摘要： 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.

摘要： A helical cam device for use with a wide variety of applications generally includes a first cam component, a second cam component and an axial guide. The cam components each have a helical cam track located on an axial end, so that coaxial alignment of the two cam components allows opposing cam tracks to contact and rotate against each other. The helical cam tracks, which are preferably divided into quadrant sections, are designed such that relative rotational movement between the cam components causes a corresponding relative axial movement. According to one embodiment, the axial guide is a cylindrical rod-passing through the center of the cam components; in another embodiment, it is a cylindrical sleeve surrounding the cam components. Moreover, barrel slots, detents and/or truncated peaks can be used to control the travel of the cam components.
