Description
Technical field
This utility model is related to CUT technical field, and in particular to a kind of plasma spray of generation spiral air flow
Mouth.
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 actual production, it is exactly that cutting mouth oblique angle easily occurs that CUT has a main defect, whole
Individual cutting mouth is in the shape of the letter V, and cutting machine cutting speed is faster, and its oblique angle is bigger；This defect of cutting machine prevents it from applying
In the processing compared with high verticality is required, the use range of CUT is greatly limit.
The Chinese utility model patent of Publication No. CN203956316U disclosed a kind of new on November 26th, 2014
Plasma cutting rotating the arc generating meanss, including plasma cutting torch, drive the motor of cutting cutting torch rotation, for connecting
The gear drive of motor and cutting cutting torch, the motor drives cutting cutting torch to be rotated by gear drive.
The utility model realizes the regulation of plasma-arc rotary speed, but it has a defect, that is, cut
The rotation of torch is limited for the induced effect that beam-plasma rotates, and the effect that rotarily drives of its beam-plasma to center is compared
The induced effect of peripheral beam-plasma is weak, and meeting formation rotary speed between the outside and beam-plasma of center is poor, and then
Turbulent flow is formed in beam-plasma, the stability of beam-plasma is affected.
The content of the invention
Turbulent flow is easily formed in rotary course for beam-plasma present in prior art, the defect of stability difference,
The utility model discloses a kind of rotating plasma cutting head, can be stablized using this utility model, efficiently export rotation etc.
Ion stream, improves the quality that CUT cuts vertical incision.
This utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of plasma nozzle for producing spiral air flow, including mouth body, are provided with conical nozzle head, institute with the mouth
State and be provided with spout on conical nozzle head, it is characterised in that：Spiral air flow generator, mouth body and spiral shell are socketed with the mouth
Rolling bearing is provided between rotational gas flow generator；The spiral air flow generator is provided with the air-flow corresponding with spout and goes out
Mouthful, it is provided with deflector in the spiral air flow generator；The spiral air flow generator surface is provided with travelling gear, transmission
Gear is connected with motor.
The deflector at least two panels, deflector is uniformly distributed in spiral air flow generator.
The deflector and spiral air flow generator are formed in one structure.
The spiral air flow generator lower end is adapted with conical nozzle head, be provided with spiral air flow generator etc. from
Edema of the legs during pregnancy body sealing ring.
Anti-skid washer is provided between the spiral air flow generator and rolling bearing.
Compared with prior art, this utility model has the advantages that：
1st, spiral air flow generator is socketed with plasma nozzle of the present utility model, is provided with spiral air flow generator
Deflector, spiral air flow generator surface is provided with travelling gear, and by motor the rotation of spiral air flow generator is driven, and leads to
The agitation for crossing deflector produces spiral air flow, and the spiral air flow rotatory that it is produced is strong, can effectively improve CUT
Cut quality during cutting vertical incision, while being not likely to produce turbulent flow, stability is high, is conducive to the service life of prolonging nozzle.
2nd, at least provided with two panels deflector, deflector is uniformly distributed in spiral air flow generator this utility model；Spiral shell
Plasma air-flow is stirred by deflector when rotational gas flow generator rotates, the strength and stability of spiral air flow is improve.
3rd, deflector of the present utility model and spiral air flow generator are formed in one structure, it is ensured that deflector structure it is steady
It is qualitative, it is to avoid deflector loosens, improve the stability of plasma air-flow.
4th, spiral air flow generator lower end of the present utility model is adapted with conical nozzle head, on spiral air flow generator
It is provided with plasma (orifice) gas body sealing ring；Improve the closed type of structure, it is ensured that the intensity of plasma air-flow.
5th, it is provided with anti-skid washer between spiral air flow generator of the present utility model and rolling bearing, it is ensured that spiral air flow
Generator can firmly be connected with rolling bearing, it is to avoid spiral air flow generator comes off in high-speed rotation.
