Description

Technical Field

[0001] This invention relates to the field of aluminum profile extrusion molding technology, and in particular to a high-strength aluminum profile extrusion molding apparatus for new energy vehicle battery trays. Background Technology

[0002] With the rapid development of new energy vehicles towards lightweight and high safety, the battery tray, as the core structural component that carries the power battery, directly determines the safety of the battery pack and the vehicle's range based on its structural strength, dimensional accuracy, and lightweight level. Currently, most new energy vehicle battery trays are made of high-strength aluminum alloy materials. Among them, extrusion molding has become the mainstream manufacturing process for high-strength aluminum profiles used in battery trays because it can achieve integrated molding of complex irregular cross-sections, has high molding efficiency, and good profile integrity.

[0003] Battery trays are mainly composed of frames, reinforcing ribs, base plates, and cover plates. When processing the frames, reinforcing ribs, and other components, aluminum rods heated to a high temperature are pushed into an extrusion die. The aluminum rods undergo plastic flow within a closed extrusion cylinder and are formed in the die cavity, extruding aluminum profiles that match the battery tray assembly. Since the formed aluminum profiles are still in a high-temperature, soft state when they are demolded, the material is soft and lacks rigidity. Moreover, the aluminum profiles used for battery trays are mostly large-section, multi-reinforcing rib structures. Under high temperatures, they lack effective support and proper cooling, making them prone to deformation problems such as sagging, bending, twisting, warping, and edge collapse. This seriously affects the dimensional accuracy, flatness, and subsequent processing and assembly quality of the aluminum profiles, and may even lead to the scrapping of the profiles. Existing aluminum profiles are generally suspended after extrusion, or are only supported by point or roller supports after extrusion, with no side constraints. In a high-temperature, soft state, they are prone to twisting, warping, and reinforcing rib deformation. Therefore, this paper proposes a high-strength aluminum profile extrusion forming device for new energy vehicle battery trays to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a high-strength aluminum profile extrusion molding apparatus for new energy vehicle battery trays.

[0005] The present invention provides a high-strength aluminum profile extrusion molding device for new energy vehicle battery trays, which adopts the following technical solution:

[0006] A high-strength aluminum profile extrusion forming device for battery trays of new energy vehicles includes an extrusion device body, a fixing plate is provided on one side of the extrusion device body, a mold is provided on the inner side of the fixing plate, and a cooling mechanism is provided on one side of the fixing plate.

[0007] The cooling mechanism includes a frame plate disposed on one side of a fixed plate. Two base plates are slidably connected to the inner side of the frame plate in the front-back direction. A water-cooling pipe and a mesh pipe are disposed on the top of each of the two base plates. The mesh pipe is fixedly connected to the end of the water-cooling pipe. The water-cooling pipe and the mesh pipe are interconnected to form a material feeding chamber. A water-cooling spiral cavity is provided inside the pipe wall of the water-cooling pipe. The water-cooling spiral cavity is arranged around the outside of the material feeding chamber. An annular plate is fixedly connected to the top of the base plate. The annular plate is sleeved on the outside of the mesh pipe. Multiple fans are fixedly connected to the inner side of the annular plate. The multiple fans are arranged at equal intervals around the circumference of the annular plate. An ejection assembly is disposed on the outer side of the main body of the extrusion device. The ejection assembly is used to eject the formed parts that have entered the water-cooling pipe and the mesh pipe.

[0008] By adopting the above technical solution, a segmented cooling structure is used, which employs a front-end water-cooled pipe conformal support for water cooling and a rear-end grid pipe surrounding fan for air cooling. This allows the formed aluminum profile to directly enter the feeding cavity that matches the workpiece contour after demolding, receiving circumferential rigid support throughout the process. This effectively solves the problems of large-section, multi-reinforced battery tray aluminum profiles being prone to sagging, bending, twisting, warping, and edge collapse when suspended in a soft state at high temperatures. At the same time, the rapid shaping with water cooling followed by gradual air cooling avoids the excessive temperature difference between the inside and outside of the profile caused by strong water cooling alone, which can generate residual internal stress. This improves the dimensional accuracy, flatness, and structural stability of the finished product, resulting in higher safety.

