Abstract
The invention discloses a method for producing an aluminum alloy faucet. The method comprises the steps of feeding, processing, tempering, bending, welding, polishing, abrasive blasting and anodic oxidation. According to the faucet, the requirement for the small lead content of the faucet is guaranteed in manufacturing materials. The aluminum alloy wall is even and light, the casting process is eliminated, the aluminum alloy surface is smooth, the manufactured faucet is environmentally friendly, meanwhile, processing is easy, time and materials are saved, cost is low, the appearance style is lucid and lively, and changes are simple.
Description
Technical field
The present invention relates to a kind of water tap, particularly relate to a kind of production method of aluminum alloy water tap.
Background technique
Water tap is widely used in daily life, existing water tap is generally metal faucet, the body portion of water tap adopts the castings such as copper product, stainless steel material to process, the general lead tolerance of water tap of this casting is higher, the water tap that lead tolerance exceeds standard is very large to harm, but the water tap great majority of casting exceed standard at present, and even severe overweight, does not reach country and the requirement to water tap lead tolerance in the world far away.The water tap of casting is difficult to effectively detect and control in actual operation, detect lead tolerance and will carry out destructive detection, can not each carry out destructiveness detection, possible superintendent office is qualified while detecting, but detect later defective again, make the lead tolerance of water tap be difficult to monitoring, general user just more cannot detect.Casting water tap complex process, and foundry goods will have a certain amount of thickness, thereby take material, and time-consuming, effort, bad mechanical property, cost is high.
Summary of the invention
Object of the present invention is just to provide a kind of production method of aluminum alloy water tap, aluminum alloy water tap has effectively guaranteed that lead tolerance is very low, this drawing craft that is aluminum alloy is produced itself has just determined that lead tolerance can not be high, the aluminum alloy that lead tolerance is high, can not be drawn into good aluminum alloy, this has guaranteed the lead tolerance requirement of low (lead tolerance, below 0.1%, meets international ROHS standard) from making material.And steel pipe walls is evenly thinner lightweight, saved material, with aluminum alloy, make water tap and broken away from traditional technological method by casting water tap for a long time, aluminum alloy homogeneity is good, any surface finish, and mechanical property is excellent, make not only ecological, environmental protective of this water tap, also easy processing simultaneously, material-saving, saving of labor, cost are low, and the lucid and lively variation of appearance and modeling letter knot is easy.
The present invention, for achieving the above object, has consisted of the production method of aluminum alloy water tap following operation:
Blanking-processing-tempering-bending-welding-polishing-sandblast-anodic oxidation.When the aluminum alloy in the production method of described pan pipe water tap is crooked on Bending machines, in Al-alloy pipe, be inserted with movable chain steel axle or movable chain steel ball.In the production method of described aluminum alloy water tap, the welding of aluminum alloy is at the soldering opening place of wherein one end of the aluminum alloy that will weld, to coat silver powder and swallow to heat up in a steamer the paste that water stirs, and two welding mouth of pipe alignment is close to heat make silver powder fusing, then freezes with filamentary silver.Described material spray is silica sand, and granularity is 5-220 order.Described acidic electrolysis bath is that volume fraction is the sulfuric acid of 10%-30%, the oxalic acid that volume fraction is 2%-10%, the chromic acid that mass fraction is 30-100g/L, one or both in the boric acid that mass fraction is 3-lOg/L.Described anodizing temperature is 100-400 ℃, and current density is 1A/dm
3-3 A/dm
3, anodizing time is 30-120min.
Embodiment
Specific implementation process is as follows:
(1) blanking: the size by water tap requirement cuts material;
(2) processing: by the corresponding processing of the shape of water tap interface, joint is coincide mutually the material cutting, seam is tight;
(3) tempering: reduce hardness and the internal stress of aluminum alloy, be convenient to bending process below;
(4) bending: by aqueduct bending forming, when crooked for preventing aluminum alloy bending deflection, in aluminum alloy, be inserted with movable chain steel axle or movable chain steel ball, movable chain chain steel axle is square or rectangular aluminium alloy material for bending sections, movable chain steel ball is for curved tube, movable chain steel axle or movable chain steel ball are put into pipe, in bending extruding, drive steel axle or steel ball on chain to slide together, prevent bending deflection, to guarantee the level and smooth mellow and full bending curve of aluminum alloy, steel axle or steel ball size on chain are more smaller than the Inner Dimension of tubing, so that making chain can put into, after bending completes, chain is taken out, bending completes.If the connecting tube forming is straight, just do not needed crooked operation;
(5) welding: first silver powder being fallen to some distilled water before welding stirs, become pasty state, and then at the jointing of wherein one end of two interfaces that will weld, coat silver soldering powder and stick with paste, the mouth of pipe of connection is alignd and is close to, heat and make silver powder fusing, then freeze and make interface bright and clean level and smooth with filamentary silver;
(6) polishing: weld and tube wall are wanted polishing, makes to electroplate brighter;
(7) sandblast: adopt sandblasting machine to take pressurized air and material spray is ejected into the blank surface after steps A polishing as power;
(8) anodic oxidation: the blank after sandblast is placed in to acidic electrolysis bath as anode, is 100-400 ℃ in temperature, current density is 1A/dm
3-3 A/dm
3condition under carry out anodic oxidation 60-120min, blank carries out Colored after anodic oxidation.
The aluminum alloy water tap of producing by operation above has not only guaranteed from making material the requirement that lead tolerance is few, and aluminum alloy valve body wall is evenly thinner.Aluminum alloy homogeneity is good, and any surface finish is made not only ecological, environmental protective of this water tap, also easy processing simultaneously, and material-saving, saving of labor, cost are low, and the lucid and lively variation of appearance and modeling letter knot is easy.
