Description

Technical Field

[0001] The present invention relates to the field of alloy wire passivation, and particularly to a passivation treatment device for corrosion-resistant alloy wires. Background Art

[0002] Electrolytic passivation, also known as electrochemical passivation, is a technique that forms a dense and firm oxide or compound film on the metal surface through an electrochemical reaction to slow down or almost prevent the electrochemical dissolution phenomenon of the anode metal, thereby improving the corrosion resistance of the metal. During operation, the metal serves as the anode, and the electrode plate inside the passivation tank serves as the cathode, and thus the electrolytic passivation operation can be carried out. In the prior art, the electrolytic passivation of alloy wires is generally carried out in sections. During specific operations, some auxiliary means, such as agitation or other liquid flow methods, are adopted to ensure the stability of the concentration and temperature of the passivation solution, so as to ensure the actual passivation effect. However, in actual use, we found that the agitation part or other liquid flow methods in the current passivation device are always running. When the passivation solution moves, it is easy to damage the passivation film being formed, resulting in poor passivation effect, and it is also easy to generate bubbles. When the alloy wire is in the passivation state, the appearance of these bubbles will also cause defects on the surface of the passivation layer. Therefore, how to solve the above problems needs to be considered. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. Equipped with a liquid flow mechanism, after the drive motor is started, a series of one-way liquid flows will be triggered: from the right space of the passivation box, through the filter cylinder, into the right space of the first piston cylinder, and finally flow to the left space of the passivation box. This specific direction of liquid flow helps to maintain the temperature and concentration of the passivation liquid within an ideal range, thereby ensuring that the next time the alloy wire body is passivated, a high-quality passivation effect can be obtained.

[0013] 2. The unidirectional flow of liquid will also purify the passivation liquid, collect the impurities in it, prevent these impurities from affecting the passivation operation, and ensure that the passivation liquid always remains in a high-quality state.

[0014] 3. During the operation, the flowing part of the liquid and the moving part of the alloy wire are coordinated and linked. Specifically, when the alloy wire is in the passivation treatment stage, that is, when it is stationary, the passivation liquid will also remain stationary accordingly to ensure that the passivation process of the alloy wire will not be interfered with. Once the current section of the alloy wire has completed the passivation treatment and the next section of the alloy wire is about to enter the passivation liquid, the liquid will begin to flow. This design is intended to maintain the optimal concentration and temperature conditions of the passivation liquid, while ensuring that the passivation effect of the alloy wire will not be adversely affected during the flow of the liquid.

[0015] 4. When the drive motor is operating, gas is stored. When the drive motor stops moving, the impact force generated by the rapid release of high-pressure gas is used to push the cross plate into the passivation tank, effectively slowing down the continuous movement of the passivation liquid due to inertia, thereby maintaining the stability of the passivation liquid, avoiding the adverse effects of excessive movement of the passivation liquid on the passivation effect, and ensuring the stability of the passivation process.

[0016] In summary, in practical applications, the device can ensure that the concentration and temperature of the passivation liquid are maintained at a uniform and appropriate level. At the same time, it can ensure that during the process of liquid flow, it will not have an adverse impact on the passivation effect of the alloy wire, and can effectively remove impurities in the passivation liquid to ensure the quality of the passivation liquid.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Reference Figures 1-7 , a passivation treatment device for corrosion-resistant alloy wire, comprising a passivation box 1. A plurality of guiding components 7 are arranged in the passivation box 1. Each guiding component 7 is composed of a rotating shaft and a guiding wheel fixedly connected to the middle of the rotating shaft. An alloy wire body 10 is wound around the plurality of guiding wheels together. One of the guiding components 7 is made of a conductive material, which can be industrial titanium, and it has good stability. The rotating shaft part thereof is connected to the positive electrode of an external storage battery through an electrical rotary joint. An electrode plate (not shown) is also installed at the bottom inside the passivation box 1 for electrically connecting to the negative electrode of the external storage battery. The storage battery is provided with an electric control switch. When the electric control switch is closed, an electrolytic reaction can be carried out. In addition, an electric heating plate (not shown) is installed inside the passivation box 1 to ensure that the whole is at the temperature required for passivation. The front and rear ends of each rotating shaft are rotatably connected to the front and rear inner walls of the passivation box 1.