Two second hoses are fixedly connected to the water inlet of the cooling pipe. Two connectors are fixedly connected to the outside of each of the two water-cooling pipes. The four connectors are respectively connected to the water inlet and outlet of the corresponding water-cooling spiral cavity. Two connectors are detachably and fixedly connected to the two second hoses, and the remaining two connectors are detachably and fixedly connected to the two first hoses. A nozzle is provided on the top of the housing, and the nozzle is fixedly connected to the water outlet of the cooling pipe.

[0014] By adopting the above technical solution, the coolant used for cooling is sprayed downwards into the tank through the nozzle for recycling.

[0015] Preferably, a first support plate is fixedly connected to both the front and rear sides of the housing, and a second support plate is fixedly connected to the outside of the cooling pipe, with one end of the second support plate fixedly connected to one side of the housing.

[0016] By adopting the above technical solution, the first support plate provides support for the box body.

[0017] Preferably, the ejection assembly includes two track frames, which are respectively disposed on the front and rear sides of the extrusion device body. A movable block is slidably connected inside the track frame in the left-right direction. A pusher plate is fixedly connected to the side of the movable block facing the water cooling pipe. The outer contour of the pusher plate is adapted to fit the contour of the material feeding chamber.

[0018] By adopting the above technical solution, the pusher plate pushes the molded part out of the water-cooling pipe and the mesh pipe.

[0019] Preferably, a threaded control rod is rotatably connected inside the track frame, the threaded control rod passes through the movable block and is threadedly connected to the movable block, and a second motor is fixedly connected to the outside of the track frame, the second motor being fixedly connected to one end of the threaded control rod through an output shaft.

[0020] By adopting the above technical solution, the second motor drives the threaded control rod to rotate.

[0021] Preferably, a limiting groove is formed on the inner side of the fixing plate, and the mold extends into the limiting groove and is adapted to the limiting groove.

[0022] By adopting the above technical solution, the limiting groove improves the stability of the mold after it is placed in the mold.

[0027] In summary, the present invention has the following beneficial technical effects:

[0028] 1. A high-strength aluminum profile extrusion molding device for new energy vehicle battery trays adopts a segmented cooling structure with front-end water-cooled pipe contour support for water cooling and rear-end grid pipe surrounding fan for air cooling. This allows the formed aluminum profile to directly enter the feeding cavity that matches the workpiece contour after demolding, receiving circumferential rigid support throughout the process. This effectively solves the problems of large-section, multi-reinforcement battery tray aluminum profiles being prone to sagging, bending, twisting, warping, and edge collapse deformation when suspended in a soft state at high temperatures. At the same time, the device uses water cooling for rapid shaping followed by gradient air cooling to avoid excessive internal stress caused by a single strong water cooling, which can lead to excessive temperature difference between the inside and outside of the profile. This improves the dimensional accuracy, flatness, and structural stability of the finished product, resulting in higher safety.

[0029] 2. A high-strength aluminum profile extrusion forming device for new energy vehicle battery trays, equipped with two sets of water-cooled pipes and mesh pipes that can be used interchangeably. With the help of a dedicated ejection component, one station can simultaneously perform extrusion cooling and the other station can simultaneously push and discharge materials, eliminating the need to stop the machine to wait for the profiles to cool and unload. This significantly improves the continuous operation efficiency of aluminum profile extrusion forming. Furthermore, the water-cooled pipes and mesh pipes can be assembled with detachable bolts through the positioning plate and the base plate, allowing for quick replacement of pipes with different cavity specifications. This device is suitable for extrusion processing of aluminum profiles for battery trays with different cross-sectional shapes, and has a wide range of applications and is convenient to replace and maintain.

