Definitions

  • the invention relates to a method and a device for aligning at least one lateral guide for laterally delimiting a transport path for a product, in particular for a rolling stock to be rolled, through a roller stand.
  • Such methods and devices are known in principle in the prior art.
  • European patent specification EP 3 365 120 B1 discloses a casting or rolling installation for producing or processing a cast strand.
  • the system has a transport path for the cast strand, with side guides being provided at the edge of the transport path for guiding the cast strand.
  • the side guides are moved in and out of the transport path transversely to the line of the transport path with the aid of actuators.
  • the European patent specification also discloses a method for measuring such a lateral guide using laser light in order to be able to determine the degree of wear in certain partial areas of the lateral guide.
  • Said measuring system is built into the casting or rolling plant and calibrated there before it is used.
  • the calibration initially means the fine adjustment or fine positioning of a light source, a receiving device and, if necessary, a reflector device with the aid of associated adjusting elements such that they are optimally aligned with one another and can interact.
  • the state of the art also includes the Chinese utility model CN 203370832 U, which primarily describes the structural design of a caliper for the parallel alignment of lateral guides at the edge of a transport path for slabs in particular.
  • the caliper also ensures that the respective distances from opposite lateral guide rails to the center line do not deviate from each other by more than 5 mm.
  • the object of the invention is to provide an alternative method and an alternative device for aligning at least one lateral guide for laterally delimiting a transport path for a product, in particular a rolled stock to be rolled through a roll stand
  • At least one lateral guide ruler is aligned parallel to the central axis of the transport path by the claimed method.
  • the claimed calibration of the at least one lateral guide ruler along the transport path advantageously ensures a uniform, homogeneous run of the product to be transported, ie in particular curvatures in the product are prevented.
  • the drive-side and operator-side lateral guides calibrated according to the invention are advantageously set parallel and aligned with one another by the method according to the invention, and the opening dimension of the lateral guides is calibrated in a common process sequence.
  • the claimed right-angled distance measurement, starting from the central axis of the transport path to the measuring points, which represent the points of action of the actuators on the lateral guide rails, can be carried out mechanically, by means of a laser or visually.
  • points of attack means “in the immediate vicinity", ideally in the middle of the articulated points of attack. Included in the A measuring point on the inside of a cornering guide at the shortest distance from the point of application of the actuator is also important.
  • the position of the measurement points is preferably chosen to be the same in relation to all points of application.
  • the parameter i designates a control variable; it describes the number of measurement points, the number of position sensors and the number of actuators. According to the invention, this is possible and useful because a position sensor and a measuring point must be assigned to each actuator; otherwise the method cannot be carried out with the respective actuator.
  • the claimed calibration method and the calibration of the opening dimensions of the lateral guides are particularly important during the initial assembly and commissioning of a roll stand, but also for later necessary realignments and calibrations, e.g. B. after maintenance shutdowns and after replacing various components of the system very helpful.
  • misalignments of the cornering guides due to dimensional deviations due to existing old system components and old foundations can be corrected by the design with independently adjustable rulers in conjunction with the calibration method according to the invention using the calibration method according to the invention.
  • each of the lateral guides is controlled by at least two actuators, which are offset in the longitudinal direction of the transport path and articulated on the lateral guide.
  • the actuators are advantageously articulated in each case on the (outside) side of the lateral guide rails facing away from the center of the transport path.
  • the insides of the lateral guides should be kept as smooth as possible to ensure that the product can slide along unhindered.
  • the actuators are according to the invention with the help of associated Position sensors, ie displacement sensors, preferably so-called Temposonics, individually controllable for position.
  • the step of defining the central axis of the transport path takes place in the following sub-steps:
  • a first reference point x and a second reference point y are established, both of which should lie on the center axis to define the center axis. Furthermore, a laser beam is preferably aligned as a reference axis along the central axis of the transport path defined by the reference points x and y.
  • a transport route can mean the entry in front of a roll stand, or the entry and the passage of the rolling stock through the nip of the roll stand, or the passage of the rolled stock through the nip and the exit from the roll stand, or the exit from the roll stand, or the entry in front of the roll stand , the passage through the roll stand and the exit from the roll stand.
  • the side guides can be arranged differently for all these variants of the transport path. For all of these variants, however, the method according to the invention offers a reliable option for calibrating the cornering guides or the actuators.
