| Abstract: | Omnipotent hydraulic press with four poles has been PLC renovated to making the basic action come true.The overflow valve to control the constant blank holder force is changed to the proportion overflow valve.With the technology of PLC and the electricity-liquid control,the 2-PID closed-loop control is adopted to achieving the variable blank holder force control.By the mode,the technical need of variable blank holder force can be satisfied and the control level of the hydraulic press can be improved. |
