Description
Technical field
The present invention relates to a kind of aluminium section bar process equipment, be specifically related to the controlling party of a kind of aluminium section bar electrolytic coloring power supply
Method.
Background technology
Coloring power source is mainly used in the electrolytic oxidation coloring of aluminium section bar, carries out surface process at aluminium alloy extrusions, makes aluminium profiles
Material surface obtain shallow bronze-colored, in a kind of power supplys bronze-colored, the most bronze-colored, black, coppery, karat gold color, titanium color etc. set
Standby.The output waveform of currently used coloring power source has after pure exchange, first direct current exchange etc., and its control process is: first presoak, and connects
Output unidirectional current, then output AC electricity, until coloring terminates, if desired complementary color, then moment output AC voltage is mended
Color, then completes whole coloring process after complementary color.But traditional coloration time needs about 18 minutes, the time is longer, coloring effect
Rate is relatively low, and glossiness is inadequate, it is impossible to meet the demand that people are growing.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the aluminium section bar that a kind of coloration time is short, color glossiness is high
The control method of electrolytic coloring power supply.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of control method of aluminium section bar electrolytic coloring power supply, including following step:
Step 1, execution preimpregnation time T0；
Step 2, presoaked after, through soft start export direct-flow positive voltage, the execution time is T1；
Step 3, output after DC voltage completes, again pass by soft start output AC voltage, described alternating voltage be positive and negative not
Symmetrical alternating current voltage, described alternating voltage is sinusoidal wave form, and the absolute value of positive voltage, less than the absolute value of negative voltage, performs the time
For T2；
Step 4, complete T2 after, repeating to export step 2 and step 3, until completing periodicity N set in advance, completing coloring.
In the present invention, also including step 5, repeat N number of all after dates, instantaneous output AC voltage carries out complementary color, during execution
Between be T3.
The invention has the beneficial effects as follows: after the present invention uses first direct current, the mode of positive and negative asymmetrical alternating current controls coloring power source
Output carries out electrolytic oxidation coloring, say, that first passes through unidirectional current and is expanded by the micropore on aluminium section bar oxide-film surface, then leads to
The metal ion of positively charged is filled in micropore by the negative voltage crossing alternating current, then repeats direct current and exchanges, namely repeats
During reaming and filling, until micropore is filled.The present invention is by the way of refilling after reaming, direct with traditional
Filling mode compares, and the aperture of the present invention is big, coloring effect good, glossiness is high, and is that periodic is filled, colouring speeds
Hurry up, the time short.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the oscillogram of output voltage of the present invention；
Fig. 2 is the oscillogram of the present invention positive and negative asymmetrical alternating current voltage；
Fig. 3 is the circuit theory diagrams of the present invention.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the control method of a kind of aluminium section bar electrolytic coloring power supply that the present embodiment is provided, including with
Under several steps:
Step 1, execution preimpregnation time T0, described preimpregnation time T0 are set according to the shape of aluminium section bar, and shape is the most complicated, in advance
The leaching time needs the longest, typically can set T0 >=5s；
Step 2, presoaked after, through soft start export direct-flow positive voltage, the execution time is T1, the time of soft start be 2s～
60s, described DC voltage is 0V～21V, and the execution time is T1 >=5s；
Step 3, output after DC voltage completes, again pass by soft start output AC voltage, the time of soft start be 2s～
60s, described alternating voltage is positive and negative asymmetrical alternating current voltage, and the frequency of described alternating current is power supply frequency, described exchange
Voltage is sinusoidal wave form, and the absolute value of positive voltage, less than the absolute value of negative voltage, differs 1V～3V, performs the time between absolute value
For T2 >=5s, the generating positive and negative voltage in the voltage of described alternating current is respectively 0V～11V, and the negative value of described alternating current is more than just
Magnitude of voltage, because of metal ion positively charged, negative voltage can accelerate the metal ion of positively charged and be filled with, and shortens the filling time.
Step 4, complete T2 after, repeat to export step 2 and step 3, until completing periodicity N set in advance, described week
Issue N >=1 time, until coloring terminates, the most complicated then periodicity of shape of aluminium section bar is the highest.If need not complementary color, the most directly
Terminate, carry out next operation, if desired for complementary color, then carry out step 5.
Step 5, repeating N number of week after date, when needs complementary color, the most instantaneous output AC voltage carries out complementary color, performs the time
For T3, the value of described alternating voltage is 0V～24V, and the execution time is T3 >=1s.
The foregoing is only the preferred embodiments of the present invention, as long as realize the skill of the object of the invention with essentially identical means
Within art scheme broadly falls into protection scope of the present invention.
