ものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the improvement of lead-acid batteries, and particularly to the improvement of the electrode plates of batteries for power sources used in agricultural machinery and construction.
従来の技術

ンド方式が開発された。Conventional technology Paste-type electrode plates, which have excellent starting performance, are generally used for automobile batteries. Traditionally, the grid has been made of lead.
Antimony alloy cast gratings have been used. However, in recent years, there has been a strong demand for maintenance-free materials, and lead-calcium alloys have been adopted as new lattice alloys that do not contain antimony, which degrades maintenance characteristics. In addition, a new method for making electrode grids, the extract-kund method, was developed.
この鉛−カルシウム系合金を用いたエキスバンド格子は

己放電が少ないなどメンテナンス・フリー特性にすぐれ
たこの鉛−カルシウム系合金格子は適している。Expanded grids using this lead-calcium alloy are made from rolled sheets. Therefore, by reducing the thickness of the rolled sheet, the grid can be made thinner and lighter, which is industrially superior. Furthermore, since the period of use is limited for batteries for agricultural machinery, etc., this lead-calcium alloy grid is suitable because of its excellent maintenance-free characteristics such as low self-discharge.

られる耐振構造が必要となる。Problems that the invention aims to solveHowever, batteries used for special purposes such as agricultural equipment or construction equipment have special requirements other than those required for automobile batteries, such as maintenance-free characteristics, startability, and light weight and compactness. The key point is improved vibration resistance. In other words, since they are used in extremely uneven areas such as farmland or construction sites, they need a vibration-resistant structure that can withstand harsher conditions than passenger cars.
そこで、本発明は格子の薄形軽量化をはかった状態で耐
振性の向上をはかるものである。Therefore, the present invention aims to improve the vibration resistance while making the grid thinner and lighter.
問題点を解決するための手段
本発明は集電のために設けられている極板の耳部が、湾
曲した状態で群溶接したものであり、振動による極板の
切れを防ぐ耐振構造を達成するものである。Means for Solving the Problems In the present invention, the ears of the electrode plate provided for current collection are group welded in a curved state, thereby achieving a vibration-resistant structure that prevents the electrode plate from breaking due to vibration. It is something to do.
作 用
このように構成することで、農機具、建設用王様のだめ
のバッテリーの耐振性を高めるものである。Function: By configuring it in this way, the vibration resistance of the battery for agricultural machinery and construction equipment is improved.
メンテナンス・フリータイプの鉛−カルシウム系エキス
バンド格子は圧延シートを薄くして、従来の鋳造式格子
よシも薄くつくられ、軽量化がはかられている。しかし
、エキスバンド格子はエキスバンド加工された骨の厚み
よりも、集電用の耳部はシートの厚みと同じ厚さで薄く
なっている。Maintenance-free lead-calcium expanded grids are made from thin rolled sheets, making conventional cast grids thinner and lighter. However, the expanded lattice is thinner than the expanded bone, and the current collecting ears are thinner, with the same thickness as the sheet.
したがって、振動試験を行なった場合、群溶接の棚から
耳部が切れて極板が脱落することが耐振性を弱くしてい
る原因であった。しかも、比較的垂直方向の振動には強
いが、横方向の振動が加わったときにとくに極板が脱落
しやすいことがわかった。Therefore, when a vibration test was conducted, the ear part was cut off from the group weld shelf and the electrode plate fell off, which weakened the vibration resistance. Moreover, although it is relatively resistant to vertical vibrations, it was found that the electrode plates are particularly susceptible to falling off when lateral vibrations are applied.
そこで、本発明では耳部を湾曲させて群溶接することに
より、横方向に対する振動に強くなり、耐振性を大幅に
向上させたものである。Therefore, in the present invention, the ears are curved and welded in groups, thereby making it strong against vibrations in the lateral direction and greatly improving vibration resistance.
なお、湾曲させることで耳部自身も強固になり、棚との
溶着強度も増加すると考えられる。It is thought that by curving the ears, the ears themselves become stronger and the strength of the weld to the shelf increases.
実施例 つぎに実施例で、本発明を説明する。Example Next, the present invention will be explained with reference to Examples.
鉛−カルシウム合金製の圧延シートを用いてエキスバン
ド加工し、連続したエキスバンド格子をつくった。A continuous expanded lattice was created by expanding the rolled sheet of lead-calcium alloy.
この連続したエキスバンド格子にペーストを塗着して第
１図に示す極板１をつくった。A paste was applied to this continuous expanded grid to produce the electrode plate 1 shown in FIG. 1.
なお極板１はペーストを塗着した直後の帯状の長へ格子
を、ロータリーカッターで所定の寸法に切断した。この
ときカッターの刃の角度とロールの径により、切断され
た極板は湾曲状態になる。Note that the electrode plate 1 was obtained by cutting the grid into a strip-like length immediately after applying the paste to a predetermined size using a rotary cutter. At this time, the cut electrode plate becomes curved depending on the angle of the cutter blade and the diameter of the roll.
とくに耳部２は刃の中へ押し込まれるようにして切断さ
れるので、ロール面の円径にそって湾曲する。In particular, since the ears 2 are cut by being pushed into the blade, they are curved along the diameter of the roll surface.
ペーストを塗着した面は耳部よりも厚くして、ロータリ
ーカッターで切断した後、フラットローラーを通過させ
、ペーストを塗着した面は平面とし、耳部２は切断した
ときの湾曲がそのまま残るようにした。The surface to which the paste is applied is made thicker than the ears, and after cutting with a rotary cutter, it is passed through a flat roller, so that the surface to which the paste is applied is flat, and the edge 2 remains curved as it was when it was cut. I did it like that.
このようにして得られた極板を用い、本発明の電池Ａを
構成した。Battery A of the present invention was constructed using the electrode plate thus obtained.
比較例としてレシプロ式で極板を切断し、耳部も湾曲の
ない状態につくられた極板を用いて電池Ｂをつくった。As a comparative example, a battery B was made using a plate that was cut using a reciprocating method and whose ears were not curved.
この電池Ａ、Ｂを用いて振動試験を行なった。A vibration test was conducted using these batteries A and B.
第２図にその結果を示す。図から明らかなように本発明
の電池Ａは、比較例Ｂよりも耐振性にすぐれている。と
くに本発明の電池は４Ｇ以下の振動では極板の切断がな
かった。これは、振動の多い用途に適した構造であるこ
とを示している。Figure 2 shows the results. As is clear from the figure, Battery A of the present invention has better vibration resistance than Comparative Example B. In particular, in the battery of the present invention, the electrode plate did not break under vibrations of 4G or less. This shows that the structure is suitable for applications with a lot of vibration.
尚、群溶接において、本発明のように耳部が湾曲してい
ると足し鉛が流れ落ちやすくなるので、溶接条件の設定
は難しくなる。そこで簡単な方法として耳部を溶融鉛中
に浸漬するキャストン方式を採用するとよい。しかし、
本発明はその方式を制限するものではなく、溶接で若干
のだれ鉛が発生しても本発明の効果は同じである。In group welding, if the ears are curved as in the present invention, additional lead tends to flow down, making it difficult to set welding conditions. Therefore, as a simple method, it is recommended to adopt the Caston method in which the ears are immersed in molten lead. but,
The present invention does not limit the method, and the effect of the present invention is the same even if some lead dripping occurs during welding.
