Embodiment 1

[0040] Example 1: The working process of using a highly adaptable anti-oxidation laser cladding device for laser additive non-ferrous metals is as follows: first connect the water-cooled pipeline, turn on the laser nozzle 1, connect the inert gas protection pipeline, and continuously feed high-purity argon Gas or nitrogen protective gas, the inert gas first enters from the first protective gas channel of the laser shower head 1, and then enters from the protective gas inlet 9 to form an air curtain together. By testing the oxygen content of the air pressure relief channel 10, it is judged whether the air is completely discharged. ; Second, wait for 1 to 2 minutes until the ambient atmosphere is stable; secondly, carry out local atmosphere laser additive work, adjust the powder feeding speed, test the cleaning function, and perform laser additive non-ferrous metals in an inert atmosphere according to the program instructions.

Embodiment 2

[0041] Example 2: The working process of using a highly adaptable anti-oxidation laser cladding device for laser additive non-ferrous metals is as follows: first, install the device, judge that the environment requires opening or dismantling the door 12, and will require partial repair or non-ferrous metal cladding Partially put it into the opening, and then rotate the protective cover according to the environmental requirements to adapt to the deformation, and finally carry out the sealing operation, and attach the magnetic parts to the surface of the workpiece to form a sealed space. If it cannot be completely fitted, the air curtain formed by the inert gas can be used to remove the air first. Then move to the surface of the workpiece, and then pass inert gas for 2 to 3 minutes to form a protective gas atmosphere, and then carry out specific repair or laser cladding work.

[0042] This highly adaptable anti-oxidation laser cladding device has the following advantages: (1) Clo...

Abstract

The invention relates to a high-adaptability anti-oxidation laser cladding device. The high-adaptability anti-oxidation laser cladding device comprises a protective cover and a laser spray head at least partially arranged in the protective cover, wherein the protective cover is provided with a cover body and a bottom plate sealing the bottom of the cover body, and a laser inlet allowing the laser spray head to stretch into the cover body is formed in the top of the cover body; and the bottom plate is connected with the cover body through a connecting piece, and the bottom plate can rotate relative to the cover body in the axis direction of the cover body with the connecting piece as the rotating axis so as to open the bottom of the cover body. The high-adaptability anti-oxidation laser cladding device can adapt to the sizes of different parts, so that an expensive large-size fixed inert gas cabin does not need to be purchased, and much cost is saved; and the high-adaptability anti-oxidation laser cladding device is high in flexibility and adaptability, and capable of achieving a better anti-oxidation protection effect.

Description

technical field [0001] The invention relates to a highly adaptable anti-oxidation laser cladding device, which belongs to laser cladding and additive equipment. Background technique [0002] Copper alloy is a non-ferrous metal material with many excellent comprehensive mechanical properties. Laser cladding technology, as a new type of surface shaping modification technology, is widely used in aerospace, biomedical, and national defense technology fields. Lead bronze is a very valuable wear-resistant material. Because the soft lead particles act as a lubricant when friction is applied, lead bronze has a small friction coefficient and high wear resistance. Laser cladding technology uses laser beam radiation as a heat source to partially melt the alloy powder and the surface of the substrate alloy to form a cladding layer with good metallurgical bonding. Due to its flexible operation, low price, excellent cladding layer performance, environmental protection performance, and th...
