Claims

[Claims for Utility Model Registration] (1) A columnar mandrel mold with a circular cross section that is installed horizontally and has a ground side electrode member embedded along the top, and a semicircular shape along the outer periphery of the lower half of the mandrel mold. The middle part of a metal plate having a mold surface and a plate width equal to the outer circumference of the mandrel mold is placed and pressed against the mandrel mold, so that the middle part has a semicircular cross section and both ends of the metal plate have a semicircular cross section. A lower mold is used to form a semi-cylindrical body extending upward, and both ends of the plate material formed into the semi-cylindrical body are pressed into contact with the outer periphery of the upper half of the mandrel mold, and the plate material is molded into the mandrel mold. an upper mold for forming a cylindrical body wrapped around the outer circumference; A metal cylindrical body manufacturing apparatus comprising a welding torch for welding the abutting portion. (2) Utility model registration claim 1, in which the electrode member is provided on the top of the mandrel mold on the extension line of the abutting portion of the cylindrical body, extending a predetermined length from the front and back of the cylindrical body. An apparatus for manufacturing a metal cylinder as described in 1.
