Description

Technical Field

[0001] This invention relates to the field of aluminum ingot forming cooling technology, specifically to a segmented gradient cooling device for aluminum ingot forming. Background Technology

[0002] Aluminum ingots, as the basic raw material for aluminum processing and casting, are widely used in industrial production processes such as profile extrusion, plate rolling, forging, and precision casting. They are an indispensable intermediate forming product in the aluminum industry chain. The cooling process of aluminum ingots after high-temperature casting directly determines their internal density, grain uniformity, overall mechanical properties, appearance flatness, and dimensional accuracy. At the same time, it also significantly affects the magnitude and distribution of residual stress inside the aluminum ingot. These indicators not only relate to the factory qualification rate of the aluminum ingot itself, but also directly affect the forming stability, processing accuracy, and finished product yield of subsequent deep processing processes such as rolling, extrusion, stretching, and forging. They play a decisive role in the strength, toughness, corrosion resistance, and service life of the final aluminum products.

[0003] Existing aluminum ingot forming cooling devices mostly use fixed nozzles for direct spraying, resulting in inconsistent cooling rates on different parts of the aluminum ingot surface. This can easily lead to problems such as localized sudden cooling, overheating in the center, and undercooling at the edges and corners. Consequently, large residual stress is generated inside the aluminum ingot, which can easily cause defects such as warping, cracking, porosity, and coarse grains. This severely reduces the forming quality and stability of the aluminum ingot. In addition, in traditional production lines, the aluminum ingot is placed on a conveyor wheel for cooling throughout the entire process. The conveyor components are in continuous contact with the bottom of the aluminum ingot, causing uneven heat conduction and delayed cooling at the bottom.

[0004] Based on this, the present invention designs a segmented gradient cooling device for aluminum ingot forming to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a segmented gradient cooling device for aluminum ingot forming, in order to solve the problems mentioned in the background art. Existing aluminum ingot forming cooling devices mostly use fixed nozzles for direct spraying, resulting in inconsistent cooling rates on different parts of the aluminum ingot surface. This can easily lead to problems such as localized sudden cooling, overheating in the center, and undercooling at the edges and corners, causing large residual stress inside the aluminum ingot. Subsequently, defects such as warping, cracking, porosity, and coarse grains are likely to occur, severely reducing the forming quality and stability of the aluminum ingot. At the same time, in traditional production lines, the aluminum ingot is placed on the conveyor roller for cooling throughout the entire process. The conveyor components are in continuous contact with the bottom of the aluminum ingot, causing uneven heat conduction and delayed cooling at the bottom.

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

[0007] A segmented gradient cooling device for aluminum ingot forming includes a conveying mechanism. The conveying mechanism includes a mounting base. Six conveying wheels are rotatably mounted on the top of the inner wall of the mounting base via bearings, with two conveying wheels forming a group. The interval between each group of conveying wheels is the same. Three sets of intermittent lifting mechanisms are respectively provided inside the mounting base at positions corresponding to each group of conveying wheels. Lifting and rotating mechanisms are respectively provided at positions corresponding to the three sets of intermittent lifting mechanisms in the conveying mechanism. The aluminum ingot body is placed at equal intervals on the top of the conveying mechanism. Segmented gradient cooling mechanisms are provided at positions corresponding to the three sets of intermittent lifting mechanisms and lifting and rotating mechanisms on the top of the conveying mechanism.

[0008] As a further embodiment of the present invention, a first conveyor wheel is rotatably mounted on both sides of each set of second conveyor wheels via bearings on the top of the inner wall of the mounting base. A linkage turntable is fixedly mounted at both ends of the first and second conveyor wheels, penetrating the mounting base. A dual-output shaft motor is fixedly mounted on one side of the bottom of the mounting base. A push turntable is fixedly mounted on each of the output ends of the dual-output shaft motor.

The edges of the intermittent turntable one and the multiple push turntables two on the same side of the mounting base are rotatably connected with a linkage bar two through a protrusion. The linkage shaft is fixedly installed with a drive bevel gear at the center position of the inner surface of the mounting base.

