この発明は、長手方向が円弧状に延びる鞍型コイルの巻
線方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of winding a saddle-shaped coil whose longitudinal direction extends in an arc shape.

にコイルを巻線しなければならない場合がある。[Prior Art] For example, when trying to obtain a superconducting magnet using a superconducting wire, a winding technique is required to form a coil made of the superconducting wire. On the other hand, depending on the use of such a superconducting coil, it may be necessary to wind the coil in a saddle shape.

1上においてスライド可能に保持されている。The method of winding a saddle-shaped coil that extends linearly in the longitudinal direction is well established, and is carried out, for example, as shown in FIG. That is, a saddle-shaped winding frame 1 is prepared in order to give the coil a saddle-shaped shape. A winding core 2 is positioned on the winding frame 1 and fixed by suitable means. In this state, a wire 3 made of, for example, a superconducting material is wound around the winding core 2 along the winding core 2, and thereby,
A coil 4 is formed. At this time, in order to adjust the shape of the coil 4, the wire rod 3 is pressed from the outside as shown by an arrow 6 using a plurality of pushing jigs 5. The pushing jig 5 is slidably held on the winding frame 1 in order to adapt to the outer dimensions of the coil 4, which becomes thicker as the wire 3 is wound.
[発明が解決しようとする課題]
上述した巻線方法は、長手方向が直線状に延びる鞍型コ
イルを得るためのものである。したがって、この巻線方
法をそのまま適用したとしても、長手方向が円弧状に延
びる鞍型コイルを得ることはできない。[Problems to be Solved by the Invention] The above-described winding method is for obtaining a saddle-shaped coil that extends linearly in the longitudinal direction. Therefore, even if this winding method is applied as is, it is not possible to obtain a saddle-shaped coil whose longitudinal direction extends in an arc shape.

図に示した直線状の巻枠1に代えて、長手方向が円弧状
に延びる巻枠を用いればよい、と単純には考えられる。The arcuate saddle-shaped coil as described above is advantageously used, for example, in a bending magnet for a synchrotron. In order to obtain such a saddle-shaped coil having an arc shape, it is necessary to use a winding core whose longitudinal direction extends in an arc shape, and to
It is simply conceivable that instead of the linear winding frame 1 shown in the figure, a winding frame whose longitudinal direction extends in an arc shape may be used.

いながら、第7図に示したような押し込み治具5により
線材の側面から押えつけるだけで巻線を実施したとき、
線材が潰れたり、既に巻かれた線材を乗越えたりする。However, in order to align the wire rods 3 to form the coil 4 while pressing the wire rods 3 only from the sides with the pushing jig 5, the wire rods 3 must be aligned in a manner substantially similar to that shown in FIG. 3, relatively large rigidity is required, and for this reason, tape-shaped wire rods or keystone-type wire rods with a width of about 10 to 20 mm are generally used. For example, it is difficult to obtain an arcuate saddle-shaped coil by a method substantially similar to that shown in FIG. 7 using a thin wire with a diameter of about 1 mm. That is, when winding is carried out using such a thin wire by simply pressing the wire from the side with a pushing jig 5 as shown in FIG.
The wire may be crushed or it may run over already wound wire.
このことを、第8図を参照して説明する。This will be explained with reference to FIG.
第8図には、円弧状の巻芯2aの周囲に線材3aが巻か

巻芯2aから浮き上がらす方向の合成張力12が働き、
線材3aの整列状態がより乱れやすくなる。On the outer peripheral side of the winding core 2a, tensions as shown by arrows 7 and 8 act on the wire 3a, and their combined tension is represented by an arrow 9. On the other hand, on the inner peripheral side of the winding core 2a, tension as shown by arrows 10 and 11 acts on the wire 3a, and the combined tension is represented by an arrow 12. As can be seen from the direction of these composite tensions 9 and 12, especially on the inner peripheral side of the winding core 2a, the composite tension 12 acts in a direction that lifts the wire 3a from the winding core 2a,
The alignment of the wire rods 3a becomes more likely to become disordered.

を備える。[Means for Solving the Problems] As described above, the present invention is directed to a method of winding a saddle-shaped coil whose longitudinal direction extends in an arc shape. It is characterized by the following steps. In other words, a winding core whose longitudinal direction extends in an arc shape should be positioned on a saddle-shaped winding frame whose longitudinal direction extends in an arc shape so that their respective longitudinal directions are aligned, and the winding core should be wound around the core. The method includes steps of arranging a holding jig so as to face the winding frame to form a space for one layer of the wire, and winding the wire around the winding core in this state.

