It can be applied to the electrical control system of all kinds of YLL series hydraulic press: the PLC control technology can complete all kinds of process actions of the press, and the control is flexible and reliable. Profibus and DeviceNet Bus interfaces can be reserved, which provides the possibility of unified management and coordinated control for users. The human-machine interface adopts touch type or key control type display screen, which can display the working state of hydraulic press in real time and make the control process visible. The fine-tuning positioning mechanism adopts servo positioning, the accuracy can reach 0.01mm, the step distance is 0.05mm, which provides a guarantee for the development of high-precision mold.