[0011] As a further embodiment of the present invention, the lifting and rotating mechanism includes two limiting slide rods. The two ends of the limiting slide rods are fixedly connected to the inside of the mounting base, and the two limiting slide rods are symmetrically fixedly connected to both sides of the push turntable. The two ends of the two limiting slide rods are respectively slidably mounted with concave slide frames. A push slide groove is provided through the center of the bottom of the concave slide frame, and the push slide groove is slidably connected to the two ends of the center of the rotating crankshaft. The two ends of the top of the two concave slide frames are fixedly connected with lifting top plates. A rotating column is rotatably mounted at the center of the bottom of the lifting top plate through a bearing. A rotating disk is fixedly mounted through the top of the rotating column through the lifting top plate, and the rotating disk rotates close to the lifting top plate.

[0012] As a further embodiment of the present invention, two mounting strips are fixedly installed on the inner wall of the mounting base between each set of two transmission wheels. A rotating sleeve is rotatably installed at the center position between the two mounting strips via a bearing. The bottom end of the rotating column is slidably connected to the inside of the rotating sleeve. Four limiting protrusions are fixedly installed at equal angles at the edge of the bottom end of the rotating column. Four limiting grooves are provided at equal angles on the surface of the rotating sleeve between the two mounting strips. The limiting protrusions are slidably connected to the inside of the limiting grooves. A driven bevel gear is fixedly connected to the bottom end of the rotating sleeve through the mounting strips.

[0014] As a further embodiment of the present invention, a linkage rotating plate is rotatably mounted at the center of the side wall on one side of the outer surface of the cooling cover via a bearing. A connecting strip is rotatably mounted through one end of the linkage rotating plate and the drive rotating plate. A rotating curved plate frame is fixedly mounted inside the cooling cover through one end of the linkage rotating plate. Mounting support plates are symmetrically fixedly mounted on both sides of the rotating curved plate frame on the inner side of the cooling cover.

A rectangular mounting frame is fixedly mounted on one side of the rotating spray strip, and a swing column is rotatably mounted inside the rectangular mounting frame via a bearing. The end of the swing column located outside the rectangular mounting frame is rotatably connected to the rotating curved plate frame via a bearing.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention, through the configuration of a push turntable 1, an intermittent turntable 1, a linkage bar 1, a linkage bar 2, a lifting top plate, and a rotating disk, allows the aluminum ingot body to be placed at one end of the top of the conveying mechanism. The dual-output shaft motor then drives the push turntable 1 on both sides to rotate. The pushing protrusions on the push turntable 1 engage with the slots of the intermittent turntable 1, causing it to rotate intermittently. Under the synchronous linkage of the linkage bar 1, the conveying wheel 1 and the conveying wheel 2 achieve intermittent operation at the same speed and in the same direction, smoothly and accurately conveying the aluminum ingot body to the work position directly below the cooling hood, completing the pre-cooling positioning. Under the linkage of the linkage bar 2, the push turntable 2 rotates synchronously with the conveying mechanism, thereby driving the intermittent turntable 2 to rotate intermittently. The intermittent turntable 2 drives the connecting turntable and the rotating crankshaft to perform circular motion, pushing the concave slide 1 to slide up and down along the mounting slide, thus... The fixed top block assists in positioning, ensuring that the cooling shroud completely covers the surface of the aluminum ingot body, forming a closed cooling space. Simultaneously, the rotating crankshaft pushes the concave slide carriage two upward along the limiting slide rod through the push slide groove, causing the lifting top plate to move upward until the rotating disk is tightly attached to the bottom of the aluminum ingot body, smoothly lifting the aluminum ingot body and completely separating it from the first and second conveyor wheels, avoiding interference with cooling by the conveying components. The push turntable two synchronously drives the linkage shaft and the drive bevel gear to rotate. The drive bevel gear meshes with the driven bevel gear, driving the rotating sleeve to rotate. The rotating sleeve drives the rotating column and the rotating disk to rotate synchronously through the sliding engagement of the limiting slide groove and the limiting protrusion, thereby causing the aluminum ingot body to rotate at a uniform speed within the cooling shroud. Combined with the rotating spray strips of the segmented gradient cooling mechanism, uniform cooling of the aluminum ingot body without dead angles is achieved.

