１１１１以上）が必要な場合は、エキスバンド方式や打
抜き方式では製造効率が悪いため、鋳造方式が採用され
ている。Conventional technology Plate grids for lead-acid batteries are manufactured by casting, expanding, punching, etc., but thick plates (approximately 1.5
1111 or higher) is required, a casting method is adopted since the expanding method and punching method have poor manufacturing efficiency.
鋳造方式による極板格子は、所定寸法の極板格子を複数
枚連接させて一体に鋳造しくこれを大板と称する）、ペ
ースト充填後、所定寸法に切断して単位極板（以下、単
板と言う）としている。Plate grids produced using the casting method are made by connecting multiple plates of a predetermined size and casting them into one piece (this is called a large plate), and after filling with paste, they are cut into predetermined dimensions to form unit plates (hereinafter referred to as single plates). ).
一方、極板格子には集電体１１能と、ペースト保持機能

する工程が必要であった。When cutting the thus obtained large board with a circular saw or the like to obtain a veneer, conventionally, as shown in FIG. Therefore, the paste 7a attached to the draft portion of the outer surface of the frame remains. If you assemble a storage battery with this paste remaining, the remaining paste will escape from the electrode grid and become one of the major causes of internal short circuits. A cleaning and residual paste removal step was required.

’程度の抜き勾配（テーパー）が付けられている。In FIGS. 1 and 2, 1 is a plate lattice, 2 is a picture frame forming the outer periphery of the plate lattice, and 3 is a crosspiece that divides the inside of the picture frame vertically and horizontally. In the embodiment, the 14 electrode plate grids are arranged adjacently, 2 horizontally and 7 vertically, within the frame of the step bar (4) for uniformly distributing molten lead to every corner of the grid during casting. 3 between the stay bar and the electrode plate grid, and between the electrode plate grids.
A large board 6 is formed by providing a cutting margin 5 (hatched portion) of approximately m-thickness, and extending and integrating the frame and crosspiece of the lattice. In addition, the frame 2 and crosspiece 3 of the electrode plate lattice 1 are provided with a 6G
It has a draft angle (taper) of about '.
上述の如き形状に鋳造された大板６の空間部には活物質

る。The space of the large plate 6 cast in the above-mentioned shape is filled with active material paste 7, and after drying and chemical conversion process, it is cut at the cutting edge 5 using a circular saw etc. to form a veneer. obtain.
本発明においては、この切断工程において切断シロを隣
接する極板格子の額縁２ａ、 ２ ｂの極板表面側の面
へと抜き勾配面Ｂとの交点Ｃに設定する。In the present invention, in this cutting step, the cutting margin is set at the intersection C with the draft plane B of the frame 2a, 2b of the adjacent electrode plate grid on the surface of the electrode plate surface side.

Fifty storage batteries (150 cells) were assembled and examined for internal short circuits. As a result, there was no occurrence of internal leakage even though no puffing was performed (the presence or absence of internal leakage was determined by a method of dropping the open circuit voltage by leaving it for one week, which allows even the slightest short circuit to be detected).
