Description

Technical Field

[0001] The present application relates to the technical field of acrylic material processing, and in particular to a polishing process and device for acrylic material. Background Art

[0002] Acrylic materials are widely used in industry and daily life due to their excellent transparency and mechanical properties. However, acrylic materials often leave matte and knife marks on the surface of parts after processing, which not only affects the appearance but also the functionality of the product. In order to achieve higher transparency and finish requirements (such as Ra0.2-Ra0.4), various polishing processes such as flame polishing, cloth wheel polishing and diamond polishing are commonly used in the market. Although these traditional polishing methods can partially remove the matte and knife marks, they generally have certain limitations.

[0003] Existing acrylic material polishing technologies mainly include flame polishing, cloth wheel polishing and diamond polishing. Among them, flame polishing is to melt the acrylic surface at high temperature and then cool it quickly to achieve a smooth effect; cloth wheel polishing is to use soft cloth with abrasives to rub the acrylic surface to gradually remove surface defects; and diamond polishing is to attach diamond particles to a high-speed rotating tool to finely process the acrylic surface through high pressure and high speed. Although these methods have their own characteristics, they all have some common problems in practical applications.

[0004] The above-mentioned traditional polishing methods are often difficult to meet the requirements of transparency and smoothness in practical applications, especially when dealing with parts with complex shapes and special structures. In addition, these methods have high requirements on the environment and equipment, the operation process is relatively complicated, and they are prone to problems such as stress cracks, resulting in unstable polishing effects and difficult to ensure product quality. Therefore, there is an urgent need for a new acrylic material polishing process that can simplify the operation process, reduce costs, and reduce the impact on the environment while ensuring transparency and smoothness. Summary of the invention

[0005] The purpose of this application is to overcome the above technical problems and provide a polishing process and device for acrylic materials. A polishing process for acrylic material, comprising the following steps: (a) Rough polishing: The workpiece to be polished should be placed steadily. Small workpieces should be fixed to reduce workpiece displacement during the polishing process, resulting in operational defects. Use 1000-grit sandpaper to remove knife marks along one direction on the surface of the part, and polish multiple positions alternately; (b) Preliminary cleaning: Use clean water to clean the parts after rough polishing to remove dirt and oil on the surface of the parts; (c) Fine polishing: The workpiece to be polished should be placed stably. Small workpieces should be fixed to reduce workpiece displacement during the polishing process, which may cause defects. Use 3000-grit sandpaper or polishing paste to fine-polish the surface of the part in one direction for 2-5 minutes. For the cavity position, use a polishing pen to clamp a cotton swab or bamboo stick to fine-polish the cavity position for 1-2 minutes. Polish multiple positions alternately. (d) Secondary cleaning: Use clean water to clean the parts after fine polishing to remove dirt and oil on the surface of the parts; (e) Steam polishing: Hang the workpiece to ensure that it does not shake, reduce the displacement of the workpiece during the polishing process and cause work defects. Protect yourself before the operation, use headlight repair solution and steam spray pot to polish the surface, through holes and tooth holes of the parts for 1-2 minutes, and repeat this action 2-3 times, alternately polish multiple positions to reduce the impact on the size of the parts; (f) Final cleaning: Use clean water to clean the parts after steam polishing to remove dirt and oil on the surface of the parts; in addition, before the steam polishing step, use infrared preheating equipment to preheat the workpiece to be polished to reduce the risk of stress cracks generated during the polishing process.

[0006] By adopting the above technical solution, the polishing process of acrylic materials can effectively remove the matte and knife marks on the surface of parts, making the parts transparent and smooth with the requirements of Ra0.2-Ra0.4. The process is easy to operate, does not require special training, reduces production costs, is environmentally friendly, and does not require special equipment support. In particular, in the steam polishing step, the surface of the part is slightly melted and re-cooled by steam, which not only improves the quality and stability of the product, but also reduces the dimensional changes caused by long-term polishing, ensuring the accuracy of the parts.