材が多層に巻かれる場合には、この空間は、押え治具と
既に巻かれた線材の層とによって形成される。Initially, the space for one layer of the wire to be wound around the core is formed by the holding jig and the winding frame, but when the wire is wound in multiple layers, this space is It is formed by a holding jig and a layer of already wound wire.
また、上述のように、線材が多層に巻かれる場合、既に
巻かれた線材の上に絶縁シートが配置されることが好ま
しい。Further, as described above, when the wire is wound in multiple layers, it is preferable that an insulating sheet is placed on the already wound wire.
この発明において、巻こうとすべき線材は、押え治具に
よって規制された線材の1層分の空間に受は入れられな
がら、巻芯の周囲に巻かれる。In this invention, the wire to be wound is wound around the winding core while being received in a space corresponding to one layer of the wire regulated by the holding jig.
[発明の効果]

囲において巻こうとすべき線材の1層分の空間しか形成

よって規制されながら、前記空間内において整列された
状態で、巻かれることができる。[Effects of the Invention] Therefore, according to the present invention, the presser jig forms only a space for one layer of the wire to be wound around the winding core, so that the wire rod to be wound around the winding core is It can be wound in an aligned state within the space while being regulated by the holding jig.

ことが可能になる。Note that when winding wire into multiple layers, the space for one layer of wire to be wound around the winding core is formed between the holding jig and the layer of wire that has already been wound. At this time, if an insulating sheet is placed on the already wound wire layer, it is possible to eliminate the unevenness formed on the surface of the already wound wire layer. Therefore, the friction between the layer of wire that has already been wound and the wire that is about to be wound is reduced, thereby enabling smooth winding work, and the insulation coating formed on the surface of the wire. No damage is caused and, moreover, it becomes possible to provide more complete insulation by the insulation sheet itself.

It is preferable to fix with an adhesive in order to prevent the aligned state from collapsing during subsequent handling. As the adhesive, quick-drying adhesives, self-fusing resins, etc. are advantageously used.

FIG. 2 shows an end view of a section taken along the line ■-■ in FIG. 1;
まず、長手方向が円弧状に延びる巻芯21が用意される

固定される。First, a winding core 21 whose longitudinal direction extends in an arc shape is prepared. Also, a saddle-shaped winding frame 2 whose longitudinal direction extends in an arc shape is also provided.
2 will be prepared. The center angle of the winding core 21 and the winding frame 22 with respect to the circular arc formed by each of them is selected to be about 90 degrees. The winding core 21 is positioned directly above the winding frame 22 so that their longitudinal directions are aligned. Although not shown, this positioning state is fixed by suitable fixing means.

いものが用いられる。To form the coil 20, a wire 23, such as a superconducting wire, is wound around the winding core 21. The superconducting wire used is preferably made of a flexible alloy, but superconducting wires made of other materials may also be used. Furthermore, a normal conducting wire may be used as the wire 23 instead of a superconducting wire. The wire 23 is thin and has a diameter of about 1 mm.
上述のように、線材23が巻芯21の周囲に巻かれると

る。また、押え治具25には、溝28が形成され、この
fj28内に巻芯21が受は入れられることによって、
押え治具25は巻芯21に対して位置決めされる。As described above, when the wire rod 23 is wound around the winding core 21, the holding jig 25 faces the winding frame 22 so as to form a space 24 for one layer of the wire rod 23 to be wound. It is arranged like this. As clearly shown in FIG. 2, the presser jig 25 has an inner circumferential surface 27 similar to the outer circumferential surface 26 of the winding frame 22, which has an arcuate cross section, and has a space 2 for one layer described above.
4 is formed between the outer circumferential surface 26 and the inner circumferential surface 27. In addition, a groove 28 is formed in the presser jig 25, and the winding core 21 is received in this fj28, so that
The presser jig 25 is positioned relative to the winding core 21.

整列状態で巻かれた線材23を備える鞍型コイル20が
得られる。このような線材23の整列状態を保持するた
め、線材23の巻回を終えた後、たとえば嫌気性かつ速
乾性の接着剤でその状態を固定してもよい。In this way, the wire 23 is rolled around the winding core 21 while being pushed into the space 24 corresponding to one layer with a relatively weak force. At this time, the movement of the wire rod 23 is restricted by the outer circumferential surface 26 of the winding frame 22 that defines the space 24 and the inner circumferential surface 25 of the presser jig 25, so the wire rod 23 rides on the already wound portion of the wire rod 23. I won't raise it. Therefore, a saddle-shaped coil 20 is obtained that includes wire rods 23 wound in a proper alignment state. In order to maintain such an aligned state of the wire rods 23, after winding of the wire rods 23 is completed, the condition may be fixed using, for example, an anaerobic and quick-drying adhesive.

