Incorrect settings can have a negative impact on the straightening quality or the straightness of the cable. Incorrectly set straightening devices 1 can lead to inaccurate stripping lengths or have a negative impact on the quality of the crimp connection.

Thanks to this display device, the user who actuates the setting device 6 can be guided in an intuitive manner with regard to the setting of the directional parameters.

  • the lower roller plate 17 is rotatably supported about an edge axis 27.
  • the axis 27 is arranged next to the axis of rotation of the last roller 20.6 of the lower row 3 of rollers.
  • the lower roller plate 17 with the first roller row 3 can thus be inclined relative to the upper roller plate 18 with the second roller row 4 by the aforementioned rotary movement about the axis 27.
  • the rollers in this case press more strongly on the input side onto the cable 2, which is pulled through the straightening device 1.
  • the straightening device 1 thus brings about a directional effect which decreases in the transport direction x of the cable 2 from the first rollers 20.1, 21.1 to the last rollers 20.6, 21.7.
  • the pneumatic cylinder 9 can be controlled via a valve.
  • the pressure of the pneumatic cylinder 9 and thus the force that presses on the cable 2 on the input side can be adjusted via a pressure regulator.
  • the angle between the roller lines predetermined by the rollers of the roller rows 3, 4 is the second straightening parameter.
  • This angle can be set with the aid of the pneumatic cylinder 9 described above or by means of an adjusting device (not shown) which can be operated manually, if necessary, for pivoting the lower roller plate 17.
  • the angular position between the rows of rollers 3, 4 could be set to a fixed value, which is generally between 0 ° and 5 °.
  • screws (not shown) can be used, for example, which can be guided in a corresponding elongated hole when the lower roller plate is pivoted.
  • the angle can also be detected by a measuring device and this measuring device can be connected to the control device 7 and a display device in such a way that an incorrect angle position is displayed to the user.
  • a measuring device for example, after having set the correct roller spacing in a first set-up phase, the user can set the angle by means of the adjusting device for pivoting the lower roller plate. Thanks to a corresponding display device, which can be implemented analogously to the display device already described and assigned to the roller spacing, the angle can be set easily and without great effort.
  • an automatic execution EP 2 399 856 A1 which has comparatively high requirements and is therefore expensive, could be dispensed with.
  • a socket 30 can be seen.
  • the plug socket 30 can be, for example, a digital interface to the control device (not shown).
  • the measuring device 6 for detecting the distance between the rolls of the upper and lower row of rolls communicates with the control unit via this interface.
  • a compression spring 16 recognizable.
  • the 5a and 6a show the straightening device 1 in an open position.
  • the rollers of the two rows of rollers 3, 4 are spaced so far apart that a sufficiently large space is created through which the cable can be inserted.
  • the rows of rollers are preferably first shifted against one another in the vertical direction by means of a quick-release device comprising the quick-release lever 31.
  • the parallel rollers of the upper and lower roller rows 3, 4 are close to the cable, so that the actual setting of the straightening device 1 can now be started.
  • the user can now turn the knob 19 of the adjusting device 5 clockwise, whereby the upper roller plate 18 is moved with the upper roller row 4 down against the lower roller row 3.
  • the user executes this relative infeed movement by manually actuating the setting device 5 until the rollers 20.1 .. 20.6 of the first row of rollers 3 and the rollers 21.1 .. 21.7 of the second row of rollers 4 contact the cable 2.
  • the user can determine the approximate contact by eye. Then he checks the display device 8. If the error display element 22 lights up red, then the rows of rollers 3 and 4 are still too far apart. In other words, the measured actual value for the distance d between the rollers 20.1 .. 20.6 and the rollers 21.1 .. 21.7 of the first or the second row of rollers 3, 4 compared to the target value for the roller distance d is too high.
  • the user On the basis of the display device 8, the user is thus indirectly instructed to continue to turn the rotary knob 19 in the same direction of rotation. He does this until the good display element 24, which illuminates the display device 8 green. A good signal is generated which indicates that the actual value of the roller distance corresponds to the corresponding target value. If the user turns the rotary knob 19 for too long, the error display element 23 lights up red due to the insufficient roller spacing.
  • the measured value for the roller distance d is shown on a digital display 25, the three LEDs of the error display elements 22, 23 and the good display element 24 signal to the user whether he should close or open the straightening device 1 in order to achieve the desired setpoint for the roller distance.
  • the operator turns the rotary knob 19 until the green LED of the good indicator element 24 lights up when the desired value is reached.
  • the control unit 7 assigned to the machine control then releases the production of the cable.
  • the active position in which the straightening device 1 is correctly set is in 5b and 6b shown. If necessary, after setting the roller spacing, the angular position of the roller rows 3, 4 can be changed in a conventional manner by switching on or automatically actuating the pneumatic cylinder 9. The angular position of the rows of rollers 3, 4 could, however, also be changed manually after a corresponding redesign of the straightening device 1 and set in an analogous manner to the roller spacing.
