Description of the Related Art A curved pipe joint of a round duct joint which is generally used at a piping site is divided into an integral type and a multi-joint type, and the integral type is a tubular type. Two or three are formed by mutual welding etc. at a specified angle. In the multi-joint type, the prescribed pipe is formed by joining several surfaces that are inclined at a predetermined angle and molding it to the desired angle.This is the formation of ∧ and ∧ shapes where the cut edges of the inclined surface are opposite to each other. The joint surface is joined in a slightly circular shape with a polymer joint.

∧形接合は旋回や衝撃に弱く脱落の可能性が強い。At the piping site, the center of the pipe-to-pipe coincides, and the center-to-center error of the pipe-to-pipe is intentionally prepared before the construction work. There is a need for a joint that can accommodate unexpected tube-to-tube center errors. The above-mentioned conventional multi-joint can swivel about the center line perpendicular to the slanted surface, but since it is only a certain angle with respect to the swivel center, it swivels only outward from the center of the pipe to be spliced. Either the error in the center of the tube is extremely small, or it is forcibly joined. or,
The ∧ shaped joint is weak against turning and impact and is likely to fall off.

W 1 and W 2 ) are set by press-pressing and molding, and other divided bodies facing each other are also press-pressed by the same means to form, and the press-pressing two By combining the divisions, the winding folding margins (8, 8 1 , 8 2 ) are arranged on each side, and first, the knockout (11) and the punch (9) facing the punch (9) mounted on the press are pressed down. Curling is performed by these related operations of the blank holder (10), and finally a winding folding margin (8, 8 1 , 8 2 ) is formed on the inner side where the two divided bodies are combined,
With the groove metal mold (12), fold the folding process (14,
14 1 , 14 2 ) and the second stage, and the cut edge portion (7, 7 1 , 7 2 ) having a shape that is horizontally divided into two at the center of the B joint portion (6, 6 1 , 6 2 ). ) Winding and folding allowance (8, 8
No. 1 , 8 2 ) and the contact regions (W, W 1 , W 2 ) are set by press-pressing, and other divided bodies facing each other are also press-pressed by the same means. And the press-divided two-divided body into the A joint portion (1, 1 1 ,
1 2 ) inner spherical body (2, 2 1 , 2 2 ) is covered and united,
Inner spheres (2, 2 1 , 2 2 ) and B joints (5, 5 1 , 5)
2 ) through which a slotted metal mold (12) is fitted, and the overlapped portion of the winding folding margins (8, 8 1 , 8 2 ) is held by a punch (9) with an outer spherical body (4, 4). 1 , 4 2 ) Curling process (13) on the outside, B joint (5, 5 1 ,
5 2 ) is pressed by curling (13, 13 1 , 13 2 ) and then folded by collapsing (14, 14 1 , 14 2 ), and the seam folds are inwardly shaped with a grooved die (12). Molding,
A method for forming a joint for pivoting a joint, comprising the fourth step of forming the other side by the same means.
