Abstract
Description
Technical Field
[0001] This utility model relates to the field of galvanized parts processing technology, specifically to a galvanizing bath for galvanized parts processing. Background Technology
[0002] In the galvanized parts processing industry, fluxing is a key step in the hot-dip galvanizing production process. The main function of fluxing is to remove oxides from the surface of the workpiece, prevent the workpiece from re-oxidizing when immersed in the zinc liquid, and enhance the wettability between the zinc liquid and the workpiece surface, thereby improving the quality and adhesion of the galvanized layer. Therefore, a fluxing bath for galvanized parts processing is needed for fluxing operations.
[0003] However, in the existing technology, the fluxing baths used for galvanizing parts are usually static fluxing solutions. The fluxing solution lacks effective stirring and circulation in the bath, resulting in uneven distribution of fluxing solution concentration. The composition of the fluxing solution in contact with different parts of the workpiece is different, which leads to inconsistent fluxing effect. Insufficient fluxing in some areas affects the quality and uniformity of the galvanized layer. Due to the different fluxing solution concentrations, there will be thickness differences after galvanizing, which reduces the product qualification rate. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The purpose of this invention is to provide a fluxing bath for galvanizing parts, in order to solve the problem mentioned in the background art that the fluxing solution lacks effective stirring and circulation in the bath, resulting in uneven concentration distribution of the fluxing solution.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the present invention provides the following technical solution: a galvanizing bath for processing galvanized parts, comprising a heating support box, a galvanizing bath fixedly installed at the top of the heating support box, a PLC controller fixedly installed on one side of the galvanizing bath, and a circulating galvanizing mechanism provided on one side of the galvanizing bath.
[0008] The circulating plating mechanism includes a circulating pump. The circulating pump is fixedly installed on one side of the plating tank and is electrically connected to a PLC controller. A liquid extraction pipe is fixedly installed on one side of the circulating pump, extending to the bottom of the plating tank. A liquid delivery telescopic pipe is fixedly installed at the top of the circulating pump. A spray water collection pipe is fixedly installed on the side of the liquid delivery telescopic pipe away from the circulating pump. Several spray nozzles are evenly fixedly installed at the bottom of the spray water collection pipe. A U-shaped bracket is fixedly installed at the top of the plating tank, and a hydraulic cylinder is fixedly installed at the top of the U-shaped bracket. The hydraulic cylinder is electrically connected to the PLC controller, and a movable push rod is fixedly installed at the output end of the hydraulic cylinder, located at the bottom of the U-shaped bracket.
[0009] Preferably, positioning through holes are provided on both sides of the top of the U-shaped bracket, the positioning through holes penetrate the U-shaped bracket, and support limiting rods are fixedly installed on both sides of the top of the spray water collection pipe, the support limiting rods extend through the positioning through holes to the top of the U-shaped bracket.
[0010] Preferably, a positioning plate is fixedly installed on the inner walls of both sides of the plating bath, and a plating-aid hollow frame is movably installed on the top of the positioning plate, with handles fixedly installed on both sides of the top of the plating-aid hollow frame.
[0011] Preferably, a temperature sensor is fixedly installed on the inner wall of one side of the plating bath, and the temperature sensor is electrically connected to the PLC controller. A heating tube is fixedly installed inside the heating support box, and the heating tube is electrically connected to the PLC controller.
[0012] Preferably, a support base plate is fixedly installed at the bottom of the heating support box, and a plurality of support feet are evenly fixedly installed at the bottom of the support base plate. A drain pipe is fixedly installed on one side of the plating tank, and a control valve is movably installed at the top of the drain pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The fluxing tank for galvanizing parts significantly improves the fluxing solution's circulation and stirring capabilities through the circulation fluxing mechanism. In actual use, the circulation pump starts, drawing the fluxing solution from the bottom of the tank through the extraction pipe, transporting it to the spray collection pipe via the delivery telescopic pipe, and then spraying it back into the tank evenly from the nozzles. This circulation process keeps the fluxing solution flowing continuously within the tank, effectively overcoming the problem of uneven concentration in traditional static fluxing solutions. The nozzles are evenly distributed, and the spray collection pipe can cover a certain area, ensuring that the fluxing solution in all parts of the tank is fully mixed. The composition of the fluxing solution that comes into contact with different parts of the workpiece is consistent, avoiding inconsistent fluxing effects due to differences in fluxing solution concentration. This greatly improves the quality and uniformity of the galvanized layer, reduces thickness differences caused by fluxing issues, and increases the product qualification rate.
[0015] 2. This galvanizing bath, through the cooperation of a hydraulic cylinder, a movable push rod, and a support limit rod, enables the device to flexibly adjust the spray height. When the hydraulic cylinder is activated, its output end drives the movable push rod to rise and fall, which in turn pushes the spray collection pipe to move up and down. The support limit rod slides within the positioning through hole, ensuring stability and precision during the movement. By adjusting the height of the spray collection pipe, the nozzle can maintain a suitable distance and angle from the workpiece, ensuring that the galvanizing solution is sprayed onto the workpiece surface in the best condition, improving galvanizing efficiency and effect, and enhancing the device's adaptability to diverse workpieces.
