Description

Technical Field

[0001] This utility model relates to a grinding tool for the bottom surface of an anode carbon block or carbon bowl. Background Technology

[0002] During the high-temperature roasting process, the surface of the anode carbon block may adhere to the covering auxiliary materials (such as metallurgical coke particles). If these adherent materials remain on the bottom surface of the carbon bowl, gaps will exist between the steel claws and the carbon bowl, affecting the tightness of the phosphorus pig iron casting. Grinding the bottom surface of the carbon bowl is a necessary step in the anode production and assembly process. Through physical surface treatment, the conductivity, connection, and chemical properties are optimized, ultimately achieving efficient, energy-saving, and safe operation of aluminum electrolysis.

[0003] The existing method of grinding the bottom and sides of the anode carbon block and carbon cup requires switching between two different tools, which results in low processing efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects and provide a grinding tool for the bottom surface of an anode carbon block and carbon bowl, which integrates grinding tools for the bottom and side surfaces of the carbon bowl to improve processing efficiency.

[0005] The technical solution to achieve the above objective is as follows: a grinding tool for the bottom surface of an anode carbon block / carbon bowl, comprising a milling cutter holder shaft, a plurality of cutter head seats being fitted on the hexagonal slide rod of the milling cutter holder shaft, two first mounting slots being mirror-imagely formed on the upper and lower end faces of each cutter head seat, four first mounting slots being evenly distributed on each cutter head seat, and a corresponding first cutting cutter head being detachably connected to each of the four first mounting slots by bolts, a pressure plate being fitted on the sliding shaft of the milling cutter holder shaft, a fixing nut being detachably connected to the threaded end of the milling cutter holder shaft, the fixing nut being in close contact with the pressure plate, and three second mounting slots being evenly formed on the base of the milling cutter holder shaft, and a corresponding second cutting cutter head being detachably connected to each of the second mounting slots by bolts.

[0006] Preferably, each of the first cutting tips is arranged in a spiral shape.

[0007] Preferably, a washer is tightly attached between the fixing nut and the pressure plate.

[0008] Preferably, each of the first cutting head and the second cutting head is made of cemented carbide material;

[0009] Preferably, each of the cutter head seats is in close contact with the other, and the uppermost cutter head seat is in close contact with the pressure plate.

[0010] Preferably, the milling cutter holder shaft is mounted on the drive shaft of the machine tool.

[0011] The beneficial effects of this utility model are: multiple cutter head seats are sleeved on the hexagonal slide bar of the milling cutter holder shaft, and a corresponding first cutting cutter head is detachably connected to each cutter head seat. A corresponding second cutting cutter head is detachably connected to the milling cutter holder shaft. The milling cutter holder shaft performs cutting at a certain rotation speed and feed speed. The first cutting cutter head removes most of the impurities on the side, and the second cutting cutter head cleans the impurities on the bottom surface. This can improve the processing efficiency of carbon cups.

[0012] When the first cutting head wears out, remove the fixing nut, washer, and multiple cutting head seats in sequence, then remove the first cutting head from the corresponding cutting head seat and replace it with a new first cutting head. When the second cutting head wears out, directly remove the corresponding second cutting head from the milling cutter holder shaft for replacement. This split installation structure can greatly reduce the subsequent maintenance cost of this tool. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] Example 1

[0021] Combination Figure 1-4 Specifically, a grinding tool for the bottom surface of an anode carbon block / carbon bowl includes a milling cutter holder shaft 1, multiple cutter head seats 2, multiple first cutting cutter heads 4, a pressure plate 5, a fixing nut 6, a second cutting cutter head 8, and a washer 9.

[0022] Specifically, multiple cutter head seats 2 are fitted on the hexagonal sliding rod of the milling cutter holder shaft 1. Each cutter head seat 2 has two mirror-image first mounting grooves 3 on its upper and lower end faces. The four first mounting grooves 3 on each cutter head seat 2 are evenly distributed. Each of the four first mounting grooves 3 is detachably connected to a corresponding first cutting cutter head 4 by bolts. A pressure plate 5 is fitted on the sliding shaft of the milling cutter holder shaft 1. A fixing nut 6 is detachably connected to the threaded end of the milling cutter holder shaft 1. The fixing nut 6 and the pressure plate 5 are in close contact. Three second mounting grooves 7 are evenly distributed on the base of the milling cutter holder shaft 1. Each second mounting groove 7 is detachably connected to a corresponding second cutting cutter head 8 by bolts. The cutter head seats 2 are in close contact with each other, and the uppermost cutter head seat 2 is in close contact with the pressure plate 5.

[0023] Specifically, each of the first cutting heads 4 is arranged in a spiral shape, and a washer 9 is tightly attached between the fixing nut 6 and the pressure plate 5. The washer 9 can increase the friction between the fixing nut 6 and the pressure plate 5, ensuring the stability of the tool structure.

[0024] Specifically, each of the first cutting heads 4 and the second cutting heads 8 is made of cemented carbide. Each of the first cutting heads 4 is designed according to the size of a common carbon cup, and can effectively cut impurities on the side of the carbon cup when rotating at high speed. Each of the second cutting heads 8 matches the shape of the bottom of the carbon cup, and its length and width are optimized according to the size of the bottom surface of the carbon cup to ensure that it can cover the entire bottom surface. The horizontal part of the second cutting head 8 is used to clean the bottom surface. The cemented carbide blade has high hardness and wear resistance.

[0025] Specifically, the milling cutter holder shaft 1 is mounted on the drive shaft of the machine tool. When cleaning the carbon cup, the machine tool first controls the milling cutter disc to approach the side of the carbon cup and cuts at a certain speed and feed rate. The side cleaning cutter removes most of the impurities on the side, and the bottom cleaning cutter removes the impurities on the bottom.

[0026] Example 2

[0027] When the first cutting head 4 wears out, the tool needs to be removed from the machine tool first. Then, tighten the fixing nut 6 and remove the fixing nut 6, the washer 9 and multiple tool head seats 2 in sequence. Then, remove the first cutting head 4 from the corresponding tool head seat 2 and replace it with a new first cutting head 4. Finally, reverse the above steps to reassemble the tool.

[0028] When the second cutting head 8 wears out, the corresponding second cutting head 8 can be directly removed from the milling cutter holder shaft 1 and replaced.
