の歯型で切り込みながら同時に押し拡げて小さなダイヤ
状の桝目を形成するものである。Conventional technology The casting method, punching method, or expanded band method has been used to manufacture grids for lead-acid batteries, but in recent years, the expanded method has been increasingly used because it is easy to apply to calcium alloys, which have difficulty in casting. There is. In this method, slits are provided in the sheet and the sheet is stretched out, or V-shaped teeth are used to make cuts and the sheet is simultaneously pushed and expanded to form small diamond-shaped cells.

口で枠骨の無い桝目ができることが、変形に対する弱点
を産む原因となっている。Problems to be Solved by the Invention Generally speaking, this construction method is prone to deformation due to the mechanical tension applied to it, but in particular the mesh-shaped structure, which is an aggregate of X-shaped bones, is susceptible to deformation. Since a unit plate shape that is approximately rectangular is cut out from the body, a square without a frame bone is created at one of the cuts, which creates a weakness against deformation.
本発明はこの変形しやすい構造に対して、とくに極板の
上下左右方向の強度を改善することを目的とする。本発
明者らは別途上記の目的に対し従来の技術で一旦多孔体
加工により網状化された連続体に絞り加工を加える新し
い製造法を提供した。The purpose of the present invention is to improve the strength of the electrode plate in the vertical and horizontal directions, particularly for this easily deformable structure. Separately, the present inventors have provided a new manufacturing method for the above-mentioned purpose in which a continuous body that has been made into a mesh by porous body processing is subjected to a drawing process using conventional techniques.
すなわち従来技術で得られた網状体の骨格を一部扁平状
に圧延絞りするとともに、平坦化されるこの面に任意の
形状の突部を同時に絞シ成形するものである。That is, a part of the skeleton of the net-like body obtained by the prior art is rolled and drawn into a flat shape, and at the same time, a protrusion of an arbitrary shape is formed on this flattened surface by drawing.
本発明はこの絞りローラの具体的で新規な形状を提供す

