Abstract

A method for the manufacture of steel strip truck rims for wheels of vehicles fitted with tires, by forming the profile of the steel strip ring with variation of the wall thickness, whose flange and groove zones have wall thicknesses greater than the area of the base of the rim subjected to less marked stresses, characterized in that in the first phase of the process, a pre-shaped rim is formed in a drawing operation with a finished or half-finished groove of a strip ring of the corresponding width. This pre-profiled tire then receives, in an extrusion profiling operation, a local reinforcement of the wall in the area that will later constitute the radius of the rim flange, then the area that will form the base of the rim is decreased in its thickness, by means of a known repulsion process itself in the axial direction, and in the fourth phase of the process, the shape of this profiled rim is modified and the definitive profile is given by an extrusion profiling operation.
