Abstract
The invention provides a method for manufacturing a super-long service life electric iron welding nozzle with molten soldering erosion resistance and a process flow thereof. According to the different penetrated metal, compared with the common 'long service life welding nozzle', the service life of the electric iron welding nozzle can be doubled.
Description
Technical field
The present invention relates to ultralong service-life electric soldering iron welding nozzle fabrication technique.
Background technology
Electric soldering iron welding nozzle (hereinafter to be referred as tip) is the vitals of electric iron, and consumption is very big.The material of making tip generally all adopts the good fine copper of thermal conductivity to make, but the poor ability of its anti-fusion scolding tin etch (hereinafter to be referred as corrode), the life-span is very short.For prolonging its life-span, generally the way of Shi Yonging is to electroplate one deck iron on the fine copper matrix that has been shaped, with protection copper matrix not by corrode, i.e. so-called " long lifetime welding head ", but its effect is still limited.Especially adopting the pb-free solder environment-protective process, when welding temperature must increase substantially, corrosion was strengthened, and the tip spending rate aggravates naturally, and the tip life-span is more over half than original reduction, even world first-class brand is also unavoidable.Its direct result is exactly that the electrical apparatus industry production cost strengthens, and waste is serious.
Chinese patent 95238334.9 specification sheetss disclose compound electric soldering bit of a kind of long lifetime, the head of copper matrix by glued joint, welding or electroplate the anti-scolding tin etch layer that is connected, outside anti-scolding tin etch layer, also be fixed with one deck anti oxidation layer, be used for improving the anti-scolding tin etch of welding head and the ability of resistance to high temperature oxidation, prolong the work-ing life of welding head.But the material of this anti-scolding tin etch layer is iron, nickel, silicon, aluminium and their alloy, is anti-scolding tin etch material commonly used, and the effect of anti-scolding tin etch is unsatisfactory, and the method that is connected of anti-scolding tin etch layer and copper matrix is not suitable for industrial utilization.
Chinese patent 200510071035.5 specification sheetss disclose " a kind of integral refractory and corrosion resistant long life digital display temperature regulating electric soldering iron ", electroplate or dip calorizing at the welding head position that contacts with scolding tin, through after the oxide treatment, in the outside of the zone of oxidation of aluminizing evaporation one deck conductive oxide glass-ceramic layer, then in glass-ceramic layer outside nickel plating, to improve the work-ing life of welding head.This method technology is loaded down with trivial details, wastes time and energy very much, is not suitable for industrial large quantities of applying.
Summary of the invention
The object of the present invention is to provide a kind of ultralong service-life electric soldering iron welding nozzle fabrication technique.
Basic design of the present invention is: the iron plating by special metal element (is example with the metal molybdenum) is infiltrated the tip surface, to change the method for its weave construction, make it to become the anti-corrode layer of excellent performance, and significantly improve the tip life-span.
The present invention realizes by implementing following production method and technical process:
(1) the tip surface electric plating iron of earlier fine copper being made;
(2) tip of plating iron and molybdenum materials place rough vacuum and are filled with in the barrel-shaped negative electrode of argon gas, form anomalous glow discharge, produce argon ion and molybdenum ion, at a certain temperature, at the molybdenum enriched layer of tip head surface formation high-energy, high density, and along plating iron layer crystal bulk defects rapid diffusion, from outward appearance to inner essence, penetrate into plating iron layer inside, form and annotate infiltration layer, promptly special anti-corrode layer;
(3) other position electrodeposited chromium or nickel chromium triangle on the plating iron layer, protection iron layer is not oxidized;
(4) hot tinning on the anti-corrode layer of tip head, tining when being beneficial to work.
The tip that the technology of the present invention is made owing to the weave construction of anti-corrode layer and the change that matter has taken place performance, becomes the specific alloy phase of fine and close pore-free.According to the difference (or molybdenum or tungsten or nickel or its multicomponent alloy) of infiltrating metal, anti-corrode ability has had the raising of a times or several times than common iron plating, has greatly prolonged the life-span of tip, has significantly reduced the production use cost.
Description of drawings
This figure is a structural representation of the present invention.
Embodiment
Provide the embodiment of external-heat tip type tip below in conjunction with accompanying drawing:
As shown in the figure, the matrix 1 of tip of the present invention is made by fine copper; In its surface some is pure iron layer 2; The tip position is anti-corrode layer 3; The pure iron laminar surface is chromium coating or plating nicr layer 4; Anti-corrode laminar surface is a hot tinning layer 5.
Claims (2)
1. a making method and technical process of producing ultralong service-life electric soldering iron welding nozzle is characterized in that:
(1) on the tip that fine copper is made, electroplates one deck iron earlier;
(2) more above-mentioned tip and selected metal are placed in the barrel-shaped negative electrode, under rough vacuum argon gas condition, form anomalous glow discharge, form the enriched layer of special metal element at the iron laminar surface, and diffuse into iron plating inside, form and annotate infiltration layer;
(3) at the chromium plating of part position or the nickel plating chromium of tip;
(4) in the hot tinning of tip head.
2. (2) technical process according to claim 1 is characterized in that its specific metallic element is molybdenum or tungsten or nickel or their alloy.
