Abstract

A rotatory forging device, which comprises letting the pressurization end of first mold (301) opposite to the pressurization end of second mold (302), the pressurization end of second mold (302) perpendicular to its axis, meanwhile letting the axis of first mold (301) being slanted to the axis of second mold (302) such that the working object (10) is installed between the pressurization ends of the first mold (301) and the second mold (302) so that the first mold (301) and the second mold (302) rotate synchronously while moving the molds closer to each other and pressing down the working object (10) to form a wheel part (2), and the material protruded from the pressed-down area, through the up-and-down separation of the formation calender (4) installed on the interface side of molds and on the slanted row of first mold (301), forms a wheel ring (1) from the circumference of wheel part (2) in which the wheel ring (1) extends upward-and-downward; which is characterized in that: the cylindrical auxiliary mold (303) which surrounds the shaft of first mold (301) is installed coaxial to the second mold (302) and the first mold (301) and the auxiliary mold (303) are aligned in the axis direction so that the generating line of the formation calender part of the auxiliary mold (303) on the formation calender (4) side is on the same line with the generating line of formation calender part of the first mold (301) on the formation calender (4) side.
