Description

Technical Field

[0001] This utility model belongs to the technical field of polishing devices, specifically relating to a three-phase foam cavitation jet polishing device. Background Technology

[0002] Polishing is a commonly used process in product finishing. It significantly improves the smoothness and aesthetics of workpieces, making their surfaces smoother and brighter. This not only enhances the product's visual appeal but also increases its overall texture and value. In mold manufacturing, polished mold cavities are smoother, facilitating demolding during production, thus improving efficiency and reducing cycle time. Polished surfaces sometimes require subsequent treatments such as electroplating to further enhance the wear and corrosion resistance of the mold or workpiece, extending its lifespan. For certain products, such as optical lenses and precision instruments, extremely high surface finish is required. Polishing meets these specific functional needs, ensuring product performance and precision. Furthermore, in mold manufacturing, polishing improves the accuracy of mold mating surfaces, preventing burrs and other issues during production, ensuring smooth product manufacturing.

[0003] In the actual polishing process, the applicant found that most polishing methods still rely on manual polishing, which consumes a lot of labor costs and produces inconsistent polishing quality. Furthermore, manual polishing is inherently dangerous and is not suitable for batch polishing because its efficiency cannot be guaranteed. Utility Model Content

BRIEF DESCRIPTION OF DRAWINGS

[0015] The utility model can be further illustrated by the non-limiting embodiments shown in the drawings.

[0016] Figure 1 It is a structure schematic view of a three-phase foam cavitation jet polishing device embodiment of the utility model.

[0017] The main element symbols are explained as follows:

[0018] Mixing cylinder 1; agitator 2; diaphragm pump 3; booster pump 4; foam generator 5; flow meter 6; pressure gauge 7; nozzle 8; container 9; workpiece 10; clamp 11; output pipe 12. DETAILED DESCRIPTION

[0019] In order for those skilled in the art to better understand the present application, the technical solutions of the present application are further described below in conjunction with the drawings and examples.

[0020] As shown in Figure 1 The three-phase foam cavitation jet polishing device of the present application comprises a mixing cylinder 1, the mixing cylinder 1 is provided with an agitator 2, the output end of the mixing cylinder 1 is connected with a diaphragm pump 3, the output end of the diaphragm pump 3 is connected with a booster pump 4, the output end of the booster pump 4 is connected with a foam generator 5, and the output end of the foam generator 5 is connected with an output pipe 12.

[0021] The input end of the mixing cylinder 1 is connected with a container 9, the inner bottom of the container 9 is provided with a clamp 11, and the clamp 11 clamps a workpiece 10.

[0022] Preferably, the output pipe 12 is provided with a flow meter 6 and a pressure gauge 7, which can observe the flow and pressure of the device in real time. In fact, the selection of monitoring instruments installed on the output pipe 12 can also be considered according to the specific circumstances.

[0023] Preferably, the output end of the output pipe 12 is provided with a nozzle 8, which can strengthen the impact force and expand the impact range. In fact, the selection of the specifications and models of the nozzle 8 and the installation method can also be considered according to the specific circumstances, such as the adjustment of the angle.

[0024] Preferably, the mixing cylinder 1 is filled with a mixture of hydrocarbon carrier liquid, abrasive particles, and dispersant. This design allows the hydrocarbon carrier liquid to serve as the base of the polishing liquid, providing good lubrication and cooling effects, reducing friction and heat generation during polishing, and protecting the workpiece surface from damage. At the same time, the hydrocarbon carrier liquid can effectively carry abrasive particles, ensuring uniform distribution and contact of abrasive particles on the workpiece surface during polishing, improving polishing efficiency. Secondly, abrasive particles are the key component of the polishing liquid, directly determining the polishing effect. Under the carrying of the hydrocarbon carrier liquid, abrasive particles can uniformly act on the workpiece surface, removing surface defects and dirt through physical friction and chemical action, achieving a smooth and bright effect on the workpiece surface. In addition, the hardness and particle size of abrasive particles can be adjusted according to specific polishing requirements to meet the polishing requirements of different materials and surface conditions. Finally, the dispersant plays a crucial role in the polishing liquid, effectively dispersing abrasive particles in the hydrocarbon carrier liquid, preventing abrasive particle agglomeration and precipitation, and maintaining the stability of the polishing liquid and the durability of the polishing effect. At the same time, the dispersant can improve the rheological properties of the polishing liquid, making it better adapt to the shape and changes of the workpiece surface during polishing, improving the precision and uniformity of polishing. Moreover, since the hydrocarbon carrier liquid, abrasive particles, and dispersant are relatively environmentally friendly and safe materials, this polishing liquid does not produce harmful substances during use, and is friendly to the environment and the health of operators. In fact, the selection of the mixed liquid can also be considered according to specific circumstances.

[0025] Preferably, the horizontal placement position of the container 9 is higher than that of the mixing cylinder 1. This design facilitates the backflow of the polishing liquid. In fact, the horizontal placement position of the container 9 can also be considered according to specific circumstances.

[0026] In this embodiment, when using a three-phase foam cavitation jet polishing device, the polishing mixed liquid is added to the mixing cylinder 1, and then the stirrer 2 is started to stir, so that the mixed liquid is mixed more uniformly and prevents sedimentation. Then the diaphragm pump 3 is started, which sucks air and mixed liquid into the booster pump 4 through the pipeline. The booster pump 4 is connected to the foam generator 5, which obtains energy through impeller rotation. When the liquid pressure at the inlet of the impeller decreases to the saturation vapor pressure of the liquid at that temperature, the liquid begins to vaporize, forming cavities. The pressure is adjusted by controlling the booster pump 4 according to actual requirements. The mixed liquid containing abrasive particles, cavities, and hydrocarbon liquid is sprayed at high speed through the nozzle 8 to the surface of the workpiece 10 fixed in the polishing container 9 by the clamp 11. The polished mixed liquid is backflowed to the polishing liquid mixing cylinder 1 through the pipeline below the polishing container 9 for recycling, achieving the purpose of circulation.

[0027] The three-phase foam cavitation polishing mechanism is further illustrated as follows: when the liquid is compressed into the foam generator and the local pressure is reduced to below the vapor pressure of the liquid, cavitation bubbles are formed; with the high-speed flow of the liquid, the mixed liquid containing a large number of bubbles is sprayed from the nozzle; the cavitation bubbles collapse rapidly when the pressure is restored, releasing a large amount of energy, generating strong micro-jet impact; these impact waves exert high-energy impact on the workpiece surface, and generate instantaneous high temperature and high pressure in a small range, promoting the removal of the material and the improvement of the micro-morphology; in addition, abrasive particles flow with the liquid and are sprayed at high speed to the workpiece surface, cutting the material in the impact process, forming small pits and grooves, thereby improving the surface precision; the cavitation effect enhances the friction and impact of the mixed liquid on the workpiece surface, effectively improving the removal rate; compared with the traditional abrasive water jet, the three-phase foam cavitation jet has enhanced cavitation effect and small flow entrainment, and the material is removed in cavitation.

Any person skilled in the art can modify or change the above examples without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should be covered by the claims of the utility model.