[0030] 3. The coolant is set up with a closed-loop circulation system consisting of a housing, water pump, distribution box and pipeline. After heat exchange in the water-cooled spiral cavity, the coolant is sprayed back to the housing by the nozzle. During the spraying process, it is in full contact with the air to dissipate heat naturally, so as to realize the continuous cooling of the coolant circulation and ensure the stable and uniform cooling effect of water cooling. At the same time, the mold adopts the positioning of the limiting groove and the top pressure plate can be detached and pressed and fixed, which has the advantages of convenient disassembly and replacement.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be described in further detail below.

[0041] This invention discloses an extrusion molding apparatus for high-strength aluminum profiles used in battery trays for new energy vehicles. (Refer to...) Figures 1-8 It includes an extrusion device body 1, a fixing plate 2 on one side of the extrusion device body 1, a mold 3 on the inner side of the fixing plate 2, and a cooling mechanism 4 on one side of the fixing plate 2.

[0042] The cooling mechanism 4 includes a frame plate 41, which is disposed on one side of the fixed plate 2. Two base plates 42 are slidably connected to the inner side of the frame plate 41 in the front-back direction. Water cooling pipes 43 and mesh pipes 44 are provided on the top of the two base plates 42. The mesh pipes 44 are fixed to the ends of the water cooling pipes 43. The water cooling pipes 43 and mesh pipes 44 are connected to form a material feeding chamber 45. A water cooling spiral cavity 46 is provided in the wall of the water cooling pipes 43. The water cooling spiral cavity 46 is arranged around the outside of the material feeding chamber 45. An annular plate 47 is fixedly connected to the top of the base plate 42. The annular plate 47 is sleeved on the outside of the mesh pipes 44. Multiple fans 48 are fixedly connected to the inner side of the annular plate 47. The multiple fans 48 are arranged around the annular plate 47 at equal intervals. An ejection assembly 5 is provided on the outer side of the extrusion device body 1. The ejection assembly 5 is used to eject the molded parts that have entered the water cooling pipes 43 and mesh pipes 44.

[0043] The main body 1 of the extrusion device in this device is an existing extrusion structure, so it will not be described in detail here. In the specific implementation process, the mold 3 is provided with slots. The heated aluminum rod is pushed into the mold 3 by the main body 1 of the extrusion device. After passing through the slots, the aluminum rod is extruded and shaped. After passing through the slots, the required battery tray molding part is formed. The two base plates 42 set in this device can move back and forth synchronously inside the frame plate 41. When a single water cooling pipe 43 is on one side of the mold 3, the extruded battery tray molding part directly enters the interior of the water cooling pipe 43. The contour of the material flow chamber 45 of the water cooling pipe 43 and the mesh pipe 44 matches the shape of the molding part. That is, after the molding part enters the interior of the water cooling pipe 43 and the mesh pipe 44, it can effectively contact the interior of the material flow chamber 45, thereby providing rigid support for the molding part. This can effectively avoid the situation of falling, bending and twisting that may occur due to the molding part not being cooled before direct suspension of material discharge.

[0044] The ejection assembly 5 in this device pushes the molded part into the water-cooling pipe 43. After the molded part detaches from the mold 3 and enters the water-cooling pipe 43, the water-cooling pipe 43 is moved to one side of the ejection assembly 5. At this time, another water-cooling pipe 43 can be moved to one side of the mold 3 to continue the cooling task. This arrangement of two sets of water-cooling pipes 43 and mesh pipes 44 allows for alternating use, enabling simultaneous cooling and extrusion, ensuring processing efficiency. The surface of the molded part inside the water-cooling pipe 43 is in full contact with the inner wall of the water-cooling pipe 43. Coolant is injected into the water-cooled spiral cavity 46 inside the water-cooling pipe 43. During the flow of the coolant, the inner wall of the water-cooling pipe 43 can be cooled by water, thereby achieving the purpose of cooling the molded part. As the molded part is pushed into the mesh tube 44, the airflow blown out by the fan 48 outside the mesh tube 44 can directly contact the molded part through the gaps in the mesh tube 44, thereby achieving the purpose of cooling the molded part inside the mesh tube 44 by air, until the molded part is pushed out from the mesh tube 44, completing the entire cooling process.