[0007] Preferably, the 1000-grit sandpaper used in the rough polishing step is wet sandpaper and is kept wet during the rough polishing process to improve the effect of removing knife marks; and after the rough polishing step, the surface of the workpiece is wiped dry with a soft rag to better observe the polishing effect.

At the same time, using a soft cloth to wipe the workpiece surface dry helps to better observe the polishing effect, timely discover and deal with possible problems, and ensure the smooth progress of subsequent processes.

[0009] Preferably, at least one of the 3000-mesh sandpaper or polishing paste used in the fine polishing step is a composite material containing fine particles to enhance the polishing effect and smoothness; and during the fine polishing process, a pneumatic polishing pen can be used in conjunction with a low-speed rotating head to reduce pressure on the workpiece and reduce damage to the workpiece surface.

[0010] By adopting the above technical solution, the use of composite materials containing fine particles as 3000-grit sandpaper or polishing paste in the fine polishing step can significantly enhance the polishing effect and smoothness, making the surface of the parts smoother and more delicate. At the same time, the use of a pneumatic polishing pen with a low-speed rotating head during the fine polishing process can effectively reduce the pressure on the workpiece and reduce the surface damage of the workpiece caused by excessive pressure, thereby ensuring the polishing quality and workpiece integrity.

[0011] Preferably, during the initial cleaning and secondary cleaning steps, check whether there is any residual sand or abrasive on the surface of the parts, and use a brush to gently remove the residue to ensure thorough cleaning; and after each cleaning, use compressed air to blow the surface of the workpiece to further remove moisture and residue.

[0012] By adopting the above technical solution, the residual sand or abrasives in the rough polishing and fine polishing process can be effectively removed to ensure that the surface of the parts is thoroughly cleaned. At the same time, using compressed air to blow the surface of the workpiece can further remove moisture and residues, reduce the impact on subsequent processes, and improve the quality and finish of the final product.

[0014] By adopting the above technical solution, it is possible to achieve accurate steam polishing of acrylic workpieces of different materials, effectively improving the polishing quality and efficiency. The temperature adjustment function enables the steam spray pot to be flexibly adjusted within the range of 100°C to 150°C to meet the needs of various acrylic materials, thereby ensuring the consistency and stability of the polishing effect. At the same time, adding an appropriate amount of wetting agent during the steam polishing process can significantly improve the contact effect between the steam and the workpiece surface, further improve the polishing uniformity, reduce polishing time and energy consumption, and reduce production costs.

[0016] By adopting the above technical solutions, the acrylic material polishing device can effectively improve the polishing quality and efficiency, ensuring that the workpiece surface meets the requirements of transparency and smoothness Ra0.2-Ra0.4. The stable design of the support frame and the application of the infrared preheating module reduce the risk of stress cracks during the polishing process. At the same time, the multi-stage cleaning steps ensure the surface cleanliness, and the temperature adjustment function of the steam polishing equipment enables acrylic workpieces of different materials to obtain ideal polishing effects. In addition, the design of the auxiliary tools facilitates detail processing and improves the overall convenience and flexibility of operation.

[0017] Preferably, the support frame is provided with a fixing point with adjustable height to accommodate workpieces of different thicknesses, and the fixing point has an anti-slip design to ensure the stability of the workpiece; and a suction cup is provided at the bottom of the support frame to increase the overall stability of the device.

[0019] Preferably, it also includes a hook for hanging the workpiece to be polished on the support frame, the hook is made of high temperature resistant material to prevent deformation during steam polishing; and a spring buffer device is provided on the hook to reduce the vibration of the workpiece during steam polishing.

[0020] By adopting the above technical solution, the design of the hook can effectively fix the workpiece to be polished, ensuring that it will not be displaced due to vibration during the steam polishing process, thereby improving the accuracy and stability of polishing. At the same time, the hook made of high-temperature resistant material can maintain its shape in a high-temperature environment, prevent deformation, and ensure the safety and reliability of the workpiece. The spring buffer device can effectively absorb and reduce the vibration of the workpiece during the steam polishing process, further improving the polishing quality and efficiency.

