In the above, the lead pole component, the lead component and the ear are used in a state where the lead pole-equipped lead component having lead as a main component and having the ear insertion hole portion is fitted into the ear portion.

Is. Then, the ear insertion hole 2 of the lead component 1 is inserted into the electrode ear 9 and the ear insertion hole 2 and the ear 9 are fitted to each other and heated together with the pole column component 18 for welding. Thus, the pole 8 and the strap 6 are integrally formed.

以下において、本発明に係わる一実施例について図１〜３を用いて詳細に説明する。
１．鉛部品1の作製
本発明では、図１に示されるような耳挿入穴部2を有する鉛部品1を、ブックモールド方式で鋳造して用いることを特徴としている。すなわち、約２００℃に加熱した、掘り込みのある２枚の鉄鋼製の鋳型を対向させた状態で、鉛を主成分とする合金の溶湯を注ぎ込み、凝固させ、離型して図１に示されるような鉛部品1を作製した。 Hereinafter, an embodiment according to the present invention will be described in detail with reference to FIGS.
1. Production of Lead Component 1 The present invention is characterized in that a lead component 1 having an ear insertion hole 2 as shown in FIG. 1 is cast and used by a book mold method. That is, in a state where two steel molds that have been dug and heated to about 200 ° C. face each other, a molten alloy of lead-based alloy is poured, solidified, and released, as shown in FIG. A lead component 1 as shown in FIG.

耳挿入穴部2は、図２及び図３に示されるように電極板の耳部9と嵌合される部分である。さらに、図１に示されるように、鉛部品1の厚み方向の略中央部分には、外側方向に向けて凸状をした突部11を設けるようにした。すなわち、耳挿入穴部2の表面部分の面積が、中央部分の面積よりも大きくなるようにした。ここで、鉛部品1の厚み方向の略中央部分に突部11を設けることによって、鋳型からの離型が容易になるとともに、耳挿入穴部2に電極板の耳部9を挿入しやすくすることができる。
２．溶接
本発明に係わるストラップ6及び極柱8の形成方法について図２、３を用いて詳細に説明する。
図３に示されるように、従来の手法で複数枚の電極板（正極板、負極板）をセパレータを介して積層をした後に、それぞれ電極板の耳部9に櫛歯12を挟み込む。そして、櫛歯12には鉛を主成分とする極柱部品18を置き、平板状をした耳部9には上方から本発明に係わる鉛部品1を嵌合させる（図３（ａ））。 The ear insertion hole portion 2 is a portion to be fitted with the ear portion 9 of the electrode plate as shown in FIGS. Furthermore, as shown in FIG. 1, a protrusion 11 that is convex toward the outer side is provided at a substantially central portion in the thickness direction of the lead component 1. That is, the area of the surface portion of the ear insertion hole 2 was made larger than the area of the central portion. Here, by providing the protrusion 11 at the substantially central portion of the lead component 1 in the thickness direction, the mold can be easily released from the mold, and the ear portion 9 of the electrode plate can be easily inserted into the ear insertion hole portion 2. be able to.
2. Welding A method for forming the strap 6 and the pole column 8 according to the present invention will be described in detail with reference to FIGS.
As shown in FIG. 3, after laminating a plurality of electrode plates (positive electrode plate, negative electrode plate) via a separator by a conventional method, comb teeth 12 are sandwiched between the ear portions 9 of the electrode plates, respectively. Then, a pole pole component 18 containing lead as a main component is placed on the comb teeth 12, and the lead component 1 according to the present invention is fitted to the tab-shaped ear portion 9 from above (FIG. 3A).

そして、極柱部品8、耳部9及び鉛部品1をバーナ3やＴｉｇなどによって上方から加熱して溶解させる（図３（ｂ））。ここで、図３（ｂ）に示すように、例えばバーナ3を用いて、極柱部品18、耳部9及び鉛部品1の嵌合部分を加熱して、これらを溶接するようにした。   Then, the pole column component 8, the ear portion 9, and the lead component 1 are heated and melted from above with a burner 3 or Tig (FIG. 3B). Here, as shown in FIG. 3B, for example, the burner 3 is used to heat the fitting portions of the pole column component 18, the ear portion 9, and the lead component 1 and weld them.

そして、バーナ3を遠ざけて溶接部を冷却して凝固させた後に、耳部9に挟み込んだ櫛歯12を取り外すことによって、極柱8を有するストラップ6が形成されるようにした（図３（ｃ））。   Then, after the burner 3 is moved away and the welded portion is cooled and solidified, the comb teeth 12 sandwiched between the ear portions 9 are removed to form the strap 6 having the pole column 8 (FIG. 3 ( c)).

