A sealing bracket graphite stopper, including the center column and a bracket, the upper end of the bracket is fixed with a screen stopper and a cone stopper, and the lower end of the bracket is arranged horizontally curved supporting seat is connected with the arc-shaped supporting seat is provided with a conical support block, cone support block cavity is provided with a T type. Cone hole, pin with the fixed seat through the supporting block and the T type cone hole supporting block fixing pin and the arc supporting block is connected. The utility model cone supporting block is changed from the former half metal coated graphite type fixing graphite metal package type fixing cone, the supporting block is fixed pin from cone supporting block center insert, then the pin pin fastened on the fixed seat, so as to complete the full metal graphite type fixed way, in the color picture tube. The Department of partial cone bumps a fundamental change, eliminates the hidden danger of the color kinescope, and fully guarantee the consistency of the geometric center of screen cone completely coincident.
【技术实现步骤摘要】
本技术涉及一种用于彩色显像管制造中的高温封接炉炉内低熔点玻璃熔封屏和锥的设备，特别涉及一种封接支架石墨止动器。
技术介绍
在彩色显像管制造过程中，屏锥均属玻璃制品，在440℃高温下既要保证屏锥几何中心完全重合，也要保证玻璃制品与封接专用的封接支架间在高温下不能应相互之间的接触而产生玻璃制品熔封的玻壳产生应力变化，从而使玻壳产生破裂现象。在正常生产中，作业人员选好封接支架后，从传送带上取下锥体，将锥体放到封接支架上，保证支架上的锥止动器、管颈止动器、锥支撑块与锥体紧密接触；再从屏除尘设备上取出屏，将屏轻轻地放到锥体上，使屏与支架上的屏止动器紧密接触，与锥配合完好，并确认无封接偏移。封接支架自动传送进入高温封接炉中进行高温封接，使屏锥熔封在一起，形成彩管玻壳。日常生产中，封接支架上与屏锥相接触的备件是柱状屏止动器、柱状锥止动器、柱状锥支承块、块状管颈止动器，均为石墨材质。三个屏止动器与玻壳的屏三点接触，三个锥止动器与锥上方三点接触，一个锥支撑块与锥体偏转部一点接触，一个管颈止动器与锥体管颈面接触。石墨在封接炉内高温、高速风力及反复与屏锥的接触磨擦下，石墨表面经常被磨...
【技术保护点】
一种封接支架石墨止动器，包括中心立柱［８］和设置在中心立柱［８］上的支架［３］，支架［３］的上端固定有屏止动器［１］和锥止动器［２］，支架［３］的下端与水平设置的弧形支撑座［９］相连接，弧形支撑座［９］上设置有锥支撑块［４］，其特征在于：所说的锥支撑块［４］的内腔开设有一Ｔ型通孔［１０］，锥支撑块［４］通过带有通孔［１２］的销子固定座［７］和Ｔ型锥支撑块固定销子［６］与弧形支撑块［９］相连接。
