Description

本開示は、剥離装置に関し、例えば、平角線における導体を被覆する絶縁材を剥離するための装置に関する。 The present disclosure relates to a stripping device, for example, a device for stripping an insulating material covering a conductor in a flat wire.

図７に示すように、モータに用いられる平角線１０１は、導体１０２を絶縁材（エナメル）１０３によって被覆した構成であるが、平角線１０１の端部などは、端部同士を接合するために絶縁材１０３が剥離される。 As shown in FIG. 7, the flat wire 101 used in the motor has a configuration in which the conductor 102 is covered with an insulating material (enamel) 103, but the ends of the flat wire 101 and the like are for joining the ends to each other. The insulating material 103 is peeled off.

このとき、例えば、所謂エナメルメクレが生じないように、図７に示すように、平角線１０１の横断方向に仮切込加工刃１０４を移動させて、絶縁材１０３に仮切込１０５を形成し、その後、図８に示すように、平角線１０１の横断方向に剥離刃を移動させて絶縁材１０３を剥離している。 At this time, for example, as shown in FIG. 7, the temporary cutting blade 104 is moved in the transverse direction of the flat wire 101 to form the temporary cutting 105 in the insulating material 103 so that the so-called enamel meshle does not occur. After that, as shown in FIG. 8, the peeling blade is moved in the transverse direction of the flat wire 101 to peel the insulating material 103.

ちなみに、特許文献１の剥離装置は、第１の切削部材を旋回させて平角線の上面側の絶縁材を剥離した後に、第２の切削部材を旋回させて平角線の下面側の絶縁材を剥離している。 Incidentally, in the peeling device of Patent Document 1, after the first cutting member is swiveled to peel off the insulating material on the upper surface side of the flat wire, the second cutting member is swiveled to peel the insulating material on the lower surface side of the flat wire. It is peeling off.

本出願人は、以下の課題を見出した。上述のように所謂エナメルメクレが生じないように仮切込１０５を形成しているが、平角線１０１の送りのバラツキによって、図８に示すようにエナメル残り１０６が発生する。一方、平角線の送りのバラツキによる影響を抑制するために、仮切込加工と剥離加工とを略同時に行う場合、仮切込加工刃の後退時に当該仮切込加工刃が絶縁材の端部に強く接触して所謂エナメルメクレが生じる。 The applicant has found the following issues. As described above, the temporary cut 105 is formed so that the so-called enamel meshle does not occur, but due to the variation in the feed of the flat wire 101, the remaining enamel 106 is generated as shown in FIG. On the other hand, when the temporary cutting process and the peeling process are performed substantially at the same time in order to suppress the influence of the variation in the feed of the flat wire, the temporary cutting process blade is at the end of the insulating material when the temporary cutting process blade is retracted. The so-called enamel blade is generated by strong contact with the blade.

本開示は、このような問題点に鑑みてなされたものであり、エナメル残りや所謂エナメルメクレの発生を抑制可能な剥離装置を実現する。 The present disclosure has been made in view of such problems, and realizes a peeling device capable of suppressing the generation of enamel residue and so-called enamel mekure.

平角線における導体を被覆する絶縁材を剥離するための装置であって、
前記平角線の長手方向に対して直交する横断方向に進退可能な一対の仮切込加工刃と、
前記一対の仮切込加工刃と一体になって前記平角線の横断方向に進退可能であって、前記一対の仮切込加工刃によって前記平角線に形成された仮切込の間の前記絶縁材を剥離する剥離刃と、
を備え、
前記仮切込加工刃は、当該仮切込加工刃の前進側の部分に形成され、且つ、前記仮切込加工刃の前進側に向かって細くなる第１のテーパー部と、前記仮切込加工刃の後進側の部分に形成され、且つ、前記仮切込加工刃の後進側に向かって細くなる第２のテーパー部と、を有する。
このように仮切込加工刃が第１のテーパー部及び第２のテーパー部を備えているので、所謂エナメルメクレの発生を抑制することができる。しかも、仮切込加工刃と剥離刃とが一体的に進退するので、エナメル残りの発生を抑制することができる。そのため、上述の剥離装置は、エネメル残りや所謂エナメルメクレの発生を抑制しつつ、絶縁材を剥離することができる。 The peeling device according to one aspect of the present disclosure is
A device for peeling off the insulating material that covers a conductor in a flat wire.

