Abstract:
Process for producing a commutator for electrical machinery having a formation with a plurality of projecting segments disposed around an insulating material and insulated relative to one another by the insulating material and with a plurality of connection elements, each of which project radially from a respective one of the projecting segments, comprising the steps of:shaping the connection elements, with a finished outline and size, and with a ductile finished state, directly from essentially unmachined raw conductive material by material displacement by forming an initial blank of said conductive material having a disc shape with an circular peripheral wall, and by deforming the initial blank to deform material radially outward of said peripheral wall, thereby creating said connection elements radially projecting on the peripheral wall of the blank; andcold forming the blank with the radially projecting connection elements from its disc shape into a pot-shaped blank with an essentially cylindrical jacket and an essentially flat bottom.
