A kind of positive grid of the punching of high-temperature corrosion resistance, including upper side frame, lower frame, left frame, left frame and transverse bar, vertical bar, upper side frame top are equipped with plate ear, and the width dimensions of the vertical bar from top to bottom successively decrease；The width dimensions of transverse bar from top to bottom successively decrease.The utility model is easiest to the position corroded for positive grid according to the positive grid corrosion failure mode analysis (FMA) of dead battery, devises the positive grid of punching of a kind of rib width and interval width gradual change.The positive grid reinforces the superstructure easily corroded, while reducing the material investment that grid lower part is not easy corrosion location.On the one hand above structure effectively solves the battery premature failure as caused by positive grid corrosion, on the other hand reasonable control product cost, the feasibility that there is batch to promote and apply.
Description
Technical field
The utility model relates to the positive grids of a kind of battery part, especially high-temperature corrosion resistance, belong to battery technology neck
Domain.
Background technique
Lead-acid accumulator is mainly made of battery case, positive and negative pole plate, partition and electrolyte etc..Wherein, pole plate is as generation
The carrier of electrochemical reaction and become lead-acid accumulator core.Pole plate is made of grid and active material.Grid is to store
The important part of battery is uniformly distributed electric current on active material as carrier supported active material, improves active material
Utilization rate prevents pole plate from deforming.Generally there are three types of mode, gravity casting, seine, punchings for the manufacture of positive grid at present.Moulding plate
Grid thickness and weight are big, better performances, but production efficiency is low, at high cost.Punching grid using certain specification cold rolling. g., lead tape or
Lead alloy band is formed on punching machine using die punching.Compared with gravity grid casting, punching grid high production efficiency, and specific gravity
Power casting grid loss of weight 15%~20%, but punching slab lattice thickness is restricted, and is usually no more than 1.4mm.In addition, punching grid
Low energy consumption when production, and it is the developing direction of lead-acid accumulator that pollution is small.It is former using the failure of lead-acid accumulator under high temperature environment
Because being positive grid corrosion, since positive grid is always under higher electrode potential effect, main ingredient facial pallor is easy
Be oxidized corrosion be lead oxide, with the increase of charge and discharge number in battery use process, positive grid be corroded and increasingly
It is thin, or even fracture, eventually lead to battery failure.Usual battery producer extends anode by increasing the method for positive slab lattice thickness
Plate supports the erosion-resisting time, thus prolong the service life, but the thickness of the positive grid of punching is limited, therefore, designs reasonable plate
Grid structure solves the positive grid high-temperature corrosion resistance of punching and is a problem to be solved.
Utility model content
The purpose of this utility model is to provide a kind of positive grid of the punching of high-temperature corrosion resistance, the utility model is based on to corruption
Erosion failure mode is researched and analysed, and is rationally designed punching grid structure, is improved its high-temperature corrosion resistance performance, prolong the service life.
Problem described in the utility model is solved with following technical proposals:
A kind of positive grid of the punching of high-temperature corrosion resistance, including it is upper side frame, lower frame, left frame, left frame and transverse bar, perpendicular
Muscle, upper side frame top are equipped with plate ear, and the width dimensions of the vertical bar from top to bottom successively decrease；The width dimensions of transverse bar are from top to bottom passed
Subtract.
The positive grid of the punching of above-mentioned high-temperature corrosion resistance, the spacing distance between adjacent transverse bar are from top to bottom incremented by.
The positive grid of the punching of above-mentioned high-temperature corrosion resistance, the upper end width of the vertical bar is having a size of the 2-3 of lower end width size
Times.
The positive grid of the punching of above-mentioned high-temperature corrosion resistance, lower part transverse bar largest interval distance are top transverse bar minimum separation distances
1.2-1.5 times
The positive grid of the punching of above-mentioned high-temperature corrosion resistance, the width dimensions of top transverse bar are the 1.6- of lower part transverse bar width dimensions
1.8 again.
The positive grid of the punching of above-mentioned high-temperature corrosion resistance, the width of upper side frame are 2-3 times of following width of frame.
The utility model is easiest to occur rotten according to the positive grid corrosion failure mode analysis (FMA) of dead battery for positive grid
The position of erosion devises the positive grid of punching of a kind of rib width and interval width gradual change.The positive grid is to easily corroding
Superstructure reinforced, while reduce grid lower part be not easy corrosion location material investment.Above structure is on the one hand
Effectively solution battery premature failure as caused by positive grid corrosion, on the other hand rationally controls product cost, has and criticizes
Measure the feasibility promoted and applied.Under the premise of not increasing production cost, solve annoyings always the utility model for many years
Battery producer battery premature failure as caused by positive grid high temperature corrosion, improves service lifetime of accumulator.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Each list of reference numerals in figure are as follows: 1, plate ear, 2, upper side frame, 3, left frame, 4, lower frame, 5, left frame, 6, vertical bar, 7,
Transverse bar.
Specific embodiment
Referring to Fig. 1, the utility model includes upper side frame 2, lower frame 4, left frame 3, left frame 5, on upper and lower, left and right side
It is equipped with transverse bar 7 and vertical bar 6 in the rectangle frame that frame surrounds, is equipped with plate ear 1 on the top of upper side frame.The utility model is big by dissection
The life test of amount finds that, since positive grid corrosion leads to the battery of battery failure, corrosion location mainly collects with battery is returned to
In in the middle and upper part of positive grid, closer to plate ear, grid corrosion is more serious.Therefore, based on control production cost, extension product longevity
Life is to the utility model proposes designed with flowering structure:
