Abstract
The utility model belongs to fusing gas protecting welding torch accessories of welding equipment, especially involving a fusing gas protecting welding torch composite nozzle. The characteristics are: it is consisted of a main body of nozzle, and a hood, the head of the hood is connected to the cavity of one end of the main body of nozzle; the hood is composited of outer metal bushing and inner ceramic tube, or outer metal bushing and inner graphite tube; the tail of the hood is designed to inosculate with welding torch nozzles of different specifications and types. The composite nozzle of the utility model has excellent capabilities of anti-adherence, high-temperature-bearing, and anti-impacting, farthest avoiding the infection to welding quality because of adherence; the effect will be more obvious in the use of automatic welding. The composite nozzle can meet various needs of general users on different welding operations.
Description
Technical field
The utility model belongs to the gas metal-arc welding welding gun accessory of welding equipment, particularly a kind of gas metal-arc welding welding gun combining nozzle.
Background technology
Industry is known, and at the nozzle that the afterbody of the gas metal-arc welding welding gun of welding equipment is connected with the welding gun gun barrel through the insulation joint, purpose sprays protective gas, protects the weld zone.Be monolithic devices and have nozzle at present both at home and abroad now; but exist following deficiency in actual use: 1) because there is the metal problem of splashing in gas metal-arc welding; the nozzle head inwall inevitably adheres to splash; protective gas becomes turbulent flow by laminar flow when serious, directly influences welding quality.2) because the high temperature in molten bath makes the nozzle tip consume, cause welding quality to descend, have the replacing nozzle only, can satisfy welding condition.3) the insulating joint material is bakelite (thermoset plastic), can extrapolate its carburizing temperature from its injection temperature.Because the resistance self-heating of arc radiation heat, welding gun workpiece is easy to cause the insulating joint carbonization in the weld job, makes welding quality have destabilizing factor.
The utility model content
The purpose of this utility model is intended to overcome the deficiency in the prior art, and a kind of gas metal-arc welding welding gun combining nozzle is provided.
For realizing that the technical scheme that the purpose of this utility model adopted is: a kind of gas metal-arc welding welding gun combining nozzle is characterized in that: it is made up of nozzle body and headgear, and the headgear head is installed in the nozzle body one end chamber; And headgear is to be composited by pipe in metal jacket pipe and ceramic inner pipe or metal jacket pipe and the graphite; The headgear afterbody is according to the design that matches of each specifications and models torch neck.
The attaching mode of above-mentioned nozzle body and headgear be the tapering attaching or be threaded, collar chucking mode is connected.
Above-mentioned nozzle body also can be composited by metal jacket pipe and ceramic inner pipe.
The built-in screw thread of the ceramic inner pipe of above-mentioned nozzle body.
The beneficial effects of the utility model are: 1) its combining nozzle has anti-stick deposited, the high temperature resistant and anti-premium properties that beats, and has avoided to greatest extent especially using in the automation welding because of the sticking deposited influence that welding quality is caused, and effect is more obvious.2) combining nozzle can satisfy the various needs of general user, different station weld job, combining nozzle nose shapes such as flat mouthful of transposing that can be easy, closing in, awl mouth.3) prove according to field experiment that by the equivalent weld job, the life-span of the utility model one cover combining nozzle can replace about 10 of conventional spout and some insulating joints.4) combining nozzle main body of the present utility model adopts metal and pottery compacting composite construction, and ceramic built-in screw thread need not insulating joint and is connected with welding gun, has also reduced operating cost.Pottery is in all many-sides such as anti-stick deposited, high temperature resistant, insulation, impact strengths, with former nozzle bakelite not a grade, so increased the reliability of welding operation.5) combining nozzle outward appearance of the present utility model need not to electroplate, and function is better than conventional spout, and self had not both had direct contaminated environment in the manufacturing, did not have the through committing others again and processed the indirect pollution environmental problem; Use the auxiliary of chemical products such as the anti-stick application of nozzle when also need not welding operation.
Description of drawings
Fig. 1 the utility model is suitable for the structural representation of external insulation type welding gun;
The structural representation of insulated type welding gun in Fig. 2 the utility model is suitable for.
Specific embodiment
Below in conjunction with the drawings and specific embodiments structure of the present utility model is further described:
Embodiment 1 is that the utility model is applicable to external insulation type welding gun.Please refer to Fig. 1, a kind of gas metal-arc welding welding gun combining nozzle, it is made up of nozzle body 1 and headgear 2, and the headgear head is installed in the nozzle body one end chamber; And headgear 2 is to be composited by pipe 2-2 in metal jacket pipe 2-1 and ceramic inner pipe 2-2 or metal jacket pipe 2-1 and the graphite; The headgear afterbody is according to the design that matches of different size model torch neck, so nozzle body can dispose the headgear of various ways attaching torch neck.And the attaching mode of nozzle body and headgear is the tapering attaching or is threaded, and also can block figure chucking mode and connect.Nozzle body 1 is composited by metal jacket pipe 1-1 and ceramic inner pipe 1-2; The ceramic inner pipe 1-2 design of its nozzle body 1 has screw thread, need not insulating joint.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of scheme of the present utility model any simple modification, equivalent variations and modification that above embodiment did.