[0016] 3. The fluxing bath for galvanizing parts features a positioning plate and a fluxing frame design, making workpiece placement more convenient. Placing the galvanized parts within the fluxing frame not only facilitates the overall placement of the workpiece into the fluxing bath, but the perforated structure also ensures that the fluxing solution fully contacts all surfaces of the workpiece, improving the fluxing effect. Simultaneously, the handle facilitates easy handling by operators. Furthermore, the temperature sensor and heating element, controlled by the PLC controller, can monitor and precisely adjust the temperature within the fluxing bath in real time, ensuring the fluxing process takes place in a suitable temperature environment. This provides favorable conditions for the fluxing reaction and further enhances the fluxing quality of the galvanized parts. Attached Figure Description

[0024] The circulating plating mechanism 4 includes a circulating pump 401. The circulating pump 401 is fixedly installed on one side of the plating tank 2 and is electrically connected to a PLC controller 3. A suction pipe 402 is fixedly installed on one side of the circulating pump 401, extending to the bottom of the plating tank 2. A liquid delivery telescopic pipe 403 is fixedly installed at the top of the circulating pump 401. A spray water collection pipe body 404 is fixedly installed on the side of the liquid delivery telescopic pipe 403 away from the circulating pump 401. Several spray nozzles 405 are evenly fixedly installed at the bottom of the spray water collection pipe body 404. A U-shaped bracket 406 is fixedly installed at the top of the plating tank 2, and a hydraulic cylinder 407 is fixedly installed at the top of the U-shaped bracket 406. The hydraulic cylinder 407 is connected to... The PLC controller 3 is electrically connected. A movable push rod 408 is fixedly installed at the output end of the hydraulic cylinder 407. The movable push rod 408 is located at the bottom end of the U-shaped bracket 406. Positioning through holes 409 are opened on both sides of the top end of the U-shaped bracket 406. The positioning through holes 409 penetrate the U-shaped bracket 406. Supporting limit rods 410 are fixedly installed on both sides of the top end of the spray water collection pipe 404. The supporting limit rods 410 extend through the positioning through holes 409 to the top end of the U-shaped bracket 406. The circulation pump 401 is started to extract the fluxing solution from the bottom of the fluxing tank 2 through the extraction pipe 402. The extracted fluxing solution flows into the spray water collection pipe 404 through the liquid delivery telescopic pipe 403 and is then sprayed out through the nozzles 405 evenly distributed at its bottom end.
[0025] Positioning plates 5 are fixedly installed on the inner walls of both sides of the plating bath 2. A plating filler frame 6 is movably installed on the top of the positioning plate 5. Handles 7 are fixedly installed on both sides of the top of the plating filler frame 6. A temperature sensor 8 is fixedly installed on the inner wall of one side of the plating bath 2. The temperature sensor 8 is electrically connected to the PLC controller 3. A heating tube 9 is fixedly installed inside the heating support box 1. The heating tube 9 is electrically connected to the PLC controller 3. A support base plate 10 is fixedly installed at the bottom of the heating support box 1. Several support feet 11 are evenly fixedly installed at the bottom of the support base plate 10. A drain pipe 12 is fixedly installed on one side of the plating bath 2. A control valve 13 is movably installed at the top of the drain pipe 12. The heating tube 9 is activated to heat the plating solution. The temperature of the plating solution in the plating bath 2 is monitored in real time by the temperature sensor 8.
[0026] Working Principle: When auxiliary plating is required, first, the device is stably placed in the desired location, and an external power supply is connected to power the equipment. Then, the workpiece to be auxiliated is placed into the auxiliary plating frame 6, and the frame 6 is placed on the positioning plate 5, placing it in the auxiliary plating tank 2. Next, an appropriate amount of auxiliary plating solution is added to the tank 2, and the heating element 9 is activated to heat the solution. The temperature of the auxiliary plating solution in the tank 2 is monitored in real time by a temperature sensor 8, and the data is transmitted to the PLC controller 3. The temperature sensor 8 is a CWF2 type. In the PT100 model, if the temperature is lower than the set value, the PLC controller 3 immediately activates the heating tube 9 inside the heating support box 1 to heat the solution. When the temperature reaches the set range, the heating tube 9 stops working to maintain a stable temperature for the fluxing solution. A stable temperature environment helps the fluxing solution fully remove oxides from the workpiece surface and enhance wettability, ensuring the quality and adhesion of the zinc plating layer. Subsequently, the circulation pump 401 is activated to extract the fluxing solution from the bottom of the fluxing tank 2 through the extraction pipe 402. Because the fluxing solution at the bottom of the tank has a low concentration and complex composition due to workpiece reactions and sedimentation, extracting this liquid effectively promotes overall mixing. The extracted fluxing solution flows into the spray collection pipe 404 through the infusion telescopic pipe 403, and then returns to the fluxing tank 2 in the form of spraying through the evenly distributed nozzles 405 at its bottom. The spraying direction and range of the nozzles 405 cover the entire tank, forming a downward liquid flow impact, which promotes the circulation of the fluxing solution in the tank. This circulation continuously... To prevent the stratification of the flux concentration, the flux components in the pool are quickly and evenly mixed, ensuring that the flux composition in contact with all parts of the galvanized parts is consistent during the fluxing process, thereby improving the uniformity of the fluxing effect. The circulation pump 401 adopts an IS-type single-stage single-suction centrifugal circulation pump. At the same time, the hydraulic cylinder 407 is activated to push the movable push rod 408 to move up and down. The movable push rod 408 drives the spray water collection pipe 404 to move up and down. The support limit rod 410 at the top of the spray water collection pipe 404 slides in the positioning through hole 409 at the top of the U-shaped bracket 406. By precisely controlling the extension and retraction of the hydraulic cylinder 407, the height of the nozzle 405 can be precisely adjusted so that the flux is sprayed onto the workpiece surface in the best condition, adapting to the fluxing requirements of different workpieces. When the flux has been used for a period of time, it needs to be replaced. The operator opens the control valve 13 at the top of the drain pipe 12. Under the action of gravity, the old flux in the fluxing pool 2 is discharged through the drain pipe 12, and then new flux is injected.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
