Description
본 발명은 미세한 통과공를 갖는 소결체의 제조방법에 대한 것으로서, 좀 더 상세히는 광케이블 커넥터나 와이어본딩용 캐필러리 등으로 사용되는 소결제품을 효율좋고 고품질로 제작할 수 있는 새로운 방법에 대한 것이다.The present invention relates to a method for producing a sintered body having a fine passage hole, and more particularly to a new method for producing an sintered product used as an optical cable connector or a wire bonding capillary with high efficiency and high quality.
광케이블 커넥터로 사용되는 페롤(Ferrule)이나 반도체칩 와이어본딩용 캐필러리, 또는 보일러의 분사노즐 등으로 사용되는 제품은 세라믹이나 루비 등으로 소결제작되며 미세한 통공 또는 노즐공이 형성된다. 도 1은 이중에서 광케이블 커넥토용 페롤(1)의 일예를 보여주는데, 원통형의 세라믹 소결체(2)의 내부에 중공부(3)가 형성되고, 그 선단에는 미세한 통공(4)이 형성된다. 이러한 페롤의 통공(4)은 직경이 20㎛ 정도에 이르는 미세한 것으로서, 이 페롤을 통해 광케이블이 통과되어 케넥터로 사용된다.Ferrules used as optical cable connectors, capillaries for semiconductor chip wire bonding, or spray nozzles of boilers are manufactured by sintering ceramics or rubies, and fine pores or nozzle holes are formed. FIG. 1 shows an example of a ferrule 1 for an optical cable connector, in which a hollow part 3 is formed inside a cylindrical ceramic sintered body 2, and a fine through hole 4 is formed at a tip thereof. The through hole 4 of the ferrol is a minute diameter of about 20 μm, and the optical cable passes through the ferrol to be used as a connector.
그런데, 이러한 미세통공을 가진 소결체를 제조하는 종래의 방법은 소결체를 소결방법만으로 완성품을 제작하였기 때문에, 소결시 통공(4)이 막히거나 통공(4) 내경의 조도가 불량하여 생산성이 낮고 불량율이 높다는 문제점이 있었다. 또한, 소결체의 규격별로 성형용 몰드를 제작해야 하므로 제작코스트가 높고 다품종 소량생산에 부적합하다는 문제점이 있었다.However, in the conventional method of manufacturing a sintered compact having such micropores, since the finished product is manufactured only by sintering the sintered compact, the through hole 4 is blocked during sintering, or the roughness of the inner diameter of the through hole 4 is poor, resulting in low productivity and low defective rate. There was a problem of high. In addition, there is a problem in that the production mold is high, and the production cost is not suitable for small quantity production of a large variety of products because the mold for molding according to the specifications of the sintered body.
본 발명은 전술한 바와 같은 종래의 미세한 통공을 갖는 소결체의 제조상의 문제점에 착안하여 제안된 것으로서, 저렴한 비용으로 고품질의 정밀한 제품을 제작할 수 있는 새로운 방법을 제공하고자 하는 것이다. 또한, 하나의 몰드로 다양한 규격의 제품을 제작가능하므로 다품종 소량생산에 적합한 제조방법을 제공하고자 하는 것이다.SUMMARY OF THE INVENTION The present invention has been proposed in view of the problems in manufacturing a sintered body having a conventional fine aperture as described above, and is intended to provide a new method for producing a high-quality precise product at low cost. In addition, it is possible to manufacture products of various specifications with a single mold is to provide a manufacturing method suitable for the production of small quantities of various types.

