Servo-driven small-deformation radial precision forging device

A servo-driven small-deformation radial precision forging device comprises forging mechanisms and feeding mechanisms directly facing centers of the forging mechanisms, wherein each forging mechanism comprises multiple radially-arranged and servo-driven independent forging working units; the feeding mechanisms perform axial conveying and control rotating blanks, and radial flexible rotating forging is realized by the aid of the forging working units; and each forging working unit comprises a power mechanism, a primary speed reducing mechanism, a crank connecting rod mechanism, a forging head and a guiding mechanism, the power mechanism outputs rotating torque to the crank connecting rod mechanism by the aid of the primary speed reducing mechanism and converts the rotating torque into reciprocating motion, and the forging head makes contact with the guiding mechanism to realize limited precision forging. With the device, the application range of the device can be expanded while the device is flexible and intelligent, the universality of the device is improved, meanwhile, mechanisms are simplified, and the cost of the device is reduced.
