The invention discloses a rotating pipe shaping and pulling device and method, and relates to the field of pipe production equipment. The device comprises a pulling sleeve arranged on a rotating pipe in a sleeving manner; the two ends of the pulling sleeve are sleeved with hooping devices; a key groove is formed in the outer wall of the pulling sleeve; the key groove is fixedly connected with a rotating wheel through a key; the rotating wheel meshes with a driving wheel; one end of the driving wheel is connected with a motor through a driving shaft; the rotating wheel and the driving wheel are arranged on a transmission box body through bearings; the pulling sleeve penetrates through the rotating wheel and the transmission box body; friction blocks are evenly arranged on the inner wall of the pulling sleeve; and the friction blocks make contact with the outer wall of the rotating pipe. With the adoption of the shaping and pulling method of the rotating pipe shaping and pulling device, spiral pulling of the pipe in the axial direction is realized, and the pulling efficiency is improved.
