Abstract
The utility model discloses a nozzle of a gas shielded welding gun for a small groove and a narrow gap and relates to the technical field of steel structure production and machining. The nozzle comprises a nozzle body (1), the nozzle body (1) comprises a large-head cylinder (11) and a small-head cylinder (12), the large-head cylinder (11) is connected with an elbow pipe of the welding gun (3), ends of the small-head cylinder (12) are connected with welding wires (7), and the large-head cylinder (11) and the small-head cylinder (12) are connected with each other in a smooth transition mode. By means of the nozzle of the gas shielded welding gun for the small groove and the narrow gap, the welding deposited filling content of a thick plate can be reduced under the condition that welding qualities and equal weld joint stressed structures are guaranteed, and the welding stress is reduced.
Description
Technical field
The utility model relates to steel construction production and processing technical field, specifically the nozzle of the gas protective welding gun in the narrow gap of a kind of little groove.
Background technology
At present, in the construction steel structure field, in welding during steel plate, the impact because of the factors such as elongation of torch neck diameter and welding wire, generally all adopt the mode of large groove broad gap welding to be welded, effectively to guarantee weldquality.But large groove broad gap welds that not only the deposited metal loading is very large, and the welding stress produced is also larger, easily, on the structure generation impact, therefore is necessary to be improved.
Summary of the invention
The purpose of this utility model is to provide the nozzle of the gas protective welding gun in the narrow gap of a kind of little groove, and it can reduce the deposited loading of thick plates under the condition that guarantees weldquality and weld seam force structure equity, reduces welding stress.
To achieve these goals; the technical solution of the utility model is: the nozzle of the gas protective welding gun in the narrow gap of little groove; comprise nozzle body; it is characterized in that: described nozzle body comprises the major part cylinder that is connected with the bend pipe of welding gun; and end is connected with microcephaly's cylinder of welding wire, between described major part cylinder and microcephaly's cylinder for being connected smoothly.
The external diameter of described major part cylinder is 18～25mm, and the external diameter of described microcephaly's cylinder is 14～17mm.
The external diameter of described major part cylinder is about 20mm, and the external diameter of described microcephaly's cylinder is about 15mm.
Compared with prior art, the beneficial effects of the utility model are the utility model:
1, the welding operator in use can be clearly seen that welding wire head and solder joint in molten bath, convenient operation, use.
2, can in the little groove in the narrow gap of slab, use, and assurance weldquality that can be good, root of weld repair rate reduces.
3, the weld(ing) deposit loading greatly reduces, and welder's labour intensity obviously reduces.
4, can welding material and artificial cost-saving.
The accompanying drawing explanation
Fig. 1 is the structural representation that contains welding gun of the present utility model.
Fig. 2 will be for containing welding gun of the present utility model and the structural representation of the member that need to be welded when welding.
Fig. 3 is the utility model structural representation.
1-nozzle body in figure, 11-microcephaly cylinder, 12-major part cylinder, 2-bend pipe, 3-welding gun, 4-slab, 5-pad, the button on the 6-welding gun, 7-welding wire, 8-weld seam.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.By explanation, make advantage of the present utility model become more clear and easily understand simultaneously.
Consult accompanying drawing known: as shown in Figure 1 to Figure 3; the nozzle of the gas protective welding gun in the narrow gap of little groove; comprise nozzle body 1; it is characterized in that: described nozzle body 1 comprises the major part cylinder 11 that is connected with the bend pipe 2 of welding gun 3; and end is connected with microcephaly's cylinder 12 of welding wire 7, between described major part cylinder 11 and microcephaly's cylinder 12 for being connected smoothly.
The external diameter of described major part cylinder 11 is 18～25mm, and the external diameter of described microcephaly's cylinder 12 is 14～17mm.
The external diameter of described major part cylinder 11 is about 20mm, and the external diameter of described microcephaly's cylinder 12 is about 15mm.
In practical work process, nozzle body 1 is connected with the bend pipe 2 of welding gun 3, nozzle body 1 consists of major part cylinder 12 and microcephaly's cylinder 11, and major part cylinder 12 adopts level and smooth too low the connection with microcephaly's cylinder 11 junctions, and stretch out at the top of welding wire 7 microcephaly's cylinder 11 from nozzle body 1.
Adopt said structure, when certain slab 4 with the weld seam 8 in the narrow gap of little groove need to be welded, welding wire 7 is extend into by microcephaly's cylinder 11 in the weld seam 8 in the narrow gap of little groove and carry out welding, the length that welding wire 7 stretches into nozzle body 1 does not so need to lengthen and just can be welded, thereby can be good at guaranteeing weldquality, and the operator in use can see welding wire head and solder joint in welding pool, be easy to use.
The utility model is in the use state, utilize the utility model welding slab 4 weld seams, microcephaly's cylinder 11 of nozzle body 1 stretches in narrow gap clivia mouth 8, and welding wire 7 contacts with backing plate 5, the button 6 of pressing on welding gun 3 just can carry out welding operation, and it is simple to operation.
Other unspecified part all belongs to prior art.
