Description

Technical Field

[0001] This invention relates to the field of metal surface treatment technology, and in particular to an integrated passivation process for corrosion-resistant alloy wire coils. Background Technology

[0002] Corrosion-resistant alloy wire is an important raw material for aerospace equipment. It is made of corrosion-resistant alloy materials and requires passivation treatment after drawing and forming. A passivation film is formed on the outside of the corrosion-resistant alloy wire to further enhance its overall corrosion resistance.

[0003] During the passivation process of corrosion-resistant alloy wire coils, the coils can be loosely wound into single strands and oriented through a predetermined passivation device. This ensures comprehensive and efficient passivation of the outer surface of the alloy wire. However, this operation is costly, requires specialized unwinding and guiding equipment, and has low processing efficiency. For corrosion-resistant alloy wire coils with lower requirements, the entire coil is directly immersed in the passivation solution. The diffusion effect of the liquid is used to passivate various parts of the alloy wire surface. However, the passivation solution has limited depth, and it is difficult for the passivation solution to passivate the corrosion-resistant alloy wire coils, especially the inner parts, through simple diffusion penetration in a short time. This prolongs the overall passivation time and reduces the overall passivation quality. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an integrated passivation process for corrosion-resistant alloy wire rolls. This invention maintains the overall relative integrity of the corrosion-resistant alloy wire rolls during the passivation process, eliminating the need for repeated unwinding and rewinding, resulting in less loss of the corrosion-resistant alloy wire rolls, lower processing costs, and higher processing efficiency.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] An integrated passivation process for corrosion-resistant alloy wire coils utilizes an integrated passivation device. The passivation device includes a receiving tank for containing passivation liquid, a first support rail and a second support rail disposed within the receiving tank, with the first support rail located below the second support rail. A clamping and pressure-regulating device is positioned between the first and second support rails. It also includes a hollow drum with multiple guide holes on its sidewalls communicating with the hollow interior. The process includes the following steps: S1, adding passivation liquid into the receiving tank according to the drum size, controlling the passivation liquid to submerge the alloy wire coil on the upper surface of the drum above the first support rail; S2, changing the pressure inside the hollow drum using the clamping and pressure-regulating device, controlling the flow medium to be drawn in or discharged from the guide holes; S3, after a predetermined time, controlling the drum to be lifted to the surface of the second support rail for air drying using the clamping and pressure-regulating device.

[0007] Preferably, the clamping pressure regulating device includes a U-shaped positioning frame, a rotary drive assembly is provided at the top of the positioning frame to control the directional rotation of the drum, and sealing pressure regulating assemblies are provided on the left and right sides of the positioning frame to change the pressure inside the hollow drum.

[0008] Preferably, both sides of the drum are fixed with guide pipes adapted to the sealing pressure regulating assembly. The sealing pressure regulating assembly is slidably connected to the positioning frame through the offset frame. The side wall of the positioning frame is also provided with a telescopic drive assembly for controlling the linear extension and retraction of the sealing pressure regulating assembly.

[0009] Preferably, the sealing pressure regulating assembly includes a first sealing sleeve assembly fixed to the positioning frame, and a second sealing sleeve assembly that is rotatably connected to the first sealing sleeve assembly. The second sealing sleeve assembly is located near and adapted to the guide tube. A one-way pumping assembly is provided between the first sealing sleeve assembly and the second sealing sleeve assembly.

[0010] Preferably, the unidirectional pumping assembly includes a first pumping pipe communicating with the first sealing sleeve assembly, a second pumping pipe communicating with the second sealing sleeve assembly, a pump communicating with the first sealing sleeve assembly and the second pumping pipe, and a pressure regulator located on one side of the pump, wherein the second sealing sleeve assembly extends into the first sealing sleeve assembly and is fixed to the pressure regulator.

[0011] Preferably, the second sealing sleeve assembly includes a sealing ring, a first guide rod fixed to the side wall of the sealing ring, a sealing tube fixed to the center of the sealing ring, the inner side of the sealing tube being connected to the one-way pumping assembly through a first rotating seal, a second guide rod fixed to the side wall of the sealing tube, a first guide hole adapted to the first guide rod being opened on the side wall of the drum, and a second guide hole adapted to the second guide rod being opened on the side wall of the guide tube.

[0012] Preferably, the first sealing sleeve assembly includes a sealing housing, the first side of which is rotatably connected to the second sealing sleeve assembly via a rotating connector, and the second side is connected to a drain pipe, the inner side of which is connected to a one-way pumping assembly via a second rotating seal.

