本発明は紡糸口金の孔明け方法に係り、特に溶
融ポリマーの吐出孔を貫通穿設する孔明け方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for making holes in a spinneret, and more particularly to a method for making holes for discharging molten polymer through the spinneret.
従来、紡糸口金を孔明けするには、第１図ａに

に、第１図ｂに示す如くパンチ工具３による孔明
け加工にて吐出孔４を貫通穿設している。 Conventionally, in order to make a hole in a spinneret, as shown in FIG. In order to obtain a mirror-like discharge hole, the discharge hole 4 is punched through by drilling with a punch tool 3, as shown in FIG. 1B.

点があつた。 However, among the spinneret plates 1, the spinneret plate made of austenitic stainless steel material can be penetrated by drilling approximately 1,000 to 2,000 holes when the discharge holes 4 are punched through by drilling with the punch tool 3. The inner circumferential surface of the discharge hole 4 provided was a rough surface with no luster, resulting in a disadvantage that a spinneret of poor quality was produced.

の際、第２図に示す如く付着物５が吐出孔４の内
周面を掻き削るからである。 The reason why the inner peripheral surface of the discharge hole 4 becomes a dull and rough surface as described above is due to the seizure phenomenon between the punch tool 3 and the spinneret plate 1 made of stainless steel material during the hole drilling process shown in FIG. 1b. As shown in FIG. 2, stainless steel material adheres to the tip 3a of the punch tool 3, the deposit 5 grows, and after drilling approximately 1000 to 2000 holes, the punch tool 3
The tip 3a of the punch tool 3 completely adheres to the inner circumferential surface of the discharge hole 4 through the deposit 5, and as a result, when the punch tool 3 is raised, the deposit 5 is attached to the inner circumference of the discharge hole 4 as shown in FIG. This is because it scrapes the surface.

３の焼き付き防止効果が殆んど無かつた。 For this reason, conventionally, in order to prevent the tip 3a of the punch tool 3 from seizing, lubricating oil is applied to the upper surface of the spinneret plate 1 made of stainless steel as shown in FIG. However, near the final part of the drilling process of the discharge hole 4, the lubricating oil 6 does not flow up to the tip 3a of the punch tool 3 as shown in FIG. 3b. The anti-seize effect of No. 3 was almost absent.
本発明はかかる実情に鑑みなされたものであ

る。 The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method for drilling a spinneret, which does not cause the sticking phenomenon of the punch tool and is capable of penetrating a discharge hole having a mirror-like luster. .
以下本発明による紡糸口金の孔明け方法を図に

を穿設する。 The method for making holes in a spinneret according to the present invention will be explained below with reference to the drawings. As shown in FIG. 4a, a metal such as Al, Cu, Pb, In, Ag, Au, Sn, brass, etc. A spinneret plate 1 made of stainless steel having a polymer guide hole 2 pre-drilled in the form of a blind hole is placed and fixed thereon.
After that, the bottom of the polymer guide hole 2 of the spinneret plate 1 is
As shown in Figure b, use the punch tool 3 to penetrate the discharge hole 4.

鏡面光沢となる。 By drilling the discharge hole 4 in this way, the tip 3a' of the punch tool 3 that has passed through the discharge hole 4 is
As shown in the figure, since the metal lubricating thin plate 8 is pierced, components of the metal lubricating thin plate 8 adhere to the tip 3a' of the punch tool 3 as shown in FIG. The lubricant acts as a lubricant and disappears until the discharge hole 4 is completely drilled through the bottom of the lubricant.
Then, the tip 3a' of the punch tool 3 pierces the thin metal lubricating plate 8 again, so that the components of the thin metal lubricating plate 8 adhere to the tip 3a' of the punch tool 3.
Thus, each time the discharge holes 4 are drilled through the bottoms of the large number of polymer guide holes 2, the deposits 9 of the components of the lubricating thin metal plate 8 that adhere to the tip 3a' of the punch tool 3 serve as a lubricant. Disappear. Therefore, the tip end 3a of the punch tool 3 does not stick to the spinneret plate 1, and the inner circumferential surfaces of all the discharge holes 4 formed through the spinneret plate 1 have a mirror-like luster.

金１１を完成せしめる。 After the discharge holes 4 are formed through the bottoms of all the polymer guide holes 2 of the spinneret plate 1, the spinning surface 1a of the spinneret plate 1 is polished to form a protrusion 1 on the periphery of the tip of each discharge hole 4.
The spinneret 11 is completed by removing the 0 and making it smooth as shown in FIG.

という優れた効果がある。 As described in detail above, according to the method for making holes in a spinneret according to the present invention, a punch tool is used to make discharge holes through the bottoms of thousands to tens of thousands of pre-drilled polymer holes in a spinneret plate. Even if the punch tool is installed, the punch tool will not seize, and the inner circumferential surfaces of all the discharge holes will have a mirror-like luster, resulting in an excellent effect that a spinneret of good quality can be obtained.
