Corrective Maintenance Of Cold Forging PressUpdate：2021-06-28 Hits：179
The correct use and maintenance of cold forging press, careful implementation of maintenance and compliance with operating procedures can extend the service life of machinery and equipment and ensure the prerequisites for stable production. Therefore, before using cold forging press, you should first master the machine's Structure, performance and operation process.
After the oil tank is filled with new oil or the oil is changed before the cold forging press starts the motor, before starting the oil pump for the first time, the pump must be filled with clean working oil from the oil outlet of the oil pump, otherwise, it is not allowed to start; for a long time; After stopping the machine (more than 2 hours), start the machine. In order to check the operating condition of the system, the oil pump should be left idling for 10 minutes without load, and there is no abnormality before operation. After the oil pump is started, wait until the oil pump start indicator light is on before operation can be carried out. ; The oil must be pure hydraulic oil, otherwise, it should be strictly filtered before it can be injected into the oil tank; Note: The oil volume must not be less than 3/4 of the height of the oil standard; the first replacement period of the oil in the oil tank must not exceed 6 month.
When the cold forging press is used, when the contact area between the mold and the lower plane of the upper beam is too small, a backing plate of appropriate thickness should be installed; the guide column of the movable table should be frequently lubricated with oil, and when working continuously, oil should be injected every 4 hours.
