Description

Technical Field

[0001] This invention relates to the field of metal surface processing technology, specifically to an aluminum alloy template surface treatment device and method. Background Technology

[0002] Aluminum alloy formwork is a temporary support structure system used in building construction for concrete pouring and forming. Various specifications of formwork and supporting reinforcement accessories are produced through processes such as material cutting, punching, and welding. After precise assembly according to drawings, it is used in the concrete construction of the project. Surface treatment of the inner wall of the aluminum alloy formwork at the contact surface with the concrete improves the smoothness of the formed concrete and facilitates demolding, thereby improving construction efficiency and results.

[0003] Because aluminum alloy formwork is designed according to architectural drawings, its dimensions vary. Surface treatment of aluminum alloy formwork typically employs manual coating or simple mechanical methods, which suffer from low efficiency, uneven coating, and difficulty in adapting to large-scale production. Some factories have introduced automated mechanical systems, using conveyor belts and coating mechanisms for automatic processing; however, these systems often lack flexibility and cannot adapt to diverse product requirements, especially when processing formwork with significant size variations in batches, making it difficult to ensure coating consistency. Furthermore, existing heating methods, typically using external electric heating or traditional ovens, cannot ensure uniform heating of the entire formwork surface, affecting the surface treatment effect.

[0004] Therefore, it is necessary to provide an aluminum alloy template surface treatment device and method to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy template surface treatment device, including a bracket, a support beam is mounted in the bracket, multiple vertical guide rails are distributed in the support beam, sliders are symmetrically arranged on both sides of each vertical guide rail, the sliders on both sides are connected together by a horizontal bar, and a vertical clamping rod is fixed on each slider.

[0006] A connecting shaft parallel to the support beam is provided above it. One end of the connecting shaft is connected to a bracket on one side, and multiple spraying components are distributed in the connecting shaft.

[0007] The bottom of the bracket is equipped with a row of heating tiles;

[0008] The support beam is rotatably connected to the bracket, and one end of the bracket is connected to the support beam via a servo-rotatable turntable.

[0009] Furthermore, as a preferred embodiment, each end of the support beam is provided with a centrally servo-driven rotating rod, and each end of the rotating rod is rotatably connected to a corresponding crossbar via a separate rod.

[0010] Furthermore, as a preferred embodiment, one end of the connecting shaft is connected to a bracket on one side via a drive platform, the drive platform being capable of driving the connecting shaft to move back and forth and up and down.

[0011] Furthermore, as a preferred embodiment, the bracket is also provided with a driven connecting platform sleeved in the connecting shaft. The driven connecting platform moves up and down with the driving platform and is slidably connected to the connecting shaft.

[0012] Furthermore, as a preferred embodiment, the clamping rod is provided with a plurality of retractable clamping blocks arranged vertically on one side near the support beam, and the clamping blocks are connected to the clamping rod by springs, and the elastic force of the springs causes the clamping blocks to extend out of the clamping rod.

[0013] Furthermore, preferably, a plurality of rollers are rotatably provided above the support beam.

[0014] Furthermore, preferably, each of the clamps is provided with a position sensor;

[0015] Each of the rollers is equipped with a position sensor.

[0016] Furthermore, as a preferred embodiment, the spraying assembly includes a retaining sleeve fixed to the connecting shaft, and multiple telescopic spray bars are distributed below the retaining sleeve.

[0017] Furthermore, as a preferred embodiment, one end of the fixed sleeve is fixed with a threaded sleeve, the outer wall of the threaded sleeve is threadedly connected to a first rotating sleeve, the outer wall of the first rotating sleeve is threadedly connected to a second rotating sleeve, the outer wall of the second rotating sleeve is rotatably connected to a connecting ring, and multiple connecting rods are hinged in the connecting ring, the other end of the connecting rods being respectively hinged to each telescopic spray bar.

[0018] The first rotating sleeve is fixed with a first push rod, and the second rotating sleeve is fixed with a second push rod. The first push rod and the second push rod are symmetrically distributed.

[0019] A push plate is fixed to the top of the clamping block, and the first push rod and the second push rod are attached to the corresponding push plate.

[0020] A method of using an aluminum alloy template surface treatment device includes:

[0021] S1. Place the aluminum alloy template to be processed on the support beam, ensuring smooth contact between the template and the rollers. Activate the heating tile to heat the coating on the template through the heating tile at the bottom of the support.

[0022] S2. Drive the rotating rod to rotate, and the two horizontal bars move closer to each other until the clamping rod clamps and centers the template. The corresponding clamping block supports the template to prevent it from moving. Control the drive platform to adjust the connecting shaft to the axis position of the template. At the same time, the push plate pushes the first push rod and the second push rod to rotate, so that the first rotating sleeve and the second rotating sleeve move away from the fixed sleeve. This causes the connecting rod to push the telescopic spray bar to shorten, so that the telescopic spray bar is kept at a suitable distance from the template to ensure that the inner wall of the template can be sprayed evenly.

[0023] S3. The connecting shaft is moved back and forth by the drive platform, so that the spraying component can evenly spray a layer of silane coupling agent onto the inner wall of the template.

