Abstract
Description
Technical Field
[0001] This utility model belongs to the field of galvanizing equipment, and in particular to a galvanizing device for sheet metal surfaces. Background Technology
[0002] Distribution cabinets are typically rectangular box structures assembled from plates and frames. To improve their corrosion resistance, they are usually galvanized. The conventional galvanizing method is hot-dip galvanizing, which involves immersing the distribution cabinet in molten zinc (approximately 450°C) to form a zinc-iron alloy layer. For details, please refer to the invention patent application CN202410871131.0, which discloses a surface galvanizing device for power distribution boxes. This device hot-dip galvanizes the entire distribution cabinet. However, the overall size of the distribution cabinet is relatively large, making clamping and transportation inconvenient. Only one distribution cabinet can be galvanized at a time, resulting in low galvanizing efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a zinc plating device for sheet metal, which can zinc plating the raw material sheet metal of the power distribution cabinet and improve the zinc plating efficiency.
[0004] To solve the above problems, the technical solution adopted by this utility model is: a galvanizing device for sheet metal surfaces, including a tank and a support assembly, wherein the support assembly is connected to a lifting assembly.
[0005] The support assembly includes a horizontal support plate located inside the pool. The support plate has multiple through holes. Multiple parallel limiting frames are provided on the upper surface of the support plate. A positioning gap is provided between two adjacent limiting frames, and end limiting members are provided between the two ends of two adjacent limiting frames.
[0006] A drive blade is provided at one end of the inner cavity of the pool, and the drive blade is connected to a drive motor through a transmission shaft. The drive motor is located outside the pool.
[0007] Furthermore, the lifting assembly includes a first hydraulic cylinder.
[0008] Furthermore, a support is provided above the pool body, the first hydraulic cylinder is vertically installed on the support, and the lower end of the first hydraulic cylinder is connected to a lifting frame. Each end of the support plate is provided with a set of vertical connecting rods, and the connecting rods are fixedly connected to the lifting frame.
[0009] Furthermore, the lifting frame is provided with multiple vertical guide columns, which penetrate the support and slide in cooperation with the support.
[0010] Furthermore, a slag removal assembly is provided inside the pool.
[0011] Furthermore, the slag removal assembly includes a slag scraping assembly and a filter tank, the filter tank being disposed at one end of the inner cavity of the tank and connected to a lifting mechanism.
[0012] Furthermore, the slag scraping assembly includes a horizontally arranged support rail, a movable frame is arranged on the support rail, and a slag scraping plate is arranged on the movable frame.
[0013] Furthermore, the lifting mechanism is a second hydraulic cylinder.
[0014] The beneficial effects of this utility model are: when using this utility model, each plate is placed in a positioning gap. Since multiple positioning gaps are set, multiple plates can be placed. Each plate occupies very little space, making it easier to move the plates. Moreover, the number of plates placed each time can prepare more than one distribution cabinet, which increases the number of plates galvanized each time, thereby improving the galvanizing efficiency.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] The plate surface galvanizing device of this utility model, such as Figures 1 to 3 As shown, the system includes a pool body 1 and a support assembly, with a lifting assembly connected to the support assembly. The pool body 1 is a rectangular parallelepiped and can be made of high-temperature resistant metal. The pool body 1 holds molten zinc and is equipped with a heating element inside to heat and maintain the temperature of the galvanizing solution, preventing it from becoming too cold. To precisely control the temperature inside the pool body 1, a thermocouple can be installed to detect the temperature of the galvanizing solution. When the temperature of the galvanizing solution exceeds a set value, the heating element heats the solution, ensuring it remains at a suitable temperature.
[0021] The support assembly is used to support and position the sheet metal, and the lifting assembly is used to move the support assembly up and down, thereby immersing the sheet metal in the galvanizing solution and removing it from the galvanizing solution. To achieve galvanizing of multiple sheet metals at once, the support assembly of this invention includes a horizontal support plate 2. The support plate 2 is made of a metal plate of a certain thickness and has a high bearing capacity. The support plate 2 is located inside the pool body 1 and has multiple through holes for the galvanizing solution to pass through. Multiple parallel limiting brackets 3 are provided on the upper surface of the support plate 2. The limiting brackets 3 can be assembled from profiles, rods, etc., and their bottoms are welded to the support plate 2. A positioning gap is provided between adjacent limiting brackets 3, the width of which is slightly larger than the thickness of the sheet metal to be galvanized, ensuring that the sheet metal to be galvanized can be placed within the positioning gap. An end-limiting member 4 is provided between the two ends of two adjacent limiting uprights 3. The end-limiting member 4 is used to limit the two ends of the plate. The end-limiting member 4 can be made of metal rods or profiles, etc., and the two ends of the end-limiting member 4 can be welded to the limiting uprights 3. The limiting uprights 3, the end-limiting members 4, and the support plate 2 can provide stable support and limit the plate, preventing the plate from moving outside the positioning distance.
[0022] To improve galvanizing efficiency by promoting the flow of the galvanizing solution, a drive blade 5 is installed at one end of the inner cavity of the tank body 1. The drive blade 5 is connected to a drive motor 7 via a transmission shaft 6, which is located outside the tank body 1. The transmission shaft 6 horizontally penetrates the side wall of the tank body 1, and there is a good seal between the transmission shaft 6 and the side wall of the tank body 1 to prevent leakage of the galvanizing solution. When the drive motor 7 drives the transmission shaft 6 to rotate, the transmission shaft 6 drives the drive blade 5 to rotate, and the drive blade 5 can then promote the flow of the galvanizing solution. The flow direction of the galvanizing solution is consistent with the length direction of the positioning spacing.
