CONTROLLABLE AND ADJUSTABLE STAMPING DRAW BEAD WITH REVERSE BEAD GEOMETRY

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. Also, the protrusion is adjustable in real-time within the female bead. A stamping machine with the first die component and the second die component has a control unit configured to adjust the protrusion in real-time as a function of mechanical property testing data, width testing data, thickness testing data, lubrication testing data and/or image sensor module data on one or more blanks to be stamped and/or one or more blanks that have been stamped.
