Conventionally, as shown in Fig. 1, a corrugated sheet 1, which is a cooling device for an oil-filled transformer tank, is formed continuously from top to bottom, and the corrugated sheet 1 is processed in advance to fit the shape of the four corners. An oil-filled tank was manufactured by forming an R-formed corrugated plate 2 into which the R-formed corrugated plate 2 was formed, and then as shown in Fig. 2, an R-formed flange 3 whose corners were R-formed, and an R-formed bottom plate 4 were assembled and joined vertically. . Also, even in the case of an octagonal shape with sides at the four corners as shown in Fig. 3, it is possible to
The corrugated plate 1 is subjected to a continuous bending process A from top to bottom as shown in FIG. 4 to form an octagonal corrugated plate 7, and in combination with the octagonal flange 5 and the octagonal bottom plate 8, an oil-filled tank can be manufactured. However, both the R-shaped corrugated sheet 2 and the octagonal corrugated sheet 7 require processing of the corrugated sheet 1 using special equipment, which takes a lot of man-hours. Furthermore, the shape after molding is unstable, making it difficult to store and requiring a large amount of space. On the other hand, the area to be formed is limited to the bottom portion of the corrugated sheet 1, and in order to match the flanges 3, 5 and the bottom plates 4, 8, it is necessary to limit the variation in the dimensions of the corrugated sheet. In other words, if the dimensions of the R-shaped or octagonally shaped corrugated plates 2 and 7 are larger than the flanges and the bottom plate, when combined with the flanges 3 and 5 and the bottom plates 4 and 8, the gap becomes large and welding becomes difficult. On the other hand, if it becomes too small, it becomes impossible to assemble it.

要とするという問題がある。 A related device of this type is, for example, Japanese Patent Application Laid-Open No. 55-98808, which describes a method in which the corrugated plates (heat dissipation ribs) are formed into a rectangular cylindrical shape before being fixed to the upper and lower frames. This requires the same number of processing steps as in the prior art described above, and there is a problem in that it is difficult to store the cylindrical corrugated plate and a large amount of space is required.

The present invention is a method in which the corrugated sheet 1 is not processed in advance, but is simply fitted to predetermined locations on the flange 5 and the bottom plate 8, and is continuously formed and assembled at the same time. Therefore, the only processed parts of the corrugated plate 1 are the flange 5 and the area of a few millimeters that are wrapped around the bottom plate 8, and no other processing has been added to the other parts.

Embodiments of the present invention will be described below with reference to FIGS. 5 to 10. The process up to fixing the corrugated plate to the upper and lower frames will be explained with reference to FIGS. 51, 52, and 53. preset flange 5 (upper frame),
The upper and lower ends of the corrugated plate 1 are attached to the flanges 5 so as to wrap by the required dimension W on the bottom plate 8 (lower frame body).
The corrugated sheet 1 is carried in along the bottom plate 8. This state is shown in FIG. After loading, the lap parts of the flange 5, bottom plate 8 and corrugated sheet 1 are temporarily fixed by welding, and then the corrugated sheet 1 is pulled in and rotated in the direction of the arrow as shown in FIG. This is done by applying pressure to the corrugated sheet 1 from above as shown by the arrow and temporarily fixing it by welding. After temporary fixing, the joints are welded and fixed in a liquid-tight manner. The process is then repeated for the number of sides to assemble the tank. Figure 8 shows the completed tank. Therefore, even if there is a gap in the corrugated plate 1 at the corner of the side as shown in Fig. 6, or even if the bottom of the wave crest is located at the corner as shown in Fig. 7, it will not hinder assembly. As long as the overall dimensions of the corrugated sheet 1 are maintained, the dimensions of the sides are free. Further, as shown in Fig. 9, the lengths of the four corners of one tank can be made to any desired length.

なる。 As shown in FIG. 10, the required number of sides can be provided at the four corners only when necessary. In the tank assembled using the above method, only the upper and lower ends of the corrugated plates and the joints with the frame are molded to fit the frame, and the rest of the center part is not processed.
Even in the case of a polygonal tank, the corners will be curved.

The present invention uses the upper and lower frames as molds and deforms the corrugated sheet along these molds to create a tank, so there is no need for the process of bending the corrugated sheet in advance, making it possible to eliminate the need for a mold, which is economical. In addition, it can accommodate any shape of the upper and lower frames, making it suitable for high-mix, low-volume production.Furthermore, an integrated line from the corrugated sheet production line to tank assembly can be easily established, eliminating the need for a storage area for the corrugated sheets and simplifying the manufacturing process. It is possible to save space. In addition, since the joint portion of the corrugated plate with the frame is molded to fit the frame, the corrugated plate can be fixed liquid-tightly along the corners of the upper and lower frames, improving the reliability of the tank. Since there is no need to process narrow waves as in the past, there is no need to damage the waves or check dimensions. Furthermore, since the number of sides and the type of sides can be set arbitrarily, the corrugated plate used as the cooling device can be freely processed and an optimal design can be achieved.
