Abstract
Abstract An automated apparatus for sequentially forming integrally fused battery terminals on a plurality of storage batteries is described wherein a head means having a mold means adjustably mounted thereon is automatically movable with respect to a vertical axis, and has slidably mounted thereon a burning means for automatically producing a variable intensity flame for melting said battery elements to form said integrally fused battery terminal during a vertical stroke thereof. A novel molding means is described comprising a structural member composed of aluminum or other high heat transfer material, which is adapted to interchangeably engage an aluminum mold member which mates with a structural housing and which actually forms the voids in which the melting and casting processes take place. The mold members, which are also composed of aluminum or other high heat transfer material, are provided with a novel mold coating consisting essentially of aluminum oxide formed through a hard surface anodizing process. This novel mold coating is disposed on the surfaces of the mold members which define molding voids, and act as a thermal barrier to cause momentary delay of heat transfer from the melted terminal posts to the remainder of the mold members and their associated structural housings. This novel mold coating is described as having superior release characteristics, while facilitating the formation of high quality battery terminal posts. Novel means are provided wherein the mold member and structural member are complementally conformed to ensure inter-engagement in the operating position facilitating excellent heat transfer to the cooling medium. A novel thermocouple means is mounted on a structural member, the tip of which is embedded within a protrusion formed on the mold member, which thermocouple means and its associated logic cooperate with the operational logic to ensure that uniform high quality terminals are consistently produced.
