Rolling Machine

The machine widely used in petroleum, chemical industry, cement, bioler, shipbuilding, aviation, water conservancy, power transmission towers and other machineary and equipment. Its working principle is rotating bending deformation. For the upper roller can be woved no matter up and down, but also horizontally, so no need additional press or equipment, can realize bending, as well as correction of the workpiece.

1.The machine adopts 3-roller symmetrical structure with the upper roller moving vertically in the center between the lower rollers, wihch is achieved through the drive of the screw, the unt, the worm and the lead screw.
