It includes a gantry frame with lifting mechanisms on both sides of its outer surface. An upper air guide device is located at the lower part of the two lifting mechanisms. A fan is located at the upper end of the gantry frame, and the output port of the fan is connected to the air inlet of the upper air guide device.

Description

Technical Field

[0001] This invention relates to the technical field of heat treatment equipment for aluminum alloy profiles, and particularly to an adjustable quenching equipment for aluminum profiles. Background Technology

[0002] After extrusion molding, aluminum profiles require quenching to refine the metallographic structure, eliminate internal stress, and improve mechanical strength and dimensional stability. This is a core process in the deep processing of aluminum profiles, and the uniformity and stability of the quenching process directly determine the precision, strength, and service life of the finished aluminum profile. Currently, most mainstream online quenching equipment for aluminum profiles in the industry adopts a single air-cooling or single water mist spray cooling structure, which has many technical defects in actual production applications and is difficult to adapt to the production needs of high-precision, complex cross-section aluminum profiles.

[0003] Existing quenching equipment generally adopts a fixed air guide and spray structure, with a single air supply method, mostly vertical direct blowing or single-sided air supply mode. It cannot achieve full coverage cooling of the entire area of ​​the aluminum profile, including the edges, corners and gaps. This easily leads to uneven cooling rates in different parts of the aluminum profile, with significant temperature differences between thick and thin wall areas, and between the center and the edge areas. This results in residual stress, causing quality defects such as bending, twisting and deformation of the profile, and significantly reducing the product qualification rate. At the same time, the air mist mixing effect of traditional equipment is poor. The water mist can only rely on natural airflow to diffuse, resulting in uneven distribution of the cooling medium and poor quenching consistency, which cannot meet the performance requirements of high-end aluminum profiles.

[0004] Based on the shortcomings of the existing technology, there is an urgent need to develop an adjustable, uniformly cooled aluminum profile quenching equipment that combines energy saving and environmental protection. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, a composite air supply system is formed by the vertical high-pressure air curtain of the air knife component of the upper air guide device and the inclined air supply frame of the hook-shaped air supply frame. Combined with the intermittent air supply mechanism of the lower air guide device, the aluminum profile is cooled by bidirectional air blowing from top to bottom and without blind spots. At the same time, the arc-shaped plate diversion structure of the first and second diversion components completely disperses the concentrated airflow, achieves uniform airflow distribution, avoids the problem of excessively high or low local wind speed, effectively balances the cooling rate of different wall thicknesses and positions of the aluminum profile, effectively avoids the generation of residual stress, prevents profile deformation and twisting, and significantly improves the dimensional accuracy and mechanical property consistency of the aluminum profile after quenching.

[0017] 2. In this invention, the atomizing nozzle is integrated into the lower part of the upper air guide device. The high-speed directional airflow carries water mist to evenly cover the surface of the aluminum profile, replacing the traditional single spray or air cooling mode. This achieves air-mist synergistic quenching. The airflow can quickly drive the water mist to penetrate into the fine structure of the profile surface, improving the adhesion of the cooling medium. This ensures the rapid quenching cooling effect while avoiding the profile cracking problem caused by excessive cooling with single water cooling, greatly improving the efficiency of quenching operation and the quality of finished products.

[0018] 3. In this invention, the air delivery mechanism of the lower air guide device and the air guide component form a closed-loop airflow circulation structure, which can use the negative pressure of the airflow to draw in external air for replenishment, and at the same time reintroduce the unused return airflow into the inner cavity of the second conveyor frame for recycling, effectively improving the airflow utilization rate, reducing the energy consumption output of the second fan and the first fan, and reducing the production cost of long-term operation of the equipment.