[0013] Preferably, the upper end of the clamping and adjusting device is provided with a lifting device, which controls the drum at the upper end of the first bearing track and lifts it to a predetermined height.

[0014] Preferably, after sealing both sides of the drum, a flowing medium is pumped into or extracted from the drum to change the pressure inside the hollow drum. The flowing medium is air or a passivating liquid.

[0015] Preferably, the drum at the upper end of the first bearing track is clamped by the clamping and adjusting device and raised to a predetermined height, and the guide hole at the upper end of the drum is exposed to the air. Then, the drum is controlled to rotate in an directional manner by the clamping and adjusting device. During the rotation of the drum, the drum after being raised to a predetermined distance is controlled to reciprocate to a predetermined height.

[0016] The beneficial effects of this invention are as follows:

[0017] Compared with existing technologies, the above structural design, using a specially designed drum and related structures, can enhance the fluidity of the flowing medium by changing the internal pressure of the hollow drum. This enhances the passivation effect between the passivating liquid and the corrosion-resistant alloy wire roll, especially inside the roll, eliminating passivation blind zones to the greatest extent and improving the overall passivation quality of the corrosion-resistant alloy wire roll. Compared with the process of unwinding and drawing the roll for passivation, this process can maintain the relative integrity of the corrosion-resistant alloy wire roll during passivation, eliminating the need for repeated unwinding and rewinding, resulting in less loss of the corrosion-resistant alloy wire roll, lower processing costs, and faster processing efficiency.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] To address the problems mentioned in the background art, see Appendix Figure 1 -Appendix Figure 9 The integrated passivation process for corrosion-resistant alloy wire coils utilizes an integrated passivation device. The passivation device includes a receiving tank 100 containing passivation liquid, and a first bearing rail 300 and a second bearing rail 500 disposed within the receiving tank 100. The first bearing rail 300 is located below and to the side of the second bearing rail 500. Here, the first bearing rail 300 and the second bearing rail 500 are two parallel and spaced rails, capable of supporting the corrosion-resistant alloy wire coils.

[0030] A clamping and pressure regulating device 400 is provided between the first bearing rail 300 and the second bearing rail 500; it also includes a hollow drum 200, with multiple guide holes 210 on the side wall of the drum 200 communicating with the hollow interior; the corrosion-resistant alloy wire roll is wound and wound through the drum 200, and multiple guide holes 210 are arranged circumferentially around the side wall of the drum 200. After the corrosion-resistant alloy wire roll is wound up, the guide holes 210 are blocked and closed by the corrosion-resistant alloy wire roll.

[0031] This process specifically includes the following steps:

[0032] Step 1: Add passivating liquid into the receiving groove 100 according to the size of the drum 200, and control the passivating liquid to submerge the alloy wire roll on the surface of the upper end of the drum 200 of the first bearing track 300; the upper edge of the drum 200 is exposed to the air. Through the above design, the corrosion-resistant alloy wire roll on the surface of the drum 200 can be submerged and passivated by the passivating liquid, thus achieving the initial passivation treatment.

[0033] Step 2: The pressure inside the hollow drum 200 is changed by clamping the pressure regulating device 400. By changing the pressure inside the hollow drum 200, the state at multiple guide holes 210 can be changed. By increasing the pressure in the hollow part of the drum 200, the flowing medium inside the drum 200 can be discharged from the guide holes 210, or by decreasing the pressure in the hollow part of the drum 200, the flowing medium on the outside can be drawn in from the guide holes 210.

[0034] By changing the pressure inside the drum 200, the flow state of the medium around the guide hole 210 can be altered, thereby actively improving the fluidity of the medium around the corrosion-resistant alloy wire coil, reducing dead angles in passivation, eliminating air bubbles, and enhancing the passivation effect of the corrosion-resistant alloy wire coil.

[0035] Furthermore, the clamping and adjusting device 400 clamps the drum 200 at the upper end of the first bearing rail 300 and raises it to a predetermined height, controlling the upper part of the guide hole 210 of the drum 200 to be exposed to the air. At this time, part of the corrosion-resistant alloy wire coil is exposed to the air. Then, the clamping and adjusting device 400 controls the drum 200 to rotate in an directional manner. During the rotation of the drum 200, the drum 200 after being raised a predetermined distance is controlled to reciprocate to a predetermined height.