Moreover, since the temporary cutting blade and the peeling blade move forward and backward integrally, it is possible to suppress the generation of enamel residue. Therefore, the above-mentioned peeling device can peel off the insulating material while suppressing the generation of enamel residue and so-called enamel mekure.

本開示によれば、エナメル残りや所謂エナメルメクレの発生を抑制可能な剥離装置を実現できる。 According to the present disclosure, it is possible to realize a peeling device capable of suppressing the generation of enamel residue and so-called enamel mekure.

このような第１の剥離部４の治具４１と第２の剥離部５の治具５１とは、図１に示すように、Ｚ軸方向に重ねた状態でボルト８を介して固定されている。このとき、第１の剥離部４の治具４１のＺ軸＋側であって、且つ、Ｘ軸＋側の部分に形成された第３の切り欠き部４１ｄと、第２の剥離部５のＺ軸－側であって、且つ、Ｘ軸＋側の部分に形成された第３の切り欠き部５１ｄと、によって、平角線１０１が挿入される被挿入部９が形成されている。被挿入部９のＺ軸方向の高さは、平角線１０１の導体１０２の厚さと略等しい。 As shown in FIG. 1, the jig 41 of the first peeling portion 4 and the jig 51 of the second peeling portion 5 are fixed to each other via bolts 8 in a state of being overlapped in the Z-axis direction. There is. At this time, the third cutout portion 41d formed on the Z-axis + side and the X-axis + side portion of the jig 41 of the first peeling portion 4 and the second peeling portion 5 A third notch 51d formed on the Z-axis-side and the X-axis + side portion forms a inserted portion 9 into which the flat wire 101 is inserted. The height of the inserted portion 9 in the Z-axis direction is substantially equal to the thickness of the conductor 102 of the flat wire 101.

次に、本実施の形態の剥離装置１を用いて平角線１０１の絶縁材１０３を剥離する流れを説明する。先ず、剥離装置１をＸ軸＋側に前進させて、第１の仮切込加工部２の第１の仮切込加工刃２２及び第２の仮切込加工刃２３で平角線１０１の絶縁材１０３におけるＺ軸－側の部分に仮切込１０５を形成すると共に、第２の仮切込加工部３の第１の仮切込加工刃３２及び第２の仮切込加工刃３３で平角線１０１の絶縁材１０３におけるＺ軸＋側の部分に仮切込１０５を形成する。 Next, a flow of peeling the insulating material 103 of the flat wire 101 using the peeling device 1 of the present embodiment will be described. First, the peeling device 1 is advanced to the X-axis + side, and the flat wire 101 is insulated by the first temporary cutting blade 22 and the second temporary cutting blade 23 of the first temporary cutting portion 2. A temporary cut 105 is formed in the portion on the Z-axis-side of the material 103, and the first temporary cut blade 32 and the second temporary cut blade 33 of the second temporary cut portion 3 form a flat angle. A temporary cut 105 is formed in the portion on the Z-axis + side of the insulating material 103 of the wire 101.

このとき、各々の仮切込加工刃２２、２３、３２、３３の第１のテーパー部は、Ｘ軸＋側に向かってＹ軸方向の幅寸法が細くなる形状に形成されているので、剥離装置１が前進するのに従って、絶縁材１０３を切り開いて塑性変形させるように仮切込１０５を形成する。そのため、所謂エナメルメクレが発生することを抑制できる。 At this time, since the first tapered portion of each of the temporary cutting blades 22, 23, 32, 33 is formed in a shape in which the width dimension in the Y-axis direction becomes narrower toward the X-axis + side, it is peeled off. As the device 1 advances, the insulating material 103 is cut open to form a temporary cut 105 so as to be plastically deformed. Therefore, it is possible to suppress the occurrence of so-called enamel mekure.

