This machine is a roller non parallel typeThe main features of the model are:

Main drive systemUpper and lower rollersFor full main drive, it is driven by two motors, capable of emergency stop braking, with a soft start device, minimal impact on the power grid, reliable performance, low noise, and compact structure.

Up and downSupporting rollerFor multi column diameter support, arranged in a board like pattern with the work roll, and equipped with an integral inclined iron adjustment mechanism at the bottom,Manual fine-tuning methodAdjust up and downFlattening rollerRoll shape, to maintain the rigidity of the work roll, when flattening thin plates with wave bending, convex concave and ladle bending deformation, it is necessary to use support rollers to change the convexity of the work roll,hand movementAdjust itFlattening rollerThe opening amount and inclination angle can easily adapt to correction requirements such as wave bending and scoop shaped plates.

All work roll necks are equipped with rolling mill specific self-aligning needle roller bearings, which have higher transmission efficiency and longer service life compared to copper sleeves. The friction resistance of the work roll is small, and the non slip conditions are greatly improved, which can correct thinner steel plates;

Adopting a closed frame, the correction force is internally enclosed, and the frameThe appearance is simple, the overall rigidity is good, and it can be fully loaded and leveled without laying the foundation；

The downward turning mechanism and the turning mechanism are integrated using group technology, utilizing two identical power systemsYEJ type motor drive enables the movable crossbeam to accurately and automatically position and quickly swing angles;

Set a larger lifting height on the activity crossbeamConvenient for machine roll replacement and maintenance;

Using an electric dual line oil feeder for centralized lubrication, separate lubrication is applied to lubrication points such as the working roller, support roller bearings, worm gear box, and screw through the electric dual line oil feeder and dry oil pipeline;

Advanced measurement and electrical control systems,The equipment adopts Siemens from GermanyPLC S7 control. On the control panel, the inlet and outlet pressure can be set according to parameters such as plate thickness, plate width, material, and original curvature. PLC has the function of editing, storing and memorizing process parameters, which can be called and corrected at any time;

Complete protection functionsThe exposed rotating body such as the drive shaft is installed with a protective cover, and the feeding port is protected by a photoelectric switch.

As shown in the figure, this machine consists of frame assembly, work rollers, support rollers, stop wheel device, movable crossbeam, lower crossbeam, downward angle mechanism, balance device, displacement sensing device, main transmission device, grease lubrication system, electrical control system and other parts.

The design, manufacturing, and experimentation of equipment and instruments comply with international industrial standards（ISO）。 This machine tool not only has sufficient rigidity and wear resistance, runs smoothly, but also has a reasonable structure, high stability, reliability, and durability, and is easy to operate and maintain.

upperarrangerollerCompared to the lower row of rollers, there is one less roller, which allows for overall lifting and tiltingAdopting a non parallel correction method with a small inlet opening and a large outlet opening to make the steel plateDuring the leveling process, multiple rounds of forward and backward bending are performed for leveling,From large to small and then to elastic deformation,The Bauschinger effect gradually transforms multiple primitive curvatures into a single curvature, ultimately resulting inboardFlatten.Non parallel correction methodsymbolThe correction law of the composite board reduces the energy consumption of the main motor and improves the service life of the moving parts. Power saving15-30%, high leveling accuracy, few leveling times, high efficiency, beautiful appearance, and reasonable structure. The upper and lower roller grouping drive and its advantages will be introduced later.
