[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an ultra-high power graphite electrode high-efficiency grinding device, comprising:

[0032] Grinding box 1 is equipped with a high-efficiency grinding mechanism. It should be noted that the high-efficiency grinding mechanism can efficiently grind the ultra-high power graphite electrode 12, and can also remove dust during the grinding process.

[0033] The high-efficiency grinding mechanism includes a synchronous hydraulic cylinder 3, a push plate 4, a rotating shaft 5, a top frame 6, a power motor 7, a connecting shaft 8, a rubber anti-slip pad 10, a side hydraulic cylinder 13, and a grinding rod 14.

[0034] The hydraulic rod of the synchronous hydraulic cylinder 3 is fixedly connected to the push plate 4, the rotating shaft 5 is rotatably mounted on the push plate 4, and the top frame 6 is fixedly connected to the rotating shaft 5. It should be noted that the top frame 6 can rotate relative to the push plate 4. After the top frame 6 is placed on the grinding box 1, the top frame 6 can be limited.

[0035] The power motor 7 is fixedly installed at the bottom of the grinding box 1, the connecting shaft 8 is rotatably installed on the top frame 6, and the output end of the power motor 7 and the bottom of the connecting shaft 8 are both fixedly provided with turntables 9. The rubber anti-slip pads 10 are fixedly installed on the turntables 9, and the side hydraulic cylinder 13 is fixedly installed on the grinding box 1. The hydraulic rod of the side hydraulic cylinder 13 is fixedly connected to the grinding rod 14.

[0036] Using the aforementioned high-efficiency grinding mechanism, the ultra-high power graphite electrode 12 is placed on the lower rubber anti-slip pad 10. Activating the synchronous hydraulic cylinder 3 causes the upper turntable 9 to move the rubber anti-slip pad 10 downwards, allowing the two rubber anti-slip pads 10 to abut and limit the ultra-high power graphite electrode 12. At this time, the top frame 6 is fitted onto the grinding box 1, which limits its position. Activating the side hydraulic cylinder 13 causes the grinding rod 14 to abut against the outer side of the ultra-high power graphite electrode 12. Then, activating the power motor 7 causes the ultra-high power graphite electrode 12 to rotate, and the grinding rod 14 performs high-efficiency grinding on the rotating ultra-high power graphite electrode 12.

[0037] Specifically, the high-efficiency grinding mechanism also includes a rubber radial friction strip 11 and a three-way suction pipe 17. The rubber radial friction strip 11 is integrally set with the rubber anti-slip pad 10. The rubber radial friction strip 11 on the two rubber anti-slip pads 10 abuts against the same ultra-high power graphite electrode 12. The three-way suction pipe 17 is fixedly installed on the top frame 6.

[0038] Through the aforementioned efficient grinding mechanism, the three-way suction pipe 17 is connected to the external suction hose, which in turn is connected to the vacuum cleaner. During the grinding process, the three-way suction pipe 17 can remove the dust generated during grinding in the enclosed space, resulting in good dust removal. The rubber radial friction strip 11 can firmly press the ultra-high power graphite electrode 12 against it. The frictional force applied by the rubber radial friction strip 11 to the ultra-high power graphite electrode 12 is much greater than the frictional force generated between the grinding rod 14 and the ultra-high power graphite electrode 12 during grinding, thus enabling the ultra-high power graphite electrode 12 to rotate stably.

[0039] Specifically, the inner side of the top frame 6 contacts the outer side of the grinding box 1, the three-way dust suction pipe 17 is connected to the inside of the top frame 6, and the side of the push plate 4 contacts the top frame 6. It should be noted that this facilitates the removal of dust generated during the grinding process.

[0040] Specifically, a support frame 16 is fixedly installed at the bottom of the grinding box 1, and side supports 2 are fixedly installed on both sides of the grinding box 1. The synchronous hydraulic cylinder 3 is fixedly installed on the top of the side supports 2. It should be noted that this is to facilitate the assembly of the synchronous hydraulic cylinder 3.

[0041] Specifically, a stabilizing rod 15 is fixedly installed on the grinding rod 14, and a stabilizing hole is opened on the grinding box 1. The stabilizing rod 15 is slidably installed in the stabilizing hole. It should be noted that this allows the grinding rod 14 to slide stably in the lateral direction.

[0042] Working principle:

[0043] S1: Place the ultra-high power graphite electrode 12 on the rubber anti-slip pad 10 below, start the synchronous hydraulic cylinder 3, the synchronous hydraulic cylinder 3 drives the push plate 4 to move, the push plate 4 drives the top frame 6 to move through the rotating shaft 5, the top frame 6 drives the connecting shaft 8 to move, which in turn causes the upper turntable 9 to drive the rubber anti-slip pad 10 to move downward, so that the two rubber anti-slip pads 10 abut and limit the ultra-high power graphite electrode 12;

[0044] S2: At this time, the top frame 6 is fitted on the grinding box 1, so that the ultra-high power graphite electrode 12 is in a closed space during grinding, and the top frame 6 can be limited. The side hydraulic cylinder 13 is activated so that the grinding rod 14 abuts against the outer side of the ultra-high power graphite electrode 12.

[0045] S3: The rubber radial friction strip 11 can firmly press the ultra-high power graphite electrode 12 against the ultra-high power graphite electrode 12. The frictional force applied by the rubber radial friction strip 11 to the ultra-high power graphite electrode 12 is much greater than the frictional force generated by the grinding rod 14 and the ultra-high power graphite electrode 12 during the grinding process. This allows the ultra-high power graphite electrode 12 to rotate stably. Start the power motor 7, so that the turntable 9 below drives the rubber anti-slip pad 10 to rotate. This allows the ultra-high power graphite electrode 12 to rotate. The ultra-high power graphite electrode 12 drives the turntable 9 above and the rubber anti-slip pad 10 to rotate. The grinding rod 14 performs efficient grinding on the rotating ultra-high power graphite electrode 12.

[0046] S4: The three-way suction pipe 17 is connected to the external suction hose, and the suction hose is connected to the vacuum cleaner. During the polishing process, the three-way suction pipe 17 can remove the dust generated during the polishing process in the enclosed space, with good dust removal effect.

[0047] S5: After grinding, start the synchronous hydraulic cylinder 3 to move the top frame 6 upward. After the top frame 6 moves to a certain height, rotate the top frame 6 and then take out the ground ultra-high power graphite electrode 12.

[0048] The above provides a detailed description of the ultra-high power graphite electrode high-efficiency grinding device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
