Description
본 고안은 건축 및 토목용 아스팔트, 아스콘, 그린 콘크리트 등의 석재 절삭물을 절단가공시 사용하는 커팅휠의 절삭팁구조에 관한 것으로서, 좀더 상세하게는 높이 차를 갖는 다단의 절삭 단차면을 형성하는 절삭날을 방사상으로 양측방에 교차 대향되게 구비함에 의해 절삭물의 절삭가공시 마찰면적을 줄여 마찰력 감소에 의한 부하경감과 그 절삭능력 향상을 동시에 이룸은 물론 견고성을 제공하는 커팅휠의 절삭팁구조에 관한 것이다.The present invention relates to a cutting tip structure of a cutting wheel that is used for cutting and processing stone cutting materials such as asphalt, asphalt concrete, and green concrete for building and civil engineering, and more specifically, to form a multi-stage cutting step surface having a height difference. The cutting edges of the cutting wheels are radially opposite to each other to reduce the friction area during cutting of the cutting material, reducing the load by reducing the friction force and improving the cutting capacity. It is about.
일반적으로 건축 및 토목용 아스팔트, 아스콘, 그린 콘크리트 등의 석재 절삭물을 절단가공시에 사용되는 커팅휠은 도 1에 도시된 바와 같이 코어판(10)의 외주면으로 다이아몬드 및 금속분말을 혼재하여 소결시킨 절삭팁(15)을 용착구성하여 이루어진다.In general, a cutting wheel used for cutting and cutting stone cutting materials such as asphalt, asphalt concrete, and green concrete for construction and civil engineering is sintered by mixing diamond and metal powder on the outer circumferential surface of the core plate 10 as shown in FIG. It is made by welding the cutting tip 15.
이러한 커팅휠에 있어서, 상기 코어판(10)에 용착되는 절삭팁(15)의 구조에 따라 커팅휠이 장착되는 절단기의 부하 경감 및 석재 절단능력이 좌우된다.In such a cutting wheel, depending on the structure of the cutting tip 15 welded to the core plate 10, the load reduction and the stone cutting ability of the cutting machine is equipped with the cutting wheel is determined.
그러나, 상기한 커팅휠의 경우에는 절삭팁(15)이 단순히 일정 두께로만 형성되어 있어, 석재 절단가공시 석재와의 마찰면적이 넓어 마찰력이 증가되고, 이로 인해 절단기의 부하가 크고, 상기한 마찰력에 의해 그 절단능력도 저하되는 구조적 문제를 갖고 있었다.In the case of the cutting wheel, however, the cutting tip 15 is simply formed to have a predetermined thickness, so that the friction area with the stone is wide when the stone cutting is performed, thereby increasing the frictional force. There was a structural problem in which the cutting ability was also lowered.
이러한 문제점을 해결하고자한 다양한 구조의 커팅휠이 개시된바 있는데, 도 2에서는 절삭팁(15)의 양측면으로 다수의 요홈부(16)를 형성하여 상기 요홈부(16)에 의해 석재와의 절단 마찰력을 감소시키고자 하였으나, 석재 절단가공시에 생기는 석재의 가루가 상기 요홈부(16)에 채워지면서 석재와의 절단 마찰면적이 커져 마찰력증가로 인해 부하가 크게되고, 그 절삭능력도 저하되는 문제를 여전히 갖게 되었고,Various cutting wheels have been disclosed to solve this problem. In FIG. 2, a plurality of grooves 16 are formed on both sides of the cutting tip 15 to cut frictional force with the stone by the grooves 16. However, as the powder of the stone generated during the stone cutting process is filled in the grooves 16, the cutting friction area with the stone increases, so that the load increases due to the increased frictional force, and the cutting ability also decreases. I still have it,
또한, 도 3에서는 상기 절삭팁(15)의 양측면으로 경사면(17)을 형성하고, 이에 요홈부(17')를 형성하였다.In addition, in FIG. 3, the inclined surfaces 17 are formed on both sides of the cutting tip 15, and the recesses 17 ′ are formed therein.
