The W12NC-25x3000 4 Roll Plate Roller has pre-bending function for plate edge ,and can bend roll the plate one time without any thing re-rolling with combined procedure or prebending and bending roll into shape. The upper roller is the main drive roll, the down roller and two side rolls up-and-down movement is controlled by hydraulic drive. The up-and-down displacement of the down and side rollers are controlled by computer..Automatic leveling,display by screen , high synchronization precision ±0.2MM.Turnover bearing body dumping and reset is done through hydraulic transmission.The upper roll end has balance equipment to be convenient take of the rolled cylinder and workingpieces.There are moveable independent operation table for easy moveable operation.
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, Krrass 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.
