Embodiment Construction

[0030] DRAWINGS The present invention will be further described, to enable those skilled in the art to more clearly understand the invention, but without thereby restricting the scope of the present invention.

[0031] Append figure 1 , The coaxial annular beam of the present invention is a multi-powder nozzle, comprising: a water intake 1, the core 2, the connection base 3, a first sealing ring 4, the second seal ring 5, a screw 6, water outlet 7 powder feed tube 8, body 9, the light blocking plate 10, threaded sleeve 11, the housing 12 and the separating baffle plate 13.

[0032] The body 1 is connected with the water inlet and a water outlet 7. In particular the inlet connection and a water outlet 7 has an external thread, the fitting body 9 with an internal thread of the bore hole, the inlet connection and the water outlet 7 of the body 1 by a threaded connection 9, 1 and the inlet connection and the water outlet 7 are connected to both sides of the main body 9. Said inner cor...

Abstract

The invention provides a coaxial annular multi-beam powder feeding nozzle. The coaxial annular multi-beam powder feeding nozzle comprises a water filling connector, an inner core, a water dischargingconnector, a powder feeding pipe, a main body and a shell; the inner core is installed in the main body, the water filling connector and the water discharging connector are connected to the main body,and an annular water channel communicating with the water filling connector and the water discharging connector is formed between the main body and the inner core; the powder feeding pipe is connected to the main body, and an annular powder-gas mixed flow cavity communicating with the powder feeding pipe is formed between the main body and the inner core; and the shell is installed on the main body, and a powder spraying cavity communicating with the annular powder-gas mixed flow cavity is formed between the shell and the main body. According to the coaxial annular multi-beam powder feeding nozzle, by innovatively arranging a powder feeding nozzle structure, the utilization rate of powder and laser is increased, the powder feeding smoothness is improved, the powder blocking rate is reduced, the nozzle structure is simple and reliable, and the problem of the development bottleneck of existing coaxial laser cladding technology is solved.

Description

Technical field [0001] The present invention relates to laser cladding, and in particular, to a multi-beam coaxial annular powder nozzle. Background technique [0002] Corrosion is mainly due to mechanical parts equipment damage, corrosion merits parts directly related to the ability of the safe operation of mechanical equipment, laser cladding alloy powder in the surface is a recently developed anti-corrosion technology, but the use of alloy powder coaxial laser cladding powder feeding instability there, blocking the powder, the powder is low utilization problems. [0003] Powder nozzle is one of the main influence the quality of the powder feeding, the current is divided into two main nozzle, i.e. the nozzle and an annular powder feeding nozzle multibeam feed powder, powder annular feeding nozzle laser and high utilization of powder, but the powder feeding from short and prone to blocking powder; multibeam powder nozzle distance powder feeding, powder blocking rate, but the use...
