Abstract

The utility model relates to a pole rod, which is arranged in plating bath and connected with the power supply equipment so as to ensure the electroplating work is performed smoothly, and comprises a high-intension metal rod, a conduction layer with best conductive metal end, and a protection layer with anti-corrosion metal wrap. The pole rod is made from a plurality of metal, and with anti-oxidation function during electroplating process. So the plating solution cannot be polluted and can be used for longer period.

Description

Electrode bar

Technical field

The utility model relates to plating, is meant a kind of electrode bar especially.

Background technology

Electroplating industry is flourishing gradually along with various weight industry at present; electroplating is exactly general general reference is reflected at a plating skim on the object with electrolytic reduction method; because the body surface after electroplating has the double effectiveness of decorating of protection; other characteristic also is provided in addition; as high conductivity, height light reflective or function or the like, so electroplating industry quite comes into one's own.

During plating; be with a conductive electrode bar (because electroconductibility the best of copper metal; so generally normally make with the copper metal) as anode; so that produce the dissociation of metal ion in the electroplate liquid; workpiece to be plated is normally as negative electrode; and the metal ion that is run off in the electroplate liquid; then replenish by the anodic pure metal; the general common nickel that has; chromium; tin; copper; the solution of silver and gold or the like; when it is electroplated; be behind input voltage between anode and negative electrode; its electroplate liquid is because of electrolytic reaction precipitating metal ion; and these metal ions can be swum to negative electrode; and after cathodic reduction; the coat of metal on the workpiece to be plated surface is being plated in formation; because the surface of electrode bar is easy to generate oxidation; generate the oxide compound (be commonly called as and be verdigris) of copper metal; making to mix in the electroplate liquid has behind the copper metal oxide and produces deterioration, in recent years, because the former material cost of copper metal significantly improves; general tradition adopts the metal electrode bar of full copper; cost height not only, and oxidation can take place in electroplating reaction, and cause raise cause conducting electricity bad; the generation of its oxide compound also can be quickened the deterioration of electroplate liquid, so be necessary to be improved.

Because above-mentioned demand, the utility model the designer hence study intensively, and long-pending individual is engaged in the many years of experience of described cause, designs a kind of brand-new electrode bar eventually.

Summary of the invention

Main purpose of the present utility model aims to provide a kind of anti-oxidation electrode bar, not only can make more durable of electroplate liquid, and its conduction speed also can obtain to promote.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of electrode bar; be to be installed in the plating tank of an electroplating machine; and can be electrically connected with an electric power supply apparatus; so that electroplating process is smooth; at first be the metallic substance that intensity is high, make a barred body in one-body molded mode, and as the center of electrode bar; improve its integral intensity; then, again with the good metallic cover of electroconductibility in the barred body outside, to form a conductive layer; increase its electroconductibility; at last, again that erosion resistance is good metallic cover is at outermost layer, to form a protective layer; the utility model is used in when electroplating, and can avoid electrode bar and electroplate liquid generation effect.

Described barred body is a ferrous metal.

Described barred body is a stainless steel.

Described conductive layer is the copper metal.

Described conductive layer is a silver metal.

Described protective layer is a titanium metal.

Compared with prior art; adopt the advantage that the utlity model has of technique scheme to be: not only intensity is better, electroconductibility is good for it; the more important thing is that the surface can not corrode; and can protect conductive layer not oxidized; with the work-ing life of increase electroplate liquid, and the practicality of tool utility model and progressive.

Embodiment

See also Fig. 1; be scheme of installation of the present utility model; as shown in FIG.; the utility model is when installing and using; be that several electrode bars 10 are formed electrode row to be arranged side by side; and be installed in the plating tank 30 of an electroplating machine 20; electric shock is arranged in the electroplate liquid 301 that is fully immersed in the plating tank 30; be electrically connected with an electric power supply apparatus 40 again; anode as the power supply usefulness in the electroplating reaction; behind input voltage between anode and negative electrode; its electroplate liquid is because of electrolytic reaction precipitating metal ion, and these metal ions can swim to negative electrode, and after cathodic reduction; the coat of metal on the workpiece to be plated surface is being plated in formation, so that its plating is smooth.

See also Fig. 2, be structural representation of the present utility model, as shown in FIG., electrode bar 10 of the present utility model is to make by several metal is one-body molded, it comprises: a barred body 101, be with the high metallic substance (as: ferrous metal of intensity, stainless steels etc.) one-body molded is bar-shaped, and as center of the present utility model, can significantly improve its intensity, the intensity that can remove the existing metal current conducting rod of fine copper from is softer, and easily because the shortcoming of being clashed into or impacting and damaging, because current conducting rod 10 in use, must rearrange electrode row earlier, its intensity also can be convenient to its assembly working and carry out after improving; One conductive layer 102, it is the outside that is coated on its barred body 101 with the good metal of electroconductibility (as: copper metal, silver metal etc.), to increase its electroconductibility, after adding its coating, be to form inside and outside two, also can significantly increase the area of conduction, therefore, increased the electric current passband when electroplating, can accelerate its galvanized speed, with the quality that promotes plate surface; One protective layer 103; be to be coated on outermost layer of the present utility model with the good metal of erosion resistance (as: titanium metal); after the utility model is immersed in electroplate liquid; can avoid conductive layer 102 and electroplate liquid to produce chemical action; and the oxide contaminant electroplate liquid that produces, therefore, use of the present utility model after; can avoid the deterioration of electroplate liquid, to prolong its work-ing life.

As mentioned above; the utility model is after it implements according to this; be that it is formed electrode row; and put into plating tank inside; it is fully immersed in the electroplate liquid,, arranges and be convenient to be assembled into an electrode because intensity was strengthened; rely on uncorruptible protective layer; be positioned at inner conductive layer with protection, make it can oxidation, can reach really provides a kind of anti-oxidation electrode bar; when plating is carried out; can avoid its surface to produce oxide compound, make electroplate liquid impurity occur and deterioration, therefore; use of the present utility model after, its electroplate liquid is durable more also.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
