Title:
METHOD FOR CHANGING DIE OF PRESS MACHINE AND PRESS MACHINE
Document Type and Number:
WIPO Patent Application WO/2008/013116
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a method for changing the die of a press machine by which
the time required for changing the die can be shortened sharply. [MEANS FOR SOLVING
PROBLEMS] In a press machine (servo drive press machine) where a slide can be
positioned at an arbitrary position by controlling a servo motor, the time required
for moving the slide is shortened by moving the slide within a range required for
changing the die. Furthermore, work for changing the die is quickened by performing
positioning control of the slide not through operation of a slide regulation
mechanism but through control of the servo motor and moving the slide to a height
suitable for changing the die, thereby omitting operation of the slide regulation
mechanism.
