Definitions

  • the invention relates to a method for controlling and regulating the drive speed of drawing disks in a multi-stage, smooth and straight pull wire drawing machine in which a drawing disk is assigned to each drawing die and each drawing disk is driven by a speed-controlled or speed-controlled drive.
  • wires are drawn from the drawing disks by means of drawing tools without axial twisting on straight-line drawing machines which operate without sliding and without wire accumulation.
  • Each drawing disk has an individual drive which adapts the drive speed of the drawing disk to the respective wire extension by means of corresponding electrical or mechanical control devices.
  • Multi-stage wire drawing machines are used, in which the working speed of the drawing disks is regulated via the wire tension by means of so-called dancer rollers, which are located on tensioning arms and steer the wire during the transition from a drawing disk to the following drawing tool, in order to control the intervention by changing the wire tension Trigger the drive of the pull washers.
  • a wire drawing machine of this type can be seen, for example, from DE-PS 1 072 216.
  • the steplessly variable transmissions which are adjustable by the wire tension and act on the individual drawing disks are connected in series in such a way that the output speed of one is the input speed of the other.
  • the drive of a controllable drawing disk is derived on the output side of each transmission.
  • An increase in the wire loop by increasing the speed of the upstream drawing disk triggers a control process, which causes an increase in the basic speeds of all the drawing disks upstream of the control point while maintaining their specified speed ratio without taking up the control range of the continuously variable transmission.
  • Multi-strand wire drawing machines in which the drive speed of the drawing disks over the wire tension using dancers or Tracer rollers are regulated, have the advantage over the direct pulling wire drawing machines that the working speed of the drawing disks adjusts itself automatically.
  • the object of the invention is to provide a method for controlling and regulating the drive speed of drawing disks in a multi-stage, smooth and straight pull wire drawing machine of the generic type, which with regard to starting without manual intervention, an automatic, reliable setting of the speeds and reproducible Counterforce enabled.
  • the object is achieved in that in the start-up phase of the wire drawing machine, the adaptation of the speeds of the individual drawing disk drives to the process-related parameters (wire diameter or wire cross-section decrease) in a setpoint cascade via a feeler roller position control, which automatically adjusts the setpoint cascade, the adjustment being proportional to the speed ratios of the drawing disk drives and independent of the absolute speeds or setpoints, and that the feeler rollers are slowly moved to an end position via a control command to the feeler roller position control continuous transition to the direct straight pull and the further regulation of the drive speed is taken over by the known counter pull regulation or control method in the straight pull and the feeler rollers are controlled out of the wire area.
  • 3 feeler rollers 4 are installed between drawing disks 2 and drawing dies.
  • the drawing disks 2 are driven in a rotating manner by means of speed-controlled drive devices 7 with drive control 8.
  • To retract the wire drawing machine is started after threading the wire 1 as in drawing machines with dancer or feeler rollers, the wire drawing machine initially running at a minimal production speed.
  • the speed of the individual drawing drives is adjusted to the process-related parameters (wire diameter or wire cross-section decrease) in a setpoint cascade via a feeler roller position control, which automatically compares the setpoint cascade, the adjustment being proportional to the speed ratios of the drawing disk drives or Cross-sectional ratios of the wire and independent of the absolute speeds or setpoints.
  • the feeler rollers 4 reach the desired position (a) near the stretched wire guide via the feeler roller position controller 11 in accordance with the desired value (A).
  • the feeler rollers 4 are slowly and smoothly steered out of the area of the wire 1 and reach the end position (b). Removing the tracer rollers from the wire area leads to a considerable reduction in wear on the rollers.
  • the feeler roller position controller 11 is switched on or adapted to its new task as a counter-tension controller.
  • the feeler roller restoring force is set via a control command before the command "move tracer rollers to end position", so that the desired counterforce is generated via the corresponding angle.
  • the feeler roller position controller 11 is switched on as a counter-pull controller.
  • the feeler rollers 4 are slowly steered out of the area of the wire 1 and reach position (b). Controlling the feeler rollers 4 out of the wire area leads to the fact that the pull drive with the controller 11 registers the relief and adjusts until the old pull in the stretched wire position (straight pull) is reached again.
  • the feeler roller position controller and the counter-pull controller are connected in cascade and each of the controllers is arranged as a subordinate control loop or the feeler roller position controller and the counter-pull controller are designed as parallel controllers. Furthermore, the feeler roller position controller and the counter tension controller are implemented with a single adaptive controller, in which the respective parameters (proportional gain and readjustment time) are switched according to the operating mode (touch roller controller or counter tension controller) and a bumpless transition takes place in the wire by selecting the transition behavior.
