A liquid groove is divided into a liquid conductive slot (2) and an oxidation slot (3) by a baffle plate (1); a rubber roll (4) is arranged on the upper end of the baffle plate (1); a rubber roll (4) is respectively arranged on the bottom of two ends of the liquid conductive slot (2) and the oxidation slot (3); an anode plate (5) is disposed in the liquid conductive slot (2); a cathode plate (6) is disposed in the oxidation slot (3); a DC pulse power source (7) is connected between the anode plate (5) and the cathode plate (6), wherein the anode plate (5) is connected with the anode of the DC pulse power source (7) and the cathode plate (6) is connected with the cathode of the DC pulse power source (7). In the utility model, the DC pulse power source with a high frequency is equipped to produce a compact oxide film through an alkalescent solution by using a high-frequency DC pulse current, without generating a loose layer of a conventional anode oxide film; and the apparatus has the advantage of simple structure.
Description
Technical field
The utility model relates to a kind of device of producing oxide film, relates in particular to be used for the device that differential arc oxidation generates oxide film.
Background technology
The CTCP version is made of aluminium plate base, alumina layer and photosensitive layer, before painting photosensitive liquid, carry out pre-treatment to aluminium sheet, comprises electrolytic graining, anodic oxidation and 3 steps of sealing of hole.Anodic oxidation has generated the aluminium sesquioxide of thick about 1u, and this material can make the surface of electrolytic graining have that one deck is hard, corrosion resistant protective layer, has protected Grains not to be damaged, and improves the pressrun of plate when printing.At present, the mode of known formation oxide film is to generate by continuous galvanic effect with sulphuric acid soln.This oxide film is made up of the tight zone of bottom and the tectorium on upper strata, there are a large amount of micropores to lead directly to tight zone on the tectorium, cause the wear resistance of this oxide film and erosion resistance to descend on the one hand, on the other hand in order to guarantee the pressrun of plate, need thicker oxide film, cause energy consumption higher.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of device of differential arc oxidation CTCP version of CTCP version oxide film wear resistance, good corrosion resistance of production.
The technical solution of the utility model is as follows: a kind of device of differential arc oxidation CTCP version, comprise liquid tank, described liquid tank is divided into liquid conduction groove and oxidation trough by dividing plate, described dividing plate upper end is provided with rubber roll, described liquid conduction groove and oxidation trough two ends bottom land are provided with a rubber roll, be provided with positive plate in the described liquid conduction groove, be provided with negative plate in the described oxidation trough, its key is: be connected with direct current pulse power source between described positive plate and the negative plate, wherein said positive plate connects the positive pole of direct current pulse power source, and described negative plate connects the negative pole of direct current pulse power source.Connect direct current pulse power source on the cathode-anode plate, form the loop, high-voltage and big electric current and the weakly alkaline working fluid one formation micro-arc oxidation films that works, this oxide film is thin, fine and close, wear-resisting, corrosion-resistant.
The top of aforesaid liquid conductive trough and oxidation trough outer end also is provided with rubber roll.Rubber roll is as the deflector roll of aluminium plate base.
Be provided with the jet pipe and the return line that are in communication with the outside in aforesaid liquid conductive trough and the oxidation trough.Jet pipe sprays into weakly alkaline solution in liquid conduction groove and the oxidation trough, and liquid conduction groove and oxidation trough flow out via return line and form recycle.
Beneficial effect: the utility model is installed direct current pulse power source, utilizes high-frequency dc pulse current, by weakly alkaline solution, reaches the purpose of producing fine and close oxide film.When producing oxide film, can also stop the generation of common anode oxide film tectorium, but also have advantage of simple structure.
