Description

Technical Field

[0001] This invention belongs to the field of metal profile processing technology, specifically relating to a profile cutting system and method for producing heat-dissipating automotive packaging boxes. Background Technology

[0002] Adding radiator coils to automotive packaging significantly improves heat dissipation efficiency, ensuring stable temperatures for critical vehicle components (such as engines and battery packs) during transportation. The coils, by uniformly distributing the heat dissipation medium (such as air or coolant), accelerate heat conduction and diffusion, preventing localized overheating that could lead to material aging or performance degradation. Especially for new energy vehicles, radiator coils effectively mitigate the risk of high battery pack temperatures and extend battery life. Copper tubing itself has a high thermal conductivity, far exceeding that of ordinary steel, enabling rapid heat transfer. When fabricated into a serpentine radiator coil, its spiral structure further increases the contact area with air and enhances heat exchange efficiency through turbulence. Copper tubing also exhibits excellent ductility and fatigue resistance, making it suitable for processing into spiral structures without easily cracking. Due to its thermal conductivity, structural stability, and processing adaptability, copper tubing is an ideal material for fabricating serpentine radiator coils. During the fabrication of serpentine radiator coils, copper tubing requires segmentation using a cutting system.

[0003] Existing profile cutting systems for producing heat-dissipating automotive packaging boxes have several shortcomings. First, they are not suitable for segmented cutting of copper tube profiles with arched cross-sections. They cannot prevent deformation of the copper tube profiles at the cutting points during the cutting process. Copper tube profiles with arched cross-sections can increase the contact area between the serpentine heat dissipation coil and the inner or outer wall of the packaging box, thereby improving heat transfer efficiency. Second, they cannot laminate stainless steel strips onto the flat part of the copper tube profile, which may cause the serpentine heat dissipation coil to deform due to thermal expansion or mechanical stress in the subsequent fabrication process.

[0004] In view of this, the inventors hope to optimize and improve the existing profile cutting system for producing heat-dissipating automotive packaging boxes. Summary of the Invention

[0005] The purpose of this invention is to overcome at least one of the above-mentioned problems in the prior art and to provide a profile cutting system and method for producing heat-dissipating automotive packaging boxes.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: This invention provides a profile cutting system for the production of heat-dissipating automotive packaging boxes, including a copper tube pushing assembly, a steel strip opening assembly, a copper tube stamping assembly, a riveting assembly, and a cutting assembly; The copper tube pushing component is located on the left side of the composite station and is used to clamp and push the arched copper tube profile to the composite station. The steel strip perforation assembly is located on the right side of the composite station and is used to drill shaped step holes in the steel strip profile and clamp and push the steel strip profile to the composite station. The copper tube stamping assembly is located on the upper side of the composite station and is used to stamp and form a hollow riveting pipe that extends into the corresponding stepped hole on the straight part of the copper tube profile in the composite station. The riveting assembly is located on the lower side of the composite work station and is used to press the outer end of the hollow riveting tube to deform it and form a riveting heat-conducting head that is confined in the stepped hole. The cutting assembly is positioned above the copper tube pushing assembly at the composite workstation and is used to cut the composite profile to a fixed length.

[0007] Furthermore, in the above-mentioned profile cutting system for producing heat-dissipating automotive packaging boxes, copper tube pushing components and steel strip opening components are respectively provided on both sides of the riveting component, the copper tube stamping component is located above the steel strip opening component, and the cutting component is located above the area between the copper tube pushing component and the riveting component.

[0008] Furthermore, in the above-mentioned profile cutting system for producing heat-dissipating automotive packaging boxes, the copper tube pushing component includes an arched outer frame. The shape of the arched outer frame matches the cross-sectional shape of the copper tube profile. Several first support rollers for supporting the copper tube profile are installed on the inner wall of the arched outer frame. At least one of the first support rollers serves as a first active roller and is driven to rotate by a first motor via a first anti-slip belt transmission component.

