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.

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： The present invention relates to a servo press controller which can prevent the servo runaway caused by the malfunction of CPUs, the faults of a position sensor, or other troubles to thereby increase the safety of the servo press. For this purpose, first to third CPUs (21, 22, 23) each of which conducts a different control among the input of set data, the calculation of a servo position command, and the calculation of a servo speed command send and receive watch dog signals between itself and another CPU for monitoring each other's condition by checking whether the watch dog signals sent from the partner computer are normal or not, and, when there is an abnormality in any computer, stopping the servo press (1) for emergency.
