The pipe flaring device comprises a mounting shell (100), a transmission mechanism (200), a flaring convex ring (300) and a guide-in mechanism (400), wherein the mounting shell is provided with a flaring cavity (110) for a pipe to be inserted therein; the guide-in mechanism is located in the flaring cavity; the flaring convex ring is arranged outside the guide-in mechanism in a sleeved manner; the guide-in mechanism is connected to the transmission mechanism; the transmission mechanism is used for driving the guide-in mechanism to move in the flaring cavity; the guide-in mechanism is used for extending into the pipe; and the flaring convex ring is used for circumferentially abutting against an end opening of the pipe. According to the pipe flaring device, by using the flaring convex ring, circumferential uniform abutting against the end opening of the pipe is achieved, thereby ensuring the stress uniformity of the pipe during flaring.
