The W12NC-40x2500 4 Roller Plate Rolling Machine adopts a four-roller structure, and the above roller is mainly driven, and the torque is generated when the plate is bent by the urging force between the moderator gear and the upper roller gear. The lower pressing roller applies a force to the crimping force by hydraulic oil in the hydraulic pipe to fix the plate to the side pressing roller on both sides of the inner wall of the lower pressing roller, and to make the tilting movement along the guide wheel; and to provide driving through screws, nuts, worms and lead screws. The advantage of this machine is that the initial bending and rolling of the top end of the plate can be performed on the same machine.
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.
Heady duty linear sliding guides mounted on the uprights of the machine for lower roller and side rollers translation
Electronic parallelism control system
Rrollers synchronization and balancing control fully electronically controlled
Side rollers and bottom rollers variable tilting controlled, positive or negative
Rollers driving by independent hydraulic motors
Anti-friction material in sliding area
Instantaneous brake for rollers rotation for high safety
Reversal side hydraulic driving
Mobile control panel station, with low voltage control
Mobile control push-buttons, convenience for operator
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, JOBEST 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.
