Method for manufacturing large-diameter folding table radial plate wheel

The invention discloses a method for manufacturing a large-diameter folding table radial plate wheel. The method includes the following processes of blank sawing, heating before forging, forging, rolling and bending, wherein the forging process includes pressing to form a folding table of a wheel radial plate on a forming blank during wheel forming, and reasonably distributing metal quantity inside and outside the folding table at a preforming stage; the rolling process includes enabling interference not to be generated between a radial plate roller during rolling and the folding table, and reserving a noncontact angle between an inner diameter face of the wheel and a profile of the radial plate roller; the bending process includes adopting a bending mode of enabling a bending die to be fitted with a concave-side radial plate of the folding table during bending, and reserving a space at a position, close to the folding table, of the bending die during positioning of the bending die. By the method, potential risk generated to the folding table radial plate wheel by a conventional wheel rolling method is avoided, metal yield and production efficiency are improved, and stable and mass production of the wheel is realized.
