Description

절삭휠용 회전판의 강도 보강 장치 {Device for reinforcing the shank of cutting wheel}Strength reinforcing device for rotating wheels for cutting wheels {Device for reinforcing the shank of cutting wheel}

본 고안은 경질재료절단용 절삭휠의 몸체를 이루어 고속회전되는 원판형상의 회전판에 관한 것으로, 특히 회전판의 외표면에 다수개의 강도보강수단을 일체로 형성하여 절단작업과정에서 발생하는 변형손상을 방지시킬 수 있도록 된 절삭휠용 회전판의 강도 보강 장치에 관한 것이다.The present invention relates to a disk-shaped rotating plate that rotates at a high speed by forming a body of a cutting wheel for cutting a hard material, and in particular, a plurality of strength reinforcing means are integrally formed on the outer surface of the rotating plate to prevent deformation damage occurring during a cutting operation. It relates to a strength reinforcing device of the rotary plate for a cutting wheel that can be made.

일반적으로, 절삭휠(cutting wheel)은, 돌이나 금속과 같은 경질재료를 절단 또는 절삭하는 과정에서 이용되는 원판형상의 회전체로서, 이러한 절삭휠은 금속재질로 성형된 원판형상의 회전판(shank)과, 이 회전판의 둘레면을 따라 부착된 절삭날(blade)로 구성되어 외관을 이룬다.In general, a cutting wheel is a disk-shaped rotating body used in the process of cutting or cutting a hard material such as stone or metal, and the cutting wheel is a disk-shaped shank formed of a metal material. And a cutting blade (blade) attached along the circumferential surface of the rotating plate to form an appearance.

즉, 도 1에 도시된 바와 같이, 절삭휠(1)은, 원판형상으로 형성되어 몸체중심에 축공(11)이 형성됨은 물론 둘레면에 관통된 다수개의 흡수공(12)을 사이에두고 접합돌기(13)가 연속형성된 회전판(10)과, 회전판(10)의 접합돌기(13)에 레이져용접을 통해 접합된 다수개의 절삭날(20)로 구성되어 있다.That is, as shown in Figure 1, the cutting wheel 1 is formed in the shape of a disk, the shaft hole 11 is formed in the center of the body, as well as bonded through a plurality of absorption holes 12 penetrated through the circumferential surface. The projection 13 is composed of a rotating plate 10 which is continuously formed, and a plurality of cutting edges 20 joined to the joining projection 13 of the rotating plate 10 through laser welding.

따라서, 경질재료절삭장치(미도시)를 이루는 회전축에 축공(11)을 매개로하여 절삭휠(1)을 장착한 상태에서, 모우터(미도시)를 작동시키게 되면, 회전판(10)의 둘레면을 따라 레이져용접을 통해 접합되어있던 절삭날(20)들이 고속으로 회전하면서, 경질재료를 절단 또는 절삭하게 되는 것이다.Therefore, when the motor (not shown) is operated in the state in which the cutting wheel 1 is mounted on the rotating shaft forming the hard material cutting device (not shown) via the shaft hole 11, the circumference of the rotating plate 10 Cutting edges 20, which are joined together by laser welding along the surface, rotate or rotate at high speed, thereby cutting or cutting hard materials.

그런데, 회전판(10)의 둘레면에 레이져용접을 통해 절삭날(20)이 접합되어진 통상적인 절삭휠(1)의 경우, 회전판(10)의 외표면에 어떠한 강도보강수단도 형성되지 않아, 예컨대 경질재료를 절단하는 과정에서 손쉽게 열적으로 변형이 발생됨은 물론 진동현상으로 인해 소음이 발생되는 문제점이 있었다.By the way, in the case of the conventional cutting wheel 1 in which the cutting edge 20 is bonded to the circumferential surface of the rotating plate 10 by laser welding, no strength reinforcing means is formed on the outer surface of the rotating plate 10, for example. In the process of cutting hard materials, there is a problem that noise is generated due to vibration as well as thermal deformation easily.

또한, 회전판(10)이 열적으로 변형되어 진동이 발생되는 경우, 경질재료의 절단면을 거칠게 하여 절단품질을 저하시키게 될 뿐만 아니라, 경질재료의 치수오차를 유발하여 정밀한 절삭작업이 불가능하게 됨은 물론 절삭장치의 내구성을 저하시켜 수명을 단축시키게 되는 문제점이 있었다.In addition, when the rotating plate 10 is thermally deformed and vibration is generated, not only the cutting surface of the hard material is roughened, thereby lowering the cutting quality, but also causing the dimensional error of the hard material, thereby making it impossible to precisely cut the cutting. There is a problem in that the durability of the device is reduced to shorten the life.

