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 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, enabling electrolytic passivation operation.

[0003] In the prior art, the electrolytic passivation of alloy wires is generally carried out in segments. 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, thereby ensuring the actual passivation effect. However, in actual use, it is 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 forming passivation film, 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

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a passivation treatment device for corrosion-resistant alloy wires. When the device is in use, the liquid flow part is linked with the alloy wire movement part, so that when the alloy wire is undergoing passivation operation, the liquid does not move, and after the alloy wire completes passivation, during the period when the next section of alloy wire enters the passivation solution, the liquid moves to ensure that the concentration and temperature of the passivation solution are in a uniform state.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An apparatus for passivating a corrosion-resistant alloy wire includes a passivation tank. Inside the passivation tank, a plurality of guiding components are provided. Each guiding component consists of a rotating shaft and a guiding wheel fixedly connected to the middle of the rotating shaft.

[0007] Preferably, one-way valves are installed inside both the first one-way pipe and the second one-way pipe.

The flow direction of the one-way valve inside the second one-way pipe is that the right side space of the first piston cylinder enters the left hollow plate unidirectionally.

[0008] Preferably, a second piston cylinder is fixedly connected to the right inner wall of the first piston cylinder. A second piston block that can slide left and right is arranged inside the second piston cylinder. The second piston block and the first piston block are fixedly connected by a connecting rod.

[0009] Preferably, a fourth piston cylinder is fixedly connected to the rear side of the passivation tank. A fourth piston block that can slide back and forth is arranged inside the fourth piston cylinder. The front side of the fourth piston block is elastically connected to the front inner wall of the fourth piston cylinder by a second spring. The right side space of the second piston cylinder is communicated with the outside through a one-way port. The right side space of the second piston cylinder is communicated with the rear side space of the fourth piston cylinder through a third one-way pipe.

[0010] Preferably, one-way valves are installed inside both the one-way port and the third one-way pipe. The flow direction of the one-way valve of the one-way port is that the outside enters the inside of the second piston cylinder unidirectionally. The flow direction of the one-way valve of the third one-way pipe is that the right side space of the second piston cylinder enters the rear side space of the fourth piston cylinder unidirectionally.

[0011] Preferably, one of the guiding components is made of a conductive material.

[0012] Preferably, the flow blocking mechanism includes a plurality of rectangular blocks fixedly connected to the rear side of the passivation box, a cross slot is provided on the front side of each rectangular block, the front side of the cross slot is connected to the interior of the passivation box, and a cross plate that can slide back and forth is provided in the cross slot.

[0013] Preferably, the rear side of each of the rectangular blocks is fixedly connected to a third piston cylinder, and each of the third piston cylinders is provided with a third piston block that can slide back and forth, and the rear end of each of the third piston blocks is elastically connected to the rear inner wall of the third piston cylinder through a first spring, and the front side of each of the third piston blocks is fixedly connected to a piston rod, and the other end of each of the piston rods is fixedly connected to the rear end of the corresponding cross plate, the spring coefficient of the second spring is greater than the spring coefficient of the first spring, and the rear space of the fourth piston cylinder is connected to a main pipeline, and a normally open solenoid valve is installed in the main pipeline, and the other end of the main pipeline is connected to the rear spaces of multiple third piston cylinders through multiple branch pipelines, and the rear spaces of multiple third piston cylinders are connected to the outside world through fine holes, and the aperture of the fine holes is one quarter of the diameter of the branch pipeline.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Equipped with a liquid flow mechanism, when the drive motor is started, it will trigger a series of unidirectional liquid flows: 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 passivation of the alloy wire body can achieve a high-quality passivation effect.

[0016] 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 is always maintained in a high-quality state.

[0017] 3. During operation, the flowing portion of the liquid is coordinated with the moving portion of the alloy wire. Specifically, when the alloy wire is in the passivation treatment stage, that is, when it is stationary, the passivation liquid will also remain stationary to ensure that it does not interfere with the passivation process of the alloy wire. Once the current section of alloy wire has completed the passivation treatment and the next section of 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 flow of the liquid will not adversely affect the passivation effect of the alloy wire.

[0018] 4. When the driving motor is working, gas is stored. When the driving 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.

[0019] In summary, in practical applications, this 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 Embodiments

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Refer to Figures 1-7 , a passivation treatment device for a corrosion-resistant alloy wire, including 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 main 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. In addition, an electrode plate (not shown) is 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 electrolysis 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.

In this solution, a pulley 2 is also installed on the driving motor of the winding part. The two pulleys 2 are connected by a transmission belt. It should be noted that the driving motor, the normally open solenoid valve, and the electric control switch of the storage battery for electrolysis are controlled by a PLC to realize the synchronous opening and closing of the driving motor and the normally open solenoid valve. When the driving motor is turned off, the electric control switch of the storage battery is closed. When the driving motor is turned on, the electric control switch of the storage battery is turned off. Further, the storage battery is also provided with a manual switch for controlling the on and off of the power.

The left side of the first piston block 33 is rotatably connected to the movable rod 5, and the left end of the movable rod 5 is rotatably connected to the front eccentric position of the circular rotating plate 3. The right side space of the first piston cylinder 4 is connected to the first one-way tube 24, and the right side space of the first piston cylinder 4 is connected to the second one-way tube 17. Hollow plates 9 are installed on the left and right inner walls of the passivation box 1, and multiple holes 11 are opened on the opposite sides of the two hollow plates 9. A filter cartridge 6 is installed on the right side of the passivation box 1. The left space of the filter cartridge 6 is connected to the inside of the hollow plate 9 on the right, and the other end of the first one-way tube 24 is connected to the right side space of the filter cartridge 6. The filter cartridge 6 is a cylinder with a filter element installed inside. In this way, the passivation liquid can be filtered to remove impurities in the passivation liquid. The other end of the second one-way tube 17 is connected to the inside of the hollow plate 9 on the left.

