Description

보강판 및 소음흡수판을 구비한 절삭톱날{Cutting saw blade with reinforcement plate and buffer plate}Cutting saw blade with reinforcement plate and buffer plate}

본 고안은 절삭톱날에 관한 것이며, 특히, 피삭제를 절삭하는 과정에서 발생하는 마찰열에 의해 연화되어 쉽게 변형되는 것을 방지함과 동시에 발생하는 소음을 감소하기 위해 보강판 및 소음흡수판을 구비한 절삭톱날을 제공하는 데 있다.The present invention relates to a cutting saw blade, in particular, cutting with a reinforcing plate and noise absorbing plate to reduce the noise generated at the same time to prevent the softening and easy deformation by the frictional heat generated in the process of cutting the removal. To provide a saw blade.

일반적인 기계톱은 원형의 절삭톱날과 이를 회전시키는 모터를 포함한다. 모터에 의해 회전하는 절삭톱날을 피삭제에 가압하면 절삭톱날의 외주에 고정된 절삭날에 의해 피삭제가 절삭되면서 절단된다. 여기에서 절삭날은 다이아몬드 절삭날 또는 티스(teeth)가 고정된 절삭날이 있다.Common saws include circular saw blades and motors that rotate them. When the cutting blade that is rotated by the motor is pressed against the cutting blade, the cutting blade is cut by the cutting blade fixed to the outer circumference of the cutting blade. The cutting edge here is a diamond cutting edge or a cutting edge fixed in teeth.

도면에서, 도 1a는 종래의 기술에 따른 절삭톱날의 평면도이고, 도 1b는 도 1a에 도시된 절삭톱날에 있어 직경방향(A-A')의 단면도이다.1A is a plan view of a cutting saw blade according to the prior art, and FIG. 1B is a sectional view in the radial direction A-A 'of the cutting saw blade shown in FIG. 1A.

도 1a 및 도 1b에 도시된 바와 같이, 절삭톱날(10)은 크게 원판형 생크(shank)(11)와, 생크(11)의 외주를 따라 고정된 다이아몬드 절삭날(13)과, 원판형 생크(11)의 중심점에 형성된 센터홀(17)을 포함한다.As shown in FIGS. 1A and 1B, the cutting saw blade 10 has a large disc shaped shank 11, a diamond cutting edge 13 fixed along the outer circumference of the shank 11, and a disc shaped shank. And a center hole 17 formed at the center point of (11).

그리고 절삭톱날(10)의 센터홀(17)에는 모터의 회전축이 고정되고, 모터의 회전력에 의해 생크(11)가 회전하면서 다이아몬드 절삭날(13)이 피삭제를 절삭한다.The rotating shaft of the motor is fixed to the center hole 17 of the cutting saw blade 10, and the diamond cutting blade 13 cuts the erased portion while the shank 11 rotates by the rotational force of the motor.

일반적으로 다이아몬드 절삭날이 고정된 절삭톱날은 석재 또는 콘크리트를 절단하는데 사용되는 톱날로서, 석재 또는 콘크리트와 같은 피삭제를 절삭하는 과정에서 고온의 마찰열이 발생한다.In general, a cutting saw blade having a fixed diamond cutting edge is a saw blade used to cut stone or concrete, and high-temperature friction heat is generated in the process of cutting a target such as stone or concrete.

도 1a 및 도 1b에 도시된 바와 같은 단층(single layer) 절삭톱날(10)은 피삭제 절삭시에 발생하는 마찰열에 의해 생크(11)가 쉽게 과열되어 변형된다.The single layer cutting saw blade 10 as shown in FIGS. 1A and 1B deforms the shank 11 easily by overheating due to frictional heat generated during the cutting.

한편 절삭톱날(10)의 다이아몬드 절삭날(13)은 그 경도(hardness)가 큼에 따라 상대적으로 깨지기 쉬운(brittle) 특성을 갖고 있다. 따라서, 생크(11)가 연화되면 다이아몬드 절삭날은 쉽게 파괴되는 단점이 있다.On the other hand, the diamond cutting edge 13 of the cutting blade 10 has a relatively brittle characteristic as the hardness (hardness) is large. Therefore, the diamond cutting edge is easily broken when the shank 11 is softened.

또한, 다이아몬드 절삭날이 피삭제와 접하여 절삭하는 과정에서 상당한 소음이 발생하는데, 종래의 절삭톱날에는 이런 소음을 흡수하는 소음흡수기능이 없어 절삭시에는 절삭톱날이 소음공해원으로 작용한다.In addition, a significant noise is generated in the process of cutting the diamond cutting edge in contact with the erased, the conventional cutting saw blade does not have a noise absorbing function that absorbs this noise, the cutting saw blade acts as a noise source during cutting.

