This utility model relates to the field of urban rail vehicle component processing technology, and discloses a bending and forming device for aluminum alloy parts of urban rail vehicles. The device includes a frame, a material support platform fixedly mounted on the upper end of the frame, a downward hydraulic rod fixedly mounted on the upper end of the frame, and a downward pressure plate fixedly connected to the lower end of the hydraulic rod. A rotating bending hydraulic rod is mounted on the lower end of the frame, and a bending plate is rotatably connected to the upper end of the hydraulic rod. A switching mechanism is provided inside the downward pressure plate, which changes the concave shape of the material by switching the shape of the contact point with the material. This bending and forming device for aluminum alloy parts of urban rail vehicles, by setting a switching mechanism inside the downward pressure plate and using a switching motor to drive the central shaft to rotate, can easily switch the contact between the arc-shaped contact rod and the right-angle contact rod with the material, thereby changing the concave shape of the material. Compared with traditional devices, this eliminates the need to replace the entire contact component or even the mold.
