Bending machine

The utility model relates to a bending machine, in particular to a bending machine suitable for machining and forming aluminum alloy sections with specific sections in high-speed rails, and aims to solve the problems that the existing bending machine cannot be used for machining and forming the aluminum alloy sections with special-shaped sections and cannot be used for large-radian bending of long sections. The forming machine comprises a frame body, a plurality of pushing head forming devices, a plurality of limiting forming devices and a hydraulic system, the pushing head forming devices and the limiting forming devices are installed on the frame body side by side in the length direction of the frame body, one limiting forming device is installed between every two adjacent pushing head forming devices, and the hydraulic system is installed on the frame body. An output end of the hydraulic system is connected with a hydraulic cylinder of each push head forming device, the hydraulic system provides power for
