Description
Technical Field
The utility model belongs to rail car body member field especially involves a side post for rail vehicle.
Background
Rail transit is a fast and relatively low-cost traffic mode all the time, and along with the development of science and technology, the components of rail vehicles are changed continuously, and the performance requirements are gradually improved.
The defects of foaming, scabbing, folding, slag inclusion, section layering and the like cannot exist on the surface of a rail vehicle part due to actual needs, meanwhile, scratches and indentations cannot be formed, and stains cannot exist on the surface to keep consistent color and luster; the edge of the part cannot have the defects of flash, burr and the like, otherwise, the very serious potential safety hazard can be generated in the work process. Meanwhile, as the parts of the rail vehicle need to work for a long time, the surface needs to have certain capacity of resisting acid-alkali corrosion.
The rail vehicle cold-bending side column is one of rail vehicle components, is used for supporting two sides of a boxcar, is very large in usage amount, is easy to deform due to loading, is short in replacement and maintenance period, influences the use of the boxcar of the rail vehicle, and increases operation cost.
Therefore, there is a need in the art for a new solution to solve these problems.

The utility model discloses the technical problem that will solve is: the cold-bending side column of the railway vehicle is provided, the strength of a vehicle body is improved, the safety of the railway vehicle is improved, and the use cost of the vehicle is reduced.
A rail vehicle cold-bending side column is characterized in that: comprises a side column;
the side columns are of an axisymmetric structure and formed by cold bending of a steel plate with the thickness of 7mm, wherein the side columns are provided with a support plate I and a support reinforcing part;
support reinforcing parts are arranged at two ends of the support plate I and comprise a support plate II, a reinforcing plate I, a reinforcing plate II and a reinforcing plate III;
the supporting plate II, the reinforcing plate I, the reinforcing plate II and the reinforcing plate III are connected in sequence, and the supporting plate II, the reinforcing plate I, the reinforcing plate II and the reinforcing plate III are connected through arcs;
wherein the arc radius of the arc is 10 mm;
the length of the support plate II is 63 mm;
the supporting plate I, the supporting plate II and the reinforcing plate II are parallel to each other;
the included angle between the support plate II and the reinforcing plate I is 70.4 degrees;
the included angle between the reinforcing plate II and the reinforcing plate III is 84.7 degrees.
The distance between the supporting plate II and the plane of the reinforcing plate II is 52 mm.
