Description

Technical Field

[0001] This invention belongs to the field of aluminum electrolytic anode production and the field of automatic repair production line for aluminum electrolytic anode guide rods, specifically relating to an automatic welding and repair production line for aluminum electrolytic anode guide rods. Background Technology

[0002] As a key component of electrolytic aluminum production, the anode guide rod assembly is a crucial link in the current path. It is characterized by its large number, susceptibility to damage, and difficulty in repair, making it a focus of routine maintenance for enterprises. After a short period of use in the tank, cracks and corrosion may occur at the weld joint between the anode guide rod and the explosive block. In such cases, the guide rod needs to be disassembled and replaced with a new explosive block for reuse. Currently, factory replacements are primarily done manually. The repair process involves separating the weld joint between the guide rod and the explosive block using a pulse pile breaker, then manually chamfering the four edges using a grinder, and finally manually welding it to a new explosive block. Due to limitations in welding technology and the uncertainty of manual operation, this can lead to uneven weld surfaces, poor welding precision, misalignment between the guide rod and the steel claw beam, incomplete welds, easy detachment or cracking of the guide rod, and a short service life, significantly increasing the enterprise's operating costs and the number of workers required.

[0037] This invention works as follows:

[0038] Overall workflow: The anode guide rod assembly is manually hoisted onto the flipping and positioning machine 3 by a crane for initial positioning. After positioning, the personnel move to a safe position and press the welding line program start button. The flipping and positioning machine 3 flips the guide rod 14 onto the tooling table of the rotary worktable 1. The drive motor 17 and lifting roller 12 are used to adjust the front and rear distance to align it with the cutting position of the cutting machine 2. The circular saw cuts upward to separate the aluminum guide rod 14 from the old explosive block 58. After separation, the flipping and positioning machine 3 automatically returns to the dismantling device 5 after returning to its original position to dismantle the old explosive block 58. During this process... When the rotary worktable 1 receives a signal from the flipping positioner 3 passing the origin, it rotates 90° to reach the chamfering device 6. The chamfering machine uses two cylinders to adjust and chamfer the aluminum guide rod 14. The C-shaped positioner 13 on the rotary tooling table 1 rotates the aluminum guide rod 14, automatically chamfering the four edges of the guide rod. After chamfering, the rotary worktable 1 rotates 90° again to reach the welding device 8. The welding robot 7 welds the upper edge. After welding one edge, the remaining three edges are welded separately under the adjustment of the C-shaped positioner 13 and the reduction motor II56. After welding, the rotary worktable rotates 90° again to reach the unloading device for manual unloading.

[0039] The specific workflow of each device is as follows:

[0040] See Figure 1The anode guide rod assembly is manually hoisted onto the flipping and positioning machine 3 by a crane for initial positioning. After positioning, the personnel move to a safe position and press the welding line program start button. The flipping and positioning machine 3 flips the guide rod onto the tooling table of the rotary worktable 1. The drive motor 17 and the lifting roller 12 are adjusted to align it with the cutting position of the cutting machine 2. The disc saw blade 16 cuts upward to separate the aluminum guide rod 14 from the old explosive block. After separation, the flipping and positioning machine 3 automatically returns to the dismantling device 5 after the original position to dismantle the old explosive block. During this process, the rotary worktable 1 receives the flipping and positioning machine. When the positioner 3 passes the signal from the origin, it rotates 90° to reach the chamfering device 6. The chamfering machine uses the upper large-diameter cylinder 29 and the lower standard cylinder 35 to adjust and chamfer the aluminum guide rod 14. The C-shaped positioner 13 on the rotating tooling table 1 causes the aluminum guide rod 14 to rotate, achieving automatic chamfering of the four edges of the guide rod. After chamfering, the rotating worktable 1 rotates 90° again to reach the welding device 8. The welding robot 7 welds the upper edge. After welding one edge, the remaining three edges are welded separately under the adjustment of the C-shaped positioner 13 and the reduction motor II56. After welding, the rotating worktable rotates 90° again to reach the unloading device for manual unloading.

[0041] See Figure 2 The aluminum guide rod 14 is placed into the slot of the C-shaped positioner 13 by the flipping positioner 3. Then, under the drive of the C-shaped positioner motor, it is clamped and can rotate. Under the rotation of the turntable 11, the tooling table and the aluminum guide rod 14 are moved together between the various devices.

[0042] See Figure 3 Initially, the flipping positioner 3 is at the origin, and the disc saw blade 16 of the cutting machine 2 is inside the equipment. After manually suspending the anode guide rod assembly on the flipping positioner 3, the module handle is cranked, causing the positioning clamp 18 to move forward and clamp the guide rod assembly's steel claw head. Then, the brake stop 19 is locked with bolts. After personnel leave, the start button is pressed, and the flipping positioner 3 flips, allowing the aluminum guide rod 14 to enter the C-shaped positioner 13 on the tooling table and be fixed and clamped. The disc saw blade 16 rotates at high speed and moves upward, cutting the aluminum guide rod 14 and the steel claw head apart. After separation, the disc saw blade 16 retracts and stops rotating. The flipping positioner 3 automatically returns to the origin and rotates the steel claw head upward. Upon receiving the origin signal, the rotating worktable rotates to the next device.

[0043] See Figure 4 When the aluminum guide rod 14 reaches the chamfering device 6, the large-diameter cylinder 29 extends forward to the designated position 1. The motor 37 starts and drives the rotating shaft 39 to rotate via the conveyor belt 40. The standard cylinder 35 extends to achieve cutting feed. After cutting one edge, the aluminum guide rod 14 rotates 90° and extends to the designated position 2 via the large-diameter cylinder 29 for cutting. By repeating the above actions, this device only needs to use two positions to process all four edges of the guide rod.

[0044] See Figure 5 and Figure 6 After the aluminum guide rod 14 is in place, the hydraulic cylinder 45 extends and the new explosive block 50 contacts the cross-section of the aluminum guide rod 14. The robot performs welding under the guidance of the welding torch 54 guided by the light sensor. The heat generated during welding is absorbed by the circulating cooling block 51 for rapid cooling. Welding in four directions (up, down, left, and right) is achieved by the C-positioner 13 and the geared motor II 56. After welding is completed, the pneumatic chuck 52 opens, and the hydraulic cylinder 45 retracts, causing the pneumatic chuck 52 to retract. The rotating worktable 1 rotates to the next device for unloading. A new explosive block 50 is manually loaded back into the chuck to await the next welding operation.

[0045] See Figure 7 When the flipping and positioning machine 3 arrives at the dismantling device 5 with the workpiece to be dismantled, the handwheel 28 on the milling head 27 is manually turned to adjust the vertical direction of the milling cutter 57 so that the milling cutter 57 is aligned with the welding point to be milled, and the entire plane under the old explosive block is machined by relying on the X, Y and Z directions.
