본 발명은 매우 가는 강선의 일면에 분말 다이아몬드를 전착하여 각종 자개를 절단하는데 사용하는 자개절단용 띠톱의 제조방법에 관한 것이다. 종래 이와같은 자개절단용 띠톱은 가는 강선을 타원형으로 압연하고 일측상면에서만 분말다이아몬드를 부착시킨 것으로서 강선이 매우 가늘고 길어 일측 상면에만 다이아몬드를 효과적으로 부착시키기 위한 제작공정이 까다롭고 어려운 폐단이 있었다. 따라서 본 발명의 목적은 가는 강선에 분말다이아몬드를 부착하는 효과적인 제조방법을 제공하는데 있다.The present invention relates to a method for producing a mother-of-pearl strip band saw used to cut various mother-of-pearl by electrodepositing powder diamond on one side of a very thin steel wire. In the past, such a mother-of-pearl cutting band saw rolled thin wire in an oval shape, and powder diamond was attached only on one side, and the steel wire was very thin and long, so that the manufacturing process for effectively attaching diamond only on one side was difficult and difficult. Accordingly, it is an object of the present invention to provide an effective method for attaching powder diamond to a thin steel wire.

본 발명의 또다른 목적은 강선의 일측 상면을 평면으로 형성하고 그 상면과 양측 가장자리에 분말다이아몬드를 부착하는 띠톱의 제조방법을 제공하는데 있는 것이다.Another object of the present invention is to provide a method for producing a band saw to form a top surface of one side of the steel wire in a plane and to attach the powder diamond to the top surface and both edges.

이와 본 발명을 첨부도면 및 실시예에 따라 제조공정 순서대로 상술하면 다음과 같다.When the present invention is described in detail in the manufacturing process sequence according to the accompanying drawings and the embodiment as follows.

제1공정1st process

소망하는 직경의 가는 톱날 소재를 압연하여 장타원형상으로 형성한 2가닥의 강선(1) (1')을 옆으로 나란히 면접시켜 접착제가 도포된 일정 크기의 접착판(2)에 중심공간(3)을 두고 나선상으로 상호 연결되게 권착시킴다음 1가닥의 간격유지용 강선(1')을 권착할 때와는 반대방향으로 풀어 접착판(2)으로부터 제거하고 접착판(2)에 1가닥의 강선(1)만이 강선긁기의 간격을 유지하는 상태로 권착하게 한다.(첨부도면의 (a)(a'))The center space (3) is applied to the adhesive plate (2) of a predetermined size by interviewing two strands of steel wire (1) (1 ') formed by rolling a thin saw blade material having a desired diameter into a long ellipse side by side. ) And then spirally interconnected, then loosen in the opposite direction as when the one-strand spacing steel wire (1 ') is wound and removed from the adhesive plate (2). Only the steel wire 1 is wound in a state in which the steel wire scraping is maintained ((a) (a ') in the attached drawing).

제2공정2nd process

제1공정에서 강선(1)이 접착된 접착판(2)보다 더 큰 크기의 두꺼운 백크라이트 도는 PVE판(5)에 에폭시접착제(6)를 얇은 두꼐로 도포하여 그 상면에 매우 얇은 전도용 동판(7) (7')을 끝단이 중심공간(3)의 내부에 위치하도록 방사상으로 접착시키고 제1공정에서 형성된 접착판(2)을 뒤집어 권착된 강선(1)이 동판(7) (7')의 상면에 접면되도록 접착시킨다. 이때 강선(1)은 동판(7) (7')이 매우 얇은 두께이므로 접착판(2)을 뒤집어 접면시키면 동판(7) (7')과 접면되지 않는 부분이 동판(7) (7')의 두께로 인해 미세하고 굴곡되어 에폭시접착제(6)를 매개로 접착판(2)에 긴밀히 접착된다.In the first step, an epoxy adhesive 6 is applied to the thick backlite or PVE plate 5 having a size larger than that of the adhesive plate 2 to which the steel wire 1 is bonded, and a thin thin conductive copper plate is formed on the upper surface thereof. 7) The 7 'is radially bonded so that its end is positioned inside the central space 3, and the steel wire 1 wound upside down is formed by turning the adhesive plate 2 formed in the first step into a copper plate 7 and 7'. Adhesion to the upper surface of the contact. At this time, since the steel wire 1 is a very thin thickness of the copper plate 7 (7 '), when the adhesive plate 2 is turned upside down, the portion that is not in contact with the copper plate 7 (7') is the copper plate 7 (7 '). Due to the thickness of the fine and bent is closely adhered to the adhesive plate 2 via the epoxy adhesive (6).

