Definitions

  • the invention relates to a setting device for hiring a roller in a roll stand of a roll stand, the adjusting device comprising a cylinder housing fastened to a roll stand and a translationally guided piston guided therein, wherein the position of the piston is determinable via a path measuring device connected to a coupling rod and a system comprising a roll stand and an adjusting device.
  • Adjustment devices are used to apply an object with force and / or to bring it into a specific position.
  • a setting device in a rolling stand is used to press a roller in the direction of its counter roll in order to be able to adjust the roll gap to one another by the position of the rolls, which defines the thickness of the strip emerging from the roll stand.
  • the adjusting device usually comprises a hydraulic cylinder with a cylinder housing and a piston guided in the cylinder housing, wherein the piston is held displaceable by pressure build-up in one of the pressure chambers arranged in the cylinder housing along a longitudinal axis relative to the cylinder housing , It goes without saying that the adjusting device can also perform restoring movements in addition to adjusting movements.
  • the hydraulic cylinder is connected for its function via pressure connections to a hydraulic system which via a control unit controls the pressure build-up and pressure reduction in the pressure chambers.
  • a displacement measuring device in operative contact with the piston is provided, via which the position of the piston relative to the cylinder housing can be determined.
  • a coupling rod is provided for this purpose, which on the one hand is connected to the displacement measuring device and on the other hand is connected to the piston by means of a spring element.
  • This spring element or the entire spring arrangement is disposed within the cylinder housing, so that it is accessible for maintenance purposes only at a complete disassembly of the hydraulic cylinder.
  • Other disadvantages of the prior art manifest themselves in the fact that the measuring accuracy decreases with increasing fatigue of the spring element;
  • prior art tilting devices tend to be susceptible to tilting, which causes measurement errors and incorrect position data. In a so-called tilting, there is a misalignment of the piston and the cylinder housing, in other words form at a tilt piston and cylinder housing no longer common longitudinal axis, but are offset at an angle to each other.
  • the invention relates to a setting device for adjusting a roll in a roll stand of a roll stand, the setting device comprising a cylinder housing which can be fastened to a roll stand and a piston which is displaceably guided in a roll stand, wherein the position of the piston can be determined via a path measuring device connected to a coupling rod.
  • the coupling rod is attached directly to the piston.
  • no bias of the coupling rod by spring element is more necessary because the coupling rod directly follows the movement of the piston.
  • the measuring device is connected directly to the piston via the coupling rod, so that the measurement results potentially falsifying elements between the piston and path measuring device are no longer available.
  • the piston has a guide element which extends from the piston head in the direction of the displacement measuring device and that the coupling rod is fastened to the guide element.
  • the guide element which may be formed, for example, as a piston rod with a circular cross-section, serves as part of an additional piston guide, which prevents tilting of the hydraulic cylinder and usually extends in a direction normal to the piston crown or along the longitudinal axis of the hydraulic cylinder. Since the coupling rod is mounted on the opposite side of the piston head of the guide element, the coupling rod can be made correspondingly shorter. It is advantageous if the guide element is arranged in the center of the piston crown and is formed symmetrically to the longitudinal axis. In alternative embodiments, however, it is equally conceivable that the coupling rod is attached directly to the piston head, wherein the guide element, so one is provided, is designed as a hollow cylinder and surrounds the coupling rod.
  • the guide element is guided in a guide opening of the cylinder housing. Since the guide element protrudes at least in sections through the guide opening out of the cylinder housing, the coupling rod is fastened to the guide element outside the pressure chamber of the hydraulic cylinder, so that assembly or disassembly of the coupling rod or the displacement measuring device can take place without prior disassembly of the hydraulic cylinder.
  • a sliding bush is arranged, through which sliding bush the guide element is guided.
  • the leadership of the guide element in the sliding bushing which preferably consists of plastic, further improves the piston guide, since friction effects are reduced and the slide bushing with the necessary precision is inexpensive to produce or can be purchased as if the guide is made solely by the guide opening.
  • the sliding bush also fulfills a sealing function to prevent the escape of hydraulic fluid from the cylinder housing.
  • the coupling rod is connected to the guide element via a play-free threaded connection.
