The present invention relates to a device and method of plasma polishing stainless steel wire which move a stainless steel substrate of a polished metal wire to soak in negative-electrode polishing solution of each accommodation tank, thus continuously plasma polishing the stainless steel substrate of the polished metal wire.
A conventional method of plasma polishing flexible metal wire contains steps of: connecting a predetermined section of 5 m to 6 m of a polished metal wire with positive electrode of electric current; and soaking the predetermined section of the polished metal wire in negative-electrode polishing solution of each accommodation tank so as to plasma polish the predetermined section of the polished metal wire in electric field.
However, this conventional method cannot continuously plasma polish the polished metal wire when the polished metal wire is long.
To solve above-mentioned defects, the waves are applied to generate the electricity currently, yet it destroys power generation facilities easily. Furthermore, as fixing a conventional wave power generator on a ship or on a seabed, cables transmit the electricity in a long time and at limited quantity.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a device and method of plasma polishing stainless steel wire which move a stainless steel substrate of a polished metal wire to soak in negative-electrode polishing solution of each accommodation tank, thus continuously plasma polishing the stainless steel substrate of the polished metal wire.
Another objective of the present invention is to provide a device and method of plasma polishing stainless steel wire in which multiple electric insulation structures are respectively mounted beneath bottoms of each accommodation tank, the supply segment, the rolling segment, the first cleaning tank, and the second cleaning tank so that when the polished metal wire is plasma polished, each accommodation tank electrically insulates from an exterior environment.
