Description

Technical Field

[0001] This invention relates to the field of aluminum profile cooling equipment, and in particular to a rapid cooling equipment for aluminum profiles for doors and windows after extrusion molding. Background Technology

[0002] In the field of building doors and windows, aluminum alloy profiles are widely used due to their advantages such as light weight, high strength, and corrosion resistance. They are generally formed using a hot extrusion process, with the extruded profiles reaching temperatures of 480℃~560℃, requiring rapid cooling and quenching to ensure dimensional accuracy and mechanical properties. Currently, aluminum profile cooling is divided into two categories: air cooling and water cooling. However, to meet the requirements of load-bearing, assembly, and thermal insulation, door and window aluminum profiles are mostly irregularly shaped multi-cavity cross-sections, with uneven wall thickness distribution being an inherent characteristic. Existing water cooling equipment has the following drawbacks when cooling aluminum profiles with uneven wall thickness: Existing water-cooling equipment applies a uniform cooling intensity to the entire cross-section of the aluminum profile. Due to the small heat capacity and short heat conduction path of the thin-walled sections, the cooling rate is significantly faster than that of the thick-walled sections. This results in a large temperature gradient within the same cross-section of the profile, leading to uneven internal stress. Consequently, the profile is prone to bending, warping, twisting, and other deformation problems during and after cooling. Furthermore, because the nozzle arrangement angle, spray pressure, and flow rate of existing spray equipment are fixed, they can only achieve uniform spraying and cannot adjust the cooling intensity at different locations based on the wall thickness distribution of the aluminum profile cross-section. Moreover, the circumferential cooling uniformity of the aluminum profile is already affected by nozzle layout and water flow reflection, which, combined with the uneven wall thickness of the profile itself, further amplifies the temperature difference and deformation within the cross-section. Summary of the Invention

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides a rapid cooling device for aluminum profiles for doors and windows after extrusion molding.

[0004] The technical solution is as follows: A rapid cooling device for aluminum profiles for doors and windows after extrusion molding includes a housing. Inside the housing are several equidistantly distributed transport rollers and several equidistantly distributed connecting frames. The housing is equipped with a power module for driving the transport rollers to rotate. Each connecting frame is rotatably connected to a mounting ring. The housing is equipped with a drive module for driving the mounting ring to rotate. The mounting ring is slidably connected to several circumferentially evenly distributed connecting shells. Each connecting shell contains a nozzle. Several sets of equidistantly distributed mounting frames are fixed inside the housing. Each set includes two symmetrically distributed mounting frames. Each set of mounting frames is rotatably connected to a connecting ring. Each mounting frame is equipped with a transmission module for driving the corresponding connecting ring to rotate. Each connecting ring contains a limit ring, which is used to change the movement path of the connecting shell.

[0009] More preferably, it also includes adjusting rings in the same number as the mounting rings. The adjusting rings are rotatably connected to the mounting rings and are threadedly connected to a second threaded rod for fixing the position of the adjusting rings. The adjusting rings are provided with circumferentially evenly distributed limiting grooves, and limiting posts are slidably connected in the limiting grooves.

[0015] By adjusting the rotation of the regulating ring, the position of the nozzle is adjusted according to the size of the aluminum profile, so that the cooling water impacts the surface of the aluminum profile at high speed and vertically, reducing the water film and enhancing convective heat transfer, thereby improving the cooling efficiency.

Detailed Implementation

[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1

[0020] A rapid cooling device for aluminum profiles used in doors and windows after extrusion molding, such as... Figures 1-10 As shown, the device includes an outer shell 1. Inside the outer shell 1, there are several transport rollers 2 and several connecting frames 3 arranged at equal intervals. The outer shell 1 is equipped with a power module for driving the transport rollers 2 to rotate. The connecting frames 3 are rotatably connected to mounting rings 4. The outer shell 1 is equipped with a drive module for driving the mounting rings 4 to rotate. The mounting rings 4 are slidably connected to several circumferentially evenly distributed connecting shells 5. The connecting shells 5 are equipped with nozzles 6. Several sets of mounting frames 7 are fixedly connected at equal intervals inside the outer shell 1. Each set includes two symmetrically distributed mounting frames 7. Each set of mounting frames 7 is rotatably connected to a connecting ring 8. The mounting frames 7 are equipped with a transmission module for driving the corresponding connecting rings 8 to rotate. The connecting rings 8 are equipped with limit rings 9, which are used to change the movement path of the connecting shells 5.

