Claims

[Scope of utility model registration request]

A drive-side punch that plunges into the container to be formed, a bottom punch that cooperates with this punch to shape the bottom center of the container inwardly into a dome shape, and a bottom punch located around the bottom punch. , and a wrinkle presser that cooperates with the corbel to shape the bottom peripheral edge of the container into an arc shape, and the bottom punch itself or the gap between the bottom punch and the wrinkle presser is used to press the container, the bottom. A mold for processing the bottom of a pressure vessel, which is formed with a punch and a wrinkle presser to form an air vent hole for removing air remaining in the chamber.
