Welding gun is the part of carrying out welding operation in the welding process, has all brought into play great practical function in each big fields such as machinery, buildings.The basic functional principle of welding gun is: welding gun utilizes the high electric current of welding machine, the heat accumulation that high voltage produces melts welding wire welding gun terminal (namely conduction is chewed the place), and the welding wire of thawing is penetrated into the position that needs welding, after cooling, what soldered object was firm links into an integrated entity.
The welding gun basic configuration of prior art is direct rod shape, when welded still pipe, generally from outer surface the junction is directly welded, operation is very easy, simple, but some the time, for sealing or the aesthetic property that guarantees to weld, need the junction be welded from the inner surface of steel pipe, at this moment, operation easily in the extreme for the bigger steel pipe of internal diameter, and for the less steel pipe of internal diameter, just be difficult to operation, thereby increased staff's work difficulty, also limited the scope of application of welding gun.
The utility model content
The utility model proposes a kind of steel duct welding gun head, solved in the prior art problem that can't weld internal diameter less steel duct.
The technical solution of the utility model is achieved in that the steel duct welding gun head; comprise that water conservancy diversion overlaps and conduction is chewed; described conduction is chewed the thread eye that has be used to holding welding wire; described conduction is chewed the inner chamber end that is removable installed in described water conservancy diversion cover; described conduction chew and described water conservancy diversion cover between form the protection air duct; terminal crooked setting that described conduction is chewed, the shape that correspondence one end of described water conservancy diversion cover and described conduction are chewed is suitable.
As to improvement of the technical scheme, described water conservancy diversion cover is the telescopic flow guiding cover, described conduction chew by many intermediate connection tubes be threaded between described water conservancy diversion overlaps.
As to further improvement in the technical proposal, the diameter of described thread eye reduces from inside to outside gradually.
After having adopted technique scheme, the beneficial effects of the utility model are: because the end that conduction is chewed has carried out bending setting to a certain degree, correspondence one end of water conservancy diversion cover is also suitable with the shape that conduction is chewed simultaneously, like this, when the less steel pipe of internal diameter is welded, can directly the water conservancy diversion cover be stretched into steel duct, realize the welding of circling round to the steel pipe junction by rotating the water conservancy diversion cover, very simple and convenient.
Because the length of water conservancy diversion cover can arbitrarily be stretched, then no matter weld be positioned at steel pipe than still more shallow place, depths, the length by changing the water conservancy diversion cover and increase and decrease intermediate connection tube can be realized the welding to the steel pipe internal-surface optional position.
