Definitions

  • the invention relates to an adjusting cylinder for roll stands for rolling steel or non-ferrous metal.
  • Such pitch cylinders are used in strip rolling stands to adjust the rolling force and the work roll spacing.
  • the adjusting cylinders usually work on chocks that often act on the work rolls via several backup rolls.
  • a device of the type specified above is known, for example, from European patent EP 0 450 294 B1.
  • the percentage fluctuations in the rolling force should be kept small in the course of the rolling force control over the entire rolling force range.
  • a positioning cylinder is provided which has a plurality of piston surfaces and a hat piston guided in a cylinder collar.
  • the bottom of the hat piston forms a central piston surface, while the circumferential hat rim represents an edge piston surface.
  • the rolling stand can be used both for rolling with high forming forces and a large reduction in thickness and for rolling with low degrees of deformation, such as occur in skin pass rolling.
  • the known device has difficulty following rapid load changes and accordingly has poor control behavior.
  • the invention is based on the object of realizing in a simple manner an adjusting cylinder for rolling stands for rolling steel and non-ferrous metal, which can follow load changes more quickly in practical operation with a high control accuracy, particularly in the area of small rolling forces.
  • an adjusting cylinder for rolling stands for rolling steel or non-ferrous metal which has a cylinder housing which surrounds a cylinder space, with an actuating piston which is operatively connected to a movable part of the rolling stand and which has a pressure surface on its end face assigned to the cylinder space , and is equipped with an axially movable counter-piston which has a first pressure surface on its end face assigned to the pressure surface of the control piston and a second pressure surface on its side facing away from the pressure surface of the control piston, in a first position between the control piston and the counter-piston a first room defined and in a second position of the actuating and counter-pistons, at least one second space is delimited between a wall of the cylinder housing and the second pressure surface of the counter-piston, each space being assigned a pressure supply line for hydraulic fluid, via which the spaces are separated from each other with a pressure can be acted upon and wherein a pressurization of the first space with
  • the counter piston is axially displaceable in the cylinder housing.
  • the actuating piston of the actuating cylinder is operatively connected to work rolls of a roll stand.
  • the active connection can be conveyed in a manner known per se via at least one support roller and furthermore via at least one chock.
  • the pistons it is possible to switch between different positions of the pistons relative to one another and thus between different operating modes, a space being defined between the piston end faces in a first piston position, that is to say the entire area of the piston end faces is available for power transmission, and a space between is available in a second piston position the second, smaller pressure surface of the opposing piston and a housing wall is defined, that is to say a smaller surface is available for power transmission.
  • the first operating mode therefore comes with large forces, in particular when transmitting the rolling forces in rolling operation with a large reduction in thickness and a correspondingly large power requirement, while the second operating mode is used with small forces, in particular when the work rolls are turned on during skin pass rolling, this mode ensuring high control accuracy.
  • the spaces formed in each case can be pressurized separately via servo valves. This enables the valves to be optimally adapted to the force range to be transmitted.
  • the configuration according to the invention realizes a positioning cylinder for rolling stands in a small installation space, which ensures high control accuracy over the entire rolling force range, in particular in the range of small rolling forces.
  • the size of the pressure surface of the pistons can be adapted to the required rolling forces by means of the device. Thus, a large printing area is made available with large rolling forces and a small printing area with small rolling forces.
  • the relative control deviation from the desired pressure is small over the entire pressure range, since the absolute control deviation associated with the large pressure area has only a relatively small effect in the case of large force transmission, and a small pressure area is available for small force transmission stands, with which an absolute and therefore also relatively small control deviation is associated.
  • the counter-piston on its end face assigned to the pressure surface of the actuating piston can have a collar which lies tightly against the wall of the cylinder housing and on which the second pressure surface is formed.
  • the actuating piston can have a second pressure surface on its side facing away from the first pressure surface of the counter-piston, which is also arranged on a collar which bears tightly against the wall of the cylinder housing and on which the End face of the actuating piston assigned to the cylinder space is formed.
  • the actuating piston can also be axially displaceable in the cylinder housing.
  • a displacement of the actuating piston can then define a third space in the cylinder housing which is limited by the wall of the cylinder housing and the second pressure surface of the actuating piston.
  • a pressure supply line for hydraulic fluid can also be assigned to this space, via which the space can be pressurized separately via at least one servo valve.
  • the design of the pistons with the collar lying tight against the wall of the cylinder housing further improves the safe guidance of the components as they move in the cylinder housing.
