Abstract: A device for forming a V-shaped full-composite pressure vessel includes a semi-cylinder body mold, where the length of a cylinder body part of the semi-cylinder body mold is half of the length of a cylinder body of a processed pressure vessel; a groove for placing a valve seat is reserved at one end of a dome part of the semi-cylinder body mold, and a fiber yarn-dividing ring is mounted at the other end; the semi-cylinder body mold is connected to the valve seat through a spline; and the valve seat and the fiber yarn-dividing ring are in threaded connection with a rotating shaft of fiber winding equipment. According to this disclosure, a liner-free pressure vessel can be manufactured completely by processing a composite material, so the mass of the pressure vessel can be reduced. Furthermore, the mold is not required to be dissolved and taken out.
