Description

Technical Field

[0001] This utility model relates to the field of metal small-diameter pipe processing technology, specifically to an electrolytic polishing machine for the inner wall of metal small-diameter pipes. Background Technology

[0002] Polishing the inner wall of small-diameter metal tubing (such as medical stainless steel needle tubes and precision hydraulic tubing) is a key process to improve its corrosion resistance, fluid conductivity, and hygiene level. However, existing internal wall electropolishing machines lack the function of recycling and reusing electrolyte during actual use. This results in the internal wall electropolishing machine being unable to effectively reuse the electrolyte, increasing processing costs and wasting energy. Therefore, we propose an internal wall electropolishing machine for small-diameter metal pipes. Utility Model Content

Used electrolyte can be discharged into the recycling tank 13 through the drain pipe 19. The filter screen 21 at the top of the recycling tank 13 can filter impurities in the electrolyte, realizing the recycling of the electrolyte. This not only reduces production costs and electrolyte waste but also meets environmental protection requirements, reducing environmental pollution. Example

[0017] Please see Figure 1 and Figure 2 The following technical solution is provided, specifically disclosed: A battery box 17 is fixedly connected to the bottom of the outer side of the mounting plate 9, and a storage battery 16 is fixedly connected to the inner cavity of the battery box 17. A charging port 15 is opened at the middle of one side of the battery box 17. The output end of the charging port 15 is unidirectionally electrically connected to the input end of the storage battery 16. A sliding groove 7 is opened on the inner side of the mounting plate 9. The inner cavity of the sliding groove 7 is slidably connected to one side of the movable plate 6 through a slider. A drain pipe 19 is fixedly connected to the bottom of the electrolyte placement tank 2. A control valve is provided in the inner cavity of the drain pipe 19. A mass sensor 14 is fixedly connected to one side of the recycling box 13 by bolts. A display is provided on the surface of the mass sensor 14. Support legs are fixedly connected to both the left and right sides of the bottom of the base plate 1, and anti-slip pads are provided at the bottom of the support legs. A PLC controller 18 is fixedly connected to the top of the outer side of the mounting plate 9 by bolts. The output end of the PLC controller 18 is unidirectionally electrically connected to the input end of the first electric telescopic rod 8 and the second electric telescopic rod 12. In practical use, by setting a limiting groove 10 and a limiting plate 4 on the top of the placement plate 3, and opening a limiting hole 5 on the limiting plate 4, the metal small-diameter pipe can be effectively limited and fixed. During the inner wall electrolytic polishing operation, the pipe will not easily shake or shift, ensuring the stability and accuracy of the polishing process and improving the polishing quality. At the same time, this fixing method is simple and convenient, making it easy for operators to place and remove the pipe, improving work efficiency. The PLC controller 18 on the top of the outer side of the mounting plate 9 is electrically connected to the first electric telescopic rod 8 and the second electric telescopic rod 12. Operators can automatically control the first electric telescopic rod 8 and the second electric telescopic rod 12 through the PLC controller 18. The first electric telescopic rod 8 can drive the movable plate 6 and the placement plate 3 to move up and down, making it easy to adjust the position of the pipe; the second electric telescopic rod 12 can drive the push plate 20 and the rolling roller 22 to move, realizing operations such as processing impurities in the recovery box 13. Automated control reduces manual intervention, improves the accuracy and stability of operation, and reduces the labor intensity of operators.

[0018] In use: The operator places the thin-diameter metal pipe requiring internal electrolytic polishing on the placement plate 3, inserting one end of the pipe into the limiting hole 5 of the limiting plate 4 and placing the other end in the limiting groove 10 to fix the pipe. An appropriate amount of electrolyte is added to the electrolyte placement tank 2 to provide the necessary liquid environment for the electrolytic polishing process. The first electric telescopic rod 8 is activated by operating the PLC controller 18. The output end of the first electric telescopic rod 8 extends or retracts, causing the movable plate 6 to slide up and down within the sliding groove 7. The movable plate 6, through the fixed rod 11, moves the placement plate 3 and the pipe fixed on it up and down, adjusting the pipe to a suitable position so that it is immersed in the electrolyte in the electrolyte placement tank 2. Once the pipe is immersed in the electrolyte, the equipment begins the internal electrolytic polishing operation. Under electrolysis, the metal on the inner wall of the pipe is gradually dissolved, achieving a polishing effect. After the electrolytic polishing operation is completed, the control valve inside the drain pipe 19 is opened, and the used electrolyte flows into the recovery tank 13 through the drain pipe 19. When the electrolyte passes through the filter screen 21 at the top of the recovery tank 13, impurities are filtered out and retained on the filter screen 21, while the filtered electrolyte remains inside the recovery tank 13, thus achieving electrolyte recovery. The PLC controller 18 is operated to start the second electric telescopic rod 12. The output end of the second electric telescopic rod 12 extends, driving the push plate 20 and the crushing roller 22 towards the filter screen 21. The crushing roller 22 crushes and pushes the impurities on the filter screen, concentrating them for easy subsequent cleaning. Throughout the operation, the mass sensor 14 on one side of the recovery tank 13 monitors the total mass of electrolyte and impurities inside the recovery tank 13 in real time and displays the data on its surface display. Simultaneously, the battery 16 in the battery box 17 provides power for the equipment's operation. When the battery 16 is low on power, it can be charged through the charging port 15. The PLC controller 18 is operated again to control the first electric telescopic rod 8 to raise the placement plate 3 and the pipes on it. The operator removes the polished pipe from the placement plate 3, completing one internal wall electrolytic polishing operation.
