Description

절삭면의 표면조도 및 냉각효과가 우수한 절삭톱날{Cutting saw blade increased cooling effect and roughness of cutting surface}Cutting saw blade increased cooling effect and roughness of cutting surface

본 고안은 절삭톱날에 관한 것이며, 특히, 피삭제를 절삭하는 과정에서 발생하는 마찰열에 의해 연화되어 쉽게 변형되는 것을 방지하기 위해 냉각효과를 향상시키며 또한 절삭면의 표면조도를 향상시키기 위한 절삭톱날을 제공하는 데 있다.The present invention relates to a cutting saw blade, in particular, to improve the cooling effect to prevent softening and easy deformation by the frictional heat generated in the process of cutting the cutting blade and to improve the surface roughness of the cutting surface To provide.

일반적인 기계톱은 원형의 절삭톱날과 이를 회전시키는 모터를 포함한다. 모터에 의해 회전하는 절삭톱날을 피삭제에 가압하면 절삭톱날의 가장자리에 고정된 절삭날에 의해 피삭제가 절삭되면서 절단된다. 여기에서 절삭날은 다이아몬드 절삭날로서 티스(teeth)가 고정된다.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 while being cut by the cutting blade fixed to the edge of the cutting blade. Here, the cutting edge is a diamond cutting edge in which teeth are fixed.

도면에서, 도 1a는 종래 기술에 따른 절삭톱날의 평면도이고, 도 1b는 도 1a에 도시된 절삭톱날의 절삭날을 나타낸 상세도이다.In the drawings, FIG. 1A is a plan view of a cutting saw blade according to the prior art, and FIG. 1B is a detailed view showing the cutting edge 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 가장자리 원주를 따라 고정된 다이아몬드 절삭날(13)과, 원판형 생크(11)의 중심점에 형성된 센터홀(17)과, 다이아몬드 절삭날(13)과 센터홀(17)의 사이에 생크(11) 원주방향으로 일렬로 형성된 다수 개의 냉각홀(15)들 및, 센터홀(17)을 중심으로 생크(11)의 반지름방향으로 원주를 따라 형성된 다수 개의 그루브(18)들을 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 an edge circumference of the shank 11, and a disc shaped blade. A center hole 17 formed at the center point of the shank 11, a plurality of cooling holes 15 formed in a line in the circumferential direction of the shank 11 between the diamond cutting edge 13 and the center hole 17, The center hole 17 includes a plurality of grooves 18 formed along the circumference of the shank 11 in the radial direction.

이와 같은 절삭톱날(10)의 센터홀(17)에는 모터의 회전축이 고정되고, 모터의 회전력에 의해 생크(11)가 회전하면서 다이아몬드 절삭날(13)이 피삭제를 절삭한다. 여기에서 다이아몬드 절삭날(13)은 도 1b에 보이듯이 그루브(18)와 그루브(18)의 사이에 고정된 티스(teeth)(14)들로 이루어진다.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. The diamond cutting edge 13 here consists of teeth 14 fixed between the grooves 18 and the grooves 18 as shown in FIG. 1B.

일반적으로 다이아몬드 절삭날(13)은 석재 또는 콘크리트를 절단하는데 사용되는 톱날로서, 석재 또는 콘크리트와 같은 피삭제를 절삭하는 과정에서 고온의 마찰열이 발생한다.In general, the diamond cutting edge 13 is a saw blade used to cut stone or concrete, the high temperature friction heat is generated in the process of cutting the removal target such as stone or concrete.

절삭톱날(10)의 생크(11)는 이런 마찰열에 의해 과열된다. 특히 절삭깊이가 깊어져 냉각홀(15)이 절삭부 내부에 위치할 경우에 냉각홀(15)은 그 냉각기능을 거의 상실하여 마찰열에 의한 생크(11)의 온도는 급속히 상승하게 된다. 그로 인해 생크(11)는 연화되어 변형된다.The shank 11 of the cutting blade 10 is overheated by this frictional heat. In particular, when the depth of cut deepens and the cooling hole 15 is located inside the cutting part, the cooling hole 15 almost loses its cooling function and the temperature of the shank 11 due to frictional heat is rapidly increased. As a result, the shank 11 is softened and deformed.

