Background technology
The conduction gold utensil that copper-aluminum transition connecting terminal is connected with power device terminals for cable end piece conductor, with electricity It is tubulose that cable aluminium conductor connects one end, the flat board that the other end is given shape being connected with electrolytic copper device.Copper equipment is led with aluminum Line connects, and the electric transition of metal that two kinds of some potential differences are different occurs, and be in operation generation couple corrosion, in order to avoid electrification is rotten Erosion, the measure taked at present has copper-aluminum transition connecting terminal to be connected with wire and equipment, the copper-aluminum transition terminal that market uses Based on friction welding (FW), blast weldering, soldering.There is copper and consume excessive shortcoming in friction welding (FW), complex manufacturing, quality monitoring is more Scrapping easily occurs in difficulty, and friction welding product is added up or heavy current impact easily comes off in short-term, brings potential to use Risk;The temperature capacity of soldered fitting is poor, temperature influence is big, strength of joint is than removing surface during relatively low, soldering and weldering The requirement of part assembling quality is higher;Blast weldering annealing difficulty, produces yield rate low.Material source is difficult, the most outdoor work Industry, mechanization intensity is low, and labor condition is poor, and also climate condition limits its price is that higher scrappage is the highest.
Summary of the invention
The purpose of the present invention is in order to provide the Copper-Aluminum compound transition terminal that the simple yield rate of a kind of production technology is high Production technology.
For realizing the purpose of the present invention, the present invention adopts the following technical scheme that a kind of Copper-Aluminum compound transition terminal Production technology, comprises the following steps:
The first step: first In Crystal Solid Copper is put in fusing stove and be fused into liquid copper, enter back into and carry out degasification slag hitting in constant temperature oven After process, then liquid copper is entered by mozzle and is in the crystallizer in the compound casting device under vacuum state, and It is frozen into copper pipe at crystallizer;
Second step: solid aluminum being put in fusing stove and be fused into liquid aluminium, liquid aluminium enters back into and carries out degasification in constant temperature oven After slag hitting processes, then liquid aluminium first passes through mozzle again by the copper pipe in gate spool entrance crystallizer and solidifying with copper pipe Strike up partnership formation copper aluminum composite material, and one end of copper aluminum composite material is tubulose, and its other end is tabular;
3rd step: copper aluminum composite material is extracted from crystallizer by haulage gear, then putting down copper aluminum composite material One end of tabular is placed on backing plate, then uses the boring machine medium position boring in flat one end of copper aluminum composite material, Form Copper-Aluminum compound transition terminal;
4th step: Copper-Aluminum compound transition terminal is put in passivation pool and carry out surface process 5 minutes, put in passivation pool Entering passivating solution, the mass percent of passivating solution consists of sodium polydithio-dipropyl sulfonate 0.4%-0.6%, poly dimethyl amide groups Sodium sulfonate 0.3%-0.35%, 1-hydroxy ethylidene-1,1-diphosphonic acid 0.1%-6%, nano silicon oxide 2.1%-2.5%, two octyloxy Jiao's phosphorus Perester radical 15%-18%, surplus is water;
5th step: the Copper-Aluminum compound transition terminal in passivation pool taken out, puts into and carries out in straightener aligning operation, It is subsequently placed in buffing machine and is processed by shot blasting, improve Copper-Aluminum compound transition terminal surface accurate degree.
5th step: Copper-Aluminum compound transition terminal is taken from buffing machine, completes.
Preferably, described Copper-Aluminum compound transition terminal include aluminium material layer and be wrapped in the copper material outside aluminium material layer Matter layer, the thickness of described copper material layer is at 0.5mm-6.0mm.
Beneficial effects of the present invention: use above-mentioned manufacturing process so that Copper-Aluminum compound transition terminal one Molding, service life is long, and its production technology is simple, and the yield rate of product is high.Sodium polydithio-dipropyl sulfonate and poly-diformazan Base amidosulfonic acid sodium is brightener, has good dissolving and metathesis, and when generating ageing products in oil, polar group leads to Cross physical absorption and chemical replacement effect, remove the pollutant on metal parts surface, reach the purpose of bright quenching;Hydroxy ethylidene Di 2 ethylhexyl phosphonic acid is a kind of organophosphor acids anti-incrustation corrosion inhibitor, can form stable complex with the many kinds of metal ions such as ferrum, copper, zinc, The oxide of metal surface can be dissolved;Two octyloxy pyrophosphoric acid ester groups can improve passivating film at metal by microcosmic " molecular bridge " The adhesive force on surface, after process metal surface formed organic titanium/inorganic matter passivation layer can stop moisture, corrosive gas and Other corrosive substance contacting metal surfaces, thus improve the corrosion resisting property of metal passivating film, mechanical performance and yellowing resistance;Receive Rice silicon oxide has strong permeance property, can be applied to passivating film pore defect position in the short time, does in uniform temperature After dry, will be combined with metallic matrix, play the corrosion resistant effect in raising metal surface.
