Description

피복관 및 전열관 면취용 디버링툴{DEBURRING TOOL FOR REMOVING BURRS ON THE CLADDING TUBE AND STEAM GENERATOR TUBE}[0001] DEBURRING TOOL FOR REMOVING BURRS ON THE CLADDING TUBE AND STEAM GENERATOR TUBE [0002]

본 발명은 원자력연료 피복관 및 전열관의 외면, 내면, 전면을 면취하는 디버링툴(Deburring Tool)에 관한 것으로, 더욱 상세하게는 원자력발전소 등에서 사용되는 튜브 등의 제조공정중 발생하는 버어(Burr)를 제거하기 위한 디버링툴(Deburring Tool)의 발명에 대한 것이다. The present invention relates to a deburring tool for cutting the outer surface, inner surface, and front surface of a nuclear fuel cladding tube and a heat transfer tube, and more particularly to a deburring tool for removing burrs generated during a manufacturing process of a tube used in a nuclear power plant, The invention relates to a deburring tool.

본 발명은 몸체와 절삭팁(Tip)을 서로 분리, 결합이 가능하도록 개선하여 툴 제작비용을 절감시키고 팁(Tip)의 마모 및 파손시 교체비용 및 시간을 저감하여 업무효율을 향상시키기 위한 튜브의 외면, 내면, 전면을 절삭하는 디버링툴(Deburring Tool)에 관한 것이다.
The present invention relates to a method of manufacturing a tube for improving work efficiency by reducing the manufacturing cost of the tool by improving the separation of the body and the cutting tip from each other so that the tip and the tip can be separated from each other, And to a deburring tool for cutting an outer surface, an inner surface, and a front surface.

경수로의 원자로에서 연료 어셈블리에는 중성자 흡수 특성이 낮은 지르코늄 합금을 포함하는 소재를 사용하게 되며, 예를 들어 지르코늄 합금의 피복관 또는 인코넬 전열관과 같은 튜브형 제품은 일반적으로 성형 및 기계적 가공에 의해 잉곳으로부터 얻은 봉의 압출에 의해 제조된다.For fuel assemblies in light-water reactors, tubular products, such as zirconium alloy cladding or inconel heat pipes, typically use a material containing a low-neutron-absorbing zirconium alloy, And is produced by extrusion.

한편, 튜브형 제품을 소정 사이즈의 튜브로 제작하기 위하여 필거장치에 의해 연성 튜브의 직경을 축방향으로 연신시키고 감소시키게 되며, 이러한 필거공정에서 자동공급장치에 의해 튜브가 이송되는 과정에서 튜브 끝 갈라짐(split)이 발생할 경우에는 장비가 비상으로 정지하는 상황이 발생하기 때문에 튜브 끝의 버어(Burr)는 철저한 관리가 요구된다.Meanwhile, in order to fabricate a tubular product into a tube having a predetermined size, the diameter of the flexible tube is extended and reduced in the axial direction by a wringer, and during the feeding of the tube by the automatic feeder, If the split occurs, the equipment will be shut down in an emergency, so the burrs at the end of the tube must be thoroughly controlled.

일반적으로 이런 종류의 튜브 제조공정 과정에서 발생되는 버어(Burr)를 제거하기 위하여 디버링툴이 사용된다.In general, a deburring tool is used to remove burrs generated during the manufacturing process of this kind of tube.

종래의 튜브의 외면, 내면, 전면을 절삭하는 디버링툴은 도 1에 도시된 바와 같이, 회전축이 몸체부(10)의 중앙에 형성된 장착홈(11)에 결합된다.1, a rotating shaft is coupled to a mounting groove 11 formed at the center of the body portion 10, as shown in FIG. 1, in a conventional deburring tool for cutting an outer surface, an inner surface, and a front surface of the tube.

몸체부(10)의 상부에는 경사진 외면절삭부(20)가 돌출형성된다.An inclined outer cutter 20 is protruded from the upper portion of the body 10.

외면절삭부(20)는 튜브가 밀착된 상태에서 외면절삭부(20)의 경사진 면으로 외면에 발생된 버어(Burr)를 제거한다.The outer cutter 20 removes burrs generated on the outer surface of the outer cutter 20 with the slanted surface of the outer cutter 20 while the tube is in close contact.

또한, 몸체부(10)에는 외면절삭부(20)와 같이 상부가 경사진 내면절삭부(30)가 일단부 중앙에 돌출형성된다.In addition, the body 10 has an inner cutter 30 protruding from the center of the one end, such as the outer cutter 20, whose upper portion is inclined.

내면절삭부(30)는 밀착된 튜브의 내면에 삽입되어 내면에 발생된 버어(Burr)를 제거한다.The inner surface cutting portion 30 is inserted into the inner surface of the tightly coupled tube to remove burrs generated on the inner surface.

또한, 몸체부(10)에는 외면절삭부(20)와 내면절삭부(30)의 사이에 약간의 깊이를 갖는 전면절삭부(40)가 형성된다.The body portion 10 is formed with a front cutting portion 40 having a slight depth between the outer cutting portion 20 and the inner cutting portion 30. [

전면절삭부(40)는 외면절삭부(20), 내면절삭부(30)와 함께 디버링툴에 밀착된 튜브의 전면에 발생한 버어(Burr)를 제거한다.The front cutting portion 40 removes a burr formed on the front surface of the tube which is in close contact with the deburring tool together with the outer surface cutting portion 20 and the inner surface cutting portion 30.