[0036] It should be noted that the reciprocating lifting rate is relatively low to avoid significant inertia that could lead to poor overall structural stability and accidents. During the reciprocating lifting of the drum 200, when the drum 200 is at its lowest point, the corrosion-resistant alloy wire coil on the surface of the drum 200 is completely submerged. When the drum 200 is at its highest point, some of the top guide holes 210 are exposed to air. During this alternating process, the passivating liquid or air can be alternately controlled to pass through the predetermined guide holes 210 to achieve the predetermined passivation purpose.

[0037] It should also be noted that after sealing both sides of the drum 200, the flow medium is pumped into or extracted from the drum 200 to change the pressure inside the hollow drum 200. The flow medium is air or passivating liquid. Through the above structural design, the flow medium can be automatically controlled by changing the pressure inside the drum 200. Compared with the traditional method of relying solely on static pressure permeation, this process can change the pressure inside and outside the drum 200 through pressure control, which can control the passivating liquid or air to flow faster from multiple guide holes 210, greatly improving the fluidity of the passivating liquid and air, enhancing the treatment effect of the passivating liquid, and improving the final overall passivation effect.

[0038] Through the above design, it is possible to control the exposure of some of the guide holes 210 to the air. At this time, the upper part of the corrosion-resistant alloy wire roll of the drum 200 is also exposed to the air. Most of the corrosion-resistant alloy wire roll is still immersed in the passivation liquid. During the directional rotation of the drum 200, the position of the corrosion-resistant alloy wire roll in each area is constantly changing, and it is in a periodic process of being immersed in the passivation liquid and exposed to the air.

[0039] By controlling the flow of passivating liquid at multiple guide holes 210, the passivating liquid can be directionally delivered from the inside to the outside or from the outside to the inside, which can enhance the contact between the passivating liquid and the inner part of the corrosion-resistant alloy wire coil and improve the passivation effect inside the corrosion-resistant alloy wire coil. By controlling the flow of air at multiple guide holes 210, the rapidly flowing air can eliminate air bubbles in the corrosion-resistant alloy wire coil, minimizing the possibility of air bubbles preventing the corrosion-resistant alloy wire coil from contacting the passivating liquid, maximizing the contact area of ​​the passivating liquid, eliminating passivation blind spots, and improving the overall passivation effect.

[0040] Step 3: After the predetermined time, the clamping and pressure regulating device 400 controls the drum 200 to be raised to the surface of the second bearing rail 500 for air drying. The drum 200 on the surface of the second bearing rail 500 is in an elevated state, offset from the passivation liquid at the bottom. During this process, the passivation liquid on the surface of the drum 200 naturally flows downward into the receiving tank 100 for automatic collection. At the same time, air drying equipment can be installed on both sides of the second bearing rail 500 to enhance the air drying effect of the drum 200. This not only achieves the recovery and collection of the passivation liquid, but also ensures that the drum 200 is relatively dry, preventing the passivation liquid from overflowing and causing contamination in the workshop during subsequent transfer.

[0041] In summary, through the above structural design, using a specially designed drum 200 and related structures, the fluidity of the flowing medium can be enhanced by changing the internal pressure of the hollow drum 200. This improves the contact passivation effect between the passivating liquid and the corrosion-resistant alloy wire roll, especially inside the roll, eliminating passivation blind zones to the greatest extent and improving the overall passivation quality of the corrosion-resistant alloy wire roll. Compared with the process of unwinding and drawing the roll for passivation, this process can maintain the relative integrity of the corrosion-resistant alloy wire roll during passivation, eliminating the need for repeated unwinding and rewinding, resulting in less loss of the corrosion-resistant alloy wire roll, lower processing costs, and faster processing efficiency.

[0042] Specifically, the clamping and pressure regulating device 400 includes a U-shaped positioning frame 410. A rotary drive assembly 440 is provided at the top of the positioning frame 410. The rotary drive assembly 440 controls the directional rotation of the drum 200. After the positioning frame 410 and the drum 200 are aligned, the rotary drive assembly 440 at the top of the positioning frame 410 can abut against the circumferential side wall of the drum 200. The rotary drive assembly 440 is an automatic force element that can drive the stable clamped drum 200 to rotate in an directional manner.

[0043] Sealing pressure regulating components 600 are respectively provided on the left and right sides of the positioning frame 410. The sealing pressure regulating components 600 change the pressure inside the hollow drum 200. The sealing pressure regulating components 600 can tightly clamp the two sides of the drum 200 and maintain a relatively sealed state, thereby changing the pressure inside the hollow drum 200 and realizing adjustment and control.

[0044] It should be noted that the sealing pressure regulating component 600 is clamped to the rotation center of the drum 200, which ensures that the drum 200 can rotate directionally around its own axis after being clamped stably, and ensures that the rotation drive component 440 can stably drive the drum 200 to rotate directionally.

