Technical Field

[0001] This invention belongs to the field of machining and manufacturing technology, specifically an aluminum alloy liquid cooling plate stamping device and its working method. Background Technology

[0002] With the rapid development of new energy vehicles and power battery technology, liquid cooling plates, as a core component in the battery thermal management system, directly affect the safety, efficiency, and lifespan of power batteries. However, existing liquid cooling plate stamping equipment still has certain shortcomings in terms of processing precision, production efficiency, and equipment adaptability, which restricts the large-scale, efficient production of liquid cooling plates.

[0003] A search revealed a liquid-cooled sheet stamping integrated forming equipment with publication number CN119098514B, published on April 29, 2025. This patent achieves cyclic feeding and synchronous stamping of liquid-cooled sheets by synchronously driving an active synchronous pulley and a transmission crankshaft with a servo motor. It also limits and positions the liquid-cooled sheet before stamping, thereby improving processing speed and shaping efficiency. However, in this technical solution, the positioning device relies on a mechanical guiding structure, which may result in insufficient positioning accuracy, especially when processing liquid-cooled sheets made of aluminum alloy, where positional deviations due to material deformation characteristics are difficult to completely avoid. Furthermore, while the equipment has a high degree of automation, it is only suitable for processing liquid-cooled sheets of specific specifications, exhibiting poor adaptability to liquid-cooled sheets of different sizes or shapes, thus limiting its application range.

[0004] A search revealed a manufacturing process for a stamped liquid cooling plate, publication number CN114985859B, published on July 25, 2023. This patent optimizes the liquid cooling plate manufacturing process by reducing the number of molds used, thereby lowering development costs and time. However, in this technical solution, the stamped flow channel plate blank and the flat plate blank need to be welded together. The welding process may introduce thermal stress, affecting the overall sealing and strength of the liquid cooling plate. Furthermore, this process requires high precision from the stamping equipment; improper control of equipment parameters may lead to deviations in flow channel dimensions, thus affecting the uniformity of coolant flow and heat dissipation.

[0005] The aforementioned problems indicate that existing liquid-cooled plate stamping devices and their manufacturing processes still have certain shortcomings in terms of positioning accuracy, equipment adaptability, sealing performance, and flow channel forming quality. Therefore, this invention provides a novel aluminum alloy liquid-cooled plate stamping device and its operating method, aiming to improve positioning accuracy, enhance the equipment's adaptability to various specifications of liquid-cooled plates, optimize flow channel forming quality, and improve overall sealing performance, thereby meeting the demand for efficient and reliable liquid-cooled plates in the new energy field. Summary of the Invention

[0006] The present invention addresses the problem of providing an aluminum alloy liquid cooling plate stamping device and its operating method, solving the technical problems of insufficient positioning accuracy, poor adaptability, and unstable flow channel forming quality in existing liquid cooling plate stamping equipment. Specifically, the positioning method relying on mechanical guiding structures in the prior art is difficult to avoid positional displacement caused by the deformation characteristics of aluminum alloy materials. Furthermore, the equipment has limited adaptability to liquid cooling plates of different specifications, restricting its application range. In addition, the welding connection between the stamped flow channel plate blank and the flat plate blank may introduce thermal stress, affecting the overall sealing and strength, and the deviation in flow channel dimensions will reduce the uniformity of coolant flow and heat dissipation effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A stamping device for aluminum alloy liquid-cooled plates includes a base, a sliding platform, an adjusting assembly, a stamping assembly, and a positioning assembly. The sliding platform is mounted on top of the base and connected to the base via a linear guide rail. Racks are installed on both sides of the linear guide rail. A drive motor is mounted at the bottom of the sliding platform, and a gear is connected to the output end of the drive motor, meshing with the racks for transmission. An adjusting assembly is mounted on top of the sliding platform. The adjusting assembly includes several adjusting modules, each containing a retractable support rod. One end of the support rod is threaded to the sliding platform, and the other end is fitted with a clamping block, the inner side of which is provided with an elastic washer. The adjusting modules are connected by a linkage mechanism consisting of several hinged rods, each hinged at both ends to the support rod of the adjacent adjusting module.

[0008] The stamping assembly is located above the sliding platform and connected to the base via a lifting mechanism. The lifting mechanism includes a hydraulic cylinder and a guide column. The hydraulic cylinder is fixed to the top of the base, and its piston rod is connected to the top of the stamping assembly. The guide column is vertically mounted on the base, and the stamping assembly is slidably connected to the guide column via a sliding sleeve. A stamping die is mounted at the bottom of the stamping assembly. The stamping die includes an upper die and a lower die. The bottom of the upper die has a protruding stamping head, and the top of the lower die has a groove corresponding to the stamping head. The inner wall of the groove is coated with a wear-resistant coating. Auxiliary cooling channels are located on both sides of the stamping die, and these channels are connected to an external cooling system via pipes.

