Maintenance inspection and operation of leveling units

  • JIUZH 

The main work content of leveling unit in maintenance is to pay attention to lubrication, tightening and inspection. Due to the level of work directed by the head of the mechanical components and cleaning and maintenance group, 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 necessary adjustments. If faults are found, make sure that the mechanical components and parts have good working performance.
The use of unit testing, mainly can test and adjust the leveling unit, troubleshooting the problems of each part, balancing the degree of wear and tear, will inevitably affect the performance of each part and the diagnosis and inspection of fault symptoms. Some countries test, and then complete the necessary replacement, adjustment and troubleshooting work after the third level of maintenance requires technical integrated service personnel and advanced testing instruments and tools.

Tension controller on the leveling unit will also be set according to the detection of slitting 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, which should pay attention to the selection of the given torque. Because of this, the mechanical operation process can also maintain a constant tension, deceleration work in order to make the working conditions stable. Similarly leveling machine in continuous operation, the leveling technology removes the unit of material, that is, eliminate the pressure of the material. For the level of the plate, the basic principle of roll leveling is to pay attention to the selection of the material elastic extension, the yield point of the lower part of the material, so that the “fiber” part in the short ratio of the scalability to obtain the “fiber length”.
The realization of the leveling group will also allow the material to pass through the machine. Circular letters with a small radius of curvature will then bend, causing the short “fibers” of material to rotate. As the sheet metal moves in the same direction as the machine exit, the bending decreases from top to bottom, eliminating the level of the machine entrance of the leveling group. With severely bent and deformed material, the plate is flattened, or “flattened”, as long as the material is almost the same length as all the fibers.
