This kind of structure adopts mechanical structure and hydraulic drive, which combines the advantages of mechanical and hydraulic pressure machines. It not only has the characteristics of good pressure control of hydraulic machines, but also has the advantages of fast speed of mechanical presses. At the same time, the requirements for the control system are also different from The traditional hydraulic system control has different requirements. At present, the automatic feeding control process of the traditional high-speed connecting rod multi-station press is mainly controlled by humans, that is, the staff will manually start the next one after the current process is completed according to the process. process, so the entire control process is the sum of multiple intermittent processes, so a lot of time will be wasted and work efficiency will be reduced
