Description

Technical Field

[0001] The invention belongs to the field of aluminum material processing, in particular to a cooling device for an aluminum alloy plate extrusion production line. Background Art

[0002] In the process of preparing aluminum alloy products, the general production process will have an extrusion step. After the raw materials are extruded into shape, the temperature of the formed aluminum alloy plate is extremely high and must be quickly cooled and shaped. Therefore, multiple sets of clamping mechanisms are used to clamp the profile and then use fans, sprays or atomizing devices to implement external cooling to facilitate subsequent product production.

[0003] A patent document with announcement number CN213728615U discloses a cooling device for aluminum product processing, including a conveyor mesh chain and a support plate. Multiple groups of chains are installed on the periphery of the conveyor mesh chain, and positioning plates are installed on the outside of the chain. The aluminum plate to be cooled is placed between the two positioning plates and in contact with the upper surface of the conveyor mesh chain.

[0004] Although traditional cooling methods can achieve simultaneous temperature reduction during the transmission process, they generally adopt horizontal transmission. Only one side of the profile is cooled and needs to be turned over later, which lengthens the transmission chain and increases the equipment footprint. At the same time, the transmission structure has large gaps and the cooling medium is prone to leakage. If vertical transmission is used instead, an additional clamping mechanism is required. The distance between the clamping mechanism and the aluminum alloy plate needs to be frequently adjusted when it initially clamps the aluminum alloy plate, which not only affects the transmission efficiency, but also increases the long-term wear rate of the equipment.

[0005] To this end, the present invention provides a cooling device for an aluminum alloy plate extrusion production line to solve the problems in the above-mentioned background technology. Summary of the Invention

[0007] Preferably, a mounting bar is fixedly installed above the conveyor, and the mounting bar is located within the distance above the two transmission components. A plurality of rotating shafts are movably installed inside the top of the mounting bar, and the top horizontal plane of the rotating shaft is higher than the top horizontal plane of the mounting bar.

[0008] Preferably, the conveying assembly includes two frames fixedly mounted on the inner wall of the inclined mounting groove, a conveyor belt is installed around the two frames, and rotating structures are provided inside both ends of the two frames for driving the conveyor belt.

[0009] Preferably, the conveyor belt type is a metal chain plate or chain type hard structure.

[0010] Preferably, the clamping plate includes a connecting strip fixedly mounted on the outside of the conveyor belt and an L-shaped plate fixedly mounted on one side of the connecting strip, a vertical plate fixedly mounted on one side of the L-shaped plate, and the vertical plate is vertically arranged.

[0011] Preferably, an oblique groove and a cooling groove are provided inside the vertical plate, a plurality of support bars are fixedly installed inside the cooling groove, and the interiors of the oblique groove and the cooling groove are used to store cold air.

[0012] Preferably, an L-shaped air duct is fixedly installed on the side of the isolation plate away from the extrusion production device, the upper end of the L-shaped air duct is connected to the interior of the cooling box, and opposite strip air outlets are opened below the isolation plate, and the lower end of the L-shaped air duct is used to supply air to the opposite strip air outlets.

[0013] Preferably, the opposing strip air vents are arranged toward the vertical plate, and the opposing strip air vents have an oblique air outlet, so as to blow away the gas in the nearest oblique slot and the cooling slot.

[0014] Preferably, a component strip is fixedly installed on the outer side of the isolation plate, and the upper part of the component strip is connected to the lower end of the L-shaped air duct. The component strip is provided with an air outlet groove on the side facing the opposite strip air outlet. The air outlet groove is connected to the opposite strip air outlet, and the oblique air outlet angles of the two are consistent.

[0015] Preferably, an air knife is fixedly installed inside the air outlet slot, and a brush is fixedly installed on one side of the component strip.

[0016] The beneficial effects of the present invention are as follows: 1. The cooling device for an aluminum alloy plate extrusion production line described in the present invention is that when a vertical aluminum alloy plate approaches and is conveyed to the top of a conveyor, the distance between the two clamping plates at the closest distance is greater than the thickness of the aluminum alloy plate. As the aluminum alloy plate continues to move toward the conveyor, the distance between the two clamping plates of the same group of transmissions gradually becomes smaller until the aluminum alloy plate is clamped. As the transmission progresses, more two clamping plates with smaller distances are clamped on both sides of the aluminum alloy plate to stabilize it and maintain the vertical state of the aluminum alloy plate. When the vertical aluminum alloy plate enters the interior of the cooling box through the isolation plate, the cold air inside the cooling box after the air cooling device has worked can quickly cool the vertical aluminum alloy plate. The large-area contact between the cooling medium and the aluminum alloy plate can quickly improve the cooling efficiency.

