Description

Technical Field

[0001] This application relates to the field of aluminum profile processing technology, and in particular to a cooling device for industrial aluminum profile extrusion lines. Background Technology

[0002] Currently, aluminum profile extrusion presses are industrial equipment that force aluminum alloy billets through a die to form profiles with specific cross-sectional shapes using high temperature and high pressure. The core process involves placing an aluminum rod heated to 400-500℃ into an extrusion cylinder. A hydraulic system drives the extrusion rod to push the aluminum material through the die orifices. After cooling and shaping, aluminum profiles with complex cross-sections, such as those for doors, windows, tracks, and radiators, are obtained. This equipment consists of an extrusion main unit (die, extrusion rod), a hydraulic power system, a heating device, and an auxiliary traction and straightening mechanism. It features high-efficiency forming (extrudes tens of meters in a single pass), high material utilization (waste can be recycled), and flexible die changing, and is widely used in construction, transportation, electronics, and other fields.

[0003] In existing technology, aluminum alloy billets are extruded through a die to form aluminum profiles with a specific cross-section, and these profiles are hollow. The aluminum profile is initially a high-temperature, soft, continuous strip. After extrusion, it is conveyed on a conveyor track, with fans installed on both sides to accelerate airflow over the surface of the aluminum profile, thereby cooling it.

[0004] Regarding the aforementioned technologies, the inventors believe that when aluminum profiles are cooled by air cooling, the thick-walled parts of the aluminum profile cool slowly, while the thin-walled parts cool quickly, which in turn causes the aluminum profiles to bend. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cooling device for industrial aluminum profile extrusion lines. It solves the technical problem that when aluminum profiles are cooled by air cooling, the thick-walled part of the aluminum profile cools slowly while the thin-walled part cools quickly, which leads to the bending of the aluminum profile.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A cooling device for an industrial aluminum profile extrusion line includes: a frame for supporting the cooling device; guide wheels rotatably mounted on the frame and arranged opposite to each other, with the aluminum profile passing between the two oppositely arranged guide wheels; an adjustment assembly mounted on the frame for adjusting the guide wheels; and a cooling assembly mounted on the frame for cooling the aluminum profile.

[0008] Furthermore, the adjustment assembly includes an adjustment cylinder, which is horizontally mounted on the frame, and the guide wheel is rotatably mounted on the piston rod of the adjustment cylinder.

[0009] Furthermore, the guide wheel is provided with a guide groove, and a supporting inclined surface is formed on the side of the guide wheel near the guide groove, the supporting inclined surface being used to support the aluminum profile.

[0010] Furthermore, the cooling assembly includes a drive motor and fan blades, the fan blades being rotatably mounted on the frame, the drive motor being mounted on the frame, and the output shaft of the drive motor being connected to the fan blades.

[0011] Furthermore, the frame is provided with a ventilation plate, and the ventilation plate has air guide holes, which are spaced apart on the ventilation plate.

[0012] Furthermore, an air blowing pipe is provided on one side of the frame, one end of which extends into the cavity of the aluminum profile. Air blowing holes are provided on the air blowing pipe, and several air blowing holes are spaced apart on the air blowing pipe.

[0013] Furthermore, an adjusting block is installed on the frame, the air blowing pipe is installed on the adjusting block, a slider is provided on the frame, the slider is slidably installed on the frame, the adjusting block is installed on the slider, and a return spring is provided between the slider and the frame, the return spring abutting against the slider and the frame.

[0014] In summary, this application includes at least the following beneficial technical effects of the cooling device for industrial aluminum profile extrusion lines:

[0015] 1. During use, the aluminum profile extruded on the extrusion production line passes between two guide rollers. The adjusting component adjusts the guide rollers to press against the aluminum profile. As the aluminum profile passes through the guide rollers, the cooling component cools the aluminum profile. During the air cooling process, the guide rollers guide the aluminum profile to reduce bending caused by uneven cooling.

[0016] 2. By adjusting the guide groove and support slope on the cylinder and guide wheel, the guide wheel can be made to fit tightly against the aluminum profile, preventing the aluminum profile from bending during the cooling process;

[0017] 3. By installing the air blowing pipe on the adjusting block and the return spring between the adjusting block and the frame, the air blowing pipe can be adapted to aluminum profiles of different lengths. Attached Figure Description

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a cooling device for industrial aluminum profile extrusion lines.

[0026] Reference Figure 1 A cooling device for an industrial aluminum profile extrusion line includes a frame 1, on which guide wheels 2 are mounted, arranged opposite each other. The aluminum profile passes between the two oppositely mounted guide wheels 2. The frame 1 is equipped with an adjustment component 3 and a cooling component 4. The adjustment component 3 is used to adjust the guide wheels 2, and the cooling component 4 is used to cool the aluminum profile.

