Kind Code:
A1
Abstract:
The present application provides a spoke and a preparation method therefor, and relates to the technical field of spoke manufacturing. The method comprises: performing positive drawing molding and punching on a plate to obtain an arched spoke blank, and forming a pre-hole in the middle of the spoke blank; performing extrusion forming and diameter finishing on the spoke blank to obtain a spoke semi-finished product with a contour surface, the straight edge of the spoke semi-finished product having a preset perpendicularity; punching the spoke semi-finished product to form an air hole and a screw hole bottom hole in the spoke semi-finished product; and finishing the punched spoke semi-finished product, and extruding the screw hole bottom hole to the size to form a screw hole to obtain a spoke finished product. In each process, a composite mold is adopted, and the processing of a plurality of functional features of the product is completed at a time by means of a process, such that the process of the whole manufacturing process is simplified, the input of corresponding device and manpower is reduced, manpower and material resources are saved, the production cost is reduced, and the accumulation error in the product processing process is undoubtedly reduced, such that the processing precision of the product is improved, and the production efficiency and yield are correspondingly improved.
