B21D 28/18
B21D 28/28
US Classification:

72 55, 7237026, 294211, 83 53
Abstract:

A center support punch assembly for a hydroforming die includes a center support member for fixed attachment to a die. The center support punch assembly also includes a button disposed about and space from the center support member for fixed attachment to the die. The center support punch assembly further includes a plunger movable relative to the center support member to allow fluid within a tubular member to force a wall portion of the tubular member outward against the center support member and be sheared by the button to produce an opening in the tubular member.

International Classification:

B21D 26/02
B21D 28/28
US Classification:

72 55, 72 58, 72325, 7237027
Abstract:

A double action punch assembly for a hydroforming die includes a first punch segment having an aperture extending therethrough. The double action punch assembly also includes a movable mounting block disposed in the aperture of the first punch segment. The double action punch assembly further includes a plurality of second punch segments connected to the mounting block. The first punch segment is moved in a first action to pierce a tubular member in a first direction and the second punch segments are moved in a second action to pierce the tubular member in a second direction to produce an opening in the tubular member.

International Classification:

B21D 26/02
B21D 28/28
US Classification:

72 55, 72 58, 72 62
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.
