Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing, and in particular to a cooling device for aluminum profile processing. Background Technology

[0002] In the production process of aluminum profile products, precision machining such as high-speed sawing, CNC milling, drilling, tapping, and surface grinding are key steps that give the profiles their final dimensions, shape, and function. These processes generate significant localized heat accumulation, causing the temperature of the aluminum profile workpiece to rise, which in turn leads to deformation of the aluminum profile and reduces the product yield.

[0003] In existing technologies, common cooling methods mainly include natural cooling, compressed air purging, and direct spraying of cooling water or water. Natural cooling relies primarily on air convection for heat dissipation, which is extremely inefficient, time-consuming, and severely restricts production efficiency, failing to meet the demands of continuous and automated production. Compressed air purging provides only limited cooling effects, especially for large workpieces or those with significant heat accumulation, and is also noisy and energy-intensive. Direct spraying of coolant or water is highly efficient, but after spraying, a large amount of coolant or water will remain on the surface, in holes, and in grooves of the aluminum profile. Aluminum is prone to oxidation in humid environments, forming uneven oxide films or water stains, which seriously affect the appearance and surface cleanliness of the workpiece. Furthermore, if the residual coolant or water is not removed in time, it may corrode the surface of the aluminum or precision machining features (such as threaded holes). In addition, wet workpieces cannot be immediately subjected to subsequent processes such as precision measurement, spraying, anodizing, bonding, or packaging. Additional drying steps (such as drying and wiping) must be added, which not only increases the number of processes, time, and energy consumption, but also makes it difficult to integrate seamlessly into automated lines. Utility Model Content

[0004] This utility model provides a cooling device for aluminum profile processing to solve the technical problems of low production efficiency and easy residue of coolant or moisture on the surface of aluminum profiles during spray cooling in the prior art.

[0005] To solve the above problems, the present invention provides a cooling device for aluminum profile processing, which adopts the following technical solution: It includes a frame, a conveying roller assembly mounted on the frame for conveying aluminum profiles, an upper cooling water pipe and a lower cooling water pipe respectively mounted above and below the conveying roller assembly, and multiple water spray nozzles directed towards the aluminum profiles installed on both the upper and lower cooling water pipes; at the discharge end in the conveying direction, an upper drying air pipe and a lower drying air pipe are also mounted above and below the conveying roller assembly, and multiple air spray nozzles directed towards the aluminum profiles are installed on both the upper and lower drying air pipes; a support plate is mounted on the frame, and the lower cooling water pipe and the lower drying air pipe are fixed to the support plate, which has several drainage holes.

[0006] Furthermore, the surface of the conveyor roller assembly is provided with grooves along the axial direction. The depth of the grooves gradually increases from both ends of the roller body towards the center, and the diameter of the roller body gradually decreases from both ends of the roller body towards the center, forming a smoothly transitioning concave structure.

[0007] Furthermore, the surface of the conveyor roller assembly is covered with an anti-slip rubber layer.

[0008] Furthermore, a water collection tank is installed below the support plate, and the water collection tank is connected to the upper cooling water pipe and the lower cooling water pipe through a water pump to form a water circulation system.

[0009] Furthermore, a filter screen is installed inside the water collection tank, and the filter screen is located at the front end of the water pump inlet.

[0010] Furthermore, a water guide plate is installed on the frame, located between the water collection tank and the support plate. The water guide plate is arranged at an angle, with its lower end facing the water collection tank.

[0011] Furthermore, the surfaces of the water guide plate and the support plate are coated with an anti-corrosion coating.

[0012] Furthermore, symmetrical limit guides are provided on both sides of the support plate, and a slide groove matching the limit guide is provided on the frame. The limit guide is set as a wedge structure with a trapezoidal cross section. The support plate can be detachably installed on the frame through the wedge-shaped cooperation between the limit guide and the slide groove.

