Description

Technical Field

[0001] This utility model relates to the technical field of wire processing equipment, and more specifically, to a wire oxalic acid plating device. Background Technology

[0002] Stainless steel wire is a metal material used to process various parts. In the existing technology, when parts manufacturers purchase stainless steel wire and cold-forge it to form different parts, the poor lubrication performance of the stainless steel wire surface can easily damage the cold forging die. For example, when screw manufacturers purchase stainless steel wire and cold-forge it into screws, the cold forging die is easily worn, which affects its service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wire oxalic acid plating device, which can form an oxalic acid plating layer on the surface of stainless steel wire, thereby improving the lubrication performance between the stainless steel wire and the mold during the process of processing stainless steel wire into different parts, and can better reduce the coefficient of friction, thereby reducing mold wear and increasing mold service life.

[0004] This utility model provides a wire oxalic acid plating device, including a base, a plating solution tank, a cleaning tank, a drying tank, and a hot air blower. The plating solution tank, cleaning tank, drying tank, and hot air blower are fixed to the base from left to right. The plating solution tank is used to inject oxalic acid solution. A first electric heating tube and a first thermocouple are fixed on the rear inner wall of the plating solution tank. Both the first electric heating tube and the first thermocouple are electrically connected to a first controller. The cleaning tank is used to inject clean water. A second electric heating tube and a second thermocouple are fixed on the rear inner wall of the cleaning tank. Both the second electric heating tube and the second thermocouple are electrically connected to a second controller. A perforated plate for supporting the wire coil is provided on the inner side of the drying tank. A hot air cavity is formed between the perforated plate and the inner bottom of the drying tank. The air outlet of the hot air blower is connected to the hot air cavity. A drain pipe is provided at the bottom of the hot air cavity.

[0005] By adopting the above-described structure, after the coiled stainless steel wire is immersed in the plating bath, the oxalic acid solution injected into the plating bath can chemically react with the stainless steel wire and form an oxalic acid coating on the surface of the stainless steel wire. This improves the lubrication performance between the stainless steel wire and the mold during the process of processing the stainless steel wire into different parts, thereby better reducing the coefficient of friction, reducing mold wear, and increasing the service life of the mold.

[0006] In one possible implementation, a plurality of support columns arranged in an array are fixed on the lower end face of the perforated plate, and the lower end of each support column abuts against the inner bottom of the drying tank to form a hot air cavity between the perforated plate and the inner bottom of the drying tank. With the above structure, after the lower end of each support column abuts against the inner bottom of the drying tank, a hot air cavity can be easily formed between the perforated plate and the inner bottom of the drying tank, and the plurality of support columns arranged in an array can reliably support the perforated plate.

The first circulating pump is fixed to a base, its inlet is connected to the bottom of the plating bath via the inlet pipe, and its outlet is connected to the upper inner cavity of the plating bath via the outlet pipe. The first circulating pump is electrically connected to a first controller. With this structure, when the first circulating pump operates, it can draw oxalic acid solution from the plating bath via the inlet pipe, and the oxalic acid solution can be returned to the inner side of the upper part of the plating bath via the outlet pipe, thereby allowing the oxalic acid in the plating bath to be... The solution flows sufficiently to allow the oxalic acid solution to effectively remove the oxide layer from the wire surface. Furthermore, the sufficient flow of the oxalic acid solution facilitates heating by the first electric heating element, which in turn allows the heated solution to more easily remove the oxide layer from the wire surface. In addition, the combined action of the first thermocouple, the first controller, and the first electric heating element controls whether the first electric heating element heats the oxalic acid solution in the plating bath, maintaining the temperature of the oxalic acid solution within a specific temperature range to ensure effective removal of the oxide layer from the wire surface.

[0008] In one possible implementation, a first discharge valve is connected to the inlet pipe; by setting the first discharge valve, when the first discharge valve is opened, the old oxalic acid solution in the plating bath can be discharged through the first discharge valve.

[0009] In one possible implementation, the wire oxalic acid plating device further includes a second circulation pump, an inlet pipe, and an outlet pipe. The second circulation pump is fixed to the base. The inlet of the first circulation pump is connected to the bottom of the cleaning tank via the inlet pipe, and the outlet of the first circulation pump is connected to the inner cavity of the upper part of the cleaning tank via the outlet pipe. The second circulation pump is electrically connected to a second controller. With this structure, when the second circulation pump is working, it can draw water from the clean water tank via the inlet pipe, and the water can be returned to the inner side of the upper part of the clean water tank via the outlet pipe, thereby enabling the cleaning tank to achieve the desired cleaning effect. The water in the tank flows freely to ensure thorough cleaning of the wire surface. Furthermore, the flowing water facilitates heating by the second electric heating element, allowing for more effective cleaning of the wire surface. In addition, the combined action of the second thermocouple, the second controller, and the second electric heating element controls whether the heating of the water in the tank is controlled, maintaining the water temperature within a specific range to ensure thorough cleaning of the wire surface.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] See Figure 1-2 As shown in the figure, this application discloses a wire oxalic acid plating device, including a base 1, a plating solution tank 2, a cleaning tank 3, a drying tank 4, and a hot air blower 5. The plating solution tank 2, the cleaning tank 3, the drying tank 4, and the hot air blower 5 are fixed on the base 1 from left to right. The plating solution tank 2 is used to inject oxalic acid solution. A first electric heating tube 21 and a first thermocouple 22 are fixed on the rear inner wall of the plating solution tank 2. The first electric heating tube 21 and the first thermocouple 22 are both electrically connected to a first controller. The cleaning tank 3 is used to inject clean water. A second electric heating tube 31 and a second thermocouple 32 are fixed on the rear inner wall of the cleaning tank 3. The second electric heating tube 31 and the second thermocouple 32 are both electrically connected to a second controller. A perforated plate 6 for supporting the wire coil is provided on the inner side of the drying tank 4. A hot air cavity 41 is formed between the perforated plate 6 and the inner bottom of the drying tank 4. The air outlet of the hot air blower 5 is connected to the hot air cavity 41. A drain pipe 42 is provided at the bottom of the hot air cavity 41.

