ABSTRACT:
A method and apparatus to cold form an L-shaped lead battery terminal. The apparatus includes a forming station for cold forming an L-shaped lead battery terminal having a tower offset from the head. The forming station includes a split die for forming a head having a radial ring. The apparatus also includes a punching station for forming a continuous through hole in the head and a recess in the tower. Another method and apparatus to cold form an L-shaped lead battery terminal includes a forming station, punching station and a rolling station for forming a ring on the terminal. The forming station includes a unitary die to form a head having a uniform diameter and a tower offset from the head. The rolling station includes a fixture, a rolling head having a plurality of rollers, and a drive system for engaging and rotating the rolling head and lead battery terminal relative to each other.
