As the central nervous system of the anode, the quality of the electrolytic aluminum anode guide rod not only affects the stable production of the electrolytic cell, but also affects various economic and technical indicators of electrolysis. However, the anode guide rod will inevitably be bent during transportation and electrolytic cell. After the bent guide rod is installed on the busbar with the anode carbon block, the anode carbon block and the bottom surface of the tank are not parallel, which affects the normal production of electrolytic aluminum. During assembly and production, the residual aluminum guide rod and steel claws can be recycled after being calibrated. The anode guide rod straightening is set in front of the steel claw inspection station. After the guide rod steel claw is straightened, it is sent to the guide rod straightening equipment for straightening.
Design of aluminum anode rod straightening
The anode guide rod and steel claw integrated straightening device is composed of base, turntable, lifting mechanism, straightening mechanism, hydraulic system, electric control system and other parts. The three oil cylinders on the fuselage are retractable fulcrums, and the bending parts of the guide rod and the steel claw bracket are pressure-straightened in the form of simply supported beams. The straightening mechanism can rotate or revolve.

The key technology of electrolytic aluminum anode rod straightening:
(1) The four sides of the anode aluminum guide rod can be straightened in all directions, and the problem of straightening with the steel claws;
(2) The straightening force of different types of anode aluminum guide rods Matching value, that is, the problem of setting the initial value of the cylinder pressure;
(3) The optimization problem of the mechanical strength and structure of the straightening device itself.
A new type of electrolytic aluminum anode guide rod straightening device is designed, with three unique straightening cylinders working together, the body rotates 360° and extends up and down, straightening the anode guide rod and steel claw at the same time, the straightening effect is good, and at the same time, Reduce the input cost; solve the problem that the straightening force of the electrolytic aluminum anode guide rod is difficult to define, calculate the deformation recovery of the guide rod corresponding to different straightening forces, and determine that the straightening force of the electrolytic aluminum anode guide rod needs to be set to 600kN as the critical value; Through the force analysis of the main body and main shaft of the key and important parts of the electrolytic aluminum anode guide rod device, the structure of the straightening device is optimized to improve its safety factor and the reliability of the whole machine.