[0017] 2. The cooling device for an aluminum alloy plate extrusion production line described in the present invention is achieved by modifying a vertical plate of a certain thickness and providing an oblique groove and a cooling groove so that cold air can be stored inside the cooling box. The arrangement of multiple support bars is used to strengthen the structural strength of the vertical plate. As the vertical plate is transmitted, the cold air inside the oblique groove and the cooling groove can be gradually replaced, that is, a cold air cavity is provided inside the vertical plate, so that the clamping contact surface between the vertical plate and the aluminum alloy plate can also be quickly cooled.

[0018] 3. The cooling device for an aluminum alloy plate extrusion production line described in the present invention blows out a vertical airflow toward the oblique groove through a wind knife, so that the blown airflow replaces the original cold air in the oblique groove and the cooling groove. Because the original airflow in the oblique groove and the cooling groove is the airflow in a relatively central position inside the cooling box, the temperature is relatively low, while the airflow sucked in by the L-shaped air duct is the airflow that exchanges heat with the outside world through the isolation plate, and the temperature is relatively high. This airflow replacement method can significantly maintain the low temperature inside the cooling box. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example 1: Figures 1-4 As shown, a cooling device for an aluminum alloy plate extrusion production line according to an embodiment of the present invention includes an extrusion production device 1 and a conveyor 2 installed on one side of the extrusion production device 1. The extrusion production device 1 is used to extrude raw materials to produce aluminum alloy plates. A cooling box 3 is installed on the conveyor 2, and an air cooling device 4 is installed above the cooling box 3. Two inclined mounting grooves 23 are provided inside the conveyor 2, and a conveying assembly 21 is fixedly installed inside the two inclined mounting grooves 23. A plurality of clamping plates 22 are fixedly installed on the conveying structure of the conveying assembly 21. The top ends of the plurality of clamping plates 22 are vertically arranged. The two conveying assemblies 21 are in an inverted V-shaped state, and the distance between the two conveying assemblies 21 below is greater than the distance between the two conveying assemblies above. Isolation plates 31 are installed on both sides of the cooling box 3 , and the plurality of clamping plates 22 and the clamped aluminum alloy plates enter and exit the cooling box 3 through the isolation plates 31 .

[0024] Specifically, the aluminum alloy plate is extruded and formed by the extrusion production device 1 and then vertically conveyed to one side of the conveyor 2. At this time, the conveying component 21 is driven, and the multiple clamping plates 22 on the outer side of the conveying component 21 are driven along with the driving of the conveying component 21. Because the two conveying components 21 are in an inverted V-shaped state, when the multiple clamping plates 22 corresponding to each other are set on the two conveying components 21, the distance between the multiple clamping plates 22 corresponding to each other in the middle above the conveyor 2 is fixed, and the distance between the multiple clamping plates 22 corresponding to each other at both ends above the conveyor 2 is larger, and the thickness of the aluminum alloy plate is smaller than this larger distance, and the two pairs of clamping plates 22 are fixed. The clamping plates 22 with fixed spacing can clamp and convey the aluminum alloy plate. When the corresponding clamping plates 22 are at the inner bottom of the conveyor 2 for transmission, the spacing between the multiple clamping plates 22 at the inner bottom of the conveyor 2 is also relatively large. The multiple clamping plates 22 can be transmitted following the transmission component 21. Therefore, the change in spacing is gradual and does not require external structure to adjust. When the vertical aluminum alloy plate approaches and is conveyed to the top of the conveyor 2, the spacing between the two clamping plates 22 at the closest distance is greater than the thickness of the aluminum alloy plate. As the aluminum alloy plate continues to move toward the conveyor 2, the spacing between the two clamping plates 22 of the same group of transmissions gradually becomes smaller until the aluminum alloy plate is Alloy plate clamping, with the transmission, two clamping plates 22 with smaller spacing are clamped on both sides of the aluminum alloy plate to stabilize it and keep the aluminum alloy plate in a vertical state. When the vertical aluminum alloy plate enters the cooling box 3 through the isolation plate 31, the cold air inside the cooling box 3 after the air cooling device 4 works can quickly cool the vertical aluminum alloy plate. The large area contact between the cooling medium and the aluminum alloy plate can quickly improve the cooling efficiency. Compared with the traditional flat conveying cooling, there is no need to cool one side and then cool the other side, which can reduce the floor space of the device. In addition, the wrapping of the cooling box 3 in this device is relatively strong. Compared with the large gap of the traditional flat conveying structure, the leakage of cold air can be reduced to a greater extent, thereby reducing costs. The inverted V-shaped setting of the two conveying components 21 in this device can gradually adjust the spacing between multiple corresponding clamping plates 22 without external force adjustment. When the aluminum alloy plate is just conveyed to the conveyor 2, the spacing between the two clamping plates 22 is greater than the thickness of the aluminum alloy plate. As the aluminum alloy plate is conveyed, it is gradually clamped. Compared with traditional technology, less structure is required to adjust the spacing between the two clamping plates 22, and the aluminum alloy plate will not be squeezed between the two clamping plates 22 for clamping, thereby reducing damage to the aluminum alloy plate.

