Abstract
The utility model discloses a kind of circular weld reverse side air-breather, comprise air channel, described air channel inside is provided with gas block panel, in air channel outer setting, there is the vertical breather pipe being communicated with air channel, described vertical breather pipe upper end is fixed with handle, at vertical breather pipe middle part, be also provided with the horizontal communication pipe being communicated with vertical breather pipe, in described vertical breather pipe and horizontal communication pipe, be provided with air screen, on described gas block panel, be provided with some passages.The utility model is by fitting the profile of the edge of this device and parts, in inside, air screen is set, by breather pipe, protective gas is caused in groove, owing to having one in air channel with the baffle plate of passage, make gas be full of air channel, thereby make sealing run protection respond well; The utility model manufacture is simple, easy to operate, greatly reduces gas waste, and weld seam protection is effective, and workman's labour intensity is low.
Description
Technical field
The utility model belongs to welding processing technical field, relates to a kind of circular weld reverse side air-breather.
Background technology
When carrying out annular butt weld welding, back of weld need to carry out manual ventilation.When carrying out the manual ventilation of reverse side, normally adopt the cylindrical air channel of about φ 30mm to carry out artificial ventilation at present, operator need hold cylinder air-breather along with positive welding gun moves with uniform velocity, and now two people's speed is difficult to reach consistent.Because cylindrical air-breather is little; can not protect and form the weld seam not solidifying completely, simultaneously owing to fitting completely with the profile of part, cause air easily to mix with inert gas; the shaping and the protection poor effect that make sealing run cause Leakage Gas waste simultaneously.
Utility model content
For addressing the above problem, the utility model provides a kind of circular weld reverse side air-breather, thereby makes weld seam protection effect better, reduces gas waste.
The utility model is achieved by following technical solution.
A kind of circular weld reverse side air-breather, comprise air channel, described air channel inside is provided with gas block panel, in air channel outer setting, there is the vertical breather pipe being communicated with air channel, described vertical breather pipe upper end is fixed with handle, at vertical breather pipe middle part, is also provided with the horizontal communication pipe being communicated with vertical breather pipe.
In described vertical breather pipe and horizontal communication pipe, be provided with air screen.
On described gas block panel, be provided with some passages.
Described vertical breather pipe, horizontal communication pipe and handle all adopt stainless steel tube to make.
The beneficial effects of the utility model are:
Adopt circular weld reverse side air-breather described in the utility model, by the profile of the edge of this device and parts is fitted, in inside, air screen is set, by breather pipe, protective gas is caused in groove, owing to having one in air channel with the baffle plate of passage, make gas be full of air channel, thereby make sealing run protection respond well; The utility model manufacture is simple, easy to operate, greatly reduces gas waste, and weld seam protection is effective, and workman's labour intensity is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is part circular weld structural representation.
In figure: 1-handle, the horizontal wireway of 2-, the vertical wireway of 3-, 4-air screen, 5-air channel, 6-gas block panel, 7-circular weld, 8-flange.
The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of circular weld reverse side air-breather described in the utility model, comprise air channel 5, described air channel 5 inside are provided with gas block panel 6, in air channel 5 outer setting, there is the vertical breather pipe 3 being communicated with air channel 5, described vertical breather pipe 3 upper ends are fixed with handle 1, at vertical breather pipe 3 middle parts, are also provided with the horizontal communication pipe 2 being communicated with vertical breather pipe 3.Adopt the technical program, the edge of air channel 5 and the laminating of the profile of parts, cause protective gas in air channel 5 by vertical breather pipe 3 and horizontal communication pipe 2, thereby reach the effect of protection sealing run.
In described vertical breather pipe 3 and horizontal communication pipe 2, be provided with air screen 4.By air screen 4, the protective gas entering in air channel 5 can be filtered, thereby guarantee weldquality.
On described gas block panel 6, be provided with some passages.Like this, make gas be full of air channel 5, make the protection of sealing run respond well.
Described vertical breather pipe 3, horizontal communication pipe 2 and handle 1 all adopt stainless steel tube to make.
Described vertical breather pipe 3 adopts and is weldingly connected with air channel 5, horizontal communication pipe 2 and handle 1 respectively.Manufacture simple, easy to operate.
As shown in Figure 1 and Figure 2; when carrying out annular element and flange weldering 8 and connect; first the sebific duct on the sebific duct in argon tanks or ar gas passage is connected with horizontal communication pipe 2; open air valve; make argon flow amount ventilation after 2 minutes; start to weld; when welding; by the air channel of air-breather 5 profiles and the laminating of part profile; along with welding gun moves, guarantee that circular weld 7 molten baths are in the middle front part of reverse side air-breather described in the utility model, had both protected the weld seam forming; protected simultaneously and formed the weld seam not solidifying completely, the butt welded seam back side is protected.
