の作業となり能率が低下する。Conventional configuration and its problems In general, when connecting a glass bulb and an exhaust pipe, the end faces of the glass bulb and the exhaust pipe to be connected are heated in a separated state, and when the end faces reach a molten state, The two are brought together and connected. In the above connection method, the inner diameter of the end face to be connected is reduced due to shrinkage due to shrinkage and thickening.
Because the exhaust pipe and the glass bulb abut each other, a build-up occurs at the connection part and the inner diameter becomes smaller. Therefore,
It is difficult to remove strain from a connection where a buildup has occurred, and cracks may occur due to reheating near the connection, and the residual strain may increase, resulting in a glass bulb with a high risk of breakage. The inner diameter reduces exhaust efficiency. In order to prevent these, the flesh pockets are removed by reheating and applying pressure from the inner surface of the glass bulb with compressed air to correct the flesh pockets and small inner diameter. As the time increases, the inside of the glass bulb often becomes contaminated. In addition, when connecting a glass bulb and an exhaust pipe, if the end faces of the glass bulb and exhaust pipe to be connected are separated and the end faces are heated with a heating flame, the edge portion of the end will spread heat due to conduction. is small and causes a heat accumulation phenomenon, so that the temperature rises more rapidly than the portions other than the edge portions of the end face. When aluminoborosilicate glass containing SiO 2 and Al 2 O 3 as main components is used, this rapid temperature rise at the edge of the end face induces a reboiling phenomenon peculiar to the glass, causing a loss of airtightness. This results in defects such as decreased mechanical strength and reduced commercial value due to clouding of processed parts. In order to avoid such a rapid temperature rise at the edge of the end face and to prevent the occurrence of re-boiling, a heating flame at a lower temperature must be used, resulting in a long work time and reduced efficiency.

る。 In FIG. 2, the glass bulb 2 and the exhaust pipe 1 held in the holder are placed at the reference line X at a.
-X' is provided with a regulating plate (not shown) having a thickness of t, and the glass bulb 2 and the exhaust pipe 1 are regulated at a distance t. At this time, the end surface to which the glass bulb 2 is connected is located on the reference line X-X', and the end surface to which the exhaust pipe 1 is connected is located at a distance t from the reference line X-X'.
It is located in The rail at a is set on the x-x' plane of the main body 3 at a height k. While the drive table is rotating from a to b, the rail is set lower by the height t, so the exhaust pipe 1 descends to the reference line X-X', and the glass bulb located at the reference line X-X' The two end faces to be connected are abutted and brought into contact to form an abutment contact portion. In b, this abutting contact is heated with a heating flame. While the drive table is rotating from b to c, the rail goes down, the exhaust pipe 1 goes down, and the glass bulb 2
The gap between the two end faces disappears,
The outer diameter of the abutting contact portion increases in proportion to the amount of pressure applied, and heat conduction between the two becomes possible, so that the temperature of the heating portion is balanced. The temperature of the heating flame in c is higher than the temperature of the heating flame in b. During the rotational transition of the drive table from c to d, the rail further descends and the exhaust pipe 1 is pressed against the glass bulb 2, and the outer diameter of the abutting contact part increases by the amount of pressure, and at the same time the outer periphery of the connecting surface becomes almost Connected airtight. The outer diameter of the abutting contact portion, which has become larger at d, is heated to the outer diameter before heating at a. During the rotational transition of the drive table from d to e, the exhaust pipe 1 is further lowered by the rail and pressed against the glass bulb 2. At this point, the connection is airtight almost to the inside of the connection surface. e
During the rotational transition of the drive table from to f, the rail descends and the outer diameter of the abutting contact portion increases. At step f, the power of the heating flame is increased to connect the end face of the exhaust pipe 1 to the end face of the glass bulb 2 by welding. At this time as well, the outer diameter of the connecting portion is transferred to the next g-1 without becoming smaller than the outer diameter before heating at a. During the transition from f to g-1, the shape of the connection is g-
The heating temperature is set at such a temperature that the outer diameter of the connecting portion increases as shown in 1. In g-2, the inner diameter of the connection part is maintained at a temperature at which the connection part is stretched in a state of 1.0 to 1.5 times the inner diameter before heat processing. The rails at g-2 and g-3 are driven up and down, and when the rotary table moves from g-1 to g-3, the rails descend to the height of g-2 and move from g-3 to the next process. At this time, the rail at g-2 rises to the position shown at g-3, that is, the height k of the rail at a, and returns.
As the exhaust pipe 1 is pulled up by the vertical movement of the rail, the connecting portion is stretched as shown in FIG. 4, and a sealed portion of the exhaust pipe 1 is formed. The height of the rail in the process after g-3 is k
It is maintained at the height of

