Изобретение относитс к электровакуумной промышленности, а именно к оболочкам электроннолучевых приборов , в частности цветных кинескопов.The invention relates to the electrovacuum industry, namely to the shells of electron-beam devices, in particular color picture tubes.

Известны оболочк|1 электроннолучевых приборов, которые включают экран и конус, причем экран имеет ребристую боковую поверхность. Така форма увеличивает прочность прибора 1.Known shell | 1 electron beam devices, which include the screen and the cone, and the screen has a ribbed side surface. This shape increases the strength of the device 1.

Недостатком этого изобретени вл етс то, что при резком перепаде температур целостность оболочки нарушаетс . Такие оболочки имеют достаточно сложную технологию изготовлени .The disadvantage of this invention is that with a sharp temperature difference, the integrity of the shell is broken. Such shells have a rather complicated manufacturing technology.

Известна также колба электроннолучевого прибора, котора содержит экран, сочлененный по периметру со стекл нным конусом при помощи юбки. Экран выполнен в форме, при которой следы сечени его плоскост ми, перпендикул рными оси трубки; близки К пр моугольникам 2.Also known is the bulb of an electron beam device, which contains a screen articulated around the perimeter with a glass cone using a skirt. The screen is made in the form in which the traces of the cross section are its planes perpendicular to the axis of the tube; close to squares 2.

Недостатком этого изобретени вл етс то, что колбы имеют сложные поверхности, дл формовани которых необходимо изготавливать пресс-инструмент весьма сложного профил .The disadvantage of this invention is that the flasks have complex surfaces, for the molding of which it is necessary to manufacture a press tool of a very complex profile.

а в процессе формовани им чрезвычайно трудно управл ть.and in the process of forming it is extremely difficult to control.

До сих пор стеклодетали колбы изготовл лись на стеклоформующих машинах без учета конфигурации деталей , что приводило к усложнению стеклоформующих машин дл обеспечени их размеров. Так, дл изготовлени стеклодеталей, выпускаемых в Until now, glass-making flasks were made on glass-forming machines without taking into account the configuration of parts, which led to the complication of glass-forming machines to ensure their sizes. So, for the manufacture of glass parts produced in

Claims

30 signals by adjusting the angles. This goal is achieved by the fact that in a known flask of an electron-beam device the screen and cone have, in horizontal projection, traces of sections of the outer surface of the cone with planes perpendicular to the central axis of the flask, when crossing with the small, large and diagonal axes, they form curves on the vertical projection, described by the formula () S а (xd) 4-О In addition, a part of the traces of sections from the cone end to its rectilinear section at the intersection with the diagonal axis form a curve described by the formula yd + V (Rd) - {x-xo) 2d (2) where y is the distance m forward adjacent planes, perpendicular to the central axis of the flask; d is the screen diagonal of the electron-beam device; - coefficient of equation (1); X is the distance on the horizontal projection from the central axis of the bulb to the outer surface of the cone; R is the length of the radius of the curve from the end of the cone to its straight portion of the external surface of the cone; Od - the vertical coordinate of the center of the radius; X is the horizontal coordinate of the center of the radius. FIG. Figure 1 shows a flask with vertical sections along small, large, and diagonal axes; in fig. 2 - count ba Electronic Instrument device in the plan. FIG. Figure 1 shows horizontal sections of the planes from O to n, which are perpendicular to the central axis of the bulb — the Y axis. The cone 1. x from each other .. The boundaries of the traces of sections of the planes, intersecting with the small, large and diagonal axes, form the curves of the external contour of the cone of the bulb. The curves along the small x, large x, and diagonal axes are divided into characteristic sections (see table). The curve section along the diagonal axis is determined by formula (2), and the remaining sections - by formula (1). Formulas (1) and (2) are reduced to a dimensionless form in order to determine the characteristic curve for a flask with a cone having a beam sweep angle depending on the size of the screen diagonal. The value of the coefficients for formula (1), depending on the sections of the curve on each axis, are given in the table. The proposed form of the shell is achieved on conventional low-speed glass-forming machines with pneumatic actuator with an effective industrial production of parts with low operating costs and a small amount of glass melt. Deviation of parts from the proposed form dramatically reduces production efficiency with a significant complication of machines and an increase in the specific consumption of glass melt. The use of the present invention for making flasks of electron beam devices of color kinescopes makes it possible to increase the information from the screen by 10% and to improve the image quality.
