Abstract

PURPOSE: A cutting saw for preventing noise is provided to reduce a noise by noise preventing member without melting the noise preventing member and to improve cutting work by selectively using cooling water. CONSTITUTION: A cutting saw for preventing noise comprises a cutting saw(10) having an iron plate(12); a through hole(18) formed on the iron plate; and a noise-preventing member(20) mounted in the through hole. The noise-preventing member is composed of lead, copper, zinc, silver, and aluminum. The cutting saw generates noise by cutting friction while cutting a material. Then, the noise-preventing member absorbs vibration of the cutting saw to prevent the noise of the cutting saw. The melting point of the noise-preventing member is higher than the melting point of the iron plate. Thereby, the noise-preventing member prevents the noise without melting the noise-preventing member. Moreover, the cutting saw for preventing noise improves cutting work by selectively using cooling water. The cutting saw for preventing noise performs the noise preventing function without using the cooling water in cutting the material.

Description

소음방지용 절삭톱 {Cutting Saw for Noise Prevention}Cutting Saw for Noise Prevention

본 발명은 절삭방지용 절삭톱에 관한 것으로, 보다 상세하게는 절삭톱의 내부에 비교적 전성이 좋고 융점이 높은 소음방지부재를 내장시킴으로써, 마찰열에 의해 절삭톱이 고온으로 형성되더라도 소음방지부재가 융해됨이 없이 소음을 감소시킬 수 있고, 아울러 냉각수의 사용이 선택적이어서 절삭의 작업성을 한층 높일 수 있는 것이다.The present invention relates to an anti-cutting saw, and more particularly, by embedding a noise suppression member having relatively high malleability and high melting point inside the cutting saw, so that the noise preventing member is melted even when the cutting saw is formed at a high temperature by frictional heat. Noise can be reduced without this, and the use of coolant is optional, further improving the workability of the cutting.

첨부된 예시도면 도 1 및 도 2는 일반적으로 도로나 건물 또는 암석등을 절삭하고자 사용되는 소음방지용 절삭톱(10)을 나타낸 것으로, 먼저 원형의 철판(12) 선단에는 일정길이 만큼 내측으로 절개되는 다수개의 절개부(14)가 원주를 따라 등간격으로 형성되어 있고, 상기 철판(12) 선단에는 절삭팁이나 커터가 용접되는 것이다.1 and 2 show a noise preventing cutting saw 10 which is generally used to cut a road, a building, or a rock, and is first cut inward by a predetermined length at the tip of a circular iron plate 12. A plurality of cutouts 14 are formed at equal intervals along the circumference, and a cutting tip or a cutter is welded to the tip of the iron plate 12.

또한, 상기 철판(12)상에는 일정한 형태를 이루며 절개된 관통공(18)이 다수개 형성되어 있고, 이 관통공(18)의 내부에는 실리콘 재질로 이루어진 소음방지부재(20)가 채워져 있다.In addition, a plurality of cut through holes 18 are formed on the iron plate 12 in a predetermined shape, and the noise preventing member 20 made of a silicon material is filled in the through holes 18.

따라서, 작업자가 절삭장치에 구비된 절삽톱(10)을 고속회전시켜 암석이나 아스팔트와 같이 단단하고 강한 구조물을 작업설계에 맞게 절삭하면되는데, 이와 같이 절삭 과정중에 구조물과 절삭톱(10)의 간에 절삭마찰로 인하여 절삭톱(10)에 소음이 심하게 발생하게 된다.Therefore, the operator rotates the cutting saw 10 provided in the cutting device at a high speed to cut a hard and strong structure such as rock or asphalt according to the design of the work, and thus, between the structure and the cutting saw 10 during the cutting process. Due to cutting friction, noise is severely generated in the cutting saw 10.

이때, 상기 철판(12)에 삽입된 실리콘 재질의 소음방지부재(20)가 진동을 흡수 완화시킴으로써, 진동이 감소되어 원활한 절삭과 소음을 현저히 줄이게 되는 것이다.At this time, the noise prevention member 20 made of silicon material inserted into the iron plate 12 absorbs and mitigates vibration, thereby reducing vibrations, thereby significantly reducing smooth cutting and noise.

