Abstract
A press machine includes at least one actuator and at least one linkage to open and close a ram. Another aspect employs a sheet metal-working punch mounted to the ram. A fluid-powered piston drives a carriage coupled to a linkage in another aspect of the present machine. In still another aspect, at least a majority of an actuator is located externally to an outside surface of a stationary structure within which a ram is located. Yet a further aspect both opens and closes a ram with a unidirection movement of an actuator.
Claims38
A machine comprising:
- a stationary structure including substantially vertical outside surfaces;
- at least one actuator coupled to the structure with at least a majority of the actuator being located external to the outside surfaces of the structure;
- a slide being linearly movable in a substantially horizontal direction, between the outside surfaces of the structure;
- a sheet metal-working press coupled to and movable relative to the stationary structure;
- and
- a linkage having only two pivots, a first of the pivots being directly attached to the slide and a second of the pivots being directly attached to the press;
- energization of the actuator operably moving the slide in the substantially horizontal direction which operably rotates the linkage which operably moves the press in a substantially vertical direction.

A machine comprising:
- a metal-working press;
- multiple fluid-powered pistons coaxially aligned with each other;
- at least one piston rod extending between the pistons;
- at least one slide movable between the pistons in response to movement of the piston rod;
- multiple parallel linkages coupling the at least one slide to the press;
- linear movement of the pistons along solely a first direction operably causing the slide to linearly move in the first direction, which operably rotates the linkages, which both linearly advances and retracts the press along an axis substantially perpendicular to the first direction;
- and
- reverse linear movement of the pistons along solely a second direction opposite to the first direction operably causes the slide to linearly move in the second opposite direction, which operably reverse rotates the linkages, which both linearly advances and retracts the press along the axis.

A machine comprising:
- a metal-working press;
- an actuator operably driving at least one carriage along a first linear axis;
- and
- multiple linkages each having only two pivots, a first of the pivots of each linkage being attached to the at least one carriage, and a second of the pivots of each linkage being attached to the press;
- when operating, unidirectional movement of the at least one carriage along the first linear axis rotates the linkages which causes both advancing and retracting of the press along a second linear axis substantially perpendicular to the first linear axis.
2 more elements
A machine comprising:
- an upstanding tool body;
- a base coupled to the tool body;
- a metal-working die attached to the base;
- a tool support coupled to the tool body opposite the base;
- an electric motor attached to the tool support;
- a jack-screw rotatable by the electric motor;
- a carriage enmeshed with the jack-screw;
- a linkage being rotatable in response to linear movement of the carriage;
- a ram being linearly advanceable due to rotation of the linkage, a linear advancing direction of the ram being substantially perpendicular to an elongated axis of the jack-screw;
- and
- a metal-working punch coupled to the ram and being aligned with the die.

- (i) piercing, and (ii) clinching, in response to step (d);
- and
- (f) retracting the member in a second direction opposite the first direction.
