Abstract
The process of shifting long copper bar continuously and tin plating with jet flow includes passing the long copper bar through a miniature electroplating bath, and jetting plating solution to the copper bar in high speed upwards with jetting pipes for electroplating the four surfaces of the copper bar in continuous moving. The process has high homogeneity of plating solution and great allowed current density. The present invention has the advantages of low investment, simple operation, capacity of realizing complete plating and local plating, high plating quality, etc.
Description
Technical field
The present invention relates to the electroplating technology field, specifically a kind of method and apparatus of long copper row continuous moving jet tin plating.
Background technology
In electric power, electrician, electric essential industry field, copper bar as the conduction connection carrier extensively a large amount of be used for electric switch engineering industry (as power distribution cabinet, transformer, power transmission and transformation), for anti-oxidation, improve conductive capability, copper bar (especially at overlapping part) must be coated with zinc-plated rotproofing.At present, for copper bar, being coated with zinc-platedly has following three kinds of modes to realize:
1, scald tin: original process is about to block tin and is heated to molten state and by manually smearing mode the tin layer directly is deposited over the copper bar surface.
This mode shortcoming is: the loss of (1) tin material is big, cost is high; (2) tin thickness is extremely inhomogeneous, tin coating foreign matter content height; (3) poor working environment, smog infringement health; (4) labour intensity is big, inefficiency.It is deposited that this technology is suitable for the local overlapping part of copper bar.
2, groove plating (plating): traditional technology is about to desire electroplate in copper facing composition portion or the whole standing groove, makes the tin layer be covered in the copper bar surface.
This mode shortcoming is: (1) one-time investment cost is big; (2) tank liquor maintenance cost height, energy consumption is big; (3) be subjected to the coating bath spacial influence can't realize that the integral body of superlong copper gang plates.This technology is suitable for some parcel plating of copper bar or the whole plating of finite length.
3, brush plating (selecting to electroplate): improved technology is promptly by the charged brush of manual manipulation, dips in to move around on the copper bar surface after getting plating bath, forms coating.
The shortcoming of this mode is: (1) human factor is bigger to the quality of coating influence; (2) the coating uniformity coefficient is difficult for grasping; When (3) especially long copper bar needed whole brush plating, the coating outward appearance was difficult to guarantee consistent, often causes secondary pollution in the brush plating process easily, makes the coating jaundice blacking up; (4) big, the worker of labour intensity leads low.This technology is suitable for the local overlapping part brush plating of copper bar.
Summary of the invention
The objective of the invention is to develop and a kind ofly utilize miniature plating tank that the long copper bar that moves is implemented plating, and the method and apparatus of the long copper row continuous moving jet tin plating that coating is even, work efficiency is high.
The method of long copper row continuous moving jet tin plating of the present invention, comprise: long copper bar passes through miniature plating tank in moving, utilize the jet pipe in the miniature plating tank to go up ground extremely down to the injection of the copper bar circulation high-speed and continuous in groove plating bath, make plating bath concentration polarization in electroplating process drop to minimum, allow current density the highest, guarantee that in the process that moves continuously the desire plating place disposable uniform high-efficiency of finishing in copper bar four sides is electroplated.
Jet plates except zinc-plated, all right nickel plating, zinc-plated or other metal-plated.
It is exclusive that jet plating removes copper facing, can also the copper facing pipe, copper cash, copper strips (narrow boards), or other metal tube, line, band.
The method of long copper row continuous moving jet tin plating is called for short the jet plating.
The plating of this method jet also can change brush plating into very easily.
Copper bar is zinc-plated should to be washed, dry, encapsulate after finishing, in order to using.
Long copper row continuous moving jet tin plating equipment of the present invention, comprise: liquid holding groove 7., liquid holding groove 7. the top be equipped with miniature plating tank 1., roller 6., jet pipe 8. be contained in miniature plating tank 1. in, 2. link to each other with pipeline with high pressure pump, 7. 2. high pressure pump link to each other with liquid holding groove with pipeline, zinc-plated power supply positive and negative electrode 3. respectively with miniature plating tank 1., 4. long copper bar link to each other.
Tin plating solution and technology are similar with existing plating solution and technology basically.
The advantage of the method and apparatus of long copper row continuous moving jet tin plating of the present invention is: little, the instant effect of (1) investment, repayment height; (2) Installation and Debugging are convenient, and are simple to operate flexible; (3) both can realize not being subjected to the whole plating of copper bar limitation of length, can realize the local plating of copper bar overlapping part again; (4) take into account the function of electroplating with brush plating, kinds of processes; (5) volume is little, in light weight, not high to site requirements, can realize the on-the-spot copper bar coating that connects in engineering field; (6) long copper bar jet plating can be carried out synchronously with the water flushing, and coating is even, outward appearance is consistent, limit plating marginal rot erosion tin layer can not occur, makes it the secondary pollution problem of turning to be yellow blacking up; (7) low, the worker of energy-saving material-saving, cost leads soon, can realize mass production; (8) reduce labour intensity significantly.
Research and development by the long copper row continuous moving jet tin plating technology, make the tin coating quality meet that GB/T12599-1990 metal cladding tin electrolytic coating GB requires, consistent beautiful, the anticorrosion conductivity attractive in appearance of its coating outward appearance is good, can satisfy fully in electric power, electrician, electric field need of industrial production, have the vast market development prospect.
