本発明は鉛蓄電池用エキスパンド基体の端部処
理法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating the ends of expanded substrates for lead-acid batteries.
従来鉛蓄電池用エキスパンド基体は、鉛あるい
は鉛合金シートにラス状にするためのエキスパン

である。即ち、基体の端部は鋸歯状であり、従つ
て、該基体の端部の活物質保持能力は、他の部分
に比べて小さく、該部分に充填された活物質は非
常に脱落し易いという欠点を有していた。 Conventional expanded substrates for lead-acid batteries are simply made by expanding a lead or lead alloy sheet into a lath shape and then cutting the sheet into predetermined dimensions. That is, the edges of the substrate are serrated, and therefore the active material retention capacity of the edges of the substrate is smaller than that of other parts, and the active material filled in these areas is very likely to fall off. It had drawbacks.
本発明は上記の如き欠点を除去するものにし

のである。 The present invention eliminates the above-mentioned drawbacks, and utilizes the flexibility of lead or lead alloy to form the serrated end of the base body into squares constituting the serrated end. By forcing the protrusions of the pentagonal pyramids aligned in a straight line and processing them into a straight line, it is possible to prevent the active material filled at the ends from falling off.
本発明の一実施例を説明する。 An embodiment of the present invention will be described.

の変形加工を行う。 A sheet 3 made of lead or lead alloy fed from a lead or lead alloy sheet stock roll 2 by a feed roller 1 is expanded into a lath shape by an expander 4. The lath-shaped sheet 3' is sent to a device 5 by a feed roller 1'. The device 5 cuts the lath-shaped sheet 3' into a predetermined size and simultaneously deforms the cut portion.
次に装置５の構造および機能について説明す
る。 Next, the structure and function of the device 5 will be explained.
装置５は固定部６と可動部７からなつている。

るものである。 The device 5 consists of a fixed part 6 and a movable part 7.
The protrusions 9, 9' lined up along the laths on both sides of the cutter 8 for cutting the lath-processed sheet 3' into a predetermined size deform the serrated edges after cutting. That is, the protrusion 9 is deformed into a straight line as shown in FIG. 2 by pushing the sawtooth end after cutting into the squares that make up the end. It forms a pentagonal pyramid with the serrated ends aligned in a straight line. Further, the protruding portion 9' is a square pyramid having a bottom surface that is the same as the shape of the lath, and is pushed into the lath that does not form the end portion to prevent the lath from being deformed.
第４図におけるＢは、第４図において一点鎖線
で示した切断部を矢印の方向から見たときの断面
図およびそれに対する固定側を示すものであり、
動作原理を説明する。 B in FIG. 4 is a cross-sectional view of the cut portion indicated by the dashed dotted line in FIG. 4 when viewed from the direction of the arrow, and the fixed side thereof;
The operating principle will be explained.
まず、可動側は途中まで下降した状態即ち、突
出部９による変形動作に入る直前の状態において
ラス状に加工されたシート３′を固定する。次に

端部を構成するラス目に押入されて切断後の鋸歯
状端部の変形加工を行なうと同時に突出部９′は
鋸歯状端部を構成しないラス目に押入されて該ラ
ス目の変形が防止される。 First, the movable side fixes the lath-shaped sheet 3' in a state where it has been lowered halfway, that is, in a state immediately before the deformation operation by the protruding portion 9 begins. Next, the cutter 8 descends to cut the sheet 3' of a predetermined size, and after cutting, the cutter 8 returns to its original position, and the movable side descends until it touches the sheet 3', and the protrusion 9 forms a serrated edge. The protrusion 9' is pushed into the lath to deform the serrated end after cutting, and at the same time, the protrusion 9' is pushed into the lath which does not constitute the serrated end to prevent deformation of the lath.
かくして、第１図に示すエキスパンド基体１０
の鋸歯状の端部１１は、第２図に示す如き直線上
の端部１２に加工される。 Thus, the expanded substrate 10 shown in FIG.
The serrated end portion 11 is processed into a straight end portion 12 as shown in FIG.

ある。 As described above, the present invention completely eliminates the phenomenon of active material falling off at the edges of an expanded substrate, and can reduce the number of steps compared to conventional edge treatment methods using resins such as polyvinyl chloride and polyethylene. Its industrial value is enormous.