[0009] Furthermore, in the aforementioned profile cutting system for producing heat-dissipating automotive packaging boxes, the steel strip perforation assembly includes a frame base. The frame base has a clearance area on one side near the riveting assembly and a clamping area on the other side. The bottom surface of the clearance area and the inner wall of the clamping area are respectively equipped with several second support rollers for supporting the steel strip profile. At least one of the second support rollers serves as a second active roller and is driven to rotate by a second motor via a second anti-slip belt transmission component. The clamping area is symmetrically provided with rectangular protrusions on its upper and lower sides. The rectangular protrusions have sliding restrictions on a support plate inside. The support plate is sleeved on the outside of a high-precision lead screw. The high-precision lead screw is driven to rotate by a lead screw motor fixed on the frame base. Several drilling motors are symmetrically installed on the inner side of the support plate. The upper drilling motor has a first drill bit installed at its output end for forming a narrow groove, and the lower drilling motor has a second drill bit installed at its output end for forming a wide groove. The narrow groove and the wide groove together form a stepped hole.

[0010] Furthermore, in the aforementioned profile cutting system for producing heat-dissipating automotive packaging boxes, the copper tube stamping assembly includes a linear guide pair, a support plate, an arched inner support frame, a first stamping push rod, a first heating plate, and a convex tube forming punch rod. The slide rail of the linear guide pair is fixed on the base plate. The slider of the linear guide pair is supported by the support plate and has an arched inner support frame that fits against the inner wall of the copper tube profile. Several first stamping push rods are installed side by side on the top wall of the cavity of the arched inner support frame. Two convex tube forming punch rods for stamping hollow riveting pipes are symmetrically installed on the movable end of the first stamping push rod via the first heating plate. The bottom plate of the arched inner support frame has several sets of guide holes to facilitate the passage of the convex tube forming punch rods.

[0011] Furthermore, in the above-mentioned profile cutting system for producing heat-dissipating automotive packaging boxes, the riveting assembly includes a pressure-bearing platform seat. The upper end of the pressure-bearing platform seat is provided with several guide grooves. A second stamping push rod is installed below each guide groove on the pressure-bearing platform seat. The movable end of the second stamping push rod is connected to a guide slide plate that is slidably restricted in the guide groove. Two riveting blocks are symmetrically installed on the upper side of the guide slide plate to facilitate riveting the outer end of the hollow riveting tube and forming a riveting heat-conducting head.

[0012] Furthermore, in the above-mentioned profile cutting system for producing heat-dissipating automotive packaging boxes, the length of the pressure-bearing platform seat is matched with the fixed-length cutting value of the composite profile.

[0013] Furthermore, in the above-mentioned profile cutting system for producing heat-dissipating automotive packaging boxes, the thickness of the riveting heat-conducting head is equal to or less than the axial depth of the wide groove in the stepped hole.

[0014] Furthermore, in the aforementioned profile cutting system for producing heat-dissipating automotive packaging boxes, the cutting assembly includes a base, a drive push rod, a guide telescopic rod, a movable plate, a vertical plate, a cutting motor, a third anti-slip belt transmission component, a rotating shaft, and a cutting blade. The drive push rod and the guide telescopic rod are installed between the base and the movable plate. The vertical plate is vertically fixed to the lower side of the movable plate. The cutting motor is installed on the upper part of the vertical plate. The rotating shaft is rotatably supported on the lower part of the vertical plate. One end of the rotating shaft is connected to the output shaft of the cutting motor via the third anti-slip belt transmission component, and the other end of the rotating shaft is equipped with a cutting blade.

[0015] This invention also provides a method for cutting metal profiles, based on the aforementioned profile cutting system for producing heat-dissipating automotive packaging boxes, comprising the following steps: S1. Use the copper tube pushing assembly to clamp and push the copper tube profile with an arched cross section to the composite station. Use the steel strip opening assembly to drill a shaped step hole on the steel strip profile and clamp and push the steel strip profile to the composite station. S2. Using a copper tube stamping assembly, a hollow riveting tube extending into the corresponding stepped hole is formed on the straight part of the copper tube profile in the composite station. S3. Use a riveting assembly to press and deform the outer end of the hollow riveting tube and form a riveting heat-conducting head that is confined in the stepped hole. S4. The cutting assembly is used to cut composite profiles to a fixed length. During the cutting process, the arched inner support frame of the copper tube stamping assembly stays inside the copper tube profile to provide internal support for the cutting. S5. After the cutting is completed, the arched inner support frame of the copper tube stamping assembly is pulled out from the copper tube profile under the drive of the linear guide pair. At this time, the cutting composite profile is transferred by the unloading robot.

