The Trailer Plate Bending Machine

This upper roll of this machine not only can carry out vertical fluctuation but also can carry out level migration, the vertical fluctuation is the hydraulic transmission, it obtains the level migration through the hydraulic cylinder in hydraulic fluid act on connecting rod. Through the turbine bar box, the turbine wheel pole, the screw mandrel organization transmission torque, drives the upper roll the level migration, the lower roll only makes the rotary motion to provide the torque for the plate bending machine, the supporting roller which can be adjust is equipped under the lower roll, the upper roll assumes the drum shape, it can enhances the straight dimension of the product. It is suitable with the each kind of section shape shell bending of the trailer.
