It is an A sectional view. In the figure, 1 is a reinforcing ring, 2 is a valve, and 3 is a tape. As shown, 300~500℃
A reinforcing ring heated and expanded is fitted near the valve mold match of the cathode ray tube, and as the reinforcing ring cools and contracts, it tightens the outer periphery of the side surface of the bulb near the mold match to produce a reinforcing effect.
However, the inner dimensions of the reinforcing ring and the outer circumferential dimensions of the valve,
Each has a tolerance, and it is unavoidable that some variation will occur in the mutual positions of the reinforcing ring and the bulb after shrink fitting. These tolerances, variations, etc. are generally not constant in proportion to the target dimensions, but often take constant values determined by each work and the machine used. Therefore, in the case of small tubes, the tolerances and variations are proportionally greater than in the case of large tubes. On the other hand, thermal expansion, etc., is proportionally the same for both large and small pipes at the same temperature. Therefore, when it comes to small pipes,
As the effects of tolerances and variations have become greater, reinforced cathode ray tubes using the conventional reinforced ring shrink fitting method have had the problem of not being able to provide sufficient reinforcement to prevent implosion with stability and good yields. Ta.

を提供することを目的とする。 The present invention provides a reinforced cathode ray tube which eliminates the problems of the reinforced cathode ray tube caused by the conventional reinforced ring shrink fitting method, and which can be easily manufactured in terms of both parts and work in almost the same way as the conventional shrink fitting method. The purpose is to provide a manufacturing method.

A plurality of tensioning handles are provided in advance on the reinforcing ring, and the reinforcing ring is heated and pulled with a tension within the elastic limit through the handles, so that the inner dimension of the reinforcing ring is made smaller than its value at normal temperature and without tension. In a sufficiently large state, we decided to fit the reinforcing ring to the outer periphery of the side surface near the valve mold match of the cathode ray tube.

などを用いて簡単に実施できる。 FIG. 3 is a front view of one embodiment of the present invention, FIG. 4 is a sectional view taken along line BB in FIG. 3, and FIG. 5 is a perspective view of the vicinity of the reinforcing ring tensioning handle of the same embodiment. In the figure, 1' is a reinforcing ring provided with a tension handle 4, and the other symbols are the same as in FIGS. 1 and 2. While heating the reinforcing ring 1' to 300 to 500°C, pull the handles 4 at the four corners of the reinforcing ring almost diagonally,
A tension of ~100 Kg/mm 3 is applied almost equally to each side of the reinforcing ring 1'. In this way, the reinforcing effect is always stable and good, almost unaffected by the tolerances of the inner dimensions of the reinforcing ring, the outer circumferential dimensions of the valve, and variations in the position where the reinforcing ring 1' is fitted to the outside of the valve 2. is obtained. If the face panel is rectangular, as in this embodiment, by pulling the handles 4 provided at four locations of the reinforcing ring 1' corresponding to the four corners of the face panel in an approximately diagonal direction, the reinforcing ring 1' can be removed. It is possible to apply tension of approximately equal strength to each part, and the inner shape of the reinforcing ring 1' becomes an enlarged shape similar to the original shape, making it easy to implement the present invention. If the face panel is circular, etc., when the handle 4 is pulled, the reinforcing ring may deform into a polygonal shape and become unable to fit into the valve, so consider the number of handles and measures to prevent deformation of the base of the handle. Must. FIG. 6 is a perspective view showing another shape of the handle 4. Note that pulling the handle 4 can be easily carried out using a hydraulic device or the like.

By simply adding it, you can obtain a cathode ray tube that is always stable and well reinforced against implosion.