[0027] The frame 1 is rectangular in the horizontal direction. During use, the formed aluminum profile is conveyed along the length of the frame 1. Guide wheels 2 are arranged opposite each other along the width of the frame 1, and three sets of guide wheels 2 are evenly spaced along the length of the frame 1. During use, the aluminum profile passes between two oppositely arranged guide wheels 2, and the guide wheels 2 guide the aluminum profile to reduce bending during conveying.

[0028] Reference Figure 2To enable the guide wheel 2 to adapt to different types of aluminum profiles, the adjustment assembly 3 includes an adjustment cylinder 31. The adjustment cylinder 31 corresponds to the guide wheel 2, and the piston rod of the adjustment cylinder 31 faces the side closer to the guide wheel 2. The guide wheel 2 is rotatably mounted on the piston rod of the adjustment cylinder 31. In use, the guide wheel 2 moves to a side that is further away from or closer to the guide wheel 2 via the adjustment cylinder 31, thereby limiting the horizontal position of the aluminum profile and preventing the aluminum profile from shifting to either side in the horizontal direction.

[0029] Furthermore, the guide wheel 2 is provided with a guide groove 21, which is generally annular. Supporting inclined surfaces 22 are formed on both sides of the guide wheel 2 on the guide groove 21. When the guide wheel 2 is pressed against the aluminum profile, the supporting inclined surfaces 22 on the guide wheel 2 support the aluminum profile. On the one hand, the supporting inclined surfaces 22 allow the guide wheel 2 to adapt to different types of aluminum profiles; on the other hand, the supporting inclined surfaces 22 support the aluminum profile, reducing the vertical bending of the aluminum profile during transportation.

[0030] Reference Figure 3 The cooling assembly 4 includes a drive motor 41 and a fan blade 42. The drive motor 41 is mounted on the bottom of the frame 1, and the fan blade 42 is mounted on the output shaft of the drive motor 41. In use, the drive motor 41 drives the fan blade 42 to rotate. During the rotation of the fan blade 42, the airflow speed on the surface of the aluminum profile increases, thereby improving the heat dissipation efficiency of the aluminum profile.

[0031] Furthermore, to ensure that the air from the fan blades 42 is fully dispersed on the surface of the aluminum profile, a ventilation plate 43 is provided on the frame 1. The ventilation plate 43 is installed on the side of the frame 1 closest to the fan blades 42, and air guide holes 431 are evenly spaced on the ventilation plate 43. During use, air passes through the air guide holes 431, allowing the aluminum profile to be fully cooled. Further, the cross-section of the air guide holes 431 is conical, and the bottom surface of the conical air guide holes 431 faces the side closest to the fan blades 42. During use, the air is guided by the conical air guide holes 431, which increases the airflow velocity from the fan blades 42, thereby increasing the airflow velocity on the surface of the aluminum profile and improving the cooling efficiency of the aluminum profile.

[0032] In the actual cooling process, only the outer surface of the aluminum profile can be cooled. Since the aluminum profile is a hollow structure, the internal heat can only be discharged through both ends of the aluminum profile, which reduces the cooling efficiency of the aluminum profile and causes the aluminum profile to bend during storage.

[0033] Reference Figure 4Therefore, the frame 1 is equipped with an air blowing pipe 44, which is horizontally positioned and has several air blowing holes 441 spaced apart. In use, an external air supply device is connected to the air blowing pipe 44. After the aluminum profile is extruded from the extrusion line, the air blowing pipe 44 extends from one end of the aluminum profile, and the external air supply device blows air into the aluminum profile through the air blowing pipe 44, thereby improving the airflow inside the aluminum profile and increasing the efficiency of airflow out of the aluminum profile.

[0034] Furthermore, an adjusting block 45 is provided on the frame 1, and the air blowing pipe 44 is mounted on the adjusting block 45. Also, a slider 46 is provided on the frame 1, and a guide rod 461 is provided on the slider 46. The guide rod 461 is vertically oriented, with one end connected to the slider 46 and the other end passing through the adjusting block 45. A nut 462 is threadedly connected to the end of the guide rod 461 passing through the adjusting block 45. Additionally, a support spring 463 is provided between the adjusting block 45 and the slider 46, pressing against the adjusting block 45 and securing the adjusting block 45 against the nut 462. By rotating the nut 462, the height of the adjusting block 45 on the frame 1 can be adjusted, improving the adaptability of the air blowing pipe 44.

[0035] Furthermore, a return spring 47 is provided between the slider 46 and the frame 1, and the return spring 47 is pressed against the slider 46 and the frame 1. In use, as the aluminum profile is extruded from the extrusion line, one end of the aluminum profile presses against the adjusting block 45, and the return spring 47 is compressed, thereby allowing the air blowing pipe 44 to use aluminum profiles of different lengths. After the aluminum profile cools down, the air blowing pipe 44 is removed from the aluminum profile, and then the aluminum profile is removed from the extrusion line. Afterwards, the slider 46 is reset under the action of the return spring 47.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
