Abstract

PURPOSE: To form the spherical head simply and rapidly, by pressing both ends of the metallic pipe being cut into a specified length in order to expand the middle part outward.
CONSTITUTION: The metallic pipe 1 with uniform thickness made of steel, etc., is pressed from both ends by the press dies 2, 2', whose pressing face is formed flat, in order to expand the middle part outward forming the spherical head. In case that the burr is generated in this spherical head, this spherical head formed by the press die 2 is again pressed by the reforming press die 5 in which the caliber 4 of the shape coinciding with the desired finished end face is installed at round ring type in the pressing face; hereby, the end face is finished. According to this method, the manufacture of the spherical head can save the labor.
