[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model discloses a movable tempering furnace, including a tempering furnace body 10. An arc-shaped through groove 20 penetrating to one side is opened on the front surface of the tempering furnace body 10. A heating furnace cavity 30 is opened in the arc-shaped through groove 20. A heat preservation outer shell 40 fixedly connected to its side wall is installed on the front surface of the tempering furnace body 10. A circular heat preservation box body 50 rotatably connected thereto is arranged inside the heat preservation outer shell 40. A thickened partition board 60 integrally connected to its inner wall is inlaid inside the circular heat preservation box body 50. A vacuum cavity 70 is formed between two adjacent thickened partition boards 60. A storage mechanism 80 is installed inside the circular heat preservation box body 50. A driving mechanism 90 is installed on the bottom surface of the heat preservation outer shell 40. A plurality of first openings 100 distributed circumferentially are opened on both the top surface and the bottom surface of the circular heat preservation box body 50. A plurality of second openings 110 distributed circumferentially are opened on both the inner wall and the outer wall of the circular heat preservation box body 50. A plurality of movable support feet 120 are installed at the bottom ends of the tempering furnace body 10 and the heat preservation outer shell 40.

[0022] The loading and unloading are fast, and a large amount of heat is not likely to flow out during the loading and unloading process. The heat preservation effect is good, no resource waste will be caused, and the working efficiency is also greatly improved.

[0023] Specifically, the driving mechanism 90 includes a mounting base plate 91 bolted to the bottom surface of the heat preservation housing 40. A motor is bolted to the bottom end of the mounting base plate 91. A gear 92 is provided on the top surface of the mounting base plate 91 and is in transmission connection with the motor. An annular tooth groove 93 is formed in the inner wall of the circular heat preservation box body 50. The front surface of the gear 92 is meshed and connected with the annular tooth groove 93. A third opening 94 is formed in the inner wall of the heat preservation housing 40, and the gear 92 penetrates through the third opening 94.

[0024] In this implementation scheme, by starting the motor, the gear 92 can be driven to rotate. The gear 92 is meshed and connected with the annular tooth groove 93, and the entire circular heat preservation box body 50 can be driven to rotate, so that loading and unloading can be automatically realized.

[0025] Specifically, the storage mechanism 80 includes vertical plates 81 bolted to the inner wall below the circular heat preservation box body 50. A plurality of pairs of sliding grooves 82 are formed on the top surface of each vertical plate 81. The depths of each pair of sliding grooves 82 are inconsistent. A slider 83 is slidably connected up and down between each pair of sliding grooves 82. A placing plate 84 is integrally connected between each pair of sliders 83. The placing plate 84 is located on the side away from the vertical plate 81 of the slider 83. Each placing plate 84 is the same. The placing plate 84 is of a sieve plate structure and is in a fan shape.

[0026] In this implementation scheme, multiple workpieces can be stored, so that multiple workpieces can be tempered simultaneously, with high working efficiency, and the whole replacement is convenient without being arranged in the heating furnace cavity 30.

[0027] Specifically, a plurality of first covers 130 distributed circumferentially are hinged to the top surface of the heat preservation housing 40, and the first covers 130 are aligned with the first opening 100. A plurality of second covers 140 are hinged to the outer wall of the heat preservation housing 40, and the second opening 110 is aligned with the second covers 140.

[0028] In this implementation scheme, the setting of the first cover 130 facilitates the taking out or storing of workpieces, while the setting of the second cover 140 facilitates the subsequent replacement of the storage mechanism 80.

[0029] The working principle and usage process of the present utility model: When tempering the workpiece, the heat in the heating furnace cavity 30 is not easy to dissipate. At this time, the staff can use the spare time to load and unload the workpiece (open the first cover 130, take out the workpiece that has been tempered on the placing plate 84, and put in the workpiece that has not been tempered). After the workpiece in the heating furnace cavity 30 is tempered, start the motor to rotate forward, the gear 92 rotates forward. Since the gear 92 is meshed and connected with the annular tooth groove 93, the entire circular heat preservation box body 50 rotates forward accordingly, so that the tempered workpiece is separated from the heating furnace cavity 30, and the workpiece that has not been tempered enters the heating furnace cavity 30. The arc-shaped through groove 20 is always in a sealed state, and the heat is not easy to dissipate, with high loading and unloading efficiency and high working efficiency.
