Abstract：

Vibro-rotary forging working principle and its implemental method are introduced and vibro-rotary working mechanism during plastic deformation is analyzed.On the basis of analyzing the die and workpiece system's kinematic,the analytical relationship between forging angular rate and vibration frequency is defined,the feedrate condition that the vibro-rotary forging should be satisfied is built and some technical parameters,such as distortional angular displacement along the parts circumference and distortional length in a period are calculated.The theoretical derivation shows that the vibro-rotary forging efficiency is directly proportional to the vibration frequency and feedrate and higher than that of longitudinal vibration forging.