[0022] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0025] Example 1, see Figure 1 - Figure 18 As shown, this embodiment discloses an adjustable aluminum profile quenching equipment, including: a gantry frame 1, with lifting mechanisms 2 on both sides of the outer surface of the gantry frame 1, and an upper air guide device 4 for outputting upper composite airflow and spraying water mist at the lower part of the two lifting mechanisms 2. The lifting mechanisms 2 are used to drive the upper air guide device 4 to rise and fall vertically to adjust the quenching height. A fan 3 is provided at the upper end of the gantry frame 1 to provide air supply to the upper air guide device 4. The output port of the fan 3 is connected to the air inlet of the upper air guide device 4. A lower air guide device 5 is fixedly installed on the ground below the upper air guide device 4 to output uniform airflow upwards. A roller conveyor component 6 is provided at the upper part of the lower air guide device 5 to continuously feed the aluminum profile to be quenched. A fan 7 is provided at the lower part of the lower air guide device 5 to supply airflow to the lower air guide device 5. The fan 7 is fixedly installed in a pit below the ground.

[0026] Specifically, during the quenching process of aluminum profiles, the aluminum profiles are fed into the upper conveying station from one side of the roller conveyor component 6 and are conveyed and discharged along the roller conveyor component 6. During the conveying of the aluminum profiles, the first fan 3 and the second fan 7 start air supply simultaneously. The airflow output by the first fan 3 and the second fan 7 is guided by the upper air guide device 4 and the lower air guide device 5 respectively and blown onto the surface of the moving aluminum profiles. At the same time, the external water supply component introduces cooling water into the upper air guide device 4. The cooling water is atomized by the built-in structure of the upper air guide device 4. The atomized water mist acts on the surface of the aluminum profiles with the directional airflow output by the upper air guide device 4, realizing the rapid quenching and cooling process of the aluminum profiles.

[0027] Furthermore, when the upper air guide device 4 needs to be installed, disassembled, or routinely maintained, the operator can drive the upper air guide device 4 to make vertical lifting movements by operating the lifting mechanisms 2 on both sides, thereby adjusting the working height and disassembly / removal position of the upper air guide device 4. After the upper air guide device 4 is installed or maintained, it is locked and positioned by the fixing pins configured in the lifting mechanism 2, so as to firmly fix the upper air guide device 4 in the preset working position on the upper inner side of the gantry frame 1, ensuring the stability of the structure during equipment operation.

[0028] To achieve uniform air cooling and precise water mist spray quenching of the upper part of the aluminum profile, and to improve the uniformity and stability of the quenching and cooling process, see [reference needed]. Figure 4As shown, the upper air guide device 4 includes a mounting frame 41. An upper air guide mechanism 42 is provided in the middle of the mounting frame 41. The upper two sides of the outer surface of the upper air guide mechanism 42 are fixedly connected to the lower ends of the two lifting mechanisms 2 respectively. A conveying pipe 43 is provided on both sides of the lower part of the mounting frame 41. Multiple atomizing nozzles 44 are provided on the side of the outer surface of the two conveying pipes 43 that are close to each other.

[0029] Specifically, after the aluminum profile is conveyed to the upper quenching station of the roller conveyor component 6, the high-pressure airflow output by the fan 3 enters the inner cavity of the upper air guide mechanism 42, and after being guided by the upper air guide mechanism 42, it is conveyed downward to the aluminum profile working area of ​​the roller conveyor component 6. At the same time, the external water supply component continuously introduces high-pressure cooling water into the two conveying pipes 43. The cooling water in the conveying pipes 43 is atomized by multiple atomizing nozzles 44 and sprayed out to form a uniform water mist.

[0030] Furthermore, after the cooling water is transported through the conveying pipe 43 and atomized into fine water mist particles by the atomizing nozzle 44, it is precisely applied to the surface of the aluminum profile on the roller conveying component 6 under the guidance of the directional high-speed airflow output by the upper air guide mechanism 42. The aluminum profile is rapidly quenched and cooled in all directions through the combination of air and mist, ensuring the quenching effect of the aluminum profile.

[0031] Furthermore, both ends of the conveying pipe 43 are provided with water inlet interfaces for connection with external water conveying components.

