Abstract
A method and fixture for filled billet packing wherein an entire pack is built up in a single step. Substantially even lateral forces are applied to wires and other elongated members within the billet by inserting filler rods at one or more places along the periphery of the pack.
Claims22
A method for filled billet packing comprising the steps of:
- placing rods within a fixture having a longitudinal axis and inner surfaces defining a substantially symmetric geometric area for accepting said rods therein, wherein said rods are placed in parallel relation to each other and in parallel relation to said longitudinal axis to form a pack, and wherein said fixture is further comprised of a shaping tool having a dugout for defining the shape of said pack;
- placing said rods into said fixture to make contact with said dugout;
- and
- clamping said fixture to apply a force lateral to said longitudinal axis to said pack to compress said pack prior to extrusion.

- placing rods within a fixture having a longitudinal axis and inner surfaces defining a substantially symmetric geometric area for accepting said rods therein, wherein said rods are placed in parallel relation to each other and in parallel relation to said longitudinal axis to form a pack, and wherein said fixture is further comprised of a shaping tool having a dugout for defining the shape of said pack;
- placing said rods into said fixture to make contact with said dugout;
- replacing said rods with dummy rods where said rods do not make contact with said dugout;
- and
- clamping said fixture to apply a lateral force to said pack to compress said pack.
2 more elements
A fixture for filled billet packing comprising:
- a front face, a middle face, a back face, and clamping means for applying a lateral compressive force to said rods;
- and wherein inner surfaces upon said front face, said middle face, and said back face, form a substantially symmetrical geometric area for accepting wires therethrough;
- and
- a shaping tool having a dugout, said dugout defining an area where said rods are placed within said fixture to form a pack.
1 more element
A method of filled billet packing comprising the steps of:
- placing rods within a fixture to form a pack, wherein said fixture has a front face, a middle face, a back face, clamping means for applying a lateral compressive force to said rods, and a shaping tool having a dugout;
- and wherein inner surfaces upon said front face, said middle face, and said back face form a substantially hexagonal area for accepting rods therethrough;
- placing dummy rods within said fixture in one or more places along the periphery of said pack to aid in the build up of said pack, wherein said pack is built substantially cylindrical in shape;
- and
- clamping said fixture to apply lateral force to said pack to compress said pack.
