Definitions

  • the present invention relates to a device for winding coils, in particular for transformers and chokes, according to the preamble of claim 1.
  • coils should each comprise one leg of two or more separate iron cores arranged adjacent to one another.
  • one of the above-mentioned coils is to be designed such that one or more sub-coils are present within the coil, each of the sub-coils comprising only a single one of the legs of the adjacent iron cores, and an outer coil being arranged above these sub-coils, whose winding encloses all these partial coils together.
  • Preferred embodiments of the device according to the invention comprise the features of the dependent claims.
  • each of the sub-coils required is expediently set to each a winding support body adapted to the leg of the corresponding iron core, which is either a winding template, a winding mandrel, a flangeless bobbin or a flanged single or multi-chamber bobbin.
  • a winding device of the previous type is required, with which the winding support body can be gripped, rotated and the required number of turns of the winding wire can be wound up.
  • the partially wound winding support bodies of the partial coils are now placed on the device according to the invention for winding coils, such that one winding support body is pushed over each of the winding receiving elements.
  • the outer coil comprising all the winding support bodies is wound.
  • each of the winding receiving elements expediently corresponds to the cross section of the iron core for which the respective winding support body is intended.
  • the distance between the winding receiving elements is set in accordance with the distance between the individual legs of the iron cores which the coil arrangement is to comprise.
  • DE-C-805767 discloses a coil winding device which comprises a disk-shaped winding head which is provided on one side with a hub for attaching the winding head to a driving shaft and on the other side has winding mandrels with wire guides which are spaced apart from one another. The mutual distance between the mandrels can be changed.
  • the coil winding device serves to lift coils wound without a bobbin by engaging the winding mandrels against the center of the winding head from the wire guides to be able to.
  • a clamping or clamping device 1 is used to clamp the winding device in a jaw chuck, a collet or another clamping device or to clamp onto the face plate on the rotatable part of the winding machine, winding or lathe.
  • a cross member 2 is preferably detachably mounted on the clamping or clamping device 1.
  • At least two winding receiving elements 3 serve to receive already partially wound and / or unwound winding templates, winding mandrels, flangeless bobbins or flanged single or multi-chamber bobbins.
  • the winding receiving elements 3 are preferably detachably mounted on the side of the crossmember 2 facing away from the clamping or clamping device 1.
  • the distance between the individual winding receiving elements is preferably adjustable. This can be done by means of slots which are made in the crossmember 2 and along which the winding receiving elements 3 are displaceable.
  • Clamping devices 4, for example consisting of a nut, spring washer and washer, are used to mount the winding receiving elements 3 on the cross member 2 and are tightened by a winding extension of each winding receiving element.
  • the structure now assembled can now be clamped or clamped on the winding machine, winding or lathe, then centered and / or guided and is now ready for the winding process.
  • the geometrical dimensions and design of the winding device according to the invention are determined by the geometrical dimensions and shapes of the coils to be wound.
