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.

摘要： PROBLEM TO BE SOLVED: To prevent occurrence of a defective phenomenon in which an aperture between an inner pipe and an outer pipe at a bend portion becomes wider in the inner periphery side of the bend while it becomes narrower in the outer periphery side. SOLUTION: In the manufacturing method of the double walled pipe member, a hydraulic bulging machine is employed, which has a metal die set comprised of a first die 11 that has the bend portion and an inner surface at least partially contacted with an outer periphery side of the bend of the outer pipe 2a at the bend portion of the double walled pipe workpiece 2 structured by the inner pipe 2b and the outer pipe 2a, and a second die 12 to form the double walled pipe workpiece 2 into the desired profile. After the double walled pipe workpiece 2 is set in the first die 11, a fluid is introduced into the inner pipe 2b and the aperture between the inner pipe 2b and the outer pipe 2a, while in the bend portion the inner pipe 2b is fixed via the outer pipe 2a by the first die 11 and restrained from shifting toward the outer periphery side of the bend of the inner pipe 2b at least during a first process. Then, in the second die 12, the outer pipe 2a of the double walled pipe workpiece 2 is bulged inside the second die 12 and formed into a product profile. The aperture between the inner pipe and the outer pipe becomes uniform not only in the straight portion but also in the bend portion. COPYRIGHT: (C)2004,JPO&NCIPI