그러나, 이러한 종래의 디버링툴(Deburring Tool)은 필거링 후에 냉간압연으로 인한 가공 경화된 튜브의 양쪽 끝단을 디버링하기 때문에 디버링툴의 마모가 심하며, 특히 절삭팁이 몸체와 일체형으로 구성됨에 따라서 디버링(Deburring)작업시 외면, 내면, 전면 절삭면 중 어느 한 쪽면이라도 마모되거나 파손되면 디버링툴(Deburring Tool) 전체를 교체해야 하는 문제점이 있다.However, since such a conventional deburring tool deburls both ends of the work hardened tube due to cold rolling after the fill ging, wear of the deburring tool is significant, and in particular, since the cutting tip is integrally formed with the body, Deburring) is worn or damaged even if the outer surface, the inner surface, or the front cutting surface is worn, it is necessary to replace the entire deburring tool.

또한, 디버링툴(Deburring Tool) 전체를 교체할 때 소요되는 비용 및 시간 발생으로 업무효율이 저하되는 문제점도 있다.
In addition, there is a problem that work efficiency is lowered due to cost and time required when replacing the entire deburring tool.

상부의 경사진 제1절삭부(200)에는 제1절삭팁(210)이 장착될 수 있도록 제1절삭팁(210)과 동일한 크기와 형상을 갖는 결합홈(500)이 형성된다.The first inclined upper portion 200 has a coupling groove 500 having the same size and shape as the first cutting tip 210 so that the first cutting tip 210 can be mounted.

아래에서 설명하는 3개면의 절삭부(200, 300, 400)에는 결합되는 절삭팁(210, 310, 410)이 용이하게 분리되기 위하여 결합홈(500) 및 분리홈(510)이 형성된다.The coupling grooves 500 and the separation grooves 510 are formed in the three cut surfaces 200, 300 and 400 described below so that the cutting tips 210, 310 and 410 to be coupled are easily separated.

분리홈(510)은 직경이 작은 원형 형상이고, 결합홈(500)은 삼각형 형상이며 모서리 부분이 개방되도록 형성된다.The separation groove 510 has a circular shape with a small diameter, and the coupling groove 500 has a triangular shape and an edge portion is formed to be opened.

분리홈(510)은 결합된 절삭팁(210, 310, 410)의 모서리가 양쪽으로 개방되어 있어 이를 통해 절삭부(200, 300, 400)와 절삭팁(210, 310, 410)의 분리가 용이하다.The separation grooves 510 facilitate the separation of the cutting portions 200, 300, 400 and the cutting tips 210, 310, 410 through the edges of the coupled cutting tips 210, 310, Do.

제1절삭팁(210)은 다각형 형상이며, 한쪽 면을 이용하여 버어(Burr)를 제거한다.The first cutting tip 210 has a polygonal shape, and one side is used to remove the burr.

제1절삭팁(210)의 재질은 고속도 공구강 또는 초경 합금 등이며, 별도의 볼트를 이용하여 제1절삭부(200)에 결합된다.The material of the first cutting tip 210 is a high-speed tool steel, a cemented carbide, or the like, and is coupled to the first cutting portion 200 using a separate bolt.

제1절삭부(200)에 결합된 제1절삭팁(210)은 몸체부(100)에 밀착된 튜브(T)의 외면에 발생된 버어(Burr)를 말끔하게 제거한다.The first cutting tip 210 coupled to the first cutting portion 200 smoothly removes burrs generated on the outer surface of the tube T adhered to the body portion 100.

절삭되는 과정에서 제1절삭팁(210)은 마모되거나 파손되어 교체가 불가피할 경우에 고정된 별도의 볼트를 회전시켜 제1절삭부(200)로부터 고정상태가 해제된다.In the course of cutting, when the first cutting tip 210 is worn or damaged and replacement is inevitable, the fixed bolt is rotated to release the fixed state from the first cutting portion 200.

해제된 제1절삭팁(210)은 제1절삭부(200)에 형성된 분리홈(510)을 통해 제1절삭부(200)로부터 완전히 분리된다.The released first cutting tip 210 is completely separated from the first cutting portion 200 through the separation groove 510 formed in the first cutting portion 200.

교체되는 제1절삭팁(210)은 제1절삭부(200)에 형성된 결합홈(500)에 삽입된 후, 별도의 볼트를 이용하여 결합된다.The first cutting tip 210 to be replaced is inserted into the coupling groove 500 formed in the first cutting portion 200 and then coupled using a separate bolt.

제2절삭부(300)는 몸체부(100)의 일단부에 내면로 단차지게 돌출형성되고, 돌출된 상부에 분리, 결합이 가능한 제2절삭팁(310)이 경사지게 장착된다.The second cutting part 300 is formed at one end of the body 100 so as to be stepped on the inner surface, and a second cutting tip 310 capable of being detached and coupled to the protruded upper part is slantly mounted.
