Description
Technical field
The utility model relates to tube-welding field, in particular to a kind of online gas shield device of welded tube welding seam.
Background technique
When producing pipe with welding, bending need to be formed to band and then weld.But due to welded tube
Welding carries out at high operating temperatures, therefore the weld seam for just having completed welding needs the process an of High temperature diffusion and the time comes
Further improve the quality of weld seam；In addition the weld seam under the condition of high temperature once encounters the oxygen in air, and surface will generate oxidation
Phenomenon, the oxidation of weld seam also will affect the quality of weld seam or even the use of welded tube other than the appearance for influencing welded tube
Service life.
Application No. is the Chinese patents of CN2010205434358: a kind of online gas shield of welded tube welding seam and cooling device,
Air inlet pipe is arranged in technical solution connecting copper pipe after welding booth on copper pipe, and air inlet pipe connects protective gas feeding mechanism,
Spray tube is set in copper pipe end, taps into water pipe on spray tube, water inlet pipe is connected to the aperture on inner wall, the technical solution exist with
Lower defect: welded tube needs the copper pipe entered outside welding booth just to can be carried out cooling, and welded tube has oxidation risk in moving process, no
It can quickly cool down.Protective gas needs just to be able to achieve the purpose of protection full of entire pipe and welding booth simultaneously.It fills
The gas time is long, and dosage is also more.
Utility model content
In view of this, the utility model embodiment provides a kind of online gas shield device of welded tube welding seam, with a small amount of
Protection gas makes the weld seam of welded tube completely cut off air, avoids oxidation, so that welded tube is obtained timely, rapidly cooling effect, after being
Continuous process improves working condition, is the raising of weldquality, lays a good foundation.
The utility model discloses a kind of online gas shield device of welded tube welding seam, including copper pipe, and one end of the copper pipe is deep
Enter to weld in case, the other end of the copper pipe is located at outside welding case, and the end that the copper pipe is located in welding case abuts welding gun, institute
It is hollow to state copper pipe, welded tube passes through copper pipe, and the copper pipe is equipped with spray apertures close to the side of welding gun, and the upper end of the spray apertures is equipped with
Air inlet, the air inlet upper end connective protection gas, the air inlet and sealing copper pipe.
Further, the internal diameter of the copper pipe is 3mm bigger than the outer diameter of welded tube.
Further, the spray apertures are equipped with multiple, and the spray apertures are equipped with 3 rows.
It further, is 150mm at a distance from the spray apertures nearest with welding gun and welding gun.
Further, the air inlet covers all spray apertures, and the top of the air inlet is connected to protection gas, described
The top of air inlet is located in welding case.
The utility model in welding case, can be cooled down a part setting of copper pipe at once after tube-welding,
The utility model is directly cooled down using protective gas Welded Pipe, and the weld seam of welded tube is made to have completely cut off air, is avoided oxidation, is made
Welded tube obtain in time, rapidly cooling effect.
Detailed description of the invention
Fig. 1 is an embodiment of the present invention main view.
Fig. 2 is an embodiment of the present invention top view.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the utility model a part of the embodiment, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without creative efforts
The every other embodiment obtained, fall within the protection scope of the utility model.
As Figure 1-Figure 2, the utility model discloses a kind of online gas shield device of welded tube welding seam, including copper pipe 1, institute
The one end for stating copper pipe 1 is deeply welded in case 2, and the other end of the copper pipe 1 is located at outside welding case 2, and the copper pipe 1 is located at welding case
End in 2 abuts welding gun 3, and the copper pipe 1 is hollow, and welded tube 4 passes through copper pipe 1, and the copper pipe 1 is equipped with close to the side of welding gun 3
Spray apertures 5, the upper ends of the spray apertures 5 are equipped with air inlet 6, the 6 upper end connective protection gas of air inlet, the air inlet 6 with
Copper pipe 1 seals.
A part of copper pipe is located in welding case, and the end of copper pipe abuts welding gun, is directly entered after tube-welding in this way
Copper pipe, protection gas copper pipe air inlet enter spray apertures and then act on welded tube, and Welded Pipe is cooled down.Protection gas so only needs
Full of entire copper pipe, while the internal diameter of copper pipe is little, and protection gas required for welded tube is cooling is less.Protection gas make welded tube with
Air insulated, while playing the rental of protection.
In an embodiment of the utility model, the internal diameter of the copper pipe is 3mm bigger than the outer diameter of welded tube.
In an embodiment of the utility model, the spray apertures are equipped with multiple, and the spray apertures are equipped with 3 rows.Spray apertures are used
