The utility model automatic welder(welding machine) is simple in structure, easy to make with air supply system.Use this automatic welder(welding machine) with air supply system be to nuclear island in the narrow gap welding mouth of the main pipeline automatic welder(welding machine) that carries out automatic welding welding while supplying protective gas; do not need the protection gas cylinder that protection gas is housed to be carried near automatic welder(welding machine) body; manpower and materials are saved; and can avoid protecting gas cylinder to take activity space, facilitate staff to work.Adopt flexible pipe as gas pipeline, staff can be according to the using area of this air supply system gas pipeline of arbitrarily arranging, easy to use.
Accompanying drawing explanation
Fig. 1 is that the utility model automatic welder(welding machine) air supply system is in using the schematic diagram of state.
The specific embodiment
As shown in Figure 1, the utility model automatic welder(welding machine) comprises gas cylinder group 11 and gas pipeline 12 with air supply system 1.Wherein, gas cylinder group 11 is connected and is formed by multiple protection gas cylinders 111.The inlet end of gas pipeline 12 is connected with the gas outlet of gas cylinder group 11 by jointing 121, the outlet side of this gas pipeline 12 is connected with the air inlet on the automatic welder(welding machine) body 21 welding in the automatic welder(welding machine) 2 of use by jointing 121, so that gas cylinder group 11 is communicated with automatic welder(welding machine) 2.On gas pipeline 12, be disposed with Pressure gauge 13, pressure-reducing valve 14, detection flowmeter 15 in normally open from its inlet end to outlet side and regulate with flowmeter 16, and detect and use flowmeter 15 near gas cylinder group 11, regulate with flowmeter 16 near automatic welder(welding machine) body 21.
The stream pressure forming in the import department of gas pipeline 12 when Pressure gauge 13 flows out from gas cylinder group 11 for detection of the argon helium gas mixture in gas cylinder group 11, so that observe the stream pressure entering in gas pipeline 12, and then regulate as required stream pressure, the pressure being born to reduce gas pipeline 12.Pressure gauge 13 can also be for detection of the content of the interior argon helium gas mixture of gas cylinder group 11; so that the argon gas gaseous mixture in gas cylinder group 11 stops welding before using up, and then avoid affecting welding quality because not having argon helium gas mixture to weld to protect on automatic welding in the time carrying out automatic welding welding.
Pressure-reducing valve 14 reduces pressure to the air-flow that enters gas pipeline 12 for the stream pressure of the argon helium gas mixture flowing out from gas cylinder group 11 that detects according to Pressure gauge 13.That is to say, in the time that Pressure gauge 13 detects that from gas cylinder group 11 stream pressure of the argon helium gas mixture flowing out is excessive, this air-flow is reduced pressure with pressure-reducing valve 14, to reduce the entering stream pressure in gas pipeline 12, and then avoid, because the stream pressure in gas pipeline 12 is excessive, this gas pipeline 12 is caused to damage.
Detect the air-tightness for detection of this air supply system 1 with flowmeter 15; so that find in time whether have gas leakage point in this air supply system 1 in the time using this air supply system 1 to automatic welder(welding machine) 2 air feed; in the time there is gas leakage point; staff can find out position the enforcing remedies measure at gas leakage point place in time; to avoid causing the shielding gas flow that forms at welding gun 22 places of automatic welder(welding machine) 2 unstable because air supply system 1 leaks gas, and then the narrow gap welding mouth welding that reduces main pipeline 3 produces the risk of weld defect because shielding gas flow is unstable.Concrete detection method is as follows: first close automatic welder(welding machine) 2, then the gas outlet of gas cylinder group 11 is opened, and make automatic welder(welding machine) 2 keep closed condition, observe and detect with flowmeter 15.In the time that this detection is 0 with the reading of flowmeter 15, in this air supply system 1, there is no gas flow, in this air supply system 1, there is not gas leakage point; In the time that this detection is not 0 with the reading of flowmeter 15, in this air supply system 1, there is gas flow, in this air supply system 1, there is gas leakage point.
Regulate with flowmeter 16 for need to regulate the flow of the argon helium gas mixture that air supply system 1 exports to automatic welder(welding machine) 2 according to welding, to avoid in automatic welding welding process because shield gas flow rate is excessive or the too small weld defect that produces, and then raising welding effect.
Be provided with total air outlet valve 112 at the gas outlet place of gas cylinder group 11.Before use, the air outlet valve (not shown) on all protection gas cylinders 111 in gas cylinder group 11 is all opened, total air outlet valve 112 cuts out.Like this, only need open this total air outlet valve 112 in use, and need not one by one the air outlet valve on all protection gas cylinders 111 in gas cylinder group 11 be opened again; In the time stopping using, only need close total air outlet valve 112, and need not one by one the air outlet valve on all protection gas cylinders 111 in gas cylinder group 11 cut out again, facilitate staff to operate.
Gas pipeline 12 in air supply system 1 adopts flexible pipe to make, like this, using this air supply system 1 during to automatic welder(welding machine) 2 air feed, can be according to the using area gas pipeline 12 of arbitrarily arranging, as long as the port of export of this gas pipeline 12 is connected with the air inlet of automatic welder(welding machine) body 21, easy to use.This flexible pipe is preferably with the oxygen hose in oxygen-acetylene pipe, and this oxygen hose can have been bought from the market.Such gas pipeline 12 is high pressure resistant, stretch-proof, acid and alkali-resistance, corrosion-resistant, soft light, durable in use.
Gas cylinder group 11 is connected and is formed by 12 protection gas cylinders 111.Like this; the 11 crane on vehicle handling gas cylinder groups that both can directly adopt the transport vehicle of transportation protection gas cylinder to be equipped with; and need not be equipped with in addition loop wheel machine; facilitate loading, the unloading of gas cylinder group 11; can reduce welding job personnel again and change the number of times of gas cylinder group 11; easy to use, and reduced welding job personnel's workload, save welding consuming time.
