Definitions

  • the invention relates to a method for winding a toroidal core, wherein the toroidal core is rotated about an axis perpendicular to the ring plane.
  • This method has the disadvantage that the change in size of the toroidal core commencing after the start of the winding operation causes an eccentric position of the core to the wire magazine due to the applied windings.
  • the resulting eccentricity is greater, the thicker the wound wire is.
  • the hole in the center of the ring core must therefore be much larger than the cross section of the wire magazine used for this reason.
  • the known method for winding ring cores with a resulting residual hole in the size of the magazine cross-section used is not suitable.
  • the aim of the present invention is therefore to provide a method for winding a toroidal core, which allows the winding of small ring cores.
  • the invention provides a method for winding a toroidal core with a wire, wherein the winding of the toroidal core takes place in a stationary winding plane.
  • the toroidal core is held by a follower with the toroidal gripper and rotated about its axis perpendicular to the plane of the ring axis.
  • the method according to the invention has the advantage that the toroidal core is always held firmly by the gripper independently of its winding and thus eccentricities can be avoided.
  • the winding of the toroidal core can be carried out, for example, by means of a wire magazine, which also essentially has the shape of a ring.
  • the gripper can guide the toroid around or around the magazine clockwise or counterclockwise.
  • the area used by the gripper on the toroidal core can be kept small, and in an advantageous embodiment of the invention is only as large as it corresponds to the distance required for electrical insulation between two windings, so that by the gripper occupied area no restriction of Winding of the ring core results.
  • the gripper covered less than 4% of the circumference of the toroidal core.
  • care can be taken that there is no restriction for the winding of the toroidal core with windings, since a minimum distance must anyway be maintained between the individual windings for reasons of electrical insulation.
  • the gripper can be adapted to the minimum distance between two windings, so that a limitation of the windings is excluded by the gripper.
  • an abutment is arranged, through which the ring can slide and which absorbs the tensile forces of the wire occurring during winding.
  • the anvil is particularly required for gripper positions where the plane in which the gripper is located, is perpendicular to the winding plane. In this case, the torques generated by the Drahtzug mechanism, applied to the gripper occurring moments are greatest.
  • the method of winding a toroidal core can be further improved by controlling the gripper with a precise stepping motor.
  • an exact pitch specification that is, the necessary feed of the toroidal core in relation to the wire diameter also allows for multi-layer throttles.
  • the inventive method has the further advantage that even extremely small toroidal cores with an outer diameter ⁇ 4 mm, which can not be bewikkelt using the roller bearing, now the winding with automatic Bewicklungsmaschinen are accessible.
  • the winding can be done with thick wires or high number of turns.
  • the core can be wound with a very small or narrow gripper over an angle of at least 350 °.
  • FIG. 1 shows a ring core 1 in the form of a circular ring whose top and bottom is bounded in each case by a flat surface.
  • the ring core 1 is by means of a wire magazine 6, the in FIG. 1 is shown in section, and which extends perpendicular to the plane, wound in the stationary Wikkelebene 3.
  • the wound on the wire magazine 6 wire 2 is wound on the ring core 1.
  • the toroidal core 1 is moved by a gripper 4 which holds the toroidal core.
  • the curved arrow indicates the direction of rotation of the gripper 4.
  • On the gripper 4 opposite side of the wire magazine 6, an abutment 5 is arranged, which absorbs the bending moments resulting from the Drahtzug finallyn.
  • FIG. 2 shows the device after FIG. 1 , wherein about half of the winding process is completed.
  • FIG. 3 shows the device after FIG. 1 , just before the end of the winding process.
  • the counter bearing 5 is disengaged towards the end of the winding process by a movement indicated by the arrow, so that the gripper 4 can continue the core 1 in the winding direction and can approach close to the winding plane 3 , He assumes the support function of the thrust bearing 5. In this state, no large bending moments occur because the plane of the gripper 4 with the winding plane 3 includes only a very small angle.
  • FIG. 4 shows held by the anvil 5 ring core 1. Furthermore, various positions of the wound wire 2 are shown. The tensile forces F are in each case exercised in the wire direction. They generate a bending moment M, which is illustrated by the curved double arrow.
  • the ring core 1 can be stored in the counter bearing 5 by means of a ball bearing 7. But it is also possible to store the ring core 1 by means of a lubricious plastic in the anvil 5.
  • FIG. 5 shows the detained by the gripper 4 toroidal core 1, wherein the cutting plane is in the winding plane.
  • the wire 2 is shown schematically in various snapshots during winding.
  • the representation of the tensile forces F and the bending moment M corresponds to the illustration in FIG. 4
  • the gripper 4 may consist of two halves, which can be removed from the ring core 1 by pushing apart in the direction indicated by the double arrow, whereby the ring core 1 can be removed after the Bewicklungsvorgang.
