Description

원형 톱날 제조방법{A METHOD FOR MANUFACTURING THE CIRCULAR SAW BLADE}Circular saw blade manufacturing method {A METHOD FOR MANUFACTURING THE CIRCULAR SAW BLADE}

본 발명은 석재를 절단하는데 사용하는 원형 톱날 제조방법에 관한 것으로, 보다 상세하게는 석재 등 다양한 고형물질의 형태 및 길이로 절단 제조할 수 있는 인조 다이아몬드 원형 톱날 제조방법에 관한 것이다.The present invention relates to a method for manufacturing circular saw blades used to cut stones, and more particularly, to a method for manufacturing artificial diamond circular saw blades that can be cut into various solid materials such as stones.

종래에 석재를 절단하는 원형 톱날에 있어서는 원형 동판의 외주 단면에 일정 간격으로 깊이 0.5 ~ 1.5 ㎜ 정도의 요홈을 천설하여 이에 연마용 미세 분말을 접합제를 혼합 교반하여서 이루어진 결정 경금속 절단용 동판 톱으로 구성된다.Conventionally, in the circular saw blade for cutting stone, a groove having a depth of about 0.5 to 1.5 mm is laid on the outer circumferential end surface of the circular copper plate at a predetermined interval. It is composed.

즉, 일반적으로 석재를 절단하기 위한 원형 톱날은 코발트, 동분, 석분, 니켈, 철분 등의 첨가물과 혼합 교반시켜 냉간 프레스, 열간 프레스, 드레싱, 연마, 내경 작업 및 도장의 제조 과정을 통해 생산하고 있다.That is, generally, circular saw blades for cutting stone are mixed and stirred with additives such as cobalt, copper powder, stone powder, nickel and iron powder, and are produced through the manufacturing process of cold press, hot press, dressing, polishing, inner diameter work and painting. .

이와 같이 제조된 원형 톱날을 제조할 수 있는 지금까지의 공법은 상기 파우더를 성형틀로 가압 프레스시키면서 원형상의 커터로 인발 가공되었으며, 이와 같이 제조된 원형 톱날을 통해 목재, 석재 기타 연삭 및 절단에 사용되도록 톱날이 회전되는 절단커터가 일정 길이로 절단시켜 원하는 형상으로 가공할 수 있도록 하였다.The conventional method for producing circular saw blades manufactured as described above has been drawn into a circular cutter while pressing the powder into a molding die, and is used for grinding and cutting wood, stone, etc. through the circular saw blades thus manufactured. The cutting cutter is rotated so that the saw blade is rotated to a certain length to be processed into the desired shape.

그러나, 종래의 원형 톱날 제조방법은 톱날의 상하 외주 테두리가 톱날 본체와 동일 두께를 유지하고, 단지 외주 테두리상에 일정 간격으로 요홈을 굴삭하여서 이루어진 것으로서 석재를 절단하는 경우 톱날의 두께와 거의 동일한 절삭 간격을 가지므로 석재로부터 부서진 미세 돌가루가 회전되는 톱날의 양면에 밀착되어 톱날의 회전을 방해하는 요소가 되었다.However, according to the conventional method of manufacturing a circular saw blade, the upper and lower circumferential edges of the saw blade maintain the same thickness as the saw blade main body, and are merely made by digging grooves at regular intervals on the outer circumference, and when cutting stone, the cutting is almost equal to the thickness of the saw blade. Because of the spacing, the fine stone powder broken from the stone is in close contact with both sides of the saw blade to be rotated to become an element that hinders the rotation of the saw blade.

또한, 이러한 종래 원형 톱날은 일정 기간의 사용후 톱날 외형 부분이 흠집이 생겨서 사용할 수 없게 되고, 절삭과정에서는 이러한 흠집으로 분쇄된 칩 등이 사람에게 튀어서 화상 및 외과적 상처를 입히는 결점이 있었다.In addition, such a conventional circular saw blade after use for a certain period of time, the outer surface of the saw blade is scratched and can not be used, and during the cutting process, the chip crushed by such a scratch, such as splashes and wounds to injure people.

