[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 4, the utility model provides a technical solution:
[0020] An annealing furnace comprises an annealing furnace body 1 and a track frame 2, wherein a heating mechanism 11 is arranged on the inner side wall of the annealing furnace body 1, the track frame 2 is arranged on the inner side of the annealing furnace body 1, and a component carrier 3 is slidably arranged on the upper surface of the track frame 2, a sealing door 31 is fixedly installed on the left end of the component carrier 3, after the component carrier 3 completely enters the annealing furnace body 1, the right surface of the sealing door 31 is in contact with the left surface of the annealing furnace body 1, a lifting and rotating device is installed on the upper surface of the annealing furnace body 1, and the lower end of the lifting and rotating device is located in the annealing furnace body 1, and a lifting and loading device 5 is rotatably installed on the upper surface of the component carrier 3;
[0021] It should be noted that the lifting driving device includes a hydraulic telescopic rod 4, which is fixedly mounted on the upper surface of the annealing furnace body 1, and a hanger 41 is fixedly mounted on the top of the hydraulic telescopic rod 4, and a long-axis motor 42 is symmetrically fixedly mounted in the hanger 41, and the lower end of the output end of the long-axis motor 42 is slidably arranged in the annealing furnace body 1, and a contact plate 43 is fixedly mounted on the lower surface of the output end of the long-axis motor 42, and the number of the lifting and loading devices 5 is two, and the lifting and loading devices 5 include a limiting shell 51, which is fixedly mounted on the upper surface of the loading vehicle 3, and a convex support 52 is rotatably mounted in the limiting shell 51, and the convex support 52 is located directly below the corresponding contact plate 43, and the lower surface of the convex support 52 is equidistantly and circumferentially embedded with load-bearing steel balls 53, and the long-axis motor 42 is a reduction motor;
[0022] When in use, the carrier 3 is moved to the left to be removed from the annealing furnace body 1, and then, Figure 2 As shown, the cylindrical steel 6 that needs heat treatment is put on the top of the convex support 52, and then the carrier 3 is completely moved into the annealing furnace body 1. At this time, the top of the cylindrical steel 6 is located below the corresponding contact plate 43. The hydraulic telescopic rod 4 is contracted to drive the hanger 41 and the long-axis motor 42 to move downward, so that the contact plate 43 is pressed against the upper surface of the cylindrical steel 6. At this time, the position of the cylindrical steel 6 is fixed and will not separate from the convex support 52. Finally, the annealing furnace body 1 is opened and the long-axis motor 42 is started to drive the cylindrical steel 6 to rotate, thereby achieving uniform heat treatment in the annealing furnace body 1. Compared with the prior art, it can achieve the effect of uniform heating of the outer surface of the cylindrical steel 6, and effectively reduce the risk of quality degradation of the steel due to local overheating or overburning.
[0023] like Figure 2 As shown, in order to make the lifting of the hanger 41 more stable, directional rods 44 are symmetrically fixedly installed on the upper surface of the annealing furnace body 1. After the hanger 41 is slidably sleeved between the two directional rods 44, the directional rods 44 can be used to limit the hanger 41 during the lifting process, thereby making its lifting more stable.
[0024] In addition, if Figure 2 As shown, in order to avoid excessive fit between the convex support 52 and the limiting shell 51 during the rotation process, thereby affecting its rotation stability, as shown in FIG. Figure 2 As shown, two annular grooves 32 are provided on the upper surface of the carrier 3. After the load-bearing steel balls 53 are rolled in the corresponding annular grooves 32, the positions of the load-bearing steel balls 53 can be limited. Thus, the load-bearing steel balls 53 are rolled in the annular grooves 32, which can ensure that the convex support 52 remains in the proper position when rotating, avoiding excessive contact with the limiting shell 51.
[0025] Specifically, the upper surface of the track frame 2 is symmetrically provided with track grooves 21, and the lower surface of the carrier 3 is symmetrically fixed with four track wheels 33, which are rollingly arranged in the corresponding track grooves 21. The carrier 3 achieves self-sliding above the track frame 2 through the cooperation between the track wheels 33 and the track grooves 21.
[0026] Specifically, a rack plate 22 is symmetrically fixedly installed in the track frame 2, and a double-output shaft motor 7 is fixedly installed on the lower surface of the carrier 3. The output ends of the double-output shaft motor 7 are both sleeved with gears 71, and the gears 71 are respectively engaged with the corresponding rack plates 22. The double-output shaft motor 7 is a forward and reverse motor. After the double-output shaft motor 7 is started, it can use the linkage effect of the gear 71 and the rack plate 22 to drive the carrier 3 to move on the track frame 2, thereby facilitating the carrier 3 to move into or out of the annealing furnace body 1 more conveniently.