이어서 에폭시접착제(6)는 액상이므로 경화될때까지 그리고 강선(1)이 평면화되도록 뒤집어진 접착판(2)의 상면에 두꺼운 유리판등을 놓고 프레스로서 약 10시간정도 가압하여 동판(7) (7')과 이의 상면에 중첩된 강선(1)이 에폭시접착제(6)에 의거 PVC판(5)상에 완전히 접착되게한 다음 접착판(2)를 제거시키면 PVC판(5)에 강선(1)이 동판(7) (7')과 함께 에폭시접착제(6)의 경화로 인해 완전히 밀착된 상태로 부착되어진다.Subsequently, the epoxy adhesive 6 is a liquid phase, and a thick glass plate, etc. is placed on the upper surface of the adhesive plate 2 which is turned upside down until it is cured and the steel wire 1 is flattened and pressed for about 10 hours by a copper plate 7 (7 '). ) And the steel wire (1) superimposed on the upper surface thereof is completely adhered to the PVC plate (5) based on the epoxy adhesive (6) and then the adhesive plate (2) is removed, the steel wire (1) to the PVC plate (5) Due to the curing of the epoxy adhesive 6 together with the copper plates 7 and 7 ', they are attached in a completely tight state.

이 상태에서 강선(1)의 내부공간(3)에 환형도통선(8)을 각 동판(7) (7')의 끝단과 납땜시켜 서로 도통되도록 한 후 전해용도선(9)을 연결시킨다.(첨부도면의 (b) (c) (d) (e))In this state, the annular conductive line 8 is soldered to the end of each copper plate 7, 7 ′ in the inner space 3 of the steel wire 1 so that the conductive wire 9 is connected to each other. ((B) (c) (d) (e) in the attached drawing)

제3공정3rd process

다음 PVC판(5)상에 일체로 접착된 강선(1)의 상면에 에폭시수지(10)를 강선(1)이 모두 묻히도록 충진도포하여 상면을 평면화시킨 후 연마포(11)로서 강선(1)의 상면이 곡면에서 평면상태가 될때까지 연마한다. 이때 에폭시수지(10)는 강선(1)보다 약하므로 강선(1)의 상면이 평면 상태가 될때까지 연마를 하면 에폭시수지(10)는 첨부도면의 (g)와 같이 강선보다 더욱 많이 연마되어진다 (첨부도면의 (f) (g))Next, the epoxy resin 10 is filled on the upper surface of the steel wire 1 bonded integrally on the PVC plate 5 so that the steel wire 1 is filled and the upper surface is flattened, and then the steel wire 1 as the polishing cloth 11 is applied. Polish until the top surface of) becomes flat from the curved surface. At this time, since the epoxy resin 10 is weaker than the steel wire 1, when the upper surface of the steel wire 1 is polished until it becomes flat, the epoxy resin 10 is polished more than the steel wire as shown in (g) of the accompanying drawings. ((F) (g) in the attached drawing)

제4공정4th process

이와같은 공정이 완료하면 첨부도면(h)와 같이 공지의 와트액을 전해액으로 다이아몬드입자(12)를 침강시킨 전해조(13)에서 저전압으로 약 30분간 공지의 전착도금을 실시하면 에폭시수지(10)가 연마로 인해 덮혀있지 않은 평면화된 강선(1)의 상면과 측면 가장자리에 다이아몬드 입자(12)가 완전히 밀도있게 피착된다.When such a process is completed, as shown in the attached drawing (h), if the electrodeposition plating is performed at a low voltage for about 30 minutes in the electrolytic cell 13 in which the diamond particles 12 are sedimented with a known watt liquid, the epoxy resin 10 The diamond particles 12 are deposited completely and densely on the top and side edges of the flattened steel wire 1 which is not covered by polishing.

이와같은 전착도금 작업이 완료하면 PVC판(5)으로부터 다이아몬드입자(12)가 피착된 강선(1)을 분리시키면 에폭시수지(10)에 접착된 강선(1)은 쉬이 분리되어지므로 소망하는 크기로 절단하여 용도에 따라 적합한 형태로 사용하면 되는 것이다.When the electrodeposition plating is completed, the steel wire 1 on which the diamond particles 12 are deposited is separated from the PVC plate 5 so that the steel wire 1 adhered to the epoxy resin 10 is easily separated. It can be cut and used in a form suitable for use.

