The invention discloses a directional automatic control bending machine which structurally comprises movable clamping columns, a fixing ring, bolts, a sticking plate, wheels, a supporting box, a control plate, an alloy plate, a fixing sleeve, a supporting shaft, an inserting seat and an automatic directional bending disc. The movable clamping columns are embedded in the inserting seat, and the bottom of the fixing ring is welded to the alloy plate; and the bolts are in threaded connection with the alloy plate. The directional automatic control bending machine is structurally provided with theautomatic directional bending disc, when the directional automatic control bending machine works, steel bars penetrates through the two movable clamping columns, the fixing effect is achieved, and thesteel bars stretch into the movable clamping columns till the steel bars abut against stopping bodies; at this moment, a rotary disc starts to rotate clockwise, a center shaft is fixed to the rotarydisc, and a bearing rotates along with the rotary disc and drives one ends of the steel bars to be bent till the steel bars are bent to form the needed angles; and thus, the stretched steel bars can be directionally bent so that the steel bar bending degrees can be consistent, and the working efficiency is improved.
