| This four-roller roll-bending machine, is used to pre-bend and coil in the industries such as the pressure container, machinery, hydroelectricity, architecture. It also has the function of coiling and leveling.
The upper is the main drives. It drives the lower roller and side rollers through the friction force between the plate and the rollers, which offer the torsion for the coiling.
The upper roller is droved by motor, lower roller, side rollers, reversal frame and supporting rollers are hydraulic transmission.
The lower rollers move vertically, side roller move slant, synchronization precision is ?ܠ??.15mm.
Pre-bending is made by the lower roller ascending to nip the plate, the side rollers ascending to complete the end pre-bending of the plate.
This machine has the symmetry bending and asymmetry bending capacity through change the position of the side rollers
This machine adopts the central lubrication system.
The control system is employed the OMRON PLC.
Lower roller and side rollers position sensor adopt the light encoders to supply the high accuracy.