[0017] 2. This invention, by setting up a drive motor, drive rotating plate, linkage rotating plate, connecting strip, swing column, and rotating curved plate frame, ensures that the cooling cover completely covers the aluminum ingot body and forms a closed cooling space. After the drive motor is started, the output end of the drive motor drives the drive rotating plate to rotate. Under the linkage action of the connecting column, the connecting rotating shaft and the drive rotating plates at both ends rotate synchronously, realizing the unified transmission of power for multiple cooling stations. The drive rotating plate pushes and pulls the linkage rotating plate through the connecting strip to make reciprocating swing, so that the linkage rotating plate drives the inner rotating curved plate frame to rotate synchronously. During the movement of the rotating curved plate frame, the drive swing column makes adaptive rotation within the rectangular mounting frame, converting the rotational motion into the up-and-down swing of the rotating spray strip. The rotating spray strip uses the mounting support plate as the support fulcrum and continuously swings up and down inside the cooling cover, spraying and cooling the surface of the aluminum ingot body evenly.

Detailed Implementation

[0033] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-12 The present invention provides a technical solution:

[0035] A segmented gradient cooling device for aluminum ingot forming includes a conveying mechanism 1. Aluminum ingot bodies 4 are placed equidistantly on the top of the conveying mechanism 1. The conveying mechanism 1 includes a mounting base 101. Six conveying wheels 103 are rotatably mounted on the top of the inner wall of the mounting base 101 via bearings. Two conveying wheels 103 form a group, and the interval between each group of conveying wheels 103 is the same. On both sides of each group of conveying wheels 103, conveying wheels 102 are rotatably mounted on the top of the inner wall of the mounting base 101 via bearings. Both ends of the conveying wheels 102 and 103 are fixedly mounted on a linkage turntable 104 through the mounting base 101.

[0036] A dual-output shaft motor 105 is fixedly installed on one side of the bottom of the mounting base 101. Push turntables 106 are fixedly installed on both sides of the dual-output shaft motor 105, passing through the mounting base 101. A rotating dial 108 is fixedly installed on the side of the push turntable 106 near the mounting base 101. A pushing protrusion 107 is fixedly installed on the edge of the push turntable 106 near the rotating dial 108. The rotating dial 108 has a circular disc structure, and its outer surface near the pushing protrusion 107 is flat. A transmission wheel 11 is located at one end of the top of the mounting base 101. 02 Intermittent turntable 109 is fixedly installed at both ends through the mounting base 101. Multiple slots are opened at equal angles on the edge of the intermittent turntable 109. The slots are engaged with the push protrusion 107. The edge of the intermittent turntable 109 between two slots is provided with a groove. The groove is close to the outer circle of the rotating dial 108. The intermittent turntable 109 is close to the push turntable 106. The slot on the surface of the intermittent turntable 109 is engaged with the push protrusion 107. The intermittent turntable 109 and the linkage turntable 104 on the same side of the mounting base 101 are connected by a linkage bar 110 through the protrusion.

[0037] During operation, the dual-output shaft motor 105 is started, which drives the two push turntables 106 on both sides to rotate. The push protrusions 107 on the push turntable 106 cooperate with the slots of the intermittent turntable 109, driving the intermittent turntable 109 to rotate intermittently. The intermittent turntable 109 drives the linkage turntable 104 to move synchronously through the linkage bar 110, thereby enabling the conveyor wheel 102 and the conveyor wheel 2 103 to rotate intermittently in the same direction and rhythm, so as to smoothly and accurately transport the aluminum ingot body 4 to the cooling station under the cooling cover 501, ensuring the accurate positioning of the aluminum ingot body 4 and providing a stable foundation for the subsequent cooling process.

