Abstract
Description
(同芯巻コイルの構造)
図1~図4を参照して、本実施形態による同芯巻コイル10の構造について説明する。なお、同芯巻コイル10は、特許請求の範囲の「コイル」の一例である。
次に、図5~図13を参照して、同芯巻コイル10の成形装置100の構造について説明する。同芯巻コイル10の成形装置100は、平角導線11が複数回巻回することにより形成された同芯巻コイル10を成形するように構成されている。
本実施形態では、以下のような効果を得ることができる。
次に、図5、図6、および、図14~図23を参照して、本実施形態による同芯巻コイル10の成形方法について説明する。
図14に示すように、成形前の同芯巻コイル10が準備される。成形前の同芯巻コイル10は、平角導線11が複数回巻回することにより略六角形形状に形成されている。また、図15に示すように、成形前の同芯巻コイル10のコイルエンド部13は、湾曲していない(略直線形状を有する)。
次に、図16に示すように、第1移動機構部41により、外側金型20を同芯巻コイル10に対して相対的に移動させることにより、外側金型20の複数のフィン22の隙間21に同芯巻コイル10のコイルエンド部13を挿入することによって、フィン22の形状に沿うように、同芯巻コイル10のコイルエンド部13を湾曲させる。具体的には、同芯巻コイル10のコイルエンド部13がフィン22に対して摺動することにより、コイルエンド部13(第1コイルエンド部13a、第2コイルエンド部13b)がフィン22の形状に沿うように徐々に湾曲(図17参照)される。
次に、本実施形態では、図18および図19に示すように、第2移動機構部42により、分割された外側金型20のうちのスロット収容部12の一方側の外側金型201を、スロット収容部12の他方側の外側金型202に対して、平角導線11の積層方向Aに沿った方向(E方向)に相対的に移動させることによって、コイルエンド部13に、平角導線11の1本分の幅Wを平角導線11の積層方向Aにオフセットするように積層方向Aに屈曲するオフセット部分14(図3、図4参照)を形成する。具体的には、分割された外側金型20のうちのスロット収容部12の一方側の外側金型201を、スロット収容部12の他方側の外側金型202に対して、オフセット部分14の傾斜(傾斜部14c)に対して交差する方向E(図10参照)に相対的に移動させる。
次に、図20に示すように、コイルエンド部13にオフセット部分14を形成した後に、外側金型20を、同芯巻コイル10から離間するように退避させる。そして、図21に示すように、同芯巻コイル10の内周側に、内側金型30を配置する。なお、同芯巻コイル10の内周側に、内側金型30を配置する工程は、第3移動機構部43により行われる。
次に、本実施形態では、図22に示すように、内側金型30を外側金型20に対して相対的に移動させる。具体的には、第3移動機構部43により、内側金型30を外側金型20に対して近づくように移動させる。また、図23に示すように、第1移動機構部41により、外側金型20を内側金型30に対して近づくように移動させる。これにより、内側金型30(凸部33)により、同芯巻コイル10を外側金型20(凹部25)に押圧して、コイルエンド部13の頂部19を変形させる。その結果、凸部16(凸部16a、16b)が形成される。また、外側金型20の壁部26にも同芯巻コイル10が押圧されることにより、同芯巻コイル10の肩部17が形成される。また、内側金型30と、外側金型20との間の隙間の形状に沿うように、同芯巻コイル10のスロット収容部12の形状が変形(成形)される。具体的には、外側金型20の壁部26と、外側金型20の壁部26に対向する内側金型30の壁部34(図12および図13参照)とは、テーパ形状を有している。これにより、同芯巻コイル10のスロット収容部12を構成する平角導線11は、同芯巻コイル10の外周側(図1参照)に向かって、徐々にずれるように変形される。
本実施形態では、以下のような効果を得ることができる。
なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更(変形例)が含まれる。