[0025] like Figure 3-Figure 6 As shown, a mounting bar 24 is fixedly installed above the conveyor 2, and the mounting bar 24 is located in the distance above the two transmission components 21. A plurality of rotating shafts 241 are movably installed inside the top of the mounting bar 24, and the top horizontal plane of the rotating shaft 241 is higher than the top horizontal plane of the mounting bar 24.

[0026] The conveying assembly 21 includes two frames 211 fixedly mounted on the inner wall of the inclined mounting groove 23 , a conveyor belt 212 is installed around the two frames 211 , and rotating structures are provided inside both ends of the two frames 211 for driving the conveyor belt 212 .

[0027] The conveyor belt 212 is preferably a metal chain plate or chain type hard structure.

[0028] The clamping plate 22 includes a connecting strip 223 fixedly mounted on the outside of the conveyor belt 212 and an L-shaped plate 222 fixedly mounted on one side of the connecting strip 223 . A vertical plate 221 is fixedly mounted on one side of the L-shaped plate 222 , and the vertical plate 221 is vertically arranged.

[0029] Specifically, when the aluminum alloy plate is initially transported to the conveyor 2, its bottom contacts the multiple rotating shafts 241 on the mounting bar 24. As two or more clamping plates 22 clamp the aluminum alloy plate for transportation, the bottom of the aluminum alloy plate contacts different multiple rotating shafts 241. The rolling multiple rotating shafts 241 reduce the friction of the aluminum alloy plate during transportation, thereby improving the cooling efficiency. The two conveying components 21 are each fixedly installed inside the corresponding inclined mounting groove 23, and the rotating structure inside the frame 211 is driven by the cooperation of the external motor output shaft and the universal shaft, thereby allowing the conveyor belt 212 to transmit. The length of the connecting bar 223 is relatively small and can be fixedly connected to the outside of the metal chain plate or chain-like transmission structure. The presence of the L-shaped plate 222 allows the vertical plate 221 to extend to the outside of the conveying component 21, so that the distance between the two corresponding clamping plates 22 at the same position is smaller than the distance between the two conveying components 21, that is, the two clamping plates 22 at the same position clamp the aluminum alloy plate.

[0030] like Figure 7 As shown, the vertical plate 221 is provided with an oblique groove 2211 and a cooling groove 2212 . A plurality of support bars 2213 are fixedly installed inside the cooling groove 2212 . The oblique groove 2211 and the cooling groove 2212 are used to store cold air.

[0031] Specifically, the vertical plate 221 used to clamp the aluminum alloy plate needs to have a certain thickness to prevent the vertical plate 221 that is too thin from being affected by the weight of the aluminum alloy plate during clamping and causing damage. However, the vertical plate 221 with a certain thickness will reduce the cooling of the aluminum alloy plate. Therefore, in this device, the vertical plate 221 with a certain thickness is modified, and the oblique groove 2211 and the cooling groove 2212 are provided so that cold air can be stored inside the cooling box 3. The provision of multiple support bars 2213 is used to strengthen the structural strength of the vertical plate 221, and as the vertical plate 221 is transmitted, the cold air inside the oblique groove 2211 and the cooling groove 2212 can be gradually replaced, that is, a cold air cavity is provided inside the vertical plate 221, so that the clamping contact surface between the vertical plate 221 and the aluminum alloy plate can also be quickly cooled.