이와같은 본 발명은 강선(1)을 접착판(2)의 상면에 나선상으로 권착하여 제조하므로 긴 길이의 톱날을 간단한 방법에 의해 효과적으로 제조할 수 있고 다이아몬드가 전착된 일측 상면은 종래와는 다르게 연마포(11)로서 연마하여 평평하게 한 상태에서 다이아몬드입자(12)를 피착하여 상면뿐 아니라 상면 가장자리까지 전착한 것이므로 자개, 석재, 유리 등의 회전 절단시 매우 효과적이다.Since the present invention is manufactured by winding the steel wire (1) spirally on the upper surface of the adhesive plate (2) can be effectively manufactured by a simple method of a long length saw blade and one side of the electrode electrodeposited diamond is different from the conventional Since the diamond particles 12 are deposited and polished as the abrasion 11 and flattened to the upper edge as well as the upper edge, they are very effective in rotating cutting of mother-of-pearl, stone, and glass.

실시예Example

선경 0.26m/m의 톱날소재를 두께 0.17mm 폭 0.34mm와 장타원형상으로 압연한 2가닥의 강선을 면접시킨후 접착판에 10cm정도의 중심공간을 두고 약 250m정도를 자선상으로 권착시키고 일정간격이 유지되게 한가닥의 강선을 제거시켰다.Saw blade material with wire diameter of 0.26m / m was interviewed with 0.17mm thickness 0.34mm and 2 strands of steel wire rolled in long oval shape, and then wound about 250m with charity with a center space of 10cm on the adhesive plate. One strand of wire was removed to maintain the gap.

다음에 PVC판에 에폭시접착제를 약 0.1mm의 두께로 도포하고 이에 0.03mm의 전도용 동판을 방사상으로 부착시킨후 강선이 권착된 접착판을 뒤집어 동판의 상면에 중첩되도록 강선을 접착시키고 접착판의 상면에 약 5m/m의 유리판을 덮어 프레스로서 10시간 가압한후 접착판을 벗겨내었더니 강선과 동판은 에폭시접착제의 경화로 인해 PVC판에 긴밀히 접착되어있고 접착판만이 제거되었다.Next, an epoxy adhesive is applied to the PVC plate with a thickness of about 0.1 mm, and the conductive copper plate of 0.03 mm is radially attached thereto. Then, the steel wire is bonded so that the steel plate is overlaid and the steel wire is bonded to overlap the upper surface of the copper plate. The steel plate and copper plate were closely adhered to the PVC plate due to the hardening of the epoxy adhesive, and only the adhesive plate was removed.

이 상태에서 강선의 중심공간에 환형도통선을 각 동판과 연결되도록 납땜시키고 이에 전해용 도선을 접속시켰다.In this state, an annular conductive line was soldered to each copper plate in the center space of the steel wire, and an electrolytic conductive wire was connected thereto.

그 다음 강선의 상면에 에폭시수지를 강선이 모두 묻히도록 충진하고 연마포로서 강선의 상면이 평면으로 노출될때까지 연마하여 와트액을 전해액으로 다이아몬드입자를 침강시킨 전해조에서 0.8A, 0.1V의 미세한 전류로서 약 30분간 전착도금을 실시하였더니 강선의 평면화된 상면과 가장자리에 다이아몬드입자가 고르고 밀도있게 피착되었다.Then, the epoxy resin is filled on the upper surface of the steel wire so that all the steel wire is buried, and the polishing cloth is polished until the upper surface of the steel wire is exposed to the flat surface. After electrodeposition plating for about 30 minutes, diamond particles were deposited evenly and densely on the flattened top and edge of the steel wire.

이어서 전해조에서 강선이 권착된 PVC판을 꺼내어 건조시킨후 강선을 풀어내어 실톱날로서 자개를 절단하였더니 다이아몬드입자의 고르고 밀도있는 접착으로 자개의 절단이 잘 되었으며 다이아몬드입자가 평면으로된 상면뿐 아니라 상면 가장자리에도 피착되어 회전절단시 절단효과가 매우 우수함을 알 수 있었다.Subsequently, after removing the PVC plate on which the steel wire was wound from the electrolytic cell and drying it, the wire was unwrapped and cut off the mother-of-pearl as a jig saw blade. It was also found that the cutting effect was very good at the time of rotary cutting because it was deposited on the edge.
