Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with specific embodiments.

[0038] A nozzle of a laser cladding device based on 3D printing, the nozzle 5 is a metal 3D printing nozzle, including a powder flow channel 51, a cooling structure 52 and an air path structure 53; the powder flow channel 51, cooling structure 52 and The gas path structure 53 is not interconnected, and is integrated inside the nozzle 5, which is integrally formed by metal 3D printing technology;

[0039] Such as image 3 As shown, the powder flow channel 51 will control the position and size of the powder spots after the powder converges. The angle between the outlet direction of the powder flow channel 51 and the vertical direction is 23°, and the distance between the powder convergence point and the bottom plane of the powder flow channel 51 is Z Between 6-10mm, to prevent the nozzle from overheating during cladding and causing powder clogging;

[0040] Such a...

Abstract

The invention provides a laser cladding device based on 3D printing and a spraying nozzle of the laser cladding device. The laser cladding device comprises a collimator, a focusing reflecting structure, a protecting structure, an adjusting structure and the spraying nozzle, wherein the collimator is coaxially connected with the incidence light path direction of the focusing reflecting structure; the focusing reflecting structure is coaxially connected with protecting structure in the emitting light path direction; and the protecting structure, the adjusting structure and the spraying nozzle are mutually coaxial from top to bottom and are coaxially connected in a sealed mode through screws. The spraying nozzle comprises a powder flow channel, a cooling structure and an air path structure, and the powder flow channel, the cooling structure and the air path structure do not communicate with one another and are integrally formed with a metal 3D printing technology. Machining and installation of the cladding device and the spraying nozzle are simplified, the cooling area of the spraying nozzle is effectively increased, the later-stage machining treatment can be performed on the integrated spraying nozzle, and workpiece oxidization of the cladding process is reduced.

Description

technical field [0001] The invention relates to the field of laser cladding, in particular to a 3D printing-based laser cladding device and a nozzle thereof. Background technique [0002] Laser cladding means that the selected coating material is added to the surface of the substrate by different methods, and the coating material and the surface of the substrate are fused and rapidly solidified by using a high-power density laser beam, thereby forming a wear-resistant, corrosion-resistant, and anti-corrosion coating. Oxidized metallurgically bonded surface coating. It is mainly used in the fields of laser repair and remanufacturing technology and additive forming technology. [0003] The laser cladding process puts forward higher requirements on the cladding device, especially the nozzle part. The heat generated when the laser acts on the optical accessories and coating materials requires the device to be equipped with a cooling function; the dust is serious during the wor...
