Abstract: A stamping tool for forming a stamped metal panel used as part of a pillar of a motor vehicle is provided. The stamped metal panel is arcuate and has a u-shaped cross-section, the arcuate panel including a transitional portion so as to avoid a die lock condition. The tool includes an upper die, and a lower die, and transitional portion surfaces. The transitional portion surfaces tapers as the transitional portion surface extends from the ends of respective upper and lower dies to a first point. The transitional portion is substantially tangential with at least the first wall surfaces of the dies to facilitate removal of the panel from between upper and lower dies of a stamping tool.

Abstract: A stamped metal panel used as part of a pillar of a motor vehicle includes a main wall, an outer side wall, an inner side wall and a transitional portion. The outer side wall extends from one side of the main wall. The inner side wall extends from an opposite side of the main wall and forms a generally U-shaped cross section with the main wall and the outer side wall. The inner side wall has a first wall that extends from the main wall and a second wall that extends from an end of the first wall opposite from the main wall. The transitional portion extends arcuately between the first wall and the second wall. The transitional portion is substantially tangential with at least the first wall of the first side wall to facilitate removal of the panel from between upper and lower halves of a stamping tool.