[0045] Both sides of the drum 200 are fixed with guide pipes 220 adapted to the sealing pressure regulating assembly 600. The guide pipes 220 are connected to the hollow interior of the drum 200. The sealing pressure regulating assembly 600 is slidably connected to the positioning frame 410 through the offset frame 420. The side wall of the positioning frame 410 is also provided with a telescopic drive assembly 430 for controlling the linear extension and retraction of the sealing pressure regulating assembly 600.

[0046] Through the above structural design, the sealing and pressure regulating components 600 on both sides can be controlled to move closer to or further away from the sides of the drum 200, thereby clamping the drum 200 and preventing loosening, and meeting the processing needs under different conditions.

[0047] Specifically, the sealing pressure regulating assembly 600 includes a first sealing sleeve assembly 630 fixed to the positioning frame 410, and a second sealing sleeve assembly 610 rotatably connected to the first sealing sleeve assembly 630. The second sealing sleeve assembly 610 is located near and adapted to the guide pipe 220. A one-way pumping assembly 620 is disposed between the first sealing sleeve assembly 630 and the second sealing sleeve assembly 610. The one-way pumping assembly 620 enables continuous pumping of the flowing medium.

[0048] The second sealing sleeve assembly 610 can fit and clamp tightly against the inner side wall of the drum 200, maintaining a relatively sealed and stable state. The first sealing sleeve assembly 630 can be located on the outside to support and limit the second sealing sleeve assembly 610 and the inner drum 200, ensuring the relative stability of the inner structure during rotation. When the drum 200 is under negative pressure, the flowing medium can enter the hollow interior of the drum 200 from the outside through the guide hole 210, then through the guide pipe 220, and then sequentially through the second sealing sleeve assembly 610 and the one-way pumping assembly 620, finally exiting from the first sealing sleeve assembly 630. When the drum 200 is under positive pressure, the flow path of the flowing medium is reversed. In this process, the flowing medium is drawn in from the first sealing sleeve assembly 630, sequentially passes through the one-way pumping assembly 620 and the second sealing sleeve assembly 610, enters the inner side of the drum, and finally exits from the outside through the guide hole 210.

[0049] It should be noted that during a passivation process, the pressure in the hollow part of the drum 200 can be increased or decreased individually to control the flow medium to be discharged or drawn in from the guide hole 210.

[0050] The flow direction of the fluid medium can be changed by altering the unidirectional flow direction of the check valves inside the first pumping pipe 621 and the second pumping pipe 622. This allows for either increasing or decreasing the pressure in the hollow portion of the drum 200. By changing the internal pressure of the hollow drum 200, the fluidity of the fluid medium is enhanced, thereby improving the passivation effect between the passivating liquid and the corrosion-resistant alloy wire roll, especially inside the roll, and eliminating passivation blind zones to the greatest extent possible.

[0051] Two different sets of equipment can be selected to achieve the pressure boosting and negative pressure functions respectively, or the above-mentioned one-way valve can be selected as an electromagnetic variable one-way valve, and the pressure boosting or negative pressure mode can be selected according to the specifications of different drums and rolls.

[0052] Specifically, the unidirectional pumping assembly 620 includes a first pumping pipe 621 connected to the first sealing sleeve assembly 630, a second pumping pipe 622 connected to the second sealing sleeve assembly 610, and a one-way valve installed inside both the first pumping pipe 621 and the second pumping pipe 622 to ensure unidirectional flow of the medium. It also includes a pump 623 connected to the first sealing sleeve assembly 630 and the second pumping pipe 622. The first sealing sleeve assembly 630 is connected to the pump 623 through the first pumping pipe 621, and a pressure regulator 624 located on one side of the pump 623. The second sealing sleeve assembly 610 extends into the first sealing sleeve assembly 630 and is fixed to the pressure regulator 624. The pump 623 is fixed inside the first sealing sleeve assembly 630, that is, the pressure regulator 624 periodically squeezes the pump 623 as the second sealing sleeve assembly 610 rotates.

[0053] The pump 623 mentioned above can be a pumping airbag with expansion elasticity or a peristaltic hose arranged in a circumferential direction. The pressure regulator 624 mentioned above can be a single-protruding cam or a multi-protruding cam that is adapted to it.

[0054] During the rotation of the drum 200 as a whole, the second sealing sleeve assembly 610 can be driven to rotate synchronously. During the rotation of the second sealing sleeve assembly 610, the fixed pressure regulator 624 can be driven to rotate synchronously. The pressure regulator 624 can cooperate with the pump 623 to realize unidirectional pumping of the flowing medium.