  • the play-free threaded connection consists usually of a threaded hole and a threaded pin, wherein it has been found to be particularly advantageous if the threaded bore is formed in the top surface of the guide member and the threaded pin is formed by the coupling rod.
  • the freedom from play of the threaded connection ensures that the coupling rod itself follows small changes in the position of the piston immediately, without there being any micro-movement in the thread in the direction of the longitudinal axis, which would falsify the measurement result of the displacement measuring device.
  • an anti-rotation device such as an axial holder, which prevents rotation of the coupling rod about the common longitudinal axis. It is conceivable that the rotation is connected directly to the coupling rod or that the rotation is connected to the guide element.
  • a further preferred embodiment of the invention provides that the displacement measuring device in the operating state by means of a console on the opposite side of the cylinder housing of the rolling stand is fastened. Characterized in that the displacement measuring device is spaced from the cylinder housing and is fixed in the operating state on the other side of the rolling stand, a simple assembly and interchangeability of the displacement measuring device is given, since this is not in the cylinder housing itself. It goes without saying that in the case of another application under the roll stand any support element is understood to which the adjusting device according to the invention is mounted.
  • the console also called lantern, serves to accommodate the sensitive path measuring device and, for example via fasteners such as screws, attachable to the roll stand.
  • the path measuring device is protected by a cover against the environment.
  • the cover is either made of plastic, which has the site corresponding properties, such as high heat resistance, acid resistance or alkali resistance, or made of metal, such as steel or stainless steel. The cover thus protects the sensitive path measuring device from contamination, in particular from the penetration of solid particles or liquids. Furthermore, the cover also protects the path measuring device from mechanical damage.
  • the invention is provided in a further preferred embodiment that the console or the cover can be connected via a connection with a compressed air line to in a through Console and cover formed cavity to be able to set a relation to the environment increased pressure.
  • an overpressure in the cavity of between 0.1 bar and 3 bar, preferably between 0.25 bar and 1 bar, in particular of 0.5 bar, smallest foreign bodies are prevented from penetrating into the cavity. It goes without saying that any openings in the console or in the cover must be sealed or sealed in order to allow the formation of the overpressure.
  • the Path measuring device is designed for determining position via a magnetostrictive measuring method.
  • Magnetostrictive displacement measuring devices are per se known measuring elements, which are characterized by a particularly high accuracy and are largely insensitive to environmental influences such as temperature, vibration, shock and vibration.
  • the magnetostrictive displacement measuring device usually comprises a fixed base, a waveguide, a movable permanent magnet and a transducer which converts a mechanical vibration into an electrical signal. While the magnetostrictive displacement measurement is particularly advantageous, both optical, electrical and magnetoresistive measuring methods for determining the position of the piston are conceivable.

  • the console also called a lantern, also serves as a receptacle of the path measuring device connected to the end of the coupling rod. Therefore, a further embodiment provides that the displacement measuring device is attached via the console on the rolling stand, for example via a screw connection.
  • a sliding guide for the coupling rod is arranged at the end of the bore facing the displacement measuring device.
  • the sliding guide is preferably made of plastic and allows the linear guidance of the coupling rod with low sliding friction between the surface of the coupling rod and the slide, which is formed, for example, annular.
  • a further preferred embodiment of the invention provides that the bore is formed as a stepped bore, which at the end facing the cylinder housing sections has a larger diameter than at the opposite end to accommodate the guide element.
  • the guide element has the largest possible diameter, which is, however, limited due to the pressure to be built up in the pressure chamber.
  • the coupling rod since the radial guide forces are already absorbed by the guide element. So as to keep the weakening of the rolling stand through the hole as small as possible, the diameter of the bore over the remaining length of the bore is smaller and indeed so large that the coupling rod can be performed.
  • a positioning device according to the invention in a roll stand. Since particularly precise and reliable position data are required for adjusting and regulating the roll gap of a roll stand, the use of a robust and robust displacement measuring device according to the invention, which measures the position data of the hydraulic cylinder, improves the production quality while reducing the control effort. In particular, by the direct connection of coupling rod and piston results in particularly positive synergy effects. Thus, by the exact and unadulterated measurement of the position data of the adjusting device or the piston relative to, connected to the cylinder housing, roll stand a feed movement or return movement of the roller can be accurately controlled.
