  • Method of forming a flanged tubular member in hydroforming
    Patent number: 8171769
    Abstract: A method of forming a flanged tubular member includes the steps of: positioning a tubular blank in a die; applying nominal pressure; closing the dies; and increasing pressure within the blank, thereby converting the tubular blank to a hydroformed member having the flange and a hem with a cavity therein. The die halves define: a die tubular cavity portion; a die hem cavity portion; and a die flange cavity portion. Upon closing the die halves with nominal pressure and then increasing pressure, (1) the blank is deformed within the die tubular cavity portion; (2) the flange is defined from a portion of the blank in the die flange cavity portion; and (3) at least an intermediate hem is defined in the die hem cavity portion.
