Abstract
The press device is a press device configured to press a workpiece, and includes a slide, a bolster, a servomotor, and a control section. The slide is movable. The bolster is placed to face the slide. The servomotor drives the slide. The control section is configured to be able to execute selectively either the productivity priority mode of setting a limit value slower than the maximum press speed of the press device to the press speed when performing a pendulum motion or a reverse motion, or the moldability priority mode of setting a stop time to the servomotor without setting the limit value.
Claims13
A press device for pressing a workpiece, comprising:
- a slide configured to be movable;
- a bolster placed facing the slide;
- a servomotor configured to drive the slide;
- and
- a control device including a processor and a storage, the control device being configured to execute selectively between
- a first mode of setting a limit value of a press speed when performing a Pendulum motion or a reverse motion, the limit value being slower than a maximum press speed of the press device, and
- a second mode of setting a first stop time to the servomotor without setting the limit value.
A press system comprising:
- a press device main body including a slide configured to be movable, a bolster placed facing the slide, and a servomotor configured to drive the slide;
- and
- a control device configured to selectively cause the press device main body to execute selectively between
- a first mode of setting a limit value of a press speed when performing a pendulum motion or a reverse motion, the limit value being slower than a maximum press speed of the press device main body, and
- a second mode of setting a first stop time to the servomotor without setting the limit value.
