FORGING PRESS AND METHOD OF CONTROLLING SAME
Abstract:
A forging press includes a slide configured to have a die attached thereto; a drive shaft configured to cause the slide to rise and lower by rotating; a flywheel connected to the drive shaft via a clutch; a servomotor and an electric generator each connected to the drive shaft; an electricity storage part configured to store the electricity generated by the electric generator and to feed the servomotor with electric power; and a control part configured to control the operations of the clutch, the servomotor, and the electric generator. The control part performs such control as to cause the electric generator to generate the electricity with the rotation of the drive shaft and to store the generated electricity in the electricity storage part during the rotation of the drive shaft with the driving of the flywheel and/or during the rotation of the drive shaft with an inertial force.
