Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] Such as figure 1 An electrolyte plasma polishing power supply system and control method are shown. Divided into the following five modules. The power module adopts a combination of full-bridge high-frequency switch modules to convert the AC voltage input from the grid into a DC voltage. The frequency of the changeover switch is 20kHz; the voltage amplitude adjustment range is 150V~500V, and the rated capacity is 100KW. The purpo...

Abstract

The invention relates to the technical field of metal material surface treatment, specifically to an electrolyte plasma polishing power supply system and control method thereof, and the system provides pulsation power for metal surface treatment. The power supply system comprises a monitoring module, and a power module, a heat exchange module, a filter module and a modulation module which are connected in sequence, wherein the monitoring module is electrically connected with the rest of modules. The electrolyte plasma polishing power supply system solves the problems existing in the prior art that when a direct current power supply is adopted to supply power, the fault rate is high, the efficiency is low and the process quality is not easy to control. Through adoption of a medium phase-change heat exchange technology, the work efficiency and reliability of the power supply are improved; through setting of appropriate capacitance and inductance parameters, negative influence of surge current on the power supply and a power grid is inhibited, and surge current required by a polishing process is provided at the same time; and through the arrangement of the modulation module between the filter module and polishing equipment, pulsation polishing is realized. The power supply system remarkably improves processing efficiency and process quality, and also saves energy and reduces consumption, thereby generating relatively large economic benefits.

Description

Technical field [0001] The invention relates to the technical field of metal material surface treatment, in particular to an electrolyte plasma polishing power supply system and a control method thereof. Background technique [0002] The metal parts to be processed are placed in the electrolyte solution to form a gas film on the surface, and the surface is leveled by discharge and chemical reaction under the action of the electric field, so that the surface of the part reaches the required roughness. This method is used for the surface treatment of metal parts. It can complete the processes of deburring, removing oxide layers, cleaning welds, polishing, etc., instead of mechanical (manual) and chemical methods, it is not only efficient, good quality, but also easy to realize automatic continuous processing. At the same time, it greatly reduces processing costs, eliminates dust pollution, and solves pollution problems and safety hazards in mechanical and chemical processes. [0003...
