ABSTRACT:
A raw material delivery system is disclosed. It is used with a press of the type used to compact raw material in a die. The press has a horizontal table with an opening in which the die is held. A feed shoe is movable across the table between an extended position where a central bore of the feed shoe overlies the die and a retracted position where the central bore is aligned with a bore in a bridge. A vertically movable feed tube is carried on the bridge, and has a passage through which raw material may pass. The vertically movable feed tube receives raw material from a vertically fixed feed tube received telescopically within the vertically movable feed tube. A valve is between the two feed tubes. A valve may be provided between the bridge and the feed shoe so that the raw material passes through this interface without being exposed to cross-ventilation. The vertically movable feed tube may be pivotally connected to the bridge so that the movable feed tube may be pivoted away from the bridge opening when it is desired to change the metal powder or the die. Both the fixed and movable feed tubes may be heated, and heated material may be received by the fixed tube.
