Document Type and Number:
WIPO Patent Application WO/2013/018469
Kind Code:
A1
Abstract:
The control device (40) of a press machine has a movement amount calculation unit (58) that, on the basis of the measured value for the die height prior to an adjustment applied when the height position of the slide is adjusted, and on the basis of the desired post-adjustment die height, the crank angle, the distance between the upper surface of a bolster and the crank center of an eccentric part, the crank radius of the eccentric part, and the distance from the lower surface of the slide to the point center, calculates the amount of slide movement, in association with the difference in die height before and after adjustment, when the slide is held at a waiting position that is displaced by a prescribed crank angle from the top dead center.