[0021] In the above scheme, the outer shell 1 is an existing device with a water outlet on its lower side; the power module and drive module on the outer shell 1 are also existing devices, and are not shown in the figure. They are selected by the staff according to the actual working conditions during use; the specific number of connecting frames 3 can be selected by the staff according to actual needs. In the figure and text, three sets are shown as an example. Each set includes two connecting frames 3 located on the lower side inside the outer shell 1, and each set of connecting frames 3 is rotatably connected to the corresponding mounting ring 4; six connecting shells 5 on the same mounting ring 4 are shown as an example of circumferentially evenly distributed around them, which are used to improve the heating uniformity and cooling efficiency of the aluminum profile; in this embodiment, the nozzle 6 is fixedly connected to the corresponding connecting shell 5; the symmetrically distributed mounting frames 7 are located on the left and right sides inside the outer shell 1; the transmission module is an existing device and is not shown in the figure. The transmission module has a locking function. When it is not started, the connecting ring 8 is locked and cannot rotate; the limiting ring 9 is located inside the connecting ring 8, and the outer diameter of the limiting ring 9 is smaller than the inner diameter of the connecting ring 8.

[0022] like Figure 10 As shown, the limiting ring 9 is made of a highly elastic hard material, which has excellent resilience and good rigidity and wear resistance.

[0023] like Figures 2-9 As shown, the connecting ring 8 is threaded with several first threaded rods 10 that are evenly distributed in the circumference. The limiting ring 9 is fixed with several connecting blocks 11 that are evenly distributed in the circumference. The connecting blocks 11 are rotatably connected to the corresponding first threaded rods 10. The connecting shell 5 is rotatably connected to a rotating roller 12 and symmetrically distributed rotating wheels 13 on the side near the connecting ring 8. Both the rotating roller 12 and the rotating wheels 13 are in contact with the corresponding limiting ring 9.

[0024] In the above scheme, the number of first threaded rods 10 on the same connecting ring 8 can be selected by the staff according to the actual working conditions. The figure and text both show six as an example. The connecting block 11 is located outside the corresponding limiting ring 9, and the number of connecting blocks 11 is the same as the number of first threaded rods 10. The two rotating wheels 13 on the same connecting shell 5 are symmetrically distributed front and back, and the distance between the two rotating wheels 13 on the same connecting shell 5 is not less than the width of the connecting block 11, so as to avoid the connecting block 11 interfering with the movement of the corresponding rotating wheel 13.

[0025] like Figure 9 and Figure 10 As shown, the rotating roller 12 and the rotating wheel 13 are located on the inner and outer sides of the corresponding limiting ring 9, respectively, and the minimum distance between the rotating roller 12 and the rotating wheel 13 is equal to the thickness of the limiting ring 9, ensuring that the rotating roller 12 and the rotating wheel 13 can always be in contact with the corresponding limiting ring 9 during the rotation of the corresponding mounting ring 4.

[0026] like Figures 5-9 As shown, a liquid storage shell 14 is fixedly connected to one side of the connecting ring 8. A rotating ring 15 is rotatably connected to the liquid storage shell 14. The rotating ring 15 is fixedly connected to the corresponding mounting ring 4. The nozzle 6 is fixedly connected to and connected to a hose. The hose on the nozzle 6 passes through the corresponding rotating ring 15 and is connected to the corresponding liquid storage shell 14.

[0027] In the above scheme, the liquid storage shell 14 is located behind the corresponding connecting shell 5 and is located inside the corresponding connecting ring 8; the rotating ring 15 is located in front of the corresponding liquid storage shell 14 and rotates synchronously with the corresponding mounting ring 4; in this embodiment, cooling water is supplied to the liquid storage shell 14 by the liquid supply device, and the cooling water is sprayed out from the nozzle 6 through the hose.

