[0020] The following will further elaborate on the technical solutions of a deformed graphite ring correction device and its using method according to the present invention in combination with embodiments.

[0021] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] As Figure 1 , Figure 2 shown, a deformation graphite ring 12 correction device of this embodiment includes a fixed correction mechanism inside the furnace and a power transmission mechanism outside the furnace; the fixed correction mechanism inside the furnace includes a fixed plate 1 installed and fixed inside the high-temperature furnace, a column 2 is rotatably connected to the fixed plate 1, an inner correction ring 3 is detachably connected to the column 2, a vertical rod 4 is slidably connected to the fixed plate 1 corresponding to multiple radial extension lines of the inner correction ring 3, and an outer flap 5 is detachably connected to the side of the vertical rod 4 facing the inner correction ring 3; the external power transmission mechanism includes a first power device for driving the column 2 to rotate and a second power device for driving the vertical rod 4 to move on the fixed plate 1. Among them, the vertical rod 4 and the fixed plate 1 can adopt any sliding connection method as long as it can be driven to move by the second power device. The inner side surface of the outer flap 5 is set to match the arc of the outer wall of the graphite ring 12, and the outer wall diameters of different graphite rings 12 are different, so the arc of the inner side surface of the outer flap 5 is different. Each component in this application is made of high-temperature resistant materials that can withstand the working temperature inside the high-temperature furnace. When in use, the graphite ring 12 is fixed on the inner correction ring 3, the first power device drives the column 2 to rotate, and the second power device drives the vertical rod 4 to move along the radial extension line of the column 2 towards the column 2, so that the outer flap 5 corrects the graphite ring 12. With the structure of this application, the graphite ring 12 can be better corrected inside the high-temperature furnace, so that the graphite ring 12 can ensure product quality and service life.

[0023] Further, the first power device includes an inner guide rod 6 rotatably connected to the high-temperature furnace, the inner end of the inner guide rod 6 is detachably connected to the column 2, the outer end extends outside the furnace and is installed with a first connection head 7, and is connected to the output end of a first motor through the second connection head 10. After the fixed plate 1 is installed inside the high-temperature furnace, the column 2 is connected to the inner guide rod 6 and driven to rotate by the first motor, so that the graphite ring 12 rotates inside the high-temperature furnace and cooperates with the outer flap 5 for uniform correction.

[0024] Further, the second power device includes an upright frame 8 installed inside the high-temperature furnace body, a threaded column 9 rotatably connected to the upright frame 8. The outer end of the threaded column 9 penetrates through the high-temperature furnace and is equipped with a second connector 10, and is connected to the output end of a second motor through the second connector 10. A rotating seat 11 is threadedly connected to the threaded column 9, and the upper end of the rotating seat 11 is detachably connected to the upright rod 4. A limiting member for preventing the rotating seat 11 from rotating along with the threaded column 9 is provided on the rotating seat 11, or it is limited by the upright rod 4 after being detachably connected to the upright rod 4. A sliding cavity for the movement of the upright rod 4 is provided on the fixing plate 1. The lower end of the upright rod 4 penetrates through the sliding cavity and is detachably connected to the fixed seat. The upright column 2 can adopt any sliding connection method and is installed on the fixing plate 1 or inside the sliding cavity. The second motor drives the threaded column 9 to rotate on the upright frame 8, so that the rotating seat 11 displaces on the threaded rod, thereby driving the upright rod 4 to slide, so that the outer flap block 5 presses the graphite ring 12 in a high-temperature environment to correct it.

[0025] Further, a square plug is provided at the upper end of the inner guide rod 6, and a jack for mating with the square plug is provided on the upright column 2. A fixing hole for mating with the lower end of the upright rod 4 to be inserted is provided on the rotating seat 11. By adopting the method of mating the square plug with the jack and the upright rod 4 with the fixing hole, the connection structure is simple and the disassembly and assembly are convenient.

[0026] Further, it includes four upright rods 4, and the four upright rods 4 are distributed on the fixing plate 1 at intervals of 90° along the circumferential direction of the upright column 2.

[0027] A method for using a deformed graphite ring correction device includes the following steps:

[0028] Step A: Select an inner correction ring corresponding to the minimum inner diameter of the graphite ring and detachably connect it to the upright column.

[0029] Step B: Select an outer flap block corresponding to the maximum outer diameter of the graphite ring and detachably connect it to the upright rod.

[0030] Step C: Install the graphite ring on the inner correction ring and send the entire fixed correction mechanism inside the furnace into the high-temperature furnace, so that the fixed correction mechanism inside the furnace is linked with the power transmission mechanism outside the furnace.

[0031] Step D: Drive the upright column to rotate through the first power device, thereby driving the graphite ring inside the high-temperature furnace to rotate, and drive the upright rod to move towards the direction of the upright column through the second power device, so as to correct the graphite ring by using the outer flap block in cooperation with the inner correction ring.

[0032] Step E: After reaching the preset time threshold, repeat steps A-D until the graphite ring is completely corrected.

[0033] With this solution, an inner correction ring that matches the minimum diameter of the inner wall of the graphite ring can be used at the time when the circumferential ring of the graphite ring is most severe, which can ensure the installation of the graphite ring; and an outer lobe block that matches the maximum diameter of its outer wall can be used to prevent damage to the graphite ring caused by improper diameter matching; and the graphite ring and the overall in-furnace fixed correction mechanism are installed in the high-temperature furnace, and the high-temperature treatment and correction of the graphite ring are carried out through the high temperature of the high-temperature furnace in cooperation with the external power transmission mechanism; at the same time, the inner correction ring and the outer lobe block need to be continuously replaced during the correction process to cooperate with the continuously changing graphite ring until the graphite ring is corrected.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
