As Figures 1-5 shown, an induction furnace temperature compensation device is installed outside the furnace body 1 to compensate the temperature of the workpiece in the furnace body 1. Among them, both the first temperature compensation component and the second temperature compensation component are installed on the outer wall of the furnace body 1. The first temperature compensation component is rotationally connected to the furnace body 1, and at least three groups of the second temperature compensation components are evenly arranged relative to the furnace body 1 and are movably connected to the outer wall of the furnace body 1, so as to adjust the angle of the second temperature compensation component relative to the outer wall of the furnace body 1 through the adjustment mechanism, so that the angle between the second temperature compensation component and the furnace body 1 can be adjusted according to the workpiece placed inside; at the same time, during the rotation of the first temperature compensation component relative to the outer wall of the furnace body 1, the internal workpiece is evenly heated. On the basis of the temperature compensation of the first temperature compensation component, further temperature compensation is carried out through the second temperature compensation component to meet the temperature compensation requirements.

[0031] In some implementation modes, the first temperature compensation component includes: a sleeve 2, the sleeve 2 is sleeved on the outer wall of the furnace body 1 and is rotationally connected to the furnace body 1.

As Figures 1-5 shown, the first temperature compensation component includes a sleeve 2. The sleeve 2 is arranged on the outer wall of the furnace body 1 in a shape adapted to the furnace body 1 and is rotationally connected to the furnace body 1. A first cavity is arranged in the sleeve 2. By filling a heating liquid into it, the heating liquid is commercially available, and then the heating liquid is heated by the first heating coil in the first cavity, so that it transfers heat to the furnace body 1. Among them, the liquid injection port and the liquid discharge port on the sleeve 2 facilitate adding and discharging the heating liquid.

[0032] In some embodiments, the second temperature supplementing component includes: a heating cylinder 3, a second cavity is respectively arranged inside the heating cylinder 3, and a second heating coil is arranged inside the second cavity. As Figures 1-5 shown, the second temperature supplementing component includes: a heating cylinder 3, at least three groups of heating cylinders 3 are evenly arranged around the furnace body 1 as the center, a second cavity is arranged inside the heating cylinder 3, air is filled inside the second cavity, and the air inside the second cavity is heated by the second heating coil. The second heating coil is commercially available. After adjusting the angle of the heating cylinder 3 relative to the furnace body 1, heat transfer is carried out on the workpiece inside the furnace body 1. When facing a special-shaped workpiece or when the partial heating temperature of the workpiece needs to be regulated, after adjusting the angle, the relative distance is changed, so as to achieve the function of adjustable temperature.

[0033] In some embodiments, a rotating part 4 is arranged at one end of the heating cylinder 3, and rotating seats 5 adapted to the rotating part 4 are respectively arranged on the outer wall of the furnace body 1. The second cavity is rotationally connected to the rotating seat 5 through the rotating part 4. As Figures 1-5 shown, the heating cylinder 3 is rotationally connected through the arranged rotating part 4 and the rotating seat 5. The connection between the rotating part 4 and the rotating seat 5 can be through a rotating shaft, so as to facilitate the adjustment of the angle of the heating cylinder 3.

[0034] In some embodiments, the adjusting mechanism includes a rotating ring 6. The rotating ring 6 is arranged below the sleeve 2. The inner side of the rotating ring 6 is rotationally connected to the outer side of the furnace body 1. Extension edges 7 corresponding to the heating cylinder 3 are evenly arranged outside the rotating ring 6 with the furnace body 1 as the center. Arc-shaped sliding holes 8 are respectively arranged on the extension edges 7. Sliding grooves 9 are correspondingly arranged on the outer wall of the furnace body 1 below the extension edges 7. Sliding bars 10 are respectively arranged inside the sliding grooves 9. The sliding bars 10 are respectively slidably connected to the sliding grooves 9. A sliding rod 17 is arranged on the side of the sliding bar 10 close to the extension edge 7. The sliding rod 17 is slidably connected to the arc-shaped sliding hole 8;

[0035] First supports 11 and second supports 12 are respectively arranged on the mutually approaching surfaces of the correspondingly arranged heating cylinder 3 and the sliding bar 10. The first supports 11 and the second supports 12 are respectively close to the edges of the ends of the heating cylinder 3 and the sliding bar 10 away from the furnace body 1. During the rotation of the rotating ring 6, there is a gap between the second support and the extension edge 7. Linking rods 13 are respectively arranged between the correspondingly arranged first support and the second support. The two ends of the linking rod 13 are respectively rotationally connected to the first support and the second support. As Figures 1-5As shown, the rotating ring 6 of the adjusting mechanism is arranged below the sleeve 2. The rotating ring 6 is rotatably connected to the furnace body 1. When the rotating ring 6 rotates relative to the furnace body 1, due to the cooperation of the sliding rod 17 and the arc-shaped sliding hole 8, a plurality of sliding rods 17 respectively travel along the direction of the arc-shaped sliding hole 8. And the sliding rods 17 are arranged on the slide bar, driving the slide bar 10 to slide in the sliding groove 9. Furthermore, when both ends of the linkage rod 13 are rotatably connected to the first support 11 of the heating cylinder 3 and the second support 12 on the slide bar 10, when the slide bar 10 slides, it drives the linkage rod 13 to form a triangular linkage, driving the angle of the heating cylinder 3 relative to the furnace body 1 to change. Due to the setting of the extension edge 7, the plurality of heating cylinders 3 are driven to form a linkage; at the same time, during the rotation of the rotating ring 6, both the second support and the extension edge 7 are arranged with a gap, so that it does not prevent the rotation of the extension edge 7.

[0036] In some embodiments, the shape of the arc-shaped sliding hole 8 is the same as that of the extension edge 7, both being an arc-shaped structure from the end close to the rotating ring 6 to the end far from the rotating ring 6. As Figures 1-5 shown, the arc-shaped sliding hole 8 is an arc-shaped path structure, which can make the rotation angle control of the rotating ring 6 during the linkage process more accurate, and further make the angle adjustment of the heating cylinder 3 more precise.

[0037] In some embodiments, a limiting block 14 is respectively arranged at the end of the sliding rod 17 far from the slide bar 10, and the limiting blocks 14 are respectively slidably connected to the extension edge 7. As Figures 1-5 shown, a limiting block 14 is arranged at the end of the sliding rod 17 far from the slide bar 10. When the limiting block 14 is slidably connected to the extension edge 7, it prevents the sliding rod 17 from disengaging, increasing the stability of its transmission.

[0038] In some embodiments, a gear ring 15 is arranged at the bottom of the rotating ring 6. A gear is externally meshed with the gear ring 15. An electric motor 16 is arranged on the outer wall of the furnace body 1 below the gear, and the output shaft of the electric motor 16 is connected to the gear. As Figures 1-5 shown, the electric motor 16 is commercially available. The gear is driven by the forward and reverse rotation of the electric motor 16. Among them, the connection between the output shaft of the electric motor 16 and the gear can be through a coupling to connect a rotating rod, and the rotating rod is then connected to the gear. The gear drives the gear ring 15, thereby driving the rotating ring 6 to rotate relative to the furnace body 1.

[0039] In some embodiments, the sleeve 2 is arranged on the rotating ring 6, and the inner side of the sleeve 2 is rotatably connected to the outer wall of the furnace body 1. As Figures 1-5 shown, after the sleeve 2 and the rotating ring 6 are connected, the rotation of the rotating ring 6 drives the sleeve 2 to rotate relative to the furnace body 1 during the rotation process, thereby making it heat evenly.
