Embodiment Construction

[0028] Such as figure 1 , figure 2 , image 3 shown. A lead-acid storage battery grid of the present invention comprises a grid skeleton 2 and lead paste 3 attached to the surface thereof. The thickness of the grid frame 2 is 0.3~2mm, and the surface 1 is a surface with a roughness of 3.2~12.6. 12.6 surfaces. The rough surface 1 of the grid skeleton is coated with lead paste. The grid thickness can be thinner than 1mm.

[0029] A kind of lead-acid battery grid forming and surface treatment method of the present invention comprises the following steps:

[0030] 1. prepare lead alloy: prepare pre-smelted lead alloy according to the standard, same as in the existing method;

[0031] ② Melting the lead alloy: Put the pre-smelted lead alloy into the lead melting pot, heat it to 350~500°C until the pre-smelted lead alloy is completely melted, which is the same as in the existing method;

[0032] ③ casting lead plate: inject the melted lead alloy pump into the continuous lea...

Abstract

The invention relates to a lead-acid storage battery plate grid and a forming surface treatment method, and belongs to the technical field of storage batteries. In the prior art, the existing punching plate grid has disadvantages of poor adhesion of lead paste, easy paste shedding during the production process, and influence on the battery performance. With the present invention, the problem in the prior art is mainly solved. The method is mainly characterized by comprising: 1, preparing a lead alloy; 2, melting the lead alloy; 3, casting a lead plate; 4, pressing a lead strip; 5, punching, wherein continuous punching is performed on the pressed lead strip to form a continuous plate grid framework structure; 6, carrying out a plate grid surface roughening treatment, wherein a roughening treatment is performed on the surface of the continuous plate grid framework structure, the roughness is 3.2-12.6, and the plate grid production is completed; and 7, coating and filling the pole plate, wherein lead paste coating and filling is performed on the plate grid framework so as to complete the pole plate production. According to the present invention, the bonding force of the punching plate grid and the lead paste can be improved, the plate grid thickness can be thinner than or equal to 1 mm, and the method is especially suitable for production of the high-power storage battery punching plate grid.

Description

technical field [0001] The invention belongs to the technical field of accumulators. In particular, it relates to a lead-acid storage battery grid and a forming surface treatment method thereof. Background technique [0002] Traditional lead-acid battery grids are produced by gravity casting, which is a mature technology, but has the disadvantages of heavy weight, low production efficiency, non-corrosion resistance, and large deviations in process quality control. Later, the expanded mesh grid appeared, which is light in weight, high in production efficiency, and strong in corrosion resistance. However, because there are no left and right frames, it has the disadvantage that the grid should be long and short-circuited, causing the battery to end its life prematurely. The punched grid produced by machine cold rolling has the characteristics of corrosion resistance, light weight, long life, simple production process, stable quality, and convenient management. The grid can be ...
