20090064839 | SERVO DRIVE SYSTEM AND CONTINUOUS WORKING SYSTEM OF PRESS MACHINE - A servo drive system of a press machine includes a ram, an operation shaft which vertically moves the ram, and a servo motor which operates as a power source of the ram and which generates ram pressure using a torque based on at least one speed-torque characteristic of the servo motor. The operation shaft is directly driven using the servo motor. The at least one speed-torque characteristic of the servo motor is set in a manner such that a motor torque of the servo motor at which a capacity of electric energy supplied by a servo amplifier is determined becomes the motor torque at which an optimal punching pattern of the ram is generated from a light load to a heavy load according to a type of workpiece to be worked by the press machine. | 03-12-2009 |
20090064838 | SERVO DRIVE SYSTEM AND CONTINUOUS WORKING SYSTEM OF PRESS MACHINE - A continuous working system of a press machine includes a ram, an operation shaft which vertically moves the ram, and a servo motor which operates as a power source of the ram and which generates ram pressure using a torque based on at least one speed-torque characteristic of a motor. The operation shaft is directly driven using the servo motor. The operation shaft 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 and an upper end position such that the ram vertically moves between these positions by the servo motor, thereby subjecting a work to a continuous press working. The upper end position is set to a position slightly below a medium height of the entire vertically possible stroke of the ram. The lower end position is set to a position slightly above a bottom dead center of the entire vertically possible stroke of the ram. | 03-12-2009 |

20090013840 | METHOD OF CUTTING OFF WORKPIECE USING BAND SAW MACHINE AS WELL AS BAND SAW MACHINE - In a cutting-off method, when a workpiece is to be cut off by use of an endless band saw blade suspended between a driving wheel and a driven wheel, the workpiece is cut off by imparting to the driving wheel a forced oscillation so that a phase of an oscillation of the driving wheel along its rotational direction is substantially inverted with respect to a phase of an oscillation of the driven wheel along its rotational direction. In addition, pulses can be applied to a driving motor for rotationally driving the driving wheel in order to cause the driving wheel to oscillate along its rotational direction. | 01-15-2009 |
20090007437 | METHOD OF CUTTING OFF WORKPIECE USING BAND SAW MACHINE AS WELL AS BAND SAW MACHINE - A method of cutting a workpiece using an endless band saw blade and a band saw machine are provided. The method includes suspending the endless band saw blade between a driving wheel and a driven wheel such that the workpiece may be cut by the endless band saw blade, applying at least a first pulse and a second pulse to a first motor rotating the driving wheel and a second motor rotating the driven wheel, respectively, wherein the pulses have phases opposite to each other, and cutting the workpiece. The band saw machine includes an endless band saw blade suspended between a driving wheel having a first motor and a driven wheel having a second motor. The band saw machine further includes a pulse applying module that applies at least a first pulse and a second pulse to the first motor and the second motor, respectively, wherein the pulses have phases opposite to each. | 01-08-2009 |
