The invention provides a cable bending machine with high working efficiency. The cable bending machine comprises a machine box, an operation table arranged above the machine box, a wire bending mold arranged on the operation table, a first auxiliary wheel, a second auxiliary wheel and a driving wheel, the first auxiliary wheel is driven by a first hydraulic air cylinder, the second auxiliary wheelis driven by a second hydraulic air cylinder, the driving wheel is driven by a third hydraulic air cylinder, the first hydraulic air cylinder, the second hydraulic air cylinder and the third hydraulic air cylinder are all arranged in the machine box, a first sliding groove, a second sliding groove and a third sliding groove which allow the first auxiliary wheel, the second auxiliary wheel and thedriving wheel to do reciprocating motion correspondingly are arranged on the operation table. The electric power is used for replacing manpower, so that the labor force is liberated, the labor amountof workers is reduced, compared with the manual work, the hydraulic air cylinders can be used for bending thicker and larger cable, so that the operation range is expanded, moreover, the cable bending work is standardized and procedural, then the working efficiency is improved, and the working process is accelerated.
