Claims

[Scope of Claim for Utility Model Registration] (1) An inner core mold consisting of a cylindrical core mold with a chipped circumferential cylindrical surface having an intrusion corresponding to an inner overlapped side seam, and a drawing mold with an inner peripheral surface shaped like an inner periphery. A device for forming the neck of a metal cylindrical body with overlapping side seams. (2) Metal having an outer overlapped side seam consisting of a drawing die with a chipped circumferential inner surface having an intrusion corresponding to the outer overlap side seam on the inner circumferential surface, and a cylindrical core die with a circumferential columnar shape on the circumference. A device for forming the neck part of a cylindrical body. (3) A cylindrical core mold with a chipped circumferential cylindrical surface having a recess corresponding to the inner overhang of the overlapping side seam with inner and outer overhangs, and an inner peripheral surface with the recess corresponding to the outer overhang of the overhang side seam with inner and outer overhangs. A device for forming a neck portion of a metal cylindrical body having an inner and outer overhanging overlapping side seam, comprising a drawing die having a notched circumferential inner surface. (4) A cylindrical core mold with a chipped circumferential cylindrical surface having an intrusion equivalent to an inner lap side seam on the circumferential surface of the neck molding part and the shoulder molding part following this neck molding part, the inner surface of the neck molding, and the neck molding. A device for forming a neck portion of a metal cylindrical body, comprising a drawing die whose inner surface has a circumferential surface shape. (5) a drawing mold with a notched circumferential inner surface having an intrusion equivalent to an outer overlapped side seam on the inner surface of the neck molding and the inner surface of the shoulder molding following the inner surface of the neck molding;
A device for forming a neck part of a metal cylindrical body, comprising a neck forming part and a columnar core mold in which the peripheral surface of a shoulder forming part following the neck forming part is a circumferential columnar surface. (6) A cylindrical core mold with a chipped circumferential cylindrical surface having an intrusion corresponding to the inner overhang of the overlapping side seam with inner and outer overhangs on the peripheral surface of the neck molding part and the shoulder molding part following the neck molding part, and the neck molding part. A device for forming a neck portion of a metal cylindrical body, comprising a forming inner surface and a drawing die having a notched circumferential inner surface having a recess corresponding to the outer protrusion of the inner and outer overhanging overlapping side seams on the shoulder forming inner surface following the neck forming inner surface.
