The top roller is driven by hydraulic motor. Through the friction between the metal plate and the top roller to drive the bottom roller and side roller rotate. which supply the torque for bending plate. The bottom roller, side roller and drop end are all driven by hydraulic pressure.
It belongs to four roller plate rolling machine, which widely used for the pre-bending and tube rolling in the industry of pressure vessels, machinery, hydropower, construction etc. Meanwhile, this 4 rolls rolling machine also have a function of roundness correction and leveling.
The top roller is driven by hydraulic motor. Through the friction between the metal plate and the top roller to drive the bottom roller and side roller rotate. which supply the torque for bending plate. The bottom roller, side roller and drop end are all driven by hydraulic pressure. The bottom roller moves up and down, the side roller moves along with an arc. The bottom roller rising to clamp the plate and the side roller title up to pre-bend the end of the plate.