[0013] Furthermore, the upper cooling water pipe and the upper drying air pipe are detachably mounted on the frame using clamps, while the lower cooling water pipe and the lower drying air pipe are detachably mounted on the support plate using clamps.

[0014] Furthermore, the inner wall of the clamp is equipped with shock-absorbing rubber pads.

[0015] The beneficial effects of the cooling device for aluminum profile processing provided by this utility model are:

[0016] 1. This device features double-sided spraying and air jetting, enabling rapid cooling and drying of aluminum profiles. It effectively improves cooling efficiency and solves the problem of residual moisture on the surface of aluminum profiles, preventing the formation of an aluminum oxide film from the reaction of aluminum and oxygen. This ensures the gloss of the aluminum profile surface, improves the adhesion of subsequent coating processes, and enhances product quality. At the same time, the double-sided spraying allows for 360° cooling of the aluminum profiles without dead angles, resulting in a more uniform overall temperature of the aluminum profiles.

[0017] 2. Grooves are provided along the axial direction on the surface of the conveyor roller assembly, which can effectively reduce the contact area between the roller and the aluminum profile, allowing more cooling water to come into contact with the aluminum profile, thereby further improving cooling efficiency.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0035] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0036] This utility model provides a cooling device for aluminum profile processing, such as... Figures 1 to 4 As shown, the system includes a frame 1 and a conveyor roller assembly 2 mounted on the frame 1 for conveying aluminum profiles. An upper cooling water pipe 3 and a lower cooling water pipe 4 are respectively provided above and below the conveyor roller assembly 2. Multiple water spray nozzles 31 facing the aluminum profiles are installed on both the upper cooling water pipe 3 and the lower cooling water pipe 4. At the discharge end in the conveying direction, an upper drying air pipe 5 and a lower drying air pipe 6 are also provided above and below the conveyor roller assembly 2. Multiple air spray nozzles 51 facing the aluminum profiles are installed on both the upper drying air pipe 5 and the lower drying air pipe 6.

[0037] By adopting the above technical solution, the cooling device of this utility model can spray and aerosol on both the upper and lower sides of the aluminum profile, which can achieve rapid cooling and drying of the aluminum profile, effectively improve cooling efficiency, and effectively solve the problem of residual moisture on the surface of the aluminum profile, avoid the reaction of aluminum with oxygen to form an aluminum oxide film, ensure the gloss of the aluminum profile surface, improve the adhesion of subsequent coating and other processes, and improve product quality. At the same time, the upper and lower double-sided spraying can achieve 360° cooling of the aluminum profile without dead angles, making the overall temperature of the aluminum profile more uniform.

[0038] In this embodiment, the surface of the roller body 21 of the conveying roller group 2 is provided with a groove 211 along the axial direction. The depth of the groove 211 gradually increases from both ends of the roller body 21 towards the center, and the diameter of the roller body 21 gradually decreases from both ends of the roller body 21 towards the center, forming a smooth transition recessed structure. This can effectively reduce the contact area between the roller body 21 and the aluminum profile, so that the cooling water can have a more sufficient contact with the aluminum profile, thereby further improving the cooling efficiency.

[0039] In this embodiment, the surface of the roller body 21 of the conveying roller group 2 is covered with an anti-slip rubber layer 212. The anti-slip rubber layer 212 can effectively enhance the stability of the aluminum profile during the conveying process. While ensuring the stable conveying of the aluminum profile, it further reduces the sliding of the aluminum profile during the conveying process, and ensures uniform cooling and drying effects.

[0040] In this embodiment, a support plate 8 is provided on the frame 1, and the lower cooling water pipe 4 and the lower drying air pipe 6 are both fixed on the support plate 8. Several drainage holes 81 are provided on the support plate 8 to prevent water accumulation.

