Abstract
PURPOSE: To facilitate the extraction of the tapered thin walled can drum from the tool after finishing the forming work, by inserting the tool, provided with the straight tubular segmental die and the elastic straight tubular rubber, into the thin walled can drum, and by radially expanding this tool at the specified position.
CONSTITUTION: The cylindrical thin walled can drum 1 is inserted into the tool A till touching the upper face of the holder 4. Next, the center shaft 5 is pushed downward, the die segments 2a turn around the fulcrum 4b in a funnel shape so as to increase diameter toward the top edge 1b of the can drum 1; hereby, the can drum 1 causes a plastic deformation and is formed into a tapered thin walled can drum 1'. Next, the segmental die 2 is stopped, and the center shaft 5 is elevated while restraining the upward movement of the die 2; hereby, the die segments 2a also turn inward around the fulcrum 4b owing to the resilience of the elastic tubular rubber 3, and return to the initial position. Hereby, the tapered thin walled can drum 1' can be easily extracted from the tool A without causing friction with the tubular surface 3a.
