Cutting machine maintenance is the general term of machine maintenance and repair. Maintenance is the daily flow of maintaining the technical functions of equipment, while repair is the flow of troubleshooting and restoring the technical functions of equipment. During the use of the cutting machine, due to various wear, erosion, fatigue, deformation, aging and other phenomena of parts, the accuracy and function of the cutting machine will be reduced, which will affect the product quality. In severe cases, the equipment will be shut down. Cutting machine maintenance is a kind of technology flow adopted to maintain and repair the machine, reduce its deterioration, extend its service life, and maintain or restore the designated functions of the machine. The homework content of cutting machine maintenance includes equipment inspection, adjustment, lubrication, timely handling and presentation of abnormal phenomena. In order to ensure the normal operation of the machine, reduce wear, protect accuracy and extend service life, proper lubrication, maintenance and servicing are necessary.
1、 Inspection of the cutting machine The inspection of the cutting machine is mainly a daily inspection. The main contents are vibration, abnormal sound, looseness, temperature rise, pressure, flow, etc. of relevant equipment. Generally, the function and working state of the machine can be judged from the appearance of the running state of the equipment by sense, simple instruments, and the state of processed products. Such as the temperature, pressure and speed of the bearing of the mechanical cutting machine, blanking accuracy, noise, oil quality and leakage of the hydraulic cutting machine, etc. In a word, the inspection position, cycle and other contents shall be determined according to the complexity of the cutting machine, the characteristics of the function, and the importance to the product quality, so as to formulate the repair position, time and technical preparation. The inspection work is generally the joint responsibility of operators and maintenance workers
2、 The lubrication of cutting machine The lubrication of cutting machine is an important measure to reduce the wear of parts in operation and avoid failures. Poor lubrication of the bearing of the mechanical cutting machine leads to fever, seizure and other accidents. Therefore, lubrication is one of the important contents of the cutting machine maintenance. Implement the “Five Determinations” method of lubrication, which standardizes and institutionalizes the daily lubrication work, refines the content, and is simple and easy to remember. The details are as follows: 1. Fixed point: determine the lubrication position, lubrication point and inspection point of the equipment. 2. Fixed quality: use oil according to the grease brand specified in the machine copy list. 3. Quantitative: determine the amount of oil added to the lubricating parts of the equipment to prevent extravagance and manage oil leakage of the equipment. 4. On schedule: add oil, add oil and clean oil according to the time specified in the machine copy sheet to ensure timely lubrication. 5. Fixed person: determine the operator or maintainer of lubrication work, and assign the responsibility to each person.
3、 The daily maintenance of the cutting machine is in the charge of the operator. Operators must know the equipment structure and observe the operation and maintenance procedures. 1. Before the work starts (shift change or intermittent work), the main department of the machine should be checked and filled with lubricating oil. 2. Use the equipment in strict accordance with the equipment operation procedures in the class, pay attention to the operation of the equipment, and timely handle or give a speech when finding problems. 3. Before the end of each shift, a cleaning work shall be carried out, and each friction surface and bright surface shall be coated with lubricating oil. 4. Under the normal two shift working condition, the machine shall be thoroughly cleaned and inspected every two weeks.
4、 Technical safety precautions: 1. After the machine is installed, it is necessary to ensure that the safety protection devices are complete and the lines and pipelines are complete. Properly ground the electric motor. 2. When repairing, adjusting, oiling, wiping and checking the machine, the power supply must be cut off first to avoid danger. 3. Before turning on the trigger, you must pay attention to the surrounding environment to see if there is anyone working under the machine. 4. When doing homework, it is not allowed to place any irrelevant items such as oil jug and tools on the workbench. 5. If an accident occurs after driving, or there is abnormal machine noise and jamming, it is necessary to park immediately for inspection.
