Abstract
An outer layer air current protective spray nozzle for a high-power automatic TIG (tungsten inert gas) welding gun comprises a spray nozzle body, wherein the spray nozzle body has a hollow structure; a cavity in which a welding gun is inserted is arranged in the middle of the spray nozzle body; and a fastening piece is arranged at the upper part of the spray nozzle body. The utility model provides the outer layer air current protective spray nozzle for the high-power automatic TIG welding gun, which can effectively meet the requirements of high-power welding and prevent a protector from generating turbulent flow.
Description
Technical field
The utility model belongs to welding gun, and especially a kind of TIG welding gun outer gas flow protection nozzle can be applicable to the high-power TIG automatic welding device.
Background technology
All the time; the weldquality that adopts the TIG welding method to obtain be in the present conventional welding procedure (non-high energy beam welding procedure) of generally acknowledging preferably; and be widely used to every field; but because its welding current allowable is lower, it is lower to cause welding deposition efficiency, and operating efficiency is also comparatively low; its major technique bottleneck is the TIG welding gun; present TIG welding gun power is all big inadequately, and the argon shield air-capacitor of welding gun easily produces turbulent flow, can not adapt to the high power welding occasion.
Summary of the invention
For the protection air-capacitor that overcomes existing welding gun easily produces turbulent flow, can't adapt to the deficiency that high power welding requires, the utility model provides a kind of effective adaptation high power welding to require, avoid protector to produce the high-power automatic TIG welding rifle outer gas flow protection nozzle of turbulent flow.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of high-power automatic TIG welding rifle outer gas flow protection nozzle; described outer gas flow protection nozzle comprises nozzle body; described nozzle body is hollow structure, and the cavity that inserts for torch neck is established at described nozzle body middle part, and the top of described nozzle body is provided with securing member.
Further, the wall of described nozzle body is provided with the gas cooled passage.
Further again, described cavity is stairstepping, and the diameter of the upper cavity of described nozzle body is littler than the diameter of lower cavity, and the top of described nozzle body is provided with the assist gas passage, and described assist gas passage is communicated with described lower cavity.
Technical conceive of the present utility model is: when adopting the TIG welding method; when especially high-power TIG welds; for the better weldquality that obtains; we have increased a dismountable outer nozzle of protecting in the torch neck outside; protect gas outward for welding gun increases one deck, form two air-flow protection weld seams and heat affected area, this outer protection nozzle adopts water-cooling pattern; be more suitable for the high-power TIG welding, adopt the multiple filtration net between nozzle puff prot and the torch neck to guarantee that protection gas can turbulent flow.In addition, outer field protection gas has certain compression to electric arc simultaneously, can make arc energy more concentrated, improves arc stiffness, and this method can be extensive use of to each TIG welding field.
The beneficial effects of the utility model mainly show: effectively adapt to high power welding and require, avoid protector to produce turbulent flow, can effectively protect weld seam and heat affected area.
Description of drawings
Fig. 1 is high-power automatic TIG welding rifle outer gas flow protection structure of nozzle figure.
Fig. 2 is A-A sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2; a kind of high-power automatic TIG welding rifle outer gas flow protection nozzle; described outer gas flow protection nozzle comprises nozzle body 1; described nozzle body 1 is hollow structure; the cavity 2 that inserts for torch neck is established at described nozzle body 1 middle part, and the top of described nozzle body 1 is provided with securing member 3.
The wall of described nozzle body 1 is provided with gas cooled passage 4.
Described cavity 2 is stairstepping, and the diameter of the upper cavity of described nozzle body 1 is littler than the diameter of lower cavity, and the top of described nozzle body 1 is provided with assist gas passage 5, and described assist gas passage 5 is communicated with described lower cavity.
In the present embodiment; the torch neck outside has increased a dismountable outer protection nozzle; for increasing one deck, welding gun protects gas outward; form two air-flow protection weld seams and heat affected area; should adopt water-cooling pattern by outer protection nozzle; be more suitable for the high-power TIG welding, adopt the multiple filtration net between nozzle puff prot and the torch neck to guarantee that protection gas can turbulent flow.In addition, outer field protection gas has certain compression to electric arc simultaneously, can make arc energy more concentrated, improves arc stiffness, and this method can be extensive use of to each TIG welding field.
