W12 CNC hydraulic 4-rollers plate Rolling machine full auto 4-rolls Bending machine
Main characteristic:
The structure of the machine is four roller type, the upper roller is the main drive, and the output gear of the reducer is meshed with the upper roller gear to provide torque for rolling plate;
The lower roller makes a vertical lifting movement, which is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston, so as to clamp the plate, which is hydraulic transmission;
Side rollers are arranged on both sides of the lower roller, and tilt along the guide rail of the frame, which are driven by screw nuts, worm gears and worms;
The advantage of the machine is that the plate end pre bending and rounding can be carried out on the same equipment same time.
The main features,
- Ferrules in full circle or varying radius can be done easily;
- Pinch roller and lateral rollers move with hydraulic pistons in orbital way
- Overload protect
- Top roll powered by hydro motor and planetary gearbox
- Three digital read outs for easy roll positioning
- Hydraulic drop end for easy removal of finished ferrule
- Easy operation with mobile control panel
- Hydraulic balancing system
