Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning technology for air pipelines used in paint spraying, and more specifically, to a tooling for cleaning oil and water plugs in paint spraying pipelines for wheels. Background Technology
[0002] Traditional wheel painting techniques, such as painting in black, gunmetal gray, white, red, blue, and champagne gold, often result in incomplete cleaning with thinner when switching between colors. This residue from the original paint mixes with the new paint, causing color differences. Furthermore, mixing paints with different compositions can lead to severe orange peel effects after curing due to varying curing rates of additives, resulting in rework and repairs. Therefore, it is necessary to inspect and replace the paint spraying lines to prevent color mixing and subsequent appearance defects that affect the pass rate.
[0003] From May to October, the air humidity is high, especially on rainy days, when the relative humidity can reach 100% RH. Although there are oil and water filters, the oil and water content in the compressed air pipeline often exceeds the processing and filtration peak, and it is impossible to avoid a small amount of oil and water accumulating in the compressed air pipeline. Because the paint needs to be delivered to the paint gun through the paint hose during painting, and then mixed with compressed air before being sprayed onto the wheel products from the nozzle, this results in oil and water mixed in with the compressed air and paint when the products are painted. This causes pits, oil spots, and water spots to appear after the products are baked and cured, resulting in paint rework. Assuming that 4 pieces are painted per minute, a whole 18-20KG can of paint takes about 20-25 minutes to paint, and about 80-100 products are at risk of being reworked due to color difference and oil and water contamination. Therefore, it is also necessary to clean the oil and water in the compressed air pipeline. Summary of the Invention
[0004] To solve the above problems, the technical solution adopted in this application is a tooling for a wheel paint spraying pipeline cleaning oil and water plug, which includes five cleaning oil and water plugs fixedly connected by a support rod. The cleaning oil and water plugs are arranged from front to back as a positioning plug, a first collecting plug, a scraping plug, a second collecting plug, and a pressurizing plug. The cleaning oil and water plugs are arranged coaxially under the fixation of the support rod, and the central axis of each cleaning oil and water plug coincides with the central axis of the support rod. The positioning plug is a hemisphere that protrudes forward, the first collecting plug and the second collecting plug are hollow hemispheres that protrude backward, and the outer diameter of the hollow hemisphere of the first collecting plug is greater than or equal to the diameter of the target pipeline. The scraping plug is a hollow hemisphere that protrudes forward, and the pressurizing plug is a hemisphere that protrudes backward, and the diameter of the hemisphere of the pressurizing plug is smaller than the diameter of the target pipeline.
[0005] Optionally, the positioning plug, the first collecting plug, the scraping plug, the second collecting plug, the pressurizing plug, and the support rod are all made of silicone-free and glycerin-free rubber.
[0006] Optionally, the hollow hemispherical wall thickness of the first and second collecting plugs remains unchanged.
[0007] Optionally, the wall thickness of the hollow hemisphere of the scraper plug gradually decreases from front to back.
[0008] Optionally, a countersunk groove is provided at the center of the top of the hemisphere of the positioning plug, and a hemispherical reinforcing rib protruding rearward is fixed behind the hemisphere of the positioning plug, the diameter of the hemispherical reinforcing rib being larger than the diameter of the countersunk groove.
[0009] Optionally, a spherical groove is provided at the center of the top of the hemisphere of the booster plug.
[0010] Optionally, a connecting reinforcement plug is provided between the scraping plug and the second collecting plug. The connecting reinforcement plug is a sphere and is made of silicone-free and glycerin-free rubber.
[0011] Optionally, the diameters of the hemisphere of the positioning plug and the sphere of the connecting reinforcement plug are both less than or equal to the diameter of the target pipeline, while the outer diameter of the hollow hemisphere of the scraping plug and the outer diameter of the hollow hemisphere of the second collecting plug are greater than or equal to the diameter of the target pipeline.
