Abstract
The utility model discloses a welding baffle plate for argon arc welding of a pipe fitting. The welding baffle plate comprises a bracket, wherein a baffle plate part is rotationally arranged on the bracket and is in a circular arc shape; a plurality of V-shaped grooves are formed in an intrados of the baffle plate part; the width of each V-shaped groove is gradually reduced along anarc surface; connecting rods are mounted at the two ends of the baffle plate part; support rods are arranged on a bottom plate and articulated with the connecting rods; trapezoidal grooves are formed in the connecting rods; the welding baffle plate further comprises air cylinders; the air cylinders are arranged on the bottom plate; and bulges are mounted at expansion ends of the air cylinders and arranged in the trapezoidal grooves in a sliding manner. During use, since the V-shaped grooves are formed in the intrados of the baffle plate part, welding flux residue generated by welding is bounced continuously among many oblique surfaces due to an oblique surface bounce principle, finally kinetic energy of the residue is consumed, sparks and splattering of the welding flux residue all around are effectively avoided, and the indoor operational environment quality is ensured.
Description
Technical field
The utility model relates to a kind of shutter, specifically refers to argon arc welding pipe fitting welding shutter.
Background technology
Stainless steel welded pipe requires fusion penetration through welding; oxide-free is mingled with, and heat affected area is as far as possible little, and the argon arc welding of tungsten electrode noble gas protecting has good adaptability; welding quality is high, through welding performance is good, and its product is used widely in the industry such as chemical industry, nuclear industry and food.Speed of welding is not high is the weak point of argon arc welding, and for improving speed of welding, foreign study has been developed several different methods.Wherein by the development of single electrode list welding torch, adopt the welding method of the many welding torches of multi-electrode to apply aborning.The general argon arc welding that adopts three electrode welding torches, welded still pipe wall thickness S >=2mm, speed of welding improves 3-4 doubly than single welding torch, and welding quality is also improved.Argon arc welding and plasma weldering combination can be welded the steel pipe of larger wall thickness, in addition, and the hydrogen of 5-10% in argon gas, then adopt the high-frequency impulse source of welding current, also can improve speed of welding.First the joint of preparing welding is handled well, adopt the filling metal of doing with the welding wire of 904L material of the same race, one side welding one side is watered weld seam with cold water, welding temperature is controlled at below 80 ℃, speed of welding is more than 45～50 cm per minute, weld seam breadth depth ratio remains on 1.5: 1～between 2: 1, and weldment thickness≤12mm.Then at face of weld, carry out acid wash passivation processing.Its advantage is to weld at low temperatures, the conversion between molecule does not occur in 904L stainless steel inside, has avoided the phenomenon of fragility conversion, and the bulk deformation of weldment has been controlled in the generation of the defects such as intercrystalline corrosion while also having avoided welding, fire check.
During steel-pipe welding; for guaranteeing good welding effect, generally first will treat that Coiling Welded Pipe is placed in plug, then by soldering tip, steel pipe seam be welded; when soldering tip contacts with weld seam; conventionally can produce more Mars and residual scolder, Mars splashes everywhere when avoiding welding, and general employing comparatively simply blocked way; with cover plate by the partial occlusion of steel pipe seam; but DeGrain, and solder residue can be scattered everywhere, affects the quality of operating environment.

The purpose of this utility model is achieved through the following technical solutions:
Argon arc welding pipe fitting welding shutter, comprise support, support is fixed on base plate, on described support, rotate and be provided with shutter, described shutter is circular arc, on shutter intrados, be provided with a plurality of V-shaped grooves, and the groove width of V-shaped groove reduces gradually along cambered surface, the two ends of shutter are all provided with connecting rod, are provided with support bar on base plate, support bar and rod hinge connection, on described connecting rod, have dovetail groove, also comprise that cylinder, cylinder are arranged on base plate, on the telescopic end of described cylinder, projection is installed, projection is slidably arranged in dovetail groove.In the time of in steel pipe is inserted in the plug fixing, start cylinder, on the output of cylinder, push up, one end of drivening rod moves up, now shutter starts to move down under connecting rod stressed, until shutter covers a side of steel pipe, is to strengthen result of use, can simultaneously in the both sides of plug, install and use the utility model, only the position of remaining weld seam is left soldering tip for and is carried out welding job; In use procedure, the V-shaped groove arranging on shutter intrados, can utilize inclined-plane bounce-back principle, solder residue constantly bounce-back in numerous inclined-planes that welding is produced, the kinetic energy self having is the most at last exhausted, effectively prevented that Mars and solder residue from splashing everywhere, kept indoor operating environment quality.
Also comprise feeder, described feeder is fixed on base plate.Through the continuous bounce-back of shutter intrados, solder residue directly falls in the feeder under plug, finally by staff, is focused on.
Two ends, left and right at described shutter are provided with side shield, and described side shield is circular arc.For preventing that solder residue from being ejected by shutter two ends, the circular arc side shield of setting can stop it, and the solder residue producing while guaranteeing welding falls into feeder completely, improves the efficiency of collecting.
Upper end at described shutter is also provided with U-shaped handle.When cylinder startup goes wrong, the movement of shutter can manually realize by U-shaped handle.
Described feeder is inclined on base plate.The feeder tilting can automatically skid off when solder residue runs up to a certain degree, when reminding staff to collect, has also effectively prevented that scolder from filling up feeder and affect moving freely after steel-pipe welding.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model argon arc welding pipe fitting welding shutter, in use procedure, the V-shaped groove arranging on shutter intrados, can utilize inclined-plane bounce-back principle, solder residue constantly bounce-back in numerous inclined-planes that welding is produced, the kinetic energy self having is the most at last exhausted, and has effectively prevented that Mars and solder residue from splashing everywhere, has kept indoor operating environment quality;
2, the utility model argon arc welding pipe fitting welding shutter, for preventing that solder residue from being ejected by shutter two ends, the circular arc side shield of setting can stop it, and the solder residue producing while guaranteeing welding falls into feeder completely, improves the efficiency of collecting.
3, the utility model argon arc welding pipe fitting welding shutter, through the continuous bounce-back of shutter intrados, solder residue directly falls in the feeder under plug, finally by staff, is focused on.