[0009] The positioning assembly is mounted on the sliding platform and includes several positioning units, each consisting of a positioning block and a fine-tuning mechanism. The positioning block is fixed to the sliding platform with bolts, and a positioning groove is formed on the top of the positioning block, into which a magnetic adsorption piece is embedded. The fine-tuning mechanism includes a stepper motor and a lead screw. The stepper motor is fixed to the bottom of the sliding platform, and its output end is connected to the lead screw, which passes through the positioning block and is threaded into it.

[0010] A method for operating an aluminum alloy liquid-cooled plate stamping device, the specific operating steps of which are as follows: Step 1: Place the aluminum alloy sheet to be processed on the sliding platform. Adjust the position of the sheet using the adjustment components. The specific process is as follows: The drive motor drives the gear to rotate, and the gear meshes with the rack to move the sliding platform along the linear guide to the initial position. Subsequently, the support rod in the adjustment module extends and retracts through the screw rotation. The clamping block moves with the support rod and clamps the sheet. The elastic pad contacts the sheet to prevent surface damage. The linkage mechanism operates synchronously to ensure that the relative positions of each adjustment module remain consistent.

[0011] Step 2: Activate the positioning component to accurately position the board. The specific process is as follows: The stepper motor drives the lead screw to rotate, and the lead screw engages with the positioning block threadedly, causing the positioning block to move along the sliding platform to the predetermined position; the magnetic adsorption piece in the positioning groove adsorbs the edge of the board, further fixing the position of the board; the fine-tuning mechanism makes fine adjustments to the position of the positioning block according to the size and shape requirements of the board.

[0012] Step 3: The hydraulic cylinder works to push the stamping assembly down along the guide column, and the stamping die stamps the sheet metal. The specific process is as follows: the stamping head at the bottom of the upper die cooperates with the groove at the top of the lower die to complete the flow channel formation; the cooling medium in the auxiliary cooling channel circulates to reduce the temperature of the die during the stamping process and reduce thermal deformation; after the stamping is completed, the hydraulic cylinder retracts and the stamping assembly is reset.

[0013] Step 4: After stamping is completed, the formed sheet is moved out of the processing area by the sliding platform. The specific process is as follows: the drive motor rotates in the opposite direction, the gear and rack mesh to drive the sliding platform back to the initial position along the linear guide rail; the support rod in the adjustment module retracts, the clamping block releases the sheet, and the finished product is taken out.

[0014] The beneficial effects of this invention are as follows: The design combining a sliding platform and an adjustment component enables precise movement of the sheet metal via a drive motor and rack and pinion transmission. Simultaneously, the support rod and linkage mechanism in the adjustment module work together to ensure the sheet metal remains stable during processing, preventing positional shifts caused by the deformation characteristics of aluminum alloy. The magnetic adsorption plates and fine-tuning mechanism in the positioning component improve positioning accuracy, meeting the processing requirements of liquid-cooled plates of different sizes and shapes. The wear-resistant coating and auxiliary cooling channels in the stamping die effectively extend the die's service life and improve the quality of the flow channel forming. Through the above design, the shortcomings of existing liquid-cooled plate stamping devices in terms of positioning accuracy, equipment adaptability, sealing performance, and flow channel forming quality are resolved, meeting the needs of the new energy field for efficient and reliable liquid-cooled plates.

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.

[0018] Specific implementation examples are given below.

[0019] This invention provides an aluminum alloy liquid cooling plate stamping device and its working method. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings. Figure 1 This is a schematic diagram of the overall structure of the present invention, showing the layout relationship of the base 1, sliding platform 2, adjusting assembly, stamping assembly 10, and positioning assembly. The base 1 serves as the supporting structure for the entire device, with the sliding platform 2 mounted on its top. The sliding platform 2 is connected to the base 1 via a linear guide rail. Racks 5 are provided on both sides of the linear guide rail. A drive motor 3 is mounted on the bottom of the sliding platform 2, and a gear 4 is connected to the output end of the drive motor 3. The gear 4 meshes with the racks 5 for transmission. This allows for precise movement of the sliding platform 2 along the linear guide rail, thereby ensuring the positional adjustment accuracy of the sheet metal to be processed during the processing.

[0020] An adjustment assembly is installed on the top of the sliding platform 2. This assembly includes several adjustment modules, each containing a retractable support rod 6. One end of the support rod 6 is threaded to the sliding platform 2, and the other end is fitted with a clamping block 7. An elastic pad 8 is placed inside the clamping block 7. The adjustment modules are connected by a linkage mechanism 9, which consists of several hinged rods. Each hinged rod's two ends are hinged to the support rod 6 of the adjacent adjustment module. The diagram shows the connection relationship between the support rod 6, clamping block 7, elastic pad 8, and linkage mechanism 9. The support rod 6 extends and retracts via threaded rotation. The clamping block 7 moves with the support rod 6 and clamps the plate. The elastic pad 8 contacts the plate to prevent surface damage. The linkage mechanism 9 ensures that the relative positions of the adjustment modules remain consistent, preventing positional shifts caused by the deformation characteristics of the aluminum alloy material.