  • FIG. 1 shows the device according to the invention
  • FIG. 2 illustrates the method according to the invention.
  • FIG. 1 shows the device 100 according to the invention for aligning at least one lateral guide rail 20-1...20-4 for the lateral delimitation of a transport path for, in particular, a rolled product through a roll stand 40.
  • the roll stand 40 is abstracted in FIG. H. the longitudinal alignment of its rollers. This center line runs transversely to the transport direction T of the rolling stock. The direction of transport is also indicated in FIG. 1 by arrows from left to right.
  • Each individual lateral guide 20-1 ... 20-4 is controlled in an articulated manner by at least two actuators A1 ... A8. With these actuators, the angle of the lateral guide bar to the transport direction can be adjusted or aligned and it can be displaced transversely to the transport direction, ie into or out of the transport path.
  • a position sensor S1 . . . S8 is assigned to each actuator A1 . . . A8 for detecting the respective current position of the assigned actuator.
  • the individual actuators are controlled by a control device 120 which, according to the invention, is programmed to carry out the method according to the invention.
  • the sensors S1 . . . S8 report the respectively detected positions of the actuators back to the control device.
  • the device 100 according to the invention includes the actuators, the position sensors and the control device.
  • the lateral guide rails 20-1 ... 20-4 and the roll stand 40 are not part of the device according to the invention.
  • the method according to the invention according to FIG. 2 is used to align the lateral guides or to calibrate the actuators that control the lateral guides.
  • the term “cylinder” stands for “actuator” as an exemplary embodiment. It envisages the following steps: In a variant that is not shown, the calibration can also be carried out using inserts.
  • first reference point X and a second reference point Y both of which should lie on the central axis of the transport route, are defined.
  • the central axis itself is then preferably defined by aligning a laser beam as a reference axis along the central axis of the path defined by the two reference points X and Y; see method steps 1 - 3 in Figure 2.
  • the first reference point X is preferably set in the area of the start of a lateral guide
  • the second reference point Y is preferably set at the end of a lateral guide Y so that the two reference points X, Y are as far apart as possible . The greater the distance, the more precisely the transport route can be defined.
  • Step 4 of the method then provides that all lateral guides 20-1...20-4 are moved to a maximum opening dimension, ie their actuators A1...A8 are moved into their respective individual minimum extended position. In this minimum extended position, the lateral guide rails are each at a maximum distance from the central axis of the transport path. While step 3 of the method according to FIG. 2 can in any case only take place after steps 1 and 2, step 4 can also take place at any point in time before steps 1, 2 or 3 or during the execution of these steps. The method according to the invention is only necessary because typically not all actuators are pre-assembled at exactly the same distance from the central axis of the transport path and/or because they are self-contained have inaccuracies in the positioning or in their individual minimum extension positions.
  • the respective right-angled distances ai from at least 2 measuring points i with i>2 per lateral guide 20-1...20-4 the central axis of the transport route is determined.
  • the measurement points each represent the pivot points of the actuators A1 ... A8 on the lateral guide rails. Ideally, the measuring points are in the middle of the pivot points; In practice, the measurement points can also be selected on the inside of the respective lateral guide rails, preferably with the shortest distance from the respective associated pivot points. For reasons of a uniform measurement result, however, it makes sense if the measurement points are always determined in the same way on all cornering guides.
  • this method can be used for a wide variety of transport routes, i. H. for a wide variety of constellations of lateral guides in relation to a roll stand.
  • transport routes i. H. for a wide variety of constellations of lateral guides in relation to a roll stand.
  • lateral guides on the entry side of a roll stand are referred to as entry side guides and lateral guides on the exit side of a roll stand are referred to as exit side guides.
  • At least one inlet side guide ruler 20-2 is provided on at least one side along the inlet in front of the roll stand 40, viewed in the transport direction (T).
  • the transport route means the entry in front of a roll stand.

Abstract

L'invention concerne un procédé et un dispositif d'alignement d'au moins un guide latéral (20-1, ..., 20-4) destiné à délimiter latéralement un trajet de transport, en particulier pour des objets à laminer, à travers une cage de laminoir (40). Selon l'invention et à cet effet, l'axe central d'un trajet de transport doit d'abord être défini, puis tous les actionneurs (A1.., A8) du guide latéral doivent être déplacés dans la position déployée minimale respective des actionneurs. On détermine ensuite les distances perpendiculaires respectives (a1... a8) allant d'au moins deux points de mesure par guide latéral à l'axe central pour déterminer une course d'étalonnage individuelle pour chaque actionneur individuel à partir du minimum desdites distances perpendiculaires afin d'actionner le guide latéral. Enfin, chacun des actionneurs est étalonné en changeant sa position déployée individuelle, sur la base de sa position déployée minimale, afin de modifier la course d'étalonnage respective calculée pour l'actionneur respectif.
