Abstract
A method and a device are provided for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles. The spokes include a spoke shaft having at least two shaft sections. The shaft sections differ in at least one cross-section. For shaping the cross-sections, the wire material is reshaped at least in sections by means of a shaping tool. The relative position of the wire material relative to the shaping tool is varied in the axial direction during reshaping. For shaping the cross-sections in the two shaft sections the relative position of the wire material relative to the shaping tool is varied by way of different positioning movements.
Claims17
A method of manufacturing spokes from a wire material by a reshaping device for at least partially muscle-powered two-wheeled vehicles, the method comprising:
- providing spokes made with the wire material, each of the spokes comprising at least one spoke shaft having at least two shaft sections, wherein the at least two shaft sections differ in at least one cross-section;
- shaping the cross-sections of the at least two shaft sections by forging using a shaping tool of the reshaping device, wherein the shaping tool reduces a diameter of the wire material by a plurality of blows while varying the relative position of the wire material relative to the shaping tool in an axial direction by at least one feeding device of the reshaping device, wherein movement of the wire material relative to the shaping tool during shaping of the cross-sections of the at least two shaft sections is at different speeds;
- and
- adjusting a reduction depth of the shaping tool to adjust the diameter of the wire material using at least one adjustment device of the reshaping device.
