Background
Rotary forging is a method in which a rotating die is used to apply a high frequency radial force to a billet such as a bar, a wire, a pipe, etc., and the billet is radially compressed to be shaped according to the profile of the die. It is a local and continuous, chipless and precise metal forming process.
The part adopting rotary forging not only has continuous fiber streamline, but also can improve the strength thereof through work hardening, and simultaneously can change a solid structure into a hollow structure so as to achieve the purpose of reducing weight and material. At present, feeding in rotary forging is basically carried out at a constant speed by adopting mechanical and hydraulic clamping, because a blank is also fed in a descending process of a die, the frequency of difficulty in feeding the blank into the die is relatively high due to the blocking of a bell-mouth-shaped rotary forging die, and particularly when the blank or hot rotary forging with low strength is carried out, part of materials flow in the reverse feeding direction and the reverse flow is larger than the forward flow, so that the feeding force and the forging force are increased, and the service life of the tool is shortened. This phenomenon is more prominent at higher feed rates and therefore also affects molding efficiency.
