The utility model relates to the technical field of pipe expanding machines, and discloses a full-automatic hydraulic pipe expanding machine which comprises a base and four sets of stand columns fixed to the upper surface of the base, the upper surfaces of the stand columns are fixedly connected with a containing base, six sets of containing holes are formed in the left side face of the containing base, and pushing rods are slidably inserted into the right sides of the outer surfaces of the containing holes. According to the full-automatic hydraulic pipe expander, in the process of passing through the placing base, the placing hole, the pushing rod, the pipe expanding pin and the first hydraulic cylinder, a worker can insert a pipe into the placing hole, then the first hydraulic cylinder drives the U-shaped frame and the pushing rod to move leftwards, the pushing rod pushes the pipe to move leftwards, and the pipe expanding pin expands the left end of the pipe; therefore, the placing holes can support and lim