[0032] To divert and guide the airflow entering the upper air guide mechanism 42, achieving uniform airflow distribution and avoiding uneven quenching of the aluminum profile due to concentrated local wind speeds, see [reference needed]. Figure 5 As shown, the upper air guide mechanism 42 includes a conveying component 421. The upper air inlet of the conveying component 421 is connected to the output port of the fan 3. A diverter 422 is provided in the middle of the conveying component 421. The diverter 422 is located below the air inlet of the conveying component 421. An air knife 423 is provided at the lower part of the conveying component 421.

[0033] Specifically, the high-pressure airflow output by the fan 3 enters the inner cavity of the conveyor 421 through the air inlet at the top. After entering the inner cavity of the conveyor 421, the airflow first contacts the middle diverter 422. The diverter 422 diverts and disperses the concentrated airflow through its diversion structure, and evenly distributes the single concentrated airflow to the left and right sides of the inner cavity of the conveyor 421, thus achieving a preliminary uniform distribution of the airflow.

[0034] Furthermore, the airflow after being diverted by the diverter 422 is divided into two paths. One part of the airflow is transported downward along the inner wall of the conveyor 421 and output from the lower air outlet of the conveyor 421. The other part of the airflow is directed into the interior of the air knife 423 and output as a high-pressure air curtain through the air knife 423, thereby achieving zoned differentiated air supply cooling.

[0035] To achieve layered and zoned air supply, a composite air supply structure is formed, consisting of a central high-pressure air curtain and inclined air supply on both sides, expanding the upper air-cooled coverage area. (See [link to relevant documentation]). Figure 6 and Figure 7 As shown, the conveying component 421 includes a conveying frame 4211. Mounting plates 4212 are provided on both sides of the lower part of the conveying frame 4211. Multiple hook-shaped air supply frames 4213 are provided on the lower part of the two mounting plates 4212. The inner cavity of the multiple hook-shaped air supply frames 4213 communicates with the inner cavity of the conveying frame 4211.

[0036] Specifically, the high-pressure airflow introduced into the inner cavity of the conveying frame 4211 by the fan 3 is divided into two conveying paths after being diverted by the diverter 422. One airflow flows into the air knife 423 and is discharged from it, while the other airflow is diverted to the areas on both sides of the conveying frame 4211 and finally blown out by the lower air outlet of the multiple hook-shaped air supply frames 4213 arranged symmetrically on both sides.

[0037] Furthermore, the hook-shaped air supply frame 4213 adopts a hook-shaped structure design, with its lower air outlet arranged at an angle downwards, so that the airflow output by multiple hook-shaped air supply frames 4213 is blown out evenly in an angled downwards state, which can accurately cover the two sides of the aluminum profile. Combined with the vertical air supply of the middle air knife 423, it can achieve all-round air supply and cooling of the upper part of the aluminum profile without dead angles.

[0038] To improve airflow uniformity through a multi-stage arc-shaped flow splitting structure, completely eliminate airflow turbulence and velocity differences, and ensure stable air delivery, see [reference needed]. Figure 8 As shown, the flow divider 422 includes two flow divider plates 4221, which are fixedly installed in the middle of the inner cavity of the conveyor frame 4211. Two flow divider plates 4222 are fixedly installed on the inner surface of the conveyor frame 4211 between the two flow divider plates 4221. Two flow divider plates 4223 are fixedly installed on the inner surface of the conveyor frame 4211 between the two flow divider plates 4222.

[0039] Specifically, the high-pressure airflow entering the inner cavity of the first conveyor frame 4211 first contacts the outer surfaces of the two first diverter plates 4221 and the two second diverter plates 4222. Since the first diverter plate 4221 and the second diverter plate 4222 are both outwardly extending arc-shaped plate structures, they can perform primary diversion of the concentrated airflow, directing most of the airflow to the areas on both sides of the inner cavity of the first conveyor frame 4211, while the remaining small portion of the airflow passes vertically through the gap between the two second diverter plates 4222.