한편, 앞에서 설명한 바와 같이 구성된 절삭톱날을 이용하여 석재를 절단할 시에 치핑(chipping)현상이 발생하여 석재의 절단면이 거칠어진다. 이와 같은 치핑은 다이아몬드 절삭날의 전체면적 당 티스가 차지하는 전체면적이 상대적으로 작기 때문에 발생한다.On the other hand, the chipping phenomenon occurs when the stone is cut using the cutting saw blade configured as described above, the cutting surface of the stone becomes rough. Such chipping occurs because the total area occupied by the teeth per total area of the diamond cutting edge is relatively small.

본 고안은 앞서 설명한 바와 같은 종래 기술의 문제점을 해결하기 위하여 제안된 것으로서, 절삭깊이가 깊어지더라도 냉각효과를 발현할 수 있고, 또한 절삭시에 치핑현상을 방지하여 우수한 표면조도를 갖는 절삭면이 형성되도록 구성된 절삭톱날을 제공하는 데 그 목적이 있다.The present invention is proposed in order to solve the problems of the prior art as described above, it is possible to express a cooling effect even if the depth of cut deep, and also to prevent the chipping phenomenon at the cutting surface having a good surface roughness It is an object to provide a cutting saw blade configured to be formed.

상기와 같은 목적을 달성하기 위한 본 고안은 원판형으로서, 그 중심에 관통공이 형성되고 원주방향으로 일렬로 제1 냉각홀들이 형성되며 반지름방향으로 원주를 따라 복수의 그루브들이 형성된 생크를 포함한 절삭톱날에 있어서, 상기 생크의 반지름방향으로 원주를 따라 적어도 한 열 이상 배열된 복수의 제2 냉각홀들과, 상기 그루브 한 개 당 그 양측에 각각 한 개씩 고정된 티스들을 포함하여 구성된 것을 기술적 특징으로 한다.The present invention for achieving the above object is a disk-shaped, cutting hole including a shank formed with a through-hole in the center and the first cooling holes are formed in a line in the circumferential direction and a plurality of grooves formed along the circumference in the radial direction The technical feature of the present invention includes a plurality of second cooling holes arranged in at least one row along the circumference in the radial direction of the shank, and teeth fixed to one side of each of the grooves. .

아래에서, 본 고안에 따른 절삭면의 표면조도 및 냉각효과가 우수한 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 excellent surface roughness and cooling effect according to the present invention will be described in detail.

도면에서, 도 2a는 본 고안의 한 실시예에 따른 절삭톱날의 평면도이며, 도 2b는 도 2a에 도시된 절삭톱날의 절삭날을 나타낸 상세도이다.In the drawings, Figure 2a is a plan view of a cutting blade according to an embodiment of the present invention, Figure 2b is a detailed view showing a cutting blade of the cutting saw blade shown in Figure 2a.

도 2a 및 도 2b에 도시된 바와 같이, 절삭톱날(100)은 원판형이며 중심에 센터홀(170)이 형성된 생크(110)와, 생크(110)의 가장자리 원주를 따라 고정된 다이아몬드 절삭날(130)과, 생크(110)의 가장자리에 그 원주방향으로 일렬로 형성된 제1 냉각홀(151)들과, 생크(110)의 센터홀(170)을 중심으로 90°의 간격으로 생크(110)의 반지름방향으로 배열된 복수의 제2 냉각홀(152)들 및, 생크(110)의 반지름방향으로 원주를 따라 형성된 복수의 그루브(180)들을 포함한다. 여기에서, 그루브(180)는 절삭시에 발생하는 슬러지(Sludge)를 원활하게 배출하기 위해 형성된 것이다.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 formed at the center thereof, and a diamond cutting edge fixed along an edge circumference of the shank 110. 130, the first cooling holes 151 formed in the circumferential direction at the edge of the shank 110, and the shanks 110 at intervals of 90 ° with respect to the center hole 170 of the shank 110. The plurality of second cooling holes 152 arranged in the radial direction of the plurality of grooves 180 formed along the circumference in the radial direction of the shank 110. Here, the groove 180 is formed to smoothly discharge the sludge generated during cutting.

