The anode is composed of an aluminum guide rod, steel claws and explosive blocks welded to both ends of the aluminum guide rod, and a carbon block. In the electrolytic aluminum production process, the aluminum guide rod is prone to top bending, top cracking and damage, so it needs to be straightened and repaired. When straightening and repairing, it is necessary to cut off the steel claws and explosive blocks at both ends of the aluminum guide rod first, straighten the aluminum guide rod, re-bevel one end of the aluminum guide rod and mill the surface of the aluminum guide rod flat, and then weld the steel claws and explosive blocks to both ends of the aluminum guide rod.

[0003] In the prior art, cutting steel claws and explosive blocks, straightening aluminum guide rods, beveling aluminum guide rod ends, milling surfaces, and re-welding steel claws and explosive blocks are completed on different single-unit equipment, especially cutting steel claws and explosive blocks, straightening aluminum guide rods, and re-welding steel claws and explosive blocks, which are basically completed manually.

[0059] The working process of the present invention is further described below.

[0060] Example 1

[0061] The on-site staff operated the overhead crane to transport the aluminum guide rod A with steel claws B to be repaired to the Figure 1The aluminum guide rod is placed horizontally on the feeding shearing device shown in the figure. The aluminum guide rod is transported to the side of the shearing device 3 under the drive of the conveying rack 2. After the photoelectric sensor on the shearing device detects that the aluminum guide rod is in place, the control system controls the conveying rack to stop moving forward. Then the pushing mechanism 8 is activated to push the aluminum guide rod to the bottom of the disk saw 32, and the aluminum guide rod is pressed by the pressing rod 81. After that, the shearing device starts to move and drives the disk saw 32 downward under the drive cylinder to cut off the steel claw B. After the steel claw is cut off. The shearing device rises back to its position, and the pushing mechanism 8 also retreats. Next, the conveying rack 2 is activated to convey the aluminum guide rod after the steel claws are cut off to the guide rod receiving slot 9 that falls into the aluminum guide rod pushing device, and is pushed by the second pushing oil cylinder 10 to the subsequent aluminum guide rod automatic straightening device, and enters from the trumpet-shaped guide entrance 13 of the aluminum guide rod automatic straightening device. The motors 163 arranged on both sides of the rack drive the sprocket and chain rotating mechanism 16 to rotate, and the sprocket and chain rotating mechanism then drive the upper and lower rows of vertical wheels to rotate; the aluminum guide rod moves forward driven by the two sets of vertical wheels (driving wheels). In this process, the aluminum guide rod passes through the two sets of vertical wheels and The two groups of horizontal wheels and four groups of working pulleys are straightened after being extruded at the same time, and are sent out from the exit 14 to the aluminum guide rod fixing table 18 of the subsequent beveling and cutting device. After the aluminum guide rod is pressed by the clamping mechanism 19 on the fixing table, the milling cutter 224 of the milling device 22 is first reciprocated along the length direction of the aluminum guide rod to mill the top surface of the aluminum guide rod, and then the turning mechanism 20 lifts the aluminum guide rod and turns it 90° and then falls down, and then the milling cutter mills the aluminum guide rod and turns it to the second surface of the top surface, and then the aluminum guide rod is continued to be turned over and milled until the four surfaces of the aluminum guide rod are milled. After the milling operation is completed, the aluminum guide rod is transported to the mobile cutting table 21 by the conveying roller 181, the end of the aluminum guide rod is sawed flat by the end saw 212, and then the beveling saw 211 bevels the upper and lower surfaces of the aluminum guide rod end, and then the turning mechanism 20 lifts the aluminum guide rod and turns it 90 degrees, and then the beveling saw 211 bevels the upper and lower surfaces of the aluminum guide rod after turning, completing the beveling operation of the four surfaces of the aluminum guide rod end. After that, the aluminum guide rod A is pushed out from the mobile cutting table and sent to the subsequent automatic welding device, and is transported by the material rack 23 to the position between the material rack and the guide rod rotating mechanism 26, and is aligned with the steel claw B placed on the platform 25. After the second sensing device 233 on the material rack senses that the aluminum guide rod to be welded is in place, the information is transmitted to the control system, and the control system starts the mounting seat drive motor 263, drives the screw rod 272 to rotate, drives the mounting seat forward, and makes the four open clamps 264 surround the outer periphery of the aluminum guide rod. Then, the worm gear drive motor 268 is started to drive the worm gear 267 to rotate an angle, so that the four clamps are synchronously displaced toward the center of the worm gear, thereby achieving the clamping of the aluminum guide rod by the clamps.Then the welding manipulator 1 starts welding the first side (top side) of the aluminum guide rod with the steel claw. After the first sensing device 243 on the welding manipulator senses that the welding of the first side is completed, the first sensing device transmits information to the control system. The control system then controls the main gear drive motor 266 to start, and controls the aluminum guide rod to rise to a certain height through the lifting cylinder 234. The main gear drive motor drives the internal gear 269 to move through the main gear 265, and then drives the chuck seat 262 to rotate. The control system controls the rotation angle of 90°, so that the chuck holding the aluminum guide rod and the steel claw connected by the preliminary welding are rotated as a whole, and the aluminum guide rod and the steel claw are turned over 90°. Then the welding manipulator continues to weld the aluminum guide rod and the steel claw to the second side of the top surface; after the welding of the second side is completed, the first sensing device transmits information to the control system again, and the control system controls the rotating chuck seat to rotate 90°, and the aluminum guide rod and the steel claw are rotated one more side for welding. In this way, the aluminum guide rod and the steel claw are alternately turned over and welded until the four sides connected to the aluminum guide rod and the steel claw are welded. When the four surfaces are welded, the rotating chuck releases the aluminum guide rod, the rotating chuck seat returns to its original position, the lifting cylinder controls the aluminum guide rod to return to its original position, and the aluminum guide rod with welded steel claws is placed on the rack 23. The four chucks are released, and the guide rod rotating mechanism returns to its original position to wait for the next work instruction. The conveyor chain 231 conveys the welded aluminum guide rod to the next station, and the entire operation process is completed.

[0062] By continuously feeding the aluminum guide rods to be repaired according to the above operation process, continuous and efficient repair of the aluminum guide rods can be achieved, and the repair quality can be ensured to be stable. The automatic production line for repairing aluminum guide rods disclosed by the present invention is automatically controlled by PLC, and manual intervention is required only when the system fails and stops, so that safe production of high-efficiency automatic production lines can be achieved.
