Automatic pipe expanding and forming equipment for pipes

The invention discloses automatic pipe expanding and forming equipment for pipes, which belongs to the technical field of pipe forming and comprises a worktable, and a lifting feeding device, a linear feeding device, a pushing device, a reaming device and a ring groove forming device are arranged on the worktable. The lifting feeding device ascends and descends on the outer side of the feeding end of the lifting feeding device, and the pipes are conveyed to the linear feeding device during ascending. The linear feeding device conveys the pipes to the front end of the pushing device one by one; the pushing device slides on the outer side of the discharging end of the lifting feeding device and pushes the pipe to the annular groove forming device during sliding. The reaming device slides at the front end of the annular groove forming device, and is used for reaming a pipe on the annular groove forming device during sliding; the annular groove forming device slides at the front end of the pushing device, clamps
