Name of the present utility model is called a kind of lead acid accumulator plate grid.Belong to battery technology field.It mainly solves existing punching grid and there is lead plaster poor adhesive force, and production process easily falls cream, affects the problem of battery performance.Its principal character comprises: comprise grid; The thickness of described grid is 0.3 ~ 2mm, surface for roughness be the surface of 3.2 ~ 12.6; Grid to fill or coated plate has lead plaster; Slab lattice thickness is thinner than 1mm.The utility model has the advantages that the adhesion, the slab lattice thickness that improve punching grid and lead plaster can be thinner than below 1mm, is particularly useful for the punching grid of manufacture high power storage battery.
Description
Technical field
The utility model belongs to battery technology field.Be specifically related to a kind of lead acid accumulator plate grid.
Background technology
Traditional lead acid batteries grid adopts gravity casting mode to produce, technology maturation, but the shortcoming having that weight is large, production efficiency is low, not corrosion-resistant, process quality control deviation is large.There is the stretch grid afterwards, lightweight, production efficiency is high, corrosion resistance is strong, but because there is no left and right side frame, there is grid short circuit of should growing up and cause battery to shift to an earlier date the shortcoming of end-of-life.Adopt the punching grid that the cold rolling mode of machine is produced, have that corrosion-resistant, lightweight, life-span is long, production process is simple, the feature of steady quality, convenient management, grid can do thinner, thickness evenly, meet current lead acid accumulator to high power, energy-conserving and environment-protective technique direction development trend.
But punching grid alloy is fine and close, smooth surface, and the poor adhesive force of lead plaster, production process easily falls cream, affects battery performance.
The forming method of tradition punching grid is as follows:
1. 6. grid is shaping to prepare the punching of lead alloy → 2. smelting lead alloy → 3. cast stereotype → 4. suppress. g., lead tape → 5..
Summary of the invention
The purpose of this utility model provides a kind of lead acid accumulator plate grid for above-mentioned deficiency exactly, improves the adhesion of punching grid and lead plaster.
Technical solution of the present utility model is: a kind of lead acid accumulator plate grid, comprises grid, it is characterized in that: the thickness of described grid is 0.3 ~ 2mm, surface for roughness be the surface of 3.2 ~ 12.6; Grid to fill or coated plate has lead plaster.
Slab lattice thickness described in the technical solution of the utility model is less than or equal to 1mm.
The surface of the grid skeleton described in the technical solution of the utility model is the roughness adopting roll-in method, pressing, sand-blast, polishing method to carry out surface roughening process formation is the surface of 3.2 ~ 12.6.
The utility model is due on the basis of existing punching grid forming method, first carry out after continuous punching, forming the grid skeleton that thickness is 0.3 ~ 2mm through porous punch press, roughening process is carried out again on the surface of continuous print grid skeleton structure, form the surface of 3.2 ~ 12.6, thus the roughness of grid surface and the surface area of grid can be increased, when carrying out pole plate lead plaster and filling, make can form good combination interface between grid and lead plaster, thus the internal resistance reducing battery improves the discharge performance of battery, be particularly useful for manufacturing high power storage battery.The utility model has the advantages that the adhesion, the slab lattice thickness that improve punching grid and lead plaster can be thinner than 1mm.The utility model is particularly useful for the punching grid manufacturing high power storage battery.