[0045] Multiple positioning plates 49 are fixedly connected to the outside of the water cooling pipe 43 and the mesh pipe 44. Multiple grooves are opened on the top of the base plate 42. The multiple positioning plates 49 extend into the multiple grooves one by one, and the positioning plates 49 are connected to the base plate 42 by bolts.

[0046] The positioning plate 49 is inserted into the groove and connected by bolts to form a detachable installation. The advantage of this design is that when different shapes of battery tray parts need to be extruded and molded, the water cooling pipe 43 and the mesh pipe 44 can be easily replaced, so that the material passage chamber 45 of the water cooling pipe 43 and the mesh pipe 44 after replacement can be adapted to the corresponding shape of battery tray parts, and the adaptation range is wider.

[0047] A threaded adjusting rod 491 is rotatably connected to the inner side of the frame plate 41. The threaded adjusting rod 491 passes through the two base plates 42 in sequence, and the threaded adjusting rod 491 is connected to the two base plates 42 by threads respectively. A first motor 492 is fixedly connected to the outside of the frame plate 41. The first motor 492 is fixedly connected to one end of the threaded adjusting rod 491 through the output shaft.

[0048] The first motor 492 is used to drive the threaded adjusting rod 491 to rotate. After the threaded adjusting rod 491 rotates, it drives the two base plates 42 to move back and forth synchronously, thereby controlling the two base plates 42 to stop on one side of the mold 3 in turn, so that the two sets of water cooling pipes 43 and mesh pipes 44 can be used alternately.

[0049] A housing 493 is installed above the frame plate 41. A water pump 494 is fixedly installed on the outside of the housing 493. The water pump 494 is connected to the housing 493 through a connecting pipe. The outlet of the water pump 494 is connected to a distribution box 495 through a pipe. Two first flexible hoses 497 are fixedly connected to one side of the distribution box 495. A cooling pipe 496 is installed on the side of the housing 493 away from the water pump 494. Two second flexible hoses 499 are fixedly connected to the inlet of the cooling pipe 496. The two water-cooling pipes 43 are externally... Each of the two water-cooling pipes 43 is fixedly connected to two connectors 498. A total of four connectors 498 are provided for the two water-cooling pipes 43. The four connectors 498 are respectively connected to the inlet and outlet of the corresponding water-cooling spiral cavity 46. Two connectors 498 are detachably and fixedly connected to two second hoses 499, and the remaining two connectors 498 are detachably and fixedly connected to two first hoses 497. A nozzle 481 is provided on the top of the housing 493. The nozzle 481 is fixedly connected to the outlet of the cooling pipe 496.

[0050] Coolant is injected into the housing 493. The water pump 494 draws the coolant from the housing 493 into the distribution tank 495, and from the distribution tank 495 it enters two first hoses 497. It then passes through the water-cooled spiral chamber 46, the second hose 499, and the cooling pipe 496 in sequence before entering the nozzle 481. The nozzle 481 sprays the coolant downwards, dividing it into multiple streams that are sprayed downwards into the housing 493. This achieves the circulation of the coolant and cools it during the flow, ensuring the quality of cooling. The nozzle 481 is positioned above the housing 493 with a certain distance between it and the housing. The advantage of this design is that as the coolant enters the housing 493, it is sprayed out by the nozzle 481, forming multiple fine streams of water that are directly exposed to the air, which improves the cooling effect of the coolant.

