Combination tool for edge-folding and cutting a panel rim

A combination tool for edge-folding and cutting a rim of a panel, comprising:

• a tool holder frame;
• a cutting blade that is fixedly secured to said tool holder frame so as to be immovable relative to said tool holder frame, and that includes a blade body and a cutting edge protruding away from said tool holder frame;
• an edge-folding tool that is movably mounted to said tool holder frame so as to be linearly slidable relative to said tool holder frame in a linear stamping direction, and that includes an edge-folding tool body and a stamping face protruding away from said tool holder frame proximate to said cutting edge;
• and
• a biasing device that is interposed between said tool holder frame and said edge-folding tool to apply a biasing force between said tool holder frame and said edge-folding tool which urges said edge-folding tool to protrude away from said tool holder frame in said linear stamping direction;
• wherein said tool holder frame has a receiver chamber therein, at least a portion of said blade body is received and secured in said receiver chamber, a guided end portion of said edge-folding tool body is slidingly received and guided in said receiver chamber, and said biasing device is arranged in said receiver chamber between said edge-folding tool body and an end wall of said tool holder frame bounding said receiver chamber.

• and
• a biasing device that is interposed between said tool holder frame and said edge-folding tool to apply a biasing force between said tool holder frame and said edge-folding tool which urges said edge-folding tool to protrude away from said tool holder frame in said linear stamping direction;
• wherein said cutting edge is a one-sided tapered cutting edge formed by an intersection of a flat planar surface of said blade body extending along said linear stamping direction and a taper surface opposite said flat planar surface, with a taper angle of said cutting edge formed between said taper surface and said flat planar surface;
• wherein said stamping face extends at a stamping face angle relative to a planar side surface of said edge-folding tool body that extends along said linear stamping direction and that is in sliding contact along said flat planar surface of said blade body;
• and
• wherein said taper angle of said cutting edge and said stamping face angle of said edge-folding tool are complementary to each other so as to sum together to 90°.

An apparatus comprising a combination tool for edge-folding and cutting a rim of a panel, and a mold adapted to mold said panel thereon,

• wherein said combination tool comprises:
• a tool holder frame;
• a cutting blade that is fixedly secured to said tool holder frame so as to be immovable relative to said tool holder frame, and that includes a blade body and a cutting edge protruding away from said tool holder frame;
• an edge-folding tool that is movably mounted to said tool holder frame so as to be linearly slidable relative to said tool holder frame in a linear stamping direction, and that includes an edge-folding tool body and a stamping face protruding away from said tool holder frame proximate to said cutting edge;
• and
• is a biasing device that is interposed between said tool holder frame and said edge-folding tool to apply a biasing force between said tool holder frame and said edge-folding tool which urges said edge-folding tool to protrude away from said tool holder frame in said linear stamping direction;
• and
• wherein said mold comprises:
• a mold body with a main mold surface on which said panel is molded, an undercut shoulder surface adjoining and being undercut relative to said main mold surface, and a margin compression surface adjoining and extending at an angle from said undercut shoulder surface;
• and
• a cutting counter anvil that is inset into said mold body at a junction of said undercut surface and said margin compression surface;
• and
• wherein said combination tool is arranged and oriented relative to said mold such that said edge-folding tool reaches under said undercut shoulder surface, said stamping face presses a margin of said panel against said margin compression surface and said cutting edge of said cutting blade cuts through said margin of said panel against said cutting counter anvil while pressing said panel against said undercut shoulder surface.