이와 같이 구성된 절삭톱날(100)을 이용하여 피삭제를 절삭함에 있어서, 그 절삭깊이가 깊어져 제1 냉각홀(151)이 절삭부 내에 위치하여 회전하더라도, 제2 냉각홀(152)의 전부 또는 일부는 피삭제의 절삭부 외부에 위치함으로써, 외부에 위치한 제2 냉각홀(152)에 의해 생크(110)는 냉각된다.In cutting the erased object by using the cutting saw blade 100 configured as described above, even if the first cutting hole 151 rotates while the first cooling hole 151 is positioned in the cutting part, the whole or the second cooling hole 152 may be rotated. The part is located outside the cut portion of the erased portion, so that the shank 110 is cooled by the second cooling hole 152 located outside.

한편, 다이아몬드 절삭날(130)은 도 2b에 도시된 바와 같이 한 그루브(180) 당 양측에 2개의 티스(140)가 고정된다. 이런 티스(140)는 직사각형의 형상으로서 각 꼭지점이 라운드처리되어 절삭면의 표면조도를 향상시킨다.On the other hand, the diamond cutting edge 130 is fixed to two teeth 140 on both sides per groove 180, as shown in Figure 2b. The teeth 140 have a rectangular shape, and each vertex is rounded to improve the surface roughness of the cutting surface.

앞서 상세히 설명한 바와 같이, 본 고안의 절삭톱날은 제2 냉각홀들이 생크의 반지름방향으로 형성되어 있어, 피삭제의 절삭깊이가 깊어지더라도 제2 냉각홀의 전부 또는 일부가 대기 중에 노출되어 생크를 냉각시킨다.As described in detail above, in the cutting blade of the present invention, since the second cooling holes are formed in the radial direction of the shank, all or part of the second cooling holes are exposed to the air to cool the shank even when the depth of cut is deepened. Let's do it.

따라서, 절삭과정에서 발생하는 마찰열에 의해 생크가 연화되는 것을 효과적으로 방지함으로써, 절삭톱날이 휘거나 파괴되는 것을 방지할 수 있다는 장점이 있다.Therefore, by effectively preventing the shank from being softened by the frictional heat generated during the cutting process, there is an advantage that the cutting saw blade can be prevented from bending or breaking.

또한, 본 고안의 절삭톱날에서는 그루브 당 그 양측에 각각 티스들이 고정된다. 따라서 종래의 다이아몬드 절삭날에 비해 티스의 폭은 좁아지나 티스의 개수가 증가하고 티스 사이의 간격이 좁아짐에 따라, 다이아몬드 절삭날의 전체면적 당 티스의 전체면적이 상대적으로 넓어진다. 이런 구조를 갖는 절삭톱날을 이용하여 절삭하면, 절삭면의 표면조도 및 절삭성 또한 향상된다는 장점이 있다.In addition, in the cutting blade of the present invention, the teeth are fixed on both sides of each groove. Therefore, as compared with the conventional diamond cutting edge, the width of the teeth is narrowed, but as the number of teeth is increased and the spacing between the teeth is narrowed, the total area of the teeth per total area of the diamond cutting edge is relatively widened. When cutting using a cutting blade having such a structure, there is an advantage that the surface roughness and the machinability of the cutting surface is also improved.

이상에서 본 고안의 절삭면의 표면조도 및 냉각효과가 우수한 절삭톱날에 대한 기술사상을 첨부도면과 함께 서술하였지만, 이는 본 고안의 가장 양호한 실시예를 예시적으로 설명한 것이지 본 고안을 한정하는 것은 아니다.Although the technical concept of the cutting saw blade having excellent surface roughness and cooling effect of the cutting surface of the present invention has been described together with the accompanying drawings, this is illustrative of the best embodiments of the present invention and is not intended to limit the present invention. .
