摘要： If an instruction to move a ram (5U) is issued, a ram instructed speed is instructed to be suppressed to a certain warming-up speed not higher than a target speed until a release speed determination section (75) determines that a moving speed of the ram (5U) calculated by a ram moving speed calculation section (51) reaches a predetermined warming-up release speed; if the release speed determination section determines that the moving speed of the ram (5U) reaches the predetermined warming-up release speed, the warming-up speed is released to accelerate the ram (5U) to the target speed.

摘要： A rod pressure holding instruction section controls a servo motor to rotate a two-way pump in a counter direction, and to supply hydraulic oil, with pressure which does not exceed pressure from a weight of a ram, to a two-way pump-side piping, increasing pressure. A difference between pressure in a rod-side cylinder chamber-side piping of a speed switching valve and pressure in a two-way pump-side piping of the speed switching valve is decreased, thereby decreasing an impact generated when switching the speed switching valve and stopping the ram at a predetermined position.

摘要： A controller for a press brake controls a servomotor to reverse the rotation of a bidirectional piston pump so as to reverse the vertical movement of a hydraulic cylinder and a ram. A command generator maintains a constant speed for a predetermined warmup time or distance after the ram movement is reversed, and afterwards changes the ram speed to a predetermined speed. A ram position, set according to a moving speed pattern, is compared to the actual position of the ram to conform the ram to the moving speed pattern. The moving speed may be limited based on at least one of a pressure and a detected by a pressure sensor.
