Hydroforming Using High Pressure Pulsation During Fluid Intensification Cycle

摘要

A method and apparatus for hydroforming a metal part includes placing a part to be formed ( 510 ) within a die ( 512 ), closing the die to enclose the part to be formed, and introducing a high pressure fluid to an interior of the die for expanding the part against an interior surface of the die. The high pressure fluid has a pulse applied thereto for increasing a material flow of the part within the die.