[0021] The stamping assembly 10 is located above the sliding platform 2 and connected to the base 1 via a lifting mechanism. The lifting mechanism includes a hydraulic cylinder 11 and a guide column 12. The hydraulic cylinder 11 is fixed to the top of the base 1, and its piston rod is connected to the top of the stamping assembly 10. The guide column 12 is vertically mounted on the base 1, and the stamping assembly 10 is slidably connected to the guide column 12 via a sliding sleeve. A stamping die is mounted at the bottom of the stamping assembly 10. The stamping die includes an upper die 13 and a lower die 14. The upper die 13 has a protruding stamping head 15 at its bottom, and the lower die 14 has a groove 16 corresponding to the stamping head 15 at its top. The inner wall of the groove 16 is coated with a wear-resistant coating. Auxiliary cooling channels 17 are provided on both sides of the stamping die, and these channels are connected to an external cooling system via pipes. As can be seen from the figure, the stamping head 15 of the upper die 13 and the groove 16 of the lower die 14 cooperate to complete the flow channel forming. The auxiliary cooling channel 17 is rationally positioned, effectively reducing the die temperature during stamping and minimizing thermal deformation.

[0022] The positioning assembly is mounted on the sliding platform 2. The positioning assembly includes several positioning units, each consisting of a positioning block 18 and a fine-tuning mechanism. The positioning block 18 is fixed to the sliding platform 2 by bolts. A positioning groove is formed on the top of the positioning block 18, and a magnetic adsorption piece 19 is embedded within the groove. The fine-tuning mechanism includes a stepper motor 20 and a lead screw 21. The stepper motor 20 is fixed to the bottom of the sliding platform 2, and its output end is connected to the lead screw 21. The lead screw 21 passes through the positioning block 18 and is threadedly engaged with it. The figure shows the composition and installation method of the positioning block 18, the magnetic adsorption piece 19, and the fine-tuning mechanism. When the stepper motor 20 operates, it drives the lead screw 21 to rotate. The lead screw 21, threadedly engaged with the positioning block 18, moves the positioning block 18 along the sliding platform 2 to a predetermined position. The magnetic adsorption piece 19 in the positioning groove adsorbs the edge of the material, further fixing the position of the material. The fine-tuning mechanism makes minor adjustments to the position of the positioning block 18 according to the size and shape requirements of the material, thereby improving positioning accuracy.

[0023] The working method of this invention is as follows: First, the aluminum alloy sheet to be processed is placed on the sliding platform 2, and the position of the sheet is adjusted by the adjustment component. The drive motor 3 drives the gear 4 to rotate, and the gear 4 meshes with the rack 5 to drive the sliding platform 2 to move to the initial position along the linear guide rail. Subsequently, the support rod 6 in the adjustment module extends and retracts through threaded rotation, and the clamping block 7 moves with the support rod 6 and clamps the sheet. The elastic pad 8 contacts the sheet to prevent surface damage. The linkage mechanism 9 operates synchronously to ensure that the relative positions between the adjustment modules remain consistent. Next, the positioning component is activated to accurately position the sheet. The stepper motor 20 drives the lead screw 21 to rotate, and the lead screw 21 engages with the positioning block 18 threadedly, causing the positioning block 18 to move along the sliding platform 2 to the predetermined position. The magnetic adsorption piece 19 in the positioning groove adsorbs the edge of the sheet, further fixing the position of the sheet. The fine-tuning mechanism makes minor adjustments to the position of the positioning block 18 according to the size and shape requirements of the sheet.

[0024] Hydraulic cylinder 11 operates to push stamping assembly 10 down along guide post 12, and stamping die stamps the sheet metal. The stamping head 15 at the bottom of upper die 13 engages with the groove 16 at the top of lower die 14 to complete the flow channel formation. Cooling medium circulates in auxiliary cooling channel 17 to reduce die temperature during stamping and minimize thermal deformation. After stamping, hydraulic cylinder 11 retracts, and stamping assembly 10 resets. Finally, after stamping, the formed sheet metal is removed from the processing area via sliding platform 2. Drive motor 3 rotates in the opposite direction, and gear 4 meshes with rack 5, causing sliding platform 2 to return to its initial position along linear guide rail. Support rod 6 in adjustment module retracts, clamping block 7 releases the sheet metal, and the finished product is removed.

