Abstract:

The present invention provides a novel method for manufacturing a vehicle wheel with a single work piece or band 101. The method comprising the steps of placing a metal band 101 in a mandrel 102 provided at a machining tool; forming the metal band/work piece 101 for making a desired length of rim 201 and a wheel disc 202; spinning a nave portion 401 of the work piece 101 for shaping the wheel disc 202; spinning the work piece 101 for making a disc flange 502 and a gutter portion 504 of the wheel; rolling one end of the rim portion to form the required gutter portion 504 of predetermined shape and thickness; spinning the rim portion further to form a tyre seat and well area 701; forming a flange flare 801 by bending another end of the rim portion; forming the flange portion 901 of the wheel rim by bending the flange flare 801; machining flange edge 1201, nave 1202 and bore; reaming of bolt holes and chamfering bores at the wheel disk portion.