を形成することを特徴とする。A means to solve the problem, that is, the lattice manufacturing apparatus of the present invention is to reduce the size in the thickness direction of the skeleton previously formed on the roller of the drawing device following the porous body forming device such as the expand processing device. It is also characterized by having a surface for thinning the bone and forming a concave pattern of arbitrary depth within that surface.
作 用
すなわちこの基本構成により、もともと変形させてつく
られるような変形に対して弱い構造の骨格に対してこれ
を扁平化し、平面方向のいずれの方向にも強度を改善す
るとともに、扁平化された面上に各種パターンの突部を
形成して活物質の保持性を改善することができる。This basic structure flattens the structure of the skeleton, which is originally weak against deformation and improves its strength in any direction in the plane. The retention of the active material can be improved by forming protrusions in various patterns on the surface.
実施例 以下、本発明を実施例で詳述する。Example Hereinafter, the present invention will be explained in detail with reference to Examples.
第１図は本発明の絞りローラ部の断面図であ久１は従来
の多孔体形成装置で形成された網状多孔体骨格２をその
加工時の厚さよりも扁平にする面であり、３はその面に
設けられた突部形成用の凹部である。FIG. 1 is a cross-sectional view of the squeezing roller section of the present invention. 1 is a surface that makes the mesh porous body skeleton 2 formed by a conventional porous body forming apparatus flatter than the thickness at the time of processing, and 3 This is a recess for forming a protrusion provided on the surface.
本例では対をなす上下の各ローラに対応した凹部パター
ンを設けているが、片側のローラだけに凹部パターンを
設けてもよい。In this example, a recess pattern is provided corresponding to each of the upper and lower rollers forming a pair, but the recess pattern may be provided only on one roller.
また骨の部分が絞られる時、ダイヤ状桝目の空間側４に
絞り出される寸法を規制するように第２図のように上下
ローラの密着部５を設けても良いが、実際に鉛合金の場
合は、任意に展開するＫまかせていく方が効率が良い。In addition, when the bone part is squeezed, a close contact part 5 of the upper and lower rollers may be provided as shown in Fig. 2 to restrict the size squeezed out to the space side 4 of the diamond-shaped square, but in reality, lead alloy In this case, it is more efficient to leave it to K to develop arbitrarily.
第３図Ａ、Ｂはローラ上に従来の鋳造格子と類似した格
子縞構造の突部形成用の溝７を設けた例を示す。この構
造では絞り加工前の網状体がエキスバンド加工によるダ
イヤ状桝目をもつものであるとき、矩形とは当然一致し
ない。しかじなか・ら、Ｘ字型の扁平網状骨の各所で第
４図に示すような突部の絞りパターンができる。したが
って、必ずしも最終にでき上るＸ字型の扁平パターンに
無理に合致させて絞り突部用の凹部パターンを形成する
必要はない。当然斜線、円型などのパターンを組み合せ
た設計も可能である。FIGS. 3A and 3B show an example in which grooves 7 for forming projections having a checkered structure similar to a conventional cast grid are provided on the roller. In this structure, when the net-like body before drawing has diamond-shaped cells formed by expanded band processing, it naturally does not match the rectangular shape. From the inside, a constricted pattern of protrusions as shown in Fig. 4 is formed at various places on the X-shaped squamous cancellous bone. Therefore, it is not necessarily necessary to form the concave pattern for the aperture protrusion by forcibly matching the X-shaped flat pattern that will be finally formed. Naturally, a design combining patterns such as diagonal lines and circles is also possible.
また上下のローラにおいて突部形成用凹部のパターンは
必ずしも一致させる必要は無い。むしろ上下の絞り部に
設ける凹部は若干ずれる方が望ましい。その理由は平滑
部で絞り出された鉛合金の凹部に流れ込む量が不足する
場合がちり、目的の絞り突部を形成できないことがあり
、凹部を上下のローラに形成する位置を若干ずらすと、
これを助けることができる。Furthermore, the patterns of the concave portions for forming protrusions on the upper and lower rollers do not necessarily have to match. Rather, it is preferable that the concave portions provided in the upper and lower aperture portions be slightly shifted. The reason for this is that sometimes the amount of lead alloy squeezed out on the smooth part flows into the recesses is insufficient, making it impossible to form the desired squeezed protrusions.
You can help with this.
エキスバンドのパターンを絞り加工すれば、原則として
扁平のＸ字型パターンになる。この時の絞り突部の形状
をあらかじめＸ字型パターンに合せて凹部を形成してお
くと、扁平Ｘ字型パターンは一層強度の向上改善がなさ
れる。If the extended band pattern is drawn, it will basically become a flat X-shaped pattern. At this time, if the concave portion is formed in advance so that the shape of the aperture protrusion matches the X-shaped pattern, the strength of the flat X-shaped pattern can be further improved.
この時の凹部パターンは、最終圧延される骨格部の扁平
骨の幅のピッチ以下で設計することにより、骨格の位置
が多少ずれても、必ず扁平骨格の上に突部の芯が連続的
にできるので、補強や導電性には好都合である。At this time, the recess pattern is designed to have a pitch equal to or less than the width of the flat bones of the skeleton to be finally rolled, so that even if the position of the skeleton is slightly shifted, the core of the protrusion will be continuous on top of the flat skeleton. This is advantageous for reinforcement and conductivity.

るものである。Effects of the Invention As described above, the present invention provides a new lattice manufacturing device for further drawing a porous net-like body, particularly an appropriate configuration of the drawing roller, all of which are different from conventional modifications. By flattening the lattice structure, which has a weak point against the surface, the deformation in the horizontal direction with respect to a flat surface is significantly improved, and the protrusions formed by the recesses increase the bonding area with the active material, and these protrusions This strengthens the structure and improves the retention of active materials.
