摘要： A method and apparatus for three-dimensionally bending a metal material are provided. A product intermittently having a bent portion which curves three-dimensionally and a quenched portion is manufactured by a bending method which performs bending downstream of a support means while feeding a metal material which is supported by the support means from an upstream side towards a downstream side. A portion of the metal material is heated by a heating means for the metal material downstream of the support means, a bending moment is imparted to the portion of the metal material which was heated by the heating means to carry out bending by three-dimensionally changing the position of a movable roller die which is disposed downstream of the heating means and has a plurality of rolls which feed the metal material which was heated by the heating means in the axial direction, and the metal material is quenched by spraying a cooling medium at the portion of the metal material which was heated by the heating means by a cooling means disposed between the heating means and the movable roller die. Errors in a product due to bending are suppressed by supporting a portion of the metal material which has exited from the movable roller die.

摘要： A profile mother pipe for hydraulic bulging of the present invention has a peripheral length whose outer diameter is gradually increased or decreased from one end to the other end in an axial direction. In the profile mother pipe, a holding portion whose peripheral length is increased toward a pipe end face on one end side can be formed on at least one end side and a parallel portion can be formed on the other end side where the holding portion is not formed. In a working apparatus and method in which the profile mother pipe is used, pressing working can be performed from the pipe end toward the axial direction, even in use of the profile mother pipe whose sectional shape is largely varied in the axial direction. Therefore, an expansion ratio larger than ever before can be obtained in a hydraulic bulged product to which hydraulic bulging is performed.
