The production and use of the ring mill facilitate our production and life, and also promote the development of industry. But the ring rolling machine is the same as people. If you don't pay attention to maintenance, you will get "sick" from irregular inspection. Problems of one kind or another can occur, which may lead to the paralysis of the whole machine in serious cases. Therefore, we should master the knowledge about the maintenance of the ring mill to ensure its normal operation and prolong its service life.

We all know that the ring mill is a kind of rotary forming machine in forging equipment, mainly driven by motor and mechanical transmission. In the working process of the ring mill, the working part of the equipment and the processed parts rotate at the same time or one of them. Therefore, when using the ring rolling machine, we should add oil at each lubricating oil point as required before starting the machine. At ordinary times, we should always check whether the screws at each part are loose, whether there is oil leakage at the hydraulic part, and often clean the oil return filter. If there is screw looseness and oil leakage, we should deal with them in a timely manner.

　    Secondly, pay attention to whether the oil level of the hydraulic box is normal when using the ring rolling machine. The impurities shall be removed in time, and the pressure of the oil pump shall be checked to see if it meets the specified requirements. The rolling pressure shall be properly adjusted according to the temperature, size and material of the blank to ensure the quality and productivity of the forging. Check whether each lubricating oil path is unblocked. Inject oil to the working column, sliding block, coupling, and start production after the empty car runs normally. Also check whether the switches, solenoid valves and operating mechanisms of electrical appliances are normal. Regularly adjust the fitting clearance of the mold and tighten it. Before using the mold, preheat the mold. Carefully check whether the model, material, specification and mold of the product are consistent. Only when they are correct can they be put into production.

        When using the ring mill, pay attention to fully cooling the cooling parts. When rolling the blank, the ring mill shall not force cold rolling when the temperature is within 1000 ° - 1200 °, which may cause damage to the machine. When the ring mill is working, pay attention to the machine operation at any time, and stop the machine for repair in a timely manner when it is found. Moreover, the motor bearing shall be inspected once a year and filled with lubricating oil, and the sliding block bearing and core rod bearing shall be inspected once a half year. The pressure roll shall be cleaned every month, and the electric cabinet shall be checked every month to check whether the components are damaged and loose. In case of any abnormal condition, the pressure roll shall be replaced in time.
