Feature
- CNC Four rollers hydraulic plate rolling machine
- With Prebending
- Prebending & rolling can be automatically achieved one time on one working cycle.
- Top roller is powered roller
- Lifting of bottom roller and two side rollers driven hydraulically
- Displacement of bottom roller and two side rollers lifting controlled by CNC
- Display on screen for displacement
- Synchronous precision ±0.1mm
- Balance at the tail of top roller for conveniently unloading finished workpiece
- Independent operating station
- with safety interlocking

- Bending of conical and cylindrical shells available

- Two side rollers makes arc moving by hydraulic cylinder

- With electrical synchronous system to avoid misalignment

- Permanent free lubricating technology in the life of bearing

- Adjustable clamping force without slipping, whose efficiency is higher 50~80% than 3-roller plate bending
machine

- Rear side roller at lifting can align sheet to ensure minimum difference for each cylindrical shell

- Shortest straight edge by prebending of front side roller in arc moving
- Convenient cone bending with larger taper

- Arc swing side roller with enlarger forming force under level effect

- Synchronization for two sides of pressing roller by proportional valve with higher rolling precision

- Easy operation
