<p>PURPOSE:To deform a metallic can and to form simply and easily a deformed can be rolling in the can axial direction with pressing the rolling body for forming on the surface of the body part of a bottomed cylindrical metallic can. CONSTITUTION:The surface of the body part of a bottomed cylindrical metallic can 1 is subjected to a drawing by the ball 5 for forming and made in the prescribed shape by moving P in the can axial direction with pressing the rolling tool 3 that the ball 5 is arranged on the surface of the body part of the can 1. The surface of the body part is plastically deformed simply and easily without any buckling and made in the prescribed shape. It is possible to make the deformed can with the use of roller set instead of the ball 5.</p> |
