摘要： A press machine includes a controller including a top-dead-center detector adapted to: rotate a main shaft in a predetermined direction selected from a normal rotation direction and a reverse rotation direction to place a slide at a first position displaced relative to a top dead center of the slide by a predetermined height; while outputting and counting pulses from an angle detector, rotate the main shaft in a direction opposite to the predetermined direction to move the slide to a second position located at the same height as the first position beyond the top dead center; and rotate the main shaft from the second position in the predetermined direction by an amount corresponding to a half of the counted pulses to detect the top dead center.

摘要： A press machine includes a controller including a displacement calculator being adapted to calculate a slide displacement with a slide being kept at a waiting position displaced from a top dead center by an amount corresponding to a predetermined crank angle based on a measured value of a pre-adjustment die height provided for a height adjustment of the slide, a desired value of a post-adjustment die height, the crank angle, a distance between an upper surface of a bolster and a crank center of an eccentric portion, a crank radius of the eccentric portion, and a distance between a lower surface of the slide and a point center, thereby associating the slide displacement with a difference between the pre-adjustment die height and the post-adjustment die height.