そして、剥離装置１をさらに前進させて、平角線１０１における仮切込１０５の間の絶縁材１０３を第１の剥離部４の剥離刃４２及び第２の剥離部５の剥離刃５２によって剥離する。このとき、平角線１０１は送っておらず、移動していないので、エナメル残りの発生を抑制することができる。 Then, the peeling device 1 is further advanced to peel the insulating material 103 between the temporary cuts 105 in the flat wire 101 by the peeling blade 42 of the first peeling portion 4 and the peeling blade 52 of the second peeling portion 5. .. At this time, since the flat wire 101 has not been sent and has not moved, it is possible to suppress the generation of enamel residue.

しかも、第１の仮切込加工刃２２、３２の第１のテーパー部のＹ軸＋側の面は、絶縁材１０３をＹ軸＋側に押し込み、第２の仮切込加工刃２３、３３の第１のテーパー部のＹ軸－側の面は、絶縁材１０３をＹ軸－側に押し込んでいる。 Moreover, the Y-axis + side surface of the first tapered portion of the first temporary cutting blades 22 and 32 pushes the insulating material 103 toward the Y-axis + side, and the second temporary cutting blades 23 and 33. The Y-axis-side surface of the first tapered portion pushes the insulating material 103 toward the Y-axis-side.

そして、Ｙ軸＋側の仮切込１０５のＹ軸＋側の端部とＹ軸－側の仮切込１０５のＹ軸－側の端部との間隔に対して第１の剥離部４の剥離刃４２及び第２の剥離部５の剥離刃５２のＹ軸方向の長さは、若干、短い。 Then, with respect to the distance between the Y-axis + side end of the Y-axis + side temporary cut 105 and the Y-axis-side end of the Y-axis-side temporary cut 105, the first peeling portion 4 is used. The length of the peeling blade 42 and the peeling blade 52 of the second peeling portion 5 in the Y-axis direction is slightly short.

そのため、仮切込１０５の間の絶縁材１０３を剥離刃４２、剥離刃５２によって剥離する際に、Ｙ軸＋側の仮切込１０５に対してＹ軸＋側に配置される絶縁材１０３及びＹ軸－側の仮切込１０５に対してＹ軸－側に配置される絶縁材１０３の端面に剥離刃４２、５２が接触することを抑制できる。これにより、所謂エナメルメクレの発生を抑制することができる。 Therefore, when the insulating material 103 between the temporary cuts 105 is peeled off by the peeling blade 42 and the peeling blade 52, the insulating material 103 arranged on the Y-axis + side with respect to the temporary cut 105 on the Y-axis + side and It is possible to prevent the peeling blades 42 and 52 from coming into contact with the end face of the insulating material 103 arranged on the Y-axis-side with respect to the temporary notch 105 on the Y-axis-side. This makes it possible to suppress the generation of so-called enamel mekure.

次に、剥離装置１をＸ軸－側に後退させて、平角線１０１における絶縁材１０３が剥離された領域に第１の剥離部４の剥離刃４２及び第２の剥離部５の剥離刃５２を通す。このときも、剥離刃４２、５２で絶縁材１０３を剥離する際と同様に、Ｙ軸＋側の仮切込１０５に対してＹ軸＋側に配置される絶縁材１０３及びＹ軸－側の仮切込１０５に対してＹ軸－側に配置される絶縁材１０３の端面に剥離刃４２、５２が接触することを抑制でき、その結果、所謂エナメルメクレの発生を抑制することができる。 Next, the peeling device 1 is retracted to the X-axis-side, and the peeling blade 42 of the first peeling portion 4 and the peeling blade 52 of the second peeling portion 5 are formed in the region where the insulating material 103 is peeled off in the flat wire 101. Through. At this time as well, as in the case of peeling the insulating material 103 with the peeling blades 42 and 52, the insulating material 103 and the Y-axis-side arranged on the Y-axis + side with respect to the temporary cut 105 on the Y-axis + side. It is possible to suppress the peeling blades 42 and 52 from coming into contact with the end faces of the insulating material 103 arranged on the Y-axis-side with respect to the temporary cut 105, and as a result, it is possible to suppress the generation of so-called enamel meshle.

