<p>PROBLEM TO BE SOLVED: To provide a swaging device which is capable of increasing the punch quantity of a die to realize the high working speed without increasing the size of a whole device or complicating its structure, and capable of simply interlocking the punch by the die with the release only by the positional relationship between a roll and the die. SOLUTION: In a swaging device 20 to bring dies 1, 2 into contact with a roll and to make the dies move to the center by rotating a shaft 10, or a roll 8 and a roll cage 9, a plurality of dies in which the effective punching area of the dies to a work is smaller than the effective contact area of the dies to the roll are arranged across each other on a die arrangement part, and a plurality of punching parts by the dies are provided.</p> |
