Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing equipment technology, and in particular to an aluminum profile extrusion press with a cooling structure. Background Technology

[0002] Aluminum profile extrusion involves placing heated aluminum ingots into an extruder, applying pressure to force the aluminum metal through the extrusion die to form a profile product with the desired cross-sectional shape. The extruded aluminum profiles are extremely hot and require rapid cooling to ensure good microstructure and mechanical properties, while maintaining dimensional accuracy and surface quality. Therefore, aluminum profile extruders are typically equipped with a discharge cooling system for online quenching and cooling of the high-temperature extruded aluminum profiles. Currently, the cooling systems of aluminum profile extruders are primarily water-cooled. Water-cooled systems cool the aluminum profiles by immersing them in a cooling water tank, achieving rapid temperature reduction and representing the most widely used online cooling method for aluminum profile extrusion.

[0003] The cooling water channels of existing aluminum profile extrusion presses are mostly straight-through layouts. The unidirectional flow of cooling water causes intense heat exchange in the inlet section and a decrease in temperature rise in the outlet section. The uniformity of cooling along the conveying direction is seriously unbalanced, which can easily lead to residual stress and deformation of the profile. At the same time, the cooling water is discharged directly and cannot be recycled, which wastes resources and increases costs. Summary of the Invention

[0020] The aluminum profile extrusion press with a cooling structure disclosed in this invention is mainly used in scenarios where straight water channels result in cold inlet and hot outlet, uneven cooling causes deformation, and the cooling water is discharged directly without circulation, resulting in significant waste.

[0022] Reference Figures 1-7 In a preferred embodiment, the gradient serpentine cooling module 8 further includes: Multiple serpentine cooling water pipes 806 are arranged at equal intervals inside the cooling box 7. A circulating pump 12 is arranged at equal intervals on one side of the outside of the cooling box 7.

One end of the water outlet pipe 814 is fixedly connected to the water inlet of the circulating cylinder 801.

[0023] Reference Figures 1-7 In a preferred embodiment, the gradient serpentine cooling module 8 further includes: Multiple cross support frames 16 are fixedly connected to the inside of multiple water outlet pipes 814. A hollow rotating tube 815 is connected to one side of each of the multiple cross support frames 16 via a bearing. A spiral blade 816 is fixedly connected to one end of each of the multiple hollow rotating tubes 815. A cross lifting rod 818 is slidably connected to one side of each of the multiple hollow rotating tubes 815. A cross cleaning brush plate 817 is fixedly connected to one side of each of the multiple cross lifting rods 818. Multiple compression springs 17 are fixedly connected to one side of multiple cross lifting rods 818, and the other side of the compression springs 17 is fixedly connected to one side of the interior of the hollow rotating tube 815.

[0024] Reference Figures 1-7 In a preferred embodiment, the gradient serpentine cooling module 8 further includes: Multiple temperature sensors 808 are equidistantly arranged on one side of the cooling box 7. Two sliding ports are symmetrically opened on the outside of multiple circulating cylinders 801. The same sieve plate 810 is slidably connected inside the two sliding ports on the same circulating cylinder 801. Two sealing slide plates 18 are symmetrically fixedly connected to one side of the sieve plate 810. Multiple U-shaped support plates 15 are symmetrically and fixedly connected to the outside of multiple circulating cylinders 801. Two guide cylinders 812 are fixedly connected to both sides of the sieve plate 810. The two ends of the guide cylinders 812 are slidably connected to one side of the U-shaped support plate 15. Vibration springs 813 are fixedly connected at equal distances to the opposite side of the sieve plate 810 and the U-shaped support plate 15. The vibration springs 813 are located outside the guide cylinders 812.

[0025] Reference Figures 1-7 In a preferred embodiment, the gradient serpentine cooling module 8 further includes: Multiple supply pipes 811 are fixedly connected to the clean water outlet of multiple circulation cylinders 801 respectively. Condensers 802 are equidistantly arranged on one side of the tooling base plate 1. One end of the supply pipe 811 is fixedly connected to the water inlet of the condenser 802. The water inlet of the circulation pump 12 is fixedly connected to the water outlet of the condenser 802 through the circulation pipe 803. Multiple electronic flow valves 804 are respectively installed on the outside of multiple circulation pipes 803, and guide soft cloths 807 are installed inside the inlet and outlet of the cooling box 7.