  • the pressure that can be exerted on the first two spaces can be in particular in the range from 10 bar to 250 bar.
  • the pressure which can be applied to the third space is preferably below 5 bar, for example 3 bar.
  • the rolling forces transmitted by the pitch cylinder can range from 30 kN to 26000 kN.
  • the adjusting cylinder 1 is used in a roll stand, not shown, for cold rolling strips of steel or non-ferrous metal.
  • the positioning cylinder 1 has a cylinder housing 2 which surrounds a cylinder space 3.
  • a circular opening 4, 5 is formed in each of the cover 2a and the base 2b of the cylinder housing 2.
  • One end of a slidably mounted adjusting piston 6 is guided through the lower opening 5, while the end of a counter-piston 7, which is also slidably mounted, is seated in the upper opening 4.
  • the openings 4, 5 are aligned in alignment with one another in such a way that the pistons 6, 7 passed through them are aligned in axial alignment with one another.
  • Seals 8, 9, which are seated in the inner surfaces of the openings 4, 5 and bear against the respective outer surface of the pistons 6, 7, seal the cylinder space 3 tightly from the environment.
  • both the actuating piston 6 and the counter-piston 7 each have a circumferential collar 10, 11.
  • the opposite end faces of the collars 10, 11 are each aligned flush with the respectively assigned end face of the actuating piston 6 or the counter-piston 7.
  • a first hydraulic line 14 is guided through the counter-piston 7, the mouth of which is positioned centrally in the pressure surface 13 of the counter-piston 7.
  • a second hydraulic line 15 is guided to the side of the opening 4 through the cover 2a of the cylinder housing 2. Its mouth opening is molded into the inner surface of the lid 2a.
  • a third hydraulic line 16 runs through the bottom 2b of the cylinder housing 2, the mouth of which is formed laterally of the opening 4 in the inner surface of the bottom 2b.
  • the hydraulic lines 14, 15, 16 are each connected to a controller 17 via connecting lines.
  • the cylinder space 3 is moved from the collars 10, 11 into a pressure space 18, which is arranged between the pressure surfaces 12, 13 and extends over the entire diameter of the cylinder space 3, one between the cover 2a and the annular surface 19 assigned to the cover 2a of the collar 11 carried by the counter-piston 7 and an annular second pressure space 20 formed between the base 2b and the annular surface 21 assigned to the base 2b by the actuating piston 6 worn collar 10 formed also annular third pressure chamber 22 divided.
  • Fig. 1 the operating mode is shown in which the rolling stand is used for cold rolling with large rolling forces and large reduction in thickness of the respective rolled metal strip.
  • the counter-piston 7 rests with its annular surface 19 on the cover 2a of the cylinder housing 2.
  • the hydraulic line 15 is relieved of pressure.
  • the pressure space 18 defined between the pressure surfaces 12, 13 is acted upon by the hydraulic line 14 with pressure oil which is under the respectively required control pressure.
  • pressurized pressure oil is conducted into the annular pressure chamber 22 via the pressure line 16.
  • the back pressure exerted by this pressure oil on the actuating piston 6 via the annular surface 21 is a small fraction of the pressure which is exerted on the pressure surface 12 of the actuating piston 6 via the pressure oil contained in the large pressure chamber 18.
  • the pressure in the pressure chamber 18 is increased for this purpose. If necessary, the pressure chamber 22 is additionally depressurized in order to be able to exert maximum forces on the actuating piston 6. On the other hand, if the rolling force has to be reduced or the roll gap of the roll stand has to be increased, the pressure prevailing in the pressure chamber 18 is reduced. Supported by the back pressure acting in the pressure chamber 22, the actuating piston 6 is then actively moved into the respectively required position.
  • the required rolling force is exerted via the pressure oil which is filled in the upper annular pressure chamber 20 and acts on the annular surface 19 of the counter-piston 7, and is transmitted to the actuating piston 6 via the collar 11 of the counter-piston 7.
  • a counterforce is exerted by the pressure oil present in the lower annular pressure chamber 22, by means of which the actuating piston 6 with the counter-piston 7 resting on it is moved actively and within a very short reaction time into a raised position that corresponds to a wider gap of the roll stand can.
  • the pressure required in the respective operating mode in the pressure chambers 18, 20 and 22 is arranged in the control device 17, not shown here Regulated servo valves which are actuated as a function of control signals from the control device 17.