[0024] S4. By rotating the turntable, the support beam and template rotate downwards to align with the heating tile. The natural convection of the rising hot airflow ensures uniform heating of the coating. The silane coupling agent can react with the hydroxyl groups on the inner wall of the aluminum alloy template to form chemical bonds, making the inner wall of the template hydrophobic.

[0025] S5. By rotating the turntable, the support beam and template rotate upwards, and S and S are repeated multiple times to ensure that the coating is evenly sprayed on the inner wall of the template and that the coating reacts fully with the aluminum alloy.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] In this invention, the device integrates several key components, including a spraying assembly, heating tiles, and clamping rods, to achieve surface treatment of the inner wall of the aluminum alloy template, including the spraying and heating reaction of a hydrophobic coating. This ensures that the template does not easily stick to the concrete, and the template does not need to be moved after the coating is applied. Multiple spraying and heating processes can be repeated, ensuring more uniform heating of the coating and preventing the coating from curing and reducing the efficiency of the heating reaction. The heating tiles at the bottom of the device utilize the natural convection principle of rising hot airflow, effectively transferring heat to the entire area and improving the thermal energy utilization rate of the heating tiles.

[0028] In this invention, through the coordinated action of components such as the support beam, rotating rod, and clamping rod, the device can adapt to the processing requirements of aluminum alloy templates of different sizes, ensuring that the coating is evenly sprayed on the inner side of the template. The reciprocating movement of the connecting shaft enables the spraying assembly to spray evenly along the axial direction of the template, ensuring uniform axial distribution of the coating, while the up-and-down movement changes the distance between the connecting shaft and the template, avoiding obstruction of the rotation of the support beam. When the two crossbars approach each other and clamp the template, the telescopic spray bar shortens synchronously, maintaining a suitable distance between the telescopic spray bar and the template, ensuring even spraying of the inner wall of the template.

[0029] This invention is equipped with multiple position sensors, including sensors on the clamping blocks and rollers, which can identify the height and length of the template in real time, thereby achieving intelligent control and adjustment. Attached Figure Description

[0035] Please see Figure 1 and Figure 2 In this embodiment of the invention, an aluminum alloy template surface treatment device includes a bracket 1, in which a support beam 2 is mounted, and multiple vertical guide rails 2 are distributed in the support beam 2. Each vertical guide rail 2 has a slider 5 symmetrically arranged on both sides, and the sliders 5 on both sides are connected together by a horizontal bar 4. Each slider 5 is fixed with a vertical clamping rod 6.

[0036] A connecting shaft 8 parallel to the support beam 2 is provided above it. One end of the connecting shaft 8 is connected to a bracket 1 on one side. Multiple spraying components 7 are distributed in the connecting shaft 8.

[0037] In this embodiment, each end of the support beam 2 is equipped with a centrally servo-driven rotating rod 23. Each end of the rotating rod 23 is rotatably connected to a corresponding crossbar 4 via a separate rod. When the two rotating rods 23 rotate symmetrically, they can push the two crossbars 4 closer together, causing the clamping rod 6 to clamp and center the template. This allows the spraying assembly 7 to spray hydrophobic coating onto the inside of the template, thus adapting to the processing requirements of aluminum alloy templates of different sizes and ensuring that the coating is evenly sprayed onto the inside of the template.

[0038] In this embodiment, a row of heating tiles 11 is provided at the bottom of the support 1. The heating tiles 11 can heat the coating to cause a heating reaction in the coating.

[0039] In this embodiment, the support beam 2 is rotatably connected to the bracket 1, and one end of the bracket 1 is connected to the support beam 2 via a servo-rotatable turntable 21. The rotation of the turntable 21 allows the support beam 2 and the template connected to it to rotate downwards and align with the heating tile 11. As the hot air rises, heat can be effectively transferred to the upper part, forming natural convection, thereby heating the entire area more comprehensively and improving the thermal energy utilization rate of the heating tile 11.

[0040] Furthermore, since the template does not need to be transferred after the paint is applied, the spraying and heating process can be repeated multiple times, which can make the paint heating more uniform and avoid the problem of heat not being able to be transferred to the interior of the paint after thick paint is applied. It can also avoid the problem of the paint solidifying after the template is sprayed, which would reduce the heating reaction efficiency.

[0041] In this embodiment, one end of the connecting shaft 8 is connected to a bracket 1 on one side via a drive platform 9. The drive platform 9 can drive the connecting shaft 8 to move back and forth and up and down. The reciprocating movement of the connecting shaft 8 enables the spraying assembly 7 to spray evenly along the axial direction of the template, ensuring uniform axial distribution of the paint. The up and down movement of the connecting shaft 8 can change the distance between the connecting shaft 8 and the template, preventing the connecting shaft 8 and the spraying assembly 7 from obstructing the rotation of the support beam 2, and also ensuring that the connecting shaft 8 is located at the center of the template.

