Summary of the invention
The purpose of this utility model provide a kind of in the environment of narrow welding space, high temperature preheating the rifle body assembly of continuous sequence.
The utility model adopts following technical scheme to realize:
Be used for narrow welding space self-cooled gas protective welding gun rifle body assembly, comprise nozzle and ignition tip, it is characterized in that ignition tip connects an end of ignition tip support, the other end of ignition tip support connects the conduction bend pipe, ignition tip and ignition tip support axially extending bore form wire feed, plenum duct with the conduction bend pipe, ignition tip support overcoat insulation shunting cover, nozzle are connected in outside the insulation shunting cover;
Described conduction bend pipe outer wall integral loop bag injection moulding insulating sheath;
Circumferentially have the equal qi-emitting hole of two rows on the described ignition tip support, connectivity slot is axially established at the intermediate flange position of two steam vents;
The inwall of described insulation shunting cover is provided with helicla flute, and outer wall also is provided with helicla flute, and the helicla flute of inside and outside wall is communicated with by some pores;
The inwall of described nozzle axially has some straight troughs with the position that insulation shunting cover cooperates.
Ignition tip support one end external screw thread is connected with the conduction bend pipe, and other end internal thread is connected with ignition tip.Insulation shunting cover inwall is the rectangular thread groove, and outer wall is to mill wherein one double end rectangular thread, and the bottom of thread of inwall and the bottom of thread of outer wall have some pores that communicate.The position that nozzle is connected with insulation shunting cover is provided with the double end rectangular thread that cooperates with the double end rectangular thread of shunting the outer wall that overlaps of insulating.Nozzle is selected chromium zirconium copper for use, and insulation shunting cover is selected refractory glass fibre for use.
Protective gas enters ignition tip carriage center hole along conduction bend pipe inner chamber, and air flue is divided into two-way; One tunnel first steam vent that goes out the ignition tip support enters insulation shunting cover spiral inner wall groove, and axial pass trough imports in the nozzle cushion chamber on ignition tip support external diameter intermediate flange, and the ignition tip support is cooled off; Gas enters in the outer wall helicla flute through the bottom land pore simultaneously in the spiral inner wall groove of insulation shunting cover, imports cushion chamber through nozzle chamber screw thread and axial straight trough, and insulation shunting cover and nozzle are cooled off; Second steam vent of another route ignition tip support directly ejection enters the nozzle cushion chamber, thereby realizes effectively cooling.The conduction bend pipe that can extend as required in addition makes welding gun can arrive the weld zone in narrower welding space.
The utlity model has following beneficial effect: solved a narrow welding spacing high-temperature preheating environment welding difficult problem, operation is than safe ready, and reliable welding quality has certain popularization value; And the utility model is worn a flexible pipe by replacing and can be realized being connected fast with the gooseneck type welding gun.
