Description

Technical Field

[0001] The invention relates to the field of electrolytic polishing, and in particular to a stainless steel pipe inner wall electrolytic polishing device and a processing method thereof. Background Art

[0002] Electrolytic polishing is an advanced metal surface treatment technology. Electrolytic polishing uses the workpiece as the anode and the insoluble metal as the cathode. The two electrodes are immersed in the electrolytic cell at the same time, and a DC ionization reaction is passed to produce selective anodic dissolution, thereby achieving the effect of removing fine burrs on the workpiece surface and increasing the brightness. It is mainly used in metal manufacturing, automotive industry, aerospace industry, electronic and electrical industry, medical equipment, jewelry processing, and architectural decoration.

[0003] The patent application with announcement number CN205275772U is an electrolytic polishing device using a phosphorus-free electrolytic polishing liquid, which includes an electrolytic polishing tank, in which at least one cathode copper tube and one anode copper tube are arranged, and a plurality of cathode plates connected to the cathode copper tube; both ends of the cathode copper tube and the anode copper tube are mounted on the inner walls of the opposite sides of the electrolytic polishing tank, and are parallel to the bottom of the electrolytic polishing tank; the cathode copper tube is located between the anode copper tube and the side wall of the electrolytic polishing tank; a plurality of cathode plates are arranged along the length direction of the cathode copper tube and attached to the inner wall of one side of the electrolytic polishing tank; the cathode copper tube is connected to each cathode plate through a conductive copper sheet. The utility model can improve the processing accuracy of the equipment, high quality stability, and high production efficiency. It is better to use environmentally friendly phosphorus-free electrolytic polishing liquid for processing to avoid "phosphorus" pollution to the environment and water bodies.

[0004] During use, the existing electrolytic polishing device can generally only perform electrolytic polishing on the surface of an object. When the inner wall of a stainless steel pipe needs to be polished, it is difficult to act on its inner wall, resulting in difficulties in internal polishing. In addition, a large amount of floating electrolytic foam residue will be generated when the metal pipe is arranged. Since the electrolytic polishing pool is large, the residue is difficult to clean. In the existing polishing process, the stainless steel pipe needs to be fixed. The existing fixing method requires hoisting or the lifting platform of the electrolytic pool itself to complete the immersion of the stainless steel pipe and the electrolyte. This method is relatively complicated and cumbersome to operate, which affects the preparation cycle, thereby greatly reducing the overall efficiency of electrolytic polishing. In the existing electrolytic polishing process, the residue generated by polishing inside the stainless steel pipe wall is difficult to discharge in time, and secondary rinsing is required after polishing, which affects the electrolytic polishing effect and increases the cumbersomeness of the operation.

[0064] S1: The stainless steel tubes are placed into the fixing grooves 208 one by one, and the connecting rod 301 is rotated to drive the fixing half ring 307 to move into the fixing groove 208. At this time, due to the downward pressure of the connecting rod 301, the fixing seat 202 moves into the connecting frame 201, and the lock 302 and the connecting rod 301 are engaged, so that the stainless steel tube is fixed and immersed in the electrolyte;

When the electrolytic rod 104 moves, it can drive the filter bucket 511 to move in the electrolyte, and the residue floating on the surface can be collected, thereby completing the electrolytic polishing of the inner wall of the entire stainless steel pipe.

[0067] like Figure 1-10 As shown, by placing the stainless steel tube into the fixing groove 208 inside the fixing seat 202, the connecting rod 301 is rotated at this time, so that the connecting rod 301 drives the fixing half ring 307 to move and fit above the stainless steel tube, and with the continuous downward pressure, the fixing seat 202 moves into the connecting frame 201, so that the stainless steel tube in the fixing groove 208 can be completely immersed in the electrolyte, and after the fixing seat 202 moves into place, the stainless steel tube and the electrolytic rod 104 are just at the same horizontal position.
