A nozzle hole 3 is formed in the circular protrusion 2 to form a nozzle 4.

寸法精度が悪かつた。 In such a bushing plate 5, since the nozzle 4 has a thick wall, the molten glass discharged from the nozzle spreads wetly on the tip surface, and the thickness of the thread such as glass fiber to be spun is large and uneven.
The dimensional accuracy was poor.
この為、ノズル４の肉厚を薄くすることが行わ

端部に変形やクラツクが生じ易いものである。 For this reason, the thickness of the nozzle 4 has been reduced by machining the outer periphery of the nozzle 4.
If the wall thickness is reduced to less than mm, the nozzle hole 3 will be easily deformed. In addition, if a nozzle hole 3 is formed in the circular protrusion 2 by punching after protruding the circular protrusion 2 by pressing, etc., and a thin nozzle 4 with a wall thickness of 0.3 mm or less is formed, the tip of the nozzle 4 The parts are easily deformed and cracked.

ある。 The present invention was made to solve this problem, and provides a butting plate that can reduce the thickness of the nozzle tip without deforming the nozzle hole or causing cracks in the nozzle hole. The purpose is to provide a manufacturing method.

を薄くし、先端部を細くするものである。 The method of manufacturing a bushing plate of the present invention is to provide a bushing plate material 1 whose main component is platinum with a large number of circular protrusions 2, as shown in FIG. 2a, and then as shown in FIG. 2b. A nozzle hole 3 is formed concentrically from the back side of the circular protrusion 2 by extrusion processing by punching to form a nozzle 4, and then a large number of circular holes 6 are formed around the outer periphery of the tip of the nozzle 4 as shown in FIG. 2c. The provided electrode 7 is subjected to electric discharge machining to reduce the wall thickness and make the tip portion thinner.

ある。 Incidentally, in order to arrange and protrude a large number of circular protrusions 2 on the bushing plate material 1, the bushing plate material 1 is placed on a mold table and the process is performed by pressing or rolling, or by cutting. The nozzle hole 3 is formed concentrically in the circular protrusion 2 by cutting or extrusion.

られる等の効果を奏する。 As described above, in the method for manufacturing a bushing plate of the present invention, the outer periphery of the tip of the nozzle 4 is subjected to electric discharge machining to reduce the wall thickness and make the tip thinner, so it is easy to use the nozzle 4 with a wall thickness of 0.3 mm or less. Therefore, the tip of the nozzle 4 will not be deformed or cracked. Therefore, this bushing plate 5
When molten glass is discharged from the nozzle 4, the nozzle 4 will not be damaged by the pressure of the molten glass.
In addition, the wetting and spreading at the tip end surface is small, the thickness of the spun glass fiber or other thread is thin, and there is almost no variation, so that it is possible to obtain products with high dimensional accuracy.
