W12NC-8x1500 4 Roll Plate Roller with four rollers adopt upper roller rotary mechanical drive, lower roller and side roller fluctuation hydraulic drive, electric concentrated control operation system. This machine can complete pre-bending and pipe shaped rolling for one material feeding, arc or moderate taper shaped material can be pre-bend in this machine with minimized residual straight margin and high work efficiency, it also can do the work of approximate leveling for metal plate to be processed. The machine equipped with NC System control, improve automation level. It is widely used in petroleum, chemical boiler, shipbuilding, metal structure and mechanical manufacturing industry.
Totally European design,streamlined looking,frames of our machines are fabricated, welded steel (ST-52).
Roll shafts, materials and bearings used in production are European quality. Also the torque limit of the machines is very high.
CNC playback and CNC graphic control systems are available as optional accessory.The main structure of the equipment includes upper roller, lower roller and horizontal movement mechanism, supporting mechanism,main drive mechanism,downturn system, left and right machine frame, chassis and balance mechanism, hydraulic and electrical control systems.
The model MH has both the upper and the lower roll powered with hydraulic motor and planetary gear box.
High precision pre-bending, freely setup the width of plate.
Upper roller presses the plate end for pre-bending.Upper roller likes drum with collaboration of carrier roller permit continual bending of any thickness of plate.Safe work, fixed two down roller, upper roller does horizontal and vertical movement, and the plate don't move during upper roller moving.
Unitary structure, convenient to move the whole machine as machine has a hardy under pan. No need to anchor bolt.
Different use has different control way, like top numerical control and below numerical control.Through exclusive technology, we can develop cones as easily as competitive machines can develop cylinders.
And it eliminates scarring on the surface of shell or roll and also eliminates, in most cases, the need for grinding the lamination (bullnosing) on the minor diameter edge.
