Lower roller arc down adjustable plate rolling machine,plate bending machine:   Company introduction of foreign product technology, combined with the characteristics of domestic products, the development of the development curve down three roller bending machine and its performance advantages in the domestic similar products, with high efficiency, low power, easy to operate, and other characteristics.
Arc three roller bending machine, three roll for the drive roller, dynamic through the hydraulic motor planet reducer, coiled sheet provide torque, workpiece and the roller surface are basically no mutually sliding; and through a hydraulic cylinder driven arc lifting motion. Three and all adopt spherical roller bearings. The advantages of the machine is a loading without requires the use of auxiliary device that is able to complete the two ends of the plate material pre deformation and volume of barrel shaped, curved work, can also reshaping and leveling work on the metal plate material, and the remaining little straight edge.
