Description
Technical field:
The utility model relates to welding technology field more particularly to a kind of accessories of welder.
Background technique:
In the prior art, with the high speed development of the industries such as ship, engineering machinery, automobile manufacture, manufacturing industry is to metal welding
The dependence for connecing especially arc welding increases year by year.Carbon dioxide gas arc welding is one kind of arc welding, is mainly characterized by
More stable gas is used to replace solid electrode coating or solder flux as protective layer.The CO sprayed from nozzle2Gas can be with
Effective protective layer is formed in arc region, prevents air from entering molten bath.Consumable electrode (welding wire) is constantly sent by wire pushing roller
Into, electric arc is generated between workpiece, under the action of arc heat, is melted welding wire and workpiece and is formed molten bath, with the movement of welding gun,
Molten bath solidifies to form weld seam.
Carbon dioxide welding gun includes that components, the ignition tips such as ignition tip, connecting rod, protection mouth are mounted on protection mouth through insulation sleeve
It is interior；It is influenced to make welding region not by outside air, aperture of the carbon dioxide gas through connecting rod radially sprays carbon dioxide
Gas enters in protection mouth cavity, and carbon dioxide gas sprays laminar flow after flowing through protection mouth, this laminar flow is made to shroud welding region, protects
Shield mouth is the important channel to welding section conveying protective gas.But since existing protection mouth volume is larger, heavier-weight,
In prolonged welding process, it is easy that operator is made to feel fatigue, to influence welding effect.In addition, protecting mouth in welding
Inner wall is easy to stick welding slag, causes tip inner wall to block, and be difficult to clear up, and reduces the service life of protection mouth.
Utility model content:
The purpose of this utility model is to provide a kind of protection mouths, to solve at least one skill as described in the background art
Art problem.
Specifically, the utility model provides a kind of protection mouth, the protection mouth includes protection mouth main body, and through
The ignition tip receiving channel of mouth body interior is protected, the protection mouth main body includes protection mouth base portion, extension, the protection mouth
Base portion is connected with the extension, and the protection mouth base portion includes fixing end, the first connecting pin, and the fixing end is provided with solid
Determine portion, and be fixed on the insulation sleeve of welding gun, first connecting pin is provided with the first annular boss, the second annular boss, institute
It states the first annular boss to be arranged concentrically with the second annular boss, forms ring between first annular boss, the second annular boss
Shape groove；The extension includes extension main body, and the third annular boss being arranged in extension main body, the third ring
The one end of shape boss far from extension main body is second connection end, one end far from third annular boss in the extension main body
For free end, the third annular boss is matched with the annular recess.
The setting of first annular boss, the second annular boss, third annular boss can make to protect mouth base portion, prolong
The contact of extending portion more closely, and can prevent the leakage of protection mouth inner silica carbon gas.
Preferably, the protection mouth base portion uses copper, copper alloy or red copper material, and the extension uses aluminium alloy material
Material.
Aluminum alloy materials density is smaller, and intensity is high, sets aluminum alloy materials for extension, can guarantee to protect mouth
In the case where mechanical strength, mitigate the weight of protection mouth, increase the operability of protection mouth, improves welding efficiency.Meanwhile aluminium closes
The cost of material is low for gold, and plasticity is good, can further decrease production cost.

The detachable setting of the protection mouth can carry out needle to the part of attachment welding slag when protecting mouth attachment welding slag
To property replacement (replacement protection mouth base portion or extension), and the entire protection mouth of replacement is not had to, regardless of protection mouth base portion, still prolongs
Extending portion, preparation process is simpler than protection mouth, by adopting the above technical scheme, not only can be with save the cost, but also improves production effect
Rate.In addition, when the protection mouth base portion uses aluminum alloy materials using copper, copper alloy or red copper material, the extension, it can
It is more easy to be laborsaving when enabling user's replacement operation.
Preferably, the fixing end inner wall is provided with internal screw thread, will be described by matching with the screw thread of welding gun insulation sleeve
Protection mouth is fixed.
Preferably, the fixing end outer wall is provided with ribs, and the setting of the ribs can increase the machine of protection mouth
Tool intensity.It is furthermore preferred that extending direction setting of the ribs along protection mouth.When protection mouth and insulation sleeve are matched by screw thread
When conjunction, the setting of ribs can increase operability when protection mouth is fixed.
Preferably, the sectional area of the extension free end is less than the sectional area of the second connection end.Above-mentioned setting, can
To play gathering gas, prevent carbon dioxide gas by the diluted effect of ambient atmos.
Preferably, the second connection end is provided with outer wall limiting stand 22, inner wall limiting stand 23, the third annular boss
It is arranged between outer wall limiting stand, inner wall limiting stand.
Preferably, the outer wall limiting stand, inner wall limiting stand width respectively with the first annular boss, the second annular boss
It is equal.Such setting, when making to protect mouth base portion, extension combination, better tightness.
Preferably, welding slag preventing boss is provided on the inner wall limiting stand.When welding, welding slag is likely to enter protection mouth
In the contact of base portion, extension is stitched, make (to protect mouth base portion as replaced) after protecting mouth replacement component, two parts component contact is not tight
It is close, influence welding effect, and the setting of welding slag preventing boss, the generation of this case can be effectively prevented.
Preferably, the welding slag preventing boss is taper platform.Such setting can further decrease protection mouth inner wall attachment weldering
A possibility that slag.
