Description of the Related Art Conventionally, in order to manufacture a bushing base plate, first, as shown in FIG. 7, a bushing base plate material 1 is placed on a die 3 having a large number of chip holes 2 at regular intervals and is pressed by a forging hammer 4. Or by rolling with a roll 5 to push a part of the bushing base plate material into the chip hole 2 of the template 3 by plastic deformation to form a projection 6 and to form the bushing base plate material 1
The portion other than the protrusion 6 is thinned. After that, every time the mold 3 and the bushing base plate material 1 are intermittently advanced by a certain size, the plastic working is performed to form the projection 6 on the entire surface of the bushing base plate material 1 and thin the entire portion other than the projection 6. Then, as shown in FIG. 8, a punch and a reamer 7 were driven into the protrusion 6 of the bushing base plate material 1 from the back side of the protrusion 6, and a nozzle hole 8 was bored to form a protrusion nozzle 9 to form a bushing base plate 10.

Therefore, when the glass fiber is discharged and spun by such a projection nozzle 9, the quality is deteriorated by cutting in the middle or variation in thickness.

Since it remains when it is drilled, when it is exposed to a high temperature state of glass melting, cracks occur and the life is remarkably reduced.

Therefore, when electricity is applied as the heating element, the temperature distribution is not uniform, so that there is a difference in the viscosity of the molten glass discharged from each projection nozzle 9, resulting in uneven quality of the obtained glass fiber or the like.

出来る。As described above, in the method of manufacturing the bushing base plate of the present invention, the bushing base plate material having the finished thickness dimension obtained by rolling can be used, and many protrusions can be pressed at high speed, and the plate Since the plastic deformation is small and the deformation is concentrated only on the place where the projection is to be formed, the dimensional accuracy of the bushing base plate can be maintained high. Further, since the cutting stress in the lateral direction as described above does not occur at the root of the protruding portion, cracking does not occur in the process of drilling. The required volume of the protrusion nozzle can be adjusted by the individual pieces, and it is also possible to select the individual dimension according to the height and shape of the protrusion nozzle. In addition, when making individual pieces, since a long one is automatically formed by a wire or a strip, a uniform volume can be obtained.

In particular, the life can be extended by covering the glass containing Au and the bushing base plate material with a material having a role of a barrier for preventing the diffusion of Au.
The bushing base plate of the invention is a production method that is flat in plate thickness and highly uniform, and is uniform without protrusion nozzle volume, dimensional accuracy, and eccentricity, and suitable for mass production.
In addition, it is a stable manufacturing method with less yarn breakage during spinning.

来る。As can be seen from the above description, according to the method for manufacturing a bushing base plate of the present invention, a projection nozzle capable of producing a glass fiber or the like having a high dimensional accuracy and a uniform quality can have a uniform wall thickness. It has an excellent effect that a shearing stress does not remain at the root of the nozzle, it does not crack at high temperature, and a flat bushing base plate having a uniform thickness can be manufactured. Further, according to the method for manufacturing the bushing base plate of the present invention, when the circular protrusion for forming the protrusion nozzle is bored, only that portion is compressed. It is easy to secure the volume, and the bushing base plate can be easily manufactured without any special training or skill. In addition, spinning is possible because continuous mass production is possible with a press machine, a material that is extremely resistant to wettability can be used, and the disadvantage that conventional wettability changes due to the diffusion of Au can be compensated. At the same time, it is possible to obtain a glass fiber spinning device capable of sustaining a structure in which yarn breakage does not easily occur and performing stable spinning.