그러나 상기와 같은 소음방지용 절삭톱(10)은 우선, 절삭시에 절삭마찰열이전도되어 철판(12)의 온도가 300℃ ∼ 350℃의 고온으로 형성되는데, 이와 같이 철판(12)의 온도가 고온으로 형성되면 상기 철판(12)에 구비된 소음방지부재(20)는 융점이 150℃인 실리콘 재질로 이루어져 있어 상기 철판(12)에 형성되는 고온에 의해 융해되어 관통공(18)으로 부터 빠져나오게 되고, 이로 인하여 절삭톱(10)이 고온으로 형성시에는 소음방지를 할 수 없는 문제점이 있었다.However, the noise cutting saw 10 as described above, first, the cutting friction heat is transferred at the time of cutting to form the temperature of the iron plate 12 to 300 ℃ ~ 350 ℃ high temperature, the temperature of the iron plate 12 in this way When formed as a noise preventing member 20 provided in the iron plate 12 is made of a silicon material having a melting point of 150 ℃ to be melted by the high temperature formed in the iron plate 12 to escape from the through hole 18 As a result, when the cutting saw 10 is formed at a high temperature, there is a problem in that it is not possible to prevent noise.

따라서, 상기와 같이 소음방지부재(20)가 절삭톱(10)의 마찰열에 의해 융해되지 않도록 반드시 냉각수(예를들어 물)를 사용하여 절삭톱(10)의 온도를 소음방지부재(20)의 융점보다 낮추어야하는데, 이때 냉각수의 공급이 어렵거나 불가능한 장소에서는 소음방지용 절삭톱의 기능이 상실되는 문제점이 있었다.Therefore, the temperature of the cutting saw 10 is adjusted by using cooling water (for example, water) so that the noise preventing member 20 is not melted by the frictional heat of the cutting saw 10 as described above. It should be lower than the melting point, in which case the function of the noise-proof cutting saw is lost in a place where the supply of cooling water is difficult or impossible.

본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 절삭톱의 내부에 비교적 전성이 좋고 융점이 높은 소음방지부재를 내장시킴으로써, 마찰열에 의해 절삭톱이 고온으로 형성되더라도 소음방지부재가 융해됨이 없이 소음을 감소시킬 수 있고, 아울러 냉각수의 사용이 선택적이어서 절삭의 작업성을 한층 높일 수 있도록 한 소음방지용 절삭톱을 제공함에 그 목적이 있다.The present invention has been made in order to solve the above problems, the noise prevention member is melted even if the cutting saw is formed at a high temperature by frictional heat by embedding a relatively high malleability and high melting point noise prevention member inside the cutting saw. It is an object of the present invention to provide a noise-proof cutting saw that can reduce noise without using noise, and furthermore, the use of cooling water is optional, thereby further improving the workability of cutting.

상기와 같은 목적을 달성하기 위한 본 발명은 철판상에 일정한 형태를 이루며 다수개의 관통공이 형성된 소음방지용 절삭톱에 있어서, 상기 관통공에는 마찰열로 형성되는 고온 보다 융점이 높은 납,구리,아연,은,알루미늄 재질의 소음방지부재가 삽입된 구조로서, 마찰열에 의해 절삭톱이 고온으로 형성되더라도 소음방지부재가 융해됨이 없이 소음을 감소시킬 수 있는 점에 특징이 있다.The present invention for achieving the above object is a noise preventing cutting saw having a plurality of through holes formed in a certain shape on the iron plate, the through hole is a higher melting point than lead, copper, zinc, silver formed by frictional heat , A noise prevention member made of aluminum is inserted, and even if the cutting saw is formed at a high temperature by frictional heat, the noise prevention member is characterized in that noise can be reduced without melting.

첨부된 예시도면 도 3은 본 발명의 소음방지용 절삭톱을 나타낸 도면인 바,첨부된 예시도면 도 1 및 도 2와 동일한 참조번호는 동일한 부품을 표시하므로 이에 대한 설명은 생략하고 도 1 및 도 2와 상이한 점에 대해서만 설명하기로 한다.Figure 3 is a diagram showing a noise cutting saw according to the present invention, the same reference numerals are attached to the same reference numerals 1 and 2, the description of the same parts are omitted, so the description thereof will be omitted 1 and 2 Only different points from the above will be described.

