The invention discloses a once-forming technology of a belt wound type five-drum all-steel radial ply tire. Parts which need to be bonded are bonded into a tire cylinder A on a tire bonding drum, the tire cylinder A is rotated on a forming drum II to wait, a belt layer composite part B is manufactured on a station I of the belt bonding drum, the belt of the belt layer composite part B is wounded by steel wires to obtain a belt layer composite part C, the belt layer composite part C is bonded with a tire surface to form a tire surface and belt layer composite part D, the tire surface and belt layer composite part D is combined with the tire cylinder A to form a tire blank E, and the tire blank E is formed to obtain a finished product. The invention adopts a wound type to manufacture the belt layer, avoids a lapping phenomenon of a joint, can satisfy the high-performance requirements of dynamic balance, uniformity, and the like of the all-steel radial ply tire, and the five-drum forming device is used for satisfying the technical requirements of the technology and increases forming production efficiency.
