イル素線の絶縁皮膜を剥離する装置を提供せんとするも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coil forming device for a coil tube used in a mini motor, etc., and it is an object of the present invention to provide a device for peeling off the insulation coating of the coil wire located on the end surface of the coil tube. .

続する場合のタップ相当部２に相当するコイル筒１の端
部におけるコイル素線１を剥離している。As shown in FIG. 1, in the coil tube 1 obtained by winding the coil wire 6 into a cylindrical shape, the coil tube 1 corresponds to the tap equivalent portion 2 when connecting the coil wire 6 and the commutator. The coil wire 1 at the end is peeled off.

い難いという欠点があつた。この発明は上記欠点を除去
せんとするものである。However, in the past, since the coil wire 6 was simply wound into a cylinder, the end of the coil tube 1 was not flat, but had wavy and uneven surfaces, and as a result, the tap-equivalent portion 2 was not vertically aligned. There was a drawback that it was difficult to connect the tap equivalent part 2 and the commutator. This invention seeks to eliminate the above drawbacks.
以下、この発明を実施例図面に基づいて説明する。Hereinafter, the present invention will be explained based on the drawings of the embodiments.

It is a partially cutaway sectional view.
図において、１はコイル素線を巻装して筒状にノ形成し

膜は剥離されてタップ相当部２を一定間隔をおいて複数
個形成している。In the figure, reference numeral 1 denotes a coil tube formed into a cylindrical shape by winding a coil wire, and the insulation coating of the coil wire corresponding to the end portion is peeled off to form a plurality of tap portions 2 at regular intervals. Individually formed.
３は芯金、４は半円筒状の凹溝４ａを備えたプレス型、
５は剥離型である。3 is a core metal, 4 is a press mold equipped with a semi-cylindrical groove 4a,
5 is a peelable type.

しており、往復運動又は回転運動をする金型である。次
に、本発明コイルフォーミング装置について説明する。The peeling mold 5 is a mold that has a roughened upper surface with a file-like shape, and performs reciprocating or rotating motion. Next, the coil forming apparatus of the present invention will be explained.
コイル筒１を剥離型５の上に載置したのち、該コイル筒
１の内空部に芯金３を挿通し、かつ該コイル筒１の外周
から左右のプレス型４を互いに近ずけて、その凹溝４ａ
の内面でコイル筒１を縮径させる。プレス型４を作動後

その表面に密着する。しかるのち、その剥離型５を左右
に矢印Ａの如く若干移動、又は矢印Ｂの如く若干回動さ
せる。After placing the coil tube 1 on the peeling mold 5, the core metal 3 is inserted into the inner space of the coil tube 1, and the left and right press molds 4 are brought close to each other from the outer periphery of the coil tube 1. , the groove 4a
The diameter of the coil cylinder 1 is reduced on the inner surface of the coil cylinder 1. After the press mold 4 is operated, the peripheral wall of the coil cylinder 1 is held between the core metal 3 and the press mold 4 and is tightly attached to the surface thereof. Thereafter, the peeling mold 5 is slightly moved left and right as shown by arrow A, or slightly rotated as shown by arrow B.
コイル筒１の端面は剥離型５の粗い面に接しているから
、コイル素線６の絶縁皮膜を剥離し、あるいはその端面
を若干切削する。本発明のコイルフォーミング装置はこ
のようにして、コイル筒の周壁をプレス型と芯金とで挟
持し、該コイル筒の端面を剥離型で切削するようにした
から、コイル筒の端面に第２図のように若干の高低のバ
ラツキがあつてもその凹凸は切削されて均一な面にする
ことができ、従つて、コイル長さがバラツクことがない
から、ダイナミックバランスを取り易く安定する。Since the end surface of the coil tube 1 is in contact with the rough surface of the peeling die 5, the insulation coating of the coil wire 6 is peeled off or the end surface is slightly cut. In this way, in the coil forming device of the present invention, the peripheral wall of the coil tube is held between the press mold and the core metal, and the end surface of the coil tube is cut with the peeling die. As shown in the figure, even if there is slight variation in height, the unevenness can be cut out to create a uniform surface.Therefore, since there is no variation in coil length, it is easy to maintain a dynamic balance and it is stable.
また、整流子板の導電部と電気的接続をするに際して、
逐一所定の箇所のコイル端面に位置するコイル素線の絶
縁皮膜を剥離する必要がないので結線を容易に行うこと
ができる効果がある。Also, when making electrical connections with the conductive parts of the commutator plate,
Since there is no need to peel off the insulation coating of the coil wire located on the coil end face at each predetermined location, there is an advantage that the wire connection can be easily performed.
