Abstract
The invention discloses a kind of argon arc welding gun, comprise welding gun matrix (1) and connected argon nozzle (2), described argon nozzle (2) is positioned at welding gun matrix (1) below, also comprises an electrode (3), be fixedly connected on welding gun matrix (1) inner, and stretch out argon nozzle (2) outward; Also comprise a transparent argon protective cover (3), be connected on welding gun matrix (2); Described electrode (3) also stretches out argon protecting cover (4) outward.Of the present invention simple and reasonable, can effectively by air exclusion outside welding zone, thus improve the quality of welding, there is stronger practicality.
Description
Technical field
The invention belongs to welder field, particularly relate to a kind of argon arc welding gun.
Background technology
Argon arc welding is also called argon shield weldering.Be exactly around arc welding, lead to argon fox protective gas, by air insulated outside welding zone, prevent the oxidation of welding zone; Due to argon arc welding arc stability, beautiful appearance during welding, non-welding surface slag, is out of shape the densification of little weld seam, is widely used in practice is produced.But find in practice, around the welding zone that traditional argon-arc welding gun welded, often there will be the phenomenon of burning and crackle.Its reason is that the argon gas that welding gun ejects effectively by air exclusion outside, thus can not cause the oxidation of welding zone, has had a strong impact on the quality of welding.In order to improve welding quality, often can adopt raising argon flow amount, playing the object of air insulated outside welding zone.But this mode causes the waste of argon gas, simultaneously when argon flow amount is excessive, argon shield air-flow may be made to form turbulent flow, air is involved in protection zone, reduces protected effect on the contrary.
Summary of the invention
Object of the present invention is the shortcoming overcoming prior art, under providing a kind of prerequisite not wasting argon gas, effectively air effectively can be isolated in the welding gun outside welding zone.
For solving the problems of the technologies described above, technical scheme of the present invention is specific as follows:
A kind of argon arc welding gun, comprise welding gun matrix and connected argon nozzle, described argon nozzle is positioned at the below of welding gun matrix, also comprises an electrode, is fixedly connected on welding gun intrinsic silicon, and stretches out outside argon nozzle;
It is characterized in that: also comprise a transparent argon protective cover, be connected on welding gun matrix;
Described electrode stretches out outside argon protecting cover.
Further, adopt screw to be connected between described argon protecting cover with weldering welding gun matrix, the overall structure of described argon protecting cover is cylinder-shaped, and described cylindrical shell is arc-shaped convex in the side near its exit.
Further, adopt screw to be connected between described argon protecting cover with welding gun matrix, the structure of described argon protecting cover is cone, and less one open-ended of diameter, one end face closure that diameter is larger is also connected with described welding gun matrix phase.
Further, be connected bottom described argon protecting cover with described welding gun matrix, described screw is circumferentially evenly arranged in argon protecting cover cylinder body bottom plane.
Of the present invention simple and reasonable, can effectively by air exclusion outside welding zone, thus improve the quality of welding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of the present invention.
Fig. 2 is the structural representation of the second embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the present invention includes welding gun matrix 1, with connected argon nozzle 2, one electrode 3 is fixedly connected on the inside of welding gun matrix 1 and stretches out outside nozzle 2, also comprise a transparent argon protective cover 4, described argon protecting cover 4 is overall cylindrical, but is arc-shaped convex 4a in the cylinder sides near its outlet; To guarantee that electrode 3 head will be exposed at outside described cylinder protective cover 4 simultaneously; When argon gas sprays from nozzle 2; the argon protecting cover 4 being arranged on nozzle 2 outside can prevent argon gas from spreading to surrounding effectively; only be confined to the neighboring area in protective cover 4 exit; the convex 4a of circular arc in cylinder exit rises and the argon gas of ejection can be made to obtain good air-flow, thus better by air insulated outside welding zone.
As the second embodiment of the present invention; as shown in Figure 2; described argon protecting cover 4 is cone; the larger one end of diameter is closed and is connected with welding gun matrix phase, the open at one end that diameter is less, and the argon gas sprayed from nozzle is due to the effect of the cone protective cover 4 of outside; effectively gas can be converged to cone outlet place; form powerful argon stream in exit, thus by air exclusion outside welding gun, improve welding quality.
These are only the present invention's preferably two embodiments, do not limit to and the present invention.
Claims (1)
1. an argon arc welding gun, comprise welding gun matrix (1) and connected argon nozzle (2), described argon nozzle (2) is positioned at welding gun matrix (1) below, also comprises an electrode (3), be fixedly connected on welding gun matrix (1) inner, and stretch out argon nozzle (2) outward; It is characterized in that: also comprise a transparent argon protective cover (4), be connected on welding gun matrix (1); Described electrode (3) also stretches out argon protecting cover (4) outward; Adopt screw to be connected between described argon protecting cover (4) with weldering welding gun matrix (1), the overall structure of described argon protecting cover (4) is cylinder-shaped, and described cylindrical shell is arc-shaped convex (4a) at the medial surface near its exit.
