WC43 series plate straightening machine is integral lifting roller leveler with many top rolls. All top rolls are fixed on the movable crossbeam, and are lifted along with the movable crossbeamwhich isdriven by two lifting mechanisms, each mechanism is made up of a motor. Two worm reduction gears and screw nut pairs. The two mechanisms can work at thesame time, and can work separately. That is to say the feeding hole and discharge hole of the working roll can produce equal state and unequal state to make it easy for traveling and levelling of sheet metal, the height at the feeding and discharge ends of the top roll are displayed accurately through two displacement sensors and the display screen.

The characteristic of this series leveler is that it has adopted two national patent technologies: Group driving plate levelling machine ZL200420001176.0 and axial decelerating motor leveler ZL200520007514.6. Each top roll is driven by a set of decelerating motor. And every two lower rolls are driven by a set of dynamic system, so that the line speed of each roll is consistent with sheet metal speed of the contacting part, and it has solved the problems existing in traditional transmission system, such as friction between sheet metal and roll surface. And mechanical interference problem in the system And the working roll adopts spherical roller bearings which have little friction resistance. So this series leveler has such advantages as high levelIing quality, Iittle noise, low energy consumption and environmental protectioncompared with traditional levelers.