[0038] Inside the mounting base 101, at positions corresponding to each set of conveyor wheels 103, are three sets of intermittent lifting mechanisms 2. Each intermittent lifting mechanism 2 includes a mounting slide 201, and there are four mounting slides 201. The four mounting slides 201 are fixedly connected in pairs to the inner wall of the mounting base 101 on both sides of each set of conveyor wheels 103. The bottoms of the two mounting slides 201 on the same side of the inner wall of the mounting base 101 are slidably mounted with concave slides 202, and the tops of the concave slides 202 are fixedly connected to fixed top blocks 203 through the mounting slides 201. The bottoms of the inner wall of the mounting base 101 corresponding to each set of conveyor wheels 103 are symmetrically mounted with connecting turntables 204 via bearings. The bottoms of the inner wall of the mounting base 101 and the bottoms of the connecting turntables 204 are respectively fixedly mounted with concave mounting brackets 205. A rotating crankshaft 206 is rotatably mounted between two opposing concave mounting brackets 205 via bearings. The two ends of the rotating crankshaft 206 are fixedly connected to the edges of the connecting turntable 204. The ends of the two connecting turntables 204 that are far apart from each other pass through the mounting base 101 and are respectively fixedly mounted with intermittent turntables 207. Multiple slots are equally spaced along the edge of the intermittent turntables 207, which engage with the protrusions on the edge of the pushing turntables 209. A groove is provided on the edge of the intermittent turntables 207 between two slots, and the groove is in close contact with the outer surface of the pushing turntables 209. A linkage shaft 208 is rotatably mounted on the inner wall of the mounting base 101 between each set of transmission wheels 203 and the connecting turntable 204 via a bearing. Push turntables 209 are fixedly installed at both ends of the mounting base 101. The push turntables 209 are flat discs with protrusions on their outer edges that intermittently engage with the slots on the surface of the intermittent turntables 207. At the same time, the outer circular surface of the push turntables 209 fits into the grooves on the surface of the intermittent turntables 207, and the push turntables 209 engage with the intermittent turntables 207. The edges of the intermittent turntables 109 and multiple push turntables 209 on the same side of the mounting base 101 are rotatably connected by protrusions through which a linkage bar 211 is connected. The linkage shaft 208 is fixedly installed with a drive bevel gear 210 at the center of the inner surface of the mounting base 101.

[0039] During operation, the intermittent turntable 109 drives the push turntable 209 to rotate synchronously via the linkage 211. The push turntable 209 drives the intermittent turntable 207 to rotate intermittently. The intermittent turntable 207 drives the connecting turntable 204 and the rotating crankshaft 206 to perform circular motion. Since the rotating crankshaft 206 has an overall eccentric crankshaft structure, the left and right ends of the rotating crankshaft 206 are symmetrical eccentric crankshaft structures. The eccentric crankshafts at both ends of the rotating crankshaft 206 push the concave slide 1 202 to slide up and down along the mounting slide 201. The concave slide 1 202 drives the fixed top block 203 to complete the positioning and support, so that the cooling cover 501 can stably and completely cover the surface of the aluminum ingot body 4, forming a closed cooling space, preventing the cooling medium from leaking out, and ensuring a stable cooling environment.

[0040] Lifting and rotating mechanisms 3 are respectively provided at the positions corresponding to the conveying mechanism 1 and the three sets of intermittent lifting mechanisms 2. The lifting and rotating mechanism 3 includes two limiting slide rods 301. The two ends of the limiting slide rods 301 are fixedly connected to the inside of the mounting base 101, and the two limiting slide rods 301 are symmetrically fixedly connected to both sides of the push turntable 209. The two ends of the two limiting slide rods 301 are respectively slidably mounted with concave slide brackets 302. A push slide groove 303 is provided through the center of the bottom of the concave slide bracket 302, and the push slide groove 303 is slidably connected to the two ends of the center of the rotating crankshaft 206. The two ends of the top of the two concave slide brackets 302 are fixedly connected with lifting top plates 304. A rotating column 305 is rotatably mounted at the center of the bottom of the lifting top plate 304 through a bearing. The top of the rotating column 305 is fixedly mounted with a rotating disk 306 through the lifting top plate 304, and the rotating disk 306 rotates close to the lifting top plate 304.

[0041] Two mounting strips 307 are fixedly installed on the inner wall of the mounting base 101 between each set of conveyor wheels 103. A rotating sleeve 308 is rotatably installed at the center position between the two mounting strips 307 via a bearing. The bottom end of the rotating column 305 is slidably connected to the inside of the rotating sleeve 308. Four limiting protrusions 310 are fixedly installed at equal angles on the edge of the bottom end of the rotating column 305. Four limiting grooves 311 are provided at equal angles on the surface of the rotating sleeve 308 between the two mounting strips 307. The limiting protrusions 310 are slidably connected to the inside of the limiting grooves 311. A driven bevel gear 309 is fixedly connected to the bottom end of the rotating sleeve 308 through the mounting strips 307. The driven bevel gear 309 meshes with the driving bevel gear 210.