본 고안은 앞서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 제안된 것으로서, 생크의 중심부를 보강하여 마찰열에 의한 변형을 방지함과 동시에 피삭제와 마찰에 의해 발생하는 소음을 완충하는 기능을 갖는 보강판 및 소음흡수판을 구비한 절삭톱날을 제공하는 데 그 목적이 있다.The present invention is proposed to solve the problems of the prior art as described above, reinforcement having the function of reinforcing the center of the shank to prevent deformation caused by frictional heat and at the same time cushion the noise generated by the removal and friction. It is an object of the present invention to provide a cutting blade having a plate and a sound absorbing plate.

상기와 같은 목적을 달성하기 위한 본 고안은 원판형으로서, 그 중심에 관통공이 형성되고 외주를 따라 절삭날이 고정된 생크를 포함한 절삭톱날에 있어서, 상기 생크의 관통공과 동일한 크기의 중공이 형성되며 상기 생크의 관통공과 상기 중공이 연통되도록 상기 생크의 일면 또는 양면에 고정되는 소음흡수판과, 상기 소음흡수판의 중공과 동일한 중공이 형성되며 상기 소음흡수판의 중공과 연통되도록 상기 소음흡수판에 고정되는 보강판을 포함하여 구성된 것을 기술적 특징으로 한다.The present invention for achieving the above object is a disk-shaped, in the cutting blade including a shank, the through-hole is formed in the center and the cutting edge is fixed along the outer periphery, hollow of the same size as the through-hole of the shank is formed The sound absorbing plate is fixed to one side or both sides of the shank so that the through-hole and the hollow of the shank communicate with each other, and the same hollow as the hollow of the sound absorbing plate is formed and the noise absorbing plate to communicate with the hollow of the sound absorbing plate. It is characterized by a technical feature including a reinforcing plate to be fixed.

또한, 본 고안의 상기 소음흡수판과 상기 보강판에는 상기 생크의 관통공과 동일한 관통공이 형성되어 상기 생크의 관통공과 연통된다.In addition, the noise absorbing plate and the reinforcing plate of the present invention is formed through the same through hole as the through hole of the shank is in communication with the through hole of the shank.

바람직하게는 상기 소음흡수판은 강보다 상대적으로 연성이 좋은 구리, 아연, 황동, 청동 중에 어느 한 재질이다.Preferably, the noise absorbing plate is made of any one of copper, zinc, brass, and bronze, which is relatively softer than steel.

보다 바람직하게는 상기 보강판은 강철판 또는 열처리강판이다.More preferably, the reinforcing plate is a steel sheet or heat treated steel sheet.

아래에서, 본 고안에 따른 보강판 및 소음흡수판을 구비한 절삭톱날의 양호한 실시예를 첨부한 도면을 참조로 하여 상세히 설명하겠다.In the following, with reference to the accompanying drawings a preferred embodiment of a cutting blade having a reinforcing plate and a sound absorbing plate according to the present invention will be described in detail.

도면에서, 도 2a는 본 고안의 한 실시예에 따른 절삭톱날의 평면도이고, 도 2b는 도 2a에 도시된 절삭톱날에 있어 직경방향(B-B')의 단면도이다.In the drawings, FIG. 2A is a plan view of a cutting blade according to one embodiment of the present invention, and FIG. 2B is a cross-sectional view in the radial direction B-B 'of the cutting blade shown in FIG. 2A.

도 2a 및 도 2b에 도시된 바와 같이, 절삭톱날(100)은 원판형이며 센터홀(170)이 형성된 생크(110)와, 상기 생크(110)의 중심부 일면에 고정되며 중심에 중공(151)이 형성된 보강판(150)과, 상기 보강판(150)과 생크(110)의 사이에 위치하는 소음흡수판(140)을 포함한다.As shown in FIGS. 2A and 2B, the cutting saw blade 100 has a disc shape and a shank 110 having a center hole 170, and is fixed to one surface of a central portion of the shank 110 and has a hollow 151 at a center thereof. The formed reinforcement plate 150, and the sound absorption plate 140 is located between the reinforcement plate 150 and the shank 110.

