With the development of our country’s manufacturing industry, the development of hydraulic shearing machines has increasingly become the mainstay of the machinery manufacturing industry, but there are also some problems in actual operation, especially some small problems that often need to repair when the machine is in operation for a long time. Let us take a look at how to deal with the common situations of hydraulic shearing machines and maintenance methods.<\/p>\n\n\n\n

After cutting, the m\u00e1y c\u1eaft c\u1ecf<\/a> should be able to ensure the straightness and parallelism requirements of the cutting surface of the cut sheet and minimize the distortion of the sheet to obtain high-quality workpieces. Its upper blade is fixed on the knife holder, and the lower blade is fixed on the workbench. The workbench has installed a material holding ball so that it will not scratch the sheet material when sliding on it. The back gauge is used for positioning the plate, and the position is adjusted by the motor. The pressing cylinder can compress the sheet to prevent the sheet from moving during cutting. The guardrail is a safety device to prevent work-related accidents. The return journey generally relies on nitrogen, which is fast and has little impact.<\/p>\n\n\n\n

4 Preliminary Troubleshooting of Hydraulic Shearing Machine<\/span><\/strong><\/h3>\n\n\n\n

1. Ask the equipment operator to understand the operating conditions of the hydraulic system of the shearing machine. It includes: whether its hydraulic system is working normally; whether the hydraulic pump is abnormal; the time and result of checking the cleanliness of the hydraulic oil; the cleaning and replacement of the filter element; whether the hydraulic components have adjusted before the failure; whether the sealing components have replaced. What abnormal phenomena have occurred in the hydraulic system of the machine before and after the failure; what failures have occurred in the system in the past, and how to eliminate them, etc., everyone needs to understand.<\/p>\n\n\n\n

2. Look at the actual working conditions of its hydraulic system, and observe whether there are problems with system pressure, speed, oil, leakage, vibration, etc.<\/p>\n\n\n\n

3. Listen to the sound of its hydraulic system, such as impact sound; pump noise, and abnormal sound; judge whether the hydraulic system is working normally.<\/p>\n\n\n\n

4. Touch the temperature rise, vibration, crawling, and tightness of the joints to determine whether the working condition of the moving parts of the hydraulic system is normal.<\/p>\n\n\n\n

5 Points to Note During Troubleshooting<\/h3>\n\n\n\n

1. When finding the troubleshooting point of the hydraulic shearing machine and repairing them, be careful not to find the troubleshooting point as the endpoint, and the shearing machines’ operators should carry out further analysis and identification of the root cause of the troubleshooting.<\/p>\n\n\n\n

2. After the hydraulic shearing machine finds out the troubleshooting point, it is necessary to take corresponding correct repair methods for different troubleshooting conditions and parts.<\/p>\n\n\n\n

3. In the repair work of the hydraulic shearing machine, under normal circumstances, the operator should restore it as much as possible.<\/p>\n\n\n\n

4. After the troubleshooting is repaired, when the hydraulic shearing machine needs to be tested, they should cooperate with the operation controller to avoid new troubleshooting.<\/p>\n\n\n\n

5. After each troubleshooting, the experience should be summarized in time, and maintenance and repair records should be made. The purpose of the records is to serve as a file for future reference during maintenance.<\/p>\n\n\n\n
