Feeding device for numerical-control wire bending machine

The invention discloses a feeding device for a numerical-control wire bending machine. The feeding device comprises a clamping pushing mechanism and an auxiliary guide mechanism, wherein 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 a machine frame, the sliding block axially slides along a wire rod on the guide rail base, the lead screw is fixed on the guide rail base, a lead screw nut is in threaded connection on the lead screw, 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, the motor is in transmission connection with the lead screw nut, the rear 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 material feeding rod and the wire rod which is fixedly locked at the front end of the material feeding rod are adopted to enable feeding of the segmented wire rod and wire bending machining to be implemented, synchronous movement of the motor and the sliding block is adopted, ancillary shoring is carried out on a guide mechanism, and the moving feeding precision is improved.
