Numerically-controlled wire rod bending machine

The invention discloses a numerically-controlled wire rod bending machine. The wire rod bending machine comprises a rack, wherein a machine head, a machine head rotating mechanism and a feeding device are sequentially arranged on the rack from front to back; the feeding device comprises a clamping pushing mechanism and an auxiliary guide mechanism; the clamping pushing mechanism comprises a guide rail base, a lead screw, a sliding block, a feeding rod, a motor base and a motor, the guide rail base is installed on the rack, the sliding block slides on the guide rail base in the axial direction of wire rods, the lead screw is fixed on the guide rail base and in threaded connection with a lead screw nut, the lead screw nut is installed on the sliding block through a bearing, the motor base is fixedly installed on the sliding block, the motor is installed on the motor base and in transmission connection with the lead screw nut, the back end of the feeding rod is fixed on the motor base, and a wire rod locking mechanism is installed at the front end of the feeding rod. According to the technical scheme, the feeding rod and the front end of the feeding rod are used for locking and fixing the wire rods, so that feeding and bending machining of the sectional wire rods can be implemented; and the motor and the sliding block which move synchronously as well as the auxiliary supporting and guide mechanism are used, so that the mobile feeding accuracy is improved.
