Abstract
The invention discloses a plasma cutting gun. The plasma cutting gun comprises a conductor and an electrode. The conductor and the electrode are each a hollow rotary body. The periphery of the upper portion of the electrode is wrapped by the lower portion of the conductor. The conductor and the electrode are in threaded connection. Through holes are formed in the threaded connection positions of the conductor and the electrode. After the conductor and the electrode are connected in place, the axes of the through holes located in the conductor and the electrode respectively coincide to form a first water return channel. According to the technical scheme, impurities can be centralized to the joint of the wearing part, namely, the electrode, the impurities can be removed in the electrode replacing process, the service life of the cutting gun is prolonged, and capital waste caused by cutting gun replacement due to channel blockage in the current cooling water circulation process is effectively eliminated.
Description
Technical field
The present invention relates to a kind of plasma cutting gun.
Technical background
In plasma cutting process, the electrode be connected with power cathode is wearing detail.Because in the process of cutting by being fixed on the hafnium filament on electrode, ejection electric arc, electric arc forms plasma arc cutting under voltage, air pressure, magnetic fields, but after being easy to occur that hafnium filament exhausts in real work, the situation that electrode burns away, the electrode be depleted produces impurity, and discharges with cooling water.
A backwater channel is provided with in current cutting gun, inside and outside this backwater channel UNICOM electric conductor, directly cooling water is discharged by the backwater hole in electric conductor, such way makes the backwater through hole in electric conductor very easily block, because of electric conductor once cannot keep in repair after blocking, can only cutting gun be changed, bring a large amount of fund wastes.
Because the defect that above-mentioned existing plasma cutting gun exists, the present inventor is based on being engaged in the practical experience and professional knowledge that this type of product design manufacture enriches for many years, and coordinate the utilization of scientific principle, actively in addition research and innovation, to founding a kind of novel plasma cutting gun, it is made to have more practicality.
Summary of the invention
The invention provides a kind of plasma cutting gun, impurity can be concentrated to the junction of wearing detail electrode, it is made to be cleared up in the process changing electrode, extend the service life of cutting gun, improve efficiently in current cooling water circulation process, change the fund waste that cutting gun brings because of channel blockage.
Technical scheme provided by the invention is as follows: a kind of plasma cutting gun, comprises electric conductor and electrode, and the two is the rotary body of boring; Electric conductor bottom is wrapped in electrode upper periphery, and both are threaded connection, and is provided with through hole in the threaded connection place of electric conductor and electrode, and the through-bore axis laid respectively at after the two connection puts in place on electric conductor and electrode overlaps, and forms the first backwater channel.
Further, the axes normal of through hole is in the axis of electric conductor.
Further, the junction of electric conductor and electrode is provided with at least one the first backwater channels, and when described first backwater channel quantity is greater than 1, the axis about described electric conductor is uniformly distributed.
Further, the diameter of through hole is 0.2 ~ 6mm.
Further, plasma cutting gun also comprises insulating cylinder, and insulating cylinder is wrapped in electric conductor periphery, and forms airtight cavity with electric conductor.
Further, electric conductor is provided with intake tunnel and the second backwater channel, cooling water is sent in electrode by intake tunnel, and the cooling water flowed in cavity is derived by the second backwater channel; Intake tunnel, the first backwater channel and the second backwater channel define cooling water circulation passage.
After have employed technique scheme, the present invention has following beneficial effect:
1, cooling water is in reflux course, and through the first backwater channel, because water (flow) direction changes, impurity can obtain a resistance at the upper surface of electrode through hole, therefore more easily deposits herein.
2, because electrode is wearing detail, the certain hour that often works just needs to change, and just can clean out being deposited on electrode together with the impurity of electric conductor junction, protecting electric conductor, effectively solving the problem that electric conductor is blocked when changing.
3, arrange the first backwater channel that multiple aperture is less, one is expand the cleaning scope to impurity, effectively clears up short grained impurity, even if two is that cutting gun can also continue normal work when part first backwater channel wherein blocks.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the partial structurtes schematic diagram of plasma cutting gun of the present invention;
Implication is marked: 1, electric conductor in figure; 2, electrode; 3, the first backwater channel; 4, insulating cylinder; 5, cavity; 6, intake tunnel; 7, the second backwater channel.
Detailed description of the invention
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
The embodiment of the present invention adopts the mode of going forward one by one to write.
As shown in Figure 1, the present embodiment provides a kind of plasma cutting gun, comprise electric conductor 1, electrode 2, electric conductor 1 bottom is wrapped in electrode 2 top peripheral, both are threaded connection, and be provided with through hole in the threaded connection place of electric conductor 1 and electrode 2, the through-bore axis laid respectively at after the two connection puts in place on electric conductor 1 and electrode 2 overlaps, form the first backwater channel 3, the axes normal of through hole is in the axis of electric conductor 1, make cooling water like this in reflux course, water (flow) direction changes, impurity can obtain a resistance at the upper surface of electrode 2 through hole, more easily deposit herein.
The diameter of through hole is 1.5mm, and the first backwater channel 3 in the present embodiment has 6, and is uniformly distributed about the axis of electric conductor 1.Through hole is for the backwater hole of electric conductor in existing design, diameter is less, and the impurity of more minor diameter scope is blocked, and arranges many first backwater channels 3, even if when part first backwater channel 3 wherein blocks, cutting gun can also continue normal work.
