Patent ID: 8033153

Claim:
An apparatus for forming rings on a battery terminal, the apparatus comprising: a die station including a plurality of cold forming members moving relative to one another to transform at least a first ring and a second outwardly extending ring on a cylindrical battery terminal body from a first shape to a second shape, the first ring and the second ring each including in both the first shape and in the second shape a first portion a first radial distance from a longitudinal axis of the battery terminal and a second portion a second radial distance from the longitudinal axis, the second radial distance being greater than the first radial distance; wherein in the first shape the first portion of the first ring is spaced a first longitudinal distance from the first portion of the second ring, and the second portion of the first ring is spaced a second longitudinal distance from the second portion of the second ring; wherein in the second shape the first portion of the first ring is spaced a third longitudinal distance from the first portion of the second ring, and the second portion of the first ring is spaced a fourth longitudinal distance from the second portion of the second ring, the second longitudinal distance being greater than the fourth longitudinal distance, and the third longitudinal distance being greater than the fourth longitudinal distance; and a drive apparatus configured to move the at least one cold forming member relative to another cold forming member.
