Abstract
Content described in the invention is suitable for aviation fasteners roller for plating, relates generally to aviation fasteners product barrel plating field, and in particular to a kind of alternation formula method for plating.This method on the basis of existing technology, by changing the rotation mode of electro-plating roller, is changed to bidirectional rotation mode, effective reduction current shielding effect, to improve the galvanization coating quality uniformity and ductility of electroplated product by single rotation mode.
Description
Technical field
Content described in the invention is suitable for aviation fasteners roller for plating, relates generally to the rolling of aviation fasteners product
A kind of plating field, and in particular to alternation formula method for plating.
Background technology
In Aeronautics and Astronautics field, production, the fastener of manufacture and other hardware small parts are applicable in purpose and use according to it
Environment needs to carry out a variety of different surface treatments, and the realization of wherein exhibiting high surface coating is completed by plating mode.It should
Plating is tied up in the plating majority use of class product or barrel plating mode carries out.Currently, the domestic roller used in field of electroplating is led in cathode
The overwhelming majority is using chain conduction in electric mode, and as the cylinder rotates, part does free rotation with roller in rotation process
Turn.Ensure contact of the part with cathode in this manner, to which deposition forms coating.But the rotating cylinder mode of rolling is more
(as shown in Figure 2) is rotated clockwise for single, due to there are problems that current distribution causes product to be electroplated in electroplating process in itself
Thickness even results are unsatisfactory, so need to be adjusted on electrically conducting manner, so be in place of the innovation of the present invention by
It is single choose to install mode and change into the mode that chooses to install of alternation improve product galvanization coating uniformity.
Invention content
Goal of the invention：The present invention proposes to improve product uniformity, the maximum feature of the invention be to change and
Electro-plating roller mode after improving can reduce current shielding effect, to improve the galvanization coating quality uniformity of electroplated product
And ductility.
Technical solution：The present invention provides a kind of alternation formula methods for plating, and this approach includes the following steps：
Product is poured into roller and is rotated clockwise by step 1, rotation time T；
Step 2, after the completion of rotating clockwise, then rotated counterclockwise, rotate counterclockwise the time and rotate clockwise
Time is identical, is T, and reciprocating rotation is until plating is completed successively；
Part is poured out and dried up after the completion of step 3, plating；
Step 4 is examined by normal procedure dehydrogenation, passivation, friendship.
The drawbacks of reaching maximum solution current shielding by above technical scheme improves current distribution, adequately makes more
Product surface receives electric current to deposited plating layer.
Advantageous effects of the present invention：By the way that the implementation of this method can coating be in effective solution product electroplating process
Uniform problem makes the product rotate in same direction for a long time obtain more being in electrical contact the problem of reducing current shielding.
Description of the drawings
Fig. 1 is roller schematic diagram；
Fig. 2 is to improve front roll to rotate schematic diagram；
Fig. 3 is to improve back roll to rotate schematic diagram.
Specific implementation mode：
By taking certain bolt product barrel plating zinc implementation process as an example, its step are as follows：
1, product is poured into roller shown in Fig. 3 and is rotated clockwise 2 minutes；
2, carry out rotating counterclockwise 2 minutes after the completion of rotate clockwise by Fig. 3, later cycle rotation, until being electroplated
At；
3, part is poured out and dried up after the completion of being electroplated；
4, it presses normal procedure dehydrogenation, passivation, hand over inspection.
Pass through embodiment of above so that bolt product barrel plating zinc there are following advantages compared with the prior art：
(1) current shielding effect caused by reducing individual event rotation；
(2) increase the electrical contact probability for rotating backward rear identical parts, increase galvanic contact area；
(3) thickness evenness after product plating is improved, the single increase tendency of the coating after one-directional rotation is avoided；
(4) utilization rate of unit quantity of electricity is improved.
Claims (1)
1. a kind of alternation formula method for plating, which is characterized in that include the following steps：
Product is poured into roller and is rotated clockwise by step 1, rotation time T；
Step 2, after the completion of rotating clockwise, then rotated counterclockwise, rotate counterclockwise the time and rotate clockwise the time
It is identical, it is T, reciprocating rotation is until plating is completed successively；
Part is poured out and dried up after the completion of step 3, plating；
Step 4 is examined by normal procedure dehydrogenation, passivation, friendship.
