Abstract
The utility model provides a lead -acid storage battery, includes polar plate, acidizing fluid, casing, lid, plumbous utmost point post, overlaps the aluminum alloy terminal on lead utmost point post, through the butt fusion of friction welding (FW) layer between aluminum alloy terminal and the plumbous utmost point post. The friction welding (FW) layer is located aluminum alloy terminal and the plumbous extremely upper end of post. The utility model provides a prior art battery to consume plumbous volume big, the soft terminal intensity that leads to the fact of texture is not enough, has the problem of the risk of breaking, improves back terminal weight only 14, reduces plumbous in the battery production and consumes, reduces battery weight, aluminium has fine electric conductivity, guarantees the battery and normally works, aluminium has the oxide layer, can resist the acidizing fluid and corrode, the more plumbous hardness of aluminium is big, and intensity is high, can stand higher binding post fastening power.
Description
Technical field
The utility model belongs to Lead-acid Battery Technology field.
Background technology
The electrode of lead acid accumulator is made primarily of plumbous and oxide, and electrolyte is sulfuric acid solution.Although lead acid accumulator relative to lithium battery, Ni-MH battery homenergic is low, the deeper cavity life-span is short, but because self discharge is little, high temperature performance is superior, produce and recovery technology is ripe and cheap advantage, this battery remains in the world that output is maximum at present, the dynamic origin that purposes is the widest.Lead acid accumulator is applied in tractor, tricycle, automobile starting etc. mostly.
Lead alloy (leadalloys) take lead as the alloy that base material adds other elements composition.Lead alloy is widely used in the industries such as electrolytic zinc, cathode copper and storage battery.Density is large, fusing point is low owing to having for lead alloy, the corrosion-resistant and protection features such as radiological performance is good, and application is wide, and other metals cannot substitute.Lead alloy is mainly used in the industries such as electrolytic zinc, cathode copper and storage battery.
Lead-acid storage battery outer case and vehicle are connected with 2 binding posts, usually this terminal material is lead alloy, lead alloy terminal is welded with inside battery lead terminal post by melting welding, and the material of terminal and pole makes lead alloy terminal and inside battery lead terminal post well merge.Fusion process is specially, by welding point in the effect of high temperature etc. down to molten state, because welded piece lead alloy terminal and inside battery lead terminal post closely stick together, under the effect of temperature field, gravity etc., not plus-pressure, what lead alloy terminal and inside battery lead terminal post melted melt liquid can there is mixing phenomena, after temperature reduces, melt portions is condensed, and lead alloy terminal and inside battery lead terminal post just by firmly welded together, complete welding.Plumbous shortcoming is density large (11.34 grams/cc), and quality is soft, gains in weight, and has lead alloy terminal by the risk of wiring clamp crimp.
Summary of the invention
The utility model provides a kind of lead acid accumulator for overcoming the defect of prior art, at guarantee satisfactory electrical conductivity simultaneously, reduces weight, improves intensity, increases the installation firmness with binding post.
The technical solution of the utility model is: comprise pole plate, acid solution, housing, lid, lead terminal post, the aluminium alloy terminal be placed on lead terminal post, by the welding of friction welding (FW) layer between aluminium alloy terminal and lead terminal post.
Friction welding (FW) layer is positioned at the upper end of aluminium alloy terminal and lead terminal post.
Friction welding process is specially, under pressure, under effect that is constant or that increase progressively pressure and moment of torsion, the relative motion between welding contact end face is utilized to produce frictional heat and plastic deformation heat at rubbing surface and near zone thereof, make and near zone temperature rise to close to but generally lower than the temperature range of fusing point, the resistance of deformation of material reduces, plasticity improves, the oxide-film at interface is broken, under the effect of upsetting force, produce plastic deformation and flowing with material, realized the solid State Welding welded by the molecular diffusion at interface and recrystallization.Friction welding (FW) is made up of following four steps usually: 1, changes mechanical energy is heat energy; 2, material plasticity distortion; 3, the forging force under thermoplasticity; 4, intermolecular proliferation recrystallization.
Friction welding (FW) is compared the maximum difference of traditional melting welding and is in whole welding process, and metal acquisition energy to be welded raises the temperature reached and do not reach its fusing point, and namely metal is the class forging state solid diffusivity realized under hot plastic state.Relatively traditional melting welding, it is high that friction welding (FW) has quality of weld joint---and can reach weld strength and basis material equal strength, welding efficiency is high, steady quality, consistency be good, can welding dissimilar materials etc. be realized.The utility model uses aluminium alloy terminal, and adopt friction welding (FW) mode aluminium alloy terminal and inside battery lead terminal post can be merged very well, aluminium density only has 2.78 grams/cc simultaneously, at guarantee satisfactory electrical conductivity simultaneously, reduce weight, improve intensity, increase the installation firmness with binding post.
The utility model solves the plumbous amount of prior art battery consumption greatly, and quality is soft causes terminal undercapacity, has the problem of risk of rupture, improves rear terminal weight and only has 1/4, reduces the lead loss in battery production, reduces battery weight; Aluminium has good conductivity, ensures normal battery operation; Aluminium has oxide layer, can resist acid liquid corrosion; Aluminium is large compared with plumbous hardness, and intensity is high, can stand higher binding post fastening force.
