Latest Patents

Miller’s recent patents address techniques for managing sheet material as it is shaped.

“Stamping Machine and Method Including Variable Binder Gap” describes a machine that uses upper and lower binders, a punch, two cylinders, and a cushion pin to control when the binders’ teeth engage the sheet. The arrangement applies forces in a defined relationship and supports post-stretching, helping prevent or minimize springback.

“Stamping Apparatus Having a Part-Time Draw Bead” describes a staged stamping process. A draw bead first engages the blank to begin stretching it, then disengages as the blank moves toward the drawing punch. A stake bead engages in the final stage to tighten the material around the punch and form the finished shape.
