Abstract: A press machine for forming a part comprises a moveable press ram, an actuator, a first motor, and a second motor. The moveable press ram is for holding a tool that forms the part. The actuator moves the moveable press ram. The actuator includes a first male-female thread mechanism for producing a first linear movement of the moveable press ram and a second male-female thread mechanism for producing a second linear movement of the movable press ram. The first linear movement is a high-force linear movement condition and the second linear movement is a high-speed linear movement condition. The first motor drives the first male-female thread mechanism to produce the first linear movement. The second motor drives the second male-female thread mechanism to produce the second linear movement.

Abstract: A press machine comprises a moveable press ram, an actuator, a first motor system, a second motor system, and a belt system. The moveable press ram holds a tool that forms a part. The actuator linearly moves the moveable press ram by use of a male-female thread mechanism. The actuator includes an actuator sprocket coupled to the male-female thread mechanism. The first motor system produces a high-force linear movement condition to the press ram, and includes a clutch coupled to a first motor and a first motor sprocket coupled to the clutch. The second motor system produces a high-speed linear movement condition to the press ram. The belt system couples the actuator sprocket, the first motor sprocket, and the second motor sprocket. The clutch allows the first motor to partially or fully disengage from rotational movement of the first sprocket when the belt is being driven by the second motor.

Abstract: A linear-actuated press machine comprises a press ram with a tool, a first linear actuator having a first actuator rod, a second line actuator having a second linear actuator rod, a high-speed motor coupled to the first linear actuator for providing a high-speed condition on the press ram, a first high-torque motor coupled to the first linear actuator, and a second high-torque motor coupled to the second linear actuator. The press machine (i) advances the tool toward the part by operation of the high-speed motor associated with the first linear actuator, (ii) forms the part with the tool by simultaneous operation of the first high-torque motor associated with the first linear actuator and the second high-torque motor associated with the second linear actuator, and (iii) retracts the tool from the part by operation of the high-speed motor associated with the first linear actuator.
