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.
Claims60
A filler cam assembly for use in forming a work piece, comprising:
- a first cam component having a main body portion and at least one axial end with a helical surface;
- a second cam component having a main body portion and at least one axial end with a helical surface;
- and
- a base assembly having a nest for receiving said first and second cam components such that said helical surfaces operably contact one another, wherein rotation of said first cam component causes a corresponding axial movement of said second cam component.
A filler cam assembly for use in forming a work piece, comprising:
- a center cam component having first and second axial ends;
- a first end cam component having an axial end;
- a second end cam component having an axial end;
- and
- a base assembly having a nest for receiving said cam components such that said center cam component first axial end and said first end cam component axial end operably contact one another, and said center cam component second axial end and said second end cam component axial end operably contact one another,
- wherein rotation of said center cam component causes said first and second end cam components to axially extend towards first and second corners of the work piece, respectively, such that the first and second corners can both be formed in a single forming operation.
A filler cam assembly for use in forming a work piece, comprising:
- a first cam component having a removable work steel mounted thereon and at least one axial end;
- a second cam component having a removable work steel mounted thereon and at least one axial end;
- and
- a base assembly for receiving said first and second cam components such that said axial ends operably contact one another, wherein said removable work steels each includes a shaped surface for contacting the work piece during the forming operation.
A multi-filler cam assembly for use in forming a work piece, comprising:
- a first filler cam assembly, comprising:
- a first cam component having at least one axial end;
- and
- a second cam component having a side mating surface and at least one axial end for operably contacting said first cam component axial end, wherein rotation of said first cam component causes a corresponding axial movement of said second cam component;
- and
- a second filler cam assembly, comprising:
- a third cam component having at least one axial end;
- and
- a fourth cam component having an end mating surface and at least one axial end for operably contacting said third cam component axial end, wherein rotation of said third cam component causes a corresponding axial movement of said fourth cam component;
- and
- wherein said end mating surface of said fourth cam component mates with said side mating surface of said second cam component such that said first and second filler cam assemblies may both participate in a single forming operation.
