Claims (3)
- 導体線を折り返すことによって、山型状のコイルエンド部と、前記コイルエンド部の両端にそれぞれ接続される直線部と、を有する導体を成形する導体成形方法であって、
前記導体線に対して、前記導体の前記コイルエンド部の頂点に対応する部位を支点として折り返す動作を開始し、折り返される一方側の前記導体線が折り返される他方側の前記導体線に完全に重なり合う前に折り返し動作を終了する一次折り返し工程と、
前記一次折り返し工程の終了後に、前記導体の前記コイルエンド部と前記直線部との境界部に対応する部位を支点として、折り返される一方側の前記導体線を、折り返される他方側の前記導体線に対して、前記直線部の延び方向に対して交差する方向に相対的に移動させ、前記頂点を境にして前記導体線を斜行させる一次斜行工程と、
前記一次斜行工程の終了後に、折り返される一方側の前記導体線が折り返される他方側の前記導体線に重なり合うようにさらに折り返す二次折り返し工程と、
前記二次折り返し工程の終了後に、折り返される一方側の前記導体線を、折り返される他方側の前記導体線に対して、前記一次斜行工程と同じ方向に相対的にさらに移動させることによって、前記コイルエンド部を成形する二次斜行工程と、を備える、導体成形方法。 - 一定の間隔で並列させた複数の前記導体線に対して、前記一次折り返し工程、前記一次斜行工程、前記二次折り返し工程及び前記二次斜行工程を複数回ずつ順次繰り返すことによって、前記直線部の延び方向の両端部側にそれぞれ前記コイルエンド部を形成して、帯状の前記導体を成形する、請求項1に記載の導体成形方法。
- 複数回の前記一次折り返し工程及び前記二次折り返し工程は、前記複数の導体線を、前回の前記一次折り返し工程及び前記二次折り返し工程の折り返し方向と反対方向に折り返す工程を少なくとも1回含む、請求項2に記載の導体成形方法。
