Abstract

The invention discloses a cluster cathode micro-arc oxidation film preparation device and method, comprising a distance adjustment device, an electrolytic cell, a cluster cathode, a power supply and a main control computer; the distance adjustment device includes a workbench, a vertical arm, and a traverse slider and a telescopic rod, the telescopic rod is set on the traversing slider, and can be extended downward and recovered upward under the action of the ball screw transmission mechanism driven by the servo motor; the electrolytic cell is made of insulating material, placed in the working On the platform, it is used to hold the electrolyte and the workpiece to be processed; the cluster cathode is composed of several rod-shaped electrodes, and its upper end is fixed with the lower end of the telescopic rod. Or the overall micro-arc oxidation, reducing the limitation of the workpiece size on the output power of the power supply improves the effective energy utilization rate of the power supply; the arc starting area is controllable, the solution temperature is highly controllable, and the treatment cost of large surface area micro-arc oxidation is reduced.

Description

technical field [0001] The invention belongs to the technical field of micro-arc oxidation film processing equipment, and in particular relates to a cluster cathode micro-arc oxidation film preparation device and method. Background technique [0002] At present, most of the domestic micro-arc oxidation processing on the surface of the workpiece is to directly immerse the workpiece in the electrolyte as the anode, and connect the electrolytic cell to the cathode of the power supply as the cathode, without any relative movement between the cathode and the anode, and realize the surface of the workpiece after power on Simultaneous processing. This processing method is highly dependent on the power of the power supply. Due to the non-uniformity of electrical conduction and heating, there will be tip discharge and area effect on the surface of the workpiece, so the requirements for determining the processing parameters are very strict. And it is only suitable for workpieces with...
