[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] This utility model provides two technical solutions:

[0024] Figure 1-Figure 5The first embodiment is shown: a water-cooled quenching device for aluminum alloy profiles, including a feeding conveyor 1, a quenching mechanism for quenching aluminum alloy profiles is provided downstream of the feeding conveyor 1, and a unloading conveyor 5 is provided downstream of the quenching mechanism, and the quenching mechanism includes: a conveying component 2, the conveying component 2 includes a frame 21; a lifting component 3, which is arranged inside the frame 21, and the lifting component 3 includes a support plate 31 installed on the inner wall of the frame 21 near the middle position, and a hydraulic cylinder 32 is fixedly installed on the bottom surface of the support plate 31, and the telescopic end of the hydraulic cylinder 32 slides through the bottom surface of the support plate 31 and extends upward, and the telescopic end of the hydraulic cylinder 32 is installed with a quenching pool 33; a filtering component 4, which is arranged on the outer surface of the quenching pool 33, and the filtering component 4 includes a filter pool 41, and a filter screen 43 is provided inside the filter pool 41.

[0025] Side panels 22 are symmetrically mounted on the inner wall of the frame 21 near the top. Multiple drive rollers 23 are rotatably mounted between the two side panels 22. A first sprocket assembly 24, consisting of a sprocket and chain, is positioned between the left ends of the multiple drive rollers 23. A motor 25 is mounted on the top surface of the frame 21. A second sprocket assembly 26, consisting of a sprocket and chain, is positioned between the output end of the motor 25 and the right end of one of the drive rollers 23. The motor 25 rotates in conjunction with the second sprocket assembly 26, driving one of the drive rollers 23 to rotate. The multiple drive rollers 23 rotate synchronously via the first sprocket assembly 24.

[0026] The width and length of the inner cavity of the quenching pool 33 are greater than the length of the side plate 22 and the length of the drive roller 23. The quenching pool 33 is arranged directly below the drive roller 23. Guide rods 34 are fixedly installed on the bottom surface of the quenching pool 33 near the four corners. The outer surface of the guide rod 34 slides through the top surface of the support plate 31 and extends downward. The hydraulic cylinder 32 is operated, and its telescopic end pushes the quenching pool 33 up or down. When the aluminum alloy profile needs to be quenched, the hydraulic cylinder 32 pushes the quenching pool 33 up, so that the profile located on the drive roller 23 is immersed in the water in the quenching pool for quenching. The guide rods 34 at the bottom surface of the quenching pool 33 near the four corners slide on the support plate 31 to ensure the stability of the quenching pool 33 when it is raised or lowered.

[0027] Figure 1-Figure 5 A second embodiment is shown, which mainly differs from the first embodiment in that the filter tank 41 is arranged on the right side of the frame 21, and a connecting plate 42 is symmetrically installed on the left side of the filter tank 41, and the connecting plate 42 is fixedly connected to the right side of the quenching tank 33.

[0028] A suction pump 44 is installed on the front side of the filter tank 41. The water inlet of the suction pump 44 is installed with a suction pipe 45 connected to the front side of the quenching tank 33. The water outlet of the suction pump 44 passes through the front surface of the filter tank 41 and extends to the inside. The height of the water outlet of the suction pump 44 is higher than the filter screen 43.

[0029] A circulation pump 46 is installed at the rear of the filter tank 41. A circulation pipe 47 is installed at the outlet of the circulation pump 46, connecting to the rear of the quenching tank 33. The water inlet of the circulation pump 46 penetrates the rear surface of the filter tank 41 and extends into the interior. The height of the water inlet of the circulation pump 46 is lower than that of the filter screen 43. The suction pump 44 operates to draw water from the quenching tank 33 into the filter tank 41 through a suction pipe 45. The water is filtered through the filter screen 43 inside the filter tank 41 to remove impurities. The circulation pump 46 returns the filtered water to the quenching tank 33 through the circulation pipe 47, thus recycling the quenching water.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, the aluminum alloy profile to be quenched is first transported to the conveyor assembly 2 via the loading conveyor 1. The motor 25 in the conveyor assembly 2 is started, driving one of the drive rollers 23 to rotate through the second sprocket assembly 26. Then, multiple drive rollers 23 rotate synchronously under the action of the first sprocket assembly 24, and the profile is smoothly transported to the top of the quenching pool 33. Then, the hydraulic cylinder 32 in the lifting assembly 3 works, pushing the quenching pool 33 up, so that the profile is immersed in the water in the quenching pool for quenching. The guide rod 34 slides on the support plate 31 to ensure the stable lifting of the quenching pool 33. During the quenching process, impurities such as oxide scale generated on the surface of the profile enter the water, and at this time, the filter assembly 4 begins to work. The suction pump 44 draws the water from the quenching pool 33 into the filter pool 41 through the suction pipe 45. When the water passes through the filter screen 43, impurities such as oxide scale are intercepted. Then, the circulating pump 46 returns the filtered water to the quenching tank 33 through the circulating pipe 47, realizing the recycling of the quenching water, ensuring that the quenching water is always kept clean, and providing a good quenching environment for the profiles. Finally, the quenched profiles are transported out by the unloading conveyor 5.