[0028] The specific workflow of the above scheme is as follows: When this equipment is needed to cool the extruded aluminum profile, the operator changes the shape of all the limiting rings 9 according to the thickness and specific shape of the aluminum profile. The following description uses the example of the lower side of the aluminum profile being thicker than the upper side: The operator activates the front transmission module, which drives the connecting ring 8 to rotate (during this process, the connecting ring 8 drives the front liquid storage shell 14 to rotate synchronously). The connecting ring 8 drives the six first threaded rods 10 on it to rotate, and the first threaded rods 10 drive the corresponding connecting blocks 11 to rotate. In turn, the six connecting blocks 11 on the front drive the front limiting ring 9 to rotate synchronously. After the limiting ring 9 rotates 180°, the operator shuts off the front transmission module and rotates the first threaded rod 10 located on the upper side. This causes the first threaded rod 10 to move downward synchronously during rotation, and the first threaded rod 10 drives the corresponding connecting block 11 to move downward synchronously. The connecting block 11 pushes the upper side of the limiting ring 9 to be recessed inward, thereby changing the shape of the limiting ring 9.

[0029] During the deformation of the limiting ring 9, the limiting ring 9 pushes the upper rotating roller 12 to push the upper connecting shell 5 downward, thereby causing the corresponding nozzle 6 to move downward synchronously, reducing the distance between the nozzle 6 and the central axis of the mounting ring 4. After the shape of the limiting ring 9 is adjusted, the operator stops rotating the first threaded rod 10, and then controls the transmission module to drive the connecting ring 8 to rotate 180° in the opposite direction.

[0030] During the reverse rotation of the front connecting ring 8, the connecting ring 8 drives the corresponding limiting ring 9 to rotate synchronously. During the rotation, the deformed part of the limiting ring 9 squeezes the rotating roller 12 it passes through in sequence, causing the corresponding nozzle 6 to move in sequence toward the central axis of the mounting ring 4. As the limiting ring 9 continues to rotate, the deformed part of the limiting ring 9 gradually loses contact with the rotating roller 12. Thus, under the action of the non-deformed part of the limiting ring 9, the corresponding nozzle 6 is driven to gradually return to its initial position relative to the mounting ring 4. Until the connecting ring 8 rotates 180° in the reverse direction, the deformed part of the limiting ring 9 rotates to the lower side. Then, the operator shuts down the front transmission module and adjusts the shape of the remaining limiting rings 9 in sequence according to the above operation.

[0031] After adjusting the shape of all the limiting rings 9, the staff started the drive module, which drove all the mounting rings 4 to rotate synchronously. The mounting rings 4 drove all the connecting shells 5 on them to rotate, and the connecting shells 5 drove the corresponding nozzles 6, the corresponding rotating rollers 12 and the corresponding two rotating wheels 13 to move synchronously. During this process, the mounting rings 4 drove all the connecting shells 5 to pass through the deformation points of the corresponding limiting rings 9 in sequence, so that all the nozzles 6 moved towards the position close to the central axis of the mounting rings 4 in sequence as the mounting rings 4 rotated (during this process, the mounting rings 4 drove the corresponding rotating rings 15 to rotate). At the same time, the staff delivered cooling water to all the liquid storage shells 14 through the liquid supply device, thereby delivering cooling water to all the nozzles 6.

[0032] After the drive module is started, the staff controls the power module to drive all the transport rollers 2 to rotate, so that all the transport rollers 2 together transport the extruded aluminum profile backward. During the transportation process, the cooling water sprayed by the circumferentially rotating nozzles 6 cools down the aluminum profile. At the same time, during the cooling process, the nozzles 6 automatically move closer to the thick-walled parts of the aluminum profile and relatively farther away from the thin-walled parts, so as to ensure that the cooling water is more concentrated in the thick-walled areas of the aluminum profile, reducing the splashing, atomization and kinetic energy loss of the cooling water after separating from the nozzles 6, and allowing the cooling medium to act more fully on the surface of the profile, thereby applying different cooling intensities to parts with different wall thicknesses and improving the overall cooling uniformity (during this process, the cooling water after heat exchange is discharged from the outlet on the lower side of the outer shell 1).

[0033] After the aluminum profile has finished cooling and left the cooling area, the staff first shut off the liquid supply device to stop supplying cooling water to all liquid storage tanks 14 and nozzles 6; then shut down the drive module to stop the rotation of each mounting ring 4; at the same time, shut down the power module to stop the rotation of the transport roller 2.

[0034] After the equipment has completely stopped, if it is necessary to restore each limiting ring 9 to its initial equidistant state, the operator can reset it in the reverse order of adjustment: first, start the corresponding front transmission module to drive the front connecting ring 8 to rotate 180° forward or backward, so that the deformed part of the limiting ring 9 returns to a position that is easy to operate; then rotate the first threaded rod 10 that was previously adjusted, so that the threaded rod moves upward, driving the corresponding connecting block 11 to move upward, and the limiting ring 9 returns to its original state under the action of the connecting block 11. At the same time, the nozzle 6 that was originally pushed close to the aluminum profile returns to its initial position under the action of the limiting ring 9 contour. Finally, turn off the transmission module to complete the reset, ready for subsequent use.

