Static maintenance of the press - refers to the maintenance of the machine while the machine is in a static state. 1. Establish rules and regulations for machine maintenance Offset machine maintenance should be based on the machine's instructions. Such as regular oil change, cleaning filters, regular inspection of machine accuracy. 2. Strengthen the maintenance of important components Gears, cams, sprocket, rollers, and bearings are the most important parts of the press. Their maintenance must be different from other parts because their accuracy will affect the final print quality. The spring is the most used component of the force balance mechanism on the machine. Their work directly determines the accuracy of the mutual motion of the moving parts. The spring must be sensitive to elasticity, while the elasticity and the non-recoverable plastic deformation are the work of the spring. Extremely disadvantageous. If you find the above problem, you need to replace the spring immediately. 3. Conduct technological reforms to strengthen machine maintenance Machine maintenance requires the machine to fully consider the convenience of machine maintenance when designing. Shanghai Printing However, due to the complexity of the printing press, it is obviously impossible to take every factor into consideration, and the environment changes and the contents of machine maintenance will also change. Therefore, structures that are not conducive to machine maintenance should be improved without affecting normal work. Dynamic maintenance of the press - refers to the maintenance of the machine while the press is in a dynamic state. 1. Machine preparation status detection How the machine is prepared can be detected by jogging or turning. Such as tools and other items stuck in the machine; whether the appropriate installation position of the printing plate, if not appropriate, may cause damage to the printing plate or make it difficult to find rules; if the blanket is installed properly, if it is not suitable, it is possible. Causes printing failures. In severe cases, the blanket or machine may be damaged. 2. Lubrication of the machine First, through the oil standard, you can observe whether the oil path of the machine is unblocked. If the oil mark is not oily or the oil mark is not clearly observed, you should urgently stop and carefully inspect the oil path for oil leakage. Although the oil leakage of the machine is easy to observe, it is difficult to find the reason. For a machine such as a sliding bearing, low speed is not conducive to its lubrication. In particular, the point-of-action or low-speed operation has a great influence on its lubrication. Therefore, it is advisable to idle the machine for lubrication before performing this type of operation. This is a top priority for daily work. In Shanghai, the oil pump of some machines is driven by the host computer. Therefore, when the reverse point is reached, the oil line will not only be refueled, but will also suck the oil from the oil line back into the tank. This is very dangerous, so counter points should be avoided. Lubrication of some of the more important parts can also be detected by the temperature of the metal in the vicinity. If the temperature is too high, it indicates a problem with lubrication. 3. Impact during machine operation The smaller the impact during the operation of the machine, the more conducive to printing, but also can extend the life of the machine. Reducing printing pressure (in a broad sense, pressure) is an important condition for ensuring the smooth operation of the machine. Under the premise of ensuring the quality of printed products, the printing pressure should be as small as possible. Reducing the speed of the machine is another important condition for reducing the moment of inertia of the machine. The lower the speed of the machine is, the smaller the moment of inertia is, so the machine should not be kept at a high speed all the time.
