摘要
A hydro-forming tool for use in a method of forming a blank into a liquid filled chamber. The chamber is formed by a container ring and a moveable wall that together define a variable volume chamber for containing the liquid. The wall is moveable relative to the container ring to provide a chamber in which the volume of liquid required to back up the blank is minimized. The liquid reduces friction at the chamber entry rim. Liquid may be ported through a counter punch to hydro-form the blank into the detail forming areas.