ことが重要である。Instead of using a quick-drying adhesive as described above, the wire rod 23 is coated with a self-fusing resin in advance, and after being wound, the saddle-shaped coil 20 is heated to a temperature that allows self-fusing. The form may be fixed. When a superconducting wire is used as the wire 23, it is important to select the heating temperature within a range that does not deteriorate the performance of the superconducting wire.

コイル20が得られる。When the above steps are completed, the winding core 21 is removed from the presser jig 25 and the winding frame 22, and thereby the winding frame 2
A bipolar saddle-shaped coil 20 is obtained, which is composed of a wire rod 23 wound around the wire rod 2 and a wire rod 23 wound around the wire rod 23.
線材は、第3図に示すように、多層に巻くことも可能で
ある。第3図は、前述した第2図に相当する図である。The wire can also be wound in multiple layers as shown in FIG. FIG. 3 is a diagram corresponding to FIG. 2 described above.

を受は入れる溝28aを備える。After winding the first layer of the wire 23, the presser jig 25 shown in FIG. 2 is moved to another presser jig 25 as shown in FIG.
exchanged with a. The presser jig 25a includes an inner circumferential surface 27a having a smaller curvature, that is, a larger radius of curvature, than the inner circumferential surface 27 of the presser jig 25. A space 24a for one layer of the wire 23 to be wound is formed between the outer peripheral surface 29 and the inner peripheral surface 27a of the first layer of the wire 23. Further, like the presser jig 25, the presser jig 25a is similar to the presser jig 25.
The receiver is provided with a groove 28a into which the receiver is inserted.
このようにして、線材23の2層目の巻回が、巻芯21
の周囲であって、押え治具25mの内周面27aと1層

24a内において行なわれる。In this way, the second layer of the wire 23 is wound around the winding core 21.
This is carried out in a space 24a formed between the inner circumferential surface 27a of the holding jig 25m and the outer circumferential surface 29 of the first layer wire 23.
以後、さらに線材23の積層を繰返す場合には、各積層

れる。Thereafter, when stacking the wire 23 is repeated, the wire 23 is wound one layer at a time while being sequentially replaced with a holding jig having an inner circumferential surface having a curvature suitable for each stacking stage.
上述したように、巻回された線材23を多層化する場合

れた線材23の層の上に絶縁シート30を配置するのが
好ましい。As described above, when the wound wire 23 is multilayered, for example, as shown in FIG.
Since the outer periphery 29 of the wire 3 is uneven, a relatively large friction occurs between the wire 23 and the wire 23 about to be wound, which may cause damage to the insulation coating of the wire 23. To solve this problem, it is preferable to place an insulating sheet 30 on top of the already wound layer of wire 23, as shown in FIG.
第4図には、押え治具25bを用いて、3層目の線材2
3を巻いている途中の状態が示されている。第4図にお

番号を付し、重複する説明は省略する。In FIG. 4, the third layer wire 2 is
3 is shown in the middle of being wound. In FIG. 4, parts corresponding to those shown in FIG. 2 are given the same reference numerals, and redundant explanations will be omitted.

芯21の周囲に巻こうとすべき線材23の1層分の空間
24bは、絶縁シート30と押え治具25bの内周面2
7bとの間に形成される。As shown in FIG. 4, when the insulating sheet 30 is used, the space 24b for one layer of the wire 23 to be wound around the winding core 21 is the inner peripheral surface of the insulating sheet 30 and the holding jig 25b. 2

3の巻線作業をより円滑なものとするとともに、絶縁シ
ート30自身が与える絶縁によって、線材23の各部分
間の絶縁をより完全なものとすることができる。Therefore, the presence of the insulating sheet 30 not only reduces damage to the insulation coating of the wire 23 but also
In addition to making the winding work of No. 3 smoother, the insulation provided by the insulating sheet 30 itself makes it possible to more completely insulate each part of the wire 23.

A winding core 33 whose longitudinal direction extends in an arc shape is positioned at a position shifted by 45 degrees from directly above the winding core 2 . At this time, the winding core 3