[0040] Furthermore, the airflow passing through the gap of the second diverter plate 4222 is diverted again. Part of the airflow is directly transported downward through the gap between the two third diverter plates 4223, while the other part of the airflow contacts the arc-shaped surfaces of the two third diverter plates 4223. The third diverter plate 4223 adopts the same arc-shaped structure and differentiated size design as the first diverter plate 4221 and the second diverter plate 4222, which can perform secondary precise diversion of the remaining airflow and guide the residual concentrated airflow back to both sides of the inner cavity of the first conveyor frame 4211. The airflow is evenly distributed throughout the entire area through the multi-stage diversion structure.

[0041] To complement the hook-shaped air supply frame 4213 and form a composite air supply system, a central high-pressure air curtain is used to enhance the cooling effect in the central area of ​​the aluminum profile and improve the overall quenching uniformity. (See [link to relevant documentation]). Figure 9 As shown, the air knife component 423 includes a mounting frame 4231, which is fixedly installed on the lower part of the conveying frame 4211. The mounting frame 4231 is located between multiple hook-shaped air supply frames 4213 on both sides. The inner cavity of the mounting frame 4231 communicates with the inner cavity of the conveying frame 4211. Multiple air knives 4232 are provided on the lower part of the mounting frame 4231.

[0042] Specifically, after the airflow in the inner cavity of the conveying frame 4211 is diverted, most of it is output from the hook-shaped air supply frames 4213 on both sides, and the remaining airflow flows into the inner cavity of the mounting frame 4231. Finally, it is sprayed vertically downward at high speed by multiple air knives 4232. The high-pressure air curtain output by the air knives 4232 acts vertically on the central area of ​​the aluminum profile on the roller conveying component 6. Together with the airflow blown out at an angle by the hook-shaped air supply frames 4213 on both sides, it carries the water mist formed by the conveying pipe 43 and the atomizing nozzle 44, and acts on the surface of the aluminum profile in all directions.

[0043] Furthermore, the combination of a central vertical high-pressure air curtain and inclined air supply on both sides allows water mist and airflow to mix fully and evenly cover the entire surface of the aluminum profile, effectively improving the consistency and efficiency of quenching and cooling of the aluminum profile, and ensuring the forming quality and performance stability of the aluminum profile after quenching.

[0044] Example 2 further improves upon Example 1 by modifying the lower air guide device 5. This is to achieve simultaneous air cooling and water mist circulation replenishment for quenching of the lower aluminum profile, while optimizing the lower airflow circulation and wastewater recovery structure to enhance the overall quenching adaptability and environmental friendliness of the equipment. (See [link to example 1]). Figure 10 and Figure 11 As shown, the lower air guide device 5 includes a second mounting bracket 51, which is fixedly installed on the ground. A lower air guide mechanism 52 is provided in the middle of the second mounting bracket 51. The lower air inlet of the lower air guide mechanism 52 is connected to the output port of the second fan 7. An air conveying mechanism 53 is provided in the upper part of the lower air guide mechanism 52.

[0045] Specifically, after the fan 2 7 starts, the high-pressure airflow output is drawn into the inner cavity of the lower air guide mechanism 52 through the lower air inlet. After being diverted and guided by the lower air guide mechanism 52, it is blown out directionally by the upper air supply mechanism 53. The airflow acts upward from the lower part of the aluminum profile and forms a cooling structure with the air supply of the upper air guide device 4, which quenches and cools the lower part of the aluminum profile.

[0046] Furthermore, the air supply mechanism 53 can not only directionally guide the airflow inside the lower air guide mechanism 52 and perform precise air delivery, but also actively introduce external air into the inner cavity of the lower air guide mechanism 52 by utilizing the negative pressure of the airflow to achieve airflow circulation and replenishment, thereby improving the lower airflow and cooling uniformity.

