Description
본 발명은 유리 절단용 스크라이빙 휠에 관한 것으로써, 더욱 상세하게는 외주연 양측면에 경사지게 형성된 날부위에 방사상의 돌기와 홈을 형성하여 날 끝에 톱니를 구성함으로써 유리 절단시 슬립(미끄럼)을 방지하고, 깨끗한 절단가공면을 얻을 수 있도록 한 스크라이빙 휠에 관한 것이다.The present invention relates to a scribing wheel for cutting glass, and more particularly, radial protrusions and grooves are formed on blades formed to be inclined on both sides of the outer circumference to form teeth at the blade to prevent slippage during glass cutting. The present invention relates to a scribing wheel capable of obtaining a clean cutting surface.
종래의 유리 절단용 스크라이빙 휠(100)은 도 4에 도시된 바와 같이 스크라이빙머신에 체결하기 위한 축결합 구멍(200)이 중심부에 형성되고, 외주연의 날 끝(300) 양측면에 경사지게 형성된 날부위(400)에 돌기(500)와 홈(600)이 원주방향으로 구성된 것이다.The conventional glass cutting scribing wheel 100 has a shaft coupling hole 200 for fastening to the scribing machine is formed in the center, as shown in Figure 4, on both sides of the blade edge 300 of the outer circumference The protrusion 500 and the groove 600 are configured in the circumferential direction on the blade portion 400 formed to be inclined.
그러나, 상기 스크라이빙 휠(100)의 경우 날부위(400)를 형성하는 돌기(500)와 홈(600)이 원주방향으로 구성되어 있기 때문에 유리 절단시 미끄럼이 발생되어 정확한 절단작업을 수행하기 힘들고, 절단된 유리의 절단가공면 또한 깨끗하지 못하여 생산성과 품질이 떨어지는 문제가 있다. However, in the case of the scribing wheel 100, since the protrusions 500 and the grooves 600 forming the blade portion 400 are configured in the circumferential direction, sliding occurs during the cutting of the glass to perform accurate cutting operations. Difficult, the cut surface of the cut glass is also not clean, there is a problem that the productivity and quality falls.
본 발명은 상술한 제반 문제점을 해결하기 위하여 발명된 것으로써 LCD용 유리 등을 절단할 때 스크라이빙 휠과 유리 사이에 슬립이 방지되도록 날부위에 방사상의 돌기와 홈을 형성하여 날 끝에 톱니를 구성함으로써 정확한 절단작업을 수행하고, 깨끗한 유리 절단가공면을 얻어 품질을 향상시키는데 그 목적이 있다.The present invention has been invented to solve the above-mentioned problems as forming a radial projection and groove on the blade to form a sawtooth at the blade so as to prevent slip between the scribing wheel and the glass when cutting the glass for LCD, etc. The purpose is to perform accurate cutting work and to obtain a clean glass cutting surface to improve quality.
본 발명의 유리 절단용 스크라이빙 휠(Scribing Wheel)의 구성을 이하, 첨부된 도면과 관련하여 상세하게 설명하면 다음과 같다.Hereinafter, the configuration of a scribing wheel for cutting glass of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 유리 절단용 스크라이빙 휠은 초경합금으로 제작된다.In the present invention, the scribing wheel for cutting glass is made of cemented carbide.
또한 본 발명은 초경합금제 스크라이빙 휠은 외주연 양측면에 형성되는 날부위에 돌기와 홈을 방사상으로 형성함과 동시에 날 끝에 톱니가 구성되도록 하여 유리 절단시의 슬립(미끄럼)을 방지하므로 정확한 절단작업이 이루어지고, 깨끗한 절단가공면을 얻을 수 있도록 한 것을 특징으로 한다.In the present invention, the cemented carbide scribing wheel is provided with radial projections and grooves on the blades formed on both sides of the outer periphery, and at the same time the teeth are formed at the blades to prevent slips (slips) during glass cutting. This is done, characterized in that to obtain a clean cutting surface.