[0028] Figure 1 This is one of the process flow charts of a polishing process for an acrylic material in an embodiment of the present application.

[0029] Figure 2 This is the second process flow chart of a polishing process for an acrylic material in an embodiment of the present application. DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] Embodiment 1: Reference Figure 1 and Figure 2 , a polishing process for acrylic material provided in an embodiment of the present application comprises the following steps: (a) Rough polishing: The workpiece to be polished should be placed stably, and small workpieces should be fixed to reduce work defects caused by workpiece displacement during the polishing process. Use 1000-grit sandpaper to remove knife marks from the surface of the part in one direction, and polish multiple positions alternately. Specifically, a workbench with a non-slip pad can be used to fix the workpiece to ensure that the workpiece does not move during the polishing process. In addition, 1000-grit sandpaper can be selected as wet sandpaper and kept wet during the polishing process to improve the effect of removing knife marks. After the rough polishing step, use a soft cloth to wipe the surface of the workpiece dry so that the polishing effect can be better observed. For example, wet sandpaper can be made of natural or synthetic fibers to increase friction and durability.

[0032] (b) Preliminary cleaning: Use clean water to clean the rough polished parts to remove dirt and oil on the surface of the parts. In order to reduce the side effects of using alcohol or ultrasonic cleaning equipment, it is recommended to rinse with running water and then wipe dry with a clean soft cloth. During this process, you can use a brush to gently remove the remaining sand particles to ensure thorough cleaning. For example, you can use a nylon brush or a wire brush to gently scrub to ensure that the surface is clean and free of residue.

[0033] (c) Fine polishing: The workpiece to be polished is placed steadily again, and small workpieces also need to be fixed. Use 3000-grit sandpaper or polishing paste to fine-polish the appearance of the part in one direction for 2-5 minutes. For the cavity position, use a polishing pen to clamp a cotton swab or bamboo stick to fine-polish the cavity position for 1-2 minutes, and polish multiple positions alternately. Here, at least one of the 3000-grit sandpaper or polishing paste can be made of a composite material containing fine particles to enhance the polishing effect and smoothness. In addition, during the fine polishing process, a pneumatic polishing pen can be used with a low-speed rotating head to reduce the pressure on the workpiece and reduce damage to the workpiece surface. For example, a pneumatic polishing pen can be selected with an adjustable speed model to adapt to workpieces of different hardness.

[0034] (d) Secondary cleaning: Use clean water to clean the polished parts to remove dirt and oil on the surface of the parts. Similarly, use a brush to gently remove residual sand or abrasives, and use compressed air to blow the surface of the workpiece after each cleaning to further remove moisture and residue. For example, you can use a high-pressure air gun to blow quickly to ensure that the surface is completely dry.

[0035] (e) Steam polishing: Hang the polishing workpiece to ensure that the workpiece does not shake, and reduce the workpiece displacement during the polishing process to cause work defects. Take good care of yourself before the operation, use the headlight repair potion and steam spray pot to polish the surface of the part, through holes, and tooth holes for 1-2 minutes, and repeat this action 2-3 times, polish multiple positions alternately to reduce the impact on the size of the part. The steam spray pot has a temperature adjustment function, and the steam temperature can be adjusted as needed, ranging from 100℃ to 150℃ to adapt to acrylic workpieces of different materials. During the steam polishing process, an appropriate amount of wetting agent can be added to the spray pot to improve the contact effect between the steam and the workpiece surface. For example, the wetting agent can be silicone oil or other lubricants, which help to improve the permeability and smoothness of the steam.

[0036] (f) Final cleaning: Use clean water to clean the steam-polished parts to remove dirt and oil on the surface of the parts. Finally, use a clean soft cloth to wipe the surface of the workpiece dry and check for matte and appearance defects. For example, you can use an absorbent cotton ball to gently wipe to ensure that the surface is smooth and flawless.

