Abstract
A preparation method of shuttle spokes that includes these steps: providing a forging die comprising of an upper die and a lower die with the upper die and lower die having a joint angle of the shuttle spoke structure and an arch radius as well as a gap between the upper die and the lower die; inserting the blank of a round spoke into the gap between the upper die and lower die for stamping; using a plurality of nip molding rollers to eliminate the burr at both ends of the shuttle spoke structure; and applying a plurality of straightening rollers to straightness adjustment of the curved spoke body so that when the wheel parts are rolling, less air vortex can minimize air resistance.

Preparation method of a shuttle shape spoke includes the following steps:
- providing a forging die comprising of an upper die and a lower die having an arch center and meet at a parting gap that passes through center of a forging material for forming a shuttle shape structure;
- inserting a blank of a round spoke into the arch center between the upper die and lower die and stamping the blank spoke into a curved shuttle shape spoke structure;
- removing the curved shuttle shape spoke structure from the forging die and using a plurality of nip molding rollers to eliminate the burr on both sides of the curved shuttle shape spoke structure and to shape the both sides into a cone angle;
- and
- inserting the curved shuttle shape spoke structure into a plurality of angled straightening rollers to adjust the straightness of the curved shuttle shape spoke structure.