이에, 본 고안은 상기한 바와 같은 제문제점을 해결하기 위하여 안출된 것으로서, 회전판과 절삭날이 레이져용접을 통해 접합되어진 통상적인 절삭휠의 경우에, 회전판의 외표면을 외표면을 따라 강도보강수단이 형성되게 하여, 절단작업과정에서 발생하는 변형손상을 방지시킬 수 있도록 된 절삭휠용 회전판의 강도 보강 장치를 제공하는 데에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and in the case of a conventional cutting wheel in which the rotating plate and the cutting edge are joined by laser welding, the outer surface of the rotating plate is strengthened along the outer surface. It is an object of the present invention to provide an apparatus for reinforcing strength of a rotating plate for a cutting wheel, which can be formed to prevent deformation damage occurring during a cutting operation.

상기한 바의 목적을 달성하기 위한 본 고안은, 강재질로 성형되어진 원판형상의 회전판과, 이 회전판의 둘레면에 레이져용접을 통해 접합된 다수개의 절삭날로, 절삭휠의 외관을 이루게 되는 통상적인 절삭휠의 강도보강장치를 형성함에 있어서, 회전판의 외표면에, 절삭휠의 고속회전과정에서 발생하는 진동을 흡수하여 내구성을 향상시킴과 더불어 절단작업과정에서 발생하는 마찰열을 방출하여 열변형을 방지하여주는 라운딩형상의 강도보강돌기가 연속적으로 돌출형성된 구조로 이루어진 것을 특징으로 한다.The present invention for achieving the above object is a disk-shaped rotary plate formed of a steel material and a plurality of cutting edges bonded to the circumferential surface of the rotary plate by laser welding, the conventional cutting wheel to form the appearance In forming the strength reinforcing device of the cutting wheel, the outer surface of the rotating plate absorbs the vibration generated during the high-speed rotation of the cutting wheel to improve durability and release frictional heat generated during the cutting operation to prevent thermal deformation.

도 2는 본 고안에 따른 절삭휠을 도시한 평면도, 이 도면에 도시된 바와 같이, 강재질로 성형되어진 원판형상의 회전판(10)과, 이 회전판(10)의 둘레면에 레이져용접을 통해 접합된 다수개의 절삭날(20)로, 절삭휠(1)의 외관을 이루게 되는 통상적인 절삭휠용 회전판의 강도보강장치를 구성함에 있어서,2 is a plan view showing a cutting wheel according to the present invention, as shown in this figure, a disk-shaped rotary plate 10 is formed of a steel material, and bonded to the circumferential surface of the rotary plate 10 by laser welding In constructing the strength reinforcing device of a conventional cutting wheel swivel plate forming the appearance of the cutting wheel (1) with a plurality of cutting edges 20,

회전판(10)의 외표면에, 절삭휠(1)의 고속회전과정에서 발생하는 진동을 흡수하여 내구성을 향상시킴과 더불어 절단작업과정에서 발생하는 마찰열을 방출하여 열변형을 방지하여주는 라운딩형상의 강도보강돌기(30)가 연속적으로 돌출형성된 구조로 이루어진 것을 특징으로 한다.The outer surface of the rotating plate 10 absorbs vibrations generated during the high-speed rotation of the cutting wheel 1 to improve durability and to release frictional heat generated during the cutting operation to prevent thermal deformation. Strength reinforcing protrusions (30) is characterized in that consisting of a continuous protrusion formed structure.

먼저, 본 고안에 따른 구성요소 중 회전판(10)의 축공(11)과 흡수공(12)과 접합돌기(13)는 종래 기술과 기능상 상호 동일하므로, 여기서는 자세한 설명은 생략하기로 하고, 다만 회전판(10)의 외표면 형상이 변경된 것에만 그 차이점이 포함되어 있음을 첨언한다.First, the shaft hole 11 and the absorbing hole 12 and the joining projection 13 of the rotating plate 10 of the components according to the present invention are the same as in the prior art and functional, so the detailed description will be omitted here, but the rotating plate It is to be noted that the difference is included only if the outer surface shape of (10) is changed.