[0037] The implementation principle of this embodiment is: Through the above steps, the whole process of acrylic material from rough polishing to fine polishing and then to steam polishing is realized. First, use 1000-grit sandpaper to remove large knife marks, then use 3000-grit sandpaper or polishing paste for fine polishing, and finally use steam polishing to eliminate fine matte and knife marks. The whole process is simple to operate, does not require special training, and has low requirements for the environment and equipment. In particular, the steam polishing step effectively eliminates the matte by slightly melting the surface of the workpiece and re-cooling it, while having little effect on the size of the part and making the product quality more stable.

[0038] Embodiment 2: The difference between this embodiment and the above-mentioned embodiment is that an infrared preheating module is added to preheat the workpiece before steam polishing to reduce stress cracks during the polishing process.

[0039] (g) Infrared preheating: Before the steam polishing step, the workpiece to be polished is preheated using an infrared preheating device, with the preheating temperature set at 60°C to 80°C for about 5 minutes. During the preheating process, the surface of the workpiece is evenly heated, which helps reduce the risk of stress cracks during the polishing process. The infrared preheating device can be selected with a multi-stage temperature control function to accurately control the preheating temperature. For example, a multi-stage temperature control device can set multiple temperature intervals to gradually increase the workpiece temperature to reduce problems caused by sudden temperature changes.

[0040] The implementation principle of this embodiment is: By adding an infrared preheating step, the stress cracking problem caused by sudden temperature changes is effectively reduced. Preheating gradually increases the surface temperature of the workpiece, thereby reducing the stress concentration phenomenon when it is suddenly heated. This not only improves the polishing quality and stability, but also extends the service life of the workpiece. This measure is particularly important when processing parts with complex shapes and special structures.

[0041] Embodiment 3: The difference between this embodiment and the above embodiment is that a device for polishing acrylic material is introduced, comprising: (i) a support frame for fixing the workpiece to be polished; (ii) Abrasive tools, including 1000 grit sandpaper and 3000 grit sandpaper or polishing paste; (iii) cleaning equipment, including water containers, without alcohol or ultrasonic cleaning equipment; (iv) steam polishing equipment, including steam sprayers and repair potions; (v) Auxiliary tools, including bamboo sticks or wooden sticks for detail processing; scouring pads for cleaning surfaces; pneumatic polishing pens for fine polishing of cavity positions; and infrared preheating modules for preheating the workpiece before steam polishing to reduce stress cracks during the polishing process.

[0042] Furthermore, each of the above structures is further explained.

[0043] Support frame: The support frame is provided with height-adjustable fixing points to accommodate workpieces of different thicknesses, and the fixing points have a non-slip design to ensure the stability of the workpiece. A suction cup is provided at the bottom of the support frame to increase the overall stability of the device. Specifically, the support frame can adopt a metal frame structure, and the fixing points can be adjusted by bolts or buckles to accommodate workpieces of various thicknesses. For example, the metal frame can be made of aluminum alloy or stainless steel to improve strength and corrosion resistance.

[0044] Grinding tools: It includes 1000-grit sandpaper and 3000-grit sandpaper or polishing paste. 1000-grit sandpaper is mainly used for rough polishing to remove larger knife marks; 3000-grit sandpaper or polishing paste is used for fine polishing to remove fine scratches. In addition, it is equipped with a pneumatic grinding pen for fine polishing of the cavity position. The pneumatic grinding pen can be designed with a low-speed rotating head to reduce the pressure on the workpiece. For example, 3000-grit sandpaper can be selected with ceramic-based sandpaper to improve wear resistance and cutting ability.

[0045] Cleaning equipment: Includes a clean water container, no alcohol or ultrasonic cleaning equipment. The clean water container can be a simple plastic bucket or stainless steel basin to store the cleaning water. During the cleaning process, it can be rinsed with running water and then wiped dry with a clean soft cloth. During this process, a brush can be used to gently remove residual sand particles to ensure thorough cleaning. For example, the clean water container can be selected with a moderate capacity to facilitate replacement and cleaning.

