Automatic Hydraulic 4-roll Plate Rolling Machine can pre-bend the ends of plate and then roll it to specified shape with one time loading without reversing it.
| Quantity: | |
|---|---|
This machine can pre-bend the ends of plate and then roll it to specified shape with one time loading without reversing it. The working rolls on this machine are driving rolls and the lower rolls and two side rolls are hydraulically driven to move vertically. This machine is applicable to bending steel plate and can roll plate to cylindrical, arc or conical workpiece. It can also pre-bend ends of plate and center the plate, so rolling accuracy is high with small residual flat edge and high working efficiency. The steel plate can also be roughly flattened on this machine.
