摘要： A process is provided for producing a hollow member having a wall thickness, in a cross section orthogonal to the longitudinal direction, that varies in the longitudinal direction, the process including a heating step of heating a tubular material (Pa) so that the tubular material (Pa) is given a temperature variation in the longitudinal direction, and a stretching step of axially stretching the tubular material (Pa) that has been heated in the preceding step. In this way, a hollow member having a cross-sectional wall thickness that is variable in the longitudinal direction can be easily produced.

摘要： A process for forming a tubular member is provided which includes a preforming process for tube-expanding (bulge) forming and bending forming a tubular material (Pa) using first and second molds (M1, M2) and a final forming process for crush forming a preformed tube (Pc) using a third mold (M3) so as to give its cross section a desired shape, the preforming being carried out using the first and second molds (M1, M2) heated at temperatures equal to or higher than the recrystallization temperature of the tubular material and the final forming being carried out using the third mold (M3) heated at temperatures equal to or lower than the recrystallization temperature of the tubular material. The process enables a tubular material of aluminium alloy to be formed into a tubular member of high precision and high quality which has expanded portions as well as bent portions and whose cross section varies across its length. The process also enables drastic increase in productivity.

摘要： A bulging apparatus has a heating station, a tube expanding station, a preforming station, and a main forming station. A straight tube as a workpiece is gripped by first holding mechanisms or second holding mechanisms, and delivered between the stations as the first holding mechanisms or second holding mechanisms are displaced. During a preforming process and a main holding process, both the first holding mechanisms and second holding mechanisms can be lifted and lowered vertically and can be moved horizontally.
