Definitions

  • the invention relates to a lacquer-coated wire with non-circular cross-section, two methods for producing the wire, a coil produced therefrom and a method for the production thereof in accordance with the preambles of the independent claims.
  • lacquer-coated wires of round cross section for the production of electric coils are known. These wires are made of copper, aluminum or another metal or a metal alloy, and have an inner electrically insulating coating and disposed thereon, an outer baked enamel layer.
  • the first, inner, paint coating which consists of polyurethane or polyester amide, is used for electrical insulation of the wire.
  • the second, outer, lacquer layer which is called by the wire manufacturers Backlack, serves a mechanical connection between the turns and the winding layers. It is made of paints that allow a subsequent softening of the paint layer.
  • the softening of the lacquer layer can be done either by the action of heat or by the action of a chemical solvent.
  • paints based on polyvinyl butyral or polyamide are used.
  • non-circular cross-sections relate to oval and rectangular cross-sections, the latter having rounded edges, thus having the initially defined cross-sections, which have two axes of different length and of normal length.
  • Such wires are used for the production of electric, self-supporting coils.
  • these coils with a round cross-section wire have the disadvantage that between the adjacent wires remain free spaces. These gaps cause a reduced packing density, which reduces the efficiency of the device in which the coil is used.
  • the individual wires of such coils are only on narrow lines of contact, which also, since such coils are subjected to the electromechanical forces, the durability of such coils is impaired.
  • the lacquer coating and thus also the outer baked enamel layer are applied to the wire in different thicknesses distributed over the rectangular areas, and the wires cake together only in relatively narrow contact areas, the package cohesion of the individual wires in the coil is not optimal. As a result, the service life and the mechanical self-carrying capacity of the coil are in turn severely impaired.
  • the object of the invention is now to provide a non-round lacquer-coated wire, which does not have the disadvantages of these wires mentioned.
  • the wire has a cross section with an axial ratio of not more than 3: 1, wherein it is rectangular or advantageously oval cross-section.
  • the advantage of such a wire according to the invention is that its design enables the production of an electrical coil in which the adjacent wires are close together and caked together over a large area. Due to the fact that the layer thickness of the paint coating of the wire at the shorter cross-sectional axis to be assigned sides stronger, preferably much stronger, than at the longer cross-sectional axis attributable sides, it is in the production of coils of lacquer-coated wires in particular oval cross-section possible at to largely fill the array of wires adjacent gussets with varnish coating material.
  • the coil production is carried out under heating so that paint coating material becomes plastic and so the gusset spaces forming in particular in the area of the shorter transverse axis of the wire can be filled by the paint coating compound present here to an increased extent. Due to the substantially uniform layer thickness of the lacquer coating on all sides or surfaces of the wire according to the invention, a close arrangement and caking of the lacquer-coated wires of rectangular cross section in the production of coils is ensured in any case.
  • the invention also relates to a method for producing a wire having a non-circular cross-section, which has two axes of different lengths, normal to each other and from a metal wire and a surrounding paint coating having insulating and baked paint properties.
  • This method is according to the invention characterized in that the paint-coated wire round cross-section by rolling on a cross section with a maximum axial ratio of 3: 1 is pressed .. According to a preferred embodiment, the wire is pressed to an oval cross-section.
  • the process according to the invention is preferably carried out in such a way that the paint-coated wire of round cross-section is carried out between two correspondingly spaced rolls. It is just essential that the nip is adjusted so that the ratio of the two different lengths, perpendicular to each other cross-sectional axes 3: 1 of the deformed wire is not exceeded.
  • lacquer-coated wires whose lacquer coating is in each case constructed from an inner electrically insulating insulating layer and an outer baked enamel layer.
  • lacquer-coated wires whose lacquer coating is in each case constructed from an inner electrically insulating insulating layer and an outer baked enamel layer.
  • a single-coat paint coating can also be used, which simultaneously has insulation and baked-on properties.
  • Fig. 1 shows a conventional lacquer-coated wire 1 'round cross section, wherein the metal wire 2' with an inner electrically insulating lacquer layer 3 'is sheathed. Over this lacquer layer 3 ', an outer, second baked enamel layer 4' is arranged, which serves a connection between the wires of electrical coils made of these. Such a coil 5 'is in Fig. 2 shown.
  • the contacting paint-coated wires 1 ' are on along relatively narrow lines of contact with each other via the baked enamel layer connected. However, between the wires 1 'remain free spaces 6', which bring a reduced packing density with it.
  • Fig. 3 shows a lacquer-coated wire 1 "of rectangular cross section according to previously known prior art
  • Such coated wires are conventionally made so that a metal wire of round cross-section is pressed or pressed and formed into a wire 2" of rectangular cross-section.
  • An electrically insulating lacquer coating 3 "and then a baked enamel coating 4" are then applied to the deformed metal wire 2 "due to the lack of symmetry of the cross-sectionally substantially rectangular wire 2", these wires have coatings of non-uniform thickness as a result of the production in particular on their broad sides, coatings 3 ", 4" sometimes irregularly outwardly cambered outer surfaces.
  • a wire 1 of oval cross-section produced according to the invention which consists of a metal wire 2, an electrically insulating coating 3 surrounding it and an outer baked enamel layer 4 applied thereto.
  • a continuous gentle pressing of a lacquer-coated wire round cross-section which can be produced according to the given symmetry with lacquer coatings in uniform thickness, to an oval cross-section with a ratio of two different lengths, vertically stacked Querterrorismsachscn of a maximum of 3: 1 finally shows the depressed coated Wire 1 on all sides in each case coatings in steplessly uniformly extending thickness.
  • the surface of the coating is substantially smooth.
  • the electrically insulating coating 3 and the outer baked enamel layer 4 each have an average thickness of between 5 and 10 ⁇ m.
  • the invention makes it possible to eliminate a disadvantage of the wires of non-circular cross-section in the use of electric coils. Such wires tend to break at the points where they exit the coil assembly. They are much more vulnerable in this respect than round wires. The reason for this vulnerability presumably lies in the increased punctual dynamic stresses in this area, to which non-circular wires oppose less resistance than round ones, but the causes are not explored in the last consequence.
  • the inventive method it is possible by the inventive method to produce the coils of a wire 1 ', which in the area in which it is guided by the (not shown) connection point freely to the coil (section XX, Fig. 10 ), the loop 7, and in an initial region 8 on the spool 9, which does not exceed one turn and is preferably less than half a turn, to leave round and to produce only the actual spool of the inventively formed wire 1.
  • the transition from the round wire 1 'to the non-round wire 1 in the area between the sectional planes VIII-VIII and IX-IX, as shown in the 8 and 9 is apparent.
  • the invention relates both to a coil of a wire according to the invention, which is characterized in that the coil consists essentially of wire non-circular cross-section and that at least one of the feed wires (loop) to the coil has round cross-section and over a maximum of one turn, preferably maximum half a turn, with a round cross-section is part of the coil; as well as a method for producing such a coil, characterized in that between a supply reel for the round wire and the guide device for the supply of the wire to the casserole point on the spool are arranged forming rollers for deforming the wire which, between an active position, in which they displace the continuous wire and an inactive position in which the wire passes through and remains round, are adjustable, and that the forming rollers are in the active position when passing through sections of the wire, from which the coil is formed and that in be brought to the inactive position when passing through wire sections, from which a loop or the transition from the coil to the loop is formed.
