W12 Hydraulic Plate Rolling Machine with 4 Rolls

Working Principle

Structure Style

It belongs to four rollers plate rolling machine. It is wide used in the manufacture of pressure vessels, machinery, hydropower, construction and other industries of the barrel body pre bending, roll round, and also have a function of checking circle and leveling. The top roller driven by hydraulic motor. Through the friction between the metal plate and the top roller to drive the botton roller and side rollers rotate. And supply the torque for bending plate. The botton roller, side roller and drop end are all driven by hydraulic oil tank. The botton roller move up and down, the side roller move along with an arc. The botton roller rising to clamp rising to clamp the plate and the side title up to pre-bend the end of the plate.
