Abstract
The utility model belongs to the technical field of material engineering, relating to the welding equipments of metal materials, in particular to a novel welding torch nozzle, which comprises a main nozzle, a protective nozzle and a flow valve. The protective nozzle part comprises an upper air inlet pipe, a pipe and a nozzle front with a function of height adjusting; the diameter D is ten to twenty-five millimeters. The pipes of the main nozzle and the protective are a whole body, and the angle between the two is zero to thirty degrees; using the end of the main nozzle as the base level, the pipes have intersection points respectively with the axis of the two nozzles; the distance between the two intersection points L is fifteen to forty-five millimeters. The flow valve and the upper air inlet pipe are connected to control the air flow the protective nozzle. The front nozzle can adjust the height to meet requirements of various welding positions through a thread button. During welding, the main nozzle conducts welding and protects the molten pool; the protective nozzle protects the welding seam and prevents high-temperature metal from reacting with surrounding air. The utility model has a simple structure and a convenient operation; the utility model is cute and flexible, easy to implement; the utility model saves the protective gas and the welding parts and positions are wide.
Description
Technical field
The invention belongs to field of material engineering technology, relate to the welding equipment of metal material, particularly a kind of novel torch neck.
Background technology
When utilizing the arc welding weld metal, especially during the welding of non-ferrous metal such as aluminium, magnesium, titanium alloy, because the metal of high temperature is easy to absorb O in the air
2, CO
2, N
2And H
2And form pollution, so seeming, the protection of reinforcement of weld is even more important.At present at the protection problem, mainly solve thinking and be: one, strengthen the diameter of torch neck, increase the protection area; Two, at the cover that drags of the additional argon shield in the back of welding gun.First kind of thinking so protection is regional less, protects effect relatively poor owing to be subjected to the diameter of welding gun own can not too big restriction.Though second kind of thinking protection effect is very good, owing to drag the bulky of cover, cause weldment and welding position are limited to some extent, operate not nimblely, the gas waste is seriously.
Summary of the invention
In order to overcome the deficiency that existing torch neck exists, the utility model provides a kind of novel torch neck, and this novel torch neck is simple in structure, easy to operate, can reach the excellent protection effect again, has improved the efficient and the welding quality of welding.
The technical scheme that its technical problem that solves the utility model adopts is: it is by main burner, and protection nozzle and flow valve three parts are formed.The protection nozzle segment by last air inlet pipe, pipeline and have the height regulatory function spray nozzle front end form, its diameter D is 10～25mm.Wherein the pipeline of main burner and protection nozzle is an one, and the angle between two is 0～30 °, is datum level with the main burner end, with the axis of two nozzles intersection point is arranged respectively, and distance L is 15～45mm between two intersection points.Flow valve links to each other with last air inlet pipe and controls the gas flow of protection nozzle.The front end nozzle can be adjusted the requirement that highly reaches the welding all places by screw thread.Main burner welding during welding, and to the molten bath protection, protection nozzle guard weld seam prevents that high-temperature metal and surrounding air from reacting.
The utility model has following advantage compared with similar products:
1. the twin-jet nozzle of welding gun can effectively protect the weld metal zone to be subjected to the pollution of surrounding air, thereby has guaranteed welding quality.
2. simple in structure, small and exquisite nimble, easy to operate, be convenient to implement, save protective gas, welding assembly and welding position are extensive.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a welding gun twin-jet nozzle structural representation
1. main burners among the figure, 2. protection nozzle pipe, 3. air inlet pipe on the protection nozzle, 4. protection spray nozzle front end, 5. flow control valve.6. protection nozzle, 7. passage.
The specific embodiment
In Fig. 1; the pipeline 2 as a whole structures of main burner 1 and protection nozzle; protection nozzle 6 is made up of air inlet pipe 3, protection nozzle pipe 2 on the protection nozzle and the protection spray nozzle front end 4 that has a regulatory function, flow control valve 5 with protect nozzle on air inlet pipe 3 link to each other.
Included angle A is 15 ° between main burner 1 and the protection nozzle pipe 2, and the diameter D of protection nozzle 6 is 15mm, is datum level with main burner 1 end, with the axis of two nozzles intersection point is arranged respectively, and distance L is 30mm between two intersection points.Air inlet pipe 3 is provided with passage 7 on the protection nozzle on tube wall, and the end of air inlet pipe 3 in pipeline is what seal on the protection nozzle.Flow control valve 5 links to each other with air inlet pipe 3 on the protection nozzle and controls the gas flow of protection nozzle.The front end nozzle can be adjusted the requirement that highly reaches the welding all places by screw thread.Main burner 1 welding during welding, and to the molten bath protection, protection nozzle 6 protection weld seams prevent that high-temperature metal and surrounding air from reacting.
Claims (3)