이는 상기 절삭팁(15)의 양측면이 경사면(17)으로 형성되어 석재와의 절단 마찰면적을 작게 형성할 수 있기 때문에 절삭에 따른 부하를 다소 감소시킬 수는 있었으나, 상기 절삭팁(15)의 경사면(17)으로는 충분한 절삭면적을 확보할 수 없어 그 절삭능력이 크게 저하됨은 물론 상기 경사면(17)의 모서리부분의 마모가 심하여 그 사용수명을 단축시키게 되는 문제를 갖게 되었다.This is because both sides of the cutting tip 15 is formed as the inclined surface 17 can form a small cutting friction area with the stone, but the load due to the cutting can be somewhat reduced, but the inclined surface of the cutting tip 15 In (17), a sufficient cutting area cannot be secured, and the cutting capacity thereof is greatly lowered, and the edge portion of the inclined surface 17 is severely worn, resulting in a problem of shortening its service life.
본 고안은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 안출된 것으로서, 석재 절삭물의 절단 가공시 마찰면적에 따른 마찰력을 어느 정도 감소시켜 절삭에 따른 부하를 경감시킴과 동시에 절삭력 향상을 이루므로 절삭작업을 효율적으로 행하는데 그 목적이 있다.The present invention was devised to solve all the problems of the prior art, which reduces the frictional force according to the friction area to a certain extent when cutting the stone cutting to reduce the load due to the cutting and at the same time improves the cutting work The purpose is to efficiently perform the
또한, 본 고안은 전체적인 두께를 어느 정도 확보함에 따른 견고성을 우수하게 제공하는데 그 목적이 있다.In addition, the present invention has an object to provide excellent robustness by securing the overall thickness to some extent.
이러한 본 고안의 목적은 절삭팁의 양측면에 높이 차를 갖도록 직각 단차지게 형성되는 다단의 절삭 단차면을 갖는 다수의 절삭날을 방사상으로 상호 교차되게 대향 형성하여서, 상기 절삭 단차면이 종래의 절삭날에 비해 효율적인 마찰면적을 형성하므로 마찰면적에 따른 마찰력 저하로 측면 부하를 감소시킴과 동시에 그 절삭능력 향상을 이루고, 상기 절삭 단차면을 교차되게 대향 형성하여 어느 정도의 두께를 확보하므로 우수한 견고성을 제공하여 달성된다.The object of the present invention is to form a plurality of cutting edges having a plurality of cutting step surface having a multi-stage cutting step surface formed at right angles to have a height difference on both sides of the cutting tip, so that the cutting step surface is a conventional cutting edge Compared with the friction area, it reduces the side load by reducing the frictional force and improves the cutting capacity. Also, the cutting step surface is formed to face each other to secure a certain thickness, thereby providing excellent rigidity. Is achieved.

이하, 상기한 본 고안의 목적을 달성하기 위한 바람직한 실시예를 첨부도면을 참조하여 구체적으로 살펴보기로 한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment for achieving the object of the present invention will be described in detail.
즉, 본 고안은 도 4 내지 6에 도시된 바와 같이, 원판형의 코어판(10)과, 이 코어판의 외주연에 일부분이 중첩되게 포개지도록 소결성형한 절삭팁(15)으로 구성된 커팅휠에 있어서, 상기 절삭팁(15)의 양측면에는 높이 차를 갖도록 직각 단차지게 형성되는 다단의 절삭 단차면(21)(22)(23)을 갖는 다수의 절삭날(20)(20')을 상기 코어판(10)의 중심에서 회전방향으로 소정각도의 경사를 이루도록 형성하고, 상기 일측의 절삭날(20) 사이의 위치로 대향측의 절삭날(20')이 교차되게 위치하도록 형성하도록 이루어진다.That is, the present invention, as shown in Figures 4 to 6, the cutting wheel consisting of a disk-shaped core plate 10, and a cutting tip 15 sintered and molded so that a portion overlaps the outer periphery of the core plate. In the cutting tip 15, a plurality of cutting edges (20, 20 ') having a plurality of cutting step surfaces (21, 22, 23) are formed at right angles to have a height difference on both sides of the cutting tip (15). It is formed to form an inclination of a predetermined angle in the rotational direction in the center of the core plate 10, and is formed so as to cross the cutting edge 20 'of the opposite side to the position between the cutting edge 20 of the one side.
