|
Taking S7-300PLC as the core to build the experimental platform for the hydraulic press's overflow compensation synchronous balancing control system,The active unbalanced loading crossbeam of hydraulic press was deflected through installing the mold at the bias position on working platform.To start the synchronous system when the opposite deviation is over a setted value.The overflow compensation synchronous control system was able to achieve the optimal balance of the corrective effect through adjusting the control parameters of the PID module.The experimental curves of the opposite deviation of the active crossbeam,and the pressure and the current capacity of the correcting cylinder's high and low cavity were contrasted and analyzed.The experimental results verify' the high accuracy in synchronism of the experiment hydraulic press.Its synchronized balancing system precision can achieve 0.030mm·m-1 and the control time is smaller than 2.9s.
