Abstract
Abstract A multiple cavity press system for providing at a remote station both part collection and tool setup with provision for incremental, fine adjustment of ram fill and ram press stroke. For each press, the required incremental adjustment may be controlled from the remote station so that the appropriate size and weight corrections may be made immediately upon inspection of the collected parts. An operating means including a pneumatically actuated slide is used to provide for the incremental adjustment of ram travel in either direction.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
106 words
A system for operating a plurality of ram operated, powder compacting presses in a remote press installation comprising: a remote control station having a collecting means for separately accumulating finished parts from said presses for inspection; a separate means for adjusting the extent of movement of the ram associated with each of said presses through its successive fill and press operations; and an operating means operably connected to said adjusting means for incrementally adjusting the ram movement for at least one of the aforesaid operations, said operating means located in said remote control station to facilitate finished part inspection and corrective ram setup at said station.
Claim 2
Independent Claim
106 words
A system for operating a plurality of ram operated, powder compacting presses in a remote press installation comprising: a remote control station having a collecting means for separately accumulating finished parts from said presses for inspection; a separate means for adjusting the extent of movement of the ram associated with each of said presses through its successive fill and press operations; and an operating means operably connected to said adjusting means for incrementally adjusting the ram movement for at least one of the aforesaid operations, said operating means located in said remote control station to facilitate finished part inspection and corrective ram setup at said station.
Claim 3
Dependent Claim
31 words
The combination as set forth in claim 1 wherein said collecting means includes a conduit and a removing means operatively connecteD to a die cavity of each of said presses, respectively.
Claim 4
Dependent Claim
30 words
The combination as set forth in claim 2 wherein said removing means comprises an aspirator and said finished parts are moved to said remote control station by pressurized air flow.
Claim 5
Dependent Claim
47 words
The combination as set forth in claim 1 wherein said separate ram adjusting means comprises a toothed wheel operably connected to each of said rams, and said operating means comprises a stepping means engageable with said wheel and movable in either direction for providing said incremental adjustment.
Claim 6
Dependent Claim
47 words
The combination as set forth in claim 4 wherein said stepping means comprises a pneumatically operated slide having a pair of projections engageable with the teeth of said wheel, and wherein a valve operating means is operably connected to said slide for controlling its direction of movement.
Claim 7
Dependent Claim
48 words
The combination as set forth in claim 1 wherein each of said press rams is operated through its respective press operations by a cam drive means, and wherein said means for adjusting comprises a yoke and a gear means for controlling the operation of said drive cam means.
Claim 8
Dependent Claim
102 words
Apparatus for providing a remotely controlled adjustment for a powder compacting press having a ram and a punch mounted on said ram and movable relative to a cavity of a die plate for successive fill and press operations comprising: a means operatively connected to said ram for incrementally adjusting ram movement for at least one of the aforesaid operations, said adjusting means comprising a rotatable adjusting means having a plurality of teeth about its periphery; a stepping means for said rotatable means comprising a differentially movable slide engageable with said teeth; and a means for selectively actuating said slide in either direction.
Claim 9
Dependent Claim
102 words
Apparatus for providing a remotely controlled adjustment for a powder compacting press having a ram and a punch mounted on said ram and movable relative to a cavity of a die plate for successive fill and press operations comprising: a means operatively connected to said ram for incrementally adjusting ram movement for at least one of the aforesaid operations, said adjusting means comprising a rotatable adjusting means having a plurality of teeth about its periphery; a stepping means for said rotatable means comprising a differentially movable slide engageable with said teeth; and a means for selectively actuating said slide in either direction.
Claim 10
Dependent Claim
56 words
The combination as set forth in claim 7 wherein a cylinder having a piston is operatively connected to said slide for moving it, and a valve means is operably connected to provide pressure to said piston including a pair of control valves, said valve means connected between a pressure source and both ends of said cylinder.
Claim 11
Dependent Claim
37 words
The combination as set forth in claim 7 wherein said adjusting means is operable to control the lowermost position of said ram during cavity fill operation thereby to adjust the weight of parts produced by said press.
Claim 12
Dependent Claim
42 words
The combination as set forth in claim 7 wherein a cam driven lever is operably connected to said ram for driving it through its press stroke, and said adjusting means is operable to preset the uppermost limit of movement of said ram.
Claim 13
Dependent Claim
27 words
The combination as set forth in claim 10 wherein a variable extending cam driving said lever is selectively movable by said adjusting means to control its operation.
Claim 14
Dependent Claim
40 words
The combination as set forth in claim 8 wherein said piston is spring biased to normally inactive central position in said cylinder, and said operating valve is manually movable to connect said pressure source to one end of said cylinder.