[0042] During operation, the center of the rotating crankshaft 206 is eccentrically positioned relative to the axis of rotation, and a push groove 303 passes through the bottom of the concave slide 302. The rotating crankshaft 206 pushes the concave slide 302 upward along the limiting slide rod 301 via the push groove 303. The concave slide 302 drives the lifting top plate 304 to move upward, so that the rotating disk 306 fits tightly against the bottom of the aluminum ingot body 4, smoothly lifting the aluminum ingot body 4 and completely separating it from the first conveyor wheel 102 and the conveyor wheel. 203 eliminates the interference of the transmission components on cooling, and at the same time pushes the turntable 209 to drive the linkage shaft 208 and the drive bevel gear 210 to rotate. The drive bevel gear 210 meshes with the driven bevel gear 309 to drive the rotating sleeve 308 to rotate. The rotating sleeve 308 drives the rotating column 305 and the rotating disk 306 to rotate synchronously through the sliding cooperation of the limiting slide groove 311 and the limiting protrusion 310, thereby driving the aluminum ingot body 4 to rotate at a uniform speed in the cooling cover 501.

[0043] A segmented gradient cooling mechanism 5 is provided at the top of the conveying mechanism 1, corresponding to the three sets of intermittent lifting mechanisms 2 and lifting rotation mechanisms 3. The segmented gradient cooling mechanism 5 includes a cooling cover 501, and there are three cooling covers 501. The three cooling covers 501 are respectively set on the top of each set of conveying wheels 103. A drive motor 502 is fixedly installed at the center of the top edge of one cooling cover 501. Mounting plates 503 are fixedly installed at the center of the top sides of the other two drive motors 502. A connecting shaft 504 is rotatably installed between the two opposing mounting plates 503 through a bearing. Drive rotating plates 505 are fixedly installed at the output end of the drive motor 502 and both ends of the connecting rotating shaft 504. A connecting column 506 is fixedly installed at one end between two adjacent drive rotating plates 505.

[0044] A linkage rotating plate 507 is rotatably mounted on the center of one side wall of the outer surface of the cooling cover 501 via a bearing. A connecting strip 508 is rotatably mounted through one end between the linkage rotating plate 507 and the drive rotating plate 505. One end of the linkage rotating plate 507 extends through the side wall of the cooling cover 501 and is fixedly mounted inside the cooling cover 501 to a rotating curved plate frame 513. Mounting support plates 509 are symmetrically fixedly mounted on both sides of the rotating curved plate frame 513 on the inner side of the cooling cover 501. A rotating spray strip 510 is rotatably mounted between the two mounting support plates 509 via a bearing. A rectangular mounting frame 511 is fixedly mounted on one side of the rotating spray strip 510. A swing column 512 is rotatably mounted inside the rectangular mounting frame 511 via a bearing. One end of the swing column 512 located outside the rectangular mounting frame 511 is rotatably connected to the rotating curved plate frame 513 via a bearing.

[0045] During operation, after the cooling cover 501 is closed, the drive motor 502 is started. The drive motor 502 drives the drive rotating plate 505 to rotate. The drive rotating plate 505 drives the connecting shaft 504 to rotate synchronously through the connecting column 506, realizing unified power transmission across multiple workstations. The drive rotating plate 505 pushes and pulls the linkage rotating plate 507 through the connecting strip 508 to make reciprocating oscillations. The linkage rotating plate 507 drives the rotating curved plate frame 513 to rotate. The rotating curved plate frame 513 drives the swing column 512 to rotate adaptively within the rectangular mounting frame 511, thus... The rotary motion is converted into the up-and-down swinging of the rotating spray bar 510. The rotating spray bar 510 uses the mounting support plate 509 as a fulcrum and continuously swings and sprays inside the cooling hood 501. In conjunction with the rotation of the aluminum ingot body 4, it achieves segmented gradient cooling of the surface of the aluminum ingot body 4 without dead angles, thereby improving the cooling uniformity and the forming quality of the aluminum ingot body 4. The internal spaces of the three cooling hoods 501 are independent of each other, and the rotating spray bar 510 on the inner wall of the three cooling hoods 501 sprays water mist of different sizes and decreasing in size, thereby achieving different cooling effects.