[0012] The beneficial effects of the wheel paint spraying pipeline clear oil plug tool provided in this application are as follows: (1) The oil and water in the wheel painting pipeline is cleaned by the positioning plug, the first collecting plug, the scraping plug, the second collecting plug and the booster plug connected in sequence. The first collecting plug first collects and scrapes the residual oil and water in the pipeline. The oil and water are collected into the hollow hemisphere of the first collecting plug. The scraping plug contacts the inner wall of the pipe and scrapes the oil and water points on the pipe wall. The oil and water scraped off by the scraping plug is collected by the second collecting plug. The five cleaning plugs fixedly connected by the support rod move in the target cleaning pipeline under the power of compressed air. The compressed air flow from the pipeline air inlet passes through the gap between the hemisphere of the booster plug and the pipe wall, and the pressure increases, which drives the plug body at the front of the booster plug to move forward. When the cleaning plug leaves the target cleaning pipeline, one cleaning process is completed. (2) In seasons with high humidity in the working environment, the wheel paint spraying pipeline cleaning water plug tooling provided in this application effectively reduces the rework of vehicle products due to paint defects caused by oil and water spots in the paint spraying pipeline, and reduces the color difference caused by residual paint in the pipeline to the new paint after paint replacement. The tooling is an integrated design, and the mold opening can enable mass production. It is easy to operate, quick to clean, and has a good cleaning effect. Attached Figure Description

Detailed Implementation
[0015] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0016] This application provides a tooling for a clear oil and water plug in a wheel paint spraying pipeline, such as... Figures 1-6 As shown, it includes five clean oil and water plugs fixedly connected by a support rod 6. The clean oil and water plugs are arranged from front to back as positioning plug 1, first collection plug 2, scraping plug 4, second collection plug 3 and pressurizing plug 5. The clean oil and water plugs are arranged coaxially under the fixation of the support rod 6, and the central axis of each clean oil and water plug coincides with the central axis of the support rod 6. The coincidence position of each central axis is shown in the schematic diagram of the center position of the central axis coincidence 9. Positioning plug 1 is a hemisphere protruding forward, first collecting plug 2 and second collecting plug 3 are hollow hemispheres protruding backward, and the outer diameter of the hollow hemisphere of first collecting plug 2 is greater than or equal to the diameter of the target pipeline, scraping plug 4 is a hollow hemisphere protruding forward, and pressurizing plug 5 is a hemisphere protruding backward, and the diameter of the hemisphere of pressurizing plug 5 is smaller than the diameter of the target pipeline.
[0017] The oil and water in the wheel paint spraying pipeline is cleaned by sequentially connecting the positioning plug 1, the first collecting plug 2, the scraping plug 4, the second collecting plug 3, and the booster plug 5. The first collecting plug 2 first collects and scrapes away the residual oil and water in the pipeline. The oil and water are collected and enter the hollow hemisphere of the first collecting plug 2. The scraping plug 4 contacts and scrapes the oil and water points on the inner wall of the pipeline. The oil and water scraped off by the scraping plug 4 is collected by the second collecting plug 3. The five cleaning plugs, which are fixedly connected by the support rod 6, move in the target cleaning pipeline under the power of compressed air. After the compressed air airflow from the pipeline air inlet passes through the gap between the hemisphere of the booster plug 5 and the pipeline wall, the pressure increases, which drives the plug body at the front of the booster plug 5 to move forward. When the cleaning plug leaves the target cleaning pipeline, one cleaning process is completed. Then the plug body is reversed 180° in the first direction and inserted into the pipeline again. The second cleaning is carried out by the scraping of the plug body driven by compressed air, thus achieving a complete cleaning cycle.
[0018] In seasons with high humidity in the working environment, the wheel paint spraying pipeline cleaning plug tooling provided in this application effectively reduces paint defects and rework caused by oil and water droplets in the paint spraying pipeline, and reduces color differences caused by residual paint in the pipeline after paint replacement. The tooling can be mass-produced after mold making, is easy to operate, and is quick and effective to clean.
[0019] In this embodiment, the material of the oil-water plug fixture for the wheel paint spraying pipeline is silicone-free soft rubber, and the color is white or red. After cleaning, it is easier to visually inspect whether there is any oil, water, or paint residue adhering to the inner wall of the compressed air pipeline, especially making black and gray residue more obvious. Inside the pipeline, the contaminants adhering to the pipeline wall are wiped away and pushed forward by the compressed air pressure.
