Description

Technical Field

[0001] The present invention relates to the technical field of electroplating, and in particular to a steel wire electroplating processing method and equipment. Background Art

[0002] Electroplating other metals (zinc, copper, etc.) on the surface of steel wire can enhance the overall corrosion resistance of the steel wire and optimize the overall material and performance of the steel wire; through electroplating, the metal material can be evenly and quickly attached to the surface of the steel wire.

[0003] After electroplating, the steel wire can be further fused with the metal material on the outside through thermal diffusion treatment, which helps the steel wire and the metal coating on the outside to diffuse with each other to form a composite alloy layer with better performance, so as to overcome some defects of electroplating. Thermal diffusion is formed through electromagnetic induction heating, and the thermal diffusion temperature varies according to the melting temperature of the metal coating.

[0004] During the thermal diffusion process, the outer side of the metal layer easily comes into contact with oxygen in the air to form oxidized compounds, such as zinc oxide, which makes the surface metal layer brittle and affects the performance of the composite material after thermal diffusion. Some designs attach a protective layer (such as borax film) to the surface of the steel wire after electroplating to isolate oxygen and avoid the formation of metal oxides. However, the above operation requires at least one additional step between electroplating and thermal diffusion. For some liquid oxide protective layers, they also need to be quickly dried, which increases the steel wire electroplating process, increases the length of the production line, and reduces the efficiency of the electroplating process.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] To solve the problems mentioned in the background art; a method for electroplating steel wires, which uses an electroplating treatment tank 200 to electroplate the steel wires 300 passing through it; a relatively sealed treatment chamber is formed inside the electroplating treatment tank 200. Except for the side walls having openings for the steel wires 300 to pass through, the surrounding is in a closed state. The treatment chamber includes a first storage tank 2001, a first transition tank 2002, a heat treatment tank 2004, a second transition tank 2006, and a second storage tank 2007 arranged in sequence.

[0030] The first storage tank 2001 and the first transition tank 2002 store a first treatment liquid. Through the first treatment liquid, the electroplating process on the surface of the steel wires can be completed. The second transition tank 2006 and the second storage tank 2007 store a second treatment liquid. Through the second treatment liquid, the electroplating process of other metals can be continued, or other treatments on the surface of the steel wires after electroplating and thermal diffusion can be completed.

[0031] A thermal diffusion device is provided in the heat treatment tank 2004. The thermal diffusion device is selected as an electromagnetic induction heating device. During the process of the steel wires passing through, electromagnetic induction heating can be carried out in a non-contact state, controlling the coating metal to be in a molten state and mutually performing thermal diffusion with the steel wires to form a mutually fused composite alloy inside.

[0032] Specifically, it includes the following steps:

[0033] S1. Control the steel wires 300 to pass through the electroplating treatment tank 200, complete the electroplating process through the first storage tank 2001, complete the thermal diffusion process through the heat treatment tank 2004, and complete the treatment process through the second storage tank 2007.

[0034] S2. Pump a protective gas into the heat treatment tank 2004. At the same time, control the first treatment liquid and the second treatment liquid to flow directionally on both sides of the heat treatment tank 2004 to form a liquid seal structure, and control the steel wires 300 to complete the thermal diffusion treatment in an oxygen-isolated environment.

[0035] Through the above method, there is no need to add an additional coating protection process between electroplating and thermal diffusion processing. Only need to control the directional flow of the treatment liquids on both sides to form a liquid seal structure. Through the liquid seal structure, oxygen can be prevented from entering the heat treatment tank 2004, avoiding the oxidation of the metal layer during the thermal diffusion treatment; the steps of steel wire electroplating processing are streamlined through this processing method, the processing equipment is simplified, and at the same time, the electroplating processing efficiency is greatly improved, ensuring the comprehensive performance of the steel wires after thermal diffusion treatment.

[0036] Refer to the appendix Figure 1 - appendix Figure 8The steel wire electroplating processing equipment used for steel wire electroplating processing includes a plating treatment tank 200 for the steel wire 300 to pass through, the plating treatment tank 200 stores a treatment liquid located on the moving path of the steel wire 300, and the electroplating treatment tank 200 is also provided with an electroplating device, through which the metal can be electroplated on the surface of the steel wire to form a metal coating, thereby enhancing the anti-oxidation performance of the steel wire surface.

