Abstract
Provided is a method for internal splitting in the cross-section of the end of a metal plate or a metal rod. The method permits free-adjustment of the width and length of incision of the internal split and gives smooth and even surfaces to the cut face of the internal split for an accurate internal splitting in the cross-section of the end of a metal plate or a metal rod only at the desired position. The invention also provides a method for manufacturing a metal container and a metal pipe by that splitting method and a method for joining metal components. The present invention includes the steps of: a process to form a crevice by abutting a splitting punch or a cleaving punch on the cross-section of the end of the metal plate or the metal rod using a means for determining the width of the internal split; and a process to advance the internal splitting further by repeating the press-splitting on the crevice multiple times using a splitting punch or a cleaving punch. The invented method uses a clamping die, at least one side of which has an opening and a clamping margin to pinch both sides of the metal plate or two opposed positions on the circumference of the metal rod. Every time of each operation step, the clamping die is positioned in advance in accordance with the position of the tip of the intended internal split.
