The invention relates to an adjustable type anti-splashing wide-band
laser cladding coaxial
powder-feeding
nozzle and a manufacturing method thereof. The adjustable type anti-splashing wide-band lasercladding coaxial
powder-feeding
nozzle comprises an upper body, an intermediate body, a
lower body and a blowing mechanism. The upper body comprises a compression ring, a connecting hoop and an adjusting nut, the intermediate body comprises a positioning pin, a lifting
flange, a
gas insulation sleeve and a connecting disc, the
lower body comprises a blocking piece, a gland, a cooling water hood,an outer layer gas hood, a
powder-feeding hood, an inner layer gas hood and an end seal hood, and the blowing mechanism comprises a blowing groove block connected with an anti-splashing air hole of the lifting
flange and a blowing
pipe with the
working range covering a rectangular hole in the gland. According to the adjustable type anti-splashing wide-band
laser cladding coaxial powder-feeding
nozzle, it is ensured that a
laser protective eyewear is not polluted, powder feeding is stable and even, the powder
utilization rate of laser cladding is high, the
cooling effect is good, disassembly and
assembly are easy, the powder-feeding width and the angle are adjustable, the defocusing amount is adjusted steplessly, and the adjustable type anti-splashing wide-band laser cladding coaxial powder-feeding nozzle is suitable for wide-band type laser cladding powder feeding of various different focal lengths and
light spot sizes.
