Ultra-thin wires such as molybdenum and tungsten that expand and contract due to temperature differences during the warm season tend to unravel when wound many times, and are also disadvantageous in terms of losses due to unrolled wires and pollution caused when discarded. In addition, when manufacturing metal products, the upper and lower plates, flange, etc. were made separately and assembled, which not only required a large number of attachments, but also required a long manufacturing process and a large amount of manpower. It was low.
本発明は以上の点を鑑みて発明されたもので、一枚のア

5 (see Fig. 9), turn the main body upside down and fit a circular reinforcing plate 11 with a central hole 10 in the center into the caulking part 3,
The reinforcing plate 11 is fixed by caulking the caulking part 3 with the round holes c for positioning passed through the through holes 9 and 10 (10th
(see Figure and Figure 1130).
７ 最後に、鍔と胴部との交点を削り両者の成す角を正

のではない。In addition, as another method for forming the bulging portion 3 in the above manufacturing process 3, a vacuum device may be attached to the top surface of the main body and while suction is being applied, the rising portion 4 may be drawn inward using a split die b. Further, the reinforcing plate 11 in Step 6 does not need to be made of the same amount of material as the main body, and is not limited to the above embodiment.

効果を奏する。The spool according to the present invention is made of metal such as aluminum and does not expand or contract due to temperature differences, so there is no need to worry about the ultra-fine wire of tungsten, molybdenum, etc.
It does not break even if dropped and is lightweight, making it easy to transport.Conventional products, as shown in Figure 1, have many assembled parts, requiring a large amount of material and requiring a long process. but,
Since the product of the present invention is produced by sequential drawing from a single circular plate, not only the amount of material is small, but the process is short and it is very advantageous in terms of labor and production costs. In addition, in order to accurately wind ultra-fine wire such as tungsten or molybdenum onto a spool, or to prevent the winding from collapsing after winding,
Although it is necessary to prevent waves from hitting the body part 6, the intersection between the body part 6 and the collar 8 becoming a curved surface, and the through holes 9 and 10 being shifted from the center, the present invention is suitable for step 3. In this step, the body part 6 is formed at the same time as the bulging part 5 is formed on the upper part of the main body, and the bulging part 5 is crushed in two stages in the next step 4 and step 5, so manufacturing is easy. Not only that, but the precision of the product is extremely high.
When fixing, the caulking part 3 is caulked with the round rod c for positioning passed through the through holes 9, 10, so the through holes 9, 10
has various effects such as being able to be positioned accurately on the center line.
