A method of manufacturing a lead terminal for an accumulator by plastic deformation on a cold-working apparatus i that has a shaping station (2) and at least one deformation station (30, 40, 50, 60, 80) by shaping, at the shaping station, a slug (7) that has a longitudinal extension along a longitudinal axis such as to provide base (9) and contact (8) parts for the terminal and a I size commensurate with the size of the terminal end piece to be manufactured; transferring the slug (7) to the deformation station (30, 40, 50, 60, 80); carrying out a first deformation of the slug (7) for inner and outer shaping of its base part (9); and carrying out a second deformation of the slug (7) for performing at least a further inner and outer shaping of the base part (9). The deformations being performed sequentially as progressive deformation steps. |
