Abstract

Disclosed is a laser nozzle for metal powder laser forming. The laser nozzle for metal powder laser forming comprises an inner pipe. A laser channel is formed in an inner cavity of the inner pipe, a powder conveying sleeve, a gas flow sleeve and an outer cooling sleeve are arranged outside the inner pipe in sequence in a sleeving mode, a powder channel is formed between the inner pipe and the powder conveying sleeve, and a gas channel is formed between the powder conveying sleeve and the gas flow sleeve, and the inner pipe, the powder conveying sleeve, the gas flow sleeve and the outer cooling sleeve are coaxially arranged. A condensing lens is installed at the upper end of the laser channel. A powder inlet is formed in the upper end of the powder channel, and a powder outlet is formed in the tail end of the powder channel. A gas inlet is formed in the upper end of the gas channel, a gas outlet is formed in the tail end of the gas channel, and the tail end of the outlet of the laser channel, the tail end of the powder outlet and the tail end of the gas outlet are located on the same plane. The laser nozzle for metal powder laser forming is simple in structure, reasonable in design and stable in product quality, and convenient to operate, lasers, gases and powder are sprayed through the nozzle at the same time, manufactured metal parts have excellent quality, and the dimensions can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of metal powder laser forming equipment, in particular to a laser nozzle for metal powder laser forming. Background technique [0002] Laser is one of the great inventions of natural science in the 20th century. Since the birth of the world's first laser in 1960, in the past 50 years, laser technology has been widely used in almost all fields of national defense, science and technology, industry, agriculture, medicine, and daily life with its unique characteristics and strong vitality. rapid development and wide application. Traditional metal powder laser forming nozzles have a complex structure, poor powder ejection effect, and unstable quality of metal powder laser forming. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a laser nozzle for metal powder laser forming with simple structure and good...