[0032] Example 2: Figure 7-Figure 8 As shown, compared with Example 1, another embodiment of the present invention is: an L-shaped air duct 312 is fixedly installed on the side of the isolation plate 31 away from the extrusion production device 1, the upper end of the L-shaped air duct 312 is connected to the interior of the cooling box 3, and a facing strip air outlet 311 is opened below the isolation plate 31, and the lower end of the L-shaped air duct 312 is used to supply air to the facing strip air outlet 311.

[0033] The opposite strip air vents 311 are arranged toward the vertical plate 221 , and the opposite strip air vents 311 are configured to discharge air in an oblique direction, so as to blow away the gas in the nearest oblique slot 2211 and the cooling slot 2212 .

[0034] A component strip 32 is fixedly installed on the outer side of the isolation plate 31. The upper part of the component strip 32 is connected to the lower end of the L-shaped air duct 312. The component strip 32 is provided with an air outlet groove 321 on the side facing the opposite strip air outlet 311. The air outlet groove 321 is connected to the opposite strip air outlet 311, and the angles of the oblique air outlet of the two are consistent.

[0035] An air knife 322 is fixedly installed inside the air outlet slot 321 , and a brush 323 is fixedly installed on one side of the component bar 32 .

[0036] Specifically, when multiple vertical plates 221 corresponding to each other in pairs are clamping the aluminum alloy plates for transportation and are about to leave the cooling box 3, the inclined angle of the oblique groove 2211 is consistent with the outlet angle of the opposite strip air outlet 311, the outlet strip groove 321 and the wind knife 322, and the electrically driven wind knife 322 works, and the airflow inside the cooling box 3 on one side of the isolation plate 31 is sucked through the L-shaped air duct 312, and the wind knife 322 blows out a vertical airflow toward the oblique groove 2211, so that the blown airflow replaces the original cold air in the oblique groove 2211 and the cooling groove 2212. Because the original airflow in the oblique groove 2211 and the cooling groove 2212 is the airflow in the relatively central position of the cooling box 3, the temperature is lower, and the airflow sucked in by the L-shaped air duct 312 is the airflow that has been exchanging heat with the outside world across the isolation plate 31, and the temperature is higher. This airflow replacement method can significantly maintain To maintain the low temperature inside the cooling box 3, if the wind knife 322 is not set, when the vertical plate 221 moves toward the outside of the cooling box 3, it will not only drive the cold air with lower temperature in the oblique groove 2211 and the cooling groove 2212, but also the convection air leaked out of the cooling box 3. The setting of the wind knife 322 brings this part of the leaked convection air back to the inside of the cooling box 3, that is, the vertical plate 221 originally wanted to take away the cold air with lower temperature inside it and the leaked cold air transmitted by the vertical plate 221, but in this device, due to the air flow replacement of the wind knife 322, the vertical plate 221 can ultimately only drive the higher temperature cold air replaced inside it, which can effectively improve the cooling efficiency and reduce the air supply cost. When the vertical plate 221 passes through the opposite strip air outlet 311, it will contact the brush 323. The setting of the brush 323 can block the cold air blown back and prevent the hot air from the outside from being sucked in.