[0042] In this embodiment, the bracket 1 is further provided with a driven connecting platform 10 sleeved in the connecting shaft 8. The driven connecting platform 10 rises and falls with the drive platform 9, and the driven connecting platform 10 is slidably connected to the connecting shaft 8. The driven connecting platform 10 makes the connecting shaft 8 a cantilever beam structure, thereby improving the stability of the connecting shaft 8.

[0043] Please see Figure 3 In this embodiment, multiple retractable clamping blocks 61 are arranged vertically on the side of the clamping rod 6 near the support beam 2. A spring connects each clamping block 61 to the clamping rod 6, and the spring force causes the clamping block 61 to extend beyond the clamping rod 6. When the clamping rod 6 is pressed against the outer wall of the template, the clamping block 61 corresponding to the template's location is squeezed into the clamping rod 6. The remaining clamping blocks 61 can clamp the template. Furthermore, when the support beam 2 rotates, causing the template to flip downwards, the protruding clamping blocks 61 can support the template and prevent it from falling.

[0044] In this embodiment, multiple rollers 22 are rotatably provided above the support beam 2. The rollers 22 are slightly higher than the height of the vertical guide rail 3, allowing the template to slide smoothly on the support beam 2 for easy loading and unloading.

[0045] In this embodiment, each clamping block 61 is equipped with a position sensor. The position sensor can be a pressure sensor or an electrical signal on / off sensor, thereby identifying the height of the template to control the drive platform 9 to adjust the connecting shaft 8 to the axial center position of the template.

[0046] In this embodiment, each roller 22 is equipped with a position sensor. The position sensor can be a pressure sensor or an electrical signal on / off sensor, thereby identifying the length of the template to control the spraying position of the spraying assembly 7.

[0047] Please see Figure 3 In this embodiment, the spraying assembly 7 includes a fixing sleeve 71, which is fixed to the connecting shaft 8. Multiple telescopic spray rods 72 are distributed below the fixing sleeve 71. The telescopic spray rods 72 are connected to a spraying pump to spray paint onto the inner wall of the template.

[0048] In this embodiment, a threaded sleeve 73 is fixed to one end of the fixed sleeve 71, a first rotating sleeve 74 is threadedly connected to the outer wall of the threaded sleeve 73, a second rotating sleeve 75 is threadedly connected to the outer wall of the first rotating sleeve 74, a connecting ring 76 is rotatably connected to the outer wall of the second rotating sleeve 75, and multiple connecting rods 77 are hinged in the connecting ring 76, and the other end of the connecting rods 77 is respectively hinged to each telescopic spray bar 72;

[0049] The first rotating sleeve 74 is fixed with a first push rod 78, and the second rotating sleeve 75 is fixed with a second push rod 79. The first push rod 78 and the second push rod 79 are symmetrically distributed.

[0050] The top of the clamping block 61 is fixed with a push plate 12, and the first push rod 78 and the second push rod 79 are attached to the corresponding push plate 12.

[0051] In other words, when the two crossbars 4 approach each other and clamp the template, the push plate 12 pushes the first push rod 78 and the second push rod 79 to rotate, causing the first rotating sleeve 74 and the second rotating sleeve 75 to move away from the fixed sleeve 71, thereby causing the connecting rod 77 to push the telescopic spray bar 72 to shorten, so that the telescopic spray bar 72 is kept at a suitable distance from the template, ensuring that the inner wall of the template can be sprayed evenly.

[0052] A surface treatment for aluminum alloy templates to prevent hair loss, comprising:

[0053] S1. Place the aluminum alloy template to be processed on the support beam 2, ensuring smooth contact between the template and the roller 22. Start the heating tile 11 to heat the coating on the template through the heating tile 11 at the bottom of the bracket 1.

[0054] S2. Drive the rotating rod 23 to rotate, and the two horizontal bars 4 move closer to each other until the clamping rod 6 clamps and centers the template. The corresponding clamping block 61 supports the template and prevents the template from moving. Control the driving platform 9 to adjust the connecting shaft 8 to the axis position of the template. At the same time, the push plate 12 pushes the first push rod 78 and the second push rod 79 to rotate, so that the first rotating sleeve 74 and the second rotating sleeve 75 move away from the fixed sleeve 71. This causes the connecting rod 77 to push the telescopic spray rod 72 to shorten, so that the telescopic spray rod 72 is kept at a suitable distance from the template, ensuring that the inner wall of the template can be sprayed evenly.

[0055] S3. The connecting shaft 8 is moved back and forth by the drive platform 9, so that the spraying component 7 can evenly spray a layer of silane coupling agent onto the inner wall of the template.

[0056] S4. By rotating the turntable 21, the support beam 2 and the template rotate downwards to align with the heating tile 11. The natural convection of the rising hot airflow makes the coating heat evenly. The silane coupling agent can react with the hydroxyl groups on the inner wall of the aluminum alloy template to form chemical bonds, making the inner wall of the template hydrophobic.

[0057] S5. By rotating the turntable 21, the support beam 2 and the template rotate upwards, and S3 and S4 are repeated multiple times to ensure that the coating is evenly sprayed on the inner wall of the template and that the coating reacts fully with the aluminum alloy.

[0058] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