[0026] Specifically, after the high-temperature aluminum profile is extruded and output from the extrusion die 6, it is carried by the conveyor roller 14 through the cooling box 7. The guide cloth 807 at the inlet and outlet is used to reduce the splashing of cooling water. The gradient serpentine circulation cooling module 8 undertakes the main cooling function. The circulation pump 12 pumps the cooling water through the water blower 809 into multiple serpentine cooling water pipes 806. The cooling water flows in a serpentine manner in the pipes, extending the heat exchange path. The cooling box 7 is divided into multiple cooling zones by two partition plates 805 with conveying ports. Each zone, in conjunction with the electronic flow valve 804, independently adjusts the water flow to achieve gradient cooling along the conveying direction. The cooling water, after absorbing heat and heating up, enters the circulation cylinder 801 through the water outlet pipe 814. The flow impact spiral blades 816 drive the hollow rotating tube 815 to rotate, which in turn drives the cross cleaning brush 817 to continuously scrape the surface of the sieve plate 810, removing attached impurities and preventing filter pore blockage. The compression spring 17 provides elastic pre-tightening force to ensure that the brush plate always fits the sieve plate 810. At the same time, the sieve plate 810 generates high-frequency micro-vibration under the action of the vibration spring 813. The two work together to improve the filtration and anti-clogging ability. The filtered clean cooling water is sent to the condenser 802 for cooling through the supply pipe 811, and then sent back to the serpentine cooling water pipe 806 through the circulation pipe 803 and the circulation pump 12 to complete the closed-loop circulation. The temperature sensor 808 monitors the temperature of each area in real time, and the control display panel 5 displays the temperature centrally and allows the operator to monitor and adjust it. In specific application scenarios, the present invention arranges multiple serpentine cooling water pipes 806 at equal intervals in the cooling box 7, which are divided into independent temperature control zones by the partition plate 805. With the help of the electronic flow valve 804, the flow rate of each circulation pipe 803 is adjusted independently to achieve gradient cooling along the conveying direction. The inlet section is moderately cooled, the middle section is enhanced, and the outlet section is precisely controlled, so that the aluminum profile obtains a uniform and gradual cooling path, effectively solving the problem of temperature difference imbalance and residual stress deformation of profile caused by the cold inlet and hot outlet of the traditional straight water channel. Meanwhile, a closed-loop circulation system is formed by the circulation pump 12, the circulation cylinder 801, the condenser 802 and the circulation pipe 803. The cooling water that has absorbed heat and been heated enters the circulation cylinder 801 through the outlet pipe 814. After filtration and purification, it is sent to the condenser 802 for cooling through the supply pipe 811. Then it is pumped back to the serpentine cooling water pipe 806 by the circulation pump 12 to continue to participate in cooling. The entire process is not discharged to the outside, which greatly reduces water consumption and wastewater treatment costs. In addition, the connection between the water outlet pipe 814 and the circulating cylinder 801 integrates an active scraping structure consisting of a spiral blade 816, a hollow rotating pipe 815, a cross lifting rod 818, a compression spring 17, and a cross cleaning brush 817. The cleaning brush is driven by the kinetic energy of the cooling water flow to continuously rotate and scrape the sieve plate 810 to remove impurities such as oxide scale and metal shavings. At the same time, the sieve plate 810 vibrates under the action of the vibration spring 813, causing impurities with weak adhesion to fall off on their own. The compression spring 17 provides elastic pre-tightening force, so that the cleaning brush adapts to the surface of the sieve plate 810. Even if the sieve plate 810 undergoes slight deformation or displacement, the cleaning effect remains reliable.

[0027] Reference Figure 1 and Figure 8 In a preferred embodiment, the cooling auxiliary module 9 further includes: Multiple electric telescopic rods 902 are fixedly connected to one side of multiple tooling blocks 901 respectively, and the driving end of the multiple electric telescopic rods 902 is provided with the same hollow air suction frame 903; Two partitions 904 are fixedly connected at equal intervals to the inside of the hollow air intake frame 903.

[0028] Reference Figure 1 and Figure 8 In a preferred embodiment, the cooling auxiliary module 9 further includes: Multiple suction frames 905 are equidistantly arranged on one side of the hollow suction frame 903, and a suction pump 908 is provided on one side of each of the multiple suction frames 905. Multiple straws 906 are fixedly connected to one side of multiple suction frames 905, and the suction end of the suction pump 908 is fixedly connected to one end of the straws 906.

[0029] Reference Figure 1 and Figure 8 In a preferred embodiment, the cooling auxiliary module 9 further includes: Multiple air valves 907 are respectively located on the outside of multiple suction tubes 906.

