The commissioning and use of the ring rolling machine has facilitated our production and life, and also promoted the development of industry. However, the ring rolling machine is also the same as people, if you don't pay attention to maintenance, you will be "sick" if you don't check it regularly. Problems of one kind or another will occur, and in severe cases, the entire machine may be paralyzed. Therefore, we must master the knowledge of maintaining the ring rolling machine to ensure the normal operation of the ring rolling machine and prolong the service life of the ring rolling machine.
We all know that the ring rolling machine equipment is a kind of rotary forming machinery in the forging equipment, which mainly adopts motor drive and mechanical transmission. In the working process of the ring rolling machine, the working part of the equipment and the processed parts are both at the same time or with one of them to do rotational motion. Therefore, when we use the ring rolling machine, we should add oil to each lubricating oil point according to the regulations before starting the machine, and usually check whether the screws of each part are loose, and also check whether there is oil leakage in some parts of the hydraulic pressure, and often clean the oil return oil filter, if there is loose screws and oil leakage, we must deal with it in time.
Secondly, when using the ring rolling machine, it is necessary to pay attention to whether the oil level of the hydraulic tank is normal. And to remove impurities in time, check whether the pressure of the oil pump meets the specified requirements. Adjust the rolling force appropriately according to the temperature, size and material of the blank to ensure the quality and productivity of the forging. Check whether the lubricating oil circuit is unblocked, lubricate the working column, slider, coupling, and lubricate, and run the empty car first, and wait for the normal operation of each part before starting production. It is also necessary to check whether the switches of electrical appliances, various solenoid valves and operating mechanisms are normal. Adjust the mold with the gap and tighten it from time to time, preheat the mold before use, carefully check whether the model, material, specification and mold of the product are consistent, and the production can only be carried out after accuracy.
When using the ring rolling machine, it is necessary to pay attention to the full cooling of the cooling part, and the ring rolling machine shall not be forced to cold roll when the temperature is in the range of 1000 °-1200 °, which will lead to damage to the machine. Moreover, the motor bearing should be inspected and lubricated once a year, and the slider bearing and mandrel bearing should be inspected every six months. And to clean and replace the lubricating oil, the pressure roller should be cleaned every month, and the electric control box should be checked once a month to check whether the components are damaged and whether there is looseness, and replace them in time when abnormal conditions are found.
