, technical solution and effect it is clearer, clear, as follows in conjunction with drawings and embodiments further specifically to the utility model
It is bright.It should be appreciated that specific embodiment described herein is not used to limit originally practical new only to explain the utility model
Type.
It please refers to Fig.1 to Fig.3, the utility model provides a kind of perspective view of argon protective device for argon arc welding.Fig. 1
Middle arrow show the feed direction of steel pipe.
The argon protective device for argon arc welding includes a block body 10, and ontology offers connection table thereon
The air inlet 101 in face and lower surface, the lower surface of ontology offer a groove 103, which corresponds to welding gun 40 from ontology
One end extend along body length direction, above-mentioned air inlet 101 is connected to the groove 103；The connection of body upper surface air inlet position
There is an air inlet pipe 20, which is used for and external tunger tube（It is not shown in the figure）Connection, steel pipe 30 to be welded
Longitudinal opening 301 is upward and positioned at the lower section of ontology.
When work, steel pipe is placed in the workbench of automatic argon arc welder（It is not shown in the figure）On, the longitudinal opening court of steel pipe
On.Above-mentioned ontology can pass through more support rods（It is not shown in the figure）It is detachably secured to the workbench of automatic argon arc welder
On, whole steel pipe can be pushed through below ontology after automatic argon arc welder starting self-feeding（Side as shown by the arrows in Figure 1
To）；Make as far as possible when installation steel pipe top and body bottom portion close to avoid leakage argon gas, but guarantee steel pipe can freely be pushed away
It is dynamic.Above-mentioned air inlet pipe connects external tunger tube, and external argon gas is allowed to reach body bottom portion by air inlet pipe and air inlet
It is sprayed in groove and finally from the end of ontology；The position of welding gun is shown in figure, the groove of body bottom portion prolongs to welding gun direction
It stretches, so that welding region is covered by argon gas, to improve welding region.302 are illustrated as the longitudinal seam after welding in Fig. 1,
303 are illustrated as longitudinal seam to be welded, and longitudinal seam to be welded is small.It above-mentioned automatic argon arc welder and its send automatically
Material mode belongs to the prior art, does not repeat herein.It can be seen that the present invention dexterously utilizes steel pipe self-feeding, this is special
Property, guarantee that welding region has argon gas covering always to realize the argon arc welding of Straight Welded Pipe, and do not need to indulge entire steel pipe
All keep apart to the region of opening, this method is realized simply, and significantly improves welding effect.
Further, above-mentioned 10 top side of ontology offers the gas vent being connected to groove 102；The diameter of the gas vent
Preferably 3mm ~ 5mm.By the way that gas vent 102 is arranged, argon pressure is excessive and connector is caused to receive in groove when can prevent from receiving arc
Arc it is difficult or generation pit the defects of, further improve welding quality.
Fig. 1 and Fig. 2 are please referred to, it is observed that gas vent 102 is greater than air inlet 101 and welding gun at a distance from welding gun 40
40 distance passes through the setting, it is ensured that has sufficient argon gas to flow to welding region, while can prevent Ar Pressure in groove
Power is excessive.
Above-mentioned air inlet pipe can be directly welded on air inlet；Screw thread company can also will be carried out between air inlet pipe and air inlet
It connects.
Further, a throttle valve is provided in the air inlet pipe（It is not shown in the figure）, convenient for being carried out to argon flow
It adjusts, conveniently adapts to different welding operating conditions.
Referring to Fig. 1, further, the ontology is in narrow front and wide rear in vertical projection close to one end of welding gun, i.e.,
It is narrower at welding gun；The shape can make ontology not interfere as far as possible with welding gun, guarantee that welding is gone on smoothly.
Further refering to Fig. 3, the cross section of the groove 103 includes two section of first circular arc 1031 to feelings, and is located at this
The second circular arc 1032 in the middle part of body lower surface, the both ends of second circular arc 1032 are separately connected two the first circular arcs 1031；Institute
The radius of curvature for stating two the first circular arcs 1031 is equal to the exradius of steel pipe 30 to be welded, the song of second circular arc 1031
Rate radius is less than the exradius of steel pipe 30 to be welded.When for round steel pipe, the setting can make at the top of round steel pipe with it is recessed
Groove sidewall fitting, is effectively reduced argon gas amount of leakage, improves the reliability of argon gas protection.