[0016] The beneficial effects of this invention are: 1. Adaptable to cutting arched copper tube profiles: The arched outer frame of the copper tube pusher component matches the cross-sectional shape of the copper tube profile, which can effectively prevent deformation of the copper tube profile with an arched cross-section at the cutting point during the cutting process, meet the cutting requirements of special structure copper tube profiles for the preparation of serpentine heat dissipation coils, and improve heat conduction efficiency.

[0017] 2. Achieving Copper Tube and Steel Strip Composite: The steel strip perforation assembly can drill stepped holes in the steel strip profile, and the copper tube stamping assembly can stamp hollow riveting pipes that extend into the corresponding stepped holes in the straight section of the copper tube profile. The riveting assembly rivets these pipes to form a riveted heat-conducting head, thus achieving a composite of the copper tube profile and the steel strip profile. Adding a stainless steel strip can significantly improve structural rigidity and strength. Simultaneously, the stainless steel strip can also serve as a welding transition layer, avoiding the brittle phase or cracking problems that may occur when directly welding copper to the main body of the heat-dissipating automotive packaging box.

[0018] 3. High degree of automation: The controller is connected to the copper tube pushing assembly, steel strip drilling assembly, copper tube stamping assembly, riveting assembly, and cutting assembly, and connects to the back-end terminal via a wireless communication module. It can receive commands from the back-end terminal to achieve automated control of each component, improving production efficiency. A high-precision lead screw drives the feed rate of the steel strip drilling, ensuring that the matching error between the stepped hole and the riveting tube is ≤0.1mm, guaranteeing composite quality. During the riveting process, the riveting force is controlled to ensure that the thickness of the riveting heat-conducting head does not exceed the depth of the wide groove, ensuring good adhesion.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0024] In this embodiment, a copper tube pushing component 2 and a steel strip opening component 3 are respectively provided on both sides of the riveting component 5, a copper tube stamping component 4 is provided above the steel strip opening component 3, and a cutting component 6 is provided above the area between the copper tube pushing component 2 and the riveting component 5.

[0025] like Figure 6 As shown, the copper tube pushing assembly 2 includes an arched outer frame 201. The shape of the arched outer frame 201 matches the cross-sectional shape of the copper tube profile 8. Several first support rollers 202 for supporting the copper tube profile 8 are installed on the inner wall of the arched outer frame 201. At least one of the first support rollers 202 serves as a first active roller and is driven to rotate by a first motor 203 via a first anti-slip belt transmission component. The first motor 203 is fixed inside the arched outer frame 201.

[0026] like Figure 7As shown, the steel strip perforation assembly 3 includes a frame 301. The frame 301 has a clearance area on one side near the riveting assembly and a clamping area on the other side. The clearance area is designed to allow space for the copper tube stamping assembly 4 to move. The clamping area is designed to clamp and transport the steel strip profile 9. Several second support rollers 302 for supporting the steel strip profile 9 are installed on the bottom surface of the clearance area and the inner wall of the clamping area, respectively. At least one of the second support rollers 302 serves as a second active roller and is driven to rotate by a second motor 303 via a second anti-slip belt transmission component. The second motor 303 is fixed to the frame 301. Rectangular protrusions 304 are symmetrically arranged vertically in the clamping area. A support plate 305 slides inside the rectangular protrusions 304, and the support plate 305 is sleeved on the outside of a high-precision lead screw 306. The high-precision lead screw 306 is driven to rotate by a lead screw motor 307 fixed to the frame 301. Several drilling motors 308 are symmetrically installed on the inner side of the support plate 305. The upper drilling motor 308 has a first drill bit 309 installed at its output end for forming a narrow groove 901, and the lower drilling motor 308 has a second drill bit 310 installed at its output end for forming a wide groove 902. The narrow groove 901 and the wide groove 902 together form a stepped hole.

