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.
Claims21
A method of manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles, comprising:
- providing spokes, each comprising at least one spoke shaft having at least two shaft sections, wherein the shaft sections differ in at least one cross-section;
- shaping the cross-sections so that the wire material is reshaped at least in sections by means of a shaping tool;
- varying the relative position of the wire material relative to the shaping tool in the axial direction during shaping;
- and in the shaping of the cross-sections in the at least two shaft sections the relative position of the wire relative to the shaping tool is varied using different positioning movements.
A device for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles, the spokes each having at least one spoke shaft having at least two shaft sections, wherein the shaft sections differ in at least one cross-section, comprising:
- at least one reshaping device which is suitable and configured to reshape the wire material at least in sections by means of at least one shaping tool for shaping the cross-sections;
- and the relative position of the wire material relative to the shaping tool is varied in the axial direction during shaping by at least one feeding device;
- and the feeding device is suitable and configured to vary the relative position of the wire material relative to the shaping tool by different positioning movements for shaping the cross-sections of the at least two shaft sections.
