Four roller rolling machine
The machine adopts the four roller structure with the upper roller and lower roller as the drive, and provides the plate materials with torque through the engagement of the planetary reducer with the upper and lower roller, the lower roller can make vertical movement so to clamp the plate materials tight. On both side of the lower roll with the side-roller can be driven by hydraulic cylinder to make arc-down. And four rollers all used the spherical roller bearings.
