The invention discloses a wiredrawing type high-speed electric arc spraying gun. The wiredrawing type high-speed electric arc spraying gun comprises a wire feeding motor, a speed reducing mechanism, wire feeding mechanisms and a spraying gun head, wherein an output shaft of the wire feeding motor is connected with the speed reducing mechanism; two ends of an output shaft of the speed reducing mechanism are connected with the wire feeding mechanisms respectively; wire inlet and outlet pipes are arranged on each wire feeding mechanism; the spraying gun head comprises a rear gun body; a front gun body is mounted at the front end of the rear gun body; a spray nozzle is fixed on the rear gun body through a support seat and extends out of an inner cavity of the front gun body; an airflow flow channel is formed in the rear gun body and penetrates through a converging-diverging flow channel of the spray nozzle; an outer cover is arranged on the outer wall of the spray nozzle, and an annular flow channel communicated with the converging-diverging flow channel is formed between the outer cover and the spray nozzle; the rear gun body is equipped with two current contact nozzles, the current contact nozzles correspond to corresponding wire guiding inclined holes in the spray nozzle, and two wires conveyed from the wire guiding inclined holes are converged nearby the converging-diverging flow channel. According to the wiredrawing type high-speed electric arc spraying gun, the particle spray speed can be increased, so that the atomizing jet is more uniformly concentrated, wire feeding parts in the wire feeding mechanisms are prevented from being contacted with wires and dust, and the service life is effectively prolonged.