아울러 원형 톱날 제조에 있어서, 일정하게 인조 다이아몬드가 원형 테두리에 코팅되어 절단된 슬러지가 적절하게 외부 배출되지 못해 작업환경이 대단히 열악하면서 작업이 불편하다는 등의 여러 단점이 있었다.In addition, in the manufacture of circular saw blades, there were various disadvantages, such as uncomfortable work due to a very poor working environment because the sludge cut by a constant diamond coated on the circular rim is not properly discharged outside.

이에 본 발명은 종래의 즉석 원형 톱날이 제반 불편한 점을 해결하기 위해 안출된 원형 톱날의 제조방법으로 원주 테두리와 석재 절삭면의 슬립을 향상시키고 석재 절단시 미세 돌가루를 보다 효율적으로 외부로 송출시키기 위한 구조로서, 본 발명은 인조 다이야몬드 원형 톱날에 있어서, 통상적인 제1 톱날부와, 이 제1 톱날부 보다 연장 형성된 제2 톱날부를 구성함으로써 원형 톱날의 코팅층 형성 방법을 보다 효과적으로 개선하고, 이들 원형 톱날부의 코팅층의 혼합 성분 및 조성 비율을 개선함으로서 원형 톱날부의 코팅층의 내마모성 및 경도를 증대하여 원형 톱날의 수명 연장을 도모하는 동시에 절삭력을 향상시키는 원형 톱날의 제조방법을 제공하는 데에 그 목적이 있다.Therefore, the present invention is to improve the slip of the circumferential edge and stone cutting surface by the manufacturing method of the circular saw blade devised in order to solve all the inconveniences of the conventional instant circular saw blade and to send the fine stone powder to the outside more efficiently when cutting the stone. As a structure for the purpose of the present invention, in the artificial diamond circular saw blade, the conventional first saw blade portion and the second saw blade portion extending from the first saw blade portion are formed to more effectively improve the coating layer forming method of the circular saw blade, and The purpose of the present invention is to provide a method of manufacturing a circular saw blade which improves the cutting force while improving the wear resistance and hardness of the coating layer of the circular saw blade, thereby improving the wear resistance and hardness of the coating layer. have.

그리고, 상기와 같은 방법으로 원형 톱날의 절단에 코팅층을 형성함에 있어서, 상기 분말체중 코발트, 동분, 석분, 철분, 니켈, 텅스텐이 각각 21.6%, 44.7%, 10.3%, 4.3%, 5.2%, 14%의 성분과 조성 비율을 사용한다.In forming the coating layer on the cutting of the circular saw blade in the same manner as described above, the powder weight of cobalt, copper powder, stone powder, iron powder, nickel and tungsten is 21.6%, 44.7%, 10.3%, 4.3%, 5.2% and 14, respectively. Use the percentage components and composition.

한편, 냉간 프레스 공정에서는 인조 다이아몬드와 분말체를 혼합하여 압력을 가해 원형 주철제에 성형한다. 이와 같이 성형된 원형 주철제를 약 1000℃ 가 되는 열간 노에 넣어서 열처리한다.On the other hand, in the cold press process, artificial diamond and powder are mixed and pressurized and molded into circular cast iron. The circular cast iron thus formed is subjected to heat treatment by placing it in a hot furnace of about 1000 ° C.

이와 같이 열간 노에서 열처리된 다음 팁 부분(본원에서 톱날(12, 14) 부분만을 연마석으로 연삭처리하여 절삭 부분이 노출되도록 한다.The heat treatment in the hot furnace is followed by grinding only the tip portion (saw blades 12 and 14 here) with abrasive stone to expose the cutting portion.

