Description
Technical Field
[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a sandblasting device for high wear resistance aluminum profiles. Background Technology
[0002] Aluminum profile sandblasting machines are indispensable key equipment in modern industrial production, especially in the field of metal surface treatment, where they hold a pivotal position. Their core technology utilizes compressed air as a power source to drive various abrasive media, such as diamond abrasive, glass beads, or steel shot, to form a high-speed jet. This abrasive physically impacts the surface of the aluminum profile, efficiently removing oxide layers, burrs, oil stains, and other impurities. Through precise control of abrasive particle size and blasting time, sandblasting technology can achieve customized surface roughness treatment of aluminum profiles, meeting the specialized surface performance requirements of high-end applications such as lightweight automotive components and building curtain wall profiles.
[0003] However, traditional manual sandblasting of aluminum profiles, relying heavily on manual operation, suffers from numerous insurmountable drawbacks. Operators must wear heavy protective clothing and breathing masks, and be inside a sealed sandblasting chamber, holding the spray gun in one hand and holding the aluminum profile to be treated in the other, performing single-sided sandblasting. The limitations of this purely manual operation mode are obvious. Maintaining stable and precise control of the spray gun angle and spray distance is difficult, especially when dealing with complex structural areas such as grooves and edges of the aluminum profile, easily leading to blind spots in sandblasting coverage and uneven sandblasting results. Furthermore, the response speed of manually adjusting the spray pressure is relatively slow, often resulting in over- or under-blasting during the sandblasting process, affecting not only the consistency of the aluminum profile surface treatment quality but also directly hindering the improvement of overall production efficiency.
[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-wear-resistant aluminum profile sandblasting device.

[0009] Preferably, the high wear-resistant aluminum profile sandblasting device of this utility model has two clamping plates arranged opposite each other. The two clamping plates are located on the left and right sides below the nozzle, and are respectively connected to two electric push rods. The electric push rods drive the plates to move in opposite directions or away from each other to clamp or release the aluminum profile.
[0010] More preferably, in the high wear-resistant aluminum profile sandblasting device of this utility model, a rubber pad is provided on the inner side of the clamping plate. The rubber pad is used to increase the friction between the clamping plate and the aluminum profile to prevent the aluminum profile from sliding during the sandblasting process.

[0012] In other embodiments, the high wear-resistant aluminum profile sandblasting device of the present invention further includes: a control panel, which is disposed on the outside of the sandblasting box, for controlling the working status of the air compressor, the rotary motor and the servo motor.
[0013] As an additional embodiment, the high wear-resistant aluminum profile sandblasting device of this utility model further includes: a support leg, which is disposed at the bottom of the sandblasting box and is used to support the sandblasting box.
[0014] As another additional embodiment, the high wear-resistant aluminum profile sandblasting device of this utility model further includes: two mounting brackets, which are set inside the sandblasting box to support two electric push rods, so that the electric push rods can stably drive the clamping plate to move.
[0015] Furthermore, the high wear-resistant aluminum profile sandblasting device of this utility model has a sealed box structure for sandblasting to prevent the leakage of sandblasting abrasive and dust.
[0016] Compared with existing technologies, this invention has the following advantages: The device innovatively incorporates a rotary motor and a servo motor driven mechanism, enabling the aluminum profile to rotate and the nozzle to reciprocate left and right during sandblasting. This allows the nozzle to perform multi-angle, all-around sandblasting on the aluminum profile.

Simultaneously, the precise control characteristics of the servo motor effectively avoid over- or under-blasting caused by the lag in pressure adjustment in traditional manual sandblasting, ensuring the accuracy of sandblasting pressure and spraying time, thereby significantly improving the quality and consistency of aluminum profile surface treatment. In summary, this high-wear-resistant aluminum profile sandblasting device fundamentally solves the technical problems of low efficiency and unstable quality in existing manual sandblasting, significantly improving sandblasting efficiency and quality, and meeting the high-efficiency, high-quality requirements of industrial production for aluminum profile surface treatment.

