Description

Technical Field

[0001] This utility model relates to the field of cutting tools for machining anode carbon blocks, and in particular to a grinding tool for the outer arc of anode carbon blocks. Background Technology

[0002] The anode structure of an aluminum electrolytic cell is usually arc-shaped or circular (such as the anode group arrangement in a prebaked cell). The outer arc machining is to ensure that the shape of the anode carbon block and the inner wall of the electrolytic cell, as well as the splicing structure of adjacent carbon blocks, are precisely matched to ensure a tight fit during installation and avoid problems such as leakage and uneven current distribution caused by shape errors.

[0003] The smooth, precisely shaped outer arc surface after machining reduces the adhesion resistance of electrolytes (such as cryolite melt) on the anode surface, optimizes electrolyte flow, and reduces bubble retention at the anode-electrolyte interface, thereby improving electrolysis efficiency. The rounded corners of the outer arc also prevent stress concentration and reduce crack formation.

[0004] Existing cutting tools are often not specific enough, making it difficult to achieve efficient and precise machining of the special outer arc structure on carbon blocks. Furthermore, existing machining tools are often integrally formed, resulting in high maintenance costs later on. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing defects and provide a grinding tool for the outer arc of an anode carbon block, which can efficiently and accurately process the outer arc of the carbon block, and adopts a split design to save on later maintenance costs.

[0006] The technical solution to achieve the above objective is: an outer arc grinding tool for an anode carbon block, including a milling cutter disc, a connecting shaft connected to the upper surface of the milling cutter disc, and a plurality of first support plates uniformly connected to the lower surface of the milling cutter disc. A first arc groove is opened on the outer side of each first support plate, and a corresponding cutting edge structure is detachably connected to each first support plate by bolts.

[0007] Preferably, the blade structure includes a second support plate, an arc blade, and a straight blade. The second support plate is detachably connected to the first support plate by bolts. The second support plate has a second arc-shaped groove, on which the arc blade is installed. The lower end of the second support plate has a mounting groove, in which the straight blade is installed.

[0008] Preferably, each of the first support plates is also provided with a plurality of first through holes evenly distributed, and the second support plate is provided with a plurality of corresponding second through holes, and bolts are inserted into each of the first through holes and the corresponding second through holes.

[0009] Preferably, the end of the bolt is fitted with a corresponding washer and nut.

[0010] Preferably, the connecting shaft is mounted on the processing robot.

[0011] Preferably, the cutting edge of the arc-shaped blade extends out of the first arc-shaped groove and the second arc-shaped groove.

[0012] Preferably, the arc-shaped blade is tangent to the outer arc of the carbon block.

[0013] Preferably, the cutting edge of the straight blade extends out of the mounting groove.

[0014] The beneficial effects of this utility model are as follows: multiple first support plates are evenly connected to the lower surface of the milling cutter disc, and a first arc groove is opened on the outer side of each first support plate. A second support plate is detachably connected to the first support plate by bolts. A second arc groove is opened on the second support plate, and an arc blade is installed on the second arc groove. Through the cutting action of the arc blade and the planar milling of the straight blade, impurities and excess carbon layer on the outer arc surface are removed. This enables efficient and precise machining of the outer arc on the carbon block. Furthermore, the split design allows for the disassembly and replacement of damaged cutting edge structures, saving on subsequent maintenance costs. Attached Figure Description

In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-3As shown, an outer arc grinding tool for an anode carbon block includes a milling cutter disc 1, a connecting shaft 2, a first support plate 3, and a cutting edge structure.