そして、剥離装置１をさらに後進させて、平角線１０１における絶縁材１０３が剥離された領域に第１の仮切込加工部２の第１の仮切込加工刃２２及び第２の仮切込加工刃２３を通すと共に、第２の仮切込加工部３の第１の仮切込加工刃３２及び第２の仮切込加工刃３３を通す。 Then, the peeling device 1 is further moved backward, and the first temporary cutting blade 22 and the second temporary cutting of the first temporary cutting section 2 are made in the region where the insulating material 103 is peeled off in the flat wire 101. Along with passing the processing blade 23, the first temporary cutting processing blade 32 and the second temporary cutting processing blade 33 of the second temporary cutting processing unit 3 are passed.

このとき、各々の仮切込加工刃２２、２３、３２、３３の第２のテーパー部は、Ｘ軸－側に向かってＹ軸方向の幅寸法が細くなる形状に形成されている。そのため、剥離装置１が後進する際に、第１の仮切込加工刃２２、３２の第２のテーパー部のＹ軸＋側の面がＹ軸＋側の仮切込１０５に対してＹ軸＋側に配置される絶縁材１０３の端面にスムーズに接触し、また、第２の仮切込加工刃２３、３３の第２のテーパー部のＹ軸－側の面がＹ軸－側の仮切込１０５に対してＹ軸－側に配置される絶縁材１０３の端面にスムーズに接触する。 At this time, the second tapered portion of each of the temporary cutting blades 22, 23, 32, 33 is formed in a shape in which the width dimension in the Y-axis direction becomes narrower toward the X-axis − side. Therefore, when the peeling device 1 moves backward, the Y-axis + side surface of the second tapered portion of the first temporary cutting blades 22 and 32 is the Y-axis with respect to the Y-axis + side temporary cutting 105. The end surface of the insulating material 103 arranged on the + side is smoothly contacted, and the Y-axis-side surface of the second tapered portion of the second temporary cutting blades 23 and 33 is the Y-axis-side temporary surface. Smoothly contacts the end face of the insulating material 103 arranged on the Y-axis-side with respect to the notch 105.

これにより、各々の仮切込加工刃２２、２３、３２、３３が平角線１０１の絶縁材１０３に引っ掛かることなく、所謂エナメルメクレの発生を抑制することができる。 As a result, the temporary cutting blades 22, 23, 32, 33 do not get caught in the insulating material 103 of the flat wire 101, and the generation of so-called enamel meshle can be suppressed.

このように本実施の形態の剥離装置１において、各々の仮切込加工刃２２、２３、３２、３３が第１のテーパー部及び第２のテーパー部を備えているので、所謂エナメルメクレの発生を抑制することができる。 As described above, in the peeling device 1 of the present embodiment, since each of the temporary cutting blades 22, 23, 32, 33 has a first tapered portion and a second tapered portion, so-called enamel meshle is generated. Can be suppressed.

しかも、本実施の形態の剥離装置１は、第１の仮切込加工部２、第２の仮切込加工部３、第１の剥離部４及び第２の剥離部５が一体的な構成であり、平角線１０１に仮切込１０５を形成した後に当該平角線１０１を送らずに絶縁材１０３を剥離する構成である。そのため、エナメル残りの発生を抑制することができる。 Moreover, in the peeling device 1 of the present embodiment, the first temporary cutting processing portion 2, the second temporary cutting processing portion 3, the first peeling portion 4, and the second peeling portion 5 are integrally configured. This is a configuration in which the insulating material 103 is peeled off without sending the flat wire 101 after forming the temporary cut 105 in the flat wire 101. Therefore, it is possible to suppress the generation of residual enamel.

したがって、本実施の形態の剥離装置１は、エネメル残りや所謂エナメルメクレの発生を抑制しつつ、絶縁材１０３を剥離することができる。 Therefore, the peeling device 1 of the present embodiment can peel the insulating material 103 while suppressing the generation of enamel residue and so-called enamel mekure.