첨부된 예시도면 도 3을 참조하면, 절삭톱(10)의 철판(12)상에는 레이저빔으로 가공하여 일정한 형태를 갖는 관통공(18)이 형성되어 있고. 이 관통공(18)의 내부에는 비교적 전성이 좋고 융점이 높은 비철금속의 소음방지부재(20)가 채워져 있는데, 이 소음방지부재(20)는 납,구리,아연,은,알루미늄의 재질로 이루어져 있다.3, the through hole 18 having a predetermined shape is formed on the iron plate 12 of the cutting saw 10 by machining with a laser beam. The through hole 18 is filled with a non-ferrous metal noise preventing member 20 having relatively high malleability and high melting point. The noise preventing member 20 is made of lead, copper, zinc, silver, and aluminum. .

상기와 같이 구성된 본 발명은 먼저, 절삽톱(10)을 고속회전시켜 구조물을 절삭시, 구조물과 절삭톱(10)의 간에 절삭마찰이 발생하면서 소음이 발생하게 되는데, 이때 첨부된 예시도면 도 3에 도시된 바와 같이 상기 절삭톱(10)의 철판(12)에는 납,구리,아연,은,알루미늄의 비철금속 재질로 이루어진 소음방지부재(20)가 진동을 흡수 완화시켜 소음을 방지하게 되는 것이다.According to the present invention configured as described above, first, when cutting the structure by cutting the cutting saw 10 at high speed, noise is generated while cutting friction occurs between the structure and the cutting saw 10, wherein the accompanying drawings Figure 3 As shown in the iron plate 12 of the cutting saw 10 is a noise preventing member 20 made of a non-ferrous metal material of lead, copper, zinc, silver, aluminum to absorb the vibration to prevent the noise.

그리고, 상기와 같이 절삭과정 중에는 구조물과의 마찰열이 절삭톱(10)의 철판(12)으로 전도되어 300℃ ∼ 350℃ 고온으로 형성되는데, 이때 비철금속으로 이루어진 소음방지부재(20)의 재질상 납의 융점은 400℃이고, 구리의 융점은 1080℃이며, 아연의 융점은 420℃이고, 은의 융점은 960℃ 이며 알루미늄의 융점은 660℃ 이므로 상기 철판(12)에서 형성되는 마찰온도 보다 현저히 높아 소음방지부재(20)가 융해됨이 없이 소음을 감소시킬 수가 있는 것이다.And, as described above, during the cutting process, frictional heat with the structure is conducted to the iron plate 12 of the cutting saw 10 to be formed at a high temperature of 300 ℃ ~ 350 ℃, wherein the material of the noise-proof member 20 made of non-ferrous metal The melting point is 400 ℃, the melting point of copper is 1080 ℃, the melting point of zinc is 420 ℃, the melting point of silver is 960 ℃ and aluminum is 660 ℃ melting point is significantly higher than the friction temperature formed in the iron plate 12 is noise prevention The noise can be reduced without the member 20 being melted.

따라서, 종래와 같이 실린콘 재질로 이루어진 소음방지부재(20)가 철판(12)에 형성되는 고온에 의해 융해되어 소음방지 기능이 상실됨이 없이 절삭톱(10)의 소음을 감소시킬 수 있는 것이다.Therefore, the noise preventing member 20 made of a silicon material is melted by the high temperature formed in the iron plate 12 as in the related art, thereby reducing the noise of the cutting saw 10 without losing the noise preventing function.

또한, 본 발명은 냉각수의 사용은 물론, 냉각수를 사용하지 않고도 절삭톱(10)의 소음방지기능이 정확히 발휘되어 냉각수의 사용에 대한 절삭작업의 불편함이 없이 소음방지를 효과적으로 대처할 수 있는 것이다.In addition, the present invention, as well as the use of the coolant, the noise prevention function of the cutting saw 10 can be accurately exhibited without using the coolant can effectively cope with the noise prevention without the inconvenience of cutting operation for the use of the coolant.

위와 같이 본 발명은 절삭톱의 내부에 비교적 전성이 좋고 융점이 높은 소음방지부재를 내장시킴으로써, 마찰열에 의해 절삭톱이 고온으로 형성되더라도 소음방지부재가 융해됨이 없이 소음을 감소시킬 수 있고, 아울러 냉각수의 사용이 선택적이어서 절삭의 작업성을 한층 높일 수 있는 효과가 있는 것이다.As described above, the present invention has a relatively malleable and high melting point noise prevention member inside the cutting saw, so that even if the cutting saw is formed at a high temperature by frictional heat, the noise prevention member can be reduced without melting, and Since the use of the coolant is optional, the workability of the cutting can be further improved.
