금속절단용 톱Metal cutting saw

제1도는 본 고안으로 된 톱의 요부발췌도.Figure 1 is an excerpt of the top portion of the saw according to the present invention.

제2도는 제1도의 A-A선 단면도.2 is a sectional view taken along the line A-A of FIG.

제3도는 제2도의 "가"부 확대도이다.FIG. 3 is an enlarged view of part “a” of FIG. 2.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 톱날 몸체 1' : 다수의 요홈1: saw blade body 1 ': a plurality of grooves

2 : 초경합급 가루2: cemented carbide powder

본 고안은 여러가지 톱 가운데서 금속부재를 절단하는데에 사용하는 금속절단용 톱에 관한 것으로, 특히 톱 몸체의 톱날주위 표면에 적절한 방법으로 미세한 초경합금 가루를 부착시켜 줌으로써 톱의 수명을 연장함과 동시에 톱의 절단효율을 향상시키도록 한 것이다. 종래에는 이러한 급속절단용 톱을 만들때 강자체를 열처리하여 비교적 높은 강도와 내마모성을 부여한 공구강을 그대로 가공제작하였는데 이와 같이 만들어낸 톱은 일반 목재용 톱에 비해 그 강도와 내마모성이 매우 높다하겠으나 단단한 금속부재를 장시간에 걸쳐 절단해내기는 아직 톱날의 강도가 미흡하고, 절단 작업시 톱날의 표면이 금속부재에 직접 접촉마찰됨으로써 장시간의 절삭작업에 따른 톱날 온도의 상승과 함께 이른바 열기전력현상이 크게 유발되어 톱날의 수명이 급속히 짧아지므로 톱을 자주 교체해 주어야 하는 것등의 폐단이 있었다.The present invention relates to a metal cutting saw used to cut a metal member among various saws, and in particular, by attaching fine cemented carbide powder to the surface around the saw blade of the saw body in an appropriate manner to extend the life of the saw and at the same time It is to improve the cutting efficiency. Conventionally, when making such a rapid cutting saw, the steel is heat-treated to produce a tool steel that has been given relatively high strength and wear resistance as it is. The saw produced has a higher strength and abrasion resistance than a general wood saw. The cutting of the member for a long time is not enough strength of the saw blade, and the surface of the saw blade is directly rubbed with the metal member during the cutting operation, so that the saw blade temperature increases with the cutting work for a long time. Since the life of the saw blades is shortened rapidly, there have been discontinuities such as the need to frequently change saws.

본 고안은 이러한 점에 착안하여 안출한 것으로 통상의 금속절단용 톱에 있어서 그 톱날주위의 표면에 소정의 초경합금가루를 적절한 방법으로 부착시켜 줌으로써 상술한 바와 같은 종래의 톱이 안고 있었던 문제점들을 일소토록한 것이다. 즉, 본 고안은 일반적인 금속절단용 톱에 있어서 그 톱날 몸체(1) 주위의 표면에 미세한 요홈(1')들을 수없이 형성하여 그 표면적을 넓힌 다음 이에 탄화텅스턴이나 탄화티탄등으로된 초경합금 가루(2)를 적절한 방법으로 랜덤(RANDOM)하게 부착시켜서 된 것이다.The present invention has been devised in view of this point, and by attaching a predetermined cemented carbide powder to the surface around the saw blade in a proper metal cutting saw in an appropriate manner to eliminate the problems of the conventional saw as described above. It is. That is, in the present invention, in the saw for general metal cutting, a number of fine grooves 1 'are formed on the surface around the saw blade body 1 to increase the surface area, and then cemented carbide powder made of tungsten carbide or titanium carbide. It was made by attaching (2) randomly (RANDOM) by an appropriate method.

이와 같이 구성된 본 고안의 톱은, 톱날몸체(1)주위의 표면에 부착된 초경합금가루(2)가 톱날을 보호하여 수명을 연장하고, 절단작업시 톱날몸체(1)의 표면이 피절단부재에 직접적으로 접촉 마찰됨으로써 야기되는 열기전력 현상을 크게 배제하여 주며, 동시에 톱날본연의 절삭작용과 함께 피절단부재와의 사이에 소정의 연삭작용을 이중적으로 발휘하게 됨으로써 톱으로 하여금 높은 절단효율을 발휘토록하는 것 등의 장점을 지닌 것이다.According to the saw of the present invention configured as described above, the cemented carbide powder (2) attached to the surface around the saw blade body (1) protects the saw blade and extends the life, and the surface of the saw blade body (1) is cut to the cutting member during the cutting operation. The thermal power phenomenon caused by direct contact friction is largely eliminated, and at the same time, the saw blade has a high cutting efficiency by simultaneously performing a predetermined grinding action between the cutting member and the cutting member. It has the advantage of doing.

한편, 이러한 본 고안중 톱날몸체(1) 주위의 표면에 미세한 요홈(1')들을 형성하여 그 표면적을 넓히는 것은 상기 초경합금 가루(2)의 부착효율을 높이기 위한 것이며 그 방법으로는 화학적인 부식수단과 함께 샌드블라스트 기법등을 병용한다.On the other hand, in the present invention to form a fine groove (1 ') on the surface around the saw blade body (1) to increase the surface area is to increase the adhesion efficiency of the cemented carbide powder (2) by the method of chemical corrosion means Sandblasting techniques are used together.

이상에서 설명한 바와 같이 본 고안은 톱날 주변에 초경합금 가루를 적절히 부착한 금속절단용 톱으로서 톱의 수명이 매우 길고 절단효율이 높은 것등의 장점을 지닌 것이다.As described above, the present invention is a metal cutting saw having a cemented carbide powder adhering to a saw blade periphery, which has advantages such as a very long service life and a high cutting efficiency.
