摘要： To form a through hole at one portion of a side wall, of an expanded portion made by plastically deforming one part of a metal tube radially outward, in a portion where the plate thickness gradually changes, a slide tool is withdrawn from inside a punch hole while applying hydraulic pressure to the inside of the side wall. At the instant of commencing withdrawal of the slide tool, the degree of progress in the shearing for the portions of the side wall matching with the two side edges of the punch hole is made different. Then, the timing for moving from shearing to rupture is made to coincide, so that of the side wall, the portions matching with the punch hole, are made reliably into a blank, and are extracted from the side wall.

摘要： A structure and method are provided for forming a through hole at one portion of a side wall of an expanded portion made by plastically deforming one part of a metal tube radially outward, in a portion where the plate thickness gradually changes. A slide tool is withdrawn from inside a punch hole while applying hydraulic pressure to the inside of the side wall. Regarding a tip end face of the slide tool, a portion facing the portion of the side wall where the plate thickness is relatively thick is recessed. At the instant of commencing withdrawal of the slide tool, the degree of progress in the shearing for the portions of the side wall matching with the two side edges of the punch hole is made different. Then, the timing for moving from shearing to rupture is made to coincide, so that of the side wall, the portions matching with the punch hole, are made reliably into a blank, and are extracted from the side wall.

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.
