그런데, 상기 슬리이브의 가장자리에 형성된 버를 제거하는 제4공정의 수행은 각 슬리이브에 부착된 버를 작업자가 수작업으로써 제거하거나 소정의 용액에 담가 녹여내는 방법을 사용하여 왔다. 그러나 상기와 같이 작업자가 슬리이브에 부착된 버를 제거하는 경우에는 버의 제거에 따른 많은 작업공수가 소요되는 문제점이 있으며, 용액에 담가 녹여내는 방법은 슬리이브(12)의 외표면을 손상시키게 되는 문제점이 있었다.By the way, the fourth step of removing burrs formed at the edges of the sleeves has been performed by a method of manually removing burrs attached to each sleeve or immersing them in a predetermined solution. However, when the worker removes the burr attached to the sleeve as described above, there is a problem that a lot of work is required according to the removal of the burr, the method of soaking in the solution to damage the outer surface of the sleeve (12). There was a problem.

본 발명은 상기 문제점을 해결하기 위하여 안출된 것으로, 슬리이브의 가장자리에 부착된 버의 제거에 따른 불량의 발생과 작업공수를 대폭 줄일 수 있는 캐소오드의 슬리이브 제작 방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, it is an object of the present invention to provide a sleeve manufacturing method of the cathode that can significantly reduce the occurrence of defects and labor due to the removal of the burr attached to the edge of the sleeve. .

상기 목적을 달성하기 위하여 본 발명은, 관상의 소재를 인발가공하여 소정 직경의 튜브로 제작하는 제1공정과 상기 튜브를 소정길이로 절단하여 슬리이브를 제작하는 제2공정과 절단시 발생된 버를 제거하는 제3공정을 포함하여 된 슬리이브 제조공정을 포함하여 된 캐소오드 구조체의 제조방법에 있어서, 상기 슬리이브로 부터 버를 제거하는 상기 제3공정이 분말상의 연마석과 절단된 슬리이브를 혼합하는 단계와, 혼합된 연마석과 슬리이브가 혼합된 상태에서 흔드는 단계를 포함하여 된 것을 그 특징으로 한다.In order to achieve the above object, the present invention, the first process of drawing a tubular material by drawing a tube of a predetermined diameter and the second process of producing a sleeve by cutting the tube to a predetermined length and a burr generated during cutting In the method of manufacturing a cathode structure comprising a sleeve manufacturing step including a third step of removing the step, wherein the third step of removing the burr from the sleeve is a powdered abrasive stone and cut sleeve And mixing and shaking the mixed abrasive stone and the sleeve in a mixed state.

이하 첨부된 도면을 참조하여 본 발명에 따른 한 바람직한 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

전자총의 캐소오드 구조체는 도 1에 나타내 보인바와 같이 전자방사물질이 충진된 음극기체(20)가 설치된 저장조(11)와 이 저장조(11)를 지지하며 그 내부에 히이터(13)가 설치된 슬리이브(12)을 구비하여 구성된다.As shown in FIG. 1, the cathode structure of the electron gun is a storage tank 11 in which a cathode gas 20 filled with an electron-spinning material is installed, and a sleeve 13 supporting the storage tank 11 and having a heater 13 installed therein. It is comprised with 12.

상기와 같이 구성된 캐소오드 구조체의 제조방법은 상술한 각 부재를 각각의 공정순서에 따라 제작한 후 이들을 결합하여 제작하게 되는데, 상기 캐소오드 구조체의 제조 방법중 슬리이브의 제조방법은 관상의 소재를 인발가공하여 소정의 직경의 튜브로 제작하는 제1공정과, 튜브를 소정의 길이로 절단하는 제2공정과, 튜브의 절단시 발생된 슬리이브의 가장자리에 형성된 버를 제거하는 제3공정을 포함하여 이루어진다. 상기 제3공정은 본 발명의 특징에 따라 소정의 길이로 절단된 슬리이브와 연마석 가루를 섞는 단계와, 혼합된 연마석과 슬리이브로 뒤섞이도록 흔들어 슬리이브(12)의 절단된 부위에 형성된 버가 연마되도록 하는 단계를 포함하여 된 것이다. 상기 제3공정중 혼합된 연마석과 슬리이브를 흔드는 단계는 회전하는 드럼의 내부에 연마석과 슬리이브를 넣고 드럼을 회전시키는 것이 바람직하다.The method of manufacturing a cathode structure configured as described above is to produce each of the above-described members in accordance with the respective process sequence and then to combine them, the manufacturing method of the sleeve of the method of manufacturing the cathode structure is a tubular material A first step of drawing the tube into a tube having a predetermined diameter; a second step of cutting the tube into a predetermined length; and a third step of removing burrs formed at the edge of the sleeve generated when the tube is cut. It is done by In the third step, the burrs formed on the cut portion of the sleeve 12 by mixing the sleeve and the abrasive stone powder cut to a predetermined length according to the characteristics of the present invention and shaking the mixture with the mixed abrasive stone and the sleeve It is to include the step of being polished. In the shaking of the mixed abrasive stone and the sleeve during the third process, it is preferable to put the abrasive stone and the sleeve into the rotating drum and rotate the drum.

이상에서 설명한 바와같이 본 고안 캐소오드 구조체의 제조방법은 슬리이브에 형성된 버가 혼합된 연마석에 의해 부딪기면서 연마되게 되므로 슬리이브의 외표면에 큰 손상을 주지 않고 버를 제거할 수 있으며, 종래와 같이 버의 제거에 따른 작업공수를 대폭 줄일 수 있어 생산성의 향상을 도모할 수 있는 이점이 있다.As described above, in the method of manufacturing the cathode structure according to the present invention, the burr formed in the sleeve is polished while being hit by the mixed abrasive stone, so that the burr can be removed without causing great damage to the outer surface of the sleeve. Likewise, since the number of labors due to the removal of burrs can be greatly reduced, productivity can be improved.
