In the motion process of the first hydraulic actuator and the second hydraulic actuator, the second monitoring modular measures both positions in real time, and both positional informations are sent to the second control module.
When the first hydraulic actuator moves to position to be detected, the second control module judges whether the second hydraulic actuator arrives at its target location.If arrived, then the first hydraulic actuator keeps former speed to move to its target location, controls powder pressing machine and performs powder pressing.If do not arrived, then notify the 3rd control module.
3rd control module controls the first hydraulic actuator and is decelerated to default safe speed v1, and continues to move to its target location.Meanwhile, the second hydraulic actuator keeps former speed to continue motion, the mark and controller mark delay is reported to the police.Deceleration can provide the more time for the second hydraulic actuator work, improves the reliability of system.
When the first hydraulic actuator moves to its target location with safe speed v1, the 4th control module judges whether the second hydraulic actuator arrives at its target location.If so, then control powder pressing machine and perform powder pressing; If not, the 5th control module is notified.
When 5th control module receives the signal of the 4th control module, it strengthens the driving power of the control valve of the second hydraulic actuator.
After 5th control module increases the driving power of the control valve of the second hydraulic actuator, after limiting time, the 6th control module judges whether the second hydraulic actuator arrives its target location.If arrival target location, the second hydraulic actuator motion is normal, then can control powder pressing machine and perform powder pressing.If not, then illustrating that the second hydraulic actuator may be blocked by foreign matter and cannot decline, is proterctive equipment, and powder pressing machine must be shut down at once and report to the police, and again could enter automatic cycle after artificial reset is reported to the police and eliminated fault.
Native system also comprises the 7th control module.After control powder pressing machine performs powder pressing, the 7th control module checks whether controller has delayed alarm to identify.When controller mark delay reports to the police mark, then powder pressing machine is shut down and is reported to the police, and allows attendant investigate fault and reset could enter automatic cycle again after eliminating fault.When controller does not mark delayed alarm mark, illustrate that the first hydraulic actuator keeps former speed to move to its target location, powder pressing machine performs powder pressing, then can carry out cyclic pressing adobe.
