Definitions

  • the invention concerns a rolling installation with an adjusting device, especially for adjusting a horizontal displacement of a roll of the rolling installation, especially in accordance with the preamble of claim 1 .
  • Rolling installations or roll stands are sufficiently well known in the prior art.
  • roll stands are known in which a horizontal displacement of a work roll relative to the adjacent backup rolls is undertaken as horizontal stabilization. This is especially necessary if different pass programs are to be run with the rolling installation.
  • well-known adjusting devices include adjusting transmission elements, hydraulic cylinders, and displaceable wedges for making wedge adjustments. Adjusting devices with wedges are disclosed, for example, by DE 17 770 54 A.
  • EP 0 154 896 B1 discloses both hydraulic cylinders and mechanical adjusting transmissions.
  • the objective of the present invention is to create a rolling installation that reduces the disadvantages of the prior art if it cannot completely eliminate them.
  • this objective is achieved by a rolling installation, especially with a stand with housing uprights, wherein at least one roll of the roll stand is arranged in the space between the housing uprights, and at least one adjusting device is provided for adjusting the roll, wherein the one or more adjusting devices are arranged between the roll and the housing upright and comprises a pressure-medium control element. It is advantageous for two opposing adjusting devices to be present at each end of the roll.
  • the pressure-medium control element comprises a hydraulic actuator with a piston/cylinder unit.
  • the pressure-medium control element can also be pneumatic or it can be operated with a different pressure medium.
  • the piston/cylinder unit has a piston whose direction of motion is perpendicular to the roll axis or is aligned in such a way that its adjustment takes place perpendicularly to the roll axis.
  • the adjusting device has two pressure chambers for applying pressure to the piston, such that the two chambers are arranged at opposite ends of the piston. This allows the position of the piston to be reliably adjusted or controlled.
  • a piston rod connected with the piston acts on the roll directly or indirectly in the adjustment direction of the piston.
  • the piston/cylinder unit has a piston whose direction of motion is parallel to the roll axis or is aligned in such a way that its adjustment takes place parallel to the roll axis.
  • the adjusting device has two pressure chambers for applying pressure to the piston, such that the two chambers are arranged at opposite ends of the piston.
  • a piston rod connected with the piston acts on the roll directly or indirectly in the adjustment direction of the piston by means of a lever arrangement, where the piston is adjusted in the direction parallel to the roll axis, and the one or more levers of the lever arrangement bring about the adjustment of the roll perpendicularly to the roll axis.
  • the position of the piston can be detected by a sensor.
  • the sensor is integrated in the housing of the adjusting device or is connected with it, especially by being externally mounted on it. This provides the advantage that the position of the sensor cannot be lost, because the sensor can be directly connected with the displaceable element of the piston/cylinder unit or with the elements that can be displaced relative to each other.
  • FIG. 1 is a schematic representation of a rolling installation with a work roll with adjusting devices.
  • FIG. 2 is a schematic representation of an adjusting device.
  • FIG. 3 is a schematic representation of an adjusting device.
  • FIG. 1 is a schematic view of a rolling installation 1 with a stand 2 , such as a roll stand, with four mill housing uprights 2 a, 2 b, 2 c, 2 d, and with a work roll 3 , which is installed in the region between the housing uprights 2 a, 2 b , 2 c, 2 d and supported in roll bearings 4 .
  • Adjusting devices 5 are provided between the housing uprights 2 a, 2 b, 2 c, 2 d of the stand 2 and the roll bearings or work roll bending blocks or adjustable blocks 4 for displacing the roll or the work roll 3 in the direction 6 perpendicularly to the axial direction 7 of the roll.
  • the roll 3 is supported on a chock 8 .
  • the adjusting devices 5 thus serve the purpose of horizontal adjustment of the roll 3 in a direction perpendicular to the axis of the roll 3 .
  • the adjusting devices 5 are arranged in such a way that they effect an adjusting movement in the direction of the arrow 6 perpendicularly to the axis 7 .
  • the adjusting device 10 in a rolling installation is formed by a pressure-medium actuator, such as a hydraulic actuator 11 , as shown in FIG. 2 .
  • the hydraulic actuator 11 is arranged between the roll 13 and the housing upright 12 in such a way that a pressure chamber 25 is formed between the component 23 and the component 18 .
  • a pressure medium can be admitted into the pressure chamber or placed under pressure, so that the two components 23 and 18 are acted upon to move away from each other and accordingly are shifted away from each other, or so that they move towards each other.
