Abstract
A method and apparatus for cold forming a battery terminal having a base and an insert. The insert includes a first portion encapsulated within the base and a second portion that extends beyond a first side of the base.
Claims26
A cold formed battery terminal comprising:
- a base cold formed from lead;
- and
- an insert having a first portion encapsulated within the base and a second portion extending beyond a first side of the base.
A method for manufacturing a cold formed battery terminal, comprising:
- cold forming a lead slug into a member having a base and a first aperture extending therein;
- placing an insert having a head and longitudinal member into the aperture;
- encapsulating the head within the base.
A method of cold forming a battery terminal, comprising:
- cold forming a lead slug into a first partial terminal including a base having a first side and an opposing second side, and a first aperture extending therein proximate the first side, and a second aperture proximate the second side, the first and second apertures being separated by a first wall;
- removing the first wall in the first partial terminal, forming a first through hole therein;
- placing an insert having a head and an extension member within the first through hole, the head being located within the base, and the extension member extending beyond the base above the first side of the base;
- encapsulating the head within the base by cold forming the partial terminal to substantially close the through hole proximate the second side;
- cold forming the first partial terminal into a second partial terminal including a second extension having at least one acid ring proximate the second side of the base;
- and
- punching a through hole in the recess extending through the base.
4 more elements
A method of seating an insert into a battery terminal, comprising:
- providing a terminal including a recess having a beveled portion with a predetermined diameter;
- providing an insert including a head having a diameter greater than the predetermined diameter of the recess portion;
- and
- forcing the head of the insert within the recess, displacing material within beveled portion of the recess to frictionally engage the head within the recess.
1 more element
An apparatus for cold forming a battery terminal, comprising:
- a first stamping station having a first die configured to cold form a lead slug into a partially formed terminal having a base having a first recess;
- and
- a second stamping station having a second die to cold form the partially formed terminal into a battery terminal including an extension having a second recess.
The apparatus of claim 24 further comprising:
- a ring forming station for forming acid rings having an undercut on the second extension.