본 발명은 초경합금제 스크라이빙 휠(1)은 스크라이빙머신에 체결하기 위한 축결합 구멍(2)이 중심부에 형성하고, 외주연 양측면에 경사지게 형성되는 날부위(5)에는 방사상의 돌기(7)와 홈(8)을 구성한 것이다.According to the present invention, the cemented carbide scribing wheel 1 has a axial coupling hole 2 for fastening to a scribing machine in a central portion thereof, and a radial protrusion having a radial protrusion 5 formed at an inclined surface on both sides of the outer circumference thereof. 7) and the groove (8) is configured.
상기 스크라이빙 휠(1)의 외주연 날 끝(6)에는 날부위(5)에 형성되는 돌기(7)와 홈(8)에 의하여 톱니(3)를 갖도록 구성되어 있다.The outer peripheral edge 6 of the scribing wheel 1 is configured to have a tooth 3 by means of a projection 7 and a groove 8 formed in the blade portion 5.
상기 돌기(7)와 홈(8)의 깊이는 20미크론이므로 육안으로는 보이지 않는다.Since the depths of the protrusions 7 and the grooves 8 are 20 microns, they are not visible to the naked eye.
상기 스크라이빙 휠(1)은 날 끝(6) 양측으로 경사지게 형성된 날부위(5)의 돌기(7)와 홈(8)이 방사상, 즉 원주방향과 수직방향으로 결이 형성되면서 톱니(4)가 구성되어 있기 때문에 유리 절단시 회전하는 스크라이빙 휠(1)와 유리사이에서 발생되는 슬립(미끄럼)이 방지되어 정확한 절단작업을 수행할 수 있고, 절단된 유리의 절단가공면 또한 깨끗하다.The scribing wheel 1 has a tooth 4 as the projection 7 and the groove 8 of the blade portion 5 formed to be inclined to both sides of the blade tip 6 are formed radially, that is, in a circumferential direction and a vertical direction. ), It is possible to prevent the slip (slip) generated between the scribing wheel (1) that rotates during the glass cutting and the glass to perform accurate cutting work, and the cutting surface of the cut glass is also clean .
또한 본 발명의 스크라이빙 휠(1)은 축결합 구멍(2)과 날부위(5) 사이를 래핑가공하여 0.1~0.8-S의 조도를 갖는 래핑부(4)를 구성함으로써 절단저항을 줄였다. In addition, the scribing wheel 1 of the present invention reduces the cutting resistance by lapping the shaft coupling hole 2 and the blade portion 5 to form a wrapping portion 4 having a roughness of 0.1 to 0.8-S. .
상술한 본 발명의 초경합금제 스크라이빙 휠는 날 끝의 양측에 경사지게 형성되는 날부위에 구비되는 돌기와 홈을 방사상, 즉 원주방향과 수직방향으로 결을 형성하여 톱니를 갖도록 함으로써 유리 절단시의 슬립(미끄럼)을 방지하여 정확한 절단작업을 수행하고, 깨끗한 절단가공면을 얻을 수 있는 등 생산성과 품질을 향상시키는 효과가 있다. The above-described cemented carbide scribing wheel of the present invention is formed by forming projections and grooves provided on the blades that are inclined at both sides of the blade tip in a radial direction, that is, in the circumferential direction and the vertical direction so as to have teeth, thereby slipping the glass during the cutting ( It is effective in improving productivity and quality by preventing slippage, performing accurate cutting operations, and obtaining clean cutting surfaces.
또한 본 발명은 스크라이빙 휠에 래핑부를 형성하여 절단저항을 줄임으로써 절단력을 높이고 공구의 수명을 연장시키는 등의 효과가 있다.In addition, the present invention has the effect of increasing the cutting force and extending the life of the tool by reducing the cutting resistance by forming a wrapping portion on the scribing wheel.
