With this construction, an inner pipe 9 is united with an outer pipe 8 by sticking the inner pipe 9 to the outer pipe 8 firmly and a steel pipe to the inside of which the lining pipe 9 to which a bent and spread part is stuck is applied is manufactured simply and easily.

Description

[Detailed description of the invention] A lining tube made of hard vinyl chloride or other processed material or a synthetic resin tube that can be crimped onto the outer tube using heated FE+ is inserted into the outer tube as an inner tube, and the insertion portion from the outer tube is inserted into the outer tube. is easily and strongly pressurized, and in conjunction with the heating process of the outer tube and the inner tube, the insertion portion of the inner tube that faces the outer tube is expanded and bent, and the bent portion is expanded and bent. An object of the present invention is to obtain a manufacturing device for steel pipes, etc., which has a lining pipe made of vinyl chloride or the like that can be adhered to the collar of the outer pipe. The press plate can be freely slid along the rail while the material pipe is interposed, and the press plate can be pulled by attaching a rope to the press plate, or the press plate can be restored with a lining such as vinyl chloride. An example of its implementation is explained as follows (1) is a manufacturing device for steel pipes etc. with pipes inside, and (1) is a rail bent in a U-shape and horizontal sliding parts (JA) on both sides. , Qb) are provided integrally with the support plate (2), which is fixed to one end of the rail (1). (3) is a pressure plate,
The plywood (3C) with both the engagement parts (3a) and (3t+) hanging down is fixed together, and the plywood (3C) is placed on the rail (1) and the engagement parts (3a), ( 3'b) is brought into contact with the sliding parts (la) and (To). The pressing plate (3) can slide freely on the rail (1) (also between the supporting plate (2) and the pressing plate (3)), so that it is possible to insert a material tube to which the lining tube manufacturing means is applied. In other words, the material pipe can also be placed on the rail (1).3 (4) is a rope, one end of which is attached to the suppression plate (3), and the other end is attached to the electric motor (5). The cables (4) to be wound are attached to both sides of the pressure plate (3), and the electric motors (5) are attached to the rolls.
5) The winding for the flea is done by roll threading. (6
) is the trochanter, (7) is the return cable that is wrapped around it, one end is attached with a pressure plate (3), and the other end is wound like a roll equipped with reversing equipment such as a spiral spring. .In the material pipe (
8) is an outer tube, which is usually a steel tube, but is also an outer tube made of a strong material (such as iron) or an outer tube made of other materials. Ha tsuba (抛)
It has. (9) is a lining pipe, which is usually made of hard vinyl chloride, but it does not prevent it from being a synthetic resin pipe that can be subjected to other processing, heating, or pressure bonding. .

(9a) % (9b) shows the bulges formed at both ends of the lining pipe (9), and shows the method of manufacturing the material pipe by inserting the lining pipe (9) into the outer pipe (8), which is a steel pipe. In this case, the outer tube (8) and the inner tube ( 9) A synthetic resin adhesive is interposed between the cleaning parts (9a) and (9b) of the inner pipe (9).
) Attach a fuze closing body, such as a blind collar αQ1 (b), to the end and fix it with a collar fixing means, connect it to a flow pipe (2) that generates air pressure, water pressure, etc., and connect it to the fuse ( To)
, connected to a fluid power source such as a boiler or a compressor, and placing the combination of the outer pipe (8) and inner pipe (9) above the rail (1) is the flow pipe ( 6) Connection (this is the interposed cock, (to) is the collar joint, and the flow pipe @
and the main pipe αη. (g) indicates an aquarium.Also,
Although the heating tank is not shown, it is equivalent to the water tank fζ if shown. α groan is a curved pipe manufactured according to the present invention, (1) is a bolt, (20a) is a nut, (Foundation) is a backing, (2
) indicates <pB right vise) In the present invention, the pressing plate (3),
When implementing the support plate (2), it may be a single rod in some cases, as long as it performs the same function as pressing with a plate. The present invention will be explained based on the above-mentioned embodiment.In the state of the above-mentioned embodiment, the inner tube (9) is statically bonded to the outer tube (8). Inject heated compressed air or pressurized water into the inner tube (9), and move (shake) a large flame around the outside of the outer tube (8) from side to side. Heat the inner tube (9
The outer tube (8) is crimped 1ζ inside the outer tube (8), and the outer tube (8) and the inner tube (9) are thereby adhesively fixed via the adhesive, and the bulges (9a) and (9b) Configure. Then, remove the blind collar αQ, (b) that connects the fluid flow pipe (2), place it on the rail (1), and place the suppression plate (3) on the bulge (Oa) of the inner pipe (9). + Also, the bulge (9a
) If there is no bulge (-) in contact with the insertion part of the inner tube (9) at the negative end of the outer tube (8), if there is no (9b), the inner tube (9) For Iζ, compressed air and pressure water were not introduced in the previous process. ), the inner tube (9
) or the insertion part (same as above) is pressed against the support plate (2), the cable (4) is strongly pulled by the rotation of the electric motor (5), and then pressed from this side. The plate (3) strongly presses the bulge part (9a)% (9b)% or each insertion part,
When expanding them, the bulges (9a), (91:
+) is not formed] If only the sweeping part is formed, the bulges (9,) and (9b) will be formed.If the traction of the cable (4) is removed, the rail (1) can be By placing it at an angle, the pressure plate (3) will automatically return to its original state due to gravity, or if the pressure plate (3) is attached with a return cable (7), if it is moved forward, the pressure plate (3) will return to its original position. 3) will be restored.
When the return cable (7) is connected to the above pressing plate (3), the electric motor (5)
Of course, when being towed by the cable (4) due to the rotation of the inner pipe (9), the inner pipe (9) is moved back in the opposite direction.
It is required to remove the blind collar tool αQ1 (b), the press plate (3), etc. from the swollen part (9a) and (9b).

The outer tube (

(91:,) A means for gluing each part of the flange (Ba) is used as necessary. Also, to give an example of the heated fluid sent to the flow pipe @, the heating tank contains heated compressed air, heated fluid, etc. Glue the inner tube (9) to the inner wall of the outer tube (8) using water, heating oil, steam, etc., or use electric heating equipment for military service, and use the heating material generated by the static heating. When fixing the outer tube (8), heat the outer tube (8).
In addition to heating the outside of the tube (8) with a flame, the outer tube (8) may be stored in a heating tank (it goes without saying that the heated compressed air may be introduced into the inner tube (9) in this stored state). Alternatively, if the same pressure water is supplied or multiple outer tubes (8) are connected, the bulges (Oa) and (gb) are expanded and fixed.
