Abstract
The utility model relates to the logical protective gas fixture of a kind of welding, comprise ventilation shower nozzle (1) and vent line (2), described ventilation shower nozzle (1) is cylindrical cavity structure, vent line (2) is rice font welded pipe line structure, and vent line (2) is fixedly connected in ventilation shower nozzle (1); There are some breeder tubes in the upper surface of ventilation shower nozzle (1), in the middle of the rice font pipeline of vent line (2), have a breather pipe to be connected, in rice font pipeline, have some apertures down.Compared with prior art, adopting the utility model uniformly gas can be ejected into face of weld when welding, improving welding quality.
Description
Technical field
The utility model relates to a kind of soldering appliance, particularly the logical protective gas fixture of a kind of welding.
Background technology
Gas shielded arc welding is good owing to having welding quality, and efficiency is high, easily realizes the advantages such as automation and is developed rapidly.Adopt the object of protection-gas welding to be to improve weldquality, reduce weld seam heat effect bandwidth, avoid material to be oxidized, but Problems existing is that gas can be directly injected to weldment surface at present, affects welding quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of logical protective gas fixture of welding that gas uniform can be ejected into weldment surface, thus improves welding quality.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
The logical protective gas fixture of a kind of welding, its formation comprises ventilation shower nozzle and vent line, and described ventilation shower nozzle is cylindrical cavity structure, and vent line is rice font welded pipe line structure, and vent line is fixedly connected on ventilation shower nozzle; There are some breeder tubes in the upper surface of ventilation shower nozzle, are connected at the rice font pipeline middle air pipe of vent line, in rice font pipeline, have some apertures down.
The logical protective gas fixture of above-mentioned welding, have pipe fitting pilot hole in the lower surface of ventilation shower nozzle, breather line is inserted in pipe fitting pilot hole.
The beneficial effects of the utility model: compared with prior art, adopt the utility model uniformly gas can be ejected into face of weld when welding, and improve welding quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is breather line sectional view of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Detailed description of the invention
Embodiment 1.As shown in Figure 1, comprise ventilation shower nozzle 1 and vent line 2, ventilation shower nozzle 1 is cylindrical cavity structure, and vent line 2 is rice font welded pipe line structure, and main material is stainless steel tube, diameter 10 millimeters; Have some breeder tubes (diameter 1 millimeter) in the upper surface of ventilation shower nozzle 1, in the middle of the rice font pipeline of vent line 2, have a breather pipe to be connected, diameter 12 millimeters, has some apertures down, as shown in Figure 2 in rice font pipeline.Have a pipe fitting pilot hole (diameter 12 millimeters) in the lower surface of ventilation shower nozzle 1, this pilot hole is mainly used for breather line 2 to insert use, and breather line 2 is inserted in pipe fitting pilot hole, is fixedly connected on by vent line 2 on ventilation shower nozzle 1.
Operation principle: welding protection gas enters through the breather pipe in the middle of breather line 2; downward jet by being formed after rice font pipeline; then uniform upwards jet loop is formed via after the lower surface baffle plate bounce-back of ventilation shower nozzle 1; guarantee that gas is by being ejected into face of weld by gas uniformly after this device, improve welding quality.
Claims (2)
1. the logical protective gas fixture of welding, comprise ventilation shower nozzle (1) and vent line (2), it is characterized in that: described ventilation shower nozzle (1) is cylindrical cavity structure, vent line (2) is rice font welded pipe line structure, and vent line (2) is fixedly connected in ventilation shower nozzle (1); There are some breeder tubes in the upper surface of ventilation shower nozzle (1), in the middle of the rice font pipeline of vent line (2), have breather pipe to be connected, in rice font pipeline, have some apertures down.
