・オン・ストラップ方式が採用されている。2. Description of the Related Art In recent years, as for a lead-acid battery electrode plate, as a manufacturing method of forming a strap or a pole in the ear part of the electrode plate group, the ear part of the electrode plate group is inverted and inserted into a mold provided with a recessed portion, Inject the lead melt made of lead alloy into the mold, or immerse the electrode group ear in the mold in which the lead melt has been injected in advance, and attach the ear of the electrode group to the strap or pole. The cast-on-strap method that welds together is adopted.

の耳部の溶接性が劣る欠点を有していた。Problems to be Solved by the Invention In the above-mentioned manufacturing method by the cast-on-strap method, the ears of the electrode plate group are welded with a limited amount of heat due to a certain amount of lead molten metal forming the straps or poles. is there. Therefore, if the ears of the electrode plates are immersed in lead molten metal after the surface of the ears of the positive and negative electrode plates that are easily assembled into an electrode plate group are subjected to brushing, etc. Since the amount of heat transfer in the part is large, only the cut surfaces of the ears of the positive and negative plates, which are cut to a certain height, are welded.
In order to improve this, a method of thinning the entire ear part of the electrode plate of the strap forming part or applying a rosin-based flux to the ear part of the electrode plate has been adopted. There was a problem that strength and corrosion resistance were reduced. In this way, the cast-on-strap method is more complicated than the manufacturing method by welding the pre-cast lead alloy pole column and the ears of the electrode plate group using the oxygen-hydrogen gas burner, and the ear of the electrode plate is more complicated. The weldability of the part was inferior.
本発明は、上記欠点の除去を目的とするものである。The present invention aims to eliminate the above drawbacks.

る。Action As a result, the cross-sectional area of the tip of the ear portion of the electrode plate group is reduced, so that the welding heat capacity of the ear portion is reduced. Therefore, the cast-on-strap method facilitates the welding of the tip of the ears of the electrode plate with a certain amount of molten lead. Furthermore, since the thickness of the lower part of the electrode plate is thicker and the welding heat capacity is larger than the tip of the ear part, it is possible to obtain a stable welded state in which only the electrode plate ear surface is welded, and the strap and electrode plate The mechanical strength and corrosion resistance at the interface with the ear of the group will not be impaired.

になっている。Example An example of the present invention will be described. FIG. 1 is a perspective view of an electrode plate. The electrode plate 2 has an ear portion 1 having a uniform thickness at the tip and a lower portion having a thicker block shape than the other portions of the ear portion 1. Is. FIG. 2 shows a manufacturing method of the cast-on-strap method in which the ears 1 of the electrode plate group, the strap and the pole are integrally welded. 3 is a separator for forming a plate group together with the positive and negative plates 2 and 4 is a mold provided with a recess for forming a strap pole 6 on the ear of the plate group. Insert part 1 upside down. Reference numeral 5 is a molten lead which is made of a lead alloy and is injected into the die 4 having a recess. FIG. 3 shows a state of the electrode plate group which is obtained by removing the lead molten metal 5 from the mold 4 and solidifying the molten metal 5, and 6 is a positive and negative electrode plate strap pole. FIG. 4 shows a welding state of the lead 1 and the ears 1 of the positive and negative electrode plates 2 in FIG. 2, and FIG. 4 (b) shows that the ears 1 of the conventional electrode plate 2 have a uniform thickness. Because of the positive and negative plates 2, the welding heat capacity of the ears 1 of the electrode plate 2 is large, and the solidification rate of the lead melt 5 is fast. Therefore, 7 is the ears 1 of the positive and cathode plates 2 and the lead melt 5. A crack is generated in the strap from the ear portion 1 of the electrode plate 2 in the concave portion formed between the two. (A) shows that the thickness of the ear portion 1 of the electrode plate 2 of the present invention is uniform and thin at the tip and thicker in a block shape than the other portions of the ear portion 1 at the lower portion thereof. Since the welding heat capacity at the tip of the ear 1 of the electrode plate 2 is small, the welding is facilitated. Further, the thickness of the lower portion of the electrode plate 2 is thicker than the tip of the ear 1 of the electrode plate 2, and the welding heat capacity of the electrode plate 2 is large. Only the surface is welded, and 8 is a good welded state at the raised portion 8 which is slightly formed between the cathode plate 2 and the lead molten metal 5.

工業的価値大なるものである。Effects of the Invention The present invention is a positive electrode in the cast-on-strap method of integrally welding the electrode plate ear portion of the lead storage battery and the strap or the pole, and improves the welding state of the ear portion of the cathode plate and the strap, Since the thickness of the positive and negative electrode ears is thin and uniform at the tip and thicker in the lower part in a block shape than the other parts of the ears, the welding heat capacity at the ears of the electrode plate is small. On the contrary, at the lower end of the tip, the welding heat capacity becomes large, so when the ears of the electrode plate are immersed in lead molten metal, it is easy to weld the ears of the electrode plate together with the brushing treatment on the surface of the ears. In the lower part of the tip, since the surface of the ears of the electrode plate is welded, there is a slight bulge between the lead molten metal and the ears of the electrode plate. Without compromising the mechanical strength and corrosion resistance at the interface of
It has become possible to obtain a stable welded state similar to oxygen-hydrogen gas burner welding. As described above, the present invention is
It has great industrial value.