[0047] To achieve uniform airflow distribution at the bottom, ensure consistent airflow logic between the upper and lower air guide structures, and simultaneously achieve centralized collection and diversion of quenching wastewater, see [reference needed]. Figure 12 As shown, the lower air guide mechanism 52 includes a second conveying frame 521, which is fixedly installed in the middle of the second mounting frame 51. The lower air inlet of the second conveying frame 521 is connected to the output port of the second fan 7. A second diverter 522 is provided in the middle of the inner cavity of the second conveying frame 521. The structure and function of the second diverter 522 are the same as those of the first diverter 422. Guide frames 523 are provided on both sides of the outer surface of the second conveying frame 521.

[0048] Specifically, after the high-pressure airflow output by fan 2 7 enters the inner cavity of conveying frame 2 521, it completes multi-stage diversion and uniform distribution through diverter 2 522 in the middle of the inner cavity. Diverter 2 522 replicates the multi-stage arc-shaped diversion structure and diversion principle of diverter 1 422, which can evenly disperse the concentrated airflow to the entire area of ​​conveying frame 2 521. The uniform airflow after diversion is finally discharged through the upper air supply mechanism 53 and acts on the lower part of the aluminum profile.

[0049] Furthermore, the guide frames 523 assembled on both sides of the conveyor frame 521 are wastewater collection and receiving structures, which can specifically receive and collect the condensate and quenching wastewater that is released and dripped during the operation of the air conveying mechanism 53, so as to realize the centralized collection of wastewater and avoid the wastewater from scattering and polluting the equipment and working environment.

[0050] To adapt to the roller arrangement structure of roller conveyor component 6 and achieve precise gap air delivery, airflow recycling, and wastewater stratification, see [reference needed]. Figures 13 to 15 As shown, the air conveying mechanism 53 includes a second mounting plate 531, which is fixedly installed on the upper part of the second conveying frame 521. A plurality of air conveying components 532 are provided in the middle of the second mounting plate 531, and air guides 533 are provided at the lower part of each of the plurality of air conveying components 532. The plurality of air conveying components 532 are arranged between the plurality of conveying rollers in the roller conveying component 6.

[0051] Specifically, the uniform airflow after being diverted in the inner cavity of the second conveyor frame 521 is directed into the interior of multiple air conveyor components 532. The airflow entering the air conveyor component 532 is divided into two paths. The first path of airflow blows directly upward, passes through the gap between the rollers, and acts directly on the lower surface of the aluminum profile to achieve direct cooling. The second path of airflow is directed into the inner cavity of the lower air guide component 533. After being guided by the air guide component 533, it flows back to the lower air inlet of the second conveyor frame 521 for use as supplementary air circulation.

[0052] Furthermore, during the flow of air through the air guide 533, the high-speed airflow will create a negative pressure at the inlet of the air guide 533, drawing in the air carrying water mist from the outside into the inner cavity of the air guide 533 and the air conveyor 532. During the flow of the water mist air, some water mist particles will adhere to the inner wall of the air conveyor 532 and the air guide 533, and gather to form liquid water droplets. The water droplets are guided along the inner wall to the inside of the guide frame 523 for collection. The remaining water mist particles are blown out from the air conveyor 532 with the circulating airflow and continue to participate in the quenching and cooling operation of the aluminum profile.

[0053] To achieve zoned air curtain delivery and optimize airflow guidance paths to ensure stable circulating airflow, see [reference needed]. Figure 16 and Figure 17 As shown, the air conveying component 532 includes a collection hopper 5321. Two air knives 5322 are provided on both sides of the outer surface of the collection hopper 5321. The lower part of the two air knives 5322 is fixedly connected to the inner wall of the mounting hole on the mounting plate 531. The inner cavity of the two air knives 5322 communicates with the inner cavity of the conveying frame 521. An arc frame 5323 is provided between the collection hopper 5321 and the two air knives 5322. The two arc frames 5323 are used to connect the inner cavities of the collection hopper 5321 and the two air knives 5322.

[0054] Specifically, the high-pressure airflow inside the second conveying frame 521 preferentially flows into the inner cavities of the two side air knives 5322, and is sprayed upward by the air knives 5322 to form a lower air curtain, which acts on the lower part of the aluminum profile. At the same time, part of the airflow is guided by the arc frame 5323 and flows into the inner cavity of the collection hopper 5321. The arc frame 5323 adopts a semi-circular flow channel structure, which can vertically guide the airflow, so that the airflow entering the collection hopper 5321 is blown into the inner cavity of the guide element 533 in a stable vertical downward state.

