    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.

    摘要： An actual plate thickness and actual material constants are measured during punching before bending. The measured information is reflected on the bending, so that the bending is performed efficiently and accurately. Punching is carried out for each blank developed based on a nominal plate thickness and nominal material constants in blanking before the bending of a work W. Then, an actual plate thickness distribution and an actual material constant distribution of the work W are calculated based on various data containing a ram stroke and a pressure detected in the punching.

    摘要： In the detector main body (29) of a bent angle detector, a pin shaft (35) having a first locking member (39) is constantly urged upward at substantially the center of a groove in a die (D) by a first spring (41). In the detector main body (29), a rotor support member (47) having second locking members (61, 63) is constantly upwardly urged by two second elastic bodies (49) having a smaller urging force than that of the first spring (41). In the upper region of the rotor support member (47), two rotors (51) are positioned on opposite sides in the direction of the groove width of the die (D) and journaled. A rotatable link member (43) engaging the first locking member (39) and second locking members (61, 63) stops the front end of the pin shaft (35) at a position below the upper surface of the die and positions the two rotors (51) at a position below the upper surface of the die.
