[0007] However, in the coil manufacturing method of Patent Document 2 mentioned above, since it is necessary to sequentially change the length of each turn, a special winding drum with different turn lengths is required. If the size of the coil or the number of turns is different, Then, it is necessary to prepare a plurality of reels corresponding to the size of the coil or the number of turns or their dedicated winding jigs, which has the disadvantage of increasing the management burden of the reels or winding jigs.

[0037] Next, the best mode for carrying out this invention is demonstrated based on drawing.
[0038] Figure 20 The stator 10 of the motor is represented. The stator 10 includes a cylindrical stator core 11 and a stator coil 12. The stator core 11 includes a plurality of teeth (magnetic poles) 11a radially arranged and protruding in the inner diameter direction, and a plurality of slots 11b opened between the plurality of teeth 11a. . The coil side portion 13 inserted into the slot 11 extending in the axial direction of the inner circumference of the cylindrical stator core 11 and the coil end protruding from the slot 11b in the axial direction of the stator core 11 and bent along the outer circumference of the stator core 11 The portion 14 is continuous in the circumferential direction to form the stator coil 12 . Then, the plurality of coil side portions 13 of the stator coil 12 approach each other and become narrower. In this state, the stator core 11 is inserted, and t...

The present invention provides a coil manufacturing device which can perform metal wire forming without coil reel or coil winding clamp, etc., and can easily change the bending machining point and the bending degree. The coil manufacturing device is provided with the following components: a through and straight wire guiding nozzle (21) which supplies a metal wire (16) that extends from a supplying source (17); a metal wire conveying device (22) which is provided at a back end of the wire guiding nozzle and supplies the metal wire (16) to the wire guiding nozzle for discharging the metal wire from the front end of the wire guiding nozzle; and a machining device which bends the metal wire that projects from the front end of the wire guiding nozzle frontwards for forming a coil (12) in whicha coil edge (13) and a coil end (14) are continuous. The wire guiding nozzle is formed longer than the nozzle edge. The wire guiding nozzle is equipped at a space in front of the metal wire conveyingdevice with a mode that the machining device can form the coil at the front and surrounding space of the wire guiding nozzle. The metal wire which projects frontwards from the front end of the wire guiding nozzle is bent for forming the coil with continuous coil edge and coil end in a circumferential direction at the front and surrounding space of the wire guiding nozzle.
Description
technical field [0001] The present invention relates to a coil manufacturing apparatus for manufacturing a coil used for a stator or the like by bending a metal wire. Background technique [0002] Conventionally, a stator for a rotating electrical machine includes a cylindrical stator core having a plurality of teeth (magnetic poles) arranged radially and protruding in the inner diameter direction, and a plurality of slots opened between the plurality of teeth, and a stator coil formed by connecting The coil edge is accommodated in the slot and assembled on the iron core. Regarding the assembly of the stator coil, there is known a so-called insertion method in which the stator coil and the stator core are separately manufactured in advance, and then the coil is accommodated in each slot of the core. In addition, among the coil winding methods used in this insertion method, there are known a lap winding method in which a wire is wound around the teeth, and a wave winding met...