に加熱炎が入り込まず、内部汚染がないので洗浄
などの処理が不要である。 As described above, according to the embodiment of the present invention, when the exhaust pipe 1 and the glass bulb 2 are connected, heat conduction between them is sufficient at the abutting contact portion, so that the exhaust pipe 1 and the glass bulb 2 are connected to each other. This suppresses the rapid temperature rise at the edge of the end face of the exhaust pipe 1.
And reboiling is unlikely to occur in the glass bulb 2. In addition, there is no need to use compressed air, and since the exhaust pipe 1 and the glass bulb 2 are heated with a heating flame after they are brought into contact, the heating flame does not enter the inside of the exhaust pipe 1 and the glass bulb 2. Since there is no contamination, processing such as cleaning is not necessary.
ところで、排気管１とガラス球２の端面同士を
接触せしめてこの接触部を加熱すれば、再沸騰現

け、それらの接続が不確実になる。したがつて、
その接続を確実なものとするためにはガラス管の
内面部も十分な温度となるように同部を加熱する
必要があるが、その結果、同部の径が小さくなつ
てしまう。 By the way, if the end surfaces of the exhaust pipe 1 and the glass bulb 2 are brought into contact with each other and this contact area is heated, it is easy to avoid the reboiling phenomenon, but it is also possible to make the temperature of the inner and outer surfaces of the contact area uniform (to eliminate the temperature difference). ), and their connection becomes uncertain. Therefore,
In order to ensure the connection, it is necessary to heat the inner surface of the glass tube to a sufficient temperature, but as a result, the diameter of the inner surface of the glass tube becomes smaller.
しかし、本発明実施例では排気管１を下降させ

く排気可能とする接続部の内径）も維持できる。 However, in the embodiment of the present invention, the exhaust pipe 1 is lowered to increase the diameter of the abutting contact part and heat the same part, so that the exhaust pipe 1 reaches the inner surface of the abutting contact part.
It is possible to secure time to reach a temperature at which the connection between the glass bulb 2 and the glass bulb 2 is ensured, and also to increase the temperature of the same part. Furthermore, the necessary diameter of the connection between the exhaust pipe 1 and the glass bulb 2 (the inner diameter of the connection that allows the inside of the glass bulb to be efficiently evacuated in the subsequent exhaust process) can be maintained.
次に本発明の具体例を説明する。 Next, specific examples of the present invention will be explained.

ハロゲン電球と同等の成積であつた。 As shown in Fig. 3, an exhaust pipe 1 made of aluminoborosilicate glass with an outer diameter of 4 mm and a wall thickness of 0.8 mm, and an outer diameter of 14.0 mm with an end surface to be connected in advance,
As a result of connecting using glass bulb 2 with a wall thickness of 0.9 mm,
Connected as shown in Fig. 4, the inner diameter of the connecting part of the glass bulb 2 to the exhaust pipe 1 is 1.3 to 1.5 mm, and the wall thickness is 0.82 to 1.5 mm.
A 0.87mm bulb was obtained, which had good external dimensions without causing re-boiling, and also omitted processing such as cleaning after connection.As a result of prototyping and testing of a 12V30/30W halogen bulb, a cleaning treatment was performed. The result was comparable to that of a halogen light bulb using a glass bulb.