[0020] In another embodiment of this application, the positioning plug 1, the first collecting plug 2, the scraping plug 4, the second collecting plug 3, the pressurizing plug 5, and the support rod 6 are all made of silicone-free and glycerin-free rubber. Silicone-free and glycerin-free rubber has the characteristics of not shedding slag or chips, having a good scraping effect on the inner wall of the pipe, and not damaging the walls of the compressed air pipe and the paint delivery pipe. It will not contaminate the pipeline, nor damage the plastic air delivery pipe and paint delivery pipe, and can be used with a thinner to effectively clean the paint delivery pipe.
[0021] In another embodiment of this application, such as Figure 2 As shown, the hollow hemispherical wall thickness of the first collecting plug 2 and the second collecting plug 3 remains unchanged. The first collecting plug 2 and the second collecting plug 3 are mainly used to collect oil and water, and the constant wall thickness of their hollow hemispheres is beneficial for providing the maximum collection capacity within a given design size.
[0022] In another embodiment of this application, such as Figure 2As shown, the wall thickness of the hollow hemisphere of the scraper plug 4 gradually decreases from front to back. The hollow hemisphere of the scraper plug 4 is used to reduce the pushing resistance. The scraper plug 4 is mainly used to scrape the oil and water points on the pipe wall by contacting the inner wall of the pipe.
[0023] In another embodiment of this application, such as Figures 2-3 As shown, a countersunk groove 7 is provided at the center of the top of the hemisphere of the positioning plug 1, and a hemispherical reinforcing rib 10 protruding rearward is fixed behind the hemisphere of the positioning plug 1. The diameter of the hemispherical reinforcing rib 10 is larger than the diameter of the countersunk groove 7.
[0024] In another embodiment of this application, such as Figure 2 and Figure 4 As shown, a spherical groove 8 is provided at the center of the top of the hemisphere of the booster plug 5. In this embodiment, the booster plug 5 itself also serves to push the oil and water plug tool of the wheel paint spraying pipeline forward, and therefore the spherical groove 8 is provided to receive the power of compressed air.
[0025] In another embodiment of this application, such as Figures 1-4 As shown, a connecting reinforcing plug 11 is provided between the scraping plug 4 and the second collecting plug 3. The connecting reinforcing plug 11 is a sphere made of silicone-free and glycerin-free rubber. During use, the scraping plug 4 and the second collecting plug 3 are typically in a compressed and deformed state. To prevent interference between the scraping plug 4 and the second collecting plug 3, the support rod 6 between them is relatively long. To increase the support strength of the support rod 6 at this position and prevent the front and rear parts from stacking together after compressed air compression, thus better maintaining the arrangement of the scraping plug 4 and the second collecting plug 3, the connecting reinforcing plug 11 is provided at this position. Besides reinforcing the support effect of the support rod 6, the connecting reinforcing plug 11 also quickly guides the oil and water scraped off by the scraping plug 4 into the rounded groove of the second collecting plug 3 for storage.
[0026] In another embodiment of this application, the diameters of the hemisphere of the positioning plug 1 and the sphere of the connecting reinforcing plug 11 are both less than or equal to the diameter of the target pipeline, while the outer diameter of the hollow hemisphere of the scraping plug 4 and the outer diameter of the hollow hemisphere of the second collecting plug 3 are greater than or equal to the diameter of the target pipeline.
[0027] In this embodiment, the hemispherical radius of the positioning plug 1 is 8.1 mm, with a 5 mm diameter countersunk groove 7 at the top center and a depth of 5 mm. The radius of the hemispherical reinforcing rib 10 is 4.7 mm. The outer radius of the first collecting plug 2 is 10.5 mm, and the wall thickness is 1.5 mm. The outer radius of the scraping plug 4 is 9 mm, with a maximum wall thickness of 2.46 mm and a minimum wall thickness of 0.74 mm. The outer radius of the second collecting plug 3 is 8.5 mm, and the wall thickness is 1.5 mm. The outer radius of the pressure-boosting plug 5 is 6.7 mm, the radius of the spherical groove 8 is 2.4 mm, and the radius of the support rod 6 is 1.5 mm. The radius of the connecting reinforcing plug 11 is 5 mm. This design is suitable for cleaning pipelines with an inner diameter of 16.2 mm to 17 mm.
[0028] The above is only a design example. The specific parameters of each oil filler plug and support rod should be flexibly adjusted according to the different diameters of the paint spraying pipes during actual production.
[0029] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
