Definitions

  • This invention relates to a product employed for manufacturing weldless metal rims for vehicle wheels, in particular tire rims of aluminium alloy for weldless wheels of motor vehicles,by means of a simplified process.
  • the aluminium alloy tire rims for motor vehicle wheels are presently manufactured starting from a flat plate which is caused to assume the tire rim shape by means of the following operations : cutting from a plate the material cut down size necessary for the tire rim to be obtained; roller leveling said cut down size to assume the shape of an open flat (non-shaped) cylinder; welding the edges of the cylinder so obtained to obtain a not yet shaped tire rim; rolling said tire rim to impart the desired shape to it; final trimming : the resulting tire rim is ready for assembly by welding to the disc-wheel.
  • weldless metal tire rims in particular al- luminium alloy weldless tire rims for vehicle wheels, by means of a simplified process.
  • the manufacturing process consists therefore of the following steps :
  • Particularly - but not exclusively - suited materials to be employed for manufacturing the abovesaid rims and tire rims starting from an extruded pipe are the aluminium alloys of the Al-Mg-Si type of the known Series AA 6000, or the Al-Zn-Mg-Cu alloys of the known Series AA 7000 or the Al-Mg alloys of the known Series AA 5000.