각 절삭날(20)의 사이로 가장 낮은 절삭 단차면(23)보다도 깊이 요설된 요홈부(25)를 형성하여 이루어진다.It is formed by forming the concave groove 25 deeper than the lowest cutting step surface 23 between each cutting edge 20.
미설명부호로서, 25는 각 절삭날(20)(20')의 사이로 형성된 요홈부를 나타내는 것이다.As the reference numeral 25, reference numerals denote recesses formed between the cutting edges 20 and 20 '.
이와 같이 구성된 본 고안은 미도시된 절단기에 설치되어 고속으로 회전하면서 절단물 즉, 석재 또는 이와 유사한 대상물을 절단하게 된다.The present invention configured as described above is installed in a cutter (not shown) to rotate at high speed to cut a cut, that is, a stone or a similar object.
이를 구체적으로 설명하면, 처음에는 상기 절삭팁(15)의 원주상에 방사상으로 다수 형성된 절삭날(20)(20')의 가장 높은 위치의 절삭 단차면(21)에 의해 절삭물의 절삭이 진행되면서 점점 깊숙이 절단하게 된다.In detail, at first, cutting of the cutting material is performed by the cutting step surface 21 at the highest position of the cutting edges 20 and 20 'radially formed on the circumference of the cutting tip 15. I will cut deeper and deeper.
이때, 상기 절삭 단차면(21)에 의한 절단과정시 상기 절삭 단차면(21)은 소정의 마찰면적을 형성하되, 종래 평면 형태의 절삭팁에 따른 전체적인 접촉 마찰면적에 비해서는 작은 부분접촉을 갖게 되므로 절단물과의 마찰력을 어느 정도 줄여 장치의 부하 절감을 이루게 되고,At this time, the cutting step surface 21 during the cutting process by the cutting step surface 21 forms a predetermined friction area, but has a small partial contact compared to the overall contact friction area according to the cutting tip of the conventional flat form Therefore, the frictional force with the cutting part is reduced to some extent, thereby reducing the load on the device.
이와 동시에 상기 절삭단차면(21)은 종래 경사면 형태의 절삭팁에 따른 선접촉에 비해서는 어느 정도 절단물과의 절단면적을 형성하므로 그 절삭능력은 향상시키게 되는 것이다.At the same time, the cutting step surface 21 is to form a cutting area with the cutting to some extent compared to the line contact according to the cutting tip of the conventional inclined surface shape is to improve the cutting capacity.
다시 말해, 상기 절삭 단차면(21)에 의한 절단가공은 효율적인 마찰면적으로 마찰력감소에 따른 부하절감과 절삭면적확보에 따른 절삭능력 향상을 동시에 이루므로 최적의 절삭 상태로 석재의 절단을 행하게 되는 것이다.In other words, the cutting process by the cutting step surface 21 is to cut the stone in the optimum cutting state because at the same time the effective friction area to reduce the load due to the frictional force and to improve the cutting capacity according to securing the cutting area. .
상기와 같이 절삭날(20)(20')의 절삭 단차면(21)에 의한 절삭과정을 행하다가 상기 절삭 단차면(21)이 마모되면 계속적으로 인접하는 다음의 절삭 단차면(22)에 의한 절삭과정이 진행된다.As described above, when the cutting step surface 21 of the cutting edges 20 and 20 'is cut, and the cutting step surface 21 wears, the next cutting step surface 22 continuously adjoins. The cutting process proceeds.
이때, 상기 절삭 단차면(21),(22)은 직각의 단차를 이루도록 형성되어 있어 처음의 절삭 단차면(21)이 마모됨과 함께 계속적인 다음 절삭 단차면(22)에 의한 절삭가공의 진행이 가능하게 된다.At this time, the cutting step surface (21), 22 is formed to form a step of the right angle so that the first cutting step surface 21 is worn and the progress of the cutting by the next cutting step surface 22 is continued It becomes possible.
이와 같은 인접한 절삭 단차면(22)에 의한 절삭가공시에는 상기 처음의 절삭 단차면(21)에 비해서 절삭물과의 마찰면적이 커지면서 절삭 마찰력에 의한 부하가 다소 증가되지만, 반면에 그 절삭능력은 증가되는 상태로 절삭과정을 수행하게 된다.When cutting by the adjacent cutting step surface 22 as described above, the load by the cutting friction force increases slightly as the friction area with the workpiece increases compared to the first cutting step surface 21, while the cutting capacity is increased. The cutting process is performed in an increasing state.
