Description
Technical field
The invention belongs to field of surface treatment, it is related in a kind of guarantee electroplating work procedure and correctly enters total current
Method.
Background technology
In Surface Processing Industry, the size of current used when part volume is electroplated is typically all first
Calculate the electric current i of single part consumption1, computational methods are that single part surface area is multiplied by current density；Again
Calculate the electric current i of single suspender consumption used2, computational methods are that single suspender surface area is multiplied by current density
Then theoretical total current value I required during groove plating is calculated, is then set according to the total current value I calculated
The input total current value on power control is put, is then hung part in tank liquor 5 using suspender,
It is initially powered up being electroplated again, until plating is finished.The problem of this way is present is 1, when theoretical total electricity
When flow valuve sets unreasonable, the input total current value I caused can not meet the technological requirement of single part 4
When current density 2, the clamping of suspender and part and in poor shape hanging, conduction state is influenceed, so as to cause
Electric current distribution is uneven..And the two problems are often not easy to discover, even if workman has found, in adjustment input
It is usually by virtue of experience, thus to easily cause that electroplating quality is unstable and waste of the energy during total current value.
The content of the invention
The purpose of the present invention is：Proposition is a kind of can constantly to monitor the current value of part in the plating process,
And, by correctly adjusting input total current value I, can reach according to monitored results and meet part electroplating technology
It is required that current density, it is ensured that electroplating quality, the method for preventing energy waste.
2nd, inventive technique solution
A kind of method for ensureing to correctly enter total current in electroplating work procedure of the present invention, concrete scheme step
It is rapid as follows：
(1) suspender is made, each suspender accesses an ammeter, suspender and ammeter one electricity of formation
Logical circulation road, the quantity of suspender is determined according to number of parts according to Principle of Average Allocation.
(2) theoretical current value i=(n required when a suspender and its plating of filled part are calculated1/n2)
×i1+i2, wherein n1For overall number of components, n2For the quantity of suspender, i1The electric current consumed for single part,
i2The electric current consumed for single suspender.
(3) theoretical total current value I=i × n required during groove part plating is calculated2。
(4) part is averagely mounted on each suspender by quantity, then by suspender hanging on conducting rod 1,
Part is set to immerse in tank liquor.
(5) the input total current value on power control is set according to the theoretical total current value I calculated,
It is initially powered up.
(6) adjust：The first step, observes the reading of the ammeter on each suspender, finds there is the electricity of suspender
The reading of flow table is more than 20% with theoretical current value i deviation range, checks clamping and the hanging of the suspender
State, can manually adjust suspender and part, it is ensured that suspender and part are in normal conducting state, pass through
After checking and manually adjusting, should ensure that the ammeter of the suspender reading and theoretical current value i deviation it is equal
No more than 20%；Second step, it is ensured that the average value of the reading of the ammeter of all suspenders and theoretical current value i
Deviation be not more than 5%, adjustment mode is：Reduce input total current value I, the electric current of suspender can be reduced
The average value of meter reading；Increase input total current value I, can increase the average value of the electric current meter reading of suspender.
(7) it is powered after adjustment is finished and proceeds plating, until plating is finished.
It is an advantage of the invention that：Part can be constantly monitored in the plating process using the method for the present invention
Current value, it is possible to input total current value is correctly adjusted according to monitored results, reaches and meets part galvanizer
The current density of skill requirement, it is ensured that electroplating quality, prevents energy waste.
Brief description of the drawings：
