- FIG. 4 is a right end view of FIG. 3
- FIG. 5 is a plan view
- FIG. 6 is a bottom view.
- the virtual line indicates that the angle of the pipe 4 with respect to the flange 3 can be freely set, and that the flange 3 can be rectangular in plan view.
- the flange joint is manufactured, for example, through the steps shown in FIGS.
- L-shaped tubing with 9 D (R is radius, D is pipe diameter).
- This pipe material 10 is placed in a pipe clamp mold 11, and the first forming mold 13 is lowered to the pipe end 12, and the bending angle R of the L-shaped pipe 10 is set to 0.5 D or Correct the angle to the corresponding angle.
- a hole 11a is formed in the pipe clamp mold 11 in a horizontal direction.
- the horizontal portion 5 of the L-shaped tube 10 is supported by the hole 11a, and the other end of the tube 10 is erected upward.
- the portion corresponding to the outer corner of the L-shaped tube 10 of the pipe clamp mold 11 is formed so as to conform to the curvature R1 of the outer corner of the tube 10.
- an inner hole 13 a having an inner diameter substantially the same as the outer diameter of the tube 10 is formed, and the L-shaped tube 10 at the opening of the inner hole 13 a is formed.
- the portion corresponding to the inner corner is formed so as to conform to the curvature R 2 of the inner corner of the tube 10. After the correction, remove the first mold 13.
- the flange 14 is fitted to the pipe end 12 and the second mold 15 is lowered.
- the tube end 10 is pressed to the groove 2 ′ of the pipe connection hole 2 of the flange 14 by pressing the tube 10 outward by the lower end protrusion 16 a of the second mold 15.
- the tube 10 is fixed in the connection hole 2 so as not to rotate.
- the tube end 12 is inserted into the groove 17 of the second mold 15 to expand the tube end 12.
- the second mold 15 includes a projection 16a having a diameter slightly larger than the inner diameter of the tube 10 and a base end 16b having a diameter larger than the inner diameter of the tube 10.
- the projection 16a is the second component It protrudes from the reference surface of the mold 15 (the contact surface with the flange 14), and has an enlarged groove 17 around the base end 16b.
