    摘要： A continuous working system of a press machine uses a servo motor (30a,30b) as a power source of a ram. An operation shaft (20) which vertically moves the ram is directly driven by using a servo motor (30a,30b) which can generate necessary ram pressure by using a torque based on speed-torque characteristics of a motor (30a,30b). The operation shaft (20) is continuously reciprocated and turned through an angle range corresponding to a distance between a predetermined lower end position required for press working by the ram (22) and a position where the ram (22) is returned from the lower end position and a lower end of the ram (22) is separated from a tool upper surface such that the ram (22) vertically moves between these positions by the servo motor (30a,30b), thereby subjecting a work to a continuous press working.

    摘要： A servo drive system of a press machine uses servo motors as driving sources of a ram. The servo motors are opposed to each other at opposite ends of an operation shaft which vertically moves a ram, and the servo motors composite and use torques based on the same speed-torque characteristics. Necessary ram pressure can be generated without utilizing inertia of a mechanism, and the system employs a pair of servo motors in which if a load is received from a work during a lowering operation of the ram, motor speed is reduced according to the load, thereby reducing the lowering speed of the ram. The pair of servo motors are integrally operated, thereby directly driving the operation shaft.
