Pipe piece turnover device

The utility model relates to a pipe piece turnover device which comprises a base, a turnover frame rotationally connected to the base and a rotating mechanism used for driving the turnover frame to rotate, and four vertical rods and four transverse rods perpendicular to the vertical rods are arranged on the turnover frame side by side. The two vertical rods on the outermost side are respectively provided with a rotating air cylinder, and a U-shaped pressing rod connected to the two vertical rods in the middle in a bridging mode is arranged between output shafts of the two rotating air cylinders. A flexible gasket is arranged on the surface, close to the transverse rod, of the vertical rod, square timber is arranged on the surface, close to the vertical rod, of the transverse rod, and the surface, away from the transverse rod, of the square timber is arranged to be an arc-shaped outwards-protruding convex face. According to the pipe piece overturning device, the arc-shaped outwards-protruding convex face of th
