Modeling process and structural repair of a railway or metal car

A process of structural repair and coating of a metal car, which facilitates maintenance operations, reduces the accumulation of remaining material (carryback) and decreases the weight of said metal car, wherein it includes the stages of:

• i. Provide the metal car to be repaired, which includes:
• a mobile base platform that has a supporting structure mounted, which, in turn, has a hopper made of steel plates mounted, wherein said supporting structure is formed by pokers and beams;
• ii. scan the metal car to obtain a 3D plan of the dimensions and arrangement of elements;
• iii. model and calculate the geometry of a new hopper from the scan of the metal car;
• iv. remove the steel hopper from the metal car;
• v. repair and adapt the supporting structure for the assembly of the new hopper;
• vi. manufacture a plurality of structural elements that form the new hopper;
• vii. join the structural elements so that the new hopper comprises a self-supporting body in one piece that includes corners or curved segments to prevent material accumulation and two openings in its bottom;
• viii. install gates in the bottom openings of the new hopper;
• ix. mounting a drive mechanism on each gate to open and close said gates;
• x. Mount the new hopper on the supporting structure of the metal car.
