Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to anodizing production line equipment for mechanical parts processing. Background Technology

[0002] Anodizing production line equipment is a production equipment specifically used for anodizing metal materials, especially aluminum alloys. Anodizing is a process that forms a dense and corrosion-resistant oxide film on the metal surface through an electrochemical reaction.

[0003] In the traditional anodizing process, the electrolyte is easily contaminated by impurities, oxides and other reaction products on the metal surface. This can lead to changes in the conductivity of the electrolyte, affecting the stability of the current, and consequently causing uneven thickness and quality of the oxide film. Contaminants can also cause defects, inconsistent colors or reduced corrosion resistance on the oxide film surface, seriously affecting the performance and quality of metal parts. Therefore, electrolyte contamination directly affects the efficiency of the oxidation process and the final effect of the oxide film. Utility Model Content

[0004] The technical problem this invention aims to solve is that in the traditional anodizing process, the electrolyte is easily contaminated by impurities, oxides, and other reaction products on the metal surface. This leads to changes in the conductivity of the electrolyte, affects the stability of the current, and consequently results in uneven thickness and quality of the oxide film. Contaminants may also cause defects, inconsistent colors, or reduced corrosion resistance on the oxide film surface, seriously affecting the performance and quality of metal parts. Therefore, electrolyte contamination directly affects the efficiency of the oxidation process and the final effect of the oxide film.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an anodizing production line equipment for machining mechanical parts, including an oxidation tank, and a circulating filtration device is provided on one side of the oxidation tank. The circulating filtration device can use a circulating pump to draw the electrolyte in the oxidation tank into the filter box for filtration treatment through the first guide pipe and the second guide pipe, and then transport it back to the oxidation tank through the third guide pipe, thereby achieving the effect of filtering and maintaining the electrolyte.

[0006] Preferably, the circulating filtration device includes a circulating pump, a first guide pipe and a second guide pipe, wherein one end of the first guide pipe and the second guide pipe are respectively fixedly installed at the inlet and outlet of the circulating pump; a filter box, wherein one side of the filter box is fixedly installed on one side of the oxidation tank, and the two ends of the first guide pipe and the second guide pipe are respectively installed through one side of the oxidation tank and the top of the filter box; a third guide pipe, wherein the two ends of the third guide pipe are respectively installed through one side of the filter box and one side of the oxidation tank; and a filtration mechanism, wherein the filtration mechanism is disposed on the inner wall of the filter box for filtering and intercepting the electrolyte entering the filter box.

[0007] The aforementioned components achieve the following effects: When using an oxidation tank to oxidize mechanical parts, an electrolyte is placed in the oxidation tank, followed by the mechanical parts. The internal power supply of the oxidation tank is then activated to provide direct current, with the metal parts acting as the anode. The current in the electrolyte flows through the electrolytic cell. The positive terminal of the power supply is connected to the metal workpiece, and the negative terminal is connected to the cathode in the electrolytic cell. The current flowing through the electrolyte causes an oxidation reaction on the metal surface, forming a dense alumina film, thus completing the oxidation electroplating process. During electroplating or when not in use, a circulation pump can be activated to draw the electrolyte from the oxidation tank from the first guide pipe into the second guide pipe, and then into the filter box. After filtration, the electrolyte falls to the bottom of the filter box and is discharged back into the oxidation tank through the third guide pipe for continued electroplating. This effectively removes impurities and debris from the electrolyte, enabling continuous recycling of the electrolyte, maintaining its cleanliness and stability, reducing the negative impact of contamination on the quality of the oxide film, and thus improving the oxidation effect, efficiency, and processing quality.

[0008] Preferably, the filtration mechanism includes a square tube frame, one end of which is inserted into the inner wall of the filter box, and a limiting mechanism is provided between one side of the square tube frame and both sides of the filter box; a filter screen, one end of which is slidably installed in the inner wall of the square tube frame; a plurality of springs, the two ends of which are respectively fixedly installed on one side of the filter screen and one side of the square tube frame; a striking rod, one end of which is installed through the inner wall of the filter box and the other end of which abuts against one side of the filter screen; and a motor, one side of which is fixedly installed on one side of the filter box, and the output end is fixedly installed on one side of the striking rod by means of a coupling.

