Description
Technical field
The utility model relates to electroplating industry equipment technical field, is specifically related to a kind of anode for chrome-plating for gravure plating industry.
Background technology
In gravure plating industry, chromium plating is all the both sides platinum coated anodes of arranging with anode, and the anode of both sides is separate, does not link together.The advantage that has of this structure is easy to make, anode usable floor area is little, cost is relatively few, but exist a lot of shortcomings: the first, this anode construction can rotate and causes distribution of current inequality due to roller in process of production, as shown in Figure 3, in the time that the Q of roller 7 point progressively moves to region B from region A by rotating, current density can progressively reduce; In the time that Q point progressively moves to region C from region B by rotating, current density can progressively increase, and in whole electroplating process, current density is alternately to change.And in the technical requirements of durionise, current density is one of underlying condition, and constant current density is the important factor that guarantees chromium plating quality, and the design of this both sides anode, can generation current the variation of density, mass defects such as causing chromium coating lower hardness, wear no resistance, burn in high district, second, because only having both sides, anode distributes, the relative cathode area of annode area does not reach the ratio of 2:1, trivalent chromium in production process in plating solution can progressively rise, make solution composition unstable, must after platinum coated anode, install part stereotype additional auxiliary, could stablize trivalent chromium in plating solution (when platinum coated anode area is too small, oxidation capacity can cause trivalent chromium to raise not, but on platinum anode, install additional after auxiliary stereotype, can form plumbous oxide black film at platinum anode surface, this film can form heaped-up, can improve the real area of anode, improve the polarized potential of anode simultaneously, improve oxidation capacity, therefore can stablize the trivalent chromium in plating solution), but because the existence meeting of stereotype forms lead chromate powder in plating solution, reduce the purity of plating solution, even can make the lead chromate of minor diameter be mixed in the middle of coating, form defect, reduce coating mechanical property and anti-corrosion capability, three, gravure plating chromium plating adopts high temperature high current density production technique (60 ℃, the production technique of 65A/dm2, because this technique has high production efficiency, equipment investment is few, production capacity is high), because annode area is relatively little, too high anodic current density can cause platinum coating local shedding, the unequal fault of distribution of current on anode work-ing life short (too high current density is one of principal element causing the inefficacy of platinum anode), anode.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, reasonable in design, semicircle anode for chrome-plating that can improve electroplating quality.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of semicircle anode for chrome-plating, comprise anode rod and support, and anode rod is fixed on support, it is characterized in that: described support is arc support, and arc support bottom is formed for the arc-shaped depression portion of accommodating roller; Arc support comprises some horizontal support sheets and arc-shaped anode sheet, and arc-shaped anode sheet is fixed on horizontal support sheet, and horizontal support sheet and arc-shaped anode sheet form the reticulated structure of arc support; Anode rod stretches out the corner location that is fixed on arc support.
Further, described anode rod is fixed on utmost point bar support bar, and utmost point bar support bar is fixed on arc support.
Further, described arc-shaped anode sheet comprises two minor arc shape anode strips and some auxiliary arc-shaped anode sheets, two minor arc shape anode strips are individually fixed in the two ends of horizontal support sheet, some auxiliary arc-shaped anode sheets are evenly arranged and are fixed on horizontal support sheet, minor arc shape anode strip and auxiliary arc-shaped anode sheet and the mutual vertical interlaced setting of horizontal support sheet.
Further, described arc support is the semicircle roller support matching with roller, and the radius of semicircle roller support is greater than the diameter of corresponding roller.
The utility model, by changing conventional anode structure design, adopts semicircular structure, makes the constant distance between anode and roller, the impact that not rotated by roller, thus have the following advantages:
1, there is current density very uniformly, the impact that not rotated by roller, distribution of current is even, and electrodeposited chromium layers hardness and wear resistance improve more than 30%;
2, owing to adopting circular design, annode area improves 30%, and more than the Area Ratio of anode and negative electrode can reach 2:1, the current density of bearing on anode can reduce, and can reach original more than 2 times the work-ing life of anode;
3, because of the increase of annode area, anodic current density diminishes, and the polarization of anode diminishes, and the voltage consuming on anode also can diminish; Because of increase and the semi-circular design of annode area, also can reduce plating voltage simultaneously; By test, plating voltage reduces by 30-40% with respect to traditional both sides anode, and the consumption meeting of electric energy reduces greatly, and economic worth is remarkable.As, the chromium groove current consumption moon 11000KWH of month, calculates according to economize on electricity 30%, monthly can save electric energy 3300KWH, the initial stage that just can save for 1 year is built the costs that drop into more, and general a set of anode work-ing life is about 5 years, and economic benefits and social effect are remarkable;
4, because the area of anode increases, anode does not need to install additional auxiliary stereotype, and the pure degree of plating solution is greatly improved, and electroplating quality also can correspondingly improve, and surface imperfection can reduce in a large number, and has saved stereotype.
