Abstract

본 발명은 평면마스크를 곡면마스크로 성형하는 즉시 동일 포지션상에서 프레임과 접합하는 음극선관의 마스크성형과 동시 프레임조립방법, 그 프레임 및 그 장치에 관한 것이다.BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method for mask forming and simultaneous frame assembly of a cathode ray tube joined to a frame on the same position as soon as the planar mask is formed into a curved mask, the frame and the apparatus thereof.

평면마스크를 곡면마스크로 성형하는 펀치(punch), 다이(die), 녹아웃(knock out)을 구비하는 마스크 성형장치에 의하여,평면마스크를 곡면마스크로 성형하는 즉시 동일 포지션상에서 프레임과 접합함에 있어서, 프레임의 로딩 및 취출이 다이의 상단에서 이루어지며, 로딩된 프레임은 고정된채 마스크가 프레임의 내벽에 안내되어 하강하여 프레임에 조립되며 이러한 상태에서 용접을 이루게 하므로서 종래에서와 같이 프레스 금형에서 새도우마스크만을 포밍하고 포밍된 새도우마스크를 세척 및 흑화공정을 거치며 별도의 용접다이에서 마스크-프레임용접조립을 하게되는 번거로움이 없이 프레스머신에서 새도우마스크포밍과 동시에 프레임조립을 완료되어 다음공정인 세척 및 흑화공정을 취하게 됨에 따라 별도의 용접다이에서 마스크-프레임용접조립을 하게되는 공정을 단축시키게되는 효과가 있게된다.In a mask forming apparatus having a punch, a die, and a knockout for forming a flat mask into a curved mask, in forming the flat mask into a curved mask and immediately joining the frame on the same position, The loading and withdrawal of the frame takes place at the top of the die. The loaded frame is fixed and the mask is guided to the inner wall of the frame and lowered, assembled to the frame, and welded in this state, thus making the shadow mask in the press mold as usual. Forming the bay, washing and blackening the formed shadow masks and mask-frame welding assembly on a separate welding die without shadow mask forming on the press machine and frame assembly are completed at the same time. Mask-frame welding assembly on a separate welding die as the process is taken It is possible that the effect to shorten the processes.