[0037] Working principle: After the aluminum alloy plate is extruded and formed by the extrusion production device 1, it is vertically conveyed to one side of the conveyor 2. At this time, the conveying component 21 is driven, and the multiple clamping plates 22 on the outside of the conveying component 21 are driven along with the driving of the conveying component 21. Because the two conveying components 21 are in an inverted V-shaped state, when the multiple clamping plates 22 corresponding to each other are set on the two conveying components 21, the distance between the multiple clamping plates 22 corresponding to each other in the middle of the upper part of the conveyor 2 is fixed, and the distance between the multiple clamping plates 22 corresponding to each other at both ends of the upper part of the conveyor 2 is larger, and the thickness of the aluminum alloy plate is smaller than this larger distance. The two corresponding and fixed-distance clamping plates 22 can clamp and convey the aluminum alloy plate. When the two corresponding clamping plates 2 When the vertical aluminum alloy plate approaches and is transported to the top of the conveyor 2, the distance between the two clamping plates 22 at the bottom of the conveyor 2 is also relatively large. The multiple clamping plates 22 can be transported along with the transmission component 21, so the change in distance is gradual and does not require any external structure to adjust. When the vertical aluminum alloy plate approaches and is transported to the top of the conveyor 2, the distance between the two clamping plates 22 at the closest distance is greater than the thickness of the aluminum alloy plate. As the aluminum alloy plate continues to move toward the conveyor 2, the distance between the two clamping plates 22 of the same group of transmission gradually decreases until the aluminum alloy plate is clamped. As the transmission progresses, more two clamping plates 22 with smaller distances are clamped on both sides of the aluminum alloy plate to stabilize it and keep it in a vertical state. When the vertical aluminum alloy plate passes through the isolation plate 31, the distance between the two clamping plates 22 at the closest distance is greater than the thickness of the aluminum alloy plate. As the aluminum alloy plate continues to move toward the conveyor 2, the distance between the two clamping plates 22 of the same group of transmission gradually decreases until the aluminum alloy plate is clamped. As the transmission progresses, more two clamping plates 22 with smaller distances are clamped on both sides of the aluminum alloy plate to stabilize it and keep it in a vertical state. After entering the cooling box 3, the cold air inside the cooling box 3 after the air cooling device 4 works can quickly cool the vertical aluminum alloy plate. The large area contact between the cooling medium and the aluminum alloy plate can quickly improve the cooling efficiency. Compared with the traditional flat conveying cooling, there is no need to cool one side and then cool the other side, which can reduce the floor space of the device. In addition, the wrapping of the cooling box 3 in this device is relatively strong. Compared with the large gap of the traditional flat conveying structure, it can reduce the leakage of cold air to a greater extent, thereby reducing the cost. In addition, the inverted V-shaped setting of the two conveying components 21 in this device can gradually adjust the distance between the multiple corresponding clamping plates 22 without external force adjustment. When the aluminum alloy plate is just conveyed to the conveyor 2, the two clamping plates 22 are The distance between the plates 22 is greater than the thickness of the aluminum alloy plate. As the aluminum alloy plate is transported, the aluminum alloy plate is gradually clamped. Compared with the traditional technology, the structure for adjusting the distance between the two clamping plates 22 can be reduced, and the aluminum alloy plate will not be squeezed between the two clamping plates 22 for clamping, thereby reducing damage to the aluminum alloy plate. When multiple vertical plates 221 corresponding to each other are clamping the aluminum alloy plate and are about to leave the cooling box 3, the inclined angle of the oblique groove 2211 is consistent with the outlet angle of the opposite strip air outlet 311, the outlet strip groove 321 and the wind knife 322. The electric drive wind knife 322 works and sucks the airflow on one side of the isolation plate 31 inside the cooling box 3 through the L-shaped air duct 312. The wind knife 322 blows out a vertical airflow toward the oblique groove 2211.The blown airflow replaces the original cold air in the oblique slot 2211 and the cooling slot 2212, because the original airflow in the oblique slot 2211 and the cooling slot 2212 is the airflow in the relatively central position of the cooling box 3, and the temperature is relatively low, while the airflow sucked in by the L-shaped air duct 312 is the airflow that has been exchanging heat with the outside through the isolation plate 31, and the temperature is relatively high. This airflow replacement method can significantly maintain the low temperature inside the cooling box 3. If the wind knife 322 is not provided, when the vertical plate 221 moves toward the outside of the cooling box 3, it will not only drive the cold air with lower temperature in the oblique slot 2211 and the cooling slot 2212, but also additionally superimpose the cold air in the cooling box 3. The convection air leaking outward is carried back to the interior of the cooling box 3 by the wind knife 322. That is, the vertical plate 221 is originally intended to carry away the cool air with a lower temperature inside and the leaked cool air transmitted by the vertical plate 221. However, in this device, due to the airflow replacement provided by the wind knife 322, the vertical plate 221 can ultimately only carry the replaced cool air with a higher temperature inside, which can effectively improve the cooling efficiency and reduce the air supply cost. When the vertical plate 221 passes through the opposite strip air outlet 311, it will come into contact with the brush 323. The brush 323 is provided to block the cool air blown back and prevent the hot air from the outside from being sucked in.
