4 Rollers Hydraulic Rolling Machine 
Product Introduction:
This machine is with four rollers structure ,which can do pre-bending and bend works at one time .
The upper roller is the main driving roller,
down roller and two side rollers up-and-down movement are controlled by hydraulic motor.
The up-and-down displacement of the down and side rollers are controlled by PLC.
Automatic leveling,display by screen , high synchronization precision can reach ±0.2MM.
Turnover bearing body dumping and reset is done through hydraulic transmission. 
1.The four-roller bending machine adopts a torsion-axis synchronous structure,
and the four-roller rolling machine has high precision and roundness .
2.Full hydraulic motor drive, four-roller rolling machine is environmentally and high efficiency.
3.The four-roller rolling process is completed in one time, including the works of pre-bending.
It's fast, efficient, and easy to operate,one operator can do all works .
4.With automatic alignment and clamping function, the plate will not slide and run off.
5.The four-roller bending machine has anti-overload and hydraulic protection functions.
6.It can do works of smaller diameter required by special demand .
