This utility model discloses a back pressure device for an all-electric bending machine, including a frame, a slider, a transmission assembly, and an anti-drop mechanism. The slider is equipped with a downward pressing blade. The transmission assembly is mounted on the frame. The anti-drop mechanism includes a vertically extending connecting rod, a connecting block mounted on the frame, and a pre-tensioning spring.