[0009] The effects achieved by the above components are as follows: By setting up a filtration mechanism, when the electrolyte is being filtered in a circulating manner, the square tube frame can be inserted into the inner wall of the filter box first, and then fixed and limited by a limiting mechanism. After the electrolyte is drawn into the filter box through the second guide tube, it will fall onto the filter screen for filtration. At the same time, the motor is started to drive the striking rod to rotate, causing the eccentric wheel on the striking rod to rotate and abut against the filter screen, moving it upward in the inner wall of the square tube frame. This causes the spring to stretch. Then, when one end of the eccentric wheel is completely removed from the filter screen, the filter screen can quickly return to its downward position and vibrate under the reset action of the spring. This makes the filter less prone to clogging during filtration and interception, improves the filtration effect, effectively removes impurities and debris from the electrolyte, realizes the continuous circulation of the electrolyte, keeps the electrolyte clean and stable, reduces the negative impact of pollution on the quality of the oxide film, and thus improves the oxidation effect, efficiency, and processing quality.

[0010] Preferably, the longitudinal section of the filter screen is trapezoidal, and the size of the end of the filter screen near the second guide tube is larger than the size of the other end.

[0011] The effect achieved by the above components is that by setting the filter screen in a trapezoidal shape, the contact area between the electrolyte and the filter screen can be increased. At the same time, the impurities filtered out can be retained in the middle position, while the other surfaces can still be filtered, thus improving the filtration effect.

[0012] Preferably, the filtering mechanism further includes several telescopic sleeves, wherein the inner wall of the telescopic sleeves is sleeved on the outer surface of the spring, and its two ends are respectively fixedly installed on one side of the filter screen and one side of the square tube frame.

[0013] The effect achieved by the above components is that by setting a telescopic sleeve, the spring can be covered and protected, so that the electroplating solution will not easily fall onto the spring after passing through the filter screen, thus avoiding affecting the use of the spring.

[0014] Preferably, a circular roller is rotatably mounted on the inner wall of one end of the deflection wheel on the striking rod.

[0015] The effect achieved by the above components is that by setting up the circular roller, the contact friction between one end of the eccentric wheel of the striking rod and the filter screen can be reduced, making it easier to push and improving the service life of both.

[0016] Preferably, the limiting mechanism includes two locking blocks, one side of which is fixedly installed on one side of the filter box; and two elastic locking blocks, one side of which is fixedly installed on one side of the square tube frame, and one end of which is inserted into the inner wall of the locking block.

[0017] The effect achieved by the above components is that after the square tube frame is inserted into the inner wall of the filter box, the elastic blocks on both sides can be locked into the inner wall of the locking block to limit their position. In this way, the square tube frame and the filter screen can be fixed to the inner wall of the filter box for use. Similarly, the reverse operation can be performed to disassemble them for easy replacement and cleaning.

[0018] Preferably, a sealing ring block is fixedly installed on one side of the square tube frame, and the outer surface dimension of the sealing ring block is larger than the inner wall of one side of the filter box.

[0019] The effect achieved by the above components is as follows: by setting the sealing ring block, the gap between the connection between one side of the square tube frame and the filter box can be sealed and blocked, preventing the electrolyte in the filter box from overflowing from the gap. This not only maintains the stability of the electrolyte and reduces waste, but also avoids electrolyte leakage from causing pollution to the surrounding environment.

[0020] The beneficial effects of this utility model are:

[0021] By setting up a circulating filtration device, during the electroplating process or when not in use, the circulating pump can be started to draw the electrolyte in the oxidation tank from the first guide pipe into the second guide pipe, and then into the filter box. After being filtered by the filtration mechanism, the electrolyte falls to the bottom of the filter box and is discharged back into the oxidation tank through the third guide pipe for continued electroplating. This effectively removes impurities and debris from the electrolyte, enabling continuous recycling of the electrolyte, maintaining its cleanliness and stability, reducing the negative impact of pollution on the quality of the oxide film, and thus improving the oxidation effect, efficiency, and processing quality.

[0032] Figure 1-6 The anodizing production line equipment for machining mechanical parts shown includes an oxidation tank 1. A circulating filter device 2 is provided on one side of the oxidation tank 1. The circulating filter device 2 can use a circulating pump 21 to pump the electrolyte in the oxidation tank 1 into a filter box 24 for filtration through a first guide pipe 22 and a second guide pipe 23. Then, the electrolyte is transported back to the oxidation tank 1 through a third guide pipe 25, thereby achieving the effect of filtering and maintaining the electrolyte.

