Fig. 3 is the flow chart of steps of method described in the present embodiment, comprises the following steps:
Step S10: the state of monitoring powder pressing machine powder filling.Powder pressing machine can circulate pressure in compacting production process
Powder process material.The state of press filling powder can be detected by more existing monitoring devices.Such as loadings is zero, dress
The amount of filling out is fully loaded by different feedback signal back.
Step S20: it is same that reception powder pressing machine has loaded the signal of powder, the first hydraulic actuator and the second hydraulic actuator
Time to equidirectional move.In this step, detect that powder pressing machine has loaded by existing monitoring device and need compacting
After powder, send a signal to control system.Control system order the first hydraulic actuator and the second hydraulic actuator are simultaneously to identical
Direction moves downward.
Step S30: ceaselessly detect the first hydraulic actuator and the physical location of the second hydraulic actuator.
Step S40: when the first hydraulic actuator moves to position to be detected, it is judged that whether the second hydraulic actuator arrives at it
Target location；When the second hydraulic actuator arrives its target location, the first hydraulic actuator keeps former speed to continue to move to it
Target location；When the second hydraulic actuator does not also arrive its target location, then perform step S50.Rising at the first hydraulic actuator
A position to be detected is set between beginning position and target location.When the first hydraulic actuator arrives position to be detected, detection dress
Put and detection signal is sent to control system.Now, the movement position of the second hydraulic actuator is detected by detector.By
The contrast of the physical location of two hydraulic actuators and its target location is it is known that both sizes.
Step S50: control the safe speed that the first hydraulic actuator is decelerated to preset, and continue to move to its target location；
Meanwhile, the second hydraulic actuator keeps former speed to continue motion, and controller mark delay warning mark.
Step S60: when the first hydraulic actuator moves to its target location, it is judged that whether the second hydraulic actuator arrives at its mesh
Cursor position, if so, controls powder pressing machine and performs powder pressing；If it is not, perform step S70.At the first hydraulic actuator
After arriving its target location, the second hydraulic actuator does not also arrive its target location and then illustrates that the second hydraulic actuator is likely by card
Live or abnormal state.
Step S70: strengthen the driving power of the control valve of the second hydraulic actuator.In order to avoid operator mistakenly by second
The actuator speed command when S20 arranges too low or parameter correct, therefore increases power.
