Abstract
The method for the manufacture of a spoke for spoked wheels including a step of forming a head of the spoke at a longitudinal end of the shank thereof by equipment for the plastic deformation of the end of the shank, wherein the plastic deformation is obtained by maintaining the shank in relative rotation to the equipment.
Claims14
A method for the manufacture of a spoke for spoked wheels including a step of forming a head of said spoke at at least one longitudinal end of the shank thereof, wherein said forming is obtained by means of an equipment for the plastic deformation of the end of the shank, characterised in that said plastic deformation is obtained by maintaining the shaft in rotation with respect to said equipment by maintaining the shank in relative rotation relative to said equipment.
A forming machine for spokes including at least one spoke-forming station and one station for the calibration of the spoke downstream the forming station, wherein said forming station comprises a radial riveting unit driven along a “rosette” path, said forming station comprises a pair of counter-rotating calibrating gauging rollers.
