2000mm~3000mm Hydraulic Metal Plate Rolling and Bending Machine

The 3-roller hydraulic plate rolling machine has 3 symmetrically-arranged rolls. Its upper roller is located at center of two lower rollers and is directly driven by dual hydraulic cylinders to perform vertical movement. The output gear mounted on the main speed reducer is used to mesh the gears on the 2 lower rolls for rotatory motion so as to provide torque for the plate. With the pressure exerted by the upper roller and the rotary motion of the lower rollers, the metal plate placed among the three working rollers will be bent continuously and finally come into a permanent plastic deformation. In this way we will get the plate with required shapes such as cylinder, taper cylinder or arc, etc. Disadvantage of this kind of hydraulic plate rolling machine is that the end of plate could not be bent in advance, but it can realize that when checking the roundness. With a motion detector and a digital meter for the upper roller, operators will be able to directly observe the position of the roller, helping to improve the working efficiency dramatically.