  • a piston 14 is held in a cylinder chamber 15 , 16 , so that two cylinders or chambers 15 , 16 are formed, into which pressure medium can be admitted, where the two chambers 15 and 16 are arranged on opposite ends of the piston 14 , so that pressurization of the chamber 15 applies pressure to the piston 14 in the direction of the roll, and pressurization of the chamber 16 applies pressure to the piston 14 in the direction away from the roll.
  • the piston/cylinder unit 14 , 15 , 16 creates a holding device or adjusting device, which is formed as a retaining cylinder and also serves to draw back the elements 20 , 21 and 23 .
  • the space 15 , 16 is formed in a housing 17 connected with the housing upright 12 . It is advantageous for the housing 17 to be formed as two parts comprising the subhousings 18 , 19 .
  • the piston is held in the housing 17 by its piston barrel, and its piston rod extends through an opening in the subhousing 18 , where it is connected with the roll bearing 20 . It can be advantageous also to provide an intermediate element 21 , which allows guidance in the direction perpendicular to the direction of movement of the adjusting device and perpendicular to the roll axis.
  • the cylinder of the space 25 is also formed by the elements 23 , 18 and is held in a recess of the block 17 .
  • the housing 17 also contains a sensor 22 , which directly or indirectly detects the position of the element 23 actuated by the cylinder 25 .
  • the sensor 22 has a pin 24 , which is supported on the element 21 or with the element 23 , which is connected therewith.
  • An especially advantageous aspect of this embodiment is the good controllability of the position by the pressurizable chambers or cylinders 25 and/or 15 , 16 , so that the position of the element 23 and/or of the piston 14 and thus the position of the roll 13 can always be adjusted in a well-defined way.
  • the embodiment shown in FIG. 2 has an especially compact construction, since the hydraulic unit with piston/cylinder unit 25 acts directly on the roll 3 .
  • the adjusting device 30 is formed by a pressure-medium actuator, such as a hydraulic actuator 31 , which acts on the roll 3 by means of a lever arrangement 32 , as illustrated in FIG. 3 .
  • the hydraulic actuator 31 is arranged between the roll 3 and the mill housing upright 33 in such a way that the piston 34 is held in a cylinder chamber 35 , 36 and forms two chambers 35 , 36 that can be acted upon by pressure medium, such that each of the two chambers 35 and 36 is arranged at one end of the piston 34 , so that pressurization of the chamber 35 acts on or moves the piston 34 to the right, and pressurization of the chamber 36 acts on or moves the piston 34 to the left.
  • the space 35 , 36 is formed in a housing 37 , which is connected with a housing 38 , which holds the lever arrangement 32 and in turn is mounted on the housing upright 33 .
  • the housing 37 is advantageous for the housing 37 to be formed as two parts comprising the subhousings 39 , 40 , where the part 39 is formed with a cuplike shape, and the part 40 is formed as a flange.
  • the flange 40 has an opening through which the piston rod 41 extends to bring about displacement of the roll 3 via the lever arrangement 32 .
  • a seal is provided in the region of the opening of the flange 40 .
  • the piston rod 41 is connected with an axially displaceable rod 43 , which is formed with a joint 44 , with which a lever arm 45 articulates.
  • the lever arm also articulates with the element 21 by means of another joint 46 .
  • This part 21 in turn is connected with the roll bearing 20 , so that a displacement of the element 21 is directly transferred to the roll 3 .
  • the piston rod 41 When the piston 34 is displaced due to pressurization of the pressure chambers 35 and/or 36 , the piston rod 41 is displaced and adjusted to a predeterminable position. This causes the rod 43 , for example, a connecting rod, and thus the joint 44 to be axially displaced. Since the roll bearing 20 is designed to be essentially fixed in the direction of the roll axis, the displacement of the joint 44 causes a change in the angular position of the lever arm 45 relative to the axis of the roll or to a perpendicular to the axis of the roll, and thus the distance between the housing upright 33 and the roll is defined and adjusted. So that the roller bearings 20 are essentially fixed in the direction parallel to the roll axis, they are locked by guides 47 that allow movement only in the direction perpendicular to the roll axis.
  • a sensor 48 is provided, which detects the position of the piston by means of a sensing element.
  • the head of the housing 39 is provided with an opening, through which the sensing element 49 of the sensor 48 can pass and enter an opening or drill hole in the piston.
