A torsion shaft structure based multi-link all-electric servo synchronous bending machine, comprising a machine frame (1), a lower die (2) fixedly connected to the machine frame and used for bending, a slider (3) capable of moving up and down along the machine frame, and an upper die (4) fixedly connected to the slider and cooperating with the lower die to perform bending, wherein the slider (3) is left-right symmetrically connected to two drive mechanisms for driving the slider to realize a nonlinear motion characteristic.
