[0002] The cathode roller is one of the core components in the aluminum electrolysis cell. During the aluminum electrolysis process, the cathode roller carries the current and provides the necessary electron path for the electrolysis reaction. Its main function is to receive the current from the power supply and distribute it to the corresponding areas of the electrolysis cell to promote the reduction of aluminum ions and the deposition of aluminum.

[0003] When the existing cathode roller is in operation for a long time, there is a probability that hydrogen will appear in the inner cavity of the cathode roller. There have been explosions during maintenance drilling. Later, wet drilling and static degassing were all used. Therefore, each degassing requires manual operation, which makes the operation more troublesome. In addition, during the production and manufacturing process of the cathode roller, the cathode roller base and the end cover need to be welded to each other to ensure that the cathode roller can form a whole. However, in actual welding, the operator needs to place the cathode roller base in a closed space to ensure that welding debris does not splash, and then drive the end cover and the cathode roller base to cooperate before welding can be carried out.

The processed cathode roller end cover 7 and the center shaft 71 are installed on the flat plate 3, the center shaft 71 is first inserted into the sleeve 31, and the sleeve 31 is tightened as a whole by the locking bolt 311, thereby achieving the purpose of fixing the center shaft 71 and the cathode roller end cover 7.

The limit plate 333 ensures that the slide 33 and the limit rod 331 will not separate.

[0030] The implementation principle of a novel cathode roller production method of this embodiment is as follows: First, the operator welds the cathode roller end cover 7 and the center shaft 71 together, installs the welded workpiece on a punching machine, and opens through holes on the end faces of the cathode roller end cover 7 and the center shaft 71. By performing hole opening treatment on the surface of the cathode roller end cover 7 and the center shaft 71, the cathode roller can be unobstructed inside and outside, and there is no accumulation of hydrogen. There is no need for manual exhaust operation at a later stage, which makes the operation simpler and facilitates improving the efficiency of later maintenance.

[0031] Then the operator installs the processed cathode roller end cover 7 and center shaft 71 on the flat plate 3, first inserts the center shaft 71 into the sleeve 31, and tightens the sleeve 31 as a whole by tightening the locking bolt 311, thereby achieving the purpose of fixing the center shaft 71 and the cathode roller end cover 7.

[0032] Then, the cathode roller base 6 is placed as a whole on the mounting groove 21 of the supporting platform 2 .

[0033] Then the operator starts the hydraulic system (the hydraulic system is a prior art, the working principle will not be described here, and it is not described in the drawings), the hydraulic system drives the connected expansion plate 34 to slide downward, the expansion plate 34 can drive the flat plate 3 to slide vertically downward, and the cathode roller end cover 7 can slide vertically downward and move toward the surface of the cathode roller base 6.

[0034] When the flat plate 3 slides downward, the flat plate 3 drives the top rod 32 and the slide seat 33 at the bottom to slide downward. The slide seat 33 can slide downward along the limit rod 331 at this time. The limit spring 332 can be compressed during the sliding process. The compressed limit spring 332 is convenient for the subsequent resetting operation. In addition, a limit plate 333 is installed on the limit rod 331. The limit plate 333 ensures that the slide seat 33 and the limit rod 331 will not separate.

[0035] When the top rod 32 slides downward, the top rod 32 can drive the top plate 321 at the bottom to slide downward, and the top plate 321 drives the bottom sliding rod 322 to slide downward. The sliding rod 322 can now slide in the bar groove 231 of the rocker arm 23, thereby driving the rocker arm 23 to rotate around the base 234. Until the rocker arm 23 rotates to a horizontal state, the side plate 232 rotates to a vertical state, and the pressure rod 52 on the side plate 232 and the side wall of the pressure plate 427 correspond to each other, and the sliding rod 322 slides to the connection between the slot 233 and the bar groove 231.

[0036] During the rotation of the rocker arm 23, the guide slider 24 at the end of the rocker arm 23 can slide on the guide rod 241, and the guide spring 243 on the guide rod 241 is compressed, and the guide spring 243 is used to facilitate the subsequent resetting operation. When the guide slider 24 slides, the support platform 2 can slide downward at this time, and the support platform 2 drives the cathode roller base 6 to slide downward until the rocker arm 23 rotates to a horizontal state. At this time, the support platform 2 stops moving, and finally the cathode roller base 6 is installed inside the processing table 1.

[0037] When the support platform 2 slides downward, the reset rod 22 at the bottom of the support platform 2 slides inside the reset cover 221, and the reset plate 222 at the end of the reset rod 22 slides inside the reset cover 221, thereby resetting the reset spring 223, and the original reset spring 223 is in a compressed state.

[0038] When the rocker arm 23 rotates to a horizontal state, the cathode roller base 6 is in a stationary state. When the top rod 32 and the slide bar 322 continue to slide downward, the slide bar 322 can slide into the slot 233. Then the slide bar 322 can press the extrusion block 51 through the inclined surface 511. At this time, the extrusion block 51 drives the partition 521 to slide inside the extrusion cover 5 and squeezes the positioning spring 522. The positioning spring 522 facilitates the subsequent resetting operation. After the partition 521 slides, the pressure rod 52 begins to move outward.

[0039] The pressure rod 52 can now squeeze the pressure plate 427, and the pressure plate 427 drives the side rod 426 to slide, and the side rod 426 pushes the positioning slide block 424 to slide on the positioning slide rail 425, and the swing arm 423 of the side wall of the positioning slide block 424 drives a pair of synchronous plates 411 to slide on the auxiliary rod 42, and compresses the compression spring 421, and the compression spring 421 is used to facilitate the later reset operation, and the synchronous plate 411 can finally drive the auxiliary slide block 4 to slide in the auxiliary slide groove 41, and then drive the connecting plate 43 and the moving rod 431 to slide, and the moving rod 431 drives the clamping plate 432 to move toward the center to clamp and fix the cathode roller base 6, and the flat plate 3 is always moving downward at this time, and finally the cathode roller end cover 7 can be moved to the welding position of the cathode roller base 6, and then the welding operation is completed by the welding gun.
