The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be understood broadly, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0031] After extrusion molding, metal profiles typically require rapid cooling through a cooling system to stabilize their physical properties and geometry. The quality of the cooling process directly affects the profile's strength, hardness, straightness, and surface quality; therefore, the design and optimization of cooling systems have always been a key focus in the industry. Traditional metal profile cooling methods mainly include air cooling and water cooling. Air cooling uses airflow to cool the surface of the metal profile, but this method has low cooling efficiency and high processing costs. Water cooling, on the other hand, involves directly spraying cooling water onto the surface of the metal profile for rapid cooling, but this method results in uneven cooling and poor cooling and forming quality of the metal profile.

[0032] It should be further explained that traditional spray water cooling systems often fail to achieve uniform cooling, leading to uneven stress distribution within the metal profiles. This can easily cause deformation, cracks, or other defects, affecting product performance. During the cooling process, the metal profiles may become skewed or twisted due to the impact of the cooling water flow or uneven stress, resulting in non-compliance with straightness and dimensional accuracy standards. After cooling, water stains often remain on the surface of the metal profiles. If not removed promptly, these can cause oxidation, corrosion, or surface defects, reducing the product's appearance quality and corrosion resistance. Traditional cooling systems have low water recycling rates, resulting in significant water waste and increasing wastewater treatment costs and environmental burden. With the manufacturing industry's ever-increasing demands for product quality and environmental protection, developing a cooling system that can achieve efficient cooling, prevent metal profile deformation, improve surface quality, and reduce resource waste has become an urgent need for the industry. This technical solution is proposed against this backdrop, aiming to solve the technical bottlenecks in traditional cooling processes and provide a more efficient and environmentally friendly solution for metal profile manufacturing.

[0039] By arranging a plurality of upper cooling water tanks 120 along the metal profile conveying direction, multi-section immersion cooling can be achieved for the metal profile product, the cooling effect is uniform and reliable, the metal profile product with gradually decreasing temperature passes through each upper cooling water tank 120 in turn, and the effect of gradient cooling forming can be achieved, which not only effectively improves the cooling efficiency, but also reduces defects such as deformation and cracking, and the cooling forming effect is good; in addition, by limiting the position of the metal profile from two dimensions through the anti-deviation shaping module 110, the probability of deviation of the metal profile product during cooling advancement can be significantly reduced, the probability of deviation or distortion of the metal profile product can be effectively reduced, thereby effectively ensuring the straightness and dimensional accuracy of the metal profile product, and the cooling forming effect of the metal profile product is stable and reliable; by using compressed air to blow the surface of the metal profile product in all directions through the air pump 210 cooperating with a plurality of air nozzles 220, the residual water stains on the surface of the metal profile product can be quickly removed, the drying effect is uniform and reliable, which not only avoids the oxidation or corrosion of the surface of the metal profile product due to residual water stains, but also improves the appearance quality of the product; the cooling water tank located below the water cooling assembly 100 and the drying assembly 200 can effectively collect the water loss during the cooling forming process, which can reduce the waste of water resources, thereby reducing the cooling cost, reducing the burden of wastewater treatment and environmental burden, and being environmentally friendly and energy-saving.
