Title:
CONTROL DEVICE AND CONTROL METHOD FOR SERVO-PRESS
Document Type and Number:
WIPO Patent Application WO/2006/030649
Kind Code:
A1
Abstract:
A control device and a control method for a servo-press capable of selectively performing high-production working and high-accuracy working by one pressing machine. The servo-press (1) is so formed that an eccentric rotary mechanism (20) is driven by a servo-motor (21), and the rotating power of the eccentric rotary mechanism (20) is transmitted to a slide (3) through a toggle link mechanism (15) to vertically drive the slide (3). The rotation of the servo-motor (21) is controlled by a motor speed instruction (rm) calculated based on a position gain (G (Ѳ)) pre-set according to the position deviation (&epsiv p) of the slide (3) and the speed ratio of the slide (3).
