1) The machine adopts 3-roller symmetrical structure with the upper roller moving vertically in the center between the two lower rollers, which is achieved through the drive of the screw, the unit, the worm and the lead screw.
2) The two lower rollers rotates and provides the plate materials with torque through the engagement of the output gear of the moderator with the gear of the lower rollers.
3) Adapted for bending metal plate into round, arc, and so on. Its working principle is rotary bending deformation. This product is widely used in chemical industry, Cement, shipbuilding, boiler, aviation, water control project, Power Transmission Tower, metal structure and the industry of making machinery.
