Abstract

PURPOSE:To produce a tee pipe joint easily in a large amt. in the stage of producing the tee pipe joint with two pipe material, by inserting insertion jigs into a straight pipe having a hole for insertion of a branch pipe, inserting the brach pipe fitted with an outside guide into said hole in the straight pipe and forcing the pipe strongly. CONSTITUTION:In the stage of producing a tee pipe joint consisting of a straight pipe 2 and a branch pipe 1, a hole 3 into which the end part of the pipe 1 can be inserted is pierced beforehand on the outside surface of the pipe 2. Insertion jigs 4 provided with guide grooves 4a are inserted into the pipe 2 from both ends and are so positioned that the grooves 4a come right under the hole 3. An outside guide 5 is fitted onto the pipe 1, and the branch pipe is inserted into the hole 3 while the forward end 5a of said guide has a margin as much as to allow the formation of a pleat 6. The guide 5 is pressed to flare the forward end of the pipe 1 like a funnel 7 along the guide grooves 4a of the jigs 4 and to form the pleat 6. The branch pipe is adhered together with the funnel-like flared part 7 to the straight pipe 2, whereby the tee joint is formed easily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for easily manufacturing a T-shaped pipe embroidery using two pipe materials.It is used for water piping, electrical piping, construction metalwork, etc. T-shaped Iig hand manufacturing methods include bulge processing method, press processing method, pipe per cylinder and #
There are four types of manufacturing methods, such as the combination method with contact and the melting method, but these manufacturing methods have advantages and disadvantages.In view of this, the present invention is suitable for large violet production, and is inexpensive.
Il construction and airtight as necessary4! This was done to slow down the production of l5vc.

The present invention will be explained below based on the illustrated embodiments. In the figures, pipe materials forming a τ-shape 11Fl11 for 1st and 2nd companies, respectively, and the required diameter, wall thickness, length, and material are shown. One side is a branch pipe 1, and the other side is a straight pipe 2. and ζO min#&w
1 and straight pipe 2 may have the same diameter or ^ diameter, and it is preferable that they are made of the same material as KIlliilF, but it is possible to connect them as all members.And the above straight pipe 20 minute branch To join 11F1, drill a hole St having a diameter that allows the end of branch IIF1 to be inserted into the electrodeposited position. This can also be done by using perinder processing. Next, insert the branch pipe 1 into the hole 3 of the straight pipe 2. In this case, insert the branch pipe 1 into the straight pipe 2 at both ends.) Insertion jig: 4. ,,,4 is inserted (0ζ
O Insertion Jig A4 They are inserted into the straight pipe so that their tips are in contact with each other at the center position of the hole s, and in both inserts #44, the tip of the branch f1 is inserted in the outer circumferential direction, that is, radially, at the hole SO position. Guide that bends and expands in the direction #
The outer guide 5 is held on the outer periphery of the outer guide w1, but at this time, Ii6 is formed between the tip 5a of the outer guide 5 and the outside of the straight pipe 2. The outer skin of the branch tube 10 is held in the line drawing so that it has *11i1 fibers. It is also possible to install the branch pipe 1 using this guide by inserting the branch pipe into the hole of the straight pipe.
In this case, the length required to form the fold 6 between the tip of the outer guide and the tip IIIF of the branch pipe, di the thickness of all,
It is assumed that it is the sum of the enlarged and bent portions 7 at the tip.

Next, when the outer guide is expanded and pressed with the required pressure, the tip of the branch f1 is expanded into a clapper shape along the guide binding 4a of the insertion jig, and the expanded bent portion 7 When the outer guide is further pressed, the tip of the branch tube is supported by the insertion jig and the insertion of the branch tube is stopped. However, due to this pressing force, the branch tube between the tip of the outer guide and the dif outer m surface is moved in the outer circumferential direction. Glue is drawn out, and then, at the outer guide tip 5a, which is processed to form 116, it is leaked along the outer periphery of the hole 3 of the tie and becomes @6 ◎ζK) @6 and expanded and bent. The hole edge of the straight pipe is strongly clamped by the part 7 from the inside and outside, and the branch w1 is joined with ** 2 K111, and the OT shape is formed.
When the 11111 hand is manufactured, the 4116 is formed when the 9-branched bud is forcefully inserted and pressed directly into the ttm with the JII held in the 0 Shojokigai guide, but the branch pipe is made to ensure that the lint and rays are formed. An inner guide may also be inserted within 1.

The above 0IIll manufacturing method is slightly inferior in airtightness *
*When used in water supply or piping systems When weighing, hold the above puffing material in place to make an airtight 1m meter.
This backing material is made of leather, synthetic rubber, synthetic resin, or other materials that can be used as a backing, but if heat resistance, chemical resistance, etc. are required, J6 metal materials such as silver are used. 0 Ushida Rusui and other materials were formed into a bundle, a plate, or a ring in the same manner as the above backing material.
At the time of pressure deviation, - and the straight pipe outer layer surface tm are interposed, and both pipes are joined -
1 Heat this to dissolve the easy-to-understand materials in the bath, and let them flow into the first gate at the joint of both pipes to join them together in an airtight manner. First, in branch #1, pre-process @6tm-beadinder at the specified position of the above-mentioned branch pipe into the directly operated hole on the insertion surface (0, and then guide II & buds to the outside. The insertion jig is stretched out and the tip of the branch ``C'' is inserted into the directly held hole by forcefully inserting and press-welding it (
It is also possible to produce the T character 'tm+.

According to the present invention, two pipe materials are used and a jig,
By using the guide, the T-shaped tIII handle can be easily and easily formed, and it has the advantage that it can be provided at a low cost and can be easily constructed into an airtight structure depending on the application.
