Abstract

In manufg. a band saw for cutting mother-of-pearl, a steel wire (1) is passed through holes that are formed on both sides of a plastic or metallic bowl (2) filled with lacquer or resin (4). A diamond powder layer is formed on the lacquered or resined steel wire. In the section of wire the long diameter is 2.5-3.5 m/m and the short diameter is 0.2-0.25 m/m before lacquering. After lacquering the long diameter is 2.6-3.6 m/m and the short diameter is 0.25-03. m/m. The diamond powder layer formed is thicker thant the steel wire by 0.08- 0.15 m/m.

본 발명은 자개패(貝)에서 자개를 일정한 두께로 떠내는 띠톱을 제조함에 있어서, 가느다란 강철선에 다이아몬드 분말을 전착시키되, 다이아몬드 분말층을 강철선의 두께의 폭보다 넓게 전착되게 하는 자개를 떠내는 띠톱의 제조방법에 관한 것이다.The present invention in the manufacture of a band saw floating the mother-of-pearl in a constant thickness in the mother-of-pearl, electrodeposited diamond powder on a thin steel wire, to remove the mother-of-pearl electrodeposited diamond powder layer is wider than the width of the steel wire A method for producing a band saw.

종래에는 자개패(貝)를 엷게 만들기 위해서는 고가의 자개패를 연마저석으로 갈아서 소요의 두께만큼 엷게 가공한 후 연마포로 표면을 연마하여 광택을 내게 하였으나.Conventionally, in order to make the mother-of-pearl thin, the mother-of-pearl has been polished by grinding the surface of the mother-of-pearl in order to make the mother-of-pearl expensive.

이와 같은 가공방법은 자개패에서 엷은 자개를 떠내는 띠톱이 없었기 때문에 부득이한 공정이었다.This processing method was inevitable because there was no band saw to remove the thin mother-of-pearl from the mother-of-pearl.

따라서 수입에 의존하는 고가의 자개패를 연마저석으로 소요두께만큼 엷게갈아 자개의 손실이 많음으로 인한 외화의 낭비는 물론이거니와 경제적으로도 손실이 지대하였다.Therefore, the expensive mother-of-pearl, which depends on imports, was thinned to the required thickness by grinding stone, which was not only a waste of foreign currency due to the loss of mother-of-pearl.

그리고 엷게 연마가공한 자개를 띠톱으로 각 무늬를 절삭 가공하여 피착물에 부착하는 것인데, 이 절삭 띠톱은 다이몬드 분말층이 강철선과 같은 두께로 강철선의 반원부분에 전착된 것으로 이 절삭 띠톱으로 자개패에서 엷은 자개를 떠내려고 시도하였으나 띠톱이 원형으로 생긴 자개패의 원심력 방향으로 진행되어 도저히 엷은 자개를 떠낼 수 없었다.A thinly ground mother-of-pearl is used to cut each pattern with a band saw and attach it to the adherend. This cutting band saw is a diamond powder layer electrodeposited to the semicircle of the steel wire with the same thickness as the steel wire. Attempts were made to remove the thin mother-of-pearl, but the band saw proceeded in the direction of the centrifugal force of the mother-of-pearl, which was circular.

즉, 상하회전륜의 걸린 절삭 띠톱을 회전시키고 자개패를 띠톱의 다이아몬드 분말층에 압압하면서 자개패를 자개패의 원방향으로 돌릴 때 띠톱의 전행방향이 원심력 방향으로 진행되어 엷은 자개를 떠낼 수 없는 원인은 다이아몬드 분말층과 장원형 강철선의 두께가 단면으로 볼 때 일직선으로 되어 있어서 강철선의 절삭 진행 방향을 변경할 수 없음을 발견하고 다이아몬드 분말층을 장원형 강철선의 두께보다 두껍게 전착하면 다이아몬드에 의한 절삭부분이 두께보다 넓어지므로 강철선의 절삭진행 방향을 자개패의 원방향으로 서서히 바꿀 수 있을 것이라는 점에 착안하였다.That is, when rotating the cutting band saw of the up and down wheels and pressing the mother-of-pearl into the diamond powder layer of the band saw, when the mother-of-pearl turns in the direction of the mother-of-pearl, the direction of the band saw proceeds in the direction of the centrifugal force so that the mother-of-pearl cannot be removed The cause is that the thickness of the diamond powder layer and the rectangular steel wire is in a straight line, so that the direction of cutting of the steel wire cannot be changed, and when the diamond powder layer is electrodeposited thicker than the thickness of the long steel wire, the cutting part by diamond Since it is wider than this thickness, it was conceived that the cutting direction of the steel wire could be gradually changed in the original direction of the mother-of-pearl.

만일, 다이아몬드 분말층을 장원형 강철선의 두께보다 너무 두껍게 하면 자개패의 절삭량이 많아져서 자개패의 허실을 초래하게 될 것이어서 많은 실험끝에 다이아몬드 분말층이 강철선의 두께보다 약 0.1m/m정도 두껍게 전착하는 것이 바람직한 것으로서 본 발명은 이의 균일 전착을 위한 신규한 제조방법을 제공함에 목적이 있는 것이다.If the diamond powder layer is made thicker than the thickness of the long steel wire, the cutting amount of mother-of-pearl will increase and cause loss of mother-of-pearl. As a result of many experiments, the diamond powder layer is electrodeposited about 0.1m / m thicker than the thickness of the steel wire. It is an object of the present invention to provide a novel manufacturing method for the uniform electrodeposition thereof.

