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 connected to the drive shaft; and a control part configured to control respective operations of the clutch and the servomotor, wherein the control part is configured to perform such control as to cause the drive shaft to rotate with the driving of the flywheel in at least one of a rising process, in which the slide is caused to rise, to cause the slide to rise and a lowering process, in which the slide is caused to lower, to cause the slide to lower.
Claims8
A forging press, comprising:
- 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 connected to the drive shaft;
- and
- a control part configured to control respective operations of the clutch and the servomotor,
- wherein the control part is configured to perform such control as to cause the drive shaft to rotate with driving of the flywheel in at least one of a rising process, in which the slide is caused to rise, to cause the slide to rise and a lowering process, in which the slide is caused to lower, to cause the slide to lower.
A method of controlling a forging press, the forging press including 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, and a servomotor connected to the drive shaft, the method comprising:
- causing the drive shaft to rotate with driving of the flywheel in at least one of a rising process, in which the slide is caused to rise, to cause the slide to rise and a lowering process, in which the slide is caused to lower, to cause the slide to lower.
