Abstract

본 발명은 칼라브라운관의 새도우마스크프레임 및 그 제조방법에 관한 것이다. 종래의 섀도우마스크프레임은 프레임의 중앙대공에 상응하는 상당크기의 스크랩의 발생으로 인하여 상당한 재료손실이 수반되므로 마스크프레임 제작원가의 상승요인이었다 본 발명은 관종에 따른 소망주변길이로 금속판재를 절단하여 하나의 단위부재를 형성하고, 그 단위부재를 가공한 후, 가공된 단위부재의 양단부를 용접하여, 하나의 단위부재로서 프레임을완성 하므로 금속판재의 소비를 최소화함과 동시에 작업공정을 줄이므로써 원가절감에 큰 효과가 있다.The present invention relates to a shadow mask frame of a color brown tube and a method of manufacturing the same. The conventional shadow mask frame is a rising factor of the manufacturing cost of the mask frame due to considerable material loss due to the generation of a large amount of scrap corresponding to the center hole of the frame. After forming one unit member, processing the unit member, and welding the both ends of the processed unit member to complete the frame as one unit member, it minimizes the consumption of metal plate and at the same time reduces the work process. It has a big effect on cost reduction.
