Production of high-speed rail cabins
The production of high-speed rail cabins is roughly divided into 4 processes, namely:
(1) Making the body floor and keel frame
The body size of the high-speed rail cabin 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. After the welding is completed, the body and the head are bolted. connection to avoid errors.
②The skin is laid on the outside of the body
The outer skin of the high-speed rail cabin is welded and fixed on the frame with a 1.5mm thin plate. 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 arc of the body is unfolded The special-shaped surface is 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 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 finish is adjusted by brushing the surface dust and spraying primer. High-speed rail The last process of the spraying of the cabin is to polish the parts on the body that need to be sprayed in detail with the water grinding process, and then spray the primer with the topcoat for surface finish treatment.
④ Body interior installation
In the early stage of the high-speed rail cabin, 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 of the same parts as the actual train. made, so as to achieve the restoration of high-speed rail cabins.
