Leveling unit in the maintenance of the main work content is to pay attention to lubrication, tightening and inspection. Due to the level of work directed by the mechanical parts and cleaning and maintenance group leader, the operator of the leveling unit should focus on checking and adjusting the reducer and gear transmission mechanism, straightening equipment and electrical system, and then make the necessary adjustments. If a fault is found, ensure that the mechanical components and parts are in good working order.
The use of unit testing, mainly can test and adjust the leveler unit, eliminate the problems of each part, balance the degree of wear, is bound to affect the performance of each part and the diagnosis and inspection of fault symptoms. Some states require technical integrated service personnel and advanced testing instruments and tools for tertiary maintenance after testing and then completing the necessary replacement, adjustment and troubleshooting work.
The tension controller on the leveler unit will also be set according to the detection of cutting and winding speed and diameter, load torque, tension and other calculation parameters, tension control can output standard 0 to 10V, and then sent to the inverter through the analog signal, this time should pay attention to select the given torque. Because of this, the mechanical operation process can also maintain constant tension, deceleration work to make the working condition stable. The same leveler in continuous operation, flatten technology to remove the material unit, that is, to eliminate the pressure of the material. For the level of the sheet, the basic principle of roll flattening is to pay attention to the choice of material elastic extension, the yield point of the lower part of the material, so that the part of the "fiber" can stretch in the short ratio to obtain the "fiber length".
The implementation of the leveler cluster will also allow materials to pass through the machine tool. Circular letters with a small radius of curvature 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, eliminating the level of the machine tool entrance of the leveler unit. A severely bent and deformed material is flat, or "flattened," as long as the material is nearly the same length as all the fibers.
