Below, reference picture 2, Fig. 3, Fig. 5, the structure to the characteristic of the wire electric discharge machine 100 of embodiment are carried out
Explanation.As shown in figure 3, in the top guide pad 41 of top line electrode guide part 40, being formed with and being communicated to lower side guide piece 44b's
The attraction path 41a of downside.Path 41a is attracted to be connected with attractor 48.Attractor 48 attracts the air in line electrode path.
In addition, as shown in Fig. 2 being connected in the setting of top guide pad 41 of top line electrode guide part 40 with jet nozzle 45
Nozzle passage 98, nozzle passage 98 connects via switching valve 97 with the liquid pump 96 that makes working fluid be sprayed from jet nozzle 45
Connect.Liquid pump 96 attracts working fluid from processing liquid bath 99.In addition, nozzle passage 98 via switching valve 97 with from top wire guiding nipple
43 downside attracts the attractor 95 of the air in line electrode path to connect.In addition it is also possible to make attractor 95 via switching valve
And be connected with the attraction path 41a shown in Fig. 3, it is used for attracting path 41a attraction and the attraction of nozzle passage 98.
Between upper side guide piece 44a and top power part 42, the part in the gap as filling between the two is configured with
Secondary guide 47a.Between lower side guide piece 44b and top wire guiding nipple 43, the gap between the two as filling is configured with
Part adapter 47b.Due to being configured with the part in filling gap, therefore line electrode is being attracted to lead to using attractor 48,95
During air in road, the air of the outside of path will not be attracted and cause attraction efficiency reduction.
Make attractor 48,95, the pulse electric (not shown) that is rotated liquid pump 96, switching valve 97, feed rolls 21
Machine, by air be fed through guiding tube head 32 air pump (not shown) carried out by the NC devices 90 of wire electric discharge machine 100
Control.
As shown in figure 5, if NC devices 90 send wiring instruction, control unit 92, which is started, makes what feed rolls 21 were rotated
Pulse motor (not shown), by air be fed through guiding tube head 32 air pump (not shown) and attractor 48.In wiring
During beginning positioned at the bottom of top guiding tube 31 line electrode 1 leading section by feed rolls 21 make its feed (feeding during wiring
Speed：Side guide piece 44a is approached 5000mm/min) and upwards.
Now, because the air mass flow and the air mass flow of the attraction of attractor 48 for making to supply from guiding tube head 32 are in flat
Weighing apparatus, therefore the leading section of line electrode 1 passes through upper side guide piece 44a, and the air blown out from top guiding tube 31 will not go out in pipe
Mouthful (that is, upper side guide piece 44a) rebounds, and in top guiding tube 31 air will not convection current and hinder the feeding of line electrode 1.
Judging part 91 judges the position of the leading section of line electrode 1 according to the rotation amount (line electrode sendout) of feed rolls 21
Put, if the leading section of line electrode 1 reaches supreme side guide piece 44a, control unit 92 is sent and instructed, stop attractor 48
Attract, start the attraction carried out by attractor 95, the air in line electrode path is attracted from the downside of top wire guiding nipple 43.This
When, the rotation of feed rolls 21 is set to low speed or stopping.
Since (starting) the attraction carried out by attractor 95 after the set time, stopping is carried out by attractor 95
Attraction, switching valve 97 is switched over and is connected liquid pump 96 with nozzle passage 98, start to nozzle passage 98 supply plus
Work liquid, and feed rolls 21 is rotated and is sent out line electrode 1.Liquid pump 96 attracts working fluid from processing liquid bath 99.From jet
The working fluid that nozzle 45 sprays sprays downwards from top processing nozzle for liquid 46, attracts line electrode 1 and it is fed downwards, makes
Its leading section starts Kong Erxiang bottoms line electrode guide part 60 by the processing of machined object 51 and fed.
The position of the part 62 if leading section of line electrode 1 powers to the bottom for reaching lower line electrode guide part 60, not
The sensor of diagram is detected to the situation, and detection signal is sent to the judging part 91 of NC devices 90.Judging part 91 judges
The position of the leading section of line electrode 1, is sent to control unit 92 and instructs, and stopping is supplied from what liquid pump 96 was carried out to jet nozzle 45
Working fluid.
If the leading section of line electrode 1 is electric through bottom line electrode guide part 60, bottom line electrode feeding portion 70 and line
Pole recoverer 80 and sandwiched by line recycling roll 81a, 81b, then due to line recycling roll 81a, 81b line electrode feed speed than feeding
The feed speed of roller 21 is fast, therefore the rotating speed increase by pulling of feed rolls 21.91 pairs of situations of judging part of NC devices 90 are carried out
Judge, send and transport completion instruction, after fixed free time, releasing wiring instruction and transporting completion instruction, terminating
The automatic connection operation of a series of line electrode 1.
The wire electric discharge machine 100 of embodiment from the description above, is oriented to due to being provided with from top line electrode
The lower side guide piece 44b in portion 40 downside attracts the attractor 48 of air, therefore, it is possible to make superfine line electrode 1 pass through upper lines
Electrode guide part 40.