[0027] like Figure 8 As shown, the copper tube stamping assembly 4 includes a linear guide pair 401, a support plate 402, an arched inner support frame 403, a first stamping push rod 404, a first heating plate 405, and a convex tube forming punch 406. The slide rail of the linear guide pair 401 is fixed on the base plate, and the slider of the linear guide pair 401 is supported by the support plate 402 and has an arched inner support frame 403 that fits against the inner wall of the copper tube profile 8. Several first stamping push rods 404 are installed side by side on the top wall of the cavity of the arched inner support frame 403. Two convex tube forming punches 406 for stamping and forming hollow riveting tubes 801 are symmetrically installed on the movable end of the first stamping push rod 404 via the first heating plate 405. Several sets of guide holes 407 are opened on the bottom plate of the arched inner support frame 403 to facilitate the passage of the convex tube forming punches 406.

[0028] like Figure 9 As shown, the riveting assembly 5 includes a pressure-bearing platform seat 501. The upper end of the pressure-bearing platform seat 501 is provided with several guide grooves 505. A second stamping push rod 502 is installed below each guide groove 505 on the pressure-bearing platform seat 501. The movable end of the second stamping push rod 502 is connected to a guide slide plate 503 that is slidably restricted in the guide groove 505. Two riveting blocks 504 are symmetrically installed on the upper side of the guide slide plate 503 to facilitate riveting the outer end of the hollow riveting tube 801 and forming the riveting heat-conducting head 802.

[0029] In this embodiment, the length of the pressure-bearing platform base 501 is matched with the fixed-length cutting value of the composite profile.

[0030] In this embodiment, the thickness of the riveted heat-conducting head 802 is equal to or less than the axial depth of the wide groove 902 in the stepped hole.

[0031] like Figure 10 As shown, the cutting assembly 6 includes a base 601, a drive push rod 602, a guide telescopic rod 603, a movable plate 604, a vertical plate 605, a cutting motor 606, a third anti-slip belt transmission component 607, a rotating shaft 608, and a cutting blade 609. The drive push rod 602 and the guide telescopic rod 603 are installed between the base 601 and the movable plate 604. The vertical plate 605 is vertically fixed to the lower side of the movable plate 604. The cutting motor 606 is installed on the upper part of the vertical plate 605, and the rotating shaft 608 is rotatably supported on the lower part of the vertical plate 605. One end of the rotating shaft 608 is connected to the output shaft of the cutting motor 606 via the third anti-slip belt transmission component 607, and the cutting blade 609 is installed on the other end of the rotating shaft 608.

[0032] This embodiment also provides a method for cutting metal profiles, including the following steps: S1. The arched outer frame 201 of the copper tube pushing assembly 2 matches the cross-sectional shape of the copper tube profile 8. The first motor 203 drives the first active roller to rotate, clamping and pushing the copper tube profile 8 to the composite station, ensuring that its straight part faces downward. The drilling motor 308 of the steel strip opening assembly 3 starts, and the upper first drill bit 309 drills a narrow groove 901 on the steel strip profile 9. The lower second drill bit 310 drills a wide groove 902 on the steel strip profile 9 simultaneously, generating a stepped hole. Then, the second motor 303 drives the second active roller to push the steel strip profile 9 to the composite station, aligning it with the straight part of the copper tube profile 8. During the pushing process, the arched inner support frame 403 of the copper tube stamping assembly 4 can provide guiding support for the copper tube profile 8.

[0033] S2. The linear guide pair 401 of the copper tube stamping assembly 4 drives the arched inner support frame 403 to insert into the inner cavity of the copper tube to support deformation. The first stamping push rod 404 pushes the convex tube forming punch 406, which has been preheated by the first heating plate 405, to press the straight part of the copper tube downward, forming a hollow riveting tube 801 that extends into the stepped hole of the steel strip. The temperature of the first heating plate 405 is controlled above the recrystallization temperature of the copper tube to ensure the ductility of the material.

[0034] S3. The second stamping push rod 502 of the riveting assembly 5 pushes the guide slide plate 503 and the riveting block 504 upward, applying radial pressure to the outer end of the hollow riveting tube 801, causing it to deform and expand and get stuck in the wide groove 902 of the stepped hole, forming the riveting heat conduction head 802; the riveting force must be uniform to avoid metal fatigue, and the thickness of the riveting heat conduction head does not exceed the depth of the wide groove 902 to ensure fit.

