SOLUTION: Tube end holding dies 12a, 12b are arranged in one end part of die main bodies 11a, 11b. A sealing tool 13 on the side of the tube end holding die is inserted between the tube end holding dies 12a, 12b to hold one end part of the reducing tube stock TP2 together with the tube end holding dies 12a, 12b. A sealing tool 14 on the side of the die main bodies is inserted between the other end parts of the die main bodies 11a, 11b to hold the other end part of the reducing tube stock TP2 together with the die main bodies 11a, 11b. An elastic member 15 for imparting thrust force in the direction of one end part of the tube end holding dies 12a, 12b is provided between the die main bodies 11a, 11b and the tube end holding dies 12a, 12b.

摘要： PROBLEM TO BE SOLVED: To attain a larger pipe expansion ratio than before by enabling a pushing process from a pipe end in the axial direction.
SOLUTION: A deformed pipe as manufactured 11 for bulging has its outer diameter and circumference gradually increasing or decreasing from one end to the other end in its axial direction. A parallel portion 11a or 11b is formed at least on one end of the pipe. Even in the case of the hydrostatic bulging of a deformed pipe of which cross sectional shape changes like a tapered pipe, a larger pipe expansion ratio than before is attainable due to the feasibility of giving an axial push as well as an internal pressure. Further, connection with other component or inserting connection can be facilitated.

摘要： PROBLEM TO BE SOLVED: To provide a structure and a method capable of stably and inexpensively performing an operation to form a through-hole 5c in a part of a side wall 14 of a swelled part 7a formed by plastically deforming a part of a metallic tube 3 outwardly in the radial direction where the thickness is gradually changed. SOLUTION: A slide tool 13b is evacuated into a blanking aperture 12a while applying the hydraulic pressure to the inner side of the side wall 14. In a front end face 20a of the slide tool 13b, a portion facing a part of the relatively large thickness of the side wall 14 is recessed. The advancing degree of the shearing work of a part to be matched with both side edges of the blanking aperture 12a out of the side wall 14 is discriminated at the instance when the slide tool 13b is started to evacuate. By matching the timing from the shearing to the breakage with each other, a portion to be matched with the blanking aperture 12a out of the side wall 14 is reliably formed in a punched piece 10c, and blanked from the side wall 14.