본 발명에 따르면, 일단이 개방되고 타단은 테이퍼진 경사면(6)으로 이루어져서 막힌 중공부(3)가 내부에 형성된 소결체(2)를 소결성형하는 단계와, 경사면(6) 부위에 작은 구멍(7)이 형성되도록 상기 소결체(3)의 막힌 단부를 연마 또는 커팅하는 단계와, 상기 중공부(3)와 작은 구멍(7)을 통해 연마용 와이어(8)를 왕복시킴으로써 상기 구멍(7)을 소정 직경의 통공(4)으로 확개하면서 연마가공하는 단계를 포함하는 것을 특징으로 하는 미세한 통공을 갖는 소결체의 제조방법이 제공된다.According to the present invention, one end is opened and the other end is tapered inclined surface 6 so as to sinter the sintered body 2 in which the blocked hollow portion 3 is formed therein, and the small hole 7 in the inclined surface 6 area. Grinding or cutting the closed end of the sintered body 3 to form a hole, and reciprocating the polishing wire 8 through the hollow part 3 and the small hole 7. Provided is a method for producing a sintered body having a fine through hole, comprising the step of polishing while expanding into a through hole 4 of diameter.
이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 도 2는 본 발명에 따른 방법을 보여주는 공정도로서, 도시된 바와 같이, 먼저, 일단이 개방되고 타단은 테이퍼진 경사면(6)으로 뾰족하게 이루어진 중공부(3)를 갖는 소결체(2)를 소결하여 성형한다(A단계). 다음에, 소결체(2)의 막힌 단부를 연마하거나 기타의 방법으로 커팅하여 경사면(6) 부위가 관통되어 작은 구멍(7)이 형성되도록 한다(B단계). 이 때, 작은 구명의 직경은 최종적으로 형성될 구멍보다 작도록 연마 또는 절단부위를 결정한다. 다음에, 소결체(2)의 중공부(3)와 작은 구멍(7)을 통해 연마용 와이어(8)를 통과시켜서 왕복시킴으로써 작은 구멍(7)의 내경을 연마가공한다. 연마용 와이어(8)는 다이아몬드입자가 부착된 와이어 등을 사용한다. 연마용 와이어(8)로 원하는 직경만큼 구멍(7)을 확개시키면, 내경부가 매끄럽게 마감처리된 정밀한 치수의 최종적인 통공(4)이 얻어진다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. Figure 2 is a process diagram showing the method according to the invention, as shown, first, by sintering the sintered body (2) having a hollow portion (3), one end of which is opened and the other end is made of a tapered inclined surface (6) Molding (step A). Next, the closed end of the sintered body 2 is polished or cut by other methods so that the inclined surface 6 portion is penetrated to form a small hole 7 (step B). At this time, the diameter of the small sphere determines the grinding or cutting site to be smaller than the hole to be finally formed. Next, the inner diameter of the small hole 7 is polished by passing the polishing wire 8 through the hollow portion 3 and the small hole 7 of the sintered body 2 and reciprocating. The polishing wire 8 uses a wire with diamond particles attached thereto. By expanding the hole 7 by the desired diameter with the polishing wire 8, a final through hole 4 of precise dimensions having an inner diameter smoothly finished is obtained.
이러한 방법에 의하면, 통공(4)을 직접 소결성형하는 종래의 방법과는 달리, 통공이 막히거나 내경부의 조도가 떨어지는 문제가 없고, 내경을 정밀하고 매끄럽게 가공할 수 있다. 또한, 연마용 와이어(8)로 원하는 직경만큼 확개할 수 있어서, 사용되는 광케이블 커넥터나 골드와이어가 달라지더라도 별도의 몰드를 사용하기 않고도 통공(4)의 크기를 조절할 수 있어서 제작코스트가 절감되고 다품종 소량생산에 적합한 새로운 미세통공을 갖느 소결체의 제조방법이 제공되게 된다.According to this method, unlike the conventional method of directly sintering the through hole 4, the inside diameter can be processed precisely and smoothly without the problem of clogging the hole or falling of the roughness of the inner diameter portion. In addition, the polishing wire 8 can be expanded to the desired diameter, and even if the optical cable connector or the gold wire used is changed, the size of the through hole 4 can be adjusted without using a separate mold, thereby reducing the manufacturing cost. There is provided a method for producing a sintered body having a new micro-perforation suitable for small quantities of multi-products.
