W12 4-rollers Hydraulic Plate Rolling Machine
Structure style:
It belongs to four roller plate rolling machine. It is 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 bottom roller and side rollers rotate. And supply the torque for bending plate. The bottom roller, side roller and drop end are all driven by hydraulic oil tank. 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.
Performance features:
It’s easy to operate, rich shape bend;
CNC control, digital readout for position of each rollers. High accuracy and precision circle;
Full hydraulic drive, high efficiency and energy saving, the drive power is equivalent to the traditional 60%;

Once forming, the productivity is higher50%-80% than three roller bending machine;
Aligning the material is convenient and accurate, avoid the wrong side phenomenon;
Cone bending device;
Permanent lubrication(bearing life without refueling);
The top and bottom roller clamp the plate during rolling without slipping;
The min bending diameter of the cylinder can get to 1.1 times the diameter of the top roller, the surplus flat edge smaller than any type of other plate rolling machine;
The carrying device and feeding device and support device can be installed easily;
CE certificate.
