Abstract
Abstract A press having both upper and lower punch operations with controlled action stroke for both upper and lower punches slidable in opposed directions with relationship to a multiple cavity die plate. The upper ram and punches are operated in the downward stroke by a toggle and rocker arm mechanism which incorporates a readily adjustable eccentric means for controlling the length of upper ram stroke. The mechanism further includes a combination of first and second class levers which are cam driven in a cyclical press operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
223 words
A powder compacting press comprising: a frame; means on said frame for supporting a die plate having at least one cavity therein; an upper ram slidably disposed in said frame above said die plate; a lower ram slidably disposed in said frame below said die plate; a rocker arm having an end pivotably mounted on said frame above said upper arm; a link element having an end pivotably affixed to said ram and another end pivotably connected to the other end of said rocker arm; a laterally extending arm integral with said rocker arm; a lever pivotally mounted on said frame and having an end engaging the end of said arm; a rotatable cam engageable with the other end of said lever; and biasing means for continuously engaging the ends of said lever respectively with the end of said arm and with said cam; whereby rotation of said cam causes pivoting of said lever for laterally displacing said arm from a position wherein said rocker arm and said link are pivotally angularly disposed to a position wherein they are substantially aligned for reciprocating said upper ram relative to said die plate; means for reciprocating said lower ram in timed relationships with said upper ram; and powder compacting members actuated by said upper and lower rams for compacting powder material disposed in said cavity.
Claim 2
Dependent Claim
223 words
A powder compacting press comprising: a frame; means on said frame for supporting a die plate having at least one cavity therein; an upper ram slidably disposed in said frame above said die plate; a lower ram slidably disposed in said frame below said die plate; a rocker arm having an end pivotably mounted on said frame above said upper arm; a link element having an end pivotably affixed to said ram and another end pivotably connected to the other end of said rocker arm; a laterally extending arm integral with said rocker arm; a lever pivotally mounted on said frame and having an end engaging the end of said arm; a rotatable cam engageable with the other end of said lever; and biasing means for continuously engaging the ends of said lever respectively with the end of said arm and with said cam; whereby rotation of said cam causes pivoting of said lever for laterally displacing said arm from a position wherein said rocker arm and said link are pivotally angularly disposed to a position wherein they are substantially aligned for reciprocating said upper ram relative to said die plate; means for reciprocating said lower ram in timed relationships with said upper ram; and powder compacting members actuated by said upper and lower rams for compacting powder material disposed in said cavity.
Claim 3
Dependent Claim
28 words
The press of claim 1 wherein said biasing means comprises a single acting fluid cylinder having a piston rod with the end thereof pivotally attached to said arm.
Claim 4
Dependent Claim
34 words
The press of claim 1 wherein the powder compacting member actuated by the lower ram is a punch member engaged in said cavity from below said die plate and reciprocable by said lower ram.
Claim 5
Dependent Claim
30 words
The press of claim 3 wherein the powder compacting member actuated by the upper ram is an anvil positionable over said die cavity and clamped down by said upper ram.
Claim 6
Dependent Claim
28 words
The press of claim 3 wherein the powder compacting member actuated by the upper ram is a punch member mounted on said ram and engageable in said cavity.
Claim 7
Dependent Claim
44 words
The press of claim 3 wherein the powder compacting member actuated by the upper ram comprises an anvil portion and a punch portion, said anvil portion being clamped down over said cavity by said ram and said punch portion being engageable into said cavity.
Claim 8
Dependent Claim
20 words
The press of claim 3 further comprising means for adjusting the position of said upper ram above said die plate.
Claim 9
Dependent Claim
26 words
The press of claim 7 wherein said adjusting means comprises an eccentric cylindrical member for pivotally mounting the end of said rocker arm on said frame.
Claim 10
Dependent Claim
47 words
The press of claim 8 further comprising a gear mounted on one end of said eccentric member and a worm meshing with said gear such that rotation of said worm controllably rotates said eccentric member for adjusting the position of said upper ram above said die plate.
