Roulette is a kind of high-precision mechanical equipment, widely used in automotive, aerospace, petrochemical and other fields. However, in the process of long-term use, due to the influence of high temperature, high pressure, corrosion and other factors, it is easy to induce deformation, wear, cracks and other problems, affecting its normal use and accuracy. Therefore, wheel repair has become an important technical problem.
The main purpose of wheel repair is to restore its shape and dimensional accuracy while improving its surface hardness and wear resistance. In the process of repair, factors such as the material, structure and using requirements of the wheel need to be taken into account, and appropriate repair methods and materials should be selected.
In general, wheel repair can be divided into the following steps:
Preparatory work
Before repair, it is necessary to conduct a comprehensive inspection and measurement of the wheel to understand its material, structure, use requirements and other information. At the same time, it is necessary to prepare the equipment and materials required for repair, such as grinding machines, milling machines, lathes, grinding wheels, repair agents, etc.
surface treatment
Surface treatment is one of the important steps of wheel repair, including oil removal, rust removal, coarsening and other operations. In the surface treatment, it is necessary to use professional cleaning agents and roughening agents to remove impurities such as oil, rust, and oxide on the surface of the wheel, while coarsening the surface and improving the adhesion of the repair layer.
laser quenching repair
Laser quenching repair is an advanced processing technology that can significantly improve the hardness and wear resistance of the wheel, thereby extending its service life.
1. The basic principle of laser hardening wheel processing
Laser quenching is a kind of processing method that uses a high-energy laser beam to irradiate the surface of the wheel, so that it can absorb heat quickly and cool quickly. Under the irradiation of the laser beam, the surface material of the wheel is rapidly heated and reaches the melting point, and then quickly cooled to achieve the quenching effect. This processing method can achieve local quenching so that the hardness and wear resistance of the wheel can be significantly improved.
2. The advantages of laser hardening wheel processing
(1) Improve the hardness and wear resistance of the roulette disc: laser quenching roulette processing can achieve local quenching, so that the hardness and wear resistance of the roulette disc are significantly improved, thereby extending its service life.
(2) Reduce costs: compared with traditional quenching methods, laser quenching wheel processing does not require the use of cooling media, so costs can be reduced.
(3) Reduce deformation: Traditional quenching methods may lead to disk deformation, and laser quenching disk processing can precisely control the input and distribution of heat, thereby reducing deformation.
(4) Fast processing: laser quenching wheel processing has the advantages of fast and efficient, and can complete the processing of the wheel in a short time.
(5) Environmental friendly: Laser quenching wheel processing does not require the use of any chemical substances or cooling media, so it will not pollute the environment.
Laser quenching repair is the core step of wheel repair, it is necessary to choose the appropriate repair method and material according to the actual situation of the wheel. In the repair construction process, it is necessary to control the temperature, humidity, pressure and other parameters to ensure the quality and accuracy of the repair.
Postprocessing
Post-treatment is the last step of the wheel repair, including dressing, polishing, inspection and other operations. In the post-treatment process, it is necessary to use professional dressing tools and polishing agents to smooth the repaired part, while testing and verifying the repaired part to ensure that it meets the requirements of use.
Roulette repair is a highly technical work that requires professional technicians and equipment support. In the repair process, it is necessary to pay attention to safety and environmental protection issues to avoid accidents and pollution of the environment. At the same time, for different roulette and repair requirements, it is necessary to choose the appropriate repair methods and materials to ensure the quality and effect of the repair.
