Description

The box-like two stations solderer of gas premixing

Technical field

The utility model belongs to gas brazing machine technical field, and in particular to the box-like two stations solderer of gas premixing.

Background technology

Traditional two station automatic brazing machines are mainly divided to two kinds, self-priming automatic brazing machine and hybrid automatic brazing machine.

The technology of the self-priming solderer use in industry is at present：By from welding gun small bore rifle core (diameter 0.5mm) The natural gas with pressure is ejected, while burning is sprayed at pipette tips after gun barrel mixes from sucking portion of air, to work Part is heated.

The defect and deficiency of this self-priming automatic brazing machine：

1. natural gas cannot fully burn, flame ejection dynamics is small, and shape is unstable, and temperature is undesirable, to welding production Kind class is restricted, and welding product disqualification rate is high；

2. flame temperature is easily by gas pressure influence of fluctuations, stability is poor；

3. flame profile is easily influenced by flow of external air, aligned environment requires height, operating personnel that can not use air-conditioning, electricity Fan etc.；

4. existing welding gun rifle core because the volatilization of scaling powder easy tos produce clogging, need to regularly replace rifle in production Core.

The technology of the hybrid two stations solderer use in industry is at present：Respectively by adjusting combustion gas and air (oxygen Gas) flow, mix using gun barrel after so that combustion gas and air is formed certain proportion, finally lighted in muzzle.

The defect and deficiency of two station solderer of conventional hybrid formula：

1. air and combustion gas are required to be conveyed in the case where there is pressure, to the stabilization of air pressure and gaseous-pressure Property require it is higher, if pressure has fluctuation that will directly affect the stability of flame.

2. Gas Pipe route does not have check-valves, there is the risk that flame reflux gas explosion occurs.

3. pipeline is more complex, every welding gun to be both needed to a set of regulating valve is separately configured, inconvenience is unified to be adjusted.

4. since equipment pipeline is more complex, every solderer can only generally configure 4 welding guns, influence to be brazed improved efficiency.

Utility model content

Poor, safety difference that purpose of the utility model is to solve stability existing in the prior art and efficiency are low The problems such as, a kind of stability height is provided, it is efficient convenient for control, consume the box-like two stations solderer of low gas premixing.

To achieve the above object, technical solution used by the utility model is：The box-like two stations solderer of gas premixing, Including mixing tube, described mixing tube one end connects branching block, and one end connects air hose, and the mixing tube is also associated with Gas Pipe, The Gas Pipe is equipped with zero-pressure valve, and the uninterrupted of fuel gas passes through the adjusting that is arranged on air hose in the mixing tube Valve is adjusted.

Preferably, the lower section of zero-pressure valve is also equipped with pressure reducing valve, gas filter and solenoid valve successively in the Gas Pipe.

Preferably, the air hose external compressed air, the air hose pass through after the first needle-valve and the first solenoid valve points For two-way, the second needle-valve is connected all the way, connects second solenoid valve all the way, is then converged again to enter mixing tube all the way.

Preferably, the external wind turbine of the air hose, the air hose are divided into two-way, connect pneumatic ball valve all the way, connect all the way Manual ball valve is connect, is then converged again to enter mixing tube all the way.

Preferably, the gas mixed is divided into four tunnels and enters welding gun by the branching block.

Preferably, the zero-pressure valve has check function.

Preferably, the pressure reducing valve is by gas pressure-reducing to 0.01-0.015Mpa.
