Arc bending method of steel rail for slippage

The invention discloses an arc bending method of a steel rail for slippage. The arc bending method of the steel rail for slippage comprises a base, a feeding device, a jacking device, a bending die and a bending device, wherein the feeding device, the jacking device and the bending die are all fixedly connected to the upper side of the base, and the bending die is fixed at the output end of the feeding device through screws. The feeding device is used for guiding the steel rail into the bending die, and the jacking device is used for driving the bending device to abut against the steel rail for forming. According to the arc bending method of the steel rail for slippage, the feeding device guides the steel rail to move forwards into the preset bending die, and the jacking device can push the arc bending device to move forwards to extrude the shaped steel rail. In the process, the included angle between extrusion plates is gradually increased, and the zigzag position can be continuously changed, so that a shapi