Detailed Implementation
[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0023] With the rapid development of modern industrial technology, aluminum profiles, due to their excellent lightweight and corrosion resistance, are increasingly widely used in key fields such as aerospace, automobile manufacturing, and architectural decoration. To meet the stringent requirements of various industries for the surface quality and performance of aluminum profiles, sandblasting technology, as an efficient and economical surface treatment method, has received increasing attention. In the precision processing of aluminum profiles, such as the manufacturing of lightweight automotive components and high-end building curtain wall profiles, sandblasting is often required to remove defects such as oxide layers and burrs, and to obtain a specific surface roughness, thereby improving the product's wear resistance, adhesion, and appearance quality. However, in existing technologies, the limitations of manual sandblasting methods are becoming increasingly apparent, especially when dealing with aluminum profile workpieces with complex structures and high surface requirements. For example, when sandblasting aluminum profiles for automotive radiators, these profiles typically have complex fin structures and curved pipes. Using traditional manual sandblasting methods, operators struggle to precisely control the angle and distance of the spray gun, easily resulting in uneven sandblasting, especially at the fin roots and curved areas, where blind spots are easily created. This leads to inconsistent surface treatment quality, severely impacting the radiator's heat dissipation efficiency and lifespan. To address these issues, this application proposes a high-wear-resistant aluminum profile sandblasting device, aiming to overcome the limitations of manual sandblasting and achieve efficient and high-quality sandblasting treatment of aluminum profiles.
[0024] To better understand the technical solution of this application, the key terms involved in this application are first explained. The blasting box 1 serves as the main frame of the entire device, constructing a sealed space for blasting operations to effectively prevent the leakage of abrasive and dust, ensuring a clean and safe working environment. The abrasive storage tank 2 stores the abrasives required for blasting, such as diamond, glass beads, or steel shot. Different types and particle sizes of abrasives can be selected according to different blasting requirements. The air compressor 3 serves as the power source for blasting, providing compressed air for the high-speed jet of the abrasive. The conveying pipe 4 is responsible for conveying the abrasive from the abrasive storage tank 2 to the nozzle 5 inside the blasting box 1. The nozzle 5 is a key component for abrasive jetting; its structural design directly affects the shape, speed, and uniformity of the jet. The rotary motor 12 and the servo motor 15 are the core driving components for achieving multi-angle blasting in this application. They work together to drive the aluminum profile to rotate and the nozzle 5 to move, respectively, thereby achieving all-around coverage blasting of the aluminum profile surface. The clamping plate 13 and the electric push rod 11 constitute the clamping and fixing mechanism for the aluminum profile, ensuring that the aluminum profile remains stable during the sandblasting process.
[0025] like Figures 1 to 4 The high wear-resistant aluminum profile sandblasting device shown includes a sandblasting box 1, and also includes:
[0026] Abrasive storage tank 2 is located outside the blasting box 1 and is used to store blasting abrasive.
[0027] Air compressor 3, located on top of abrasive storage tank 2, is used to provide power for sandblasting;
[0028] The conveying pipe 4 connects the air compressor 3 and the sandblasting box 1. The air compressor 3 is used to convey the sandblasting abrasive in the abrasive storage tank 2 to the sandblasting box 1.
[0029] Nozzle 5 is slidably disposed inside the sandblasting box 1 and connected to the conveying pipe 4 for spraying abrasive;
[0030] A rotary motor 12 is installed inside the sandblasting box 1 to drive the aluminum profile to rotate;
[0031] Clamping plate 13 is located inside the sandblasting box 1 and below the nozzle 5, and is used to clamp and fix the aluminum profile.
[0032] Electric push rod 11, connected to clamping plate 13, is used to drive clamping plate 13 to clamp or loosen aluminum profile;
[0033] Servo motor 15 is located inside the sandblasting box 1;
[0034] The lead screw 16 is connected to the servo motor 15 and is driven to rotate by the servo motor 15.
[0035] The ball nut 17 is threadedly connected to the lead screw 16 and fixedly connected to the nozzle 5. It is used to drive the nozzle 5 to move left and right to achieve multi-angle sandblasting.
