Abstract
A motion generation device generates motion of a slide in a press device configured to perform press molding by driving the slide up and down using a servo motor as a drive source. The motion generation device includes an acquisition component and a second motion generator. The acquisition component acquires data related to a change in a load exerted on the slide in press molding using a first motion. The second motion generator generates a second motion from the first motion based on the change in the load.
Claims11
A motion generation device for generating motion of a slide in a press device configured to perform press molding by driving the slide up and down using a servo motor as a drive source, the motion generation device comprising:
- an acquisition component configured to acquire data related to a change in a load exerted on the slide in press molding using a first motion;
- and
- a second motion generator configured to generate a second motion from the first motion based on the change in the load.
A press device for press molding a material using an upper die and a lower die, the press device comprising:
- a slide having a lower face attachable to the upper die;
- a servo motor configured to be used as a drive source for the slide;
- a servo controller configured to control the servo motor based on a specific motion to raise and lower the slide;
- a load sensor configured to detect load exerted on the slide in press molding;
- and
- a second motion generator configured to generate a second motion from the first motion based on a change in the load exerted on the slide in press molding using the first motion.
A motion generation method for generating motion of a slide in a press device configured to perform press molding by driving the slide up and down using a servo motor as a drive source, the motion generating method comprising:
- generating a second motion from a first motion based on a change in load exerted on the slide in press molding using the first motion.
A motion generation program for generating motion of a slide in a press device configured to perform press molding by driving the slide up and down using a servo motor as a drive source, the motion generating program comprising:
- executing a motion generation method with a computer in which a second motion is generated from a first motion based on a change in load exerted on the slide in press molding using the first motion.