[0033] It should be noted that oxidation pool 1 is a mature oxidation technology and equipment in the existing technology, and its internal structure, connection method and principle will not be described further.

[0034] Figure 1-6The circulating filtration device 2 shown includes a circulating pump 21 (model TP 32-100), a first guide pipe 22 and a second guide pipe 23, wherein one end of the first guide pipe 22 and the second guide pipe 23 are respectively fixedly installed at the inlet and outlet of the circulating pump 21; a filter box 24, wherein one side of the filter box 24 is fixedly installed on one side of the oxidation tank 1, and the two ends of the first guide pipe 22 and the second guide pipe 23 are respectively installed through one side of the oxidation tank 1 and the top of the filter box 24; a third guide pipe 25, wherein the two ends of the third guide pipe 25 are respectively installed through one side of the filter box 24 and one side of the oxidation tank 1; and a filtration mechanism 27, wherein the filtration mechanism 27 is disposed on the inner wall of the filter box 24 and is used to filter and intercept the electrolyte entering the filter box 24. When using oxidation tank 1 to perform oxidation processing on mechanical parts, an electrolyte is placed in oxidation tank 1, and then the mechanical parts are placed into the electrolyte in oxidation tank 1. The power supply inside oxidation tank 1 is then activated to provide direct current, with the metal parts acting as the anode. The current in the electrolyte flows through the electrolytic cell. The positive terminal of the power supply is connected to the metal workpiece, and the negative terminal is connected to the cathode in the electrolytic cell. When an electric current passes through the electrolyte, an oxidation reaction occurs on the metal surface, forming a dense aluminum oxide film. This completes the oxidation electroplating process. During the electroplating process or when not in use, the circulation pump 21 can be started to draw the electrolyte in the oxidation tank 1 from the first guide pipe 22 into the second guide pipe 23, and then into the filter box 24. After being filtered by the filter mechanism 27, the electrolyte falls to the bottom of the filter box 24 and is discharged back into the oxidation tank 1 through the third guide pipe 25 for continued electroplating. This effectively removes impurities and debris from the electrolyte, enabling continuous recycling of the electrolyte, maintaining its cleanliness and stability, reducing the negative impact of pollution on the quality of the oxide film, and thus improving the oxidation effect, efficiency, and processing quality.

[0035] It should be noted that the circulating pump 21 is a mature circulating technology and equipment in the existing technology, and its internal structure, connection method and principle will not be described further.

[0036] Figure 1-6The filter mechanism 27 shown includes a square tube frame 271, one end of which is inserted into the inner wall of the filter box 24, and a limit mechanism 26 is provided between one side of the square tube frame 271 and both sides of the filter box 24; a filter screen 272, one end of which is slidably installed in the inner wall of the square tube frame 271; several springs 273, the two ends of which are respectively fixedly installed on one side of the filter screen 272 and one side of the square tube frame 271; a striking rod 275, one end of which is installed through the inner wall of the filter box 24, and the other end abuts against one side of the filter screen 272; and a motor 276, one side of which is fixedly installed on one side of the filter box 24, and the output end is fixedly installed on one side of the striking rod 275 by means of a coupling. By setting up the filtration mechanism 27, when the electrolyte is being filtered in a circulating manner, the square tube frame 271 can be inserted into the inner wall of the filter box 24 and then fixed in place by the limiting mechanism 26. After the electrolyte is drawn into the filter box 24 by the second guide tube 23, it will fall onto the filter screen 272 for filtration. At the same time, the motor 276 is started to drive the striking rod 275 to rotate, causing the eccentric wheel on the striking rod 275 to rotate and abut against the filter screen 272, moving it upward in the inner wall of the square tube frame 271. This causes the spring 273 to be stretched. Then, when one end of the eccentric wheel is completely removed from the filter screen 272, the filter screen 272 can be quickly reset downward under the reset action of the spring 273, causing it to vibrate. This makes the filter less prone to clogging during filtration and interception, improving the filtration effect, effectively removing impurities and debris from the electrolyte, realizing the continuous circulation of the electrolyte, maintaining the cleanliness and stability of the electrolyte, reducing the negative impact of pollution on the quality of the oxide film, and thus improving the oxidation effect, efficiency, and processing quality. The longitudinal section of the filter screen 272 is trapezoidal, with the end of the filter screen 272 closest to the second guide tube 23 being larger than the other end. By setting the filter screen 272 to a trapezoidal shape, the contact area between the electrolyte and the filter screen 272 can be increased. At the same time, it can also retain the impurities filtered out in the middle position, while the other surfaces can still be filtered, thus improving the filtration effect.