[0023] When using this invention, the support plate 2 is raised above the galvanizing solution surface. Then, each sheet to be galvanized is placed into its designated positioning space. The lower edge of the sheet is supported by the support plate 2, the two sides by the limiting brackets 3, and the two ends by the end limiting members 4, ensuring stability within the positioning space. The lifting assembly then lowers the support plate 2 and the sheet until they are fully immersed in the galvanizing solution. During galvanizing, the drive motor 7 is activated, rotating the drive blades 5. The drive blades 5 propel the galvanizing solution, allowing it to react fully and quickly with the sheet. After galvanizing, the lifting assembly moves the support plate 2 and the sheet upwards to above the galvanizing solution surface. Once the galvanizing solution on the sheet surface has cooled, the sheet is removed, completing the galvanizing process.
[0024] In this invention, the sheet metal is galvanized. Due to the small size of the sheet metal, multiple sheets can be galvanized at once, and the number of sheets galvanized each time is sufficient to manufacture more than one distribution cabinet, thereby improving galvanizing efficiency. After galvanizing, the sheet metal is then assembled into the distribution cabinet body.
[0025] In this invention, the lifting assembly includes a first hydraulic cylinder 8. Specifically, a bracket 9 is provided above the pool body 1, and the first hydraulic cylinder 8 is vertically mounted on the bracket 9. The piston rod of the first hydraulic cylinder 8 faces downward, and the lower end of the first hydraulic cylinder 8 is connected to a lifting frame 10. The lifting frame 10 is I-shaped and can be welded from profiles. The center of the first hydraulic cylinder 8 and the lifting frame 10 are connected, which helps to balance the force on the lifting frame 10. A set of vertical connecting rods 11 is provided at each end of the support plate 2, and the connecting rods 11 are fixedly connected to the lifting frame 10. The lower end of the connecting rod 11 can be welded to the support plate 2, and the upper end of the connecting rod 11 can pass through the lifting frame 10 and have a clearance fit with the lifting frame 10. The upper end of the connecting rod 11 can be provided with an external thread section, and a nut is provided on the external thread section. The nut is located on the upper surface of the lifting frame 10, which can adjust the distance between the support plate 2 and the lifting frame 10, that is, adjust the height of the support plate 2.
[0026] To improve the stability of the lifting frame 10 during lifting, multiple vertical guide columns 12 are installed on the lifting frame 10. The guide columns 12 pass through the support 9 and slide in cooperation with the support 9. The guide columns 12 serve to guide and position, ensuring that the lifting frame 10 moves vertically upward or downward without tilting.
[0027] The zinc plating solution uses metallic zinc. When the liquid surface comes into contact with air, it easily reacts with oxygen in the air to form zinc oxide, which then forms zinc oxide dross on the surface of the zinc plating solution. To remove this dross, this invention includes a dross removal component inside the pool body 1. After one or more zinc plating cycles, the dross can be removed using the dross removal component.
[0028] The slag removal assembly can be a dredging device that uses a mesh container to remove floating slag. In a preferred embodiment, the slag removal assembly includes a scraper assembly and a filter tank 13. The filter tank 13 is located at one end of the inner cavity of the pool body 1 and is connected to a lifting mechanism 14. The scraper assembly can scrape the floating slag on the surface of the galvanizing solution to move it. The filter tank 13 is immersed in the galvanizing solution. During slag removal, the scraper assembly scrapes the floating slag on the surface of the galvanizing solution to the top of the filter tank 13. Then, the lifting mechanism 14 pulls the filter tank 13 slowly upwards to the surface of the galvanizing solution, allowing the filter tank 13 to carry the floating slag out. After the temperature of the filter tank 13 decreases, the floating slag in the filter tank 13 can be scraped off and cleaned using tools such as scrapers. Then, the filter tank 13 is immersed in the galvanizing solution again.
[0029] During galvanizing, the slag scraper assembly is located at one end of the inner cavity of the pool body 1, which will not affect the support plate 2 or the entry and exit of the plate into the galvanizing solution.
[0030] In this invention, the slag scraping assembly includes a horizontally arranged support rail 15, a movable frame 16 mounted on the support rail 15, and a slag scraper 17 mounted on the movable frame 16. A conventional translation drive mechanism can be installed on the movable frame 16, utilizing a rack on the support rail 15 and a moving motor on the movable frame 16. The main shaft of the moving motor has a gear, which meshes with the rack. When the moving motor rotates, it drives the movable frame 16 to move along the support rail 15. Alternatively, the movable frame 16 can also be driven by a commonly used drive mechanism such as a motor-driven screw and nut mechanism or a hydraulic cylinder. The lower side of the slag scraper 17 extends into the galvanizing solution. When the movable frame 16 moves the slag scraper 17 towards the filter tank 13, it scrapes the slag on the surface of the galvanizing solution to the top of the filter tank 13.
[0031] In this utility model, the lifting mechanism 14 is a second hydraulic cylinder, and the lower end of the second hydraulic cylinder is connected to the filter tank 13 through a connecting column.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
