FIELD: physics.
SUBSTANCE: method of making a lead terminal for an accumulator through plastic deformation on a cold working device, which has a moulding machine and at least one deformation device (30, 40, 50, 60, 80), by moulding a workpiece (7) on the said moulding machine, where the workpiece stretches along the longitudinal axis so to provide for the main (9) and contact (8) part of this terminal, and size which is comparable to size of the terminal being made; taking the workpiece (7) to the deformation device (30, 40, 50, 60, 80); carrying out the first deformation of the workpiece (7) for internal and external moulding of its main part (9); and second deformation of the workpiece (7) for at least further internal and external moulding of the main part (9), where these deformation operations are carried out successively as stages for gradual deformation.
EFFECT: high quality of manufacturing.
