The spiral fan blades 33 structure is used to drive the metal wire to be spirally fed and moved, which can make full use of the annealing space and improve the continuity and stability during annealing. The front surface of the wire feeding furnace 3 is provided with a wire inlet 31 on the side away from the cooling furnace 2, and the wire feeding furnace 3 is provided with a wire outlet 32 on the side close to the cooling furnace 2. The metal wire that needs to be annealed is fed into the annealing cavity 37 from the wire inlet 31 for temperature treatment. Wire holes 27 are provided on both sides of the cooling furnace 2, and the annealing cavity 37 and the cooling cavity 25 are connected to each other through the wire outlet 32 and the wire hole 27. Therefore, the metal wire after uniform heating leaves the annealing cavity 37 from the wire hole 27 and enters the cooling cavity 25 through the wire hole 27.

[0031] A controller 5 is provided at the top of the front surface of the cooling furnace 2, and a central processing unit 6 is provided inside the top of the cooling furnace 2. The controller 5 is electrically connected to a servo motor 2 35 through the central processing unit 6, which is used to facilitate the operator to externally control the equipment to perform annealing management of the metal wire. The top of the cooling furnace 2 is connected to the top through a fixed ventilation pipe 21, and a heat dissipation fan 22 is provided inside the ventilation pipe 21, and the central processing unit 6 is electrically connected to the heat dissipation fan 22. A partition plate 23 is fixed laterally on the inside of the cooling cavity 25, and a plurality of ventilation holes 24 are evenly distributed on the partition plate 23. A plurality of ventilation holes 28 are also provided on the front side of the cooling cavity 25, and the ventilation holes The second ventilation hole 28 and the wire-through hole 27 are both arranged on the lower side of the partition plate 23.

The servo motor 2 35 drives the connecting shaft 34 to drive the spiral fan blade 33 to rotate, and then the metal wire end is fed into the cooling furnace 2 through the wire outlet 32 for temperature treatment. Since the hot air inside the heating cavity 15 of the heating furnace 1 is connected to the annealing cavity 37 through the air supply pipe 4 on both sides of the annealing cavity 37, the circulation fan 13 is controlled to rotate by the servo motor 14. The air circulation between the heating cavity 15 and the annealing cavity 37 can be completed, and the temperature distribution in the furnace can be uniform.
