6-Roller CNCPlate Rolling Machine

In recent years, plate rollingmachine manufacturing techniques are constantly updated along with thecontinuous development of domestic and foreign economic construction. Atpresent, plate rolling machines used in the market include 3 roller symmetricaltype, 3-roller asymmetric type, 4-roller type, upper roller universal type andhorizontal down-adjusting type etc. When working, the roller body on the topand under the lower bends the plate material along its cylindrical surface andhas a uniform motion to finish the bending, arc and correcting round of platematerials etc. procedures.

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

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

    The plate rollingprinciple: The machine has astructure of 6-roller type, in which upper roller is active and it can connectupper roller through the output shaft of a reducer. Upper roller can have arotating motion on the symmetrical position of the center of both lower rollersto realize the running of plate materials. Upper roller is fixed on stand,lower roller and supporting roller are mounted on slider device, it can beobtained through hydraulic oil acting on piston along horizontal motion insidehydraulic cylinder to keep lower roller and supporting roller a lifting motionin order to press plate materials. When top pressure of lower roller excessyield stress of plate, the rolled plate shall be out of shapes

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

The machine are applied in processingvessels with thickness ≤8mm, diameter ≤500mm, mass, high efficient and highroundness of containers, and it can also be programmable to roll to roundcorner with square fuel tank, as well as ellipse and round etc. differentshapes.