[0037] The treatment liquid here can be selected as a zinc sulfate solution, which can electroplate zinc ions on the surface of the steel wire to form a continuous and complete metal zinc coating during the electroplating process.

[0038] The electroplating processing tank 200 here includes a processing tank body 220 and a processing tank cover 230. Several partition plates 210 are arranged between the processing tank body 220 and the processing tank cover 230. The side wall of the partition plate 210 is provided with a guide hole 211 for the steel wire 300 to pass through. The partition plate 210 and the processing tank body 220 and the processing tank cover 230 are relatively sealed to form a plurality of processing chambers. The partition plate 210 and the processing tank body 220 and the processing tank cover 230 are relatively closed. A sealing gasket can be installed between the two to enhance the sealing effect. The size of the guide hole 211 is larger than the size of the steel wire and can allow the steel wire to pass through. At the same time, part of the processing liquid can flow toward the lower side through the guide hole 211. When there is enough liquid, a liquid sealing structure can be formed at the guide hole 211 to ensure the relative sealing between the multiple processing chambers.

[0039] Specifically, the processing chamber includes a storage tank 1 2001 for storing processing liquid 1 and a storage tank 2 2007 for storing processing liquid 2. A heat treatment tank 2004 for thermally diffusing the steel wire 300 is arranged between the storage tank 1 2001 and the storage tank 2 2007. The steel wire can be electromagnetically inductively heated by the heat treatment tank 2004 to achieve thermal diffusion treatment, so as to enhance the comprehensive performance of the steel wire after electroplating.

[0040] In order to collect the overflowing treatment liquid from the guide hole 211 and ensure the normal progress of the overall electroplating and heat diffusion, a transition groove 2002 is provided on the heat treatment groove 2004 near the storage groove 2001 side. By providing the transition groove 2002, the treatment liquid 1 overflowing from the storage groove 2001 side can be collected. A transition groove 2006 is provided on the heat treatment groove 2004 near the storage groove 2007 side. By providing the transition groove 2006, the treatment liquid 2 overflowing from the storage groove 2007 side can be collected.

[0041] A pumping mechanism 400 is also provided at the lower end of the electroplating treatment tank 200. The pumping mechanism 400 includes a first pumping device 410 disposed between the storage tank 1 2001 and the transition tank 1 2002 for controlling the directional flow of the treatment liquid, and also includes a fourth pumping device 440 disposed between the transition tank 2006 and the storage tank 2 2007 for controlling the directional flow of the treatment liquid 2. Specifically, the treatment liquid 1 in the transition tank 1 2002 can be pumped into the storage tank 1 2001 through the first pumping device 410, and the treatment liquid 2 in the transition tank 2006 can be pumped into the storage tank 2 2007 through the fourth pumping device 440.

[0042] The heat treatment tank 2004 is filled with protective gas, and the treatment liquid 1 and the treatment liquid 2 flow in a directional manner on both sides of the heat treatment tank 2004 to form a liquid sealing structure. The electroplating treatment tank 200 can ensure that the fixed connection of the heat treatment tank 2004 is in a relatively sealed state. The liquid sealing structure can ensure that the heat treatment tank 2004 is in a relatively sealed state along the direction of the steel wire 300. It can prevent oxygen in the outside air from entering the heat treatment tank 2004 and reacting with the molten metal coating to produce an oxidation reaction, thereby avoiding the formation of metal oxides and improving the quality of the metal coating after heat treatment.

[0043] The protective gas here can be selected from common protective gases such as nitrogen and helium that do not react with metals.

[0044] It should be noted here that in order to ensure the relative sealing of the liquid sealing structures on both sides, it is necessary to ensure that the liquid level height of the treatment liquid 1 and the treatment liquid 2 is greater than the height of the guide hole 211. The treatment liquid can be used to seal the corresponding guide holes 211 on both sides of the heat treatment tank 2004 to prevent oxygen in the environment from entering from there.

