Description
Technical field
The utility model relates to technical field of laser welding more particularly to a kind of laser welding protective gas conveying devices.
Background technique
Gas used in welding usually has the main protection gas of protection laser molten pool, plasma blow-out gas (in order to remove
The plasma cloud generated by thermometal steam and main protection atmosphere interaction, in case plasma generates screen to laser beam
Cover or reflect) and the tail of protection weld seam solidification drag gas (since Laser Welding Speed is very fast, main protection gas shielded model left in molten bath
Solidification completely not yet after enclosing).And in traditional technical solution, there are several types of schemes：
1. main protection gas and plasma blow-out gas share gas all the way, then integrated tail drags gas；
2. only providing plasma blow-out gas without main protection gas, tail is still further provided and drags gas；
3. main protection gas drags gas to be integrally designed with tail, plasma blow-out gas is still further provided.
These three schemes have the shortcomings that respective：
1. plasma blow-out gas with main protection gas due to using with gas all the way, and main protection throughput cannot be excessive, therefore
Plasma blowing throughput is also smaller, and effect is poor；
2. throughput is larger, and protective device occupied space is also larger, and tail is caused to drag gas from molten bath although plasma is blown down
Farther out, effective protection can not be provided to molten bath；
3. plasma blow-out gas can generate interference to main protection gas, and need extra means, complex.

Side, rear end extend to ontology rear end, and the air taking port is connected to plasma blow-out gas gas source, and the window of supplying gas is connected to main protection
Gas and tail drag gas gas source.
Further, the air taking port level is supplied gas, and the shape of the air taking port is one of circle, diamond shape, the flat degree of lip-rounding
Or it is a variety of.
Further, three angled vertical planes are arranged in the ontology front end, send described in setting one on each vertical plane
Port, three air taking ports are in same level.
Further, three air taking port connectors of side's setting, three air taking port connectors are respectively connected to three on the body
Air taking port, three air taking port connectors are connected to the plasma blow-out gas gas source by pipeline, on the body side's setting two
A window connector of supplying gas, two window connectors of supplying gas are connected to window of supplying gas, and two window connectors of supplying gas are connected to the main guarantor by pipeline
Shield gas and tail drag gas gas source.
Further, equal drift net is set below the window of supplying gas.
Further, setting adjustment in side's is bound round on the body.
The utility model has the beneficial effects that：
(1) three kinds of protective gas needed for Laser Welding are integrated into set of device；
(2) plasma blows down being optimal of effect；
(3) plasma blow-out gas is not interfered with each other with main protection gas, and can be controlled separately flow；
(4) tail drags gas length long enough, and forms a cavity, the weldering fast especially suitable for this kind of speed of welding of Laser Welding
Method is connect, adequately protection is provided during the entire process of molten bath solidifies.

Specific embodiment
The specific embodiment of the utility model laser welding protective gas conveying device is made with reference to the accompanying drawing detailed
Explanation.
Referring to attached drawing 1,2,3, laser welding protective gas conveying device includes ontology 1, setting adjustment hoop 2 above ontology 1,
1 front end of ontology is the air taking port 3 of plasma blow-out gas, and three angled vertical planes are arranged in 1 front end of ontology, on each vertical plane
One air taking port 3 is set, and three air taking ports 3 are in same level.The shape of air taking port 3 is circle, in diamond shape, the flat degree of lip-rounding
It is one or more.Three air taking port connectors 4 are set above ontology 1, and three air taking port connectors 4 are respectively connected to three air taking ports
3, three air taking port connectors 4 are connected to plasma blow-out gas gas source by pipeline.
1 lower end of ontology is the window 5 of supplying gas that main protection gas and tail drag gas, and equal drift net 7 is arranged below window 5 of supplying gas.It supplies gas window 5
Front end is located at the underface of air taking port 3, and rear end extends to 1 rear end of ontology, two window connectors 6 of supplying gas of setting above ontology 1, and two
