摘要： PROBLEM TO BE SOLVED: To provide a hydro-piercing method which can properly prevent the overrun of an axis push and can form a pierced hole of high dimensional accuracy. SOLUTION: The invention relates to the hydro-piercing method in a hydroforming process. In the method, a metal pipe is held by a pair of molds equipped with a piercing punch, and working fluid supplied into the pipe is pressurized while pushing the pipe in an axial direction with a pushing tool from both ends of the pipe. The feature of the invented hydro-piercing method is that the pushing tool on at least one end of the pipe is not advanced in the axial pushing direction during piercing by the piercing punch. To be specific, the axial pushing cylinder can be equipped with a mechanical stopper, the control sequence of hydro-piercing can be improved or the structure of the axial pushing cylinder can be made to balance with the pressure fluctuation of the working fluid.

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： In a method of manufacturing a hollow rack shaft, an approximately rectangular plate having a wide rack tooth portion, is bent lengthwise into a gutter-like cross section to provide: at the central portion, a flat bottom portion on which rack teeth are formed later and a pair of mutually facing leg portions, and, in the vicinity of both ends, a semicircular bottom portion and a pair of mutually facing leg portions. The mutually facing leg portions at the central portion have a larger clearance than the clearance of the mutually facing leg portions in the vicinity of both ends. The rack teeth are then formed on the flat bottom portion through the plastic flow of the flat bottom portion and a part of material of the pair of leg portions of this flat bottom portion. The gutter-shaped plate, on which the rack teeth have been formed, is then formed into a tube having a hollow inner surface, by bending the plate and butt joining the edge portions.