[0045] A drying tank 2003 is also provided on the side of the heat treatment tank 2004 close to the transition tank 1 2002, and a cooling tank 2005 is also provided on the side of the heat treatment tank 2004 close to the transition tank 2 2006. A resistance heating device is provided in the drying tank 2003, which can increase the temperature in the drying tank 2003 and accelerate the drying of the steel wire 300 in the drying tank 2003; the cooling tank 2005 here is connected with a cooling structure, which can reduce the temperature in the cooling tank 2005, and can cool the steel wire 300 in the heat treatment tank 2004 after induction heating, and control the steel wire 300 to enter the treatment liquid 2 at a relatively normal temperature, so as to ensure the subsequent normal processing of the steel wire 300.

[0046] The pumping mechanism 400 also includes a second pumping device 420 for controlling the directional flow of the protective gas. The second pumping device 420 can control the protective gas to move in a path opposite to the movement of the steel wire 300. Through the above design, the heated gas in the heat treatment tank 2004 can enter the drying tank 2003 to assist in heating the part of the steel wire 300, so that the heat can be fully utilized.

[0047] Specifically; the second pumping device 420 includes a second pumping pipe 421 and a second pumping component 422 connected in series to the inside of the second pumping pipe 421, and the second pumping component 422 can control the directional compression flow of the gas in the second pumping pipe 421; the first end of the second pumping pipe 421 passes through the transition groove 2002 and extends to the top of the transition groove 2002, and the second end of the second pumping pipe 421 passes through the cooling groove 2005 and is connected to the cooling groove 2005.

[0048] Under the pumping action of the second pumping component 422, the first end of the second pumping pipe 421 can continuously inhale the protective gas, and the second end of the second pumping pipe 421 can continuously eject the gas, and the protective gas flows directionally from the second end of the second pumping pipe 421 toward the first end of the second pumping pipe 421, and the protective gas in the heat treatment tank 2004 is directionally pumped into the drying tank 2003 to assist in heating and drying the steel wire 300; at the same time, it also prevents humid gas from entering the heat treatment tank 2004 to affect the induction heating of the steel wire 300.

[0049] It should be noted that the first end of the second pumping pipe 421 is installed on the top of the transition tank 2002, and the top of the transition tank 2002 is always in a dry state. The gas in the drying tank 2003 can enter through the guide hole 211 between the transition tank 2002 and the drying tank 2003, and finally be sucked into the second pumping pipe 421.

[0050] It should also be noted that a drying component 423 is also connected in series in the second pumping pipe 421, and the inhaled gas can be fully dried by the drying component 423. The second pumping pipe 421 here can be set as a closed loop, and the fully dried gas can be re-pumped into the heat treatment tank 2004 to protect the steel wire 300.

[0051] The pumping mechanism 400 also includes a third pumping device 430 for controlling the directional flow of the cooling medium. The third pumping device 430 includes a third pumping pipe 431 close to the second pumping pipe 421. A third pumping component 432 is connected in series inside the third pumping pipe 431. A heat exchange component 424 is arranged between the third pumping pipe 431 and the second pumping pipe 421.

[0052] The cooling medium can be pumped into the third pumping pipe 431 for directional flow through the third pumping device 430, the third pumping pipe 431 and the second pumping pipe 421 can be fully contacted through the heat exchange component 424, and the heat in the second pumping pipe 421 can be fully absorbed and exchanged through the second pumping pipe 421 to reduce the temperature of the protective gas in the second pumping pipe 421.

[0053] The cooled protective gas in the second pumping pipe 421 can be pumped back into the cooling tank 2005 to fully cool the steel wire 300 inside; the cooling medium here can be selected as a liquid cooling medium to improve the overall heat exchange effect.

[0054] Specifically, the first pumping device 410 includes a first pumping pipe 411 and a first pumping assembly 412 serially connected to the first pumping pipe 411. The first end of the first pumping pipe 411 passes through the transition tank 2002 and is located at the bottom of the transition tank 2002. A float valve group 413 is also provided at the first end of the first pumping pipe 411. The treatment liquid 1 at the bottom of the transition tank 2002 can be extracted through the first pumping pipe 411, and the extracted treatment liquid 1 can be pumped back into the storage tank 2001 through the first pumping assembly 412.

[0055] By setting the float valve group 413, the opening and closing state of the first end of the first pumping pipe 411 can be controlled. When the liquid level in the transition tank 2002 is low, the first end of the first pumping pipe 411 is controlled to be in a closed state, which can prevent the first pumping pipe 411 from pumping the gas in the transition tank 2002 into the storage tank 2001, avoid abnormal phenomena in the overall system, realize automatic control, and ensure the normal progress of the overall electroplating.

