Rolling mechanism for bicycle hub and hub manufacturing method

The invention relates to the technical field of bicycle hubs, in particular to a rolling mechanism for a bicycle hub and a hub manufacturing method.The rolling mechanism comprises a first vertical plate and a second vertical plate which are arranged on the two sides of a base correspondingly; a first U-shaped block is arranged on the inner wall of the first vertical plate and penetrates through a first roller through a rotating shaft; a second U-shaped block is arranged on the inner wall of the second vertical plate, shaft blocks are arranged at the two front ends of the second U-shaped block correspondingly, and the shaft blocks penetrate through second rolling wheels through rotating shafts; the rolling mechanism rolls the pipe fitting into the bicycle hub through the steps of material selecting, discharging, feeding, material penetrating, positioning, rolling forming and discharging, and in the manufacturing process of the hub, material consumption is low, and the machining technology is simple.
