The present invention comprising the steps of present invention relates to heavy duty vehicles and tire rim forming method for farm machinery, to more specifically to lower the upper mold was inserted perpendicularly to the material in a circular tube shape on top of the lower die flaring a lower end portion of the material , upper and to press contact the first forming roller to the outer peripheral surface of the material to rotate with the lower mold and the step of chukgwan the central portion of the material, to press contact the second forming rollers in the upper outer peripheral surface of the material to chukgwan the upper portion of the material steps and, by press-contacting the second forming rollers in the upper outer surface and the upper end of the material and the step of cold forging the upper end portion of the material, while moving the second forming roller on the outer peripheral surface of the materials up and down after the pressure contact the outer circumferential surface of the material, by configured to include the step of chukgwan the whole, greatly simplified equipment and simplified compared with the conventional press bending method and a roll Fair to heavy duty for small quantity batch production can be more easily and molded easily tire rim for heavy vehicles and agricultural machinery as required by due to the initial costs too much to allow domestic production of heavy vehicles and agricultural tires wheels that rely only on imports It relates to a vehicle tire rim and forming method for farm machinery.
