Abstract
Abstract A powder compacting apparatus comprising a punch and die assembly having a die plate provided with at least a pair of rows of die cavities and with a reciprocable punch disposed in each die cavity. A work station positioner angularly movable across the upper surface of the die plate carries a station positioner block in which are formed a powder dispenser for each die cavity, an anvil surface for each row of die cavities and a pickup head for each die cavity. The powder dispensers and the pickup heads are disposed in rows corresponding to the rows of die cavities such that each row of powder dispensers, each anvil surface and each row of pickup heads are sequentially positioned, in timed relationship with the reciprocation of the punches, over each row of die cavities for filling the die cavities with powder material by means of the powder dispensers in a first angular position of the station positioner, compacting the powder material in each die cavity between the punch ends and the anvil surface in a second position of the station positioner and ejecting the compacted articles from the die cavities into the pickup heads in a third angular position of the station positioner.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
266 words
An apparatus for making an article of compacted powder material comprising a die plate having at least a first and a second die cavity adapted to be filled with powder material, said first and second die cavities being transversely spaced a given distance; a station positioner block transversely movable over said die cavities; at least first and second separate powder dispenser means integrally formed in said block for filling each die cavity with said powder material when said bloCk is in a first transverse position; at least first and second separate anvil surfaces integrally formed in said block and each adapted to be placed over said first and second die cavities respectively when said block is in a second transverse position; compacting means in each of said die cavities for compacting said powder material in each die cavity against one of said anvil surfaces to form said article when said block is in said second transverse position; and at least first and second separate pickup means integrally formed in said block for picking up said article ejected from each die cavity when said block is in a third transverse position, wherein said second powder dispenser means, second anvil surface and second pickup means are respectively spaced from first powder dispenser means, first anvil surface, and first pickup means by said given distance, such that said second powder dispenser means, second anvil surface, and second pickup means are positioned sequentially over said second die cavity simultaneously with the sequential positioning of said first powder means, first anvil surface, and first pickup means over said first die cavity.
Claim 2
Independent Claim
266 words
An apparatus for making an article of compacted powder material comprising a die plate having at least a first and a second die cavity adapted to be filled with powder material, said first and second die cavities being transversely spaced a given distance; a station positioner block transversely movable over said die cavities; at least first and second separate powder dispenser means integrally formed in said block for filling each die cavity with said powder material when said bloCk is in a first transverse position; at least first and second separate anvil surfaces integrally formed in said block and each adapted to be placed over said first and second die cavities respectively when said block is in a second transverse position; compacting means in each of said die cavities for compacting said powder material in each die cavity against one of said anvil surfaces to form said article when said block is in said second transverse position; and at least first and second separate pickup means integrally formed in said block for picking up said article ejected from each die cavity when said block is in a third transverse position, wherein said second powder dispenser means, second anvil surface and second pickup means are respectively spaced from first powder dispenser means, first anvil surface, and first pickup means by said given distance, such that said second powder dispenser means, second anvil surface, and second pickup means are positioned sequentially over said second die cavity simultaneously with the sequential positioning of said first powder means, first anvil surface, and first pickup means over said first die cavity.
Claim 3
Dependent Claim
102 words
The apparatus defined in claim 1 wherein each of said powder dispenser means comprises a bore in said block normally filled with powder material, said bore having an aperture in the bottom surface of said block aligned with one of said die cavities when said block is in said first transverse position so as to fill each of said die cavities with said powder material, and each of said pickup means comprises an aperture formed in a recessed portion of the bottom surface of said block aligned with one of said die cavities when said block is in said third transverse position.
Claim 4
Dependent Claim
208 words
The apparatus defined in claim 1 wherein said die plate has at least a first plurality of die cavities arranged in a first array and a second plurality of die cavities arranged in a second array, said first plurality of die cavities being spaced from said second plurality of die cavities by said given distance; said station positioner block comprising a first and second pluralities of dispenser means disposed similarly to said first and second arrays and aligned with said first and second plurality of die cavities to fill same with said powder material when said block is in said first transverse position; said first plurality of dispenser means being spaced from said second plurality of dispenser means by said given distance, said first and second anvil surfaces of said block being placed over said first and second pluralities of die cavities when said block is in said second transverse position; said first and second pluralities of pickup means being disposed in said block similarly to said first and second arrays and aligned over said first and second pluralities of die cavities when said block is in said third transverse position, said first and second pluralities of pickup means being spaced from each other by said given distance.
Claim 5
Dependent Claim
55 words
The apparatus defined in claim 3 wherein said first plurality of die cavities in said die plate are arranged in a spaced, straight line configuration forming a first row of die cavities, and said second plurality of die cavities are arranged in a spaced, straight line configuration forming a second row of said die cavities.
Claim 6
Dependent Claim
21 words
The apparatus defined in claim 4 wherein said first and second rows of die cavities in said die plate are parallel.
Claim 7
Dependent Claim
102 words
The apparatus defined in claim 4 wherein said first and second dispenser means comprise a plurality of spaced apertures in the bottom of said block disposed in a straight line configuration forming first and second rows of apertures adapted to be respectively aligned with said first and second rows of die cavities when said block is in said first transverse position; and said first and second pluralities of pickup means each comprise a row of bores disposed in a straight line configuration, each row being aligned with a row of die cavities to receive the compacted arTicles ejected from each die cavity.
Claim 8
Dependent Claim
33 words
The apparatus defined in claim 6 wherein each of said anvil surfaces is located along the bottom surface of said block between a row of dispenser apertures and a row of pickup bores.
