Abstract
A forming die includes a first die component with a male bead and a second die component with a female bead. The male bead and the female bead form a bead with a reverse bead geometry with the male bead having a groove and the female bead having a protrusion complimentary with the groove such that the protrusion is aligned with the groove when the male bead extends into the female bead. The male bead includes a push surface, a pair of sidewalls extending from the push surface to a main surface of the first die component, and the groove extends inwardly into the rib. And the female bead includes a stop surface and a pair of sidewalls extending from the stop surface to a main surface of the second die component, and the protrusion extends outwardly from the stop surface into the female bead.
