。Structure of conventional examples and their problems In general, crude lead parts for lead-acid batteries include connectors that physically and electrically connect the electrode plates and connect them to adjacent cells, poles for taking out current, or poles. There are so-called bushings that connect the pillar and the case. These lead parts are
Because lead has a low melting point, it has traditionally been manufactured using gravity casting or pressure forging. Figure 1 shows the gravity casting method, which is a conventional manufacturing method. In the figure, 1 indicates a melting pot for melting lead or a lead alloy, and 2 indicates a mold for casting parts. The lead or lead alloy that has just been melted in the melting pot 1 is poured into a preset mold 2, and after being further cooled by the action of cooling water passing through the mold 2, the mold is opened and cast. Manufacturing of the lead part is completed by separating the lead part from the mold.

な鉛部品を製造することは至難の技であった。For example, this manufacturing method requires a lot of manufacturing time per piece because it repeats a cycle that includes temperature changes of mold setting - pouring - cooling - mold opening - mold release, resulting in a large amount of time loss and low productivity. It was bad. In addition, there are large unstable factors such as the thickness of the mold release agent film and thermal shrinkage in terms of size and shape accuracy, making it extremely difficult to manufacture precision lead parts.

In other words, lead or lead alloy is melted, a continuous rod-shaped material of lead or lead alloy is made using a continuous casting method, this material is divided into lead ingots of the required volume or weight, and then this lead ingot is forged. This is a method of manufacturing lead parts for lead-acid batteries by molding them into a predetermined shape.
