Abstract: A system for forming a steel material includes a first binder, a second binder, a punch and a carrier blank. The first binder and the second binder are configured to form a draw bead shape in the steel material by compressing the steel material between a draw bead protrusion and a draw bead channel. The punch is configured to form the steel material relative to the first binder and the second binder. The carrier blank is positioned on a surface of the steel material and is configured to cover a portion of the draw bead shape during formation of the draw bead shape in the steel material.

Abstract: Sheet metal forming is a manufacturing process in which flat sheet metal is drawn into a die cavity to form a product shape. Draw-in amount is the single most important stamping index that controls all forming characteristics (strains and stresses), formability failures (splits, wrinkles) and surface quality (distortions) on a panel. Adaptation of a new die set for repetitively stamping sheet metal parts to a part design specification is simplified by using a math-based simulation of the stamping operation under specified engineering stamping conditions for the specified part. The stamping simulations are used to create an engineered draw-in map comparing selected locations on the peripheral edge of the stamped part with corresponding locations on the peripheral edge of its original sheet metal blank.