그러나, 이 경우에도 전술한 종래의 평면 형태의 절삭팁에 비해서는 절단물과의 마찰력을 어느 정도 줄여 장치의 부하를 절감함과 동시에 경사면 형태의 절삭팁에 비해서는 절단물과의 절단면적이 넓어 절삭능력이 우수하게 된다.However, even in this case, the cutting force of the device is reduced by reducing frictional force with the cutting to some extent as compared to the conventional cutting tools of the planar shape, and the cutting area with the cutting material is wider than that of the inclined cutting tip. Cutting ability is excellent.
이와 같이하여 상기 절삭날(20)(20')의 단차지게 형성되는 절삭 단차면(21)(22)(23)이 차례로 마모되면서 상기 절삭물을 효과적으로 절삭하게 되는 것이다.As such, the cutting step surfaces 21 and 22 and 23 that are formed to be stepped on the cutting edges 20 and 20 'are sequentially worn, thereby effectively cutting the cuttings.
한편, 상기 절삭날(20)에 의한 절삭과정중에 상기 절삭물에서 나오는 석분은 상기 절삭날(20)(20')의 사이로 형성된 요홈부(25)로 배출되게 된다.On the other hand, the stone powder coming out of the cutting during the cutting process by the cutting edge 20 is discharged to the groove portion 25 formed between the cutting edge 20, 20 '.
또한, 상기한 절삭날(20)(20')은 코어판(10)의 중심에서 회전방향으로 소정각도 경사를 이루도록 형성하므로서 상기 절삭날(20)이 절삭물과의 절삭에 대한 저항을 줄이게 되므로 그 절삭능력을 배가시키게 되고,In addition, since the cutting edges 20 and 20 'are formed to be inclined at a predetermined angle in the rotational direction from the center of the core plate 10, the cutting edges 20 reduce resistance to cutting with the cuttings. Double the cutting capacity,
또한, 상기한 절삭날(20)(20')은 일측의 절삭날(20) 사이 위치로 대향측의 절삭날(20')이 위치하도록 교차되게 대향 형성하여서 상기 요홈부(25)가 위치하는 부분의 두께를 어느 정도 확보함으로서 응력집중에 의해 상기 요홈부(25) 파손을 최소화하게 되는 것이다.In addition, the cutting edges 20 and 20 'are formed to face each other so that the cutting edges 20' on the opposite side are positioned to be positioned between the cutting edges 20 on one side so that the recess 25 is located. By securing the thickness of the portion to some extent it is to minimize the breakage of the groove portion 25 by stress concentration.
이상에서 상세히 살펴본 바와 같이 본 고안은 절삭팁에 높이 차를 갖는 다단의 단차를 이루는 절삭 단차면을 갖는 절삭날에 의해 효율적인 절삭면적을 제공하므로 절삭물과의 마찰면적에 따른 마찰력 감소와, 그에 따른 장치의 부하경감을 이룸과 동시에 상기 절삭면적에 따른 절삭능력 향상을 이루면서 절삭물의 절삭효율을 극대화시키게 되고,As described in detail above, the present invention provides an efficient cutting area by a cutting edge having a cutting step surface that forms a multi-step step with a height difference on the cutting tip, thereby reducing frictional force according to the friction area with the cutting material, and While reducing the load of the device and at the same time improving the cutting capacity according to the cutting area to maximize the cutting efficiency of the cutting,
또한, 상기 절삭날이 코어판의 중심에서 회전방향으로 소정각도 경사를 이루므로 절삭물과의 절삭에 대한 저항 감소에 따른 절삭능력의 배가와, 상기 절삭날을 코어판을 중심으로 대향되게 교차 형성하여 어느 정도의 두께 확보로 인한 견고성을 극대화하는 효과를 제공하게 되는 것이다.In addition, since the cutting edge is inclined at a predetermined angle in the rotational direction from the center of the core plate, the cutting capacity is doubled due to the decrease in resistance to cutting with the cutting material, and the cutting edge is formed to cross the core plate so as to face the core plate. It is to provide the effect of maximizing the robustness by securing a certain thickness.
