摘要： PROBLEM TO BE SOLVED: To prevent the breakage to be generated during the hydraulic bulging of a product deformed metallic bend whose bulged part is bent in the longitudinal direction by forming a part of a straight metallic tube on the outer circumferential bending side of the metallic bend to be of bellows in the axial direction of the pipe. SOLUTION: A deformed stock tube 20 comprises a bellows part 20a and a straight part 20b, and the bellows part 20a is provided at the position corresponding to a bent part of a bend, and an A"-A" section passing a top part (b) of the bellows shape and a C"-C" section on the opposite side across the axis (a) correspond to the section on the outer circumferential side and the inner circumferential side of the bent part of the respective bends. Bellows is not provided on the whole circumference of the tube, but on the A"-A" section subject to the tension in the axial direction during the bending. The deformed stock tube 20 can be manufactured through the hydraulic bulging. The dissimilar stock tube 20 is bent to form a bent metallic tube so that its bellows part is the outer circumferential part of the bend, stored in a pair of upper and lower die grooves, and the hydraulic pressure is applied thereto from the inside, and at least the bent part of the metallic bend is bulged to the prescribed section.

摘要： PROBLEM TO BE SOLVED: To reduce the friction force between a material and a tool, to restrict the buckling and to easily execute a hydraulic bulging of a thin wall tube by executing a preliminary working to preliminarily bulge a range longer than a bulge scheduled length in the axial direction of a metal tube, and compressing the preliminarily bulged part in the axial direction of the metal tube. SOLUTION: A blank tube is inserted in a 2nd axial pressing tool inner shell 84c guided with a lower holder guide groove 81a, and it is positioned with a 1st axial pressing tool 86. Next, a 2nd axial pressing tool 83 on the left is advanced and a die hole space longer than the length of a bulged part of a product is formed between the above and a right side 2nd axial pressing tool 84. Further, a left side 1st axial pressing tool 85 is advanced, brought into close contact with both end faces of the blank tube and it is sealed, an upper holder 82 is lowered, pressed to a lower holder 81, a hydraulic liquid is injected inside the blank tube and the state before preliminary bulging is made. Here, because the blank tube nearby both ends are held with the 2nd axial pressing tools 83, 84, the lengths of the upper and lower holders 81, 82 is made shorter than the length of an upper and lower dies of a conventional method.

摘要： PURPOSE:To efficiently manufacture the title dissimilar metallic pipe joint with different inside and outside dia. by enlarging or reducing the dia. of a double clad pipe from a pipe end to the optional position and forming the double clad pipe with the different dia. and cutting and removing inner layer material of the small dia. part side and outer layer material of the large dia. part side, etc., of the pipe. CONSTITUTION:The double clad pipe and a double clad rod are cut out to the prescribed length and the dias. thereof are enlarged or reduced from one ends up to the optional positions thereof. In dia. enlarging work, in case of the double clad pipe 3, a plug 4 is inserted into the inner layer material 1 and the outer layer material 2 and pushed-in up to the middle thereof. In case of the double clad rod, a wedge-shaped plug is pushed-in up to the middle thereof. In dia. reducing work, the double clad pipe 3 is pushed in a die 5 up to the middle thereof. The prescribed parts of the inner layer material and the outer layer material are then machined and removed and the straight pipe type dissimilar metallic pipe joint consisting of the inner layer material at the one end side and the outer layer material at the other end side and having the same inside and outside dia. extending over the joint entire length or the different dia. type dissimilar metallic pipe joint having the different inside and outside dia. from the joint central part is formed. By this method, the dissimilar metallic pipe joint is manufactured efficiently.
