Abstract
A filler cam assembly for use with a forming die generally including a center cam component, end cam components and a base assembly and being designed to transition between unloading and forming positions. The various cam components preferably have axial ends with helical surfaces such that rotation of one of the cam components causes a corresponding axial movement of an adjacent cam component. Some features of the filler cam assembly include removable work steels, standardized cam components, drive and lock out mechanisms, and being able to form negative angles, multiple corners and edges, and an entire formable periphery of a metal work piece in a single forming operation, to name but a few.
