In the maintenance of the piston rod of the hydraulic press, it is necessary to dismantle the relevant facilities in the structure, and at the same time, deal with the fracture, and then analyze whether the piston rod can be used after processing.

In the process of processing, it is required to analyze the interface of the joint state of the rod, evenly process the distributed M 30 threaded holes, make the rod according to the special processing requirements, and then use the high-strength socket head bolts to realize the connection between the rod and the bolt. At the same time, under necessary conditions, flange connection or other welding methods can be used in the fractured area of the piston rod of the hydraulic press to further strengthen the rod.

For the nut structure of the piston rod of the hydraulic press, it is necessary to leave a gap and adjust the running accuracy of the entire system. For the cylinder structure and refueling device, as well as the related slider system, use the operation mode of the facility. The system should completely remove the air inside the rod and the pipeline. After the installation work is completed, a load test is required. The maximum eccentricity must not be exceeded during the test run or in the subsequent operation.
