本発明は、変圧器に用いる箔状コイルの製造装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to an apparatus for manufacturing a foil coil used in a transformer.
（従来の技術）
金属シートと絶縁シートとを重ねて巻回して成る箔状コ
イルは、巻線の占積率が良く、小型軽量化できる特徴を
有している。すでに、数ＫＶ、数１００ＫＶ程度の比較
的電圧の低い小容量のコイルではすでに実用化されてい

器のコイルへの適用拡大が研究されている。(Prior Art) A foil-like coil formed by overlapping and winding a metal sheet and an insulating sheet has a good winding space factor and is characterized by being small and lightweight. It has already been put into practical use in small capacity coils with relatively low voltages of several KV or several hundred KV, but in recent years, in view of its excellent advantages, research has been conducted to expand its application to coils with higher voltages and larger containers. has been done.

れぞれ口出し４が取付けられている。The structure of a conventional foil coil is shown in FIG. In FIG. 3, a metal sheet 1 and an insulating sheet 2 are wound around a basic insulating cylinder 3 to form a foil-like coil, and the inner and outer ends of the foil-like coil are separated. An opening 4 is attached to each metal sheet 1.

、異種金属の接合法としては従来より金型による冷間圧
接方法が知られている。In such a foil coil, since the conductor is the metal sheet 1, it is necessary to join the metal sheet 1 and the opening 4. In a configuration in which the metal sheet 1 is made of a metal that can be made lightweight, such as aluminum, and the lead metal is made of a metal that has good conductivity and can be made compact, such as copper, the overall weight of the coil can be reduced, and the lead metal can be made lighter. It has been widely adopted because it has a smaller part and provides a coil with excellent insulation strength, but since it is made of different metals, a bonding process is required. In this case, as a method for joining dissimilar metals, a cold pressure welding method using a mold is conventionally known.
第４図に、この様な冷間圧接方法を用いた公知の箔状コ
イルの製造方法を示す。FIG. 4 shows a known method for manufacturing a foil coil using such a cold pressure welding method.

箔状コイルの製造方法の原理図を描いたもので、巻型の
駆動装置やフレーム等は省略しである。First, when manufacturing the foil coil 9, the guide roller 6
The metal sheet 1 pulled out by the cold welding device 10
Join it with the opening 4. Then, it is attached together with the insulating sheet 2 to the basic insulating tube 3 which has been attached to the winding form 5 in advance, and winding is started. The winding ends when the set dimension is reached.
After cutting the metal sheet 1, the end portion of the metal sheet 1 is inserted into a cold pressure welding device 10 consisting of a pressure welding frame 7 and a mold 8,
Joining with the opening 4 is performed using a mold 8. In addition, Figure 4 shows
This is a diagram depicting the principle of the method for manufacturing foil coils, and the winding former drive device, frame, etc. are omitted.
ところで、以上の様な製造装置と冷間圧接装置とを使用
した箔状コイルの製造方法において、金属シートの幅が
狭く、口出しも小型の小容量の箔状コイル９を製造する
場合には、口出し４を金属シート１に接合した俊、手作
業により容易にｉｌｌ絶縁筒３にセットすることが可能
である。By the way, in the method of manufacturing a foil coil using the manufacturing apparatus and cold pressure welding apparatus as described above, when manufacturing a small capacity foil coil 9 with a narrow metal sheet and a small opening, Since the opening 4 is bonded to the metal sheet 1, it can be easily set in the ill insulating tube 3 by hand.
しかしながら、大容量の箔状コイル９を製造する場合に
は、金属シート１の幅が広く、また、口出し４も大型と
成るため、冷間圧接装置で口出し４を接合した後、手作
業により基礎絶縁筒４にセットすることが困難である。However, when manufacturing a large-capacity foil coil 9, the width of the metal sheet 1 is wide and the opening 4 is also large. It is difficult to set it in the insulating tube 4.
更に、この様に口出しが大型の場合、口出しと金属シー
ト幅全体との接合を一度に行おうとすると非常に大型の
金型を使用しなければならないため、小型の金型８を使

ート１の幅方向に移動可能に構成し、多数回に渡って接
合を行う方法が要求される。Furthermore, when the opening is large like this, a very large mold must be used to join the opening and the entire width of the metal sheet at once, so a small mold 8 is used. A method is required in which the press welding frame 7 of the cold press welding apparatus 10 is configured to be movable in the width direction of the metal sheets 1 and the welding is performed multiple times.
また、金属シート１が比較的厚い場合は、口出しも比例
して大型になるため、作業性が著しく悪くなる。一方、
金属シート１が比較的薄い場合は、作業中に金属シート
１にしわが発生し易くなる。Furthermore, if the metal sheet 1 is relatively thick, the opening will also be proportionally large, resulting in significantly poor workability. on the other hand,
When the metal sheet 1 is relatively thin, wrinkles are likely to occur in the metal sheet 1 during operation.
このしわは、箔状コイル９の機械特性や、絶縁特性を悪

金属シート１を一旦切断するか、または大きく弛ませる
がしなければならず、作業性の低下し、また、弛ませた
場合には巻取ったコイルが緩み、機械的強度が著しく低
下してしまう。These wrinkles cause deterioration of the mechanical properties and insulation properties of the foil coil 9. In addition, in the case of a large-capacity foil coil 9, an opening 4 may be required at an intermediate position of the coil in addition to the winding start and winding end.In this case, if a device as shown in FIG. In order to join the lead during winding, the metal sheet 1 must be cut or loosened to a large extent, which reduces work efficiency and also causes the wound coil to become loose. , the mechanical strength will be significantly reduced.
