Abstract

Procedimento di rullatura per la realizzazione di una puleggia (1) provvista di una pluralità di gole (6) periferiche a V, in cui un semilavorato circolare viene sottoposto a fasi successive di deformazione plastica eseguite mediante attrezzi (20) provvisti ciascuno di una coppia di rulli (22, 23) operanti contemporaneamente su una stessa porzione periferica del semilavorato stesso e di una forcella (21) oscillante supportante i rulli (22, 23).(Figura 3).Rolling process for the realization of a pulley (1) provided with a plurality of peripheral V-shaped grooves (6), in which a circular semi-finished product is subjected to successive phases of plastic deformation performed by tools (20) each provided with a pair of rollers (22, 23) operating simultaneously on the same peripheral portion of the semi-finished product itself and of an oscillating fork (21) supporting the rollers (22, 23). (Figure 3).
