Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the utility model relates to a steel pipe production line is protective gas conveyor for on-line welding arranges between steel pipe transfer chain 1, including first locating piece 2 and second locating piece 3, first locating piece and second locating piece set up relatively to there is arc recess face on the opposite face respectively, formation space 9, so that steel pipe 100 passes through, first locating piece forms symmetrical protective gas conveying unit with the upper portion of second locating piece, protective gas conveying unit includes gas outlet and income gas port, connects gas outlet and the L shape protective gas passageway 7 who goes into the gas port form inside the upper portion of first locating piece and second locating piece, it supplies the system to go into the gas port connection protective gas.
Wherein, nozzle 5 and intake pipe 4 are installed respectively to gas outlet and income gas mouth. The nozzle 5 and the air inlet pipe 4 are in threaded sealing connection with the air outlet and the air inlet.
Wherein, the bottoms of the first positioning block and the second positioning block are fixed on the connecting plate 8.
During welding, the welding gun 6 sprays protective gas from two nozzles above the two first positioning blocks and the second positioning blocks to form a protective area, as shown in fig. 1, so that a straight welding seam on a steel pipe 100 conveyed from the steel pipe conveying line 1 is movably welded in a protective atmosphere, and the straight welding seam is conveyed out from the steel pipe conveying line behind. Wherein, the welding rifle is motionless, in the removal transportation process of transfer chain, realizes welding under the protective atmosphere.
It should be noted that, in the utility model, the protective gas supply system, adopt the prior art structure, as shown in fig. 4, the protective gas supply system of prior art is including the gas cylinder 10 that is equipped with high-pressure carbon dioxide, with the gaseous desicator 11 that is arranged in getting rid of the moisture content in the carbon dioxide that is connected, heat the pre-heater 13 that needs the temperature to the carbon dioxide that gets rid of moisture content, gas flowmeter 13, to the second desicator 14 that preheats the gaseous redrying of back and further get rid of moisture content to and whether the solenoid valve 15 that on-off control gas output used, the end of giving vent to anger of solenoid valve pass through the tube coupling with the intake pipe can, this is the gaseous air supply system of carbon dioxide protective gas in the technique among the existing protection welding, no longer explains.
Compared with the prior art, the beneficial effects of the utility model are that:
The utility model discloses a steel pipe production line is protective gas conveyor for on-line welding forms symmetrical protective gas conveying unit through the upper portion of first locating piece and second locating piece, protective gas conveying unit includes the gas outlet and goes into the gas port, connects the gas outlet forms with the L shape protective gas passageway of going into the gas port inside the upper portion of first locating piece and second locating piece, go into the gas port and connect the protective gas and supply the system, can realize for the corresponding protective gas of current welding machine configuration to the realization provides corresponding protection for the welding, thereby promotes the welding quality of welded steel pipe.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
