Abstract
PURPOSE: To mold the necking without causing wrinkles, etc., by reducing the inside of the lower end part of the die-ring two times, and making it a regular taper angle by means of plastic working.
CONSTITUTION: The can barrel end 3 is intruded along the inside guide face of the guide ring 4 by lowering the metallic mold 2, and the lowering center ring 10 is inserted into the can barrel end 3. The can barrel end 3 is guided to the reducing face of the die-ring 7 by lowering the die-ring 7, and the shoulder part having a taper angle of 20W30° is molded. Furthermore, by lowering the center ring 10 and the die-ring 7, the can barrel end is pressed into the circumferential space 14 of the die-ring 7 and is reduced, and the half-molded neck part connected to the shoulder part 13 is plastically worked. After that, the neck part connected to the shoulder part 13 of the can barrel 1 is reduced continuously by use of the molding die metallic mold 20 having the same structure as the foregoing. by carrying out the afore- mentioned method, the molding workability of necking is elevated.
