ABSTRACT:
A method is provided for hydroforming a ring-shaped tubular structure such as a door opening for a vehicle body. The method includes providing a ring-shaped tubular blank having a hollow sealed interior, capturing the ring shaped tubular blank in a hydroforming die cavity, piercing the ring shaped tubular blank with a hollow punch, and introducing pressurized fluid through the hollow punch into the hollow sealed interior to expand the tubular structure to conform with the shape of the hydroforming die cavity and thereby hydroform the ring-shaped tubular structure.
