Description
Technical field
The utility model belongs to plasma beam surface processing technology field, is related to a kind of suitable for the processing of small-sized bore area
Plasma gun.
Background technology
As the beam-plasma of one of three big high energy beams, play the part of emphatically in fields such as the cuttings and surface treatment of metal material
Act on.Beam-plasma equipment is generally made of power supply, pipette tips, control system, air supply system and water-cooling system.Due to plasma
Two electrodes, gas passage and cooling water circulation passage are integrated with the same time inside beam pipette tips, causes it often complicated, volume
It is difficult to reduce, and then the use for making it be difficult to be suitable under some operating modes for requiring pipette tips volume or height, such as diameter
Less bore area processing etc..
The content of the invention
The utility model proposes a kind of beam-plasma pipette tips, the pipette tips are by using special cooling water passage structure and send
Gas mode, considerably reduces the height of pipette tips, improves the working ability of beam-plasma.
The utility model proposes beam-plasma pipette tips by outer tube, inner tube, nozzle, tungsten electrode, tungsten electrode installing pipe, water stream
Pipe, and auxiliary supports composition.For its middle external tube as the body of a gun, tube wall is provided with the access opening of nozzle mounting hole and Inlet and outlet water.Spray
Mouth is installed on nozzle mounting hole.Inner tube is T-shaped pipe, and as gas passage, its trunk is placed in outer tube, it is parallel with outer tube but
Do not contact, the port closed close to nozzle one end, T-shaped branched pipe and outer tube nozzle mounting hole are concentric.T-shaped branched pipe and nozzle it
Between using auxiliary supports fill.Tungsten electrode installing pipe is located in T-shaped branched pipe, and tungsten electrode is installed in tungsten electrode installing pipe, tungsten electrode with
Gas passage is left between tungsten electrode installing pipe, and tungsten electrode is neither contacted with tungsten electrode installing pipe with nozzle.The both ends of outer tube are by aiding in
Supporting item separates outer tube and inner tube and positions, while closing water cooling region is formed between inner and outer pipes.Water flow diversion pipe is reducing
Insulation tube, is placed between inner and outer pipes, and maximum gauge is equal to outer tube wall diameter, and minimum diameter is more than outer wall of inner tube diameter, maximum
Diameter end is connected with outer tube wall, between two exhalant canal holes, is extended afterwards to the T-shaped branch's pipe end of inner tube.
In use, the external pipe connection power anode of pipette tips, tungsten electrode connect power cathode.Water stream between outer tube and inner tube
Pipe is separated out cooling water channel.Ion-gas then enters from inner tube one end, is reached by the gas passage between tungsten electrode installing pipe and tungsten electrode
At nozzle.After powering on, plasma arc is produced between nozzle and tungsten electrode first, then produced between tungsten electrode and anode workpiece etc.
Ion arc, realizes that beam-plasma is processed.
Compared with beam-plasma pipette tips common at present, the described pipette tips of the utility model have the advantage that：
1st, pipette tips volume low height is low, is adapted to the more harsh operating mode of size condition；
2nd, the direct contact nozzle of water-cooling system and cathode inner tube, have good cooling effectiveness, in the case of guarantee is high-power
Stable operation.
Patent CN203484793U proposes the plasma arc powder surfacing rifle suitable for aperture, by varying welding gun pipeline
It is laid out to compress the height of gun body.Aqueous vapor passage annular distribution in the patent is in pipette tips so that and the reduction of its volume is extremely limited,
Water route and gas circuit and the concentric setting of the body of a gun then be have compressed into the height of gun body to a greater degree in the utility model.And this
Good cooling in utility model to tungsten electrode is also what the patent was unable to reach.It is suitable for described in patent CN104308349B
The plasma gun of aperture, can obtain low height really in theory, but its water-cooling system cannot complete the cold of tungsten electrode
But.And the rifle does not have the setting of nozzle so that after the nozzle scaling loss of vulnerable part, whole rifle can only be scrapped.It is same to make
To be cooling tungsten electrode for the patent CN106624305A of aperture built-up welding, double water-cooling systems are employed, this structure not only manufactures
Complexity, also determines that its height cannot reach the compression degree of the utility model.
