Description
Technical field
The utility model relates to a kind of large-diameter line base on-line continuous hot-dip tinning stack.
Background technology
Along with improving constantly of social development and human living standard, commercial power and civilian electric demand increase, requirement to the overhead power transmission electrical network is more and more higher, not only require wire to have higher tensile strength, guarantee to use safety coefficient, and require it to have good conductivity, and improve transmitting capacity, therefore built on stilts larger with the general wire diameter of wire.Mostly be bare wire and make somebody a mere figurehead with wire, do not have dielectric protection layer, in atmospheric environment, easily be corroded.And aerial condutor plays electrical connection and conduction, keeps the original surface characteristic of wire extremely important, does not wish that any corrosion appears in the surface.Cause the joint contact resistance to increase such as the surface corrosion meeting, the temperature that will cause in service raises.Corrosion oxidation will aggravate under the high temperature, produces vicious cycle, and contact quality is further worsened, and the accident such as cause at last the point of contact excess Temperature even can smolder, burn causes whole transmission system paralysis.Particularly working as power transmission network uses in coastal saline-alkali environment, wire is exposed in the abominable marine atmosphere, constantly stand the erosion of marine atmosphere, because the salt fog characteristics in the marine atmosphere, cause the serious brine corrosion of wire, protect and reduce the deleterious effect of salt fog so must consider a kind of technological measure.Therefore the resistance to corrosion that improves aerial condutor is extremely important.Tinned wire can utilize the functional advantage of electroplating surfaces with tin, reduces the conductive line surfaces corrosion that produces under the aforementioned atmospheric environment, effectively protects transmission system.Therefore be necessary to design a kind for the treatment of unit that can fine solution conductive line surfaces corrosion, thereby guarantee transmission system safety.
And present wire zinc-plated generally be in plating tank, to carry out, the zinc-plated time is long, and electroplates and to belong to highly energy-consuming, high pollution industry.And the wire diameter of electroplating at present is all smaller, and generally below 1mm, maximum is no more than 3mm.For the large-diameter line base, for example the Prospect of Contact Wire Materials for Electrical Railway diameter generally more than 10mm, has determined that its bending radius is larger, can't realize zinc-plated in plating tank.The hot-dip tinning stack that uses at present generally needs annealed processing, reduce surface tension, thereby zinc-plated process carried out smoothly, and this tin plating method can only to finish the minor diameter wire rod zinc-plated.And after the annealing with the strength decreased of wire rod.Therefore design is a kind of can to guarantee major diameter, the online zinc-plated tinning stack of rigid line base with regard to needing.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, and less investment is easy to suitability for industrialized production, lower-cost large-diameter line base on-line continuous hot-dip tinning stack.
The purpose of this utility model is achieved in that a kind of large-diameter line base on-line continuous hot-dip tinning stack, and it comprises drawing equipment and tin equipment, and drawing equipment comprises drawing die holder and drawing wheel hub; Tin equipment comprises washing unit, soldering device, tinning stack, tin scraping device and refrigerating unit, and described washing unit, soldering device, tinning stack, tin scraping device and refrigerating unit are set in turn between drawing die holder and the drawing wheel hub.
The beneficial effect of the utility model large-diameter line base on-line continuous hot-dip tinning stack is:
To advance into washing unit in the winding of drawing wheel hub through the large-diameter line base that drawing die draws and carry out the oil removing clean, after entering soldering device reduction surface tension, enter tinning stack and carry out the hot tinning processing, then wipe unnecessary tin off by the tin scraping device, by drawing speed and the tin scraping device of control line base, can guarantee tin thickness and zinc-plated quality on the line base.This device can be directly installed on the production unit, can realize continuously zinc-plated.Save place and cost, enhance productivity simultaneously.This apparatus structure is simple, and less investment is easy to suitability for industrialized production, and cost is lower.
Compare with electro-plating method, equipment is simple, does not need to use the larger industrial chemicals of pollution in the plating, do not produce industrial pollution, and zinc-plated efficient is high.This process using hot tinning mode, in the hot tinning process, by the tin of fusing and the reaction between the bar base surface, produce the hard and uniform intermetallic compound of one deck at substrate surface, both guaranteed extraordinary adhesive rate, form good coating, improved again corrosion resistance nature.
The utility model device is compared with common tinning stack, in order to solve the large shortcoming of rigid line base surface tension, increased soldering device, the Main Function of soldering flux is to remove oxide compound, reduces the surface tension of soldered material, and soldering flux contains tensio-active agent, show extremely strong wetting action, guarantee molten tin in the expansion of large-diameter line base surface, flow, infiltration etc., improved the Weldability of blank surface, guaranteed zinc-plated quality.
Description of drawings
Fig. 1 is the utility model large-diameter line base on-line continuous hot-dip tinning stack schematic diagram.
Among the figure: drawing die holder 1, washing unit 2, soldering device 3, tinning stack 4, tin scraping device 5, drawing wheel hub 6, refrigerating unit 7.
Embodiment
Referring to Fig. 1, the large-diameter line base on-line continuous hot-dip tinning stack that the utility model relates to comprises drawing equipment, tin equipment.Drawing equipment comprises drawing die holder 1 and drawing wheel hub 6; Tin equipment comprises washing unit 2, soldering device 3, tinning stack 4, tin scraping device 5 and refrigerating unit 7, and described washing unit 2, soldering device 3, tinning stack 4, tin scraping device 5 and refrigerating unit 7 are set in turn between drawing die holder 1 and the drawing wheel hub 6.
During work, the large-diameter line base is drawn into the semifinished or finished goods wire rod after by drawing die 1, enters then that washing unit 2 carries out oil removing, removal of impurities is processed.Because because the effect of cold working hardening, surface tension is larger behind the wire drawing, therefore will enter through the line base that cleans soldering device 3 and help weldering to process, by foaming, smear or the form such as spraying adhering to soldering flux on the online base, be beneficial to line base electroplating surfaces with tin.The line base that the surface scribbles soldering flux enters tinning stack 4 subsequently, in order to guarantee zinc-plated specification of quality, controls zinc-plated temperature and zinc-plated time.The line base of the zinc-plated processing of process is by tin scraping device 5, and according to the thickness requirement of tin coating, the size of control tin scraping mould is removed the unnecessary tin in tinned wire top layer.Because temperature is very high in the pot, and is very high by line base temperature behind the tin scraping mould, need by refrigerating unit 7 wire to be lowered the temperature, on drawing wheel hub 6, then enter lower road production process through overcooled tinned wire.Through the zinc-plated wire rod smooth surface that this device is produced, thickness reaches specified requirement.With the zinc-plated wire rod sabot of conformance with standard and customer requirement, finish tinned wire production at last.
