In recent years, plate rolling machine manufacturing techniques are constantly updated along with the continuous development of domestic and foreign economic construction. At present, plate rolling machines used in the market include 3 roller symmetrical type, 3-roller asymmetric type, 4-roller type, upper roller universal type and horizontal down-adjusting type etc. When working, the roller body on the top and under the lower bends the plate material along its cylindrical surface and has a uniform motion to finish the bending, arc and correcting round of plate materials etc. procedures.

But the existing plate rolling machine still has many shortages, such as the distance between upper roller and lower roller has a slow adjusting speed, the central distance of lower roller has a limitation in some extent, the entire work must go through multi-times of rolling with a lower efficient, Small diameter of work piece is very difficult to roll as well as it is unable to mass production etc problems. The utility model of plate rolling machine will solve the following technical problems, namely overcome existing technical shortages, provide a kind of 6-roller plate rolling machine which can fast roll small diameter work piece and can be formed in a circle.    

Compared with existing technique, the utility model of 6-roller plate rolling machine has beneficial effects that it can directly roll small diameter work piece, because of a special process between upper roller and lower roller and adjustable central distance of the lower roller, it increase anti-slip ability, reduce the requirement for straight edge length and lower roller height adjustment with limit adjusting device in favor of high efficient of rolling mass work pieces. The rolling process can be formed from many times to a circle. The lifting device can  make the adjusting time of the lower roller from ten minutes down to a few minutes, a few seconds.

    The plate rolling principle: The machine has a structure of 6-roller type, in which upper roller is active and it can connect upper roller through the output shaft of a reducer. Upper roller can have a rotating motion on the symmetrical position of the center of both lower rollers to realize the running of plate materials. Upper roller is fixed on stand, lower roller and supporting roller are mounted on slider device, it can be obtained through hydraulic oil acting on piston along horizontal motion inside hydraulic cylinder to keep lower roller and supporting roller a lifting motion in order to press plate materials. When top pressure of lower roller excess yield stress of plate, the rolled plate shall be out of shapes

    Applications: the machine is widely used in plate making and printing industry, auto fuel tank; acetylene cylinder etc. small and medium diameter of mass pressure vessel products.

The machine are applied in processing vessels with thickness ≤8mm, diameter ≤500mm, mass, high efficient and high roundness of containers, and it can also be programmable to roll to round corner with square fuel tank, as well as ellipse and round etc. different shapes.
