Abstract

The utility model discloses a plating tank for producing foam nickel, including a tank body, transmission roller, conductive transmission roller, anode plate, motor and reducer. The axis centers of a plurality of conductive transmission rollers are on the same horizontal line. In the electroplating process of a product, the sine-shaped trend shows, and the bending degree and crack of the product is reduced compared with the V-shaped plating tank; the contact area between the conductive transmission roller and the product is big, so the resistance is small and a heavy current is supplied to increase the plating speed. The upper and lower anode plates are arranged in a malposition manner, and thus the total electric flux of every point in the upper, middle and lower layers is basically the same as the integrated effect when the product passes by the upper and lower anode plates, increasing the uniformity of the thickness of the product.

Description

The plating tank of continuous production foaming nickel

The utility model relates to a kind of plating tank.Specifically refer to a kind of plating tank of producing foaming nickel.

The plating tank of existing continuous production foaming nickel, adopt the V-arrangement plating tank, V-arrangement plating tank live roll divides upper and lower two rows, and the foaming nickel strap bends V-shaped tendency and advances on each live roll, upper and lower in addition positive plate takes alignment thereof to arrange, there is following defective in this plating mode: 1, and the V-arrangement tendency, foaming nickel bending degree is big, make the V-arrangement plating tank can not be too big, otherwise product be easy to generate crackle to electricity.2, foaming nickel is little with conduction live roll contact area, resistance is big, electroplating current is little, electroplating velocity is slow.3, the upper and lower flush arrangement of positive plate makes the product internal layer lack the thickness direction lack of homogeneity than outer sedimentary nickel.

When the utility model purpose provided a kind of plating, foaming nickel bending degree was little, and product is not easy to crack; Foaming nickel and the conductive rollers contact area is big, resistance is little, electroplating current is big, electroplating velocity is fast.Each continuous production foaming nickel plating tank of the product of producing to good uniformity.

The utility model purpose is achieved like this, this produces the plating tank of foaming nickel, comprise cell body, frame, conduction live roll, live roll, positive plate, motor, speed reduction unit, live roll, conduction live roll are driven by speed reduction unit by motor, and the foaming nickel strap is on each live roll, and the axle center of a plurality of conduction live rolls is on same sea line.

The upper and lower positive plate of this production foaming nickel plating tank takes dislocation to arrange.

Because the axle center of a plurality of plating live rolls of the plating tank of this production nickel foam is on same sea line, product is in electroplating process, be ∽ shape tendency, relatively the V-arrangement plating tank has reduced the bending degree of product, thereby has reduced the product crackle, improve the quality of products, and ∽ shape tendency conduction live roll is big with the product contact area, thereby resistance is little, can supply with bigger electric current and make the electroplating velocity raising.Upper and lower positive plate takes dislocation to arrange.Product through on positive plate at present layer strength of electric field minimum, centre take second place, the upper strata maximum; And product is during through following positive plate, and take second place in upper strata strength of electric field minimum, centre, lower floor's maximum.When product was through upper and lower positive plate like this, net effect was every total displacement flux basically identical of each layer of upper, middle and lower, thereby has increased the homogeneity of product at thickness direction.

The utility model is described in further detail below in conjunction with accompanying drawing.

The plating tank structural representation of Fig. 1 continuous production foaming nickel

Plating tank with reference to Fig. 1, continuous production nickel foam, comprise cell body 8, live roll 11, conduction live roll 9, positive plate 1,10, motor, speed reduction unit, live roll 11, conduction live roll 9 are driven by speed reduction unit by motor, conduction live roll 9 is as negative electrode, foaming nickel strap 3 is advanced by 9,11,13 drives on each live roll, and the axle center 2 of a plurality of conduction live rolls 9 has sustained height H on same sea line.A plurality of conduction live rolls 9 can be the round rollers with diameter or different diameter, and upper and lower positive plate 1,10 takes dislocation to arrange.Foaming nickel strap 3 is in electroplating process, be ∽ shape tendency, compare the V-arrangement plating tank, reduced the bending degree of foaming nickel strap 3, thereby reduced the product crackle, improved the quality of products, and conduction live roll 9 is big with foaming nickel strap 3 contacts area, thereby resistance is little, can supply with bigger electric current electroplating velocity is improved.Upper and lower positive plate 1,10 takes dislocation to arrange.Foaming nickel strap 3 through on during positive plate 1 lower floor's strength of electric field minimum, centre take second place, the upper strata maximum; And foaming nickel strap 3 is during through positive plate 10 down, and take second place in upper strata strength of electric field minimum, centre, lower floor's maximum.The upper and lower positive plate of foaming nickel strap 3 processes is 1,10 o'clock like this, and net effect is every total displacement flux basically identical of each layer of upper, middle and lower, thereby has increased the homogeneity of foaming nickel strap 3 at thickness direction.The one or more thickening plating tanks of serial connection behind the plating tank of foaming nickel.The thickening plating tank is seated on the frame 7, thickeies plating tank by cell body 12, upper and lower positive plate 4,6, conduction live roll 13, and pressure roller 5 is formed.Foaming nickel strap 3 here coating is further thickeied to meet the requirements of area density.

The utility model is applicable to the plating of various foaming nickel, foam copper, foaming sheet iron strip.
