The main work content of the 　　 leveling unit during maintenance is to pay attention to lubrication, tightening and inspection. As the level of mechanical components and cleaning and maintenance team leader guide the work level, the leveling unit operators should focus on checking and adjusting the reducer and gear transmission mechanism, straightening equipment and electrical system, and then make necessary adjustments. If a malfunction is found, please make sure that the mechanical components and parts have good working performance.

　　Using unit testing is mainly to test and adjust the leveling unit, eliminate the problems of each part, and balance the degree of wear, which will inevitably affect the performance of each part and the diagnosis and inspection of fault symptoms. In some countries, testing, and then completing the necessary replacement, adjustment and troubleshooting work, the three-level maintenance requires technical comprehensive service personnel and advanced testing instruments and tools.

The tension controller on the 　　 leveling unit will also be set according to the detection of slitting and rewinding speed and calculation parameters such as diameter, load torque, tension, etc. The tension control can output standard 0 to 10v, and then send it through an analog signal Inverter, you must pay attention to selecting the given torque at this time. It is precisely because of this that a constant tension can be maintained during the operation of the machine, and the working condition can be stabilized by decelerating work.

When the 　　 leveling machine is running in a group, the flat pressing and leveling technology removes the unit of the material, that is, eliminates the pressure of the material. Regarding the level of the plate, the basic principle of roller flattening is to pay attention to the elastic extension of the material selection, the yield point of the lower part of the material, so that the "fiber" part has stretchability in the short ratio, so as to obtain the "fiber length". .

The realization of the 　　 leveling machine group will also allow the material to pass through the machine tool. The circular letter with a small radius of curvature will then bend, causing the short material “fiber” to rotate. When the metal plate moves in the same direction as the machine tool outlet, the bending amplitude decreases from top to bottom, which eliminates the level of the machine tool inlet of the leveling unit. For heavily bent and deformed materials, as long as the material is almost the same length as all fibers, the board is flat, or "flattened".
