The invention provides a steel drum W-shaped rib roller with high strength, reasonable structure and convenient transportation. The steel drum W-shaped rib roller comprises a base, a left box body, a right box body, an upper press roll mechanism, an entrust material mechanism, a pneumatic system, a hydraulic system and an electrical system; the base is provided with a guide rail and a lower oil cylinder; the left box body and the right box body comprise box bodies, input shafts, output shafts, lower press rolls, sliding seats and motors; the upper press roll mechanism comprises an upper oil cylinder, an adjusting thread bush, a sliding block, a shaft and an upper press roll; and the entrust material mechanism comprises a rubber roller, a supporting bracket, a supporting seat, a cylinder seat and a cylinder. The steel drum W-shaped rib roller has the advantages that the steel drum W-shaped rib roller has reasonable structure, two W-shaped ring ribs are processed in the middle of a drum body to replace two prior large ribs, and the steel drum W-shaped rib roller reduces the largest outside diameter of a steel drum on the premises of not reducing the strength of the steel drum and reducing the capacity, and greatly facilitates the transportation.