ここで、図１に示されるように、鉛部品1の厚み方向の略中央部分には、耳挿入穴部2に向けて外側に凸状をした突部11を設けると、耳部9や鉛部品1の溶解がスムーズになり、短時間で嵌合部分を溶接できることがわかった。すなわち、本発明に係わる鉛部品1を用いると、溶接時の作業性を向上させることができる。加えて、詳細なデータは示されていないが、本発明に係わる鉛部品1を用いると、ほぼ一定の速度でバーナ3を移動させるような比較的単純な手法を用いても、厚みのバラツキが少ないストラップ6を形成することができた。   Here, as shown in FIG. 1, when a protruding portion 11 that protrudes outward toward the ear insertion hole 2 is provided at a substantially central portion in the thickness direction of the lead component 1, the ear 9 and lead It was found that the melting of the part 1 was smooth and the fitting part could be welded in a short time. That is, when the lead component 1 according to the present invention is used, workability during welding can be improved. In addition, although detailed data is not shown, when the lead component 1 according to the present invention is used, even if a relatively simple method such as moving the burner 3 at a substantially constant speed is used, there is no variation in thickness. Fewer straps 6 could be formed.

なお、ストラップ6の厚みのバラツキが少ない詳細は不明ではあるが、鉛部品1と耳部9との間に、すきま14が形成されていることによって、この部分が加熱しやすくなるとともに、溶解した鉛合金が重力によって、自然にすきま14の部分に流れ込むためと考えられる（図２（ｂ））。   Although the details of the variation in the thickness of the strap 6 are not clear, the gap 14 is formed between the lead component 1 and the ear portion 9, so that this portion is easily heated and melted. This is because the lead alloy naturally flows into the gap 14 due to gravity (FIG. 2B).

さらに、図２（ｃ）に示されるように、耳部9と鉛部品1との嵌合部分のうちで、バーナ3による加熱時間や加熱熱量を調整することによって、鉛部品1の突部11よりも上方の部分のみを溶接することもできる。そして、図２（ｃ）に示されるような溶接をすると、図５に示すような制御弁式鉛特電池を作製して長期間の運転をした場合でも、耳部9と鉛部品1との界面での腐食が少なくなることが分かった。この詳細な理由については不明であるが、この溶接方式は、大電流での放電が要求されない用途の鉛蓄電池に用いることができる。   Further, as shown in FIG. 2C, the protrusion 11 of the lead component 1 is adjusted by adjusting the heating time and the amount of heat by the burner 3 in the fitting portion between the ear portion 9 and the lead component 1. It is also possible to weld only the upper part. Then, when welding as shown in FIG. 2 (c) is performed, even if a control valve type lead special battery as shown in FIG. It has been found that corrosion at the interface is reduced. Although this detailed reason is unknown, this welding method can be used for a lead-acid battery for applications that do not require discharging at a large current.

加えて、鋳造時において、図６に示されるような、鉛部品1と極柱部品18とを合体させた構造の極柱付鉛部品19を用いることによって、櫛歯12にセットする際の工程を省くことができる。また、これらが合体されているために、図３の場合のように、鉛部品1と極柱部品18との溶接状態に特別の注意を払う必要がない。したがって、耳部9との溶接をしやすくすることができる（図６（ａ））。なお、詳細な説明は省略したが、極柱付鉛部品19の耳挿入部2の形状等は上記した図１に示すようになっており、この場合の溶接工程も上述した図２とほぼ同様に行うことができる。   In addition, at the time of casting, as shown in FIG. 6, a process for setting the comb teeth 12 by using the lead pole-attached lead part 19 having a structure in which the lead part 1 and the pole pole part 18 are combined. Can be omitted. Moreover, since these are united, it is not necessary to pay special attention to the welding state of the lead component 1 and the pole column component 18 as in the case of FIG. Therefore, welding with the ear | edge part 9 can be made easy (FIG. 6 (a)). Although the detailed description is omitted, the shape and the like of the ear insertion part 2 of the lead part 19 with pole poles are as shown in FIG. 1, and the welding process in this case is almost the same as that in FIG. Can be done.

上述した実施例では、本発明を制御弁式鉛蓄電池に用いた場合について示したが、自動車用バッテリなどの液式の鉛蓄電池にも同様に用いることができる。   In the above-described embodiments, the case where the present invention is used for a control valve type lead storage battery has been described. However, the present invention can be similarly used for a liquid type lead storage battery such as an automobile battery.
