Problems solved by technology
This solution has almost no cost increase. However, since the end wall of the urban rail car is a welded structure, the production process has to go through 6 assembly welding processes such as part opening and small part welding. Each process has different degrees of welding deformation, resulting in The dimensional accuracy of the final opening position cannot be guaranteed, nor can the concentricity accuracy between the openings of each component be guaranteed
Therefore, this scheme is not suitable for the manufacturing process of rail vehicle body mainly in manual welding.

Description
Technical field [0001] The invention belongs to the technical field of rail vehicles, and particularly relates to a tooling and process for perforating the end wall of a stainless steel urban rail car body. Background technique [0002] During the processing of rail vehicles, the pedal ladder structure is usually bolted in carbon steel rail vehicles. The pedal ladder is connected by arc welding. The inner side of the wall is a fillet weld, and the side of the wall is a butt weld. There are 14 pedaling ladders in each end wall with pedaling ladders, with 28 holes in total, and extremely high requirements for the diameter and relative position of the round holes; in order to ensure the connection strength, increase the structural rigidity, and reduce the deformation of the wall panel, the Add 4mm reinforcing plate to the inner side of the wall at the hole position; [0003] There are two schemes for designing process schemes based on existing technology: [0004] 1. The hole-opening ...
