Description

Technical Field

[0001] This utility model relates to the field of electropolishing technology, and in particular to an electropolishing device. Background Technology

[0002] Stainless steel electrolytic polishing uses the workpiece as the anode and an insoluble metal as the cathode, with both electrodes simultaneously immersed in an electrolytic tank. Direct current is applied to produce selective anodic dissolution, gradually smoothing the workpiece surface and increasing its gloss. However, due to the temperature inconsistency between the bottom and top layers of the static electrolytic water, the polishing degree on both sides is incorrect, resulting in uneven polishing.

[0003] Publication No. CN219547147U discloses an electrolytic polishing device for uniform processing, including a polishing tank and a rotatable polishing device. The rotatable polishing device is arranged on the upper outer wall of the polishing tank near the front and rear sides. The rotatable polishing device includes a rotating shaft, a fixed head, a support rod, and a turntable. The fixed head is arranged at the rear edge of the upper outer wall of the polishing tank, and the support rod is arranged at the front end of the fixed head. The turntable is arranged in the middle position of the support rod, and the rotating shaft is arranged downward through the middle position of the upper part of the turntable. The rotating shaft can be fixed and rotated through the turntable. After the rotatable polishing device is installed, when polishing the parts hanging on the hanging rod, it drives the polishing parts to rotate in the electrolytic tank, thereby reducing the temperature difference between the upper and lower layers of the electrolytic polishing water. When the parts rotate in the electrolytic polishing tank, the water-receiving area of ​​the parts can be increased, making the polishing more uniform.

[0004] The aforementioned device requires manual operation by a worker to rotate the hanging rack using a crank handle. However, during the polishing process of the workpieces on the rack, the electrolyte may release harmful gases and vapors, which could easily affect the health of the workers. Therefore, there is a need for an electrolytic polishing device. Utility Model Content

The first and second gas passages connect the gas in several adsorption chambers, facilitating the purification process. The gas is then transported to the outlet main pipe through the gas delivery pipe and the gas guide pipe. Finally, the gas enters the bottom of the electrolytic cell through the outlet branch pipe and the outlet hole. The gas agitates the electrolyte in the electrolytic cell, making the electrolyte mixture more uniform. Attached Figure Description