[0037] Figure 1-6 The filter mechanism 27 shown also includes several telescopic sleeves 274, the inner walls of which are fitted onto the outer surface of the spring 273, and both ends are fixedly mounted on one side of the filter screen 272 and one side of the square tube frame 271, respectively. By providing the telescopic sleeves 274, the spring 273 can be covered and protected, preventing the electroplating solution from easily dripping onto the spring 273 after passing through the filter screen 272, thus avoiding affecting the use of the spring 273. A circular roller 277 is rotatably mounted on the inner wall of one end of the deflection wheel on the striking rod 275. By providing the circular roller 277, the contact friction between the eccentric wheel end of the striking rod 275 and the filter screen 272 can be reduced, making it easier to push and improving the service life of both.

[0038] Figure 1-6 The limiting mechanism 26 shown includes two locking blocks 261, one side of which is fixedly installed on one side of the filter box 24; and two elastic locking blocks 262, one side of which is fixedly installed on one side of the square tube frame 271, with one end inserted into the inner wall of the locking block 261. After the square tube frame 271 is inserted into the inner wall of the filter box 24, the elastic locking blocks 262 on both sides can be locked into the inner wall of the locking block 261 to limit its movement. This allows the square tube frame 271 and the filter screen 272 to be fixed in place within the filter box 24. Similarly, the reverse operation allows for disassembly for easy replacement and cleaning. A sealing ring block 263 is fixedly installed on one side of the square tube frame 271, and the outer surface dimension of the sealing ring block 263 is larger than the inner wall of one side of the filter box 24. By setting the sealing ring block 263, the gap at the connection between one side of the square tube frame 271 and the filter box 24 can be sealed and blocked, preventing the electrolyte in the filter box 24 from overflowing from the gap. This not only maintains the stability of the electrolyte and reduces waste, but also avoids electrolyte leakage from causing pollution to the surrounding environment.

[0039] Working principle: When using oxidation tank 1 to oxidize mechanical parts, first insert the square tube frame 271 into the inner wall of the filter box 24, so that the elastic blocks 262 on both sides are locked into the inner wall of the locking block 261, thereby fixing the square tube frame 271 and the filter screen 272 in the inner wall of the filter box 24. Then, the electrolyte is put into oxidation tank 1, and then the mechanical parts are put into the electrolyte in oxidation tank 1. Then, the power supply device inside oxidation tank 1 is activated to provide DC current to energize it. The metal parts act as the anode, and the current in the electrolyte flows through the electrolytic cell. The positive terminal of the power supply is connected to the metal workpiece, and the negative terminal is connected to the cathode in the electrolytic cell. An electric current passes through the electrolyte, causing an oxidation reaction on the metal surface, forming a dense aluminum oxide film. This completes the oxidation electroplating process. During electroplating or when not in use, the circulation pump 21 can be started to draw the electrolyte from the oxidation tank 1 from the first guide pipe 22 into the second guide pipe 23, and then into the filter box 24, where it falls onto the filter screen 272 for filtration. Simultaneously, the motor 276 is started to drive the striking rod 275 to rotate, causing the eccentric wheel on the striking rod 275 to rotate and abut against the filter screen 272 against the inner wall of the square tube frame 271. The upward movement causes the spring 273 to stretch. Then, when one end of the eccentric wheel is completely removed from the filter screen 272, the filter screen 272 can quickly return to its downward position and vibrate under the restoring action of the spring 273. This makes the filter less prone to clogging during filtration and interception, improves the filtration effect, effectively removes impurities and debris from the electrolyte, realizes the continuous recycling of the electrolyte, keeps the electrolyte clean and stable, reduces the negative impact of pollution on the quality of the oxide film, and thus improves the oxidation effect, efficiency and processing quality.
