Further optimize above-mentioned technical proposal, because line electrode 1 is back and forth movement, after every bout discharge loss, can
Pass sequentially through coating unit 2 and solidification equipment 3 rebuilds the conductive coating layer 13 of loss, therefore, the silk cylinder 4 on returning to of line electrode 1
Also need to, by coating unit 2, be also possible to that conductor fluid 12 can be coated with thereon before, it is conductive if do not processed it
Fluid 12 is difficult to secure on line electrode 1, and line electrode 1 easily brings the conductor fluid of liquid into silk cylinder, causes to waste, or even have
Potential safety hazard, in order to avoid above mentioned problem, in embodiments of the present invention, coating unit 2 is the tank for being contained with conductor fluid 12,
The through hole for being available for line electrode 1 to pass through, through hole of the tank away from the side of solidification equipment 3 are offered on two relative side walls of tank
Micro- with line electrode 1 to be engaged, through hole and the gap of line electrode 1 near the side of solidification equipment 3 coordinate.By making tank away from solid
Makeup put 3 sides through hole it is micro- with line electrode 1 be engaged, the conductor fluid on line electrode 1 can be wiped off, it is to avoid its drip
Fall, at the same avoid its adhere to silk cylinder 4 on, and on tank near solidification equipment 3 through hole due to the distance of solidification equipment 3 compared with
Closely, after line electrode 1 passes through from through hole, conductor fluid thereon can be quickly solidified to form in the presence of solidification equipment 3 leads
E-coat 13, therefore, the appropriate expansion of the through hole of the side can be passed through in order to line electrode 1；Coating unit 10 is filled with coating
Put 2 identical, conductor fluid can be avoided to adhere on lower silk cylinder 5.
Certainly, in addition to above-mentioned passive type coating unit 2, can also be coated on line electrode 1 by the way of active
Conductor fluid 12, such as can be by the way of spraying.
The optional wide range of conductor fluid 12, those skilled in the art can be selected as needed, such as, and electrical conduction current
The main body of body 12 is conductive silver paste, conductive copper paste, conductive carbon paste or electrically conductive ink, and auxiliary body is light curing agent, conductor fluid 12
Material it is different, property is different, and its curing mode is also required to be adjusted correspondingly, such as, can be using ventilation unit in normal temperature
Under solidified, or, solidified using ultraviolet curing device or the device that is heating and curing.
In order to ensure being normally carried out for electro-discharge machining, in process, it is necessary to carry out feed flow to machining area and wash away
Chip removal, therefore, in embodiments of the present invention, selfreparing line electrode spark cutting device also includes being used to be supplied to machining area
The work liquid supply unit of working solution.
Work liquid supply unit is mainly used in providing working solution to machining area to play a part of feed flow and wash away chip removal,
Therefore, in embodiments of the present invention, work liquid supply unit is included for holding the liquid bath 16 of working solution, for extracting working solution
Delivery pump 15 and with the conveying nozzle 14 that is connected of pump output terminal.Certainly, the structure of work liquid supply unit is not limited only to
Structure is stated, those skilled in the art can be adjusted as needed, as long as feed flow can be played to machining area and chip removal is washed away
Effect, the embodiment of the present invention do not limit.
Further optimize above-mentioned technical proposal, it is only lateral to be processed from one when workpiece to be processed 8 has certain thickness
Supply working solution on workpiece 8, may due to working solution cannot rapid Cover machining area, cause feed flow and to wash away chip removal too late
When, effect is poor, therefore, in embodiments of the present invention, nozzle 14 is provided with two, respectively from the both sides up and down of workpiece to be processed 8
