초록

A process for forming a tubular member is provided which includes a pre-forming process for tube-expanding (bulge) forming and bending forming a tubular material using first and second molds and a final forming process for crush forming a preformed tube using a third mold so as to give its cross section a desired shape, the pre-forming step being carried out using the first and second molds heated at temperatures equal to or higher than the recrystallization temperature of the tubular material and the final forming step being carried out using the third ...

청구항

What is claimed is: 1. A process for forming a tubular member, in which a tubular starting material is formed into a desired shape while applying an internal pressure to the tubular starting material, said process comprising: a step of providing a pre-forming mold having a cavity formed therein and a final forming mold having a cavity formed therein, a pre-forming step of pre-forming said tubular starting material into a preformed tube by setting the tubular starting material into the cavity of the pre-forming mold and clamping the pre-forming mold whil...
