Technical field
The present invention relates to protective device, be meant a kind of semi-automatic weld seam protective device that is used for the steel pipe welding especially.
Background technology
Commonly used often at welding titanium, pick alloy pipeline at present to argon arc welding; In the welding gun running; Weld seam and heated portion temperature after welding is higher on every side, in the cooling procedure easily by oxygen institute oxidation in the air, the welding position and around the color blackening; Even crack, cause solder yield lower.
Summary of the invention
Technical problem to be solved by this invention is: a kind of semi-automatic weld seam protective device is provided, and this protective device can improve the quality of weld seam, improves solder yield.
For solving the problems of the technologies described above; Technical scheme of the present invention is: semi-automatic weld seam protective device; Comprise the protective cover, first positioning disk that is used for the cutting ferrule steel pipe and second positioning disk that are used for the applying of steel pipe periphery wall, the applying side opening of said protective cover is provided with the protection chamber in the said protective cover; Said protective cover is provided with and the intake interface of protecting the chamber to be communicated with; Said first positioning disk and second positioning disk are provided with is convenient to the guiding annular groove of protective cover around the steel pipe rotation, and said protective cover is arranged in the guiding annular groove of first positioning disk and second positioning disk, and said protective cover is provided with the installation sleeve that is used to lay welding gun.
As a kind of preferred scheme, said protection is equipped with turbulent device in the chamber.
As a kind of preferred scheme, said turbulent device comprises the wire wire netting outer with being coated on wire that is filled in the protection chamber.
As a kind of preferred scheme, said first positioning disk and second positioning disk form by two mutual snappings of semi-round ring shape disk body.
As a kind of preferred scheme, the mounting means of said installation sleeve and protective cover is for being fixedly connected.
As a kind of preferred scheme, the mounting means of said installation sleeve and protective cover is hinged, and said installation sleeve is installed on the protective cover through jointed shaft, and said installation sleeve can rotate around jointed shaft.
After having adopted technique scheme; Effect of the present invention is: because semi-automatic weld seam protective device; Comprise the protective cover, first positioning disk that is used for the cutting ferrule steel pipe and second positioning disk that are used for the applying of steel pipe periphery wall, the applying side opening of said protective cover is provided with the protection chamber in the said protective cover; Said protective cover is provided with and the intake interface of protecting the chamber to be communicated with; Said first positioning disk and second positioning disk are provided with is convenient to the guiding annular groove of protective cover around the steel pipe rotation, and said protective cover is arranged in the guiding annular groove of first positioning disk and second positioning disk, and said protective cover is provided with the installation sleeve that is used to lay welding gun.During welding; At first be fastened on the steel pipe that needs welding, then welding gun be placed in the installation sleeve, in the protection chamber, feed inertia protection gas from intake interface with first positioning disk and second positioning disk; Welding gun welds along welding bead; Then protective cover rotates around steel pipe along the guiding annular groove with welding gun, and higher weld seam and the heat affected area thereof of temperature that welded at inertia protection gas Butt welding gun rear protected, and avoids it oxidized; Thereby avoid in weld seam and the heat affected area cooling procedure thereof because of the blackening of oxidation color and crack, improve the qualification rate of welding.
Again owing in the said protection chamber turbulent device is installed; Therefore; The turbulent flow device can become turbulent flow from the inert protective gas that the high speed that intake interface feeds is concentrated and cushion, thereby improves the protection effect of cooling off behind the protective gas butt welded seam, reduces the consumption of inert protective gas.
Because the mounting means of said installation sleeve and protective cover is hinged, and said installation sleeve is installed on the protective cover through jointed shaft, and said installation sleeve can rotate around jointed shaft, therefore, welding gun is installed in the angle that can adjust welding gun in the installation sleeve as required again.
