摘要： A control device, for a servo die cushion, capable of improving a response after overshoot generated by collision of a slide and a die cushion. The control device has a local maximum point judging part which judges a local maximum point based on the detected speed of the servomotor; a speed correction value calculating part which calculates a speed correction value for the servomotor based on the judgment result and the detected speed of the slide; a second force commanding part which generates a second force command value, the second force command value decreasing from an initial value to a first force command value, the initial value being equal to the force detected value when reaching generally the local maximum point. The force command value is switched from the first force command value to the second force command value, when the force detected value reaches the local maximum point.

摘要： A device for controlling a die cushion mechanism including a servo-motor as a drive source and producing a force adapted to be applied to a slide in a press machine. The device includes a section for commanding a force to be produced by the die cushion mechanism; a section for detecting a force produced by the die cushion mechanism and applied to the slide; a section for detecting a moving speed of the slide; and a section for executing a force control on the servo-motor. The force controlling section executes force controls in mutually different modes on the servo-motor, through mutually different control loops, one mode being provided for an initial stage defined from an instant when the die cushion mechanism starts producing the force to be applied to the slide until a predetermined subsequent instant, and another mode being provided for a succeeding stage defined after the predetermined subsequent instant, by using at least a slide-speed detected value detected by the slide-speed detecting section. The force controlling section includes a section for preparing a first speed-command value to be commanded to the servo-motor in the initial stage and a second speed-command value, different from the first speed-command value, to be commanded to the servo-motor in the succeeding stage.

摘要： A controller for a die cushion mechanism includes: a spring element that is displaced according to force between the die cushion mechanism and a slide; a force instructor that instructs force; a force detector that detects force; and a speed instruction generator that generates a speed instruction of the servo motor, based on a force instruction value instructed by the force instructor and a force detection value detected by the force detector. The speed instruction generator generates the speed instruction by multiplying a force gain by a force difference determined from a difference between the force instruction value and the force detection value. The speed instruction generator changes the force gain, based on a spring constant corresponding value of the spring element determined from a force indicator that works between the slide and the die cushion. With this arrangement, the die cushion mechanism can be controlled with high precision, even when a mechanical characteristic changes. A force indicator is a force instruction value or a force detection value. In place of the force indicator, a spring constant corresponding value can be determined according to displacement of the spring element or a position of the die cushion mechanism.