[0041] In this embodiment, symmetrical limiting guides 82 are provided on both sides of the support plate 8, and a sliding groove 11 matching the limiting guide 82 is provided on the frame 1. The limiting guide 82 is a wedge-shaped structure with a trapezoidal cross-section. The support plate 8 can be detachably installed on the frame 1 through the wedge-shaped engagement of the limiting guide 82 and the sliding groove 11, which facilitates installation, disassembly, maintenance and repair. The inclined guide can automatically correct the position of the support plate 8 and ensure the stability of the support plate 8. In other embodiments, a wear-resistant bushing made of material such as polytetrafluoroethylene can be embedded in the sliding groove 11 to increase its service life.

[0042] In this embodiment, the upper cooling water pipe 3 and the upper drying air pipe 5 are detachably mounted on the frame 1 via clamps 7, and the lower cooling water pipe 4 and the lower drying air pipe 6 are detachably mounted on the support plate 8 via clamps 7. This detachable mounting method facilitates the installation, replacement, and maintenance of the pipes. In this embodiment, the inner wall of the clamps 7 is provided with a shock-absorbing rubber pad (not shown in the figure). The shock-absorbing rubber pad can effectively reduce the vibration of the pipes during operation, reduce noise, and protect the pipes from damage.

[0043] It should be noted that clamp 7 is existing technology, and those skilled in the art should be clear about its structure, principle, and usage, etc., which will not be described in detail here.

[0044] In this embodiment, a water collection tank 9 is provided below the support plate 8. The water collection tank 9 is connected to the upper cooling water pipe 3 and the lower cooling water pipe 4 through a water pump to form a water circulation system, realizing the recycling of water resources and reducing production costs. In this embodiment, a filter screen 91 is provided inside the water collection tank 9. The filter screen 91 is located at the front end of the water pump inlet. The filter screen 91 can filter impurities in the water, ensure the quality of circulating water, and prevent impurities from clogging the water spray nozzles 31.

[0045] In other embodiments, a cooling device may be installed in the water collection tank 9 to cool the cooling water and keep it at a low temperature.

[0046] In this embodiment, a water guide plate 12 is provided on the frame 1. The water guide plate 12 is located between the water collection tank 9 and the support plate 8. The water guide plate 12 is arranged at an angle of 10°-30°. The lower end of the water guide plate 12 faces the water collection tank 9, so as to guide the water after cooling the aluminum profile to flow smoothly into the water collection tank 9.

[0047] In this embodiment, the surfaces of the water guide plate 12 and the support plate 8 are coated with an anti-corrosion coating to prevent corrosion from long-term contact with water, which can effectively extend the service life of the device.

[0048] In this embodiment, the water spray nozzle 31 is an adjustable fan-shaped nozzle. The water spray nozzle 31 is installed on the upper cooling water pipe 3 and the lower cooling water pipe 4 through a quick-connect coupling. Its spray range and angle can be flexibly adjusted according to the specifications, shape and actual cooling requirements of the aluminum profile.

[0049] In this embodiment, the upper drying air pipe 5 and the lower drying air pipe 6 are connected to a compressed air source. The jet nozzle 51 is a flat slit nozzle, which is installed on the upper drying air pipe 5 and the lower drying air pipe 6 via a quick-connect coupling. In this embodiment, the air outlet direction of the jet nozzle 51 forms a 30°-60° angle with the conveying direction of the aluminum profile. The oblique airflow forms a "wind knife effect," which can quickly peel off the water film on the surface of the aluminum profile, thereby effectively shortening the drying time and reducing the amount of compressed air used.

[0050] The present invention provides a cooling device for aluminum profile processing, which integrates the dual functions of "high-efficiency cooling" and "instant drying". It can not only solve the technical requirements of rapid and uniform cooling of aluminum profiles, but also eliminate a series of quality problems (oxidation, water stains, poor adhesion) caused by residual moisture on the surface. The aluminum profiles processed by this device can be obtained with stable dimensions, clean and dry surfaces, and consistent performance, ensuring that the final aluminum profile products meet the requirements of high-precision dimensions, excellent surface quality and long-term durability.

They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0052] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
