Description
Technical field
The present invention relates to a kind of plasma cutting gun.
Technical background
In plasma cutting process, the electrode being connected with power cathode is wearing detail.Because pass through in the process of cutting
The hafnium filament being fixed on electrode, electric arc is sprayed, electric arc forms plasma arc under voltage, air pressure, magnetic fields and cut, so
And be easy to occur in real work after hafnium filament exhausts, the situation that electrode burns away, the electrode being depleted produces impurity, and with
Cooling water is discharged.
A backwater channel is provided with cutting gun at present, inside and outside the backwater channel UNICOM electric conductor, passes through electric conductor
Interior backwater hole directly discharges cooling water, and such way causes the backwater through hole in electric conductor easily to block, because of electric conductor
It can not be repaired once blocked, cutting gun can only be changed, brought substantial amounts of fund and waste.
The defects of existing in view of above-mentioned existing plasma cutting gun, the present inventor are based on being engaged in such product design system
Abundant for many years practical experience and professional knowledge are made, and coordinates the utilization of scientific principle, is actively subject to research and innovation, to found one kind
New plasma cutting gun, it is set to have more practicality.
The content of the invention
The present invention provides a kind of plasma cutting gun, and impurity can be concentrated to the junction of wearing detail electrode, make its
Cleared up during changing electrode, extend the service life of cutting gun, improve efficiently current cooling water circulation mistake
Cheng Zhong, fund caused by cutting gun is changed because of channel blockage and is wasted.
Technical scheme provided by the invention is as follows：A kind of plasma cutting gun, including electric conductor and electrode, both at interior
The hollow rotary body in portion；Electric conductor bottom is wrapped in electrode upper periphery, and both are connected through a screw thread, and in electric conductor and electrode
Threaded connection place be provided with through hole, the through-bore axis weight on the electric conductor and electrode respectively after position both is connected to
Close, form the first backwater channel.
Further, axis of the axis of through hole perpendicular to electric conductor.
Further, the junction of electric conductor and electrode is provided with least one the first backwater channels, and when described first
When backwater channel quantity is more than 1, the axis on the electric conductor is uniformly distributed.
Further, a diameter of 0.2~6mm of through hole.
Further, plasma cutting gun also includes insulating cylinder, and insulating cylinder is wrapped in electric conductor periphery, and with the conductive bodily form
Into closed cavity.
Further, intake tunnel and the second backwater channel are provided with electric conductor, cooling water is sent into electricity by intake tunnel
Extremely interior, the second backwater channel exports the cooling water flowed into cavity；Intake tunnel, the first backwater channel and the second backwater channel
Form cooling water circulation passage.
After employing above-mentioned technical proposal, the present invention has following beneficial effect：
1st, cooling water is in reflux course, and during by the first backwater channel, because water (flow) direction changes, impurity can lead in electrode
The upper surface in hole obtains a resistance, therefore is easier to deposit here.
2nd, because electrode be wearing detail, the certain time that often works just needs to change, change when will can be deposited on electrode and
The impurity of electric conductor junction cleans out together, protects electric conductor, effectively solves the problems, such as that electric conductor is blocked.
The 3rd, multiple less first backwater channels in aperture are set, first, the cleanup area to impurity is expanded, it is effective right
Short grained impurity is cleared up, second, even if when the backwater channel of part first therein blocks, cutting gun can also be after
Continuous normal work.
Brief description of the drawings

Embodiment
In order that those skilled in the art more fully understand the technical scheme in the present invention, below in conjunction with of the invention real
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described implementation
Example only part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, should all belong to protection of the present invention
Scope.
The embodiment of the present invention is write by the way of progressive.
As shown in figure 1, the present embodiment provides a kind of plasma cutting gun, including electric conductor 1, electrode 2, the bottom of electric conductor 1
The top peripheral of electrode 2 is wrapped in, both are connected through a screw thread, and are provided with the threaded connection place of electric conductor 1 and electrode 2 logical
Hole, the through-bore axis on electric conductor 1 and electrode 2 overlaps respectively after position both is connected to, and forms the first backwater channel 3,
Axis of the axis of through hole perpendicular to electric conductor 1, so that cooling water is in reflux course, and water (flow) direction changes, impurity meeting
A resistance is obtained in the upper surface of the through hole of electrode 2, it is easier to is deposited here.
A diameter of 1.5mm of through hole, the first backwater channel 3 in the present embodiment have 6, and on the axle of electric conductor 1
Line is uniformly distributed.For through hole for the backwater hole of electric conductor in existing design, diameter is smaller so that smaller diameter scope
Impurity is blocked, and sets a plurality of first backwater channel 3, even if when the first backwater channel of part 3 therein blocks, cutting gun is also
Normal work can be continued.
