In daily life, no matter how good the equipment is, if there is no good overhaul and maintenance awareness, it will affect the efficiency of the machine over time. Everyone knows that the nature of the metal, the shearing temperature and other factors will affect the shearing quality of the shearing machine. To a large extent, it is the lack of maintenance and maintenance awareness that will cause some unnecessary troubles. Therefore, our company has summarized the problem of shearing machine failure, so as to ensure that the machine can be solved and maintained well when the machine fails. There are mainly the following three reasons in daily life:
In terms of oil cylinder: After the machine is powered on, the oil cylinder cannot generate pressure. At this time, it is because the liquid oil contains impurities during the oil suction process for a long time, which causes the overflow valve to be blocked. After the oil cylinder is started, the adjustment handle may become loose due to the loosening of the valve core and spring, and it is not easy to operate. During the operation, if the oil cylinder is found to be displaced, the operation must be stopped at this time, and the air in the system must be exhausted. , Reduce the air pressure inside the system, and make the system and the oil cylinder relatively vacuum state.
Oil pump: also after the machine is started, if the oil pump does not work, check the electromagnet or replace the electromagnet. It is likely that the electromagnet loop fails due to long-term use and cannot generate magnetic force; or dust enters When the steering valve spool is reached, the spool is stuck, causing the oil pump to fail to work. This failure can be resolved by cleaning or replacing the steering valve. During the operation of the oil pump, sometimes the oil cannot be sucked due to the loosening of the adjusting handle. When checking the oil cylinder, be sure to check the valve core and spring. There is also a common phenomenon. When the oil pump is running, there will be a lot of noise or abnormal noise. At this time, it is necessary to check the problem of the oil circuit, because the oil leakage of the oil suction pipe will cause the oil pump to supply insufficient oil, and the oil pump will appear. The harsh noise.
In terms of cutting edge: Too high or too low cutting edge will result in non-standard distance between the blade gap. During the cutting process, the cut material will be irregular and of poor quality. At the same time, if the height of the cutting blade is not adjusted properly, thin materials are easy to cut, and thicker materials cannot be cut. Therefore, adjusting the gap of the cutting blade is also a crucial factor in the cutting quality.
The above 3 points are that you have encountered more in the process of using. Only by mastering these common faults, we will be more handy when using the shearing machine.