[0055] When the pumper 623 is selected as the pumping airbag, the pressure regulator 624 intermittently contacts the pumping airbag to control the periodic expansion and contraction of the pumping airbag. During the contraction of the pumping airbag, the flowing medium is pumped out, and during the expansion and reset of the pumping airbag, the flowing medium is extracted, thus achieving unidirectional pumping of the flowing medium.

[0056] When the pump 623 is selected as a peristaltic hose, the multi-protruding cam that rotates in a specific direction can contact different positions of the peristaltic hose to achieve unidirectional pumping of the flowing medium. The above process is similar to the pumping process of the airbag, and will not be described in detail here.

[0057] Through the above structural design, the pumping of the flowing medium can be automatically realized during the rotation of the drum 200, and the pumping rate of the flowing medium can be synchronously adjusted according to the rotation rate of the drum 200, so as to achieve efficient automatic control and meet the processing requirements.

[0058] Specifically, the second sealing sleeve assembly 610 includes a sealing ring 611, a first guide rod 612 fixed to the side wall of the sealing ring 611, and a sealing tube 613 fixed at the center of the sealing ring 611. The sealing tube 613 can be tightly fitted with the guide tube 220 on the side wall of the drum 200 to allow the flow medium to flow between the two. An elastic sealing gasket can be set at the connection position to ensure relative sealing at the connection position after tightness. The inner side of the sealing tube 613 is connected to the one-way pumping assembly 620 through a first rotating seal 615.

[0059] A second guide rod 614 is fixed to the side wall of the sealing tube 613. A first guide hole 230 adapted to the first guide rod 612 is opened on the side wall of the drum 200. A second guide hole 221 adapted to the second guide rod 614 is opened on the side wall of the guide tube 220. Through the above structural design, the sealing ring 611 and the sealing tube 613 can be accurately positioned to ensure the accuracy of their docking position. This ensures that the drum 200 can subsequently connect to the second sealing sleeve assembly 610 and rotate around its own axis, ensuring stable rotation drive control.

[0060] The first sealing sleeve assembly 630 includes a sealing housing 633. The first side of the sealing housing 633 is rotatably connected to the second sealing sleeve assembly 610 via a rotating connector 634, and the second side is connected to a drain pipe 631. The inner side of the drain pipe 631 is connected to the one-way pumping assembly 620 via a second rotating seal 632. The drain pipe 631 can guide the flow medium at the outer position, control the flow of the flow medium within a predetermined range, and meet the processing requirements.

[0061] By providing rotating seals on both sides, the pumping of the flowing medium can be kept stable during the rotation of the second sealing sleeve assembly 610. The rotating seals ensure that the two relatively rotating and sealed sealing rings are connected in a sealed manner.

[0062] When the control drum 200 is under negative pressure, the drain pipe 631 can be extended to the side of the receiving tank 100 away from the clamping pressure regulating device 400 when the passivation liquid is extracted. This design can promote the passivation liquid at the edge of the receiving tank 100 to flow automatically towards the clamping pressure regulating device 400, promote the flow and mixing of the passivation liquid in the receiving tank 100, and ensure the long-term, efficient and stable passivation process.

[0063] A lifting device 450 is provided at the upper end of the clamping and adjusting device 400. The lifting device 450 controls the drum 200 at the upper end of the first bearing rail 300 and raises it to a predetermined height, controlling the upper part of the guide hole 210 of the drum 200 to be exposed to the air. The lifting device 450 can be a high-precision electrically controlled telescopic rod or a threaded telescopic assembly, which can accurately adjust the height of the drum 200 according to the size of the drum 200 and the winding thickness of the corrosion-resistant alloy wire roll, so as to meet the passivation needs at different stages of the passivation process.

[0064] Finally, it should be noted that a horizontal electric trolley can be installed on the upper end of the lifting device 450, or a retractable bearing structure can be installed on the side of the second bearing rail 500 near the first bearing rail 300, to achieve stable switching and conveying of the drum 200. The drum 200 can be controlled to move along a predetermined track by a push structure on its outer side, or the first bearing rail 300 and the second bearing rail 500 can be designed as inclined structures to control the drum 200 and the second bearing rail 500 to roll under the action of gravity. It should be noted that an intercepting structure should be designed on the lower side of the first bearing rail 300 and the second bearing rail 500 to prevent the drum 200 from derailing. The above design content is well known to those skilled in the art, and this article does not involve any improvements, so it will not be elaborated on further in this article.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
