Description
Technical field
This utility model is related to plasma cutting machine part technical field, a kind of plasma cutting machine nozzle of specific design.
Background technology
Plasma Are Cutting Machine is the machinery being processed to metal material by plasma cutting technique.Plasma cutting
It is a kind of advanced cutting process method, using the heat of high-temperature plasma electric arc metal part or the local of workpiece incision is made
Melt, and the momentum by high speed plasma discharges motlten metal to form a kind of processing method of otch.
In prior art, there is one section of taper seat in the exit of plasma cutting machine nozzle, and beam-plasma is flowing through the section
During taper seat, the flow velocity and injection direction of beam-plasma can change because of the acute variation of nozzle profile, and interfere, so as to
The stability of beam-plasma is reduced, the cut quality of cutting machine is reduced；Simultaneously the degrees of expansion of nozzle is as beam-plasma
The change of intensity and there is acute variation, shorten nozzle service life.
The Chinese utility model patent of Publication No. CN203316895U disclosed a kind of plasma on December 4th, 2013
Cutting nozzles, including nozzle upper body and nozzle lower body, tubular structure of the nozzle lower body in both ends open, the nozzle upper body
In cone structure, the bottom internal diameter of the cone structure is identical with the internal diameter of the nozzle lower body, and the bottom of the cone structure
End is connected with one end of the nozzle lower body, and the top of the cone structure is provided with an air stream outlet, the female cone
Face is curved surface.The utility model by internal conical surface by being set to curved surface, it is to avoid direction when beam-plasma flows through nozzle occurs
Violent change, so as to improve the stability of beam-plasma and the cut quality of CUT, and extends making for shower nozzle
Use the life-span.
It is but the utility model has a defect, i.e., simply simple that nozzle head inner surface is designed as into curved surface, Zhi Nengti
Stability on the outside of higher ion beam, equally exists injection between the beam-plasma of center and the beam-plasma of marginal position
Direction and the difference of jet velocity, still suffer from turbulent flow and are formed in nozzle, so the raising of its article on plasma beam stability has
Limit.
The content of the invention
It is unstable for beam-plasma present in prior art, the low defect of cut quality, this adaptation is new to be disclosed
A kind of plasma cutting machine nozzle, what this utility model can be stable ejects beam-plasma, improves cutting for CUT
Cut quality.
This utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of plasma cutting machine nozzle, including mouth body and the conical nozzle head that is connected with mouth body, conical nozzle head
On be provided with spout, it is characterised in that：Deflector is provided with the conical nozzle head.
At least three deflectors are evenly distributed with the conical nozzle head, and the installation site of deflector is with regard to circular cone
Shape nozzle head axis of symmetry is symmetrical.
The deflector is and conical nozzle head inner surface identical arc, and with table in corresponding side conical nozzle head
Face inclines identical angle.
The deflector and conical nozzle head are formed in one structure.
The inner surface of the conical nozzle head is curved surface.
Compared with prior art, this utility model has the advantages that：
1st, this utility model is provided with deflector in conical nozzle head, by deflector to flowing through conical nozzle head
Beam-plasma carry out rectification, it is to avoid beam-plasma forms turbulent flow in nozzle because of the mutation in speed and direction, affect etc. from
The stability of beamlet, improves the cut quality of CUT, and the beam-plasma of Simultaneous Stabilization is also beneficial to improve nozzle
Service life.
2nd, at least 3 deflectors are evenly distributed with conical nozzle head of the present utility model, and the installation position of deflector
Put symmetrical with regard to conical nozzle head axis of symmetry, make the air-flow in deflector exit uniform, improve the steady of plasma (orifice) gas beam
It is qualitative.
3rd, deflector of the present utility model be in and conical nozzle head inner surface identical arc, and with corresponding side cone
Nozzle head medial surface keeps identical angle of inclination, makes deflector and conical nozzle head inner surface keeping parallelism, it is to avoid wait from
There is acute variation in beamlet airflow direction when deflector is flowed through, improve the stability of beam-plasma and the cutting matter of cutting machine
Amount.
4th, deflector of the present utility model and conical nozzle head are formed in one structure, improve stablizing for deflector connection
Property, it is to avoid the prolonged high-temperature heating fractures of junction Jing, in turn resulting in deflector comes off or connects loosely, affects beam-plasma
Stability.
5th, conical nozzle head inner surface of the present utility model is curved surface, improves the smoothness of inner surface, reduces inner surface
The angle changing of corner, enables what beam-plasma more smoothed out to flow through conical nozzle head, it is to avoid the generation of turbulent flow, improve etc.
The stability of ion beam.
