Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding, and in particular to a laser cladding device for roller repair. Background Art

[0002] Laser Cladding, also known as laser melting or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base by adding cladding material to the surface of the base material and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the base material.

[0003] Through synchronous or pre-placed materials, external materials are added to the molten pool formed by laser irradiation of the substrate, and the two are quickly solidified together to form a coating layer. The cladding layer has low dilution but strong bonding force, and is metallurgically bonded to the substrate, which can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance or electrical properties of the substrate surface, thereby achieving the purpose of surface modification or repair, meeting the specific performance requirements of the material surface while saving a lot of material costs. Compared with surfacing, spraying, electroplating and vapor deposition, laser cladding has the characteristics of low dilution, dense organization, good bonding between coating and substrate, many suitable cladding materials, and large changes in particle size and content. Therefore, the application prospects of laser cladding technology are very broad.

[0004] From the current application of laser cladding, it is mainly used in three aspects: first, surface modification of materials, such as gas turbine blades, rollers, gears, etc.; second, surface repair of products, such as rotors, molds, etc. Relevant data show that the strength of the repaired parts can reach more than 90% of the original strength, and the repair cost is less than 1 / 5 of the replacement price. More importantly, it shortens the maintenance time and solves the problem of rapid repair of rotating parts that must be solved for the continuous and reliable operation of major complete sets of equipment in large enterprises. In addition, laser cladding of super wear-resistant and corrosion-resistant alloys on the surface of key components can greatly improve the service life of components without deformation of the surface of components; laser cladding of the mold surface can not only improve the strength of the mold, but also reduce the manufacturing cost by 2 / 3 and shorten the manufacturing cycle by 4 / 5. Third, laser additive manufacturing. Through synchronous powder feeding or wire feeding, laser cladding is carried out layer by layer to obtain components with three-dimensional structure.

After the rollers are clad, the rollers need to be removed and replaced with other non-processed rollers for installation and cladding. In view of this, a laser cladding device for roller repair is developed. Utility Model Content
