Abstract

본 발명은 음극선광용 전자총 전극의 음극지지체 제조방법에 관한 것으로써, 좀더 구체적으로는 비드써포터와 음극 아일렛과의 용접고정이 양호하게 되도록 하여 전자총의 품질과 생산성을 향상시키는데 유리하도록 한 것이다.The present invention relates to a method for manufacturing a cathode support of an electron gun electrode for cathode ray light, and more particularly, to improve welding quality between a bead supporter and a cathode eyelet, thereby improving the quality and productivity of the electron gun.

이를 위해, 판상의 소재(A)에 복수개의 돌기(13a) 중심을 평행하게 형성하는 제1단계와, 상기 1단계를 거친 소재를 음극 아일렛(13)의 외주면 곡률과 일치되는 곡률부(14b)가 형성되게 절곡하게 비드써포트(14)를 얻는 제2단계와, 제2단계를 거쳐 얻어진 비드써포터(14)를 음극 아일렛(13)의 외주면에 접속시킨 다음 용접 고정하는 제3단계를 차례로 수행하도록 된 것이다.To this end, the first step of forming the center of the plurality of protrusions 13a in parallel with the plate-like material A, and the curvature portion 14b in which the material that passed through the first step matches the curvature of the outer circumferential surface of the cathode eyelet 13 To perform the second step of obtaining the bead support 14 bent so that the bead is formed, and the third step of connecting the bead supporter 14 obtained through the second step to the outer circumferential surface of the negative electrode eyelet 13 and then welding and fixing it. It is.