[0056] Specifically, the float valve group 413 includes a float valve base 4131, a guide opening 4132 is opened at the bottom of the float valve base 4131, a float valve body is arranged inside, and a float 4133 connected to the float valve body is arranged on the top. When the liquid level is higher than the lowest point of the float 4133, under the action of buoyancy, the float 4133 here can drive the float valve body to move upward. When the float valve body moves upward to a predetermined height, it can be completely offset from the guide opening 4132. At this time, the first end of the first pumping pipe 411 can extract excess treatment liquid to prevent excess treatment liquid from entering the drying tank 2003 and affecting subsequent treatment procedures.

[0057] When the liquid level is low, the above-mentioned action process is reversed. Under the action of the float valve body, the guide opening 4132 is in a closed state, which can prevent the first pumping component 412 from extracting gas and ensure the normal operation of the entire system.

[0058] The fourth pumping device 440 on the other side can also select the above-mentioned floating opening and closing structure to prevent gas from being pumped into the second storage tank 2007. Through the above-mentioned structural design, there is no need to accurately control the amount of liquid pumped by the pumping component per unit time, which can achieve automatic balance of the treated liquid and reduce the difficulty of control.

[0059] Specifically, the above-mentioned pumping assembly includes a pumping shell 4001, and a pumping piston 4002 is sealed and slidably connected inside the pumping shell 4001. A pumping rod 4004 is fixed to the side wall of the pumping piston 4002. The end portion of the pumping rod 4004 penetrates the pumping shell 4001 and extends to the outside. A reset spring 4003 for resetting is sleeved on the outside of the pumping rod 4004. A pumping chamber 4006 is formed between the side of the pumping piston 4002 away from the pumping rod 4004 and the pumping shell 4001, and the pumping chamber 4006 is connected to a pumping joint 4005 with two built-in one-way valves.

[0060] The return spring 4003 here can pull the second pumping assembly 422 to move toward the outside, that is, the second pumping assembly 422 is moved toward the outside. Figure 7 The upper part of the pumping chamber 4006 can be in the largest state; during the process of pumping liquid, the pumping rod 4004 is pushed toward the adjacent Figure 7 Moving in the middle-lower direction can compress the pumping chamber 4006 until the pumping chamber 4006 is in the smallest state; repeating the above actions can control the pumping chamber 4006 to periodically expand and shrink. In this process, the one-way valve can be used to achieve continuous pumping of the processing liquid and the protective gas.

[0061] A driving device 500 is arranged outside the pumping mechanism 400. The driving device 500 is located outside the multiple pumping components and is used to control the multiple pumping components to synchronously complete pumping. By setting the driving device 500, the reciprocating control process can be automatically completed, and the multiple pumping rods 4004 can be pushed to move synchronously, thereby ensuring the unification of the front and back of the electroplating processing equipment and ensuring the overall normal electroplating processing control.

[0062] Specifically, the driving device 500 includes an extrusion plate 520 and a driving telescopic rod 510 for controlling the reciprocating linear movement of the extrusion plate 520. The extrusion plate 520 extends toward both sides, and a plurality of pumping components are located on the moving path of the extrusion plate 520.

[0063] During the driving control process, the telescopic rod 510 is periodically controlled to drive the extrusion plate 520 to move back and forth. Under the extrusion of the extrusion plate 520, the pumping rod 4004 can be pushed toward the inner direction to complete the unidirectional continuous pumping of the treatment liquid and the protective gas. There is no connection between the extrusion plate 520 and the multiple pumping rods 4004. During the process of driving the telescopic rod 510 and the extrusion plate 520 to contract, the multiple pumping rods 4004 can be reset under the action of elastic force, and the pumping chamber 4006 completes the unidirectional extraction of the treatment liquid and the protective gas during the expansion process.

[0064] It should be noted that, for the structure equipped with the float valve group 413, when one side of the float valve group 413 is in a closed state, under the action of negative pressure, the return spring 4003 cannot pull the pumping piston 4002 to return to its original position, and the corresponding pumping rod 4004 is still in a contracted state and will not be squeezed and driven by the driving device 500, thereby avoiding pumping gas into the treatment liquid.

[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 principle of the present invention should be included in the protection scope of the present invention.
