Abstract
The utility model discloses a storage battery grid which comprises a frame and a tab, wherein the tab is fixed on the frame, the end of the tab has a thinning section, the two opponent sides of the thinning section are inclined inwards, and the thickness of the thinning section is reduced gradually towards the direction far from the frame. The storage battery grid provided by the utility model has the thinning section at the end of the tab, not only is the combination property of the tab not affected, but also the generation of air holes in the tab during a manufacturing process of the grid can be reduced, so that storage battery rosin joint caused by the existence of the air holes is prevented, and the product quality of a storage battery is improved.
Description
Technical field
The utility model belongs to the production technical field of storage battery, is specifically related to a kind of battery grid.
Background technology
Lead acid accumulator belongs to reversible dc power supply, can change chemical energy into electric energy, also can change electric energy into chemical energy simultaneously.Lead acid accumulator is mainly made up of electrolyte, groove lid and utmost point group, the electrolyte of lead acid accumulator is sulfuric acid solution, wherein utmost point group is mainly made up of positive plate, negative plate and dividing plate, dividing plate mainly plays storage electrolyte, as the compound gas passage of oxygen, play prevent that active material from coming off and positive and negative electrode between the effect of short circuit.Wherein pole plate is made up of grid and the active material material being coated on grid, and grid is made up of rib crisscross in lug, frame and frame, mainly plays the effect of supporting active material and afflux.
In the production of grid, mainly comprise and drawing in the net and the two kinds of production technologies of casting, wherein casting is under Action of Gravity Field, the lead alloy of heat fused to be poured in plate grid die, then cooling forming; Draw in the net is that lead band by certain width is made fixing slot, stretched moulding on punch press.The lead alloy material that grid is conventional mainly comprises lead-antimony alloy and lead-calcium alloy, lead-antimony alloy has good casting and deep-circulating performance, tensile strength, ductility, hardness and the Grain Refinement Effect of lead-antimony alloy are better, therefore there is good casting character, but while using lead-antimony alloy as the material of grid, easily produce antimony poisoning phenomenon, do not meet environmental requirement.
Mostly use at present the lead alloy material of lead-calcium alloy as grid, but the casting character of lead-calcium alloy is poor, and mobility is bad, and forming area is narrow, when casting, gas is difficult for discharging in die cavity, therefore inner inclusion bubble while easily causing grid to be shaped, thus pore, particularly lug position formed, be easy to produce inner air vent, in the time lug being carried out to bus-bar welding, be easy to produce the generation of the situation such as rosin joint, dry joint, thereby affect the performance of battery.
Utility model content
The utility model provides a kind of battery grid, avoids the generation of lug inner air vent.
A kind of battery grid, comprise frame and be fixed on the lug on frame, there is a thinning section end of described lug, and there is a thinning section end of described lug, two of described thinning section side in opposite directions slopes inwardly, and the thickness of thinning section is towards reducing gradually away from the direction of frame.
In the manufacture process of grid, because the mobility of lead-calcium alloy is poor, in the grid that can make casting form, produce pore, the utility model arranges a thinning section in the end of lug, in the time manufacturing grid of the present utility model, in casting mould, cast the die cavity thickness generation respective change of lug, therefore make the charging quantity of this required lead-calcium alloy in position reduce, the lead-calcium alloy flow dispersion that flow to this position is very fast, exhaust is abundant, has avoided because the flowing forming of lead-calcium alloy is compared with the generation that causes slowly lug inner air vent.
In the time that the thickness of lug changes, unaffected in order to guarantee the combination property of lug, two parallel with frame lug side attenuates are obtained thinning section of the present utility model by the utility model, two side opposite tilts of its thinning section, from the thickness of thinning section towards reducing gradually away from the direction of frame.
The electric conductivity of lug is relevant with the cross-sectional area of lug, therefore while changing in order to ensure lug thickness, do not affect the electric conductivity of lug, the utility model makes lug have the cross-sectional area of suitable size by controlling the gradient of thinning section side and the length of thinning section.
As preferably, the angle that the plane at described side and frame place forms is 8～10 °.
As further preferred, the angle that the plane at described side and frame place forms is 8 °.
As preferably, the length of described thinning section is 3～5mm.
As further preferred, the length of described thinning section is 4mm.
The end face of described lug is the conical surface.
The utility model battery grid is provided with a thinning section in the end of lug, not only do not affect the combination property of lug, and can reduce the generation of lug inner air vent in grid manufacture process, thereby prevent from causing the problems such as storage battery generation rosin joint, dry joint due to the existence of pore, improved accumulator product quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of battery grid.
Fig. 2 is the planar structure schematic diagram of lug.
Embodiment
As shown in Figure 1, battery grid of the present utility model comprises frame 1, lug 2 and staggered lengthways of rod and the horizontal rib of being located in frame 1, and wherein lug 2 is fixed on frame 1 one sides.
As shown in Figure 2, the end face of lug 2 is the conical surface, and has a thinning section 21 in the end of lug 2, two side opposite tilts of the utility model thinning section 21, and the thickness of thinning section 21 is towards reducing gradually away from the direction of frame 1.Because grid of the present utility model has above-mentioned special construction, therefore when grid of the present utility model is in casting mould when casting, in casting mould, cast the die cavity thickness generation respective change of lug, the charging quantity of this required lead-calcium alloy in position is reduced, the lead-calcium alloy flow dispersion that flow to this position is very fast, exhaust is abundant, avoids the generation of lug 2 inner air vents.
In the time preventing the generation of lug 2 inner air vents, make the thickness of lug 2 that variation occur, and the shape of lug 2 will affect the combination property of lug 2 while changing, for example electric conductivity is relevant with the cross-sectional area of lug 2, the angle that in the present embodiment, the plane at lug 2 sides and frame 1 place forms is 8 °, the length of thinning section is 4mm, can guarantee that lug 2 keeps good electric conductivity, and find through test of many times, the angle that the plane at lug side and frame 21 places forms is 8～10 °, when the length of thinning section is 3～5mm, all can there is good electric conductivity.
