This model pertains to the four-roll plate rolling machine, which is employed for the pre-bending and circular rolling of cylinders in industries such as pressure vessels, machinery, hydropower, and construction. It also possesses the function of plate leveling. The upper roller is primarily driven by a hydraulic motor, and the lower roller and side roller are driven to rotate via the frictional force between the steel plate and the roller, thereby providing torque for plate rolling. The lower roller, side roller, and overturning frame are all hydraulically actuated. The lower roller moves vertically up and down, and the side roller moves up and down along an arc. Pre-bending is accomplished by the lower roller rising to hold the steel plate, and the side roller tilting and rising to pre-bend the end of the plate. • 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 higher 50%- 80% than three roller bending machine; • Aligning the materialis convenient and accurate, avoid the wrong side phenomenon; B Cone bending device; • Permanent lubrication (bearing life without refueling); • The top and bottom roller clamp the plate during rolling without slipping; • The minimum 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 carying device and feeding device and support device can be installed easily;

Stepl : The steel plate has been properly aligned.• Lower the side rolls on the discharge side.• Initiate the reverse rotation of the upper and lower work rolls to convey the steel plate in the opposite direction of the feed direction. • When the rear edge of the steel plate is approximately centered between the upper and lower work rolls, halt the reverse rotation. At this stage, the steel plate is in the pre - bending position. • CNC Plate Rolling Machine Workshop • Elevate the side roller (on the feeding side). Move the side roller in an upward direction to partially pre - bend the steel plate....

Step3: Continue pre - bending• Initiate forward rotation. • Rotate the upper and lower work rolls to convey the steel plate in the feeding direction. • Cease the forward rotation when the steel plate reaches the position depicted in the above figure. • Measure the radius using a radius gauge and make corrections if required. • Initiate the forward rotation. • Rotate the upper and lower work rolls and continue to feed the steel plate in the feeding direction. • When the steel plate reaches the position depicted in the above figure, halt the forward rotation. • Lower the side roll on the feeding...