[0046] Steam polishing equipment: Includes a steam spray pot and repair potion. The steam spray pot has a temperature regulation function, and the steam temperature can be adjusted as needed, ranging from 100℃ to 150℃ to adapt to acrylic workpieces of different materials. During the steam polishing process, an appropriate amount of wetting agent can be added to the spray pot to improve the contact effect between the steam and the workpiece surface. The steam spray pot is also equipped with a filter to filter impurities and prevent nozzle clogging, and is set with an automatic cleaning mode to clean the filter regularly to extend its service life. For example, the filter can use a high-efficiency HEPA filter to ensure long-term reliability.

[0047] Auxiliary tools: It includes bamboo sticks or wooden sticks for detail processing; scouring pads for cleaning surfaces; and pneumatic polishing pens for fine polishing of cavity positions. In addition, it also includes an infrared preheating module for preheating the workpiece before steam polishing to reduce stress cracks during polishing. For example, the scouring pad can be designed with two sides, one soft and the other rough, to meet the cleaning needs of different parts.

[0048] The implementation principle of this embodiment is: The integrated device design improves the efficiency and precision of polishing work. The adjustable height design and non-slip fixing points of the support frame ensure the stability of the workpiece, which is particularly suitable for processing workpieces of different thicknesses and shapes. There are various choices of grinding tools, which can be flexibly selected according to actual needs. The cleaning equipment and steam polishing equipment are fully functional and can meet the cleaning and polishing requirements at all stages. The equipment of auxiliary tools further enhances the ability to handle details and ensures the high quality standards of the final product.

[0049] Embodiment 4: The difference between this embodiment and the above embodiment is that a measuring instrument is added to evaluate the quality of the polished parts.

[0050] Specifically, it includes optical microscopes and roughness meters, which are used to accurately detect the flatness and finish of the surface of parts. Optical microscopes can help observe microstructures and identify subtle scratches or defects; roughness meters can quantify surface roughness to ensure that the Ra0.2-Ra0.4 standard is met. The measuring instrument is connected to a data recording module, which can record the test results in real time for quality traceability. For example, optical microscopes can choose high-resolution models to obtain clearer images; roughness meters can choose portable models for on-site use.

[0051] The implementation principle of this embodiment is: By introducing measuring instruments, not only can the polishing effect be evaluated intuitively, but potential problems can also be discovered in time. The high magnification of the optical microscope allows the operator to clearly see every detail of the workpiece surface, while the digital reading of the roughness meter provides objective data support. The use of the data recording module enables the results of each test to be saved, which is convenient for subsequent quality management and improvement. This scientific methodology greatly improves the reliability and consistency of production.

[0052] Embodiment 5: The difference between this embodiment and the above-mentioned embodiment is that the safety and durability of the steam polishing equipment are enhanced.

[0053] Specifically, the steam spray pot in the steam polishing equipment is equipped with a filter to filter impurities and prevent the nozzle from being blocked. It is also equipped with an automatic cleaning mode to clean the filter regularly to extend the service life. In addition, the steam spray pot is also equipped with a flow control valve, which can adjust the steam flow according to actual needs to optimize the polishing effect. In order to further improve safety, the handle of the spray pot is made of heat-insulating material to prevent the operator from being scalded. The hook is made of high-temperature resistant material to prevent deformation during steam polishing; and a spring buffer device is provided on the hook to reduce the vibration of the workpiece during steam polishing. For example, the heat-insulating material can be made of polyamide or silicone to provide good heat-insulating performance; the hook can be made of stainless steel to resist high-temperature deformation.

[0054] The implementation principle of this embodiment is: Through a series of design improvements, the safety and durability of steam polishing equipment have been significantly improved. The settings of filters and automatic cleaning modes effectively prevent nozzle clogging and extend the service life of the equipment. The addition of a flow control valve allows the operator to adjust the steam flow according to actual conditions and optimize the polishing effect. The heat insulation design of the handle part and the spring buffer device on the hook greatly improve the comfort and safety of the operator. These improvements not only improve work efficiency, but also provide protection for the health and safety of the operator.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