그리고, 강도보강돌기(30)는, 회전판(10)의 외표면 즉, 축공(11)과 접합돌기 (13)의 사이공간에 절삭휠(1)의 회전방향과 수직하는 방향으로 연장되는 돌출부재로서, 이러한 강도보강돌기(30)들의 사이공간에 축공(11)로부터 접합돌기(13)를 향해 열방출공간(30a)이 오목하게 형성된다.The strength reinforcing protrusion 30 extends in the direction perpendicular to the direction of rotation of the cutting wheel 1 to the outer surface of the rotating plate 10, that is, the space between the shaft hole 11 and the joining protrusion 13. As such, the heat dissipation space 30a is formed in the space between the strength reinforcing protrusions 30 from the shaft hole 11 toward the joining protrusion 13.

따라서, 강도보강돌기(30)는, 절삭휠(1)이 회전하는 과정에서 회전판(10)의 회전방향과 수직하는 방향으로 강도를 증대시키고, 열방출공간(30a)은, 회전판(10)의 회전과정에서 와류가 발생되게 하여 절삭날(20)로부터 방출되는 열이나 칩과 같은 불순물을 방출시키게 되는 것이다.Therefore, the strength reinforcing protrusion 30 increases the strength in the direction perpendicular to the direction of rotation of the rotating plate 10 while the cutting wheel 1 rotates, and the heat dissipation space 30a of the rotating plate 10 Vortex is generated during the rotation process to release impurities such as heat or chips emitted from the cutting edge 20.

또한, 강도보강돌기(30)의 형상은, 축공(11)로부터 접합돌기(13)를 향해 점차적으로 단면적이 확장되는 형상으로 성형되었는데, 이는 절삭휠(1)의 회전지점을 외측방향을 향하도록하여, 고속회전과정에서 떨림현상을 최소화함은 물론 정밀작업을 가능하게 하기 위한 것이다.In addition, the shape of the strength reinforcing protrusion 30 is formed into a shape in which the cross-sectional area gradually extends from the shaft hole 11 toward the joining protrusion 13, so that the rotation point of the cutting wheel 1 is directed outward. By minimizing the shaking phenomenon in the high-speed rotation process, as well as to enable precise work.

물론, 열방출공간(30a)의 오목형상은, 축공(11)로부터 접합돌기(13)를 향해 점차적으로 단면적이 축소되는 형상으로 성형되었는데, 이는 절삭날(20)에서 발산되는 열이나 방출되는 칩의 방출속도를 최대화하여, 냉각효율 및 불순물제거효율을 극대화하기 위한 것이다.Of course, the concave shape of the heat dissipation space 30a is formed into a shape in which the cross-sectional area is gradually reduced from the axial hole 11 toward the joining protrusion 13, which is the heat dissipated from the cutting edge 20 or the chip being discharged. By maximizing the release rate of, to maximize the cooling efficiency and impurities removal efficiency.

한편, 강도보강돌기(30)의 형성과정을 대략 살펴보면, 절삭휠(1)을 열처리로내에서 열처리하여 강도와 같은 물성을 향상시키는 과정에서 또는 회전판(10)을 원하는 형상으로 성형하는 과정에서 열간프레스와 같은 압축수단을 이용하여 일체로 형성시키는 것이 바람직함은 당연하다.On the other hand, looking at the formation process of the strength reinforcing protrusions 30, in the process of improving the physical properties such as strength by heat-treating the cutting wheel 1 in the heat treatment furnace or in the process of forming the rotating plate 10 to the desired shape Naturally, it is preferable to form integrally using a compression means such as a press.

이상에서 설명한 바와 같인 본 고안에 따른 절삭휠용 회전판의 강도 보강 장치에 의하면, 회전판의 둘레면을 따라 레이져용접을 통해 절삭날이 접합되어진 절삭휠의 외표면에 강도보강돌기를 연속적으로 형성시키므로써, 절삭휠의 고속회전과정에서 발생하는 진동이 흡수되어 내구성이 향상됨은 물론 절삭휠의 작업과정에서 발생하는 열변형이 방지되어 수명이 연장되는 효과가 있는 것이다.According to the strength reinforcing device of the cutting wheel rotary plate according to the present invention as described above, by continuously forming the strength reinforcement protrusions on the outer surface of the cutting wheel bonded to the cutting edge through the laser welding along the circumferential surface of the rotating plate, The vibration generated during the high-speed rotation of the cutting wheel is absorbed to improve durability, as well as to prevent heat deformation generated during the cutting wheel's working process, thereby extending the life.