[0030] Specifically, the cooling auxiliary module 9 works synchronously above the cooling box 7. The electric telescopic rod 902 on the tooling block 901 drives the hollow suction frame 903 to rise and fall, adjusting the suction distance between the suction frame 905 and the aluminum profile inside the cooling box 7. The suction pump 908 extracts the water vapor and heat generated during the cooling process through the suction pipe 906 and the suction frame 905, preventing water vapor from condensing into water droplets on the inner wall of the cooling box 7 and falling onto the surface of the high-temperature aluminum profile, causing uneven cooling or surface defects. The partition 904 set inside the hollow suction frame 903 divides the suction area into multiple independent sections. With the help of multiple suction frames 905 and the air valves 907 set outside the suction pipe 906, independent suction control of different cooling areas can be achieved. In specific application scenarios, the present invention provides a cooling auxiliary module 9 above the cooling box 7, consisting of a hollow suction frame 903, a suction frame 905, a suction pump 908, a suction pipe 906, and a valve 907. This module can actively extract water vapor and heat generated during the cooling process, preventing water vapor from condensing into water droplets on the inner wall of the cooling box 7 and falling onto the surface of the high-temperature aluminum profile, thus preventing surface defects caused by localized sudden cooling. The electric telescopic rod 902 can adjust the suction distance to adapt to different profile specifications. The partition 904 divides the suction area into multiple independent sections, which, together with the valve 907, enables differentiated suction control for different cooling areas, further improving the accuracy of the cooling process and the surface quality of the profile.

[0031] Reference Figure 1 Figure 2 In a preferred embodiment, it further includes: The control display panel 5 is located on one side of one of the tooling panels 2.

[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, it further includes: Multiple guide rails 3 are equidistantly arranged on opposite sides of two tooling panels 2; The guide mechanism 10 is slidably connected inside multiple guide rails 3.

[0033] Reference Figure 1 and Figure 3 In a preferred embodiment, it further includes: A conveyor support plate 13 is disposed inside the cooling box 7, and conveyor rollers 14 are disposed at equal intervals on one side of the conveyor support plate 13.

[0034] Working principle: After extrusion molding, the high-temperature aluminum profile is output through the extrusion die 6 and carried by the conveyor roller 14 through the cooling box 7. The guide cloth 807 at the inlet and outlet is used to reduce the splashing of cooling water. The gradient serpentine circulation cooling module 8 undertakes the main cooling function. The circulation pump 12 pumps the cooling water through the water blower 809 into multiple serpentine cooling water pipes 806. The cooling water flows in a serpentine manner in the pipes, extending the heat exchange path. The cooling box 7 is divided into multiple cooling zones by two partition plates 805 with conveyor ports. Each zone is independently controlled by an electronic flow valve 804. The water flow rate is adjusted to achieve gradient cooling along the conveying direction. The cooling water, after absorbing heat and heating up, enters the circulating cylinder 801 through the outlet pipe 814. The water flow impacts the spiral blades 816, driving the hollow rotating tube 815 to rotate. This causes the cross cleaning brush 817 to continuously scrape the surface of the sieve plate 810, removing attached impurities and preventing filter pore blockage. The compression spring 17 provides elastic pre-tightening force to ensure that the brush always fits the sieve plate 810. At the same time, the sieve plate 810 generates high-frequency micro-vibration under the action of the vibration spring 813. The two work together to improve the filtration and anti-clogging ability. The filtered clean cooling water is sent to the condenser 802 for cooling through the supply pipe 811, and then returned to the serpentine cooling water pipe 806 through the circulation pipe 803 and the circulation pump 12 to complete the closed-loop circulation. At the same time, the cooling auxiliary module 9 works synchronously above the cooling box 7. The electric telescopic rod 902 on the tooling block 901 drives the hollow suction frame 903 to rise and fall, adjusting the suction distance between the suction frame 905 and the aluminum profile inside the cooling box 7. The suction pump 908 uses the suction pipe 906 and the suction frame 905 to pump the water generated during the cooling process. Steam and heat are extracted to prevent water vapor from condensing into water droplets on the inner wall of the cooling box 7 and falling onto the surface of the high-temperature aluminum profile, causing uneven cooling or surface defects. The partition 904 inside the hollow suction frame 903 divides the suction area into multiple independent zones. With the help of multiple suction frames 905 and air valves 907 on the outside of the suction pipe 906, independent suction control of different cooling zones can be achieved. The temperature sensor 808 monitors the temperature of each zone in real time, and the control display panel 5 displays the temperature centrally for operators to monitor and adjust.
