 11 is arranged between the roll 13 and the support post 12 in such a way that a pressure space 25 is formed between the component 23 and the component 18. A
pressure medium can be introduced into the pressure space 25 or put under pressure there, so that force is exerted on the two components 23 and 18 in opposite directions. The two components can therefore be pushed away from each other, or they can be moved toward each other.
A piston 14, furthermore, is installed in a cylinder space 15, 16, so that two pressure medium-actuated cylinders or spaces 15, 16 are formed, wherein the spaces 15 and 16 are on opposite sides of the piston 14, so that increasing the pressure in the space 15 has the effect of moving the piston 14 toward the roll and increasing the pressure in the space 16 has the effect of moving the piston 14 away from the roll. The piston-cylinder unit 14, 15, 16 creates a position-holding or position-setting device, which is designed as a retaining cylinder and which also serves to retract the elements 20, 21, and 23.
The spatial area 15, 16 is formed in a housing 17, which is connected to the support post 12. It is advantageous to design the housing 17 in two parts, so that it consists of the assembly of the two housing components 18, 19. The body of the piston is held in the housing 17, and its piston rod projects through an opening in the housing component 18, so that the projecting end of the rod can be connected to the roller bearing 20. It is advantageous to provide an intermediate element 21 here, which allows guidance in the direction perpendicular to the direction of movement of the adjusting device and perpendicular to the axis of the roll.
The cylinder of the spatial area 25 is also formed by the elements 23 and 18 and is accommodated in a recess in the block 17.
In the housing 17, a sensor 22, which directly or indirectly detects the position of the element 23 actuated by the cylinder 25 is also provided in the housing 17, next to the arrangement of the cylinder 14 and the two cylinder spaces 15, 16. The sensor 22 comprises a pin 24, which is supported on the element 21 or the element 23 connected thereto.
The particular advantage of this embodiment is the accuracy with which the position can be controlled by the pressure-actuatable spaces or cylinders 25 and/or 15, 16, so that the position of the element 23 and/or of the piston 14 and thus also the position of the roll 13 can be set precisely at any time.
The design according to Figure 2 is also especially compact in design, because the hydraulic unit with the piston-cylinder unit 25 acts directly on the roll 3.
According to another exemplary embodiment of the invention, the adjusting device 30 is formed by a pressure-medium actuator such as a hydraulic actuator 31, which acts on the roll 3 by way of a lever arrangement 32, as shown in Figure 3. The hydraulic actuator 31 is arranged between the roll 3 and the support post 33 in such a way that the piston 34 is held in a cylinder space 35, 36 and forms two pressure medium-actuatable spaces 35, 36, wherein the spaces 35 and 36 are arranged on opposite sides of the piston 34, so that increasing the pressure in the space 35 moves or exerts force on the piston 34 to the right, and increasing the pressure in the space 36 moves the piston 34 or exerts pressure on it toward the left.
The spatial area 35, 36 is formed in a housing 37, which is connected to a housing 38, which holds the lever arrangement 32 and is attached in turn to the support post 33. It is advantageous to design the housing 37 in two parts, that is, for the housing to be assembled from the two housing components 39, 40, wherein the component 39 is designed in the form of a cup, and the component 40 is designed in the form of a flange. The flange 40 comprises an opening, through which the piston rod 41 projects, so that it can shift the roll 3 by acting on the lever arrangement 32. A seal 42 is also provided in the area of the opening in the flange 40.
The piston rod 41 is connected to an axially movable rod 43, which is designed with a joint 44, to which a lever arm 45 is connected in articulatable fashion. The lever arm is connected in articulated fashion to the element 21 by another joint 46. This part 21 is connected in turn to the roller bearing 20, so that a displacement of the element 21 is transmitted directly to the roll 3.
When the piston 34 is shifted as the result of an increase in pressure in the pressure space 35 or 36, the piston rod 41 is shifted and moved to a predefinable position. As a result, the rod, such as a pushrod, is shifted axially, as is the joint 44 also. Because the roller bearing 20 is designed to be essentially immovable in the direction of the axis of the roll, the displacement of the joint 44 has the effect of changing the position of the lever arm 45 relative to the roll, i.e., of changing the angle of the lever arm to the axis of the roll or to a line perpendicular to that axis, and thus the distance between the stand 33 and the roll is defined and adjusted. So that the roller bearings are essentially immovable in the direction parallel to the axis of the roll, they are locked in place by the guides 47, which allow movement only in the direction perpendicular to the axis of the roll.
