Abstract
The invention provides a coaxial laser cladding spray nozzle comprising a laser beam channel, inner spray nozzle cores and outer cavity water cooling layers. Inner cavity water cooling layers are arranged between the laser beam channel and the inner spray nozzle cores. A powder channel is arranged outside each inner spray nozzle core. Air inlet pipes are arranged between the powder channels and the outer cavity water cooling layers and provided with air inflow holes. The inner cavity water cooling layers and the outer cavity water cooling layers are each provided with a water inlet and a water outlet. The laser beam channel is internally provided with a focusing lens. Inert gas is introduced in the laser beam channel. The laser cladding spray nozzle is made from red copper materials. The coaxial laser cladding spray nozzle is simple in structure and good in cooling effect, and meets the requirement that a laser cladding technology requires that the size and the performance of a cladding layer should be kept consistent in various directions.
Description
Technical field
The invention belongs to laser processing application field, particularly relate to a kind of coaxial laser melting-painting nozzle.
Background technology
In laser melting coating is processed, whole dust feeder used can be divided into two parts: powder feeder and powder-feeding nozzle.
The effect of powder-feeding nozzle is the powder sent here from powder feeder circulation to be become different shapes and send in laser beam,
Realize the processing needed.The structure of powder-feeding nozzle and performance directly affect whole processing effect.Current one side is sent
Powder nozzle, it be limited in that powder feeding direction only one of which, it is impossible to meet laser melting and coating technique requirement cladding layer
Size prolong the requirement that all directions should keep consistent with performance.
Summary of the invention
The present invention is just for above technical problem, it is provided that a kind of coaxial laser melting-painting nozzle.
The present invention for achieving the above object, by the following technical solutions: a kind of coaxial laser melting-painting nozzle, including
Laser beam passway, inner nozzle core and exocoel water-cooled layer, be provided with inner chamber water-cooled between laser beam passway and inner nozzle core
Layer, is provided with powder body passage, is provided with air inlet pipe, air inlet between powder body passage and exocoel water-cooled layer outside inner nozzle core
Pipe is provided with on air inlet, inner chamber water-cooled layer and exocoel water-cooled layer and is designed with water inlet and outlet.
Focus lamp is installed in described laser beam passway, and is connected with noble gas.
Described coaxial laser melting-painting nozzle uses red copper material to make.
Compared with prior art, the invention has the beneficial effects as follows: the present invention uses bilayer to cool down, good cooling results,
And coaxial laser melting-painting nozzle meets the size of laser melting and coating technique requirement cladding layer and performance prolongs all directions
Consistent requirement should be kept.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
As it can be seen, a kind of coaxial laser melting-painting nozzle, including laser beam passway 1, inner nozzle core 2 and exocoel
Water-cooled layer 7, is provided with inner chamber water-cooled layer 3 between laser beam passway 1 and inner nozzle core 2, inner nozzle core 2 is outside
It is provided with powder body passage 4, is provided with air inlet pipe 5 between powder body passage 4 and exocoel water-cooled layer 7, air inlet pipe 5 sets
Have on air inlet 6, inner chamber water-cooled layer 3 and exocoel water-cooled layer 7 and be designed with water inlet 8 and outlet 9.
In described laser beam passway 1, focus lamp is installed, and is connected with noble gas.
Described coaxial laser melting-painting nozzle uses red copper material to make.
The present invention uses double-deck cooling, and the working time being possible not only to improve nozzle the most effectively avoids due to spray
Mouth deformation under the influence of high temperature and make the situation of powder blocking meal outlet;And powder body passage 4 and exocoel water-cooled
It is provided with the air inlet pipe 5 with air inlet 6 between layer 7, forms the powder flow inside gas curtain protection, realize powder
The height of body converges and preferably prevents the dispersion of powder body.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by above-mentioned
The restriction of mode, if the various improvement that the method design that have employed the present invention is carried out with technical scheme, or without
Improve and directly apply to other occasion, all within protection scope of the present invention.