[0018] A number of support columns 61 arranged in an array are fixed on the lower end face of the perforated plate 6. The lower end of each support column 61 abuts against the inner bottom of the drying tank 4 so that a hot air cavity 41 is formed between the perforated plate 6 and the inner bottom of the drying tank 4. With the above structure, after the lower end of each support column abuts against the inner bottom of the drying tank, a hot air cavity can be easily formed between the perforated plate and the inner bottom of the drying tank, and the number of support columns arranged in an array can reliably support the perforated plate.

[0019] The wire oxalic acid plating apparatus also includes a first circulation pump 23, an inlet pipe 24, and an outlet pipe 25. The first circulation pump 23 is fixed on the base 1. The inlet of the first circulation pump 23 is connected to the bottom of the plating bath 2 through the inlet pipe 24, and the outlet of the first circulation pump 23 is connected to the upper inner cavity of the plating bath 2 through the outlet pipe 25. The first circulation pump 23 is electrically connected to a first controller. With this structure, when the first circulation pump is working, it can draw oxalic acid solution from the plating bath through the inlet pipe, and the oxalic acid solution can be sent back to the inner side of the upper part of the plating bath through the outlet pipe, thereby allowing the oxalic acid solution in the plating bath to flow sufficiently, so as to facilitate the plating process. The acid solution effectively removes the oxide layer on the wire surface and forms an oxalic acid plating layer on the wire surface. Furthermore, the sufficient flow of the oxalic acid solution facilitates heating by the first electric heating element. The heated oxalic acid solution more easily removes the oxide layer on the wire surface and forms an oxalic acid plating layer. In addition, the cooperation of the first thermocouple, the first controller, and the first electric heating element allows control over whether the first electric heating element heats the oxalic acid solution in the plating bath, maintaining the temperature of the oxalic acid solution within a certain temperature range. This ensures that the oxalic acid solution effectively removes the oxide layer on the wire surface and forms an oxalic acid plating layer on the wire surface.

[0020] A first discharge valve 26 is connected to the inlet pipe 24; by setting the first discharge valve, when the first discharge valve is opened, the old oxalic acid solution in the plating bath can be discharged through the first discharge valve.

[0021] The wire oxalic acid plating device also includes a second circulation pump 33, an inlet pipe 34, and an outlet pipe 35. The second circulation pump 33 is fixed on the base 1. The inlet of the first circulation pump 23 is connected to the bottom of the cleaning tank 3 through the inlet pipe 34, and the outlet of the first circulation pump 23 is connected to the upper inner cavity of the cleaning tank 3 through the outlet pipe 35. The second circulation pump 33 is electrically connected to the second controller. With this structure, when the second circulation pump is working, it can draw water from the clean water tank through the inlet pipe, and the water can be sent back to the inner side of the upper part of the clean water tank through the outlet pipe, thereby enabling the clean water tank to... The water in the tank is allowed to flow freely to thoroughly clean the impurities adsorbed on the surface of the wire. Furthermore, the free flow of water facilitates heating by the second electric heating element, making it easier for the heated water to clean the impurities. In addition, the combined action of the second thermocouple, the second controller, and the second electric heating element allows for precise control of whether the heating element heats the water in the tank, maintaining the water temperature within a specific range to ensure thorough cleaning of the impurities adsorbed on the wire.

[0022] A second drain valve 36 is connected to the water inlet pipe 34; by setting the second drain valve, when the second drain valve is opened, the old clean water in the cleaning tank can be discharged through the second drain valve.

[0023] When using this invention, the coiled wire is first hoisted into the plating bath by a crane. At this time, the oxalic acid solution in the plating bath, heated by the first electric heating element, begins to remove the oxide layer on the surface of the wire, forming an oxalic acid plating layer. After the wire has been immersed in the oxalic acid solution for a period of time (e.g., 1 hour), the wire is hoisted from the plating bath into a cleaning tank by a crane. Here, the clean water in the cleaning tank removes impurities adsorbed on the surface of the wire. Then, the wire is removed from the cleaning tank by a crane. The wire is hoisted from the cleaning tank into the drying tank. At this point, the wire can be supported on the perforated plate, and the hot air delivered by the hot air blower can enter the hot air chamber. The hot air entering the hot air chamber can pass through the perforated plate and dry the wire located on the perforated plate. In addition, if any water remaining on the wire drips onto the perforated plate, the water can pass through the perforated plate and enter the hot air chamber, and the water entering the hot air chamber can be discharged through the drain pipe. Finally, after the coiled wire is dried, it is hoisted out of the drying tank again by a crane.

[0024] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
