【発明の詳細な説明】 本発明は円筒型電池の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a cylindrical battery.
たとえば、第１図に示すような円筒型ニツケル
ーカドミウム電池１は陰陽極板２，３をセパレー

後、電解液を注入し、陽極端子キヤツプ８を付設
した封口蓋９を絶縁パツキング１０を介して外装
缶６の開口部に装着し、ついで外装缶６の開口部
１１の折曲により封口して製造されている。 For example, in a cylindrical Nickel-cadmium battery 1 as shown in FIG. After being inserted into the shaped outer can 6, a seam portion 7 is formed in the outer can. After that, the electrolyte is injected, and the sealing lid 9 with the anode terminal cap 8 attached is attached to the opening of the outer can 6 via the insulating packing 10, and then the opening 11 of the outer can 6 is bent and sealed. Manufactured.
この製造方法においては、渦巻電極体５を外装
缶６に挿入するに際して、円滑に行いうるように
渦巻電極体５の外径を外装缶６の内径より若干小
さくしている。これは渦巻電極体５の挿入時にそ
の外周部が外装缶６の内周面に触れて極板崩れが
生ずることを防止するためである。このため外装
缶６と渦巻電極体５との間に小間隙１２が生ずる
ことになる。 In this manufacturing method, the outer diameter of the spiral electrode body 5 is made slightly smaller than the inner diameter of the outer can 6 so that the spiral electrode body 5 can be inserted smoothly into the outer can 6. This is to prevent the outer circumferential portion of the spiral electrode body 5 from touching the inner circumferential surface of the outer can 6 when the spiral electrode body 5 is inserted, thereby preventing the electrode plate from collapsing. Therefore, a small gap 12 is created between the outer can 6 and the spiral electrode body 5.
ところがこの小間隙１２の存在のために、外装
缶内への挿入後の渦巻電極体は緩みを生じ、陰陽
極板の緊縛度が低下して電池性能に悪影響を生ず

周部にテーピングして緊縛度を保持する方法も考
えられる。しかしこの方法では、小間隙が存在し
たままであるので、リード片１３，１４のちぎれ
等の新たな問題が生ずることになる。 However, due to the existence of this small gap 12, the spiral electrode body becomes loose after being inserted into the outer can, and the tightness of the negative and anode plates decreases, which adversely affects the battery performance. In order to eliminate this inconvenience and to simplify the assembly process, a method may be considered in which the outer periphery of the spiral electrode body is taped to maintain the tightness. However, in this method, since the small gap remains, new problems such as breakage of the lead pieces 13 and 14 arise.
そこで、上述の問題に対処するため、第２図に
示すような方法が考えられる。即ち第２図は円筒
型電池１をダイス１５の透孔１６に貫通させる途

開口部寸法Ｃに縮径されるが縮径時の加工ひずみ
により電池１′の底面１８が下方に彎曲して突出
すると共に電池高さがＤからＥに伸び電池形状及
び電池高さの管理上好ましくない。 Therefore, in order to deal with the above-mentioned problem, a method as shown in FIG. 2 can be considered. That is, FIG. 2 is a state diagram in which the cylindrical battery 1 is being penetrated through the through hole 16 of the die 15, and the battery 1 with the outer diameter dimension A is compressed to the minimum opening dimension C of the die 15 by extrusion with the punch 17. It is something that has a diameter. As shown in FIG. 3, the battery 1 manufactured in this manner is reduced in diameter to the minimum opening dimension C of the die 15, but the bottom surface 18 of the battery 1' is curved downward due to processing strain during diameter reduction. As the battery protrudes, the height of the battery extends from D to E, which is unfavorable in terms of battery shape and battery height management.

を特徴とするものである。 The present invention was devised in view of this point, and is intended to prevent the downward bulge of the bottom surface of the outer can that occurs when a battery is passed through the through hole of a die, and to prevent the bottom surface of the outer can from bulging downward by storing the power generation element. The diameter of the outer can is reduced by passing through holes in a die having a diameter smaller than the diameter of the outer can while supporting the upper and lower ends of the assembled battery in the axial direction with a punch and a holder. That is.
以下本発明の一実施例を図面に基いて説明す

さ寸法Ｄと同じである。 FIG. 4 is a cross-sectional view of the die as the battery passes through it. In this drawing, the battery 1 is assembled as shown in FIG. The battery 1 is passed through the through hole 16 of the die 15 while keeping a constant distance. The insertion opening dimension B of the through hole 16 is the outer diameter A of the battery 1.
The outlet size C of the through hole 16 is smaller than the outer diameter A of the battery 1. Therefore, battery 1 is
6, the battery 1'' has an outer diameter reduced to the discharge port size C, and the bottom surface 18 of the outer can 6 is connected to the receiver 1.
9, it does not bulge downward as shown in FIG. 3, and is substantially flush with the battery as shown in FIG. 5, as shown in FIG. In addition, the height D of the battery 1'' after passing through the through hole 16 is determined by the distance between the punch 17 and the support 19, which are supported by the punch 17 and the support 19 when passing through the through hole 16, and the distance between the punch 17 and the support 19. Since the distance is kept constant, it is the same as the height D of the battery 1 when assembled.

Since the diameter of the outer can is reduced, the downward bulge of the bottom surface of the outer can that occurs when the battery passes through the through hole can be eliminated by the support of the punch and the receiver. Since the battery is passed through the through hole of the die while being supported by the tool, the height of the battery after passing through the hole can be regulated by the distance between the punch holders, which is preferable in terms of battery shape management. becomes.