[0036] In practice, the aluminum profile to be sandblasted is clamped using clamping plate 13. Air compressor 3 is started, generating compressed air. This compressed air drives the abrasive in abrasive storage tank 2, which is then transported to nozzle 5 via delivery pipe 4. Simultaneously, rotary motor 12 is started, causing the clamping mechanism and aluminum profile to rotate. Servo motor 15 also starts synchronously, driving lead screw 16 and ball nut 17 to move nozzle 5 horizontally left and right, performing reciprocating scanning spraying. The sprayed abrasive impacts the aluminum profile surface at high speed, peeling off the oxide layer and impurities, thus achieving the purpose of sandblasting.
[0037] As one embodiment of this utility model, it also includes:
[0038] A protective door 7, located at the front of the sandblasting box 1, is used to seal the opening of the sandblasting box 1. The protective door 7 is installed at the front opening of the sandblasting box 1, and its main function is to completely seal the opening of the sandblasting box 1 during sandblasting operations, forming a more enclosed sandblasting space. This effectively prevents abrasive dust and flying abrasive particles generated during the sandblasting process from escaping from the sandblasting box 1, thereby minimizing dust pollution in the workplace, protecting the health of operators, and maintaining a clean working environment.
[0039] As one embodiment of this utility model, it also includes:
[0040] The viewing window 6 is located on the front side of the sandblasting box 1 and above the protective door 7, for observing the sandblasting situation inside the sandblasting box 1. During the sandblasting process, the operator can monitor the working status inside the sandblasting box 1 in real time through the viewing window 6, such as the spraying status of the nozzle 5, the rotation of the aluminum profile, and the spraying coverage effect of the abrasive. In short, the addition of the viewing window 6 may seem simple in structure, but it plays a key role in improving the ease of operation and safety of the sandblasting device.
[0041] In one embodiment of this utility model, two clamping plates 13 are arranged opposite each other, located on the left and right sides below the nozzle 5, and connected to two electric push rods 11 respectively. The electric push rods 11 drive the plates to move in opposite directions or back to back to clamp or release the aluminum profile. Specifically, the two clamping plates 13 can be designed symmetrically to ensure a uniform distribution of clamping force on the aluminum profile. The clamping plates 13 can be made of high-strength alloy steel or aluminum alloy to ensure sufficient clamping strength and durability. The electric push rods 11 can be DC electric push rods or cylinder-type push rods, selected according to the actual clamping force and response speed requirements. Using electric push rods 11 as driving elements allows for precise control of the position of the clamping plates 13, thereby precisely adjusting the clamping force to meet the clamping needs of aluminum profiles of different specifications and materials. In summary, the structural design of double clamping plates 13 and double electric push rods 11 makes the clamping of aluminum profiles more stable and reliable, and the clamping force distribution more uniform, avoiding the problems of aluminum profile skewing or displacement that may occur when clamping with a single clamping plate.
[0042] As one embodiment of this utility model, a rubber pad 14 is provided on the inner side of the clamping plate 13. The rubber pad 14 is used to increase the friction between the clamping plate 13 and the aluminum profile to prevent the aluminum profile from sliding during the sandblasting process. The rubber pad 14 is provided on the surface of the clamping plate 13 in contact with the aluminum profile. Its main function is to increase the friction between the clamping plate 13 and the aluminum profile by utilizing the high coefficient of friction of the rubber material itself, thereby effectively preventing the aluminum profile from sliding or shifting during the sandblasting process.
[0043] As one embodiment of this utility model, it also includes:
[0044] The inclined chute 18 is located at the bottom of the sandblasting box 1 and below the nozzle 5, and is used to collect the waste material after sandblasting.
[0045] A collection box 19, located at the end of the inclined chute 18, is used to collect the waste material introduced by the inclined chute 18. The inclined chute 18 is cleverly positioned at the bottom of the sandblasting box 1, and its position is exactly below the nozzle 5. In this way, during the sandblasting operation, the abrasive sprayed onto the surface of the aluminum profile and the waste material peeled off from the surface of the aluminum profile fall naturally onto the inclined surface of the inclined chute 18 under the action of gravity. The inclined surface of the inclined chute 18 guides these waste materials, causing them to slide along the inclined direction of the inclined chute 18, and finally collect at the end of the inclined chute 18 and be introduced into the collection box 19 located at the end of the inclined chute 18.
