Description

Multi-function welding gun

The utility model relates to a kind of various material heating, multi-functional welding gun of welding of being used for.

In recent years, various welding guns have appearred on the market, a class is that the butane gas cylinder that adopts external lighter to use provides the method for fuel to heat, weld in these welding guns, another kind of is to adopt the fuel storage container to be set in welding gun to provide the method for fuel to weld, to heat, and used fuel also is the butagas in the lighter gas cylinder.Its weak point of the miniature welding gun of these several classes is: 1. its welding gun inside does not all have automatic ignition device, must add kindling material during use and ignite, and uses inconvenience, and security is not good enough; 2. owing to all adopt the butane price that acts as a fuel more expensive, empty bottle with after can't add fuel and can only abandon, cause waste; 3. the welding gun body adopts volume cutting torch bigger than normal or welding torch more, carries inconvenience; 4. has only a kind of boundling flame heat mode, large tracts of land work poor effect.

The utility model is at above-mentioned the deficiencies in the prior art part, provide a kind of volume the small and exquisite multi-functional welding gun that is easy to carry and has automatic firing function, and be equipped with that heating plate can produce boundling flame and garden shape adds thermal-flame, the employing liquefied petroleum gas acts as a fuel, fuel in its gas cylinder uses up the back and relies on special-purpose filling apparatus to cooperate with cylinder for liquefied gas and can carry out fuel interpolation work to gas cylinder, and is safe, convenient and practical.

For achieving the above object, the utility model adopts the welding gun body of pistol type moulding so that grip, on the rifle body, installed piezoelectric ceramic electric, and the ignition lead of piezoelectric ceramic electric passed cause igniting place in the heating tube, utilize filter to remove fuel impurity, be able to fully atomizing ejection after making fuel through the porous atomizer, therefore the dying fire flame that produces temperature height not only, and air-flow is big, be difficult for stopping up orifice, the high pressure multi beam air-flow after the atomizing mixes with air and delivers to the heating mouth of pipe, and it is lonely to run into electricity, promptly ignited, formed boundling shape dying fire.And be equipped with heating plate, when needed, heating plate screwed on the heating mouth of pipe, can obtain large-area garden shape and add thermal-flame.

For making gas cylinder can repeat postcombustion, therefore, being provided with the sheet metal that has breach on gas cylinder can cooperate with special-purpose filling apparatus, utilizes household liquified gas cylinder postcombustion.

The rifle body links to each other with decompressor by the air guide sebific duct, and decompressor is a needle-valve, and metering pin valve is cut pressure and the flow of delivering to the fuel in the rifle body with accent as required.

Decompressor links to each other with fixture, and fixture is a metal dish, and two metal claws are arranged on the metal dish, can snap on the notched sheet metal on the gas cylinder, makes the gas cylinder pin be the pressurized exhaust condition.

Special-purpose filling apparatus is made up of metal can mouth and the knob and the sealing gasket that are installed on the metal can mouth, and also have with fixture in the metal dish of metal dish same structure, knob can screw in the cylinder for liquefied gas angle valve, to the gas cylinder postcombustion.

Fig. 4 is the structural representation of the utility model gas bomb.

Fig. 5 is the structural representation of the utility model filling apparatus.

Following structure accompanying drawing is described a specific embodiment of the present utility model in detail:

Shell on the welding gun body (4) is made by bakelite or flame retardant plastics; tubulature (6) is housed on it; fuel is delivered in the filter (5) by (6); filter has the filtration sponge in (5); fuel after the filtration is delivered to needle-valve (7); by needle-valve (7) control gas flow; knob part on the needle-valve (7) is exposed at outside the shell; so that regulate; needle-valve (7) is delivered to fuel in the porous atomizer (3); porous atomizer one end has 2-3 orifice; diameter is between 0.2 millimeter-0.3 millimeter; fuel and atomizing also back form the multi beam atomization air flow; and ejection at a high speed; mix the formation gaseous mixture with air; the vortex cone (1) that arrives in the heating tube (2) is located; form the eddy current air-flow; when pulling plate machine (9); piezoelectric ceramic electric (8) is pulled the trigger, passes in the heating tube (2) and causes the eddy current gas outlet owing to get angry lead (10), thereby; gaseous mixture just can ignite; form the dying fire flame of boundling shape, also be with earthenware (11) on the ignition lead, its effect is a guardwire; heat insulation; insulation.When heating plate (12) screws in the heating tube outlet side, can obtain garden shape large tracts of land and add thermal-flame.

Gas cylinder (17) is 1 millimeter quality steel plate by wall thickness and forms through high-frequency welding, which is provided with notched sheet metal (16), two metal claws (15) on the metal dish (14) link to each other with metal dish (14), in the needle (20) on the gas cylinder (17) is taken hole (19) on the metal dish by force and during Rotate 180 °, metal claw (15) on the metal dish just is stuck under the sheet metal (16), makes gas cylinder needle (20) keep exhaust condition.Fuel is delivered in the welding gun body through metal dish (14) and the Pressure reducing needle valve (18) and the wireway (13) that link to each other with metal dish, and metering pin valve (18) can be controlled the fuel flow rate and the pressure of output.

During postcombustion, needle on the gas cylinder (20) is pressed in the hole (24), and the metal claw on the metal can mouth (25) is snapped on the sheet metal (16), knob (22) is screwed in the cylinder for liquefied gas, simultaneously cylinder for liquefied gas is inverted, can fill it up with fuel in 3-5 minute, the effect of sealing gasket (21) is to prevent that connecting place from leaking.

The utility model compared with prior art has the following advantages and effect:

1, the fuel price that uses is low. Employed fuel is liquefied petroleum gas, only reaches 1/10 of butane price.

2, igniting rapidly, reliably. Ignite owing to adopted piezoelectric ceramic electric to light a fire, its impact life-span can reach 3-5 ten thousand times, and lighting rate can reach 95%.

3, add fuel safety, convenient. The fuel that the utility model adopts is liquefied petroleum gas, is the hydrocarbon mixture that C3, C4 form, and is 400 * 10 in normal temperature normality downforce⁴－1000×10 ⁴Pascal, and the utility model has been owing to adopted special-purpose gas cylinder as the fuel storing container of miniature welding gun, container is 1 millimeter priming sheet by wall thickness and makes through high-frequency welding, so its container is withstand voltage reaches 2000 * 10⁴－3000×10 ⁴Pascal, thereby the safety when having guaranteed to utilize cylinder for liquefied gas that gas cylinder is added fuel, and designed the special fuel filling apparatus of structure uniqueness, can easily finish postcombustion work.

4, volume small and exquisite, be easy to carry, use safety. Welding gun body external form of the present utility model is the pistol type moulding, thereby small and exquisite, the compact conformation of rifle body. Be convenient to grip, carry and light a fire; Combustion tube is arranged on rifle body front end, thereby has guaranteed the safety of igniting use time spent.

5, applied widely. Heating tube of the present utility model can spin mutually and separate as required with heating plate, therefore can select to add according to the different objects heating surface (area) (HS shape of thermal-flame, produce boundling flame or garden shape flame, so function is many, and is applied widely.