As a result of the arrangement of the piston and the pushrod parallel to the roll axis, a very compact design of the adjusting device is obtained.
So that the position of the piston can be detected for the purpose of controlling the position of the roll in either an open-loop or closed-loop manner, a sensor 48 is provided, which uses a feeler 49 to detect the position of the piston. For this purpose, an opening, through which the feeler 49 of the sensor 48 can project and thus engage in an opening or bore in the piston, is created in the head of the housing 39.

It is also advantageous in another exemplary embodiment for the piston-cylinder unit to comprise a piston which moves in a direction parallel to the axis of the roll or which is aligned in such a way that that its adjusting movement occurs parallel to the axis of the roll.
It is advantageous in this case for the adjusting device to comprise two pressure spaces for exerting pressure on the piston, wherein the spaces are located on opposite sides of the piston.
It is also effective for a piston rod connected to the piston to act on the roll directly or indirectly in the adjusting direction of the roll by way of a lever arrangement, where the piston is adjusted in a direction parallel to the axis of the roll and the at least one lever of the lever arrangement has the effect of adjusting the roll in the direction perpendicular to the axis of the roll.
It is also advantageous for the position of the piston to be detectable by a sensor. It is effective for the sensor to be integrated into the housing of the adjusting device or to be connected to it, especially mounted on the outside surface thereof. It is advantageous here that the position of the sensor cannot be lost, because the sensor can be connected directly to the movable element of the piston-cylinder unit or to the elements which move relative to each other.
Advantageous elaborations are described in the subclaims.
Brief Description of the Figures In the following, the invention is explained in greater detail on the basis of an exemplary embodiment, illustrated in the figures:
-- Figure 1 shows a schematic diagram of a rolling device with a work roll with adjusting devices;
-- Figure 2 shows a schematic diagram of an adjusting device; and -- Figure 3 shows a schematic diagram of an adjusting device.
Preferred Embodiment of the Invention Figure 1 shows schematically a view of a rolling device 1 with a stand 2, such as a rolling stand, with four support posts 2a, 2b, 2c, 2d, and with a work roll 3, which is supported in roller bearings or work roll bending blocks 4 and arranged in the area between the support posts 2a, 2b, 2c, 2d. Between the support posts 2a, 2b, 2c, 2d of the stand 2 and the roller bearings or work roll bending blocks or slide blocks 4, adjusting devices 5 are provided to shift the roll or the work roll 3 in the direction 6 perpendicular to the axial direction 7 of the roll. For this purpose, the roll 3 is supported on a chock 8.
The adjusting devices 5 are therefore used for the horizontal adjustment of the roll 3 in a direction perpendicular to the axis of the roll 3.
As can be seen in Figure 1, the adjusting devices 5 are arranged in such a way that they produce an adjusting movement in the direction of the arrow 6, perpendicular to the axis 7.
According to an exemplary embodiment of the invention, the adjusting device 10 of a rolling device is formed by a pressure-medium actuator such as a hydraulic actuator 11, as shown in Figure 2.
The hydraulic actuator 11 is arranged between the roll 13 and the support post 12 in such a way that a pressure space 25 is formed between the component 23 and the component 18. A
pressure medium can be introduced into the pressure space 25 or put under pressure there, so that force is exerted on the two components 23 and 18 in opposite directions. The two components can therefore be pushed away from each other, or they can be moved toward each other.
A piston 14, furthermore, is installed in a cylinder space 15, 16, so that two pressure medium-actuated cylinders or spaces 15, 16 are formed, wherein the spaces 15 and 16 are on opposite sides of the piston 14, so that increasing the pressure in the space 15 has the effect of moving the piston 14 toward the roll and increasing the pressure in the space 16 has the effect of moving the piston 14 away from the roll. The piston-cylinder unit 14, 15, 16 creates a position-holding or position-setting device, which is designed as a retaining cylinder and which also serves to retract the elements 20, 21, and 23.
