The utility model discloses a
copper wire annealing device for cable production. The
copper wire annealing device comprises a furnace body, a heating
pipe, a heat insulation cylinder and a limiting
assembly, the furnace body is provided with a heat insulation cylinder, a
refractory brick is arranged in the heat insulation cylinder, a heating
pipe is transversely arranged in the
refractory brick, sleeves are arranged at the two ends of the heating
pipe, and the sleeves are fixed in the
refractory brick through refractory glue; the refractory bricks and the heat insulation cylinder arranged on the device can isolate high temperature generated by the heating pipe, heat is prevented from baking the furnace body, a
copper wire enters the device from the left side, it can be guaranteed that the
copper wire is always kept horizontal from the second limiting wheel to the cylinder, the whole
copper wire is straightened, the
copper wire is prevented from making contact with the heating pipe, all-around annealing of the copper wire is guaranteed, and the service life of the copper wire is prolonged. The device is simple in structure, the copper wire production efficiency can be greatly improved, the investment of labor cost is reduced, and automatic annealing is realized.
