    摘要: A rotary forging apparatus comprises a first rotary ram (3a), a cylindrical second rotary ram (3b), a third rotary ram (3c) and a shaping roller device. The first ram (3a) and the cylindrical second ram (3b) face each other and rotate about a common axis. The third ram (3c) is located in the cylindrical second ram (3b) and can rotate about an axis inclined to the common axis. The third ram (3c) presses a workpiece against the first ram (3a) and makes the disc part of a product. The shaping roller and the second ram (3b) and a side of the first ram make the rim part of the product. The outer surface of the second ram (3b) can keep a tight contact with the workpiece during the forging because of the rotational symmetry of the second ram (3b). The overall contact stabilizes the position of the workpiece and reduces any size error of the product.
