Existing laser melting coating also lacks protection gas tail with side direction powder-feeding nozzle device and blows function, is therefore difficult to avoid the sticky powder of cladding alloy layer; And the protection letter shoot that adopts with side direction powder-feeding nozzle device of existing laser melting coating and powder delivering pipe point be arranged, make the pipeline of the production plant originally blocking up with regard to pipeline arrange more complicated.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of laser melting coating side direction powder-feeding nozzle device, its object: the quick cooling cladding alloy layer of protection gas energy, and there is protection gas tail and blow function, adopt the synchronous transport pipe of protection gas and powder.
For achieving the above object, the technical solution of the utility model is as follows:
Side direction powder-feeding nozzle device for a kind of laser melting coating, comprise upper casing, lower casing, binding, shower nozzle and transfer lime, upper casing is provided with protection gas joint, upper casing is arranged on the top of lower casing, the lower end of described lower casing is provided with the outlet of protection gas, in lower casing, be provided with fixture block, binding is arranged on fixture block, and binding is provided with protection gas port;
Described shower nozzle is fixed on upper casing and binding, and one end of shower nozzle is provided with the powder joint that protrudes from upper casing, and the other end is provided with the powder nozzle being in the outlet of protection gas, between powder joint and powder nozzle, is provided with powder channel;
Transfer lime is arranged on the protection gas joint and powder joint of upper casing, and transfer lime is provided with the powder passage communicating with the protection gas passage of protecting gas joint to communicate with powder joint.
Preferably, the outside of transfer lime is provided with fire retardant jacket, between fire retardant jacket and gas passage and powder passage, is provided with aramid yarn stiffener.
By technique scheme, this laser melting coating adopts the synchronous transport pipe of protection gas and powder with side direction powder-feeding nozzle device, has reduced the demand of pipeline wiring; The brushing at cladding alloy layer a large amount of protection gas high speeds by the protection gas joint of upper casing and the outlet of the protection gas of lower casing, make to protect the quick cooling cladding alloy layer of gas, weakened the degree of oxidation of the powder in the cladding course of processing, and make on cladding alloy layer not can adhesion material powder, there is protection gas tail and blow function; Protection gas at a high speed has also improved the degree that converges of material powder, thereby has improved the material utilization ratio of powder and the working (machining) efficiency of laser.
