Definitions

  • the invention relates to a method for straightening wire or strip material by means of a dressing device comprising straightening rollers engaging on opposite sides of the passing-through material in an offset manner, of which, some are automatically activated according to a model which has been stochastically determined on the basis of input data of the material and data of the material and of the dressing device determined during the passing of the material through the dressing device such that requirements for straightness are met, wherein the position of at least one straightening roller is continuously adapted on the basis of said data recorded during the passage through the dressing device, which data are representative of the target straightness.
  • the object of the invention is to provide a closed control circuit for an autonomous method in order to straighten the material to be straightened of unknown, variable curvature.
  • the method is intended to ensure the targeted straightness of the straitened wire with greater reliability.
  • the temperature of the material is measured at the output of each straightening roller or each straightening block.
  • the measurement (i) of the forces engaging at the straightening rollers expediently takes place by means of strain gauges arranged at the bearing bolts of the straightening rollers, which strain gauges measure the bending moments in the axial, vertical, and/or horizontal direction.
  • the measurement (ii) of the temperature records the deformation energy incorporated into the material to be straightened. Material properties flowing into the model can optionally be corrected by means of this measurement. It is possible that this measurement is only implemented at the start of a straightening process or to calibrate a straightening device.
  • the measurement (iii) of the position of the material expediently takes place following each of the straightening rollers by means of measurement of the deviation of the material from the pass-through axis in the positioning direction of the straightening rollers.
  • Known optical or contactless (e.g. magnetic) measuring methods are used for this.
  • This also applies to the vibrations occurring in addition for the expedient measurement of the wire material passing through, the measured value of said vibrations likewise being entered into the model controlling the adjustment of the adjustable straightening rollers.
  • the position measurement (iii) is implemented only at the start of the method for calibration purposes, while the measurement of the forces engaging at the straightening rollers in order to implement the method according to the invention is sufficient in ongoing operation.
  • the material passes through two dressing devices, as mentioned previously, in which one dressing device has horizontally arranged straightening rollers and the other has vertically arranged straightening rollers.
  • the invention moreover relates to a device for implementing the method according to the invention with a dressing device having two rows of non-driven straightening rollers arranged longitudinally offset opposite one another, which straightening rollers engage a wire passing between the rows during operation in order to straighten said wire, in which some straightening rollers are automatically controllably adjustable to the material depending on a model such that the requirements for straightness of the material exiting from the dressing device are met, in which the model has been stochastically determined on the basis of entered input data of the wire and on the basis of data of the dressing device and of the material recorded in the dressing device.
  • a device is mentioned in the previously cited DE-A.
  • the invention comprises such a device that the straightening rollers first acting on the material have a row of fixed axes and the straightening roller subsequently engaging the material on the same side of the material is individually adjustable to the passing-through material, and that the straightening rollers of the opposite row are all adjustable to the material, in which the straightening rollers of this row first acting on the material are jointly adjustable and the straightening roller of the same row subsequently engaging the material is individually adjustable, and in which the size and direction of the forces engaging the straightening rollers are measurable by means of these autonomously arranged measuring devices, such as strain gauges, and the temperature of the material is measurable by means of measuring devices arranged at the input and output of the dressing device, in which all obtained measured values are supplied to the model controlling the adjustment of the adjustable straightening rollers.
  • the temperature of the material subsequent to one or several straightening rollers is measurable by means of measuring devices respectively arranged there, in which likewise all obtained measured values can be supplied to the model controlling the adjustment of the adjustable straightening rollers.
  • the position of the material subsequent to one or several straightening rollers is measurable by means of measuring devices respectively arranged there, in which likewise all obtained measured values can be supplied to the model controlling the adjustment of the adjustable straightening rollers.
  • FIG. 1 shows a dressing device with a wire passing through it
  • FIG. 2 shows the same dressing device with indicated measuring points of the forces occurring at the individual straightening rollers and the wire temperature
  • FIG. 3 shows a straightening roller with a strain gauge arranged thereon.
  • the dressing device from FIGS. 1 and 2 has two rows of horizontal straightening rollers 3 , 4 , 6 , 10 arranged horizontally offset as relates to each other. One row engages the wire to be straightened from below and the other row engages the wire to be straightened from above.
  • the material 1 to be straightened may also be strip material (not shown); the term material in the following characterizes the wire or the strip material.
  • the straightening rollers 3 , 4 , 6 , 10 do not have a rotary drive; a wire as the material 1 passes through the dressing device, which material is moved in the direction of the arrow 2 by the feed rollers, which are not shown.
  • the wire passes through two dressing devices in succession, each of which is offset by 90° as relates to one another, in which one dressing device has the horizontal straightening rollers and the other dressing device has the vertical straightening rollers.
  • the main working range of the invention comprises wire diameters between about 4 mm and about 20 mm.
  • the first two straightening rollers 3 of the bottom row shown in FIGS. 1 and 2 have fixed axes of rotation.
  • the bottom straightening roller 4 attached thereto is individually adjustable to the passing-through material 1 by means of an adjusting device 5 as indicated.
  • the three first straightening rollers 6 of the top row are jointly adjustable to the material 1 and are mounted on a common support 7 for this purpose, which support is height-adjustable using a servomotor 9 by means of a lever 8 .
