Key Technologies Of Y25 Bogie Production And Quality Control

Y25 bogie frame is welded by the integral and a suspension of the freight train, light weight, flexible and good, performance good, the International Union of Railways UIC to determine the standards for the European railway freight car bogie, its speed to 120km/h. The company has introduced technology Y25 bogie, product trial and the production of European qualification. Y25 Bogie products can fill the successful trial production sector railway wagon bogie exports to the European gap, to achieve a historic breakthrough, and can generate huge economic benefits.This subject focuses on the Y25 bogie components and die bending process of design and architecture as a whole painting process were analyzed. Meanwhile, thermal cutting, wheel on the pressure equipment, testing and other techniques were brief, and made the quality of the Y25 bogie control system program. Y25 bogie research include raw material requirements, selection criteria, comparison of domestic and international framework material, the choice of materials, performance analysis; Y25 bogie frame part theoretical analysis of spring-back control the rebound method, expand the length of the bending parts calculations, presented the mold structure, bogie Corrosion Research, coating effects, anti-corrosion coating development trend of the bogie, bogie anti-corrosion coating process design, including pre-coating technology and equipment, anti-corrosion coating selection, coating deposition process and equipment, selection of curing process; Y25 bogie thermal cutting, wheel on the pressure equipment, testing and other technical design, proposed quality control system solutions Y25 bogie.Y25 bogie completed this bending parts manufacturing related theoretical analysis, carried out by the relevant process parameters and the design of the mold has been validated in small batch production. Enrich the research projects produced and bending parts Y25 bogie bogies the content of corrosion processes and theory, have some academic value, the production of a greater role in guiding practice, in order to engage in railway freight bogie welding quality control of production and provide a useful reference.