[0025] This invention utilizes a design combining a sliding platform 2 with an adjustment component, employing a drive motor 3 and rack and pinion transmission to achieve precise movement of the sheet metal. Simultaneously, the support rod 6 and linkage mechanism 9 in the adjustment module work together to ensure the sheet metal remains stable during processing. The magnetic adsorption plate 19 and fine-tuning mechanism in the positioning component improve positioning accuracy, meeting the processing requirements of liquid-cooled plates of different sizes and shapes. The wear-resistant coating and auxiliary cooling channel 17 in the stamping die effectively extend the die's service life and improve the flow channel forming quality. The above design addresses the shortcomings of existing liquid-cooled plate stamping devices in terms of positioning accuracy, equipment adaptability, sealing performance, and flow channel forming quality, meeting the needs of the new energy field for efficient and reliable liquid-cooled plates. To better enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention is further explained below with reference to a specific application scenario.

[0026] In the thermal management system of power batteries for new energy vehicles, the processing requirements for aluminum alloy liquid cooling plates often involve high precision and multiple specifications. To meet this requirement, the stamping device of this invention achieves an efficient and reliable liquid cooling plate manufacturing process through a series of precisely designed mechanical structures and control methods.

[0027] First, during the initial position adjustment phase of the sliding platform 2, after the drive motor 3 starts, its output end drives the gear 4 to rotate. The gear 4 meshes with the rack 5, thereby pushing the sliding platform 2 along the linear guide to the processing starting point. During this process, the gear and rack transmission design ensures the movement accuracy of the sliding platform 2, preventing the plate position from shifting due to transmission errors. Simultaneously, the support rod 6 in the adjustment assembly extends and retracts via threaded rotation, causing the clamping block 7 to move and clamp the aluminum alloy plate. The elastic pad 8 generates moderate elastic deformation when in contact with the plate, ensuring clamping force while preventing damage to the plate surface due to hard contact. The linkage mechanism 9 coordinates the relative positions of the adjustment modules. Through the linkage effect of the hinged rods, the clamping block 7 maintains synchronous movement when clamping the plate, preventing positional deviations caused by the easily deformable nature of the aluminum alloy material.

[0028] Subsequently, the positioning component begins operation to further improve the positioning accuracy of the sheet metal. After the stepper motor 20 starts, its output drives the lead screw 21 to rotate. The lead screw 21 engages with the positioning block 18 via a thread, pushing the positioning block 18 along the sliding platform 2 to a predetermined position. The magnetic adsorption plate 19 within the positioning groove magnetically attracts the edge of the sheet metal, creating a stable fixing effect. During this process, the fine-tuning mechanism makes subtle adjustments to the position of the positioning block 18 according to actual processing requirements. For example, for liquid-cooled plates of different sizes or shapes, the final position of the positioning block 18 can be flexibly changed by controlling the rotation angle and direction of the stepper motor 20, thus adapting to various processing scenarios. This positioning method based on magnetic adsorption and lead screw transmission significantly improves positioning accuracy and reduces errors caused by material deformation characteristics compared to traditional mechanical guiding structures.

[0029] Once the sheet metal is precisely positioned, the hydraulic cylinder 11 pushes the stamping assembly 10 down along the guide post 12. The stamping head 15 at the bottom of the upper die 13 engages with the groove 16 at the top of the lower die 14 to complete the runner forming. During this process, the cooling medium circulating in the auxiliary cooling channel 17 effectively removes the heat generated by the die during stamping, reducing the die temperature and minimizing the impact of thermal expansion on the runner forming accuracy. Furthermore, the wear-resistant coating on the inner wall of the groove 16 of the lower die 14 resists high-intensity friction during stamping, extending the die's service life and ensuring consistent runner forming quality.

[0030] After stamping is completed, hydraulic cylinder 11 retracts, stamping assembly 10 resets, drive motor 3 rotates in the opposite direction, gear 4 and rack 5 re-engage, causing sliding platform 2 to return to its initial position along linear guide rail. At this time, support rod 6 in adjustment module retracts through reverse rotation, clamping block 7 releases the sheet metal, and operator can remove the finished product. The entire processing process, through the synergistic effect of the above mechanical structure and control logic, achieves fully automated operation from sheet metal loading, positioning, stamping to finished product removal.

[0031] As can be seen from the above steps, this invention utilizes gear and rack transmission, magnetic adsorption positioning, lead screw fine adjustment, and auxiliary cooling channels to solve the problems of insufficient positioning accuracy, poor equipment adaptability, and unstable flow channel forming quality in existing technologies. These designs not only improve the efficiency and accuracy of liquid cooling plate processing but also significantly enhance the equipment's adaptability to liquid cooling plates of different specifications, thereby meeting the demand for high-efficiency and reliable liquid cooling plates in the new energy field.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
