Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding, in particular to an externally mounted protective device for a laser cladding nozzle. Background Art

[0002] With the development of metal material surface modification technology, laser cladding technology is more and more widely used in industrial production. Laser cladding technology refers to placing selected coating materials on the surface of the coated substrate in different filler forms, melting them and a thin layer on the substrate surface at the same time through high-energy laser irradiation, and quickly solidifying to form a surface coating with extremely low dilution and metallurgical bonding with the substrate material, thereby significantly improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate surface. During laser cladding, the high-energy laser beam will contact the substrate surface to produce high-temperature molten debris splashing, affecting the operation.

[0003] For example, the patent document with the announcement number CN220468162U discloses an external protection device for laser cladding nozzles. Through the cooperation of electromagnetic push rods, automatic grippers, springs, locking rings and other structures, a protective cover can be formed around the laser cladding nozzle during laser cladding. In addition to preventing splashing, the protective cover can also ensure the continuous action of the protective gas in the cladding area, reduce the oxidation of the molten pool, and improve the product quality of laser cladding processing; and, a protective device is installed on the laser cladding nozzle, and the metal rod on the external clamping protection mechanism is adjusted according to the size of the nozzle, which can be suitable for laser cladding heads of different sizes to play a clamping role; finally, putting on the protective cover can play a certain role in corrosion protection and dust prevention for the nozzle.

[0004] Although the above patent can use industrial fireproof cloth to block flying debris during use, a large amount of debris will stick to the industrial fireproof cloth after a period of use, and the fireproof cloth needs to be removed and cleaned in time. However, the above patent is not convenient for quick loading and unloading of the fireproof cloth during use. Utility Model Content
