The invention provides a forming method for a liquid nitrogen inner container cylinder with a local telescopic groove. The forming method comprises the following steps that S1, cutting and blanking are conducted according to a plane unfolding appearance drawing of the cylinder to form a cylinder unfolding material; s2, the cylinder unfolded material is formed through a rolled plate, longitudinal seams are welded, and a cylinder is formed; s3, the cylinder is rolled multiple times to form n telescopic grooves, and at most one telescopic groove is formed in each time of rolling; and S4, the two end faces of the cylinder are cut, and forming of the liquid nitrogen inner container cylinder is completed. By means of the forming method, materials of the telescopic grooves of the liquid nitrogen inner container cylinder can be obtained in the axial direction, it is guaranteed that the difference between the diameter of the cylinder part between the telescopic grooves and the diameter of the two ...