[0055] Furthermore, the vertical downward airflow within the collection hopper 5321 continuously creates a negative pressure adsorption effect, which can stably draw in external air carrying water mist into the inner cavity, continuously replenishing the water mist medium required for quenching. At the same time, the flow guiding and limiting effect of the arc-shaped frame 5323 prevents airflow turbulence and random movement, ensuring the stability of the lower airflow circulation and water mist replenishment.

[0056] To achieve a secondary uniform distribution of the return airflow, and to optimize the wastewater guide structure to prevent the supply airflow from leaking out with the wastewater, thus ensuring the equipment's airtight ventilation effect, see [reference needed]. Figures 16 to 18 As shown, the air guide 533 includes a W-shaped frame 5331. The middle part of the W-shaped frame 5331 is connected to the lower part of the collection hopper 5321, and the inner cavity of the W-shaped frame 5331 is connected to the inner cavity of the collection hopper 5321. The air outlets on both sides of the W-shaped frame 5331 point to the lower part of the two air knives 5322. The lower two sides of the W-shaped frame 5331 are provided with guide pipes 5332. Both ends of the two guide pipes 5332 extend into the interior of the guide frame 523. Multiple semi-circular plates 5333 are provided on both sides of the inner cavity of the two guide pipes 5332. The multiple semi-circular plates 5333 located on the same guide pipe 5332 are distributed vertically at intervals.

[0057] Specifically, the airflow collected by the collection bucket 5321 and flowing into the inner cavity of the W-shaped frame 5331 is diverted to both sides by the diversion structure of the W-shaped frame 5331 and directed into the lower air inlets of the two air blades 5322, continuously supplying airflow to the air blades 5322, realizing closed-loop recycling of airflow and improving airflow utilization.

[0058] Furthermore, the water droplets formed by the condensation of the externally drawn-in water mist in the W-shaped frame 5331 and the collection hopper 5321 can flow smoothly into the lower guide pipe 5332 and finally converge into the guide frame 523 through the guide pipe 5332, completing the centralized recycling of wastewater. At the same time, the multiple semi-circular plates 5333 distributed vertically in the inner cavity of the guide pipe 5332 can form a labyrinth-like flow-blocking structure, effectively preventing the high-pressure airflow inside the W-shaped frame 5331 and the collection hopper 5321 from leaking out of the guide pipe 5332. This ensures smooth wastewater flow while maintaining stable internal air pressure, thus ensuring the effectiveness of the quenching operation.

[0059] Furthermore, the main airflow of the second air knife 5322 is directly supplied by the second conveying frame, and the circulating airflow of the W-shaped frame 5331 is incorporated from the bottom as makeup air to increase the airflow.

[0060] Furthermore, some of the water mist air drawn in from the outside condenses into water droplets inside the W-shaped frame 5331 and the collection hopper 5321. This water flows into the inner cavity of the guide pipe 5332, while the other part of the water mist air flows along the channel inside the W-shaped frame 5331 and is then guided to the two air knives 5322. After that, it is blown from the two air knives 5322 onto the aluminum profile to perform quenching treatment on the aluminum profile. This part is to utilize the dissipated water mist and improve the utilization rate of the water mist.

[0061] Furthermore, the condensed water will continuously accumulate in the inner cavity of the guide tube 5332. When the water level in the guide tube 5332 is higher than the lower semicircular plate 5333, the water above the lower semicircular plate 5333 can flow out from the inside of the guide tube 5332. At the same time, when the water level in the guide tube 5332 is higher than or equal to the height of the lower semicircular plate 5333, the water surface will contact the lower end of the upper semicircular plate 5333. At this time, the gas cannot flow from the inside of the guide tube 5332 to the outside, thus achieving a sealing effect to a certain extent.
