Description
Technical field
The present invention relates to a kind of welding method of wire rod, the welding method of particularly a kind of copper-in-aluminum enameled wire and copper cash.
Background technology
Existing welding is general adopts leaded scolder heating and melting directly to weld two kinds of wire rods that hang together, and the collocation of two kinds of wire rods is firmly not strong, owing to existence plumbous in the scolder makes that the pollution of this welding procedure is bigger, is unfavorable for environmental protection simultaneously.The patent No. is composition and the application thereof that 01808699.3 Chinese patent discloses a kind of lead-free solder, and it is to prevent the broken string accident person of taking place when being carried out scolding tin as the insulation of heart yearn by the conductor in the electronic component of film conductor with copper or the alloy that contains copper.Its solution is the copper (Cu) that will contain 5.3 to 7.0wt%, with 0.1 to the nickel below the 0.5wt% (Ni), the rest is that the Pb-free solder alloy of tin (Sn) carries out fusion in 400 ℃ to 480 ℃ scope, to being carried out scolding tin as the insulation of mother metal by the connecting portion of film conductor with copper.It also is a kind of welding that overlaps the order of adopting the back, and is only applicable to the welding of copper cash and conducting element.Also having an application number is that 03207332.1 Chinese patent application discloses a kind of heat bonding and directly welds special thick compound enamel-cover copper stranded conductor, and it comprises at least two enamel covered wires (single line), and single line has two insulating barriers and an external coating.Be twisted into the enamel-cover twisted wire by many single lines through high accuracy.This heat bonding is directly welded special thick compound enamel-cover copper stranded conductor and is had good flexibility, folding resistance, proof voltage, film integrity, hyperthermia impact properties, and paint film is difficult for breaking, and Distribution of Magnetic Field is even, kelvin effect is little, and transmission characteristic is good.The high frequency voltage bearing capacity is strong, and anti-corona ability is strong.Also have lubricated, wear-resisting, characteristics such as straight weldering, be convenient to the coiling of coil windings, be applied to color monitor (pipe) deflection coil, also can be widely used in various high-frequency timing, special machines, national defense industry, electrical equipment winding such as heat-resisting, cold-resistant, need not dipping lacquer bonding, need not can directly weld by coating removal, simplified manufacturing technique, and do not have the dipping lacquer environmental pollution.But such scheme relatively is suitable for the heat bonding of copper cash and copper cash, be not suitable for different metal the end of a thread between be connected.The patent No. is 96238273.6 Chinese patent; the clad welded device of the production copper-clad aluminum conductor of using in a kind of compound wire coating field is disclosed; comprise workbench, reducing gear, clad welded mechanism, inert gas shielding mechanism; feature is; have several in the design to the line of centres of blank outlet of workbench upper edge charging aperture to multistage vertical forming roller and horizontal form roller; they are and distribute alternately, and the radius of curvature of its profile reduces step by step.Under inert gas shielding, weld automatically.Its advantage is: the copper-clad coating does not have burr, and speed of production is fast, copper and aluminium non-oxidation, and both are in conjunction with good, and expense is low, and is pollution-free.But it relates generally to a kind of frame for movement, does not disclose concrete processing step.
Summary of the invention
The invention provides and twine the method for attachment that weld the back, solved problems such as existing in prior technology connects inadequately firmly, the easy oxidation in welding back.
Above-mentioned technical purpose of the present invention solves by the following technical programs:
The welding method of copper-in-aluminum enameled wire and copper cash, it may further comprise the steps:
A, with melts soldering tin to 280～350 ℃;
B, the lead-out wire of copper-in-aluminum enameled wire is twined copper cash, the described spiral that is wound up as twines;
C, will twine part and flood in the spirit solvent of rosin, will twine part then and flood in scolding tin 0.5～1.5 second, will twine and partly flood in the spirit solvent of rosin, the winding after will flooding in solvent was partly flooded in scolding tin 1.5～2 seconds again.
The welding procedure of copper-in-aluminum enameled wire and copper cash, because the particularity of copper cover aluminum wire rod, in the process of welding, the control of welding temperature and time is quite crucial.Owing to, can make to be unlikely to make winding part of the present invention after welding, to produce embrittlement by scolder of the present invention and more complete simultaneously by the fusion at weldering position at specific temperature fusing scolding tin.
As preferably, the pitch that the lead-out wire spiral in the B step twines copper cash is 1～1.5mm.Described pitch is the distance between adjacent two lead-out wires that are wrapped on the copper cash.
As preferably, melts soldering tin to 280～300 in the described A step ℃.Welding temperature is one of key factor of influence technology of the present invention, and the too high weld that causes easily of welding temperature is oxidized in welding, is easier to embrittlement; Welding temperature is crossed much lower gas and is difficult to get rid of, and the easy like this rosin joint that causes makes that the contact resistance of weld is bigger owing to form more pore simultaneously.Select welding temperature at 280～350 ℃, the viscosity of scolding tin and welding effect reach a kind of balance.At this moment welding reaches efficient preferably.
As preferably, described spiral is wound up as and twines 4～5 circles.After being wrapped with 4～5 circles, realized connecting the function of conducting substantially, can cause the waste of material and the complexity of operation if twined many again.
Therefore, the present invention has firm welding, characteristics such as oxidation are stablized, are difficult for to resistive performance.