[0035] Example 2

[0036] Considering that aluminum profiles of different specifications have different outer diameters or cross-sectional dimensions, if all nozzles 6 are always kept in the same position, for larger profiles, the nozzles 6 may be too close to the surface or even collide; while for smaller profiles, the nozzles 6 may be too far from the surface, and the cooling water will be attenuated in speed and have insufficient impact force when it reaches the surface. Therefore, the present invention solves the above problems through the following measures.

[0037] Based on Example 1, such as Figures 2-9As shown, it also includes adjusting rings 16 in the same number as the mounting rings 4. The adjusting rings 16 are rotatably connected to the mounting rings 4. The adjusting rings 16 are threadedly connected to a second threaded rod 161, which is used to fix the position of the adjusting rings 16. The adjusting rings 16 are provided with circumferentially evenly distributed limiting grooves 17. Limiting posts 18 are slidably connected in the limiting grooves 17. The connecting shell 5 is slidably connected to the corresponding nozzle 6. The nozzle 6 is slidably connected to a positioning ring 19. The positioning ring 19 is fixedly connected to the corresponding limiting post 18. The connecting shell 5 is provided with a through groove for the corresponding limiting post 18 to move. A limiting tension spring 20 is fixedly connected between the connecting shell 5 and the corresponding nozzle 6.

[0038] In the above scheme, the adjusting ring 16 is located in front of the corresponding mounting ring 4, and the mounting ring 4 provides axial limiting for the corresponding adjusting ring 16. Under normal conditions, the rear side of the second threaded rod 161 is in contact with and tightly fitted to the front side of the corresponding mounting ring 4, thereby fixing the adjusting ring 16 in this position. The number of upper limit grooves 17 on the same adjusting ring 16 is the same as the number of connecting shells 5 on the corresponding mounting ring 4. The limit groove 17 is a guide groove that extends circumferentially along the adjusting ring 16 and the distance from the bottom of the groove to the central axis of the adjusting ring 16 gradually decreases circumferentially. The limiting post 18 is located in front of the corresponding nozzle 6. Under normal conditions, the distance between the limiting post 18 and the central axis of the corresponding mounting ring 4 is the largest. A one-way limiting structure is provided between the positioning ring 19 and the nozzle 6, so that in the initial state, the positioning ring 19 can only move relative to the nozzle 6 in a direction away from the central axis of the mounting ring 4, and the limiting tension spring 20 is always in a charged state to maintain the relative position of the nozzle 6 and the corresponding positioning ring 19.

[0039] like Figure 7 As shown, a rubber pad is provided on the side of the second threaded rod 161 near the corresponding mounting ring 4 to increase the friction between the two.

[0040] In the above scheme, the rubber pad on the second threaded rod 161 is initially in a compressed state to ensure the stability of the corresponding adjusting ring 16 position.

[0041] like Figures 8-10 As shown, a telescopic rod 21 is fixedly connected to the side of the connecting shell 5 away from the corresponding adjusting ring 16. The telescopic rod 21 passes through the corresponding mounting ring 4 and is slidably connected to it. The telescopic end of the telescopic rod 21 is fixedly connected to the corresponding nozzle 6. A locking device 22 is provided on the fixed part of the telescopic rod 21.

[0042] In the above scheme, the telescopic rod 21 and the locking device 22 thereon are existing devices. The locking device 22 is used to lock the telescopic end of the telescopic rod 21 and fix the telescopic end of the telescopic rod 21 in the extended position. Initially, the locking device 22 does not lock the corresponding telescopic rod 21.

