Abstract: A forming tool has an upper portion composed of an upper forming die arranged between a first clamping element and a second clamping element, and a lower portion composed of a lower forming die arranged between a third clamping element and a fourth clamping element. The first clamping element and the third clamping element cooperate to exert a first clamping force on a workpiece; and the second clamping element and the fourth clamping element cooperate to exert a second clamping force on the workpiece. The upper forming die cooperates with the first and second clamping elements and the lower forming die cooperates with the third and fourth clamping elements to exert a lateral force on the workpiece when the first and second clamping forces are being exerted on the workpiece and when a vertical compressive force is being exerted upon the upper forming die and the lower forming die.

Abstract: In accordance with various embodiments, methods and systems are provided for designing a bead tool and a bead for sheet metal forming. In one embodiment, a method includes: storing, in a datastore, a library of bead tool data associated with a plurality of bead tools; receiving, by a processor, a plurality of parameters associated with at least one of a punch and a die of a desired bead tool; computing, by the processor, bead tool data for at least one of the punch and the die of the desired bead tool based on the plurality of parameters; providing, by the processor, a subset of bead tool data from the library of bead tool data; receiving, by the processor, a selection of bead tool data from the subset of bead tool data and the computed bead tool data; and generating, by the processor, bead geometry data based on the selection and the bead tool data associated with the selection.