[0051] The front and rear sides of the housing 493 are fixedly connected to the first support plate, and the cooling pipe 496 is fixedly connected to the outside of the second support plate. One end of the second support plate is fixedly connected to one side of the housing 493.

[0052] The first support plate provides support for the housing 493, while the second support plate supports the cooling pipe 496.

[0053] The ejection component 5 includes two track frames 51, which are respectively located on the front and rear sides of the extrusion device body 1. Inside the track frame 51, a movable block 52 is slidably connected in the left and right direction. A pusher plate 53 is fixedly connected to the side of the movable block 52 facing the water cooling pipe 43. The outer contour of the pusher plate 53 is adapted to fit the contour of the material feeding chamber 45.

[0054] When the molded part enters the interior of a water-cooling pipe 43 and separates from the mold 3, the water-cooling pipe 43 is stopped on the side of the corresponding pusher plate 53. The molded part can be pushed towards the mesh pipe 44 by controlling the movement of the pusher plate 53 until it is pushed out of the mesh pipe 44 to complete the unloading. The purpose of setting two push-out components 5 is that when the two water-cooling pipes 43 are used alternately, each water-cooling pipe 43 can correspond to one of the push-out components 5 when it needs to push out the internal molded part, so as to ensure the smooth operation of cooling and pushing.

[0055] A threaded control rod 54 is rotatably connected inside the track frame 51. The threaded control rod 54 passes through the movable block 52 and is connected to the movable block 52 by a thread. A second motor 55 is fixedly connected to the outside of the track frame 51. The second motor 55 is fixedly connected to one end of the threaded control rod 54 through its output shaft.

[0056] The second motor 55 drives the threaded control rod 54 to rotate, and the threaded control rod 54 drives the movable block 52 to move horizontally inside the track frame 51. The movable block 52 drives the pusher plate 53 to move.

[0057] A limiting groove 6 is provided on the inner side of the fixing plate 2, and the mold 3 extends into the limiting groove 6 and is adapted to the limiting groove 6.

[0058] When the mold 3 is placed inside the fixed plate 2, the mold 3 is limited by the limiting groove 6, which can prevent the mold 3 from shaking inside the fixed plate 2.

[0059] A top pressure plate 7 is provided on the top of the fixed plate 2. The bottom of the top pressure plate 7 is in contact with the top of the mold 3. The top pressure plate 7 is connected to the fixed plate 2 by bolts. A material support plate 8 is provided on the side of the fixed plate 2 facing the body 1 of the extrusion device. A connecting plate is fixedly connected between the material support plate 8 and the fixed plate 2.

[0060] The purpose of setting the top pressure plate 7 on the top of the fixed plate 2 is to press and fix the mold 3 inside the fixed plate 2. The top pressure plate 7 and the fixed plate 2 are detachably connected. When the top pressure plate 7 is removed, the mold 3 can be replaced. This allows for flexible adaptation to the extrusion processing requirements of battery trays of different shapes. The heated aluminum rod is placed on the material support plate 8, and then the extrusion device body 1 pushes the aluminum rod placed on the material support plate 8 toward the mold 3 for extrusion.

[0061] A frame 9 is fixedly connected between the frame plate 41 and the fixed plate 2. A slider 10 is slidably connected inside the frame 9 in the left and right direction. A robotic arm 11 is fixedly connected to the top of the slider 10. An electric push rod 12 is fixedly connected inside the frame plate 41. The telescopic end of the electric push rod 12 is fixedly connected to one side of the slider 10.

[0062] When the molded part is extruded, the electric push rod 12 can drive the slider 10 to move left and right. The slider 10 drives the robotic arm 11 to move left and right between the frame plate 41 and the fixed plate 2. The robotic arm 11 can clamp the end of the molded part in the mold 3 and pull it towards the water cooling pipe 43, so as to avoid the situation where the end of the molded part is inside the mold 3 and cannot be pushed out and discharged in time.

[0063] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