[0021] As an implementation mode of the present invention, it further includes a liquid flow mechanism. The liquid flow mechanism includes a rotating shaft 18 rotatably connected to the front side of the passivation box 1. A pulley 2 is installed on the rotating shaft 18. Further, the passivation box 1 is the previous process of the alloy wire winding part. After the alloy wire is passivated and then passes through a rinsing and drying box, it is finally wound.

The right side space of the first piston cylinder 4 communicates with a first one-way pipe 24, and the right side space of the first piston cylinder 4 communicates with a second one-way pipe 17. Hollow plates 9 are installed on the inner walls of the left and right sides of the passivation tank 1, and a plurality of holes 11 are formed on the opposite sides of the two hollow plates 9. A filter cylinder 6 is installed on the right side of the passivation tank 1, and the left side space of the filter cylinder 6 communicates with the inside of the right hollow plate 9.

By this means, the passivation liquid can be filtered to remove impurities in the passivation liquid. The other end of the second one-way pipe 17 communicates with the inside of the left hollow plate 9.

[0024] As an implementation manner of the present invention, a second piston cylinder 19 is fixedly connected to the right inner wall of the first piston cylinder 4. A second piston block 21 capable of sliding left and right is arranged in the second piston cylinder 19. The second piston block 21 is fixedly connected to the first piston block 33 through a connecting rod 20. A fourth piston cylinder 14 is fixedly connected to the rear side of the passivation tank 1. The front side space of the fourth piston cylinder 14 communicates with the outside through a through port (not shown). A fourth piston block 31 capable of sliding back and forth is arranged in the fourth piston cylinder 14. The front side of the fourth piston block 31 is elastically connected to the front inner wall of the fourth piston cylinder 14 through a second spring 32. The right side space of the second piston cylinder 19 communicates with the outside through a one-way port 22. The right side space of the second piston cylinder 19 communicates with the rear side space of the fourth piston cylinder 14 through a third one-way pipe 23. Check valves are installed inside both the one-way port 22 and the third one-way pipe 23. The flow direction of the check valve of the one-way port 22 is that the outside enters the inside of the second piston cylinder 19 unidirectionally, and the flow direction of the check valve of the third one-way pipe 23 is that the right side space of the second piston cylinder 19 enters the rear side space of the fourth piston cylinder 14 unidirectionally.

[0025] As an implementation manner of the present invention, it further includes a flow blocking mechanism. The flow blocking mechanism is used to reduce the fluidity of the liquid. The flow blocking mechanism includes a plurality of rectangular blocks 12 fixedly connected to the rear side of the passivation tank 1. A cross groove 25 is formed on the front side of each rectangular block 12. The front side of the cross groove 25 communicates with the inside of the passivation tank 1. A cross plate 26 that can slide back and forth is arranged in the cross groove 25. The cross plate 26 is a hollow plastic plate with a relatively light overall weight. A third piston cylinder 13 is fixedly connected to the rear side of each rectangular block 12. A third piston block 28 that can slide back and forth is arranged in each third piston cylinder 13. The rear end of each third piston block 28 is elastically connected to the rear inner wall of the third piston cylinder 13 through a first spring 27. A piston rod 29 is fixedly connected to the front side of each third piston block 28. The other end of each piston rod 29 is fixedly connected to the rear end of the corresponding cross plate 26. The spring constant of the second spring 32 is greater than that of the first spring 27, and the spring constants of both the first spring 27 and the second spring 32 are relatively large. The rear space of the fourth piston cylinder 14 communicates with the main pipeline 15. A normally open solenoid valve is installed in the main pipeline 15. The other end of the main pipeline 15 communicates with the rear spaces of a plurality of third piston cylinders 13 through a plurality of branch pipelines 16. The rear spaces of the plurality of third piston cylinders 13 communicate with the outside through small holes 30. The aperture of the small holes 30 is one-fourth of the pipe diameter of the branch pipelines 16.

