Abstract
Disclosed is a die press with a base, at least two cam members spaced from the base, an upper platen located between the base and the two cam members to define a space for a die, the upper platen being generally parallel to the base, the upper platen also being attached to the two cam members so that when the two cam members are actuated, the upper platen is moveable relative to the base, and a linkage connecting the two cam members so that the two cam members move in unison relative to each other when actuated.
Claims34
A die press, comprising:
- a base or lower platen;
- an upper platen spaced from the base or the lower platen;
- at least two means for applying pressure upon the upper platen to move the upper platen toward the base or lower platen;
- and
- means for moving in unison the at least two means for applying pressure on the upper platen.
A die press having a base, at least two opposing supports extending from the base, with two cam members that are supported by the opposing supports, the die press further comprising:
- an upper platen positioned between the two cam members and the base, the upper platen being spaced from and being movable relative to the base;
- and
- a linkage connecting the two cam members so that the two cam members are adapted to move in unison with respect to each other.
A die press, comprising:
- a base;
- at least two cam members spaced from the base;
- an upper platen located between the base and the two cam members to define a space for a die, the upper platen being generally parrallel to the base;
- the upper platen being attached to the two cam members so that when the two cam members are actuated, the upper platen is movable relative to the base;
- and
- a linkage connecting the two cam members so that the two cam members move in unison relative to each other when actuated.
A die press, comprising:
- a base;
- an upper platen opposite of the base;
- means for moving the upper platen toward the base by rotating at least two cam members;
- and
- means for rotating the cam members at the same time.
A method of actuating a die press, comprising:
- a step for rotating at least two cam members generally simultaneously;
- and
- a step for applying force to a platen to move the platen toward a base of the die press.
A die press, comprising:
- a base;
- at least two cam members spaced from the base;
- an upper platen located between the base and the two cam members to define a space for a die, the upper platen being generally parallel to the base;
- the upper platen being attached to the two cam members so that when the two cam members are actuated, the upper platen is movable relative to the base;
- each cam member having located on one end a gear;
- and
- a gear rack that is engaged with each of the cam member gears so that the two cam members move in unison relative to each other when actuated.
