も用いられている。2. Description of the Related Art Conventionally, some manufacturing methods are currently used for manufacturing bushing base plates. In general, a method of manufacturing a bushing base plate by making a hole in a blank plate of the bushing base plate, inserting a pipe-shaped chip in advance into the hole, and joining them by welding is widely used. There is also a method of manufacturing a bushing base plate by compressing a material thicker than the product size with a roll or a press, extruding the protrusions, and then punching the extruded protrusions with a press. It is used.

シングベースプレートの製造方法は次のような問題点が
ある。The method of manufacturing the bushing base plate described above has the following problems.

なわれている。First, when the bushing base plate base plate is perforated and a pipe-shaped tip is inserted into the hole and welded, as shown in FIG. 1, the bushing base plate base plate 1 and the discharge hole 2 are formed. The pipe-shaped tip 3 constituting the above is welded at the base end portion 3a of the tip 3 by laser, plasma or the like, or resistance welding is performed.

Was thin because of the spinning conditions of glass fiber. When joining the base plate 1 of the bushing base plate to a pre-drilled portion, the base end portion 3a of the tip 3 in FIG. 1, that is, the glass inlet side is welded.

法が取られている。In the case of welding, the entire thickness of the base plate 1 of the bushing base plate is melted because the thickness of the tip 3 is smaller than the thickness of the base plate 1 of the bushing base plate and the diameter of the discharge hole 2 is small. Since it is difficult to do so, a method of welding a part of the upper layer portion of the base plate 1 as shown in FIG. 1 is adopted.

く全体がふくらみをもつように張り出し状に変形する。When the bushing base plate 4 manufactured as described above is used at a high temperature for a long time, the bushing base plate 4 receives the pressure P of the glass 5 to cause creep strain, and the bushing base plate 4 is entirely deformed as shown in FIG. Deforms into an overhanging shape with a bulge.

又ひどいケースはこのチップ３が抜けおちてしまう場合
も生じている。FIG. 3 is an enlarged view of the mounting portion of the tip 3. When the base plate 1 of the bushing base plate undergoes creep deformation, a gap is formed between the tip 3 and the tip 3, and a crack 6 is formed in the upper welding part. As a result, there is a problem that the glass liquid leaks and the glass fiber cannot be spun.
In a terrible case, the chip 3 may fall out.

起こりにくい成形をするかが問題である。The problem is that, in the glass fiber manufacturing process, expensive Pt-alloy bushings all become unusable due to cracking or falling off of only one discharge hole, and production must be stopped. Therefore, it is a fatal defect and has a great influence on the quality and cost of glass fiber. The problem is how to make the molding so strong that cracks and falling are unlikely to occur.

After that, a circular or irregularly shaped projection having the required number of holes is formed.
The inner diameter of the tubular protrusion is larger than the diameter of the product discharge hole, and its shape is provided with an opening such as a taper or a step to finish the shape in accordance with the joining of the hollow tubular objects.

Compared with the one with welded ends, the bushing base plate has a tubular projection for reinforcement on the base plate, and the inside of the hole is tapered or stepped when the tubular projection is molded. Since it is possible to finish processing, it is possible to stably join hollow tubular objects, and even if it is used at high temperature for a long time, even if the base plate of the bushing base plate is deformed, a hole will open at the tubular projection Does not occur at all, so the welded part is not subject to a tensile stress, so the welded part does not crack or leaks and the life is extended (30%).

A hollow tubular article 11 having a dimension and shape shown in FIG. 8 and made of an h10% -Au5% alloy was press-fitted, resistance-welded as shown in FIG. 9, and then heat-treated at 1400 ° C. for 20 hours, whereby the tubular projection 10 was heated. The entire surface of the press-fitted hollow tubular article 11 was made to bond by thermal diffusion. The bushing base plate 13 thus completed was arc-welded to the electrode portion and the side wall portion to form a bushing. The reason for adding 5% Au is to improve the wettability during spinning and to enhance the thermal diffusion property.