이하 본 발명을 도면의 실시예에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the embodiments of the drawings.

플라스틱통이나 금속재통(2)의 하부양쪽에 단면이 장원형인 강철선(1)의 굵기보다 약 0.1m/m정도 큰 장공(3)(3')을 천설하고, 강철선(1)을 양쪽 장공(3)(3')에 관통시켜 놓은 다음, 락카 또는 수지(4)를 플라스틱통(2)에 가득 채운 후 강철선(1)을 통과시켜 장공(3')에서 권측(5)까지 서서히 가는 동안에 락카가 건조되어 락카가 도포된 강철선(1')을 얻는다.Long holes (3) (3 ') of about 0.1 m / m larger than the thickness of the steel wire (1) having a cross section are installed on both lower parts of the plastic or metal container (2), and the steel wire (1) is installed on both sides. (3) (3 '), and then fill the plastic container (2) with the lacquer or resin (4) and pass it through the steel wire (1) while slowly moving from the long hole (3') to the winding side (5). The lacquer is dried to obtain a steel wire 1 'coated with the lacquer.

락카를 도포하기전 권측(5')의 강철선의 굵기는 단면상으로 볼 때 장원형의 장방향 길이는 2.5-3.5m/m 장원형의 짧은 방향쪽 두께는 0.2-0.25m/m이고, 락카를 도포한 후의 장방향의 길이는 2.6-3.6m/m이고, 두께는 0.25-0.3m/m이다.The thickness of the steel wire on the winding side (5 ') before application of the lacquer is in cross section, and the longitudinal length of the rectangular shape is 2.5-3.5m / m, and the shorter thickness of the rectangular shape is 0.2-0.25m / m. The length in the longitudinal direction after coating is 2.6-3.6 m / m, and the thickness is 0.25-0.3 m / m.

이와 같이 락카(4)를 강철선(1)에 도포한 강철선(1')을 건조상태로 권측(5)에 감은 다음 두꺼운 훼놀 수지원반(6)에 에폭시수지(7)를 도포하고 즉시원반의 중심환(中心環)에서 부터 락카도포 강철선(1')을 축음기판 모양으로 연접 권착하여 충분히 경화 시킨 후에 철선솔로 강철선(1')의 권착 표면을 솔질하여 강철선(1')의 반원 부분의 락카(4) 및 에폭시수지(7)를 제거한 후(제3도 참조) 공지의 방법으로 다이아몬드 분말을 전착하면 락카 두께만큼 다이아몬드 분말층(8)이 강철선의 두께의 폭보다 넓게 형성되는 것이다.In this manner, the steel wire 1 'coated with the lacquer 4 on the steel wire 1 is wound on the winding side 5 in a dry state, and then the epoxy resin 7 is applied to the thick phenolic support plate 6, and immediately the center of the disc. Lacca coated steel wire (1 ') is spun up and hardened in the shape of a phonograph from the ring, and then the wire surface of the steel wire (1') is brushed and the lacquer of the semicircle of the steel wire (1 ') is brushed. 4) and the epoxy resin 7 is removed (see FIG. 3), the electrode powder is electrodeposited by a known method, so that the diamond powder layer 8 is formed wider than the thickness of the steel wire by the thickness of the lacquer.

이렇게 전착작업이 끝나면 강철선의 외주 연단부를 잡고 잡아때면 락카(4)와 에폭시수지(7)는 원반에 고착된채 다이아몬드 분말층(8)을 전착한 띠톱(9)만이 분리되는 것이다.When the electrodeposition work is finished, when holding the outer edge of the steel wire and grab the lacquer (4) and epoxy resin (7) is only the band saw (9) electrodeposited diamond powder layer (8) is fixed to the disc.

즉, 제4도의 도면과 같이 다이아몬드 분말층(8)이 강철선의 두께보다 0.08-0.15m/m 두껍게 형성되는 것이다.That is, as shown in FIG. 4, the diamond powder layer 8 is formed to be 0.08-0.15 m / m thicker than the thickness of the steel wire.

본 발명은 상기와 같이 강철선에 다이아몬드 분말층을 일정 두께로 전착되게한 띠톱을 용이하게 양산할 수 있게함으로써 자개 가공용 띠톱을 저렴하게 제공함은 물론 수입에 의존하는 고가의 자개패를 가공시에 손실을 최대한 줄여 외화를 절약할 수 있게 한 효과가 있는 것이다.The present invention makes it easy to mass-produce a band saw obtained by depositing a diamond powder layer on a steel wire in a predetermined thickness as described above, and provides a strip saw for mother-of-pearl processing at a low cost as well as loss at the time of processing an expensive mother-of-pearl that depends on imports. It is effective in reducing foreign currency as much as possible.
