Claims20
An apparatus for forming rings on a lead battery terminal including, a head having an outer surface, and a frustum opposite thereto, the apparatus comprising:
- a fixture configured to hold the lead battery terminal;
- a ring forming head configured to form rings on the outer surface of the head of the lead battery terminal when the terminal and ring forming head are rotated relative to each other;
- and
- a drive assembly fastened to the fixture and head to rotate the terminal and ring forming head relative to each other.
A method for forming a ring on a lead battery terminal, the method comprising the steps of:
- providing a lead battery terminal including a head having an outer surface;
- and
- engaging a ring forming head with the outer surface of the head of the lead battery terminal while the ring forming head and the lead battery terminal are rotating relative to each other to form a radial ring on the outer surface of the head of the lead battery terminal.
A method for manufacturing lead battery terminals in a cold forming process, the method comprising the steps of:
- forming an elongated cylindrical lead slug from an extruder lead wire;
- stamping the lead slug in a first forming station forming a partial-finished battery terminal including
- a head having an outer surface,
- a splined ring having a plurality of recesses and tabs, and
- a frustum having a tapered recess and a blank end;
- transferring the partial-finished battery terminal to a second through punch station;
- punching the partial-finished battery terminal in the second through punch station forming a near-finished battery terminal having a through hole;
- transferring the near-finished battery terminal to a third rolling station;
- and
- engaging a ring forming head on the outer surface of the head of the near-finished battery terminal in the third rolling station forming a rolled battery terminal having a head including an annular ring.
A method for manufacturing lead battery terminals in an automated process using a progressive die, the method comprising the steps of:
- transferring a lead slug with a transfer mechanism to a partial-finish station;
- stamping the lead slug in the partial-finish station forming a partial-finished battery terminal including
- a head having an outer surface,
- a splined ring having a plurality of recesses and tabs, and
- a frustum having a tapered recess and a blank end;
- transferring the partial-finished battery terminal to a near-finish station;
- punching the partial-finished battery terminal in the near-finish station forming a near-finished battery terminal having a through hole;
- transferring the near-finished battery terminal to a rolling station;
- and
- engaging a ring forming head on the head of the near-finished battery terminal in the rolling station forming a rolled battery terminal having a head including a ring extending from the outer surface.