그리고, 원형체 표면 및 중앙의 원형 구멍(16)을 다시 매끄러운 숫돌로 연마하는 공정을 행한다. 이와 같이 형성된 원형 톱날은 페인트로 도장 처리되어 완성된다.Then, the surface of the circular body and the central circular hole 16 are polished again with a smooth grindstone. The circular saw blade thus formed is painted and finished with paint.

이와 같이 금속 합금 분말 및 다이아몬드 분말 등을 열처리하여 톱날 본체(10)의 상하 양면 원주 테두리(20)에 일정 폭으로 용착시키는 절단용 원형 톱날에 있어서, 이 톱날 본체(10)의 상하 원주 테두리(20)를 따라 코팅 돌조(18)가 형성되며, 이 코팅 돌조(18)에는 일정 간격으로 제1 톱날(12) 및 제2 톱날(14)이 형성되어 있다.Thus, in the circular saw blade for cutting which heat-treats a metal alloy powder, a diamond powder, etc., and welds it to the upper and lower double-sided circumferential edges 20 of the saw blade main body 10 with a fixed width, the upper and lower circumferential edges 20 of this saw blade main body 10 A coating protrusion 18 is formed along the top surface, and the first and second saw blades 12 and 14 are formed at regular intervals.

이와 같이 구성된 본 발명은 종래 톱날 원주 테두리의 높이와 동일 또는 근사 높이로 이루어져, 코팅 돌조(18) 끼리의 사이에는 제1 톱날(12)과 제2 톱날(14)이 서로 단으로 구성되어 절삭면을 타고 밀려나는 미세 돌가루를 이들 홈 사이를 통해 외부로 송출하게 된다.The present invention configured as described above has the same or approximate height as the height of the conventional saw blade circumferential edge, and the first saw blade 12 and the second saw blade 14 are composed of the cutting edges between the coating protrusions 18, respectively. The fine stone powder pushed out by the air is sent out through the grooves.

따라서, 종래의 일정한 홈 깊이를 갖는 원주 테두리에 밀착된 미세 돌가루에 의한 톱날 본체의 슬립을 방해하는 저항력이 없어지고, 상기와 같은 구성 및 작용을 갖는 인조 다이아몬드 원형 톱날의 제조방법은 기존의 인조 다이아몬드 원형 톱날에 비하여 고강도 및 고경도를 가져 내마모율이 향상되어 제품의 사용 수명이 연장되고 절삭력이 향상할 수 있는 효과가 제공된다.Therefore, the resistance to hinder the slip of the saw blade main body by the fine stone powder adhered to the circumferential edge having a constant groove depth of the prior art is eliminated, the manufacturing method of artificial diamond circular saw blade having the configuration and action as described above is Compared to diamond circular saw blades, it has higher strength and higher hardness, which improves the wear resistance, thereby extending the service life of the product and improving the cutting force.

또한, 톱날 본체의 회전을 원활하게 유지 운영할 수 있으므로 석재 양 절삭면과 원주 테두리의 편평한 양면이 접촉되는 틈이 적어 지나치게 밀착되어(돌가루에 의한 밀착력 가중도 그 원인이 됨) 절삭 깊이가 깊어질수록 톱날 본체의 회전 속도는 점점 감소하게 되어, 이에 따라 톱날 본체를 빼내어 회전시킨 뒤 절삭 간격을 따라 다시 일정 깊이로 집어 넣어 회전 절삭하여 작업상의 번거로운 점은 물론 톱날을 집어 넣거나 빼낼 경우 상당한 힘이 요구되는 결점도 해결하였다.In addition, since the saw blade main body can be smoothly maintained and operated, the gap between the stone cutting surface and the flat both sides of the circumferential edge is in contact with each other and is too close (caused by the weight of adhesion due to the stone). As the cutting speed decreases, the rotation speed of the saw blade body decreases gradually. Accordingly, the saw blade body is pulled out and rotated, and then the cutting blade is inserted back to a certain depth along the cutting interval to rotate and cut. The required drawbacks were also addressed.
