Abstract
A press machine for forming a part comprises a planetary gear system, a first motor, a second motor, a linear actuator, and a press ram that holds a tool. The planetary gear system includes a ring gear, a sun gear, and a plurality of planet gears between the sun gear and the ring gear. The planetary gear system has an output shaft that is coupled to the linear actuator. The first motor is coupled to the planetary gear system for producing a high-speed condition on the linear actuator and the press ram. A second motor is coupled to the planetary gear system for producing a high-torque condition on the linear actuator and a corresponding high-force condition the press ram. The press ram forms the part with the tool during the high-force condition.
