Background
During welding of a welding gun, particularly argon tungsten-arc welding, shielding gas is usually introduced into the welding gun to protect an electric arc at the bottom of the welding gun, and argon tungsten-arc welding is used as shielding gas to protect a weld pool. As the welding gun moves, the welding line is not completely cooled, and the protective gas needs to be continuously sprayed out by using a drag cover to protect the welding line. The welding area is large in common straight seam or circular seam welding, the outline dimension of the used drag cover is also large, and the right-angle welding seam welding working condition cannot be effectively protected. The conventional right-angle towing cover cannot meet the requirements of multidirectional protection and swing, and the weld joint protection effect needs to be optimized.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a right-angle welding seam towing cover.
The technical scheme of the utility model is as follows:
the utility model provides a right angle welding seam drags cover, includes roof, bottom plate and curb plate, drags cover side projection and is isosceles trapezoid, is equipped with the through-hole in the middle of roof, the bottom plate, and welder runs through the through-hole, all is equipped with the aperture of ventilating on bottom plate and the curb plate, is equipped with gas inlet on the roof, exists the space between roof through-hole department and the welder, and the roof through-hole is equipped with the seal cover between welder and the roof, makes welder and roof department seal, and the protection gas is passed in from the roof back and is followed bottom plate and curb plate blowout. A certain gap exists between the through hole of the top plate and the welding gun, so that the welding gun can swing and weld at the right-angle welding seam on the premise of increasing the protective gas of the towing cover, and the swing and welding of the welding gun are not affected by the increase of the towing cover.
Preferably, the top plate and the bottom plate are transparent plates. And the welding pool and the protection gas inlet condition are convenient to observe.
Preferably, the density of the ventilation holes on the bottom plate is greater than that of the ventilation holes on the side plates. The majority of the shielding gas is concentrated at the bottom for release, and the small part is released at the side, so that the shielding gas is more beneficial to gas shielding.
Preferably, the side plates are provided with sliding wheels, and the sliding wheels are contacted with the right-angle weldment. The drag cover and the welding gun can walk on the weldment through the sliding wheel when in right-angle welding, so that the welding process is more stable.
Preferably, the top plate is provided with a water cooling device, the water cooling device is a water cooling pipe, the water cooling pipe is arranged at the top plate, and the water inlet and the water outlet are arranged at one side of the top plate. The roof increases the water-cooling, is convenient for reduce the construction temperature of towing cover and seal cover, extension operating time, and does not influence the welding and go on.
Preferably, the number of the gas inlets is two, and the gas inlets are symmetrically distributed on two sides of the welding gun. So that the air intake is more uniform.
The utility model has the beneficial effects that:
most TIG welding guns have central shielding gas, after the right-angle welding seam drags the cover, when welding right-angle weldment, through superposition shielding gas, can be better protect the molten pool, make welding quality obtain very big improvement. Simultaneously this application can laminate right angle weldment more, does not influence the welding swing when advancing steadily.
