  • Method of making battery terminal with necked flange
    Patent number: 5373720
    Abstract: A cold-forming method of making a finished battery terminal with a necked down flange by first expanding the metal radially outward until the battery terminal die cavity is partially filled with metal and then upsetting the metal to complete the deformation filling of the battery, terminal die cavity and to simultaneously form a necked down region in the flange on the battery terminal.

  • Method of making a high torque battery terminal
    Patent number: 5349840
    Abstract: A battery terminal with high torque resistance utilizing three sided frusto-conical recesses and mating protrusions extending from the battery terminal and method of making the terminal by a cold forming process that forms a finished battery terminal from a preworked lead slug by driving one end of a punch through the slug to remove excess material and form an axial through hole, a second and third portion of the punch to close the die chamber and a fourth portion of the punch to radially expand the lead slug into a finished battery terminal. The dies for forming the battery terminal include a movable multiple-segmented die for collapsing radially inward around the slug and a frusto-conical die for forming the top portion of the battery terminal. An ejector sleeve removes the finished battery terminal after the cold forming process.