[0043] The specific workflow of the above scheme is as follows: Before adjusting the shape of the limiting ring 9, the staff first changed the initial position of all nozzles 6 according to the size of the aluminum profile to be cooled. This ensures that the cooling water sprayed from the nozzles 6 can impact the surface of the aluminum profile at a high speed, either vertically or nearly vertically, reducing the surface water film, increasing the convective heat transfer coefficient, and thus more effectively removing heat and improving the cooling efficiency of the aluminum profile. The adjustment process is as follows: Rotate the second threaded rod 161 on the front side to separate the second threaded rod 161 from the corresponding mounting ring 4 and release the lock on the front adjusting ring 16. Then rotate the front adjusting ring 16 clockwise. During the rotation, the adjusting ring 16 presses the corresponding limiting post 18 through the limiting groove 17 on it, so that the limiting post 18 moves along the through groove on the corresponding connecting shell 5 towards the direction close to the central axis of the mounting ring 4. The limiting post 18 drives the corresponding nozzle 6 to move relative to the corresponding connecting shell 5 through the corresponding positioning ring 19, and stretches the corresponding limiting spring 20. During the movement of the nozzle 6 relative to the corresponding connecting shell 5, the nozzle 6 drives the telescopic end of the corresponding telescopic rod 21 to move synchronously.

[0044] After adjusting the positions of all the front nozzles 6, the operator stops rotating the adjusting ring 16 and rotates the second threaded rod 161 again, causing the second threaded rod 161 to move backward and squeeze the rubber pad on the second threaded rod 161 during the movement, thereby fixing the adjusting ring 16 in the moved position. Then, the operator uses the locking device 22 to lock the telescopic end of the corresponding telescopic rod 21, thereby fixing the telescopic end of the telescopic rod 21 in the extended state, so that the connecting shell 5 can drive the corresponding nozzles 6 to move synchronously through the corresponding telescopic rod 21.

[0045] After locking the telescopic ends of all the front telescopic rods 21, the staff adjusted the initial positions of the remaining nozzles 6 in sequence according to the above operation. After adjusting the positions of all nozzles 6, the staff determined whether it was necessary to change the shape of all the limiting rings 9 according to the thickness of the aluminum profile, so that the nozzles 6 could further reduce the distance between themselves and the surface of the aluminum profile during the subsequent cooling process, thus ensuring the cooling efficiency of the aluminum profile.

[0046] After the aluminum profile has cooled down, the staff will restore the shape of all the limit rings 9 to their original shape as described above, in preparation for subsequent use.

[0047] Example 3

[0048] Based on Example 2, such as Figure 1 As shown, it also includes a first partition plate 23 and a second partition plate 24. The first partition plate 23 and the second partition plate 24 are both fixed inside the outer shell 1. The first partition plate 23 and the second partition plate 24 together divide the outer shell 1 into three chambers. The three chambers of the outer shell 1 are used to deliver cooling water to the corresponding liquid storage shell 14.

[0049] In the above scheme, the second partition plate 24 is located behind the first partition plate 23; the three chambers inside the outer shell 1 are, from front to back, the first chamber, the second chamber, and the third chamber. In this embodiment, the water outlet of the outer shell 1 is located in the first chamber, the second chamber is used to supply cooling water to the front liquid storage tank 14, the third chamber is used to supply cooling water to the middle liquid storage tank 14, and the liquid supply device supplies cooling water to the rear liquid storage tank 14; the aluminum profile is transported in a front-to-back direction, the front, middle, and rear... The three sets of nozzles 6 are supplied with water by the front, middle, and rear liquid storage tanks 14, respectively. The flow path of the cooling water is as follows: the liquid supply device sends low-temperature cooling water into the rear liquid storage tank 14, and the return water formed after spraying by the rear nozzles 6 enters the third chamber; the return water in the third chamber is transported to the middle liquid storage tank 14, and the return water after spraying by the middle nozzles 6 enters the second chamber; the return water in the second chamber is transported to the front liquid storage tank 14, and the return water after spraying by the front nozzles 6 enters the first chamber and is discharged from the outlet of the outer shell 1. Since the temperature of the cooling water increases after each spray heat exchange, the spray water temperature of the three sets of nozzles 6 decreases sequentially from front to middle to rear. The aluminum profile is first pre-cooled by contacting the higher-temperature cooling water at the front, and then gradually cooled by passing through the lower-temperature cooling water at the middle and rear, thereby reducing the thermal shock during initial cooling and reducing the risk of quenching cracks, deformation, and residual stress in the aluminum profile.

[0050] like Figure 1 As shown, the uppermost side of the first partition plate 23 and the second partition plate 24 is not higher than the upper side of the transport roller 2, so as to avoid the aluminum profile from colliding with the first partition plate 23 and the second partition plate 24 during the movement, and to ensure the integrity of the shape of the first partition plate 23 and the second partition plate 24.
