本発明は補強形陰極線管の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for manufacturing a reinforced cathode ray tube.

真空になされている。A cathode ray tube, for example, a color picture tube, has a face plate with a fluorescent screen adhered to its inner surface, a shadow mask disposed at a predetermined distance from the fluorescent screen, and 7
A face plate side wall portion integrally formed on the peripheral edge of the ace plate, a sealing surface of this face plate side wall portion, and a sealing surface of the large diameter portion are connected via frit glass to form a sealing portion and to the small diameter portion. It consists of a funnel to which the neck is welded, and a stem with an assembled electron gun disposed inside the neck, and a high vacuum is created inside the tube via an exhaust pipe provided in the stem.
このため、比較的になだらかな球面をなすフェースプレ
ートの中心から周縁部近傍にかけては圧縮歪、フェース
プレート側壁部、封着面、ファンネルの径大部近傍まで
は張力型が発生し、外力。For this reason, compressive strain occurs from the center of the face plate, which has a relatively smooth spherical surface, to the vicinity of the periphery, and tension type occurs to the side wall of the face plate, the sealing surface, and the vicinity of the large diameter part of the funnel, causing external force.
ガラス部材などの原因により爆縮を起し易い。Implosion is likely to occur due to factors such as glass members.
このため特に大形のカラー受像管などの陰極線管では、
フェースプレート側壁部の外周に防爆処理を行ない補強
形陰極線管にしていることが多い。For this reason, especially in cathode ray tubes such as large color picture tubes,
Explosion-proof treatment is often applied to the outer periphery of the side wall of the face plate to create a reinforced cathode ray tube.
この防爆処理としては大別して次のような種類がある。This explosion-proof treatment can be roughly divided into the following types:
(1)ボンド補強形・・・・・・P、P、G(2)/々

強上有利になっている。(1) Bond reinforced type: P, P, G (2) / Bond reinforced type: Kim cord, T-mend, shrink fit (3) Rim reinforced type:・・P-tube, shell bond 'Among these explosion-proof treatments, in the case of T-band, Kimcord, and shrink fitting, which are tightened using tension bands, apply heat to the front two long tension bands on the side wall of the face plate. A band heating method is used to fix both ends of the winding diameter, and a shrink fitting method is performed in which a tension band is previously formed to have a smaller diameter than the side wall portion of the face plate, and after heating, the side wall portion of the face plate is inserted and cooled. In this case, explosion-proof treatment is performed on the side wall of the face plate, including the mold match line provided on the side wall of the face plate. Strong tightening is advantageous in terms of explosion-proof reinforcement.

ースプレート側に位置ずれを起こすことになる。However, the area from the mold match line to the face plate generally has a three-dimensional complex shape, and the slope is usually large from the mold match line to the sealing surface, so the tension/ζ Tightening of the throat may occur when the force is biased from the mold match line to the face plate side, or when the tension band and the support fittings attached to this tension band (including these below) are tightened. This will cause the reinforcing member (reinforcing member) to shift toward the 7 ace plate.
従って補強部材の位置、締め付は力の配分の選定が補強
形陰極線管の製造工程で重要なポイントになる。Therefore, selecting the position and tightening of the reinforcing member and the distribution of force are important points in the manufacturing process of reinforced cathode ray tubes.

力も限界が、ある問題点がある。Conventionally, this displacement of the reinforcing member has been almost prevented by interposing an explosion-proof tape made of a mesh of glass fibers between the reinforcing member and the side wall of the face plate. However, this explosion-proof tape is expensive and has a limited ability to prevent displacement, which is a problem.

It is an object of the present invention to provide a method for manufacturing a reinforced cathode ray tube that can improve the explosion-proofing effect.

する補強形陰極線管の製造方法である。The present invention provides a reinforced cathode ray tube in which a reinforcing member is tightened by a band method or a shrink-fitting method to include a mold match line provided on the face plate side wall portion of the cathode ray tube. In this manufacturing method, the tightening force of the reinforcing member's side wall of the face plate is equal to or less than the force on the face plate side with the middle mold match line as the border. This method of manufacturing a reinforced cathode ray tube is characterized in that it is carried out under the following conditions.