The spatial area 15, 16 is formed in a housing 17, which is connected to the support post 12. It is advantageous to design the housing 17 in two parts, so that it consists of the assembly of the two housing components 18, 19. The body of the piston is held in the housing 17, and its piston rod projects through an opening in the housing component 18, so that the projecting end of the rod can be connected to the roller bearing 20. It is advantageous to provide an intermediate element 21 here, which allows guidance in the direction perpendicular to the direction of movement of the adjusting device and perpendicular to the axis of the roll.
The cylinder of the spatial area 25 is also formed by the elements 23 and 18 and is accommodated in a recess in the block 17.
In the housing 17, a sensor 22, which directly or indirectly detects the position of the element 23 actuated by the cylinder 25 is also provided in the housing 17, next to the arrangement of the cylinder 14 and the two cylinder spaces 15, 16. The sensor 22 comprises a pin 24, which is supported on the element 21 or the element 23 connected thereto.
The particular advantage of this embodiment is the accuracy with which the position can be controlled by the pressure-actuatable spaces or cylinders 25 and/or 15, 16, so that the position of the element 23 and/or of the piston 14 and thus also the position of the roll 13 can be set precisely at any time.
The design according to Figure 2 is also especially compact in design, because the hydraulic unit with the piston-cylinder unit 25 acts directly on the roll 3.
According to another exemplary embodiment of the invention, the adjusting device 30 is formed by a pressure-medium actuator such as a hydraulic actuator 31, which acts on the roll 3 by way of a lever arrangement 32, as shown in Figure 3. The hydraulic actuator 31 is arranged between the roll 3 and the support post 33 in such a way that the piston 34 is held in a cylinder space 35, 36 and forms two pressure medium-actuatable spaces 35, 36, wherein the spaces 35 and 36 are arranged on opposite sides of the piston 34, so that increasing the pressure in the space 35 moves or exerts force on the piston 34 to the right, and increasing the pressure in the space 36 moves the piston 34 or exerts pressure on it toward the left.
The spatial area 35, 36 is formed in a housing 37, which is connected to a housing 38, which holds the lever arrangement 32 and is attached in turn to the support post 33. It is advantageous to design the housing 37 in two parts, that is, for the housing to be assembled from the two housing components 39, 40, wherein the component 39 is designed in the form of a cup, and the component 40 is designed in the form of a flange. The flange 40 comprises an opening, through which the piston rod 41 projects, so that it can shift the roll 3 by acting on the lever arrangement 32. A seal 42 is also provided in the area of the opening in the flange 40.
The piston rod 41 is connected to an axially movable rod 43, which is designed with a joint 44, to which a lever arm 45 is connected in articulatable fashion. The lever arm is connected in articulated fashion to the element 21 by another joint 46. This part 21 is connected in turn to the roller bearing 20, so that a displacement of the element 21 is transmitted directly to the roll 3.
When the piston 34 is shifted as the result of an increase in pressure in the pressure space 35 or 36, the piston rod 41 is shifted and moved to a predefinable position. As a result, the rod, such as a pushrod, is shifted axially, as is the joint 44 also. Because the roller bearing 20 is designed to be essentially immovable in the direction of the axis of the roll, the displacement of the joint 44 has the effect of changing the position of the lever arm 45 relative to the roll, i.e., of changing the angle of the lever arm to the axis of the roll or to a line perpendicular to that axis, and thus the distance between the stand 33 and the roll is defined and adjusted. So that the roller bearings are essentially immovable in the direction parallel to the axis of the roll, they are locked in place by the guides 47, which allow movement only in the direction perpendicular to the axis of the roll.
As a result of the arrangement of the piston and the pushrod parallel to the roll axis, a very compact design of the adjusting device is obtained.
So that the position of the piston can be detected for the purpose of controlling the position of the roll in either an open-loop or closed-loop manner, a sensor 48 is provided, which uses a feeler 49 to detect the position of the piston. For this purpose, an opening, through which the feeler 49 of the sensor 48 can project and thus engage in an opening or bore in the piston, is created in the head of the housing 39.
