Copper conductor DC annealing device

A copper conductor DC annealing device disclosed by the utility model is characterized by comprising a belt pulley, a wheel shaft, a contact wheel, a conductive wheel and a conductive belt, wherein the belt pulley and the contact wheel are both arranged on the wheel shaft, and the conductive wheel sleeves on the contact wheel; a circle of conductive belt is arranged on the outer surface of the conductive wheel, the two ends of the wheel shaft are compressed by compressing covers, and a space ring and an insulating sleeve are arranged at the side edge of the contact wheel orderly. According to the utility model, the belt pulley drives the contact wheel and the conductive wheel to operate, so that the function of drawing while annealing is realized directly, the operation processes are reduced, and the labor cost is reduced substantially. The conductive belt is added on the conductive wheel, so that on one hand the influences of electric sparks generated by the friction of a copper conductor and the conductive wheel, etc., are reduced, on the other hand, the wear resistance of the conductive wheel can be increased.