이런 소음흡수판(140)은 생크(110)의 직경보다 작은 외경과 센터홀(170)의 직경과 동일한 내경의 중공(141)을 가지며 생크(110)의 일면 중심에 고정된다. 보강판(150)은 이런 소음흡수판(140)과 동일한 형상으로서, 그 중심에 중공(151)이 형성되며 소음흡수판(140)의 일면에 고정된다. 그리고 모터의 회전축은 생크(110)의 센터홀(170)과 소음흡수판(140)의 중공(141) 및 보강판(150)의 중공(151)을 관통하여 고정된다. 여기에서, 보강판(150)은 강철판 또는 열처리강판이며, 소음흡수판(140)은 보강판(150)보다 연성이 좋은 구리, 아연, 황동 및 청동 등의 재질로 구성되는 것이 바람직하다.The noise absorbing plate 140 has an outer diameter smaller than the diameter of the shank 110 and a hollow 141 having the same inner diameter as the diameter of the center hole 170 and is fixed to the center of one surface of the shank 110. The reinforcement plate 150 has the same shape as the noise absorbing plate 140, and a hollow 151 is formed at the center thereof and is fixed to one surface of the sound absorbing plate 140. In addition, the rotating shaft of the motor is fixed through the center hole 170 of the shank 110 and the hollow 141 of the noise absorbing plate 140 and the hollow 151 of the reinforcing plate 150. Here, the reinforcement plate 150 is a steel plate or heat-treated steel sheet, the noise absorption plate 140 is preferably made of a material such as copper, zinc, brass and bronze having a better ductility than the reinforcement plate 150.

이와 같이 구성된 본 고안의 절삭톱날을 이용하여 피삭제를 절삭함에 있어서, 생크(110)의 외주를 따라 고정된 다이아몬드 절삭날(130)은 피삭제를 절삭한다.In cutting the to-be-deleted using the cutting saw blade of the present invention configured as described above, the diamond cutting edge 130 fixed along the outer periphery of the shank 110 to cut the to-be-deleted.

다이아몬드 절삭날(130)이 피삭제를 절삭함에 따라 발생하는 마찰열은 생크(110)를 연화시키지만, 생크(110)의 중심부에 보강판(150)이 용접고정됨으로써, 연화에 따른 변형을 방지한다. 한편, 마찰소음은 생크(110)를 통해 전달되는데, 소음이 생크(110)에서 보강판(150)으로 전달되는 과정에서 중간에 위치한 소음흡수판(140)에 의해 소음이 흡수된다. 따라서, 석재 또는 콘크리트구조물을 절삭함에 따라 발생하는 소음은 감소된다.The frictional heat generated as the diamond cutting edge 130 cuts the erased material softens the shank 110, but the reinforcement plate 150 is welded to the center of the shank 110 to prevent deformation due to softening. On the other hand, the friction noise is transmitted through the shank 110, the noise is absorbed by the noise absorbing plate 140 located in the middle of the noise is transferred from the shank 110 to the reinforcing plate 150. Thus, noise generated by cutting the stone or concrete structure is reduced.

한편, 앞에서 설명한 본 고안의 절삭톱날(100)은 생크(110)의 일면에 소음흡수판(140)과 보강판(150)이 용접고정된 것으로 설명하였으나, 생크의 양면에 소음흡수판과 보강판이 용접고정되어 생크를 중심으로 상호 대칭되게 배치될 수 있다. 이와 같이 생크의 양면에 소음흡수판과 보강판이 고정되면 생크의 강도 및 소음감소율은 앞에서 설명한 절삭톱날보다 우수하게 된다.On the other hand, the cutting saw blade 100 of the present invention has been described that the noise absorbing plate 140 and the reinforcement plate 150 is fixed to one side of the shank 110, the sound absorbing plate and the reinforcement plate on both sides of the shank The welding may be fixed and arranged symmetrically with respect to the shank. As such, when the noise absorbing plate and the reinforcing plate are fixed to both sides of the shank, the strength and noise reduction rate of the shank are superior to those of the cutting saw blade described above.

앞서 상세히 설명한 바와 같이, 본 고안의 절삭톱날은 절삭과정에서 마찰열에 의해 생크가 연화되는 것을 보강판으로 보강함으로써, 휨을 방지한다는 장점이 있다.As described in detail above, the cutting saw blade of the present invention has an advantage of preventing bending by reinforcing the shank is softened by frictional heat in the cutting process with a reinforcing plate.

또한, 본 고안의 절삭톱날은 생크와 보강판의 사이에 소음흡수판이 위치하여 생크를 통해 전달되는 소음을 감소시킴으로써, 절삭톱날을 이용하여 절삭작업을 수행함에 따라 발생하는 소음공해를 감소시킬 수 있다는 장점이 있다.In addition, the cutting saw blade of the present invention is located between the shank and the reinforcement plate to reduce the noise transmitted through the shank, it is possible to reduce the noise pollution generated by the cutting operation using the cutting saw blade There is an advantage.

이상에서 본 고안의 보강판 및 소음흡수판을 구비한 절삭톱날에 대한 기술사상을 첨부도면과 함께 서술하였지만, 이는 본 고안의 가장 양호한 실시예를 예시적으로 설명한 것이지 본 고안을 한정하는 것은 아니다.Although the technical idea of the cutting saw blade having the reinforcing plate and the sound absorbing plate of the present invention has been described together with the accompanying drawings, this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