[0035] S4. The controller 1 receives the cutting length instruction from the back-end terminal through the wireless communication module 7, adjusts the stroke of the drive push rod of the cutting component 6, and positions the cutting blade to the target position; the cutting motor 606 drives the rotating shaft 606 and the cutting blade 609 to rotate at high speed through the third anti-slip belt transmission component 607, and presses down along the guide telescopic rod 603 to complete the fixed-length cutting of the composite profile; during the cutting process, the arched inner support frame 403 of the copper tube stamping component 4 stays inside the copper tube profile to provide internal support for cutting.

[0036] S5. After cutting is completed, the arched inner support frame 403 of the copper tube stamping assembly 4 is pulled out from the copper tube profile 8 under the drive of the linear guide pair 401. At this time, the cut composite profile can be transferred using a blanking robot. The cut composite profile is inspected by a vision inspection system or manually to check the integrity of the rivet joint and the flatness of the cut surface. The controller 1 records the process parameters (such as stamping pressure and cutting speed) and uploads them to the background terminal through the wireless communication module 7 to realize production data traceability.

[0037] The key technological points of the above method are: Precision control: The high-precision lead screw drives the feed rate of the steel strip drilling, ensuring that the matching error between the stepped hole and the riveting pipe is ≤0.1mm.

[0038] Safety guidelines: Before operation, check the electrical system and the condition of the cutting tools. Wear protective equipment during cutting to avoid injury from flying metal.

[0039] Efficiency optimization: Modular design (such as replaceable drill bits and punch rods) is adopted to adapt to different profile specifications, reducing changeover time.

[0040] The above steps integrate machining, stamping and quality control technologies, and are suitable for the efficient and automated production of copper tube-steel strip composite profiles.

[0041] The specific process for fabricating heat dissipation coils using copper tube-steel strip composite profiles is as follows: 1. Coil bending and forming The cut copper tube-steel strip composite profile is placed on a professional coil bending machine. This machine must have a precise bending radius control function to ensure that the shape of the coil after bending meets the design requirements.

[0042] Based on the design specifications of the heatsink coil, set parameters such as bending angle and bending radius. For example, for certain heatsink coil specifications, the bending radius may be set to vary from 50mm to 200mm, and the bending angle may be set according to the overall shape requirements of the coil, such as 90°, 180°, or 360°.

[0043] Start the bending equipment and slowly and evenly bend the composite profile. During the bending process, closely monitor the deformation of the profile to ensure that there is no excessive deformation, cracking, or wrinkling at the bending point. Because the copper tube portion of the copper tube-steel strip composite profile has good ductility, but the steel strip portion is relatively hard, it is necessary to reasonably control the bending speed and force to avoid damage to the copper tube at the bending point due to the restriction of the steel strip.

[0044] For some complex-shaped heat sink coils, such as spiral coils, it may be necessary to perform bending operations multiple times. After each bending, the position and angle of the profile should be adjusted to gradually complete the formation of the entire coil. During the bending process, auxiliary tools, such as bending dies or guide devices, can be used to ensure the shape accuracy of the coil.

[0045] 2. Coil connection and fixing If the heatsink coil needs to be constructed from multiple sections of composite profiles, a connection process is required after bending and shaping. Welding can be used for this connection. For the copper sections, copper welding rods can be used to ensure a strong and airtight weld, preventing leakage of the heat dissipation medium. During welding, the welding temperature and time must be carefully controlled to avoid overheating, which could alter the internal structure of the copper tube and affect its thermal conductivity.

[0046] For the steel strip, riveting or bolting can be used for connection. If riveting is used, ensure that the riveting points are firm and reliable and will not loosen during use; if bolting is used, select bolts of appropriate specifications and tighten them to the specified torque to ensure connection strength.

[0047] After the coil is connected, it can be fixed at appropriate locations to enhance its overall structural stability. For example, at bends or connections, specialized clamps or brackets can be used to secure the coil to the internal structure of the radiator-type automotive packaging box, preventing damage from vibration or shaking during use.

[0048] 3. Coil performance testing After the heat dissipation coil is manufactured, its performance needs to be tested to ensure that it meets the heat dissipation requirements. The first step is to test its sealing performance, which can be done using air pressure or water pressure testing. Seal both ends of the coil and fill it with a certain pressure of gas (such as air) or liquid (such as water). Observe whether the pressure remains stable. If the pressure does not drop significantly within a specified time, the coil is considered to have good sealing performance; otherwise, there is a leakage problem, requiring repair or remanufacturing.