[0026] When the present invention is in use, first turn on the manual switch of the storage battery. At this time, the passivation tank 1 is filled with passivation liquid. Start the internal electric heating plate. After the passivation liquid reaches an appropriate temperature, turn on the control switch of the storage battery. After the control switch of the storage battery is turned on, it will energize the electrode plate and the conductive guiding component 7. At this time, the alloy wire body 10 part located in the passivation liquid is the anode, and the electrode plate is the cathode, so as to carry out an electrolytic reaction for passivation. After the passivation of this part of the alloy wire body 10 is completed (the passivation time is generally about two minutes), start the driving motor for winding, so that the part of the alloy wire body 10 located in the passivation liquid moves to the subsequent process, and the part of the alloy wire body 10 located in the previous process is displaced into the passivation liquid. During this process, through the transmission of the pulley 2, the rotating shaft 18 can be rotated. The rotation of the rotating shaft 18 will cause the first piston block 33 to move left and right reciprocally through the movable rod 5. By using the functions of the first one-way pipe 24, the second one-way pipe 17 and the internal one-way valve, a one-way liquid flow in the right space of the passivation tank 1, the filter cylinder 6, the right space of the first piston cylinder 4 and the left space of the passivation tank 1 can be generated. This liquid flow can keep the temperature and concentration of the passivation liquid in a better and more uniform state, ensuring the passivation quality when the alloy wire body 10 is passivated next time. The above-mentioned one-way liquid flow will also purify the passivation liquid, so that the impurities therein (such as organic impurities decomposed by the catalyst) are collected, avoiding the influence of these impurities on the passivation operation. The left and right reciprocating motion of the first piston block 33 will also allow the second piston block 21 to reciprocate left and right through the connecting rod 20, and cooperate with the one-way port 22 and the one-way valve inside the third one-way tube 23 to generate one-way gas flow between the outside, the second piston cylinder 19 and the fourth piston cylinder 14. Since the normally open solenoid valve in the main pipeline 15 is in the energized closed state at this time, the gas will gather in the space behind the fourth piston cylinder 14, and push the fourth piston block 31 forward, and stretch the second spring 32. When the drive motor is turned off and stops moving, the partial replacement of the alloy wire body 10 in the passivation liquid is completed. At this time, the pulley 2 stops moving, the liquid flow mechanism also stops running, and the battery is turned on for electrolysis. At the same time, the normally open solenoid valve is turned on and off, and the high-pressure gas in the fourth piston cylinder 14 will be quickly released through the main pipeline 15 and multiple branches. The pipe 16 enters the rear space of the plurality of third piston cylinders 13. Since the space of the pore 30 is small, the gas release speed is slow. Therefore, after a large amount of gas is gathered in the rear space of the plurality of third piston cylinders 13, it will push the plurality of third piston blocks 28 forward, and use the piston rod 29 to drive the plurality of cross plates 26 forward, so that the plurality of cross plates 26 are moved to the inside of the passivation box 1. When the driving motor stops moving, although the liquid flow mechanism stops running, since the liquid has inertia, its inertia will still cause the passivation liquid to move in the passivation box 1 for a period of time (10-20 seconds). After the plurality of cross plates 26 are extended, the liquid movement in the passivation box 1 is greatly hindered, which can greatly reduce the speed and overall time of the liquid flowing due to inertia, thereby avoiding its influence on passivation and ensuring the actual passivation quality to the greatest extent. When the gas in the fourth piston cylinder 14 is completely released, the third piston block 28, the piston rod 29 and the cross plate 26 will eventually move backwards under the elastic action of the first spring 27, which is convenient for the next use and avoids interference with the subsequent liquid flow.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
