Definitions

  • the invention relates to a method for straightening wire or strip material by means of a dressing device with straightening rollers which act in an offset manner on opposite sides of the material passing through, some of which are automatically adjusted in such a way that the requirements for straightness are met, depending on a model which has been stochastically determined on the basis of input data of the material and data of the material and the dressing device determined as it passes through the dressing device, wherein the position of at least one straightening roller is continuously adapted on the basis of the said data recorded as it passes through the dressing device, which are representative of the straightness achieved.
  • the invention aims to provide a closed control loop for an autonomous process for straightening material of unknown, variable curvature.
  • the process should ensure the desired straightness of the straightened wire with greater reliability.
  • the temperature of the material is measured at the exit of each straightening roll or block.
  • the measurement (i) of the forces acting on the straightening rollers is conveniently carried out by means of strain gauges arranged on the bearing bolts of the straightening rollers, which measure the bending moments in axial, vertical and/or horizontal directions.
  • the measurement (ii) of the temperature records the deformation energy introduced into the material being straightened. This measurement can be used to correct material properties that are incorporated into the model. It is possible that this measurement is only carried out at the beginning of a straightening process or to calibrate a straightening device.
  • the measurement (iii) of the position of the material is carried out as described conveniently after each of the straightening rollers by measuring the deviation of the material from the throughput axis in the direction of the straightening rollers.
  • known optical or contactless (e.g. magnetic) Measuring method in question This also applies to the appropriate measurement of the vibrations occurring in the wire material passing through, the measured value of which is also entered into the model controlling the adjustment of the adjustable straightening rollers. It is conceivable that the position measurement (iii) is only carried out at the beginning of the process for calibration purposes, while during operation the measurement of the forces acting on the straightening rollers is sufficient to carry out the method according to the invention.
  • the material passes through two dressing devices as mentioned above one after the other, one dressing device having horizontally arranged straightening rollers and the other having vertically arranged straightening rollers.
  • the invention also relates to a device for carrying out the method according to the invention with a dressing device with two rows of driveless straightening rollers arranged longitudinally offset from one another, which during operation act on a wire running between the rows in order to straighten it, whereby some straightening rollers can be automatically adjusted to the material depending on a model so that the requirements for the straightness of the material emerging from the dressing device are met, whereby the model is determined stochastically based on input data of the wire and data of the dressing device and the material recorded in the dressing device.
  • a device is mentioned in the DE-A cited at the beginning.
  • the invention of such a device consists in that the straightening rollers of one row, which first act on the material, have fixed axes and the ones subsequently the straightening roller acting on the same side of the material can be adjusted individually to the material passing through, and that the straightening rollers of the opposite row can all be adjusted to the material, whereby the straightening rollers of this row which act on the material first can be adjusted together and the straightening roller of the same row which then acts on the material can be adjusted individually, and whereby the magnitude and direction of the forces acting on the straightening rollers can be measured by means of measuring devices arranged on these themselves, such as strain gauges, and/or the temperature of the material can be measured by means of measuring devices arranged at the inlet and outlet of the dressing device, and/or whereby means are provided for measuring the position of the material following each of the straightening rollers in the form of the deviation of the material from the passage axis in or parallel to the adjustment direction of the straightening rollers, whereby all measured values obtained can be fed to
  • the temperature of the material downstream of one or more straightening rollers can be measured by means of measuring devices arranged there, wherein all measured values obtained can also be fed to the model controlling the adjustment of the adjustable straightening rollers.
  • Fig.1 a training device with a wire running through it
  • Fig.2 the same dressage device with indicated measuring points of the forces occurring at the individual straightening rollers and the wire temperature
  • Fig.3 a straightening roller with a strain gauge attached to it.
  • the training device of the Fig.1 and 2 has two rows of horizontal straightening rollers 3, 4, 6, 10 arranged horizontally offset from one another. One row engages the wire to be straightened at the bottom and the other row engages the wire to be straightened at the top.
  • the material 1 to be straightened can also be strip material (not shown); in the following, the term material refers to the wire or strip material.
  • the straightening rollers 3, 4, 6, 10 have no rotary drive, the wire passes through the dressing device as material 1, which is moved in the direction of arrow 2 by feed rollers (not shown). Normally, the wire passes through two dressing devices one after the other, each offset by 90° to one another, with one dressing device having horizontal straightening rollers and the other dressing device having vertical straightening rollers.
  • the main working range of the invention covers wire diameters between about 4 mm and about 20 mm.
  • the first two straightening rollers 3 of the Fig.1 and 2 lower row have fixed axes of rotation.
  • the lower straightening roller 4 connected to this can be individually adjusted to the material 1 passing through by means of an adjusting device indicated at 5.
  • the first three straightening rollers 6 of the upper row can be adjusted together to the material 1 and for this purpose are mounted on a common carrier 7, the height of which can be adjusted by means of a lever 8 by a servomotor 9.
  • the upper straightening roller 10 connected to the upper straightening rollers 6 can be individually adjusted to the material by means of an adjusting device indicated at 11.
  • Fig.2 illustrates the measurements of the various forces acting on the individual straightening rollers, designated f, as well as the temperature measurements on the material 1 before and after passing through the arrangement of straightening rollers.
  • the material 1 is heated during straightening by a set of straightening rollers.
  • the temperature measuring devices are indicated at points 16.
  • the temperature measurement can also be carried out at the output of each of the straightening rollers 3, 4, 6, 10.
  • the measuring devices arranged after each of the straightening rollers 3, 4, 6, 10 for determining the position of the wire are in Fig.2 not shown. These are known optical or magnetic measuring devices which measure the deviation of the material 1 from the throughput axis in or parallel to the direction of adjustment of the straightening rollers 6, 4, 10, ie in the case shown in the vertical direction. Also not shown is a vibration measuring device which measures the vibrations occurring on the wire when straightening corrugated wires in order to eliminate the resulting disturbances.
  • Fig.3 shows a straightening roller 13 on a larger scale with strain gauges 17 arranged on its bearing bolt 12 in a groove 15.
  • strain gauges 17 are provided in the bearing bolt 12 of a straightening roller.
  • the strain gauges 17 are arranged parallel to one another in the bearing bolt 12. They are also arranged around the axis of the bearing bolt 12 at quarter-circle intervals (offset by 90°).
  • other pressure or bending measuring sensors can be used in or on the bearing bolt 12, e.g. piezo sensors with an equally simple design.