[0032] As an embodiment of the present invention, a one-way valve is installed inside the first one-way tube 24 and the second one-way tube 17. The one-way valve inside the first one-way tube 24 flows in a one-way direction from the right side space of the filter cylinder 6 to the right side space of the first piston cylinder 4, and the one-way valve inside the second one-way tube 17 flows in a one-way direction from the right side space of the first piston cylinder 4 to the left hollow plate 9.

[0033] As an embodiment of the present invention, a second piston cylinder 19 is fixedly connected to the right inner wall of the first piston cylinder 4, and a second piston block 21 that can slide left and right is provided in the second piston cylinder 19. The second piston block 21 is fixedly connected to the first piston block 33 by a connecting rod 20, and the rear side of the passivation box 1 is fixedly connected to the fourth piston cylinder 14. The front space of the fourth piston cylinder 14 is connected to the outside world through a through port not shown in the figure, and a fourth piston block 31 that can slide back and forth is provided in the fourth piston cylinder 14. The front side of the fourth piston block 31 is connected to the second spring The spring 32 is elastically connected to the front inner wall of the fourth piston cylinder 14, and the right side space of the second piston cylinder 19 is connected to the outside world through the one-way port 22. The right side space of the second piston cylinder 19 is connected to the rear side space of the fourth piston cylinder 14 through the third one-way tube 23. One-way valves are installed inside the one-way port 22 and the third one-way tube 23. The one-way valve of the one-way port 22 flows in a one-way direction from the outside world to the inside of the second piston cylinder 19, and the one-way valve of the third one-way tube 23 flows in a one-way direction from the right side space of the second piston cylinder 19 to the rear side space of the fourth piston cylinder 14.

[0034] As an implementation mode 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 is communicated 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 stiffness coefficient of the second spring 32 is greater than that of the first spring 27, and the stiffness coefficients of both the first spring 27 and the second spring 32 are relatively large. The rear space of the fourth piston cylinder 14 is communicated 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 is communicated 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 are all communicated with the outside through fine holes 30. The aperture of the fine holes 30 is one-fourth of the pipe diameter of the branch pipelines 16.

[0035] 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 a suitable temperature, turn on the control switch of the storage battery. After the control switch of the storage battery is turned on, it will make the electrode plate and the conductive guiding component 7 energized. At this time, the alloy wire body 10 part located in the passivation liquid is the anode, and the electrode plate is the negative electrode, so as to carry out an electrolytic reaction for passivation.

[0036] 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. In this process, through the transmission of the pulley 2, the rotating shaft 18 can be rotated. The rotation of the rotating shaft 18 will make the first piston block 33 perform left and right reciprocating movements 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.

[0037] The above-mentioned unidirectional liquid flow will also purify the passivation liquid, enabling impurities therein (such as organic impurities decomposed from the catalyst) to be collected, thus preventing these impurities from affecting the passivation operation;

[0038] The reciprocating movement of the first piston block 33 to the left and right will also cause the second piston block 21 to reciprocate to the left and right through the connecting rod 20. In cooperation with the check valves inside the one-way port 22 and the third one-way pipe 23, a unidirectional gas flow among the outside, the second piston cylinder 19 and the fourth piston cylinder 14 can be generated. Since the normally open solenoid valve in the main pipeline 15 is in the power-on and closed state at this time, the gas will accumulate in the rear space of the fourth piston cylinder 14 and push the fourth piston block 31 forward, and stretch the second spring 32. When the driving motor stops moving, that is, a part of the alloy wire body 10 located in the passivation liquid is replaced once. At this time, the pulley 2 stops moving, and the liquid flow mechanism also stops operating. Meanwhile, the storage battery is conducted for electrolysis. At the same time, the normally open solenoid valve is conducted for power on and off, and the high-pressure gas in the fourth piston cylinder 14 will be quickly released and enter the rear spaces of multiple third piston cylinders 13 through the main pipeline 15 and multiple branch pipelines 16. Since the space of the fine hole 30 is small, the gas release speed is slow. Therefore, after a large amount of gas accumulates in the rear spaces of multiple third piston cylinders 13, it will push multiple third piston blocks 28 forward, and use the piston rod 29 to drive multiple cross plates 26 forward, so that multiple cross plates 26 move into the passivation tank 1. When the driving motor stops moving, although the liquid flow mechanism stops operating, due to the inertia of the liquid, its inertia effect will still cause the passivation liquid to move in the passivation tank 1 for a period of time (10 - 20 seconds). After multiple cross plates 26 extend, the movement of the liquid inside the passivation tank 1 encounters a greater movement resistance, which can greatly reduce the speed and overall time of the liquid flowing due to inertia, preventing it from affecting the passivation and ensuring the actual passivation quality to the greatest extent;

[0039] When the gas in the fourth piston cylinder 14 is completely released, finally, under the elastic action of the first spring 27, the third piston block 28, the piston rod 29 and the cross plate 26 will all move backward, facilitating the next use and preventing interference with the subsequent required liquid flow.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
