Abstract
The invention relates to a method for molding the positioning structure of a bicycle hub. The bicycle hub positioning structure comprises a hub shell and a storage portion formed at two ends of the hub shell. The outer wall of the hub shell is clamped and positioned by a positioning device. The inner wall of the storage portion is stamp-molded by a stamping press in the axial direction to form at least three positioning mechanisms. The structure is implemented by the following steps: A. bicycle hub clamping step, B. bicycle hub stamping step, and C. bicycle hub loading step. The bicycle hub positioning structure is adaptive to the rapid stamping molding without changing the strength thereof.
