Description
Technical field
The utility model relates to a kind of field of welding devices, relates in particular to a kind of argon-arc welding gun.
Background technology
It mainly divides air cooling (air cooling) and water-cooled two classes the welding gun of argon tungsten-arc welding at present, and the latter is for large welding current.But water cooled welding torch exposes some problems gradually, is mainly:
1) water source, production scene is limited, and some hot jobs can not in time complete;
2) welding gun argon gas guard shield protected area is little, during welding, need to have the people to drag cover protection with argon gas, that is: in the operation process, and people's welding, personal dragging covers on the protection of weld seam back; This technique is applicable to the place operation, and industrial enterprise production scene narrow space often, double operation inconvenience is implemented;
3) the welding gun venthole is few, and nozzle is less, and in welding process, when large-minded, it is excessive that high pressure causes argon gas to blow power, loses other protective effects, thereby cause the weld seam embrittlement, reduces the corrosion resistance of weld seam; Argon gas amount hour, can't play the gas shield effect again, is difficult to equally guarantee weldquality.
The utility model content
In order to solve above-mentioned the deficiencies in the prior art, it is a kind of to alleviate the air feed uneven phenomenon that causes because of air pressure change, cost-effective argon-arc welding gun again that the utility model provides.
A kind of argon-arc welding gun of the present utility model, comprise tungsten electrode, tungsten electrode chuck, air inlet pipe joint, step up nut, buffer air chamber, handle, seal washer and ceramic nozzle; Described standby tight nut, seal washer, buffer air chamber are connected successively with ceramic nozzle, described tungsten electrode is enclosed within the tungsten electrode chuck, described tungsten electrode chuck passes buffer air chamber and seal washer, thereby and with standby tight nut, be threaded and make to form sealed air chamber between seal washer and buffer air chamber; Described gas-tpe fitting is connected with air chamber; Described handle is connected with buffer air chamber, in the outer felt of described buffer air chamber, handle and ceramic nozzle, is wound with insulating tape; The bottom of described air chamber is provided with 8 ventholes that are communicated with ceramic nozzle, and the internal diameter of described ceramic nozzle is 16mm.
In above-mentioned argon-arc welding gun, the inlet end of described air inlet pipe joint is provided with the groove of hangnail structure.
In above-mentioned argon-arc welding gun, the material of described tungsten electrode chuck, standby tight nut, buffer air chamber and air inlet pipe joint is brass.
In above-mentioned argon-arc welding gun, also comprise electrician's wiring card, described electrician's wiring card is arranged in handle, and welds with buffer air chamber.
Argon-arc welding gun of the present utility model increases the argon gas buffer air chamber by arranging, and increases venthole quantity, to alleviate the air feed uneven phenomenon that causes because of air pressure change, can not make cable temperature overheated; Increase the internal diameter of ceramic nozzle with area increased; reach the purpose that strengthens the argon shield zone; without being set, argon gas drags cover; provide cost savings, thereby the power supply scheme of alternative water-cooled cable pipe reduces the cable superheating phenomenon; remove water-cooling system; not limited by regional condition, can complete separately, usability is strong.
The accompanying drawing explanation
Fig. 1 is the structural representation of the argon-arc welding gun of the utility model embodiment;
Fig. 2 is the structural representation of the air inlet pipe joint of the utility model embodiment;
In figure, 1 is that tungsten electrode, 2 is electrician's wiring card for groove, 13 for venthole, 12 for insulating tape, 11 for handle, 9 for gas-tpe fitting, 8 for ceramic nozzle, 7 for buffer air chamber, 6 for seal washer, 5 for standby tight nut, 4 for tungsten electrode chuck, 3.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1 and Figure 2, a kind of argon-arc welding gun of the present utility model, comprise tungsten electrode 1, tungsten electrode chuck 2, air inlet pipe joint 7, standby tight nut 3, electrician's wiring card 13, buffer air chamber 5, handle 8, seal washer 4 and ceramic nozzle 6.described standby tight nut 3, seal washer 4, buffer air chamber 5 are connected successively with ceramic nozzle 6, described tungsten electrode 1 is enclosed within tungsten electrode chuck 2, described tungsten electrode chuck 2 passes buffer air chamber 2 and seal washer 4, thereby and with standby tight nut 3, be threaded and make formation sealed air chamber 9 between seal washer 4 and buffer air chamber 5, described gas-tpe fitting 7 is connected with air chamber 9, the bottom of described air chamber 9 is provided with 8 ventholes 11 that are communicated with ceramic nozzle 6, the internal diameter of described ceramic nozzle 6 is 16mm, by this structure, the argon gas of gas-tpe fitting 7 can be delivered in air chamber 9 and cushioned, in 8 pores, flow to ceramic nozzle 6 respectively again, thereby carried out the buffering of air pressure, avoided the air feed uneven phenomenon that causes because of air pressure change, can not make the overheated alternative water-cooled cable pipe of cable temperature, use more perfect, by the internal diameter of ceramic nozzle 6, be 16mm, thereby replace argon gas to drag cover, provide cost savings, not limited by regional condition, can complete separately, usability is strong.Described handle 8 is connected with buffer air chamber 5, in the outer felt of described buffer air chamber 5, handle 8 and ceramic nozzle 6, is wound with insulating tape 10.Described electrician's wiring card 13 is arranged in handle 8, and welds with buffer air chamber 5.The inlet end of described air inlet pipe joint 7 is provided with the groove 12 of hangnail structure, is convenient to tracheae and is connected with the firm of air inlet pipe joint 7.The material of described tungsten electrode chuck 2, standby tight nut 3, buffer air chamber 5 and air inlet pipe joint 7 is brass.Described electrician's wiring card 13 is arranged in handle 8, and welds with buffer air chamber 5, for connection cable.
