[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: an annealing furnace for wire rod production, comprising an annealing furnace body 1; in order to facilitate the feeding of heavier wire rods into the furnace, a main body bottom plate 3 is installed at the bottom of the annealing furnace body 1, a main body top plate 4 is installed at the top of the annealing furnace body 1, and an annealing furnace fan door 5 is installed on one side of the annealing furnace body 1. The annealing furnace body 1 and the annealing furnace fan door 5 cooperate to form a whole for annealing the wire rod;

[0023] In order to realize the annealing function, a main body fan door slide groove 19 is opened in the annealing furnace body 1, and the annealing furnace fan door 5 is slidably installed in the main body fan door slide groove 19. An annealing cavity 2 is opened between the main body bottom plate 3 and the main body top plate 4. A heating coil 13 is installed in the annealing cavity 2. The main body bottom plate 3 and the main body top plate 4 are both provided with fan door slots 12. The fan door slots 12 on the main body bottom plate 3 are opened on the upper surface of the main body bottom plate 3, and the fan door slots 12 on the main body top plate 4 are opened on the lower surface of the main body top plate 4. The annealing furnace fan The two ends of the door 5 are slidably installed in the fan door card slot 12, and a fan door lock column 6 is installed on one side of the annealing furnace fan door 5. A lock tongue shaft 11 is installed on one side of the annealing furnace body 1. The main body lock tongue 8 is rotatably installed on the lock tongue shaft 11. The main body lock tongue 8 is provided with a lock tongue groove 10. The lock tongue protrusion 9 is installed in the lock tongue groove 10. A lock column slot 7 is provided on the fan door lock column 6. The lock tongue protrusion 9 is installed in the lock column slot 7. The coil to be annealed is placed in the annealing cavity 2, and then the annealing furnace fan door 5 is pulled toward the main body lock tongue 8. When the annealing furnace fan door 5 moves sideways, the upper and lower ends of the annealing furnace fan door 5 slide in the fan door card slot 12. When the fan door lock column 6 on the annealing furnace fan door 5 is blocked and limited by the end face of the annealing furnace body 1, the left and right ends of the annealing furnace fan door 5 are located in the main body fan door slide groove 19, so that the annealing furnace body 1 cooperates with the annealing furnace fan door 5 to close the annealing cavity 2. The main body lock tongue 8 is rotated, and the lock tongue protrusion 9 on the main body lock tongue 8 is aligned with the lock column card slot 7 and clamped. At this time, the fan door lock column 6 is clamped in the lock tongue groove 10, and the main body lock tongue 8 is used to cooperate with the fan door The door lock column 6 limits the annealing furnace door 5 to prevent it from accidentally moving during annealing. The annealing cavity 2 can then be heated by the heating coil 13 to heat the wire. After heating, the main body lock tongue 8 is rotated to disengage the main body lock tongue 8 from the lock column slot 7, and the annealing furnace door 5 is pulled to slide toward the side away from the main body lock tongue 8. At this time, the space in the annealing cavity 2 is exposed, and workers can directly take out the wire from the side, which is convenient for workers to operate heavy wires without the need to use lifting equipment.

[0024] The working principle is as follows: the coil to be annealed is placed in the annealing cavity 2, and then the annealing furnace door 5 is pulled to move to the side of the main body lock tongue 8, and the upper and lower ends of the annealing furnace door 5 slide in the door card slot 12. When the door lock column 6 on the annealing furnace door 5 is blocked and limited by the end face of the annealing furnace body 1, the left and right ends of the annealing furnace door 5 are located in the main body door slide groove 19, so that the annealing furnace body 1 cooperates with the annealing furnace door 5 to close the annealing cavity 2, rotate the main body lock tongue 8, and align the lock tongue protrusion 9 on the main body lock tongue 8 with the lock column card slot 7 and snap it in. At this time, the door lock column 6 is stuck in the lock tongue groove 10, and the main body lock tongue 8 is used to cooperate with the door lock column 6 to limit the annealing furnace door 5 to prevent it from accidentally moving during annealing. Then the annealing cavity 2 can be heated by the heating coil 13, thereby The wire is heat-treated, and after heating is completed, the main body lock tongue 8 is rotated to disengage the main body lock tongue 8 from the lock column slot 7, and the annealing furnace door 5 is pulled to slide toward the side away from the main body lock tongue 8. At this time, the space in the annealing cavity 2 is exposed, and workers can directly take out the wire from the side, which is convenient for workers to operate heavy wires without the need to use lifting equipment. In order to enhance the sealing effect when the annealing furnace door 5 is closed, an external air pump is connected through an external air pipe 16. After closing the annealing furnace door 5, gas is injected into the connecting air pipe 15 through the air pump. The gas enters the inflatable sealing ring 14 through the connecting air pipe 15. After the inflatable sealing ring 14 expands, it deforms under the action of the extrusion force, thereby filling the gap between the inner wall of the annealing furnace body 1 and the annealing furnace door 5, thereby increasing the sealing effect.

[0025] Example 2: Figure 1-4 In order to increase the sealing of the gap, an inflatable sealing ring 14 is installed in the annealing furnace body 1, and a connecting air pipe 15 is installed on the inflatable sealing ring 14. An external air pipe 16 is installed on one side of the annealing furnace body 1, and the connecting air pipe 15 is communicated with the external air pipe 16. A sealing ring groove 17 is opened in the lock tongue groove 10, and the inflatable sealing ring 14 is installed in the sealing ring groove 17. An air pipe groove 18 is opened in the annealing furnace body 1, and the connecting air pipe 15 is installed in the air pipe groove 18. In order to enhance the sealing effect of the annealing furnace fan door 5 when closing, an external air pump is connected through the external air pipe 16. After closing the annealing furnace fan door 5, gas is injected into the connecting air pipe 15 through the air pump. The gas enters the inflatable sealing ring 14 through the connecting air pipe 15. After the inflatable sealing ring 14 expands, it deforms under the action of the extrusion force, thereby filling the gap between the inner wall of the annealing furnace body 1 and the annealing furnace fan door 5, thereby increasing the sealing effect. The other features are the same as those in Example 1.