[0046] In practice, the inclined chute 18 can be manufactured using sheet metal bending or injection molding processes. Its material can be steel plate, stainless steel, or wear-resistant plastic, with the appropriate material selected based on the type and wear level of the abrasive used in the blasting. The inclination angle of the inclined chute 18 can be adjusted according to the flowability of the waste and the installation position of the recycling bin 19. Typically, an inclination angle of 15-30 degrees is sufficient to ensure smooth waste flow. The recycling bin 19 is used to collect the waste introduced from the inclined chute 18. Its shape and size can be designed according to the overall structure of the blasting device and the amount of waste generated. For example, a square or round box structure can be used, with casters at the bottom for easy movement and cleaning. The material of the recycling bin 19 can be the same as the inclined chute 18, or a higher-strength steel can be used to meet the durability requirements for long-term use. To facilitate waste dumping and recycling, the recycling bin 19 can be designed as a detachable structure, or a discharge port can be provided on the side of the bin for easy emptying of the collected waste.
[0047] As one embodiment of this utility model, it also includes:
[0048] The control panel 8 is located on the outside of the sandblasting box 1 and is used to control the working status of the air compressor 3, the rotary motor 12 and the servo motor 15.
[0049] The control panel 8 is installed on the outside of the sandblasting box 1 in an easily accessible position. Its core function is to integrate and control the key power components of the sandblasting device, including the air compressor 3, the rotary motor 12, and the servo motor 15. Thus, operators can centrally and conveniently set parameters, control start and stop, and monitor the status of the entire sandblasting process through the control panel 8, achieving intelligent and user-friendly sandblasting operation.
[0050] As one embodiment of this utility model, it also includes:
[0051] Support leg 9 is located at the bottom of sandblasting box 1 and is used to support sandblasting box 1.
[0052] The addition of support leg 9 provides reliable ground support for the sandblasting device, ensuring the stability of the overall structure of the device.
[0053] As one embodiment of this utility model, it also includes:
[0054] Two mounting brackets 10 are located inside the sandblasting box 1 to support two electric push rods 11, enabling the electric push rods 11 to stably drive the clamping plate 13 to move.
[0055] To ensure stable support for each electric actuator 11 during operation, this application provides two mounting brackets 10, each bracket 10 supporting one electric actuator 11. The mounting brackets 10 are fixed inside the sandblasting box 1, providing a stable mounting platform for the electric actuators 11 and preventing them from swaying or shifting during telescopic movements. This ensures that the electric actuators 11 can accurately and stably drive the clamping plate 13 to perform clamping and releasing actions.
[0056] As one embodiment of this utility model, the sandblasting box 1 is a sealed box structure to prevent the sandblasting abrasive and dust from leaking out.
[0057] To maximize the environmental performance of the sandblasting device and the cleanliness of the operating environment, the overall structure of the sandblasting box 1 was limited to a sealed box structure. This sealed box structure is designed to completely enclose the entire sandblasting operation within the sandblasting box 1, forming a sealed space isolated from the external environment. This fundamentally prevents abrasive dust and flying abrasive particles generated during sandblasting from leaking into the external environment, minimizing dust pollution, protecting the health of operators, and maintaining a clean workplace.
[0058] Working principle of this utility model:
[0059] The user first opens the protective door 7 and observes the interior through the viewing window 6. The aluminum profile is placed between the clamping plates 13 on the left and right sides. The electric push rod 11 is activated to push the clamping plates 13 inward. The rubber pads 14 increase the friction and clamp the profile. After closing the protective door 7, the air compressor 3 is activated through the control panel 8. The abrasive material in the abrasive storage tank 2 is transported to the nozzle 5 through the conveying pipe 4. At the same time, the rotary motor 12 drives the aluminum profile to rotate, and the servo motor 15 drives the lead screw 16 to rotate, causing the ball nut 17 to move the nozzle 5 left and right to achieve multi-angle sandblasting. The waste material after sandblasting slides into the bottom recycling box 19 along the inclined groove 18. The support leg 9 ensures the stability of the sandblasting box 1. The mounting bracket 10 supports the electric push rod 11 above. The sandblasting process can be monitored through the viewing window 6. When cleaning is required, the handle of the recycling box 19 is pulled to remove the waste material for recycling.
[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