[0049] Next, thermal conductivity testing is performed. A thermal conductivity meter can be used to measure the thermal conductivity of the coil to ensure that its thermal conductivity meets design standards. Simultaneously, a simulated real-world environment can be used to test the coil's heat dissipation effect. For example, under certain temperature conditions, a certain flow rate of a heat dissipation medium (such as coolant) is introduced into the coil, and the temperature distribution and heat dissipation efficiency on the coil surface are measured. Based on the test results, the coil can be optimized and adjusted.

[0050] The process of fabricating a heat-dissipating automotive packaging box using heat dissipation coils is as follows: 1. Packaging box structure design Based on the dimensions and heat dissipation requirements of key automotive components (such as engines and battery packs), design the overall structure of a heat-dissipating automotive packaging box. Determine the length, width, and height dimensions of the packaging box, as well as the layout of the internal space, to ensure that it can accommodate the key automotive components and leave suitable installation positions for the cooling coils.

[0051] The internal structure design of the packaging box should take into account the arrangement of the cooling coils. For example, for engine cooling, the cooling coils can be arranged around the engine to maximize their contact with the engine surface and enhance heat transfer efficiency; for battery pack cooling, the cooling coils can be installed at the bottom or side of the battery pack, and the heat generated by the battery pack can be carried away by the circulating cooling medium.

[0052] Meanwhile, the structural design of the packaging box should include inlet and outlet channels for the heat dissipation medium to connect with external cooling systems (such as radiators and water pumps) and enable the circulation of the heat dissipation medium. Furthermore, the sealing and protective performance of the packaging box must be considered to prevent external environmental factors, such as dust and moisture, from entering the box during transportation and damaging critical automotive components and cooling coils.

[0053] 2. Heatsink installation The prepared heat dissipation coils are installed inside the heat-dissipating car body according to the design requirements. During the welding and installation process, it is essential to ensure that the heat dissipation coils fit tightly against the inner or outer wall of the body to improve heat transfer efficiency.

[0054] When installing the heat exchange coils, ensure that the inlet and outlet directions of the heat dissipation medium correspond to the connections of the external cooling system to guarantee smooth flow of the heat dissipation medium into and out of the heat exchange coils. Simultaneously, precisely adjust the installation position of the heat exchange coils to ensure even distribution within the packaging box, preventing localized overheating or uneven heat dissipation.

[0055] 3. Overall assembly and sealing of the packaging box After the radiator coils are installed, the overall assembly of the radiator-type automotive packaging box is carried out. The various components of the packaging box (such as the box body, lid, and doors) are assembled according to the design requirements, using appropriate connection methods (such as bolt connections and welding) to ensure that the connections between the components are firm and reliable.

[0056] During assembly, care should be taken to protect the heat sink and its connections to prevent impact or damage. The packaging box should also be sealed with sealant or sealing strips at all connections to prevent leakage of the cooling medium and the entry of external environmental factors into the box.

[0057] 4. Packaging box performance testing and debugging After the heat-dissipating car body box is assembled, its performance needs to be tested and adjusted. First, a sealing test is performed, similar to the sealing test of the radiator coil. Gas or liquid at a certain pressure is injected into the box to check for leaks. If a leak is found, the leak point must be located and repaired promptly.

[0058] Next, heat dissipation performance testing is conducted. Key automotive components (such as simulated engine loads or battery pack simulation devices) are installed inside the packaging box, and the external cooling system is activated, allowing the heat dissipation medium to circulate within the cooling coils. Temperature sensors monitor the temperature changes of the key automotive components and the temperature distribution inside the packaging box. Based on the test results, the parameters of the cooling system (such as the flow rate and temperature of the heat dissipation medium) are adjusted to ensure that the heat-dissipating automotive packaging box can meet the heat dissipation requirements of the key automotive components and guarantee that their temperature remains stable within a safe range during transportation.

[0059] During performance testing and debugging, the protective performance of the packaging box must also be tested, such as through vibration and impact tests to simulate various working conditions during transportation and check whether the packaging box can effectively protect the critical components and cooling coils of the vehicle. Based on the test results, the structure of the packaging box is optimized and improved to enhance its reliability and stability.
