ABSTRACT:
The hot working method using a swaging machine provides for the minimizing heat transfer by the heat conduction from the preheated dies and work through the surrounding mechanical power transmission parts during the swaging process for the workpiece. The swaging machine has a die section including pairs of die elements and curved-profile buckers, the die elements having the working ends exposed toward the center beyond the inner sides of the corresponding buckers and the die elements and buckers being held together by means of steel balls, the motor-driven sectorial spindles for driving the die working section for rotation, the spindles and buckers being held together by means of steel balls, and springs for biasing the die working section toward the outside.
