Description of the Related Art Adhering a tip of a thin pipe to a target surface is extremely difficult because the adhesion area of the tip of the pipe is very small, and practically, it is hardly practically used. However, theoretically, as shown in FIG. 4, it is conceivable that a flange 2 is formed in advance at the tip of the pipe material 1 and this flange 2 is welded to a target surface.

きる接着方法を提供することである。However, when the flange portion 2 is formed at the tip of the pipe material 1 as described above, the pipe material 1 is manufactured continuously, and the cutting length is determined according to the purpose. Can not. Therefore, there is no other choice but to specify the length of the pipe in advance according to the specific purpose of use and to manufacture the specific pipe individually. If the pipes whose lengths are determined are individually manufactured as described above, the manufacturing cost is too high and cannot be put to practical use. As a result, they are rarely adopted in practice.
SUMMARY OF THE INVENTION An object of the present invention is to provide a bonding method in which a pipe material is continuously manufactured and, after being cut to a required length, can be easily welded to a target surface.

Do not extrude the synthetic resin material with an extruder
In addition, the pipe made of synthetic resin is reduced in diameter by pulling it down.
While molding the material, the end of the pipe material is heated and expanded
Then, the expanded portion is pressed against the heated surface to be bonded and welded.
It is characterized by When a synthetic resin pipe is drawn down by an extruder and sized, when the sized pipe material is heated again, the heated portion expands to the size before the drawing. By pressing the enlarged portion against the heated target surface, the same result as welding the flange portion 2 of FIG. 4 to the target surface can be obtained.

With extruded in an extruder 3 the synthetic resin material, a reduced diameter by pulling it at constant force, line a so-called sizing
The synthetic resin pipe member 1 is formed while the pipe is being formed . Note that reducing the diameter of the pipe member 1 in this manner is referred to as withdrawal. Pipe material 1 sized as above
Is cooled in the cooling water tank 4 and its size is specified.

ておけば、加熱溶融時に穴８が塞がれたりしない。When the end of the pipe material 1 thus manufactured is heated by the heater 5, the heated portion expands while melting, as shown in FIG. The size of the expanded portion 1a formed at this time is approximately the size before the pipe material 1 is pulled down. This is a general property of synthetic resin pipes. The present invention focuses on the above characteristics of the synthetic resin pipe and applies it to the purpose of bonding. The expanded portion 1a that has been heated and melted as described above is pressed against the surface 6 to be bonded.
a further spreads along the surface 6 to be bonded, and becomes a flange shape shown in FIG. A hole 8 communicating with the pipe material 1 is formed on the surface 6 to be bonded. When the expanded portion 1a is pressed against the surface 6 to be bonded as described above, the periphery of the hole 8 is formed. Is heated in advance by a heater (not shown). However, in this case, the pin 9 of the jig 7 is
Is inserted in advance. If the pins 9 are inserted in this manner, the holes 8 are not closed during heating and melting.

Pass the pin 9 inserted into the hole 8 of the bonding surface 6 through the pipe material 1
By doing so, even if the pipe material 1 is thin, its tip is not deformed or closed. The bonding method of this embodiment is as follows.
As described above, the expanded portion 1 formed when the pipe material 1 is heated can be bonded to the surface 6 to be bonded by using the expanded portion 1. Therefore, even if the pipe material 1 is manufactured continuously, it can be cut to a desired length, and its tip can be bonded to the surface 6 to be bonded. In that the pipe material 1 can be manufactured continuously, the manufacturing cost can be greatly reduced. Moreover, even with a considerably thin pipe material 1 , a sufficient bonding area can be secured by the expanded portion 1a , so that the pipe material 1 can be reliably welded to the target surface 6 to be bonded . Further, even if the pipe material 1 is considerably thin, it is not blocked. In particular, the use of the pin 9 can reliably prevent the hole 8 and the pipe material 1 formed on the surface 6 to be bonded from being closed. Furthermore, even if the pipe material 1 is greatly expanded and its welding area becomes large, stable welding can be performed.

As a result, the expanded portion can be formed, so that welding can be accurately performed on the target surface . Since the pipe material can be manufactured continuously, the manufacturing cost can be reduced. Also, by heating the tip of the pipe material, an enlarged portion can be formed at the tip without using a special jig or the like, but the enlarged portion has a size before the pipe material is pulled down. it can. Therefore, even with a thin pipe material, a sufficient bonding area can be secured,