[0046] Working principle of this invention:

[0047] The aluminum ingot bodies 4 to be cooled are placed sequentially at intervals at the top of the feeding end of the conveying mechanism 1. The dual-output shaft motor 105 is started to drive the two push turntables 106 on both sides to rotate synchronously. The push protrusions 107 on the push turntable 106 periodically engage with the slots of the intermittent turntable 109, causing the intermittent turntable 109 to rotate intermittently. The intermittent turntable 109 drives all the linked turntables 104 to move synchronously through the linkage bar 110, which in turn drives the conveyor wheel 102 and the conveyor wheel 2 103 to rotate intermittently in the same direction and rhythm, so as to smoothly and accurately convey the aluminum ingot bodies 4 sequentially to the cooling station directly below the three sets of cooling shrouds 501. The aluminum ingot bodies 4 arrive at the cooling station. After positioning, under the synchronous transmission of the linkage bar 211, the push turntable 209 rotates synchronously with the conveying mechanism 1, and drives the intermittent turntable 207 to rotate intermittently. The intermittent turntable 207 drives the connecting turntable 204 and the rotating crankshaft 206 to make circular motion. The rotating crankshaft 206 pushes the concave slide 202 to slide up and down along the mounting slide 201, so that the fixed top block 203 supports and positions the cooling cover 501, ensuring that the cooling cover 501 is stably and completely fastened and covers the surface of the aluminum ingot body 4, forming an independent and closed cooling space. The cooling spaces inside the three sections of the cooling cover 501 do not cross airflow or temperature, providing a stable environment for segmented gradient cooling.

[0048] While the cooling cover 501 is closed, the crankshaft 206 pushes the concave slide 302 along the limiting slide bar 301 to slide upward through the push slide groove 303. The concave slide 302 drives the lifting top plate 304 to move upward synchronously, so that the top rotating disk 306 is tightly attached to the bottom of the aluminum ingot body 4, and the aluminum ingot body 4 is lifted smoothly and completely separated from the first transmission wheel 102 and the second transmission wheel 103. The push turntable 209 drives the linkage shaft 208 and the drive bevel gear 210 to rotate. The drive bevel gear 210 meshes with the driven bevel gear 309 to drive the rotating sleeve 308 to rotate. The rotating sleeve 308 drives the rotating column 305 and the rotating disk 306 to rotate synchronously through the sliding cooperation of the limiting slide groove 311 and the limiting protrusion 310, thereby driving the aluminum ingot body 4 to rotate at a uniform speed inside the cooling cover 501.

[0049] After the aluminum ingot body 4 enters the rotation state, the drive motor 502 is started to drive the drive rotating plate 505 to rotate, and drives the connecting shaft 504 to rotate synchronously through the connecting column 506, realizing unified power transmission of the three cooling stations. The drive rotating plate 505 pushes and pulls the linkage rotating plate 507 through the connecting bar 508 to make reciprocating swing. The linkage rotating plate 507 drives the inner rotating curved plate frame 513 to make rotary motion. The rotating curved plate frame 513 drives the swing column 512 to rotate adaptively within the rectangular mounting frame 511, converting the rotary motion into the up and down swing of the rotating spray bar 510. The rotating spray bar 510 uses the mounting support plate 509 as the fulcrum and continuously swings and sprays the cooling medium inside the cooling hood 501. The three cooling hoods 501 are independent of each other, and the internal rotating spray bar 510 sprays out the cooling medium in sequence from large to small. The small water mist, with its gradually decreasing cooling intensity, combined with the rotation of the aluminum ingot body 4, achieves segmented gradient cooling: rapid cooling in the first stage, uniform temperature control in the second stage, and stable and slow cooling in the third stage. This completely eliminates problems such as cooling dead zones, localized sudden cooling, excessive internal stress, deformation, and cracking. After a single stage of cooling is completed, the intermittent lifting mechanism 2 and the lifting and rotating mechanism 3 are reset, the cooling cover 501 is lifted, and the aluminum ingot body 4 falls back onto the surface of the first conveyor wheel 102 and the second conveyor wheel 103. The conveying mechanism 1 continues to operate intermittently, sending the aluminum ingot body 4 to the next cooling station. At the same time, a new aluminum ingot body 4 is sent to the first cooling station. The three stations operate simultaneously and continuously, realizing automated, efficient, and high-quality mass production of the aluminum ingot body 4 during forming and cooling.
