Yield improvement by reducing the cost discarded pipe end as much as possible, prevent wrinkles due to clamping loaded with internal pressure, multi-step hydroforming and pre-reduction of the tube end machining, mold costs by simplifying the mold mechanism reduction, for the purpose of collecting the hydroformed part is flanged over the entire length. The present invention therefore is fitted with a pipe end of a metal tube in a state of protruding from the lower mold, said metal tube gradually… Expand
