[0002] Graphite packing rings, also known as flexible graphite packing rings, are made of flexible graphite tapes or flexible graphite braided packings by molding into rings of different sizes. Graphite packing rings are pressed from graphite tapes without any fillers or adhesives. The purity is greater than 98%. It has good resilience, chemical stability, corrosion resistance, high temperature resistance, and high pressure resistance. Its cross-section is usually square, and can also be processed into a wedge or V shape to adapt to high-pressure parts.

[0028] The effect achieved by the entire embodiment 2 is that when the device is used normally, first, the motor 205 is connected to the rotating shaft 206, the rotating shaft 206 is connected to the polishing disc 207, and the hydraulic cylinder 203 is connected to the motor 205 through the piston rod 204. The operation of the motor 205 drives the rotating shaft 206 to rotate, so that the polishing disc 207 rotates. At the same time, the operation of the hydraulic cylinder 203 drives the piston rod 204 to extend and retract to adjust the height of the polishing disc 207. By adjusting the height of the polishing disc 207, the pressure of the polishing disc 207 on the graphite packing ring can be controlled. Appropriate pressure can extend the service life of the polishing disc 207 and reduce production costs.

[0029] Among them, the damper 104, the hydraulic cylinder 1 106, the motor 1 112, the hydraulic cylinder 2 203 and the motor 2 205 are all prior art, and their components and operating principles are all public technologies, which will not be explained in detail here.

[0030] Working principle: First, when the device is used normally, the graphite ring body 116 is placed on the workbench 105. A hydraulic cylinder 106 is fixedly installed on the top of the workbench 105. A piston rod 107 is arranged at the output end of the hydraulic cylinder 106. The piston rod 107 is fixedly connected to the push plate 108. Secondly, the operation of the hydraulic cylinder 106 drives the piston rod 107 to extend and retract, thereby driving the push plate 108 to move to push the position of the graphite ring body 116. When the hydraulic cylinder 106 pushes the graphite ring body 116 for processing, the thrust and speed can be adjusted as needed to adapt to different polishing requirements and Processing efficiency can achieve efficient processing and improve production efficiency while ensuring quality. Secondly, the graphite ring body 116 stays on the storage plate 115, and the inner surface wall of the hole 110 is movably inserted with a bidirectional threaded rod 111, and a motor 112 is arranged on one side of the outer wall of the bidirectional threaded rod 111. The outer wall of the bidirectional threaded rod 111 is threadedly connected with two movable slides 113, and the two movable slides 113 are fixedly connected with the two fixed plates 114. When the motor 112 is running, the bidirectional threaded rod 111 can be driven to rotate, so that the two movable slides 113 move relatively, and finally the The two fixed plates 114 are moved, which can reduce the number of manual interventions and adjustments, reduce the difficulty of operation and labor intensity, and can also realize automatic control, improve the polishing speed and efficiency, which helps to shorten the production cycle and reduce production costs. Secondly, a hydraulic cylinder 203 is fixedly installed on the top of the support frame 201, and a piston rod 204 is arranged at the output end of the hydraulic cylinder 203. The piston rod 204 is connected to the motor 205, and the motor 205 is connected to the polishing disc 207 through the rotating shaft 206. First, the operation of the hydraulic cylinder 203 drives the piston rod 204 to extend and retract, so as to Adjusting the height of the polishing disc 207 can ensure stable contact between the polishing disc 207 and the graphite ring body 116, reducing potential safety hazards. At the same time, the operation of the motor 205 can drive the rotating shaft 206 to rotate and rotate the polishing disc 207 to polish the graphite ring body 116. At the same time, when the device is running, the spring 103 between the connecting plate 102 and the workbench 105 enables the device to maintain a more stable operating state during the polishing process. This stability helps to reduce surface quality defects caused by vibration and impact, such as scratches, unevenness, and thus improve the polishing quality.
