Abstract
The utility model discloses a semi-automatic welding dust exhaust pipe mounting structure belongs to welding equipment technical field, including the welder of the dust absorption pipe of portable welding fume purifier and welding machine, its characterized in that: the flexible dust exhaust pipe is arranged at the pipe opening of the dust exhaust pipe through the reducing connector, the pipe opening of the flexible dust exhaust pipe is close to the gun head of the welding gun, and the flexible dust exhaust pipe is fixed on the welding gun through the locking frame. This is novel to have realized the tracking dust exhaust, has solved the long welding seam of big work piece and has used portable welding fume purifier smoke and dust to collect the problem that the cover can not follow the tracks of removal. Through many times of experiments, the angle and the distance of the flexible dust exhaust pipe on the welding gun side are adjusted to the optimal size, and in the process of moving welding, the smoke dust collecting port of the flexible dust exhaust pipe is always kept above the molten pool, so that the dust exhaust effect is obviously improved.
Description
Technical Field
The utility model belongs to the technical field of the welding equipment, especially, relate to a semi-automatic welding dust exhaust pipe mounting structure.
Background
Welding fume refers to solid particles formed during the welding process and which can float in the air for a long time and are generated by welding. It is a main substance which pollutes the working environment and damages the health of workers, and is also a main factor of occupational disease hazards, and can cause various occupational lung diseases including pneumoconiosis. In recent years, the environmental protection treatment strength is continuously increased in China, welding fume also belongs to key treatment and inspection objects of environmental protection departments, once the environmental protection inspection of enterprises does not reach the standard, the enterprises face the results of fine payment, production halt and the like, and serious people need to research the responsibility of enterprise responsibility, so that the enterprises lose the living and developing space.
At present, in a welding workshop, the most widely applied welding fume treatment equipment is a movable welding fume purifier. The equipment is dust removing equipment for purifying smoke dust in the welding spot area of a single station, and has higher absorption and purification efficiency on welding smoke generated by a single welding spot. For the welding process of individual large workpieces, long beads, it is necessary to perform welding using semi-automatic equipment, i.e., a welding gun is moved and a welding operation is performed over a large area. The dust collecting cover can not move along with the welding gun in the welding process, and the dust discharging effect is poor. On the other hand, the smoke dust collecting cover of the movable welding smoke purifier is large, smoke dust cannot be collected in a short distance, the problem of lateral smoke leakage exists, and the smoke dust collecting rate is low.
SUMMERY OF THE UTILITY MODEL
Problem to prior art existence, the utility model provides a solve semi-automatic welding dust exhaust pipe mounting structure of the poor problem of current jumbo size weldment dust absorption effect.
The utility model discloses a realize like this, a semi-automatic welding dust exhaust pipe mounting structure, including the welder of the dust absorption pipe of portable welding fume purifier and welding machine, its characterized in that: the flexible dust exhaust pipe is arranged at the pipe opening of the dust exhaust pipe through the reducing connector, the pipe opening of the flexible dust exhaust pipe is close to the gun head position of the welding gun, and the flexible dust exhaust pipe is fixed on the welding gun through the locking frame.
The utility model provides a semi-automatic welding dust exhaust pipe mounting structure utilizes thinner flexible dust exhaust pipe to combine together welding fume purifier and semi-automatic welding equipment, has realized the trail dust exhaust, has solved the long welding seam of big work piece and has used portable welding fume purifier smoke and dust to collect the problem that the cover can not trail the removal. Through many times of experiments, the angle and the distance of the flexible dust exhaust pipe on the welding gun side are adjusted to the optimal size, and in the process of moving welding, the smoke dust collecting port of the flexible dust exhaust pipe is always kept above the molten pool, so that the dust exhaust effect is obviously improved.
In the above technical solution, preferably, the reducing connector includes a thick pipe portion connected to a nozzle of the dust collection pipe, a thin pipe portion connected to the dust discharge pipe, and a taper pipe portion connected between the thick pipe portion and the thin pipe portion.
In the above technical scheme, preferably, the locking frame includes two locking pieces, the two locking pieces are respectively provided with a pipe body concave portion and a gun body concave portion, the two locking pieces are fixed by screws, the pipe body concave portions of the two locking pieces form a locking hole for locking the flexible dust exhaust pipe, and the gun body concave portions of the two locking pieces form a locking hole for locking the head of the welding gun.
