Claims

[Scope of utility model registration request]

The shaft rotates, the die and hammer open in the radial direction due to the centrifugal force of the shaft, the head of the hammer contacts the roller, rotates the roller case in the same direction as the shaft, and the hammer passes under the roller. In the die of a swaging machine, where an impact is applied in the radial direction each time the workpiece is pressed, and this impact is transmitted to the die and processes the workpiece as a processing force, the contact area between the workpiece and the die is 75.
~85%, and the workpiece introduction angle is 8
Swaging machine die with angles between °, 30' and 10°, 00'.
