The Key Technique Of Short Electric Arc Machine Tool-the Research And Manufacture Of Electric Current Conducting Equipment

The surface-removed machining of hard machining material which has great rigidity,intensity,tenacity is a difficult problem which puzzles mechanical manufacturing.Belonging to original technique of our country,the short electric arc machining technique is a scientific,economic,high effective,low energy consumed,raw and processed materials saved,low-noise technique and becomes a rigid surface material machining technique with market potential,all right developmental foreground,high effect and utility.In this dissertation the author researches the electric current conducting system of short electric arc machine tool, which is one of the key technique of short electric arc machine tool, by taking the DHZ16040CG short electric arc machine tool as an example manufactured by Huashen electric engineering corporation and Changbai machine shop of Capital steel and iron factory, including the analysis of running characteristic of short electric arc machine tool's power supply and the working state of work piece anode and tool cathode. The author also makes a comparative analysis of every kind of electric current conducting system which is used presently, then choose one for our short electric arc machine tool, that is the carbon brush electric current conducting system, and analyses the relative ingredients which is abort the choice of carbon brush and collector ring, then chooses their specific model, in the end, the author makes a test for the choice above, which proves the correctness of academic analysis above.
