Abstract
The utility model discloses an argon arc welding device, which is used for welding a tube body conducting rectilinear motion on the tube-making assembly line and with the diameter of 32 mm to 129 mm. The argon arc welding device comprises a machine frame and an inner protective tube arranged in the tube body, wherein holes for argon circulation are formed on the inner protective tube; and a first argon arc welding gun and a second argon arc welding gun are further arranged on the machine frame at a certain interval. By virtue of the above technical scheme, the welding device has the advantages of simple structure, convenient operation and high welding quality, and can satisfy the requirement of double-side forming welding technology.
Description
Technical field
The utility model relates to welding field, particularly a kind of welder that is used for argon arc welding technique.
Background technology
In the production process of automotive silencing pipe, must guarantee that the welding position on the hush tube defectives such as crackle or fracture can not occur under the external force effect of carrying out bending, producing during complicated technology such as rise pipe, draw, for satisfying above-mentioned requirements, except weld seam itself does not have the weld defect, the height of weld seam must be 1.05～1.2 times of welding base metal, and welding is required to be double-faced forming.
Existing welder generally only adopts a welding gun, adopts single face welding and double face shaping method, like this in single rifle welding process, and when having guaranteed that outside weld reaches specification requirement, then not moulding of inside weld; When guaranteeing that inside weld reaches specification requirement, then outside weld is on the low side, and final welding effect is bad, causes weld seam higher or on the low side.If weld seam is higher, then the transition position of weld seam and welding generation stress is concentrated, and follow-up manufacture craft is prone to depression; If weld seam is on the low side, then the intensity of weld seam own is low, becomes stress concentration point, and the manufacture craft in the back just is easy to generate fracture.Simultaneously, because the production of tubulation line is rectilinear motion, single welding gun also has no idea to satisfy once more the demand that weld seam welds that repeats.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to operate, and can satisfy the welder of the welding procedure needs of double-faced forming, welding quality height.
The technical solution of the utility model is: a kind of argon arc welding welder, being used for moving linearly, pipe diameter on the tubulation streamline is that the body of ￠ 32mm～￠ 129mm welds, include frame and be arranged at the interior interior keeping of body, interior keeping is provided with the hole that is used for the argon gas circulation, also be provided with first argon-arc welding gun and second argon-arc welding gun on the described frame, be separated with certain distance between first argon-arc welding gun and second argon-arc welding gun.
As a kind of improvement of technique scheme, described frame also is provided with first manipulator that is used to grip first argon-arc welding gun.
As further improvement in the technical proposal, described frame also is provided with second manipulator that is used to grip second argon-arc welding gun.
After adopting technique scheme, have following beneficial effect: frame is provided with first argon-arc welding gun, guaranteed that inside weld reaches specification requirement, body is through second argon-arc welding gun afterwards, the second argon arc rifle solves the outside weld height problem, make the outside weld height reach specification requirement, finally finish the specification requirement of qualified double-faced forming, the welding quality height.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of a kind of argon arc welding welder of the utility model.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
Please refer to of the present utility model a kind of embodiment shown in Figure 1, a kind of argon arc welding welder, be used for the body 2 of moving linearly on the tubulation streamline is welded, the diameter of body 2 is ￠ 32mm～￠ 129mm, include frame 1 and the interior keeping 16 that is arranged in the body 2, interior keeping 16 is provided with the hole 160 that is used for the argon gas circulation, also is provided with first argon-arc welding gun 10 and second argon-arc welding gun, 12, the first argon- arc welding guns 10 and 12 of second argon-arc welding guns on the described frame 1 and is separated with certain distance.
Frame 1 is provided with first argon-arc welding gun 10; factors such as kind according to welding tubing; preestablish the welding current of first argon-arc welding gun 10 and second argon-arc welding gun 12; be connected with the protection argon gas in the interior keeping 16; form the argon shield zone by the hole in the interior keeping 16 160; the main effect of first argon-arc welding gun 10 is to guarantee that the inside weld on the body 2 reaches specification requirement; then the body rectilinear motion pass by an end distance from; during through second argon-arc welding gun 12; second argon-arc welding gun 12 begins welding; the main effect of second argon-arc welding gun 12 mainly solves the outside weld height problem; making the outside weld height is 1.05～1.2 times of welding base metal; finally finish the specification requirement of qualified double-faced forming, the weldquality height.This welder is simple in structure, easy to operate, is fit to be applied to suitability for industrialized production.
In the present embodiment, frame 1 also is provided with first manipulator 101 that is used to grip first argon-arc welding gun 10, manipulator is set after, manipulator can freedom be controlled first argon-arc welding gun 10 independently and is moved flexibly, guarantees the precision of welding, the automaticity height.
In the present embodiment, also be provided with second manipulator 102 that is used to grip second argon-arc welding gun 12 on the frame 1, manipulator is set after, manipulator equally can freedom be controlled second argon-arc welding gun 12 independently and is moved neatly, guarantees the precision of welding.
Compared with prior art, frame is provided with two argon-arc welding guns, first argon-arc welding gun has guaranteed that inside weld reaches specification requirement, body is through second argon-arc welding gun afterwards, the second argon arc rifle solves the outside weld height problem, make the outside weld height reach specification requirement, so both made inside weld reach the requirement of moulding, the height of outside weld has also reached requirement, finally finished the specification requirement of double-faced forming, the weldquality height that welding forms, this apparatus structure is simple simultaneously, easy to operate, be fit to very much be applied in the modern industrialization production.
Above-described only is principle of the present utility model and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, can also make some other modification, also should be considered as protection domain of the present utility model.
