Embodiment 1

[0030] For the processing of large-area single-chip workpieces, the micro-arc oxidation power supply adopts a constant voltage-constant voltage control method.

[0031] Step 1. Preparation stage:

[0032] First, operate the crane control cabinet 15, move the hook 10 of the crane 4 to the workpiece 16 and the flying bus 3 to be loaded, mount the flying bus 3 on the hook 10, and hang the workpiece 16 to be processed through the clamp 11 Connect to flybar 3; make motion slider 9 at the highest position;

[0033] Secondly, operate the driving control cabinet 15, manually lift the hook 10 equipped with the flying bus 3 and the workpiece 16 in the vertical direction, move the driving 4 to the top of the electrolytic cell 5 through the driving shaft 14 in the horizontal direction, and pass the driving beam 20 to make The crane 4 descends slowly into the electrolytic cell 5 along the vertical direction until the flybar main shaft 13 rides on the arc ports of the two copper columns 9-...

Abstract

The invention discloses an anode gradual-entering type microarc oxidation treatment method with low energy consumption. Before a large-area workpiece contacts electrolyte, an electric field with voltage higher than an arcing voltage is applied to the two ends of an electrode, and constant voltage control is adopted for a microarc oxidation power supply. In the process that the workpiece is gradually soaked into the electrolyte, the speed of the workpiece to soak in the electrolyte is correspondingly regulated through detecting the consumed current of the workpiece to realize quick microarc oxidation of the surface of the workpiece. After the workpiece is completely soaked in the electrolyte, the microarc oxidation power supply finishes the microarc oxidation treatment by adopting a constant voltage, constant current or constant power control mode. The invention also discloses a device used by the anode gradual-entering type microarc oxidation treatment method with low energy consumption, and the device comprises a traveling crane, a feiba and an electrobath with an anode capable of ascending and descending. By utilizing the method and the device thereof to carry out the microarc oxidation treatment, quick film forming for large-area workpieces can be easily realized, the resource is saved, the production efficiency and the yield can be improved, and the power supply capacity can be furthest exerted.
