The production process of high-speed rail cabin 1 plus X
The production of high-speed rail cabin 1 plus X is roughly divided into 4 processes, namely:
(1) Making the body floor and keel frame
The body size of the high-speed rail cabin 1 plus X is 1:1, the front and the front are divided into 2 sections, and the actual length after manufacture is 17 meters. The main body of the body is made of 3030mm square steel, which has been cut, welded and polished. The parts are connected with bolts to avoid mistakes.
②The skin is laid on the outside of the body
The outer skin of the high-speed rail cabin 1 plus X is welded and fixed on the frame with a 1.5mm sheet. The material is laser-cut to ensure accurate dimensions and numbered according to the position of the body. After completion, it is assembled and welded in the order of numbering. The special-shaped surfaces such as the arc unfolded surface are rolled and formed by a bending machine, and polished after the overall welding is completed.
③Brush fiber putty powder, sand and paint
The spraying process of the high-speed rail cabin 1 plus X adopts spray paint and imported metallic paint. In the early stage, it is sprayed after several times of grinding. In order to ensure the strength of the paint, the fiber putty is scraped in the early stage. After drying and grinding, the surface is adjusted by brushing the surface dust and spraying primer. Finish. After the finishing of the spraying of the high-speed rail cabin 1 plus X, the water grinding process is used to polish the parts on the body that need to be sprayed in detail, and then spray the primer with topcoat for surface finish treatment.
④ Body interior installation
In the early stage of high-speed rail cabin 1 plus X, the driver's driving console at the front of the locomotive was strengthened. In order to ensure the similarity between the processing accuracy of the driving platform and the real object, 3D printing was used, and after polishing, it was polished and colored. The display and operation buttons are made from the actual train. The same parts are made to realize the restoration of the high-speed rail cabin 1 plus X.
