摘要： PROBLEM TO BE SOLVED: To provide a hydrostatic bulging method by which the width of a flange to be formed is worked into a specified size and at small variation, and further, shaft pushing is possible and cracks which are generated in the tip part of the flange are reduced.
SOLUTION: (1) In the hydrostatic bulging method, a rough flange which is thicker than the thickness of a finished flange is formed in the longitudinal direction of a metallic tube in preformation, next, after forming the finished flange by hydraulic bulging or after forming an intermediate flange and the finished flange, a product having a closed cross section is finished by increasing the hydraulic pressure. (2) In a hydrostatic bulging die, a surface opposing to the flange which is formed on the metallic tube to be housed is composed of a vertical wall and at least the tip part of the finished flange is brought into contact with the vertical wall.
