Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchange fin collection and pressing device. Background Technology

[0002] As a core component of heat exchange systems, heat exchangers are widely used in air conditioning and other equipment. The assembly of flat tubes and heat exchange fins is a crucial step in heat exchanger production. This requires precisely fitting and pressing multiple layers of fins onto multiple parallel flat tubes to form a dense heat exchange channel. Currently, the assembly of heat exchange fins and flat tubes mainly falls into two categories: manual assembly and semi-automated assembly. Manual assembly relies on operators manually fitting the fins into the flat tubes or pressing them together using simple tools. This not only involves high labor intensity and low production efficiency but also makes it difficult to control assembly accuracy. Semi-automated assembly... Automated equipment requires manual placement of flat tubes onto positioning fixtures before equipment presses fins onto them. For example, the patent background technology with application number CN201620397114.9 mentions that fin flattening also requires manual operation, that is, fixing the finned tube with clamps and then pressing it with heavy iron blocks to flatten the fins. This pressing method lacks positioning processing for the flat tube and fins, and cannot guarantee the fitting accuracy between the flat tube and fins before pressing. Therefore, there is an urgent need for a heat exchange fin collection and pressing device to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a heat exchange fin collection and pressing device to solve the problem of pressing fins onto flat tubes in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution: A heat exchange fin collection and pressing device includes: A pressing frame is provided with a pressing module, a flat tube feeding module and a fin feeding module. The pressing module presses the fins fed from the fin feeding module onto the flat tubes fed from the flat tube feeding module. The pressing module includes a riveting frame mounted on the pressing machine frame, and a flat tube base mounted on the pressing machine frame below the riveting frame. The riveting machine frame is equipped with a liftable riveting base plate. A fin clamping plate for holding fins is provided on the lower side of the riveting base plate. The flat tube base is slidably connected to the pressing machine frame along the feeding direction parallel to the flat tube feeding assembly. Multiple sets of liftable limiting plates are provided on the lower side of the flat tube base. Each set of limiting plates is equipped with multiple sets of limiting rods. The spacing between adjacent limiting rods along the sliding direction of the flat tube base matches the thickness of a single flat tube. The multiple sets of limiting plates are equally distributed along the sliding direction perpendicular to the flat tube base.

[0005] To achieve the above technical solution, a pressing module is used to press the fins from the fin feeding module onto the flat tubes from the flat tube feeding module. This makes the fin and flat tube conveying mechanisms independent, improving conveying stability. When pressing the fins onto the flat tubes, the flat tube feeding module first conveys the flat tubes to the flat tube base. At this time, the limiting plate is raised, allowing the limiting rods to extend beyond the upper side of the flat tube base. The flat tube conveying assembly then sequentially conveys the flat tubes between adjacent limiting rods, ensuring uniform spacing between adjacent flat tubes. Multiple sets of limiting plates are evenly distributed along the sliding direction perpendicular to the flat tube base, providing limiting rods along the length of the flat tubes. This further ensures the support stability of each set of flat tubes on the flat tube base, facilitating the subsequent assembly of the fins directly onto the flat tubes after the fin clamping plate holds the fins.

[0006] In one embodiment of the present invention, the flat tube feeding module includes a feeding rack, a feeding plate is provided on the feeding rack near the riveting machine frame, a flat tube limiting plate is provided on the feeding rack near the feeding plate, the distance between the flat tube limiting plate and the feeding plate is the thickness of one flat tube, and a liftable flat tube pressing plate is also provided on the feeding rack for pressing the flat tube from the gap between the flat tube limiting plate and the feeding plate onto the flat tube base.

[0007] To achieve the above technical solution, the distance between the flat tube limiting plate and the feeding plate is the thickness of one flat tube. This ensures that each time the flat tube pressing plate is pressed into the flat tube base below the feeding frame, a set of flat tubes is formed. This guarantees the assembly stability of the flat tubes on the flat tube base. The flat tube base slides parallel to the feeding direction of the flat tube feeding assembly, so that a set of flat tubes can be placed between each adjacent limiting rod, thus ensuring the stability of the subsequent fin assembly.

[0008] In one embodiment of this utility model, a base slide rail is provided on the press frame, the base slide rail extends to the lower side of the loading frame, the flat tube base is slidably engaged with the base slide rail, a flat tube screw is provided on the lower side of the flat tube base, and the flat tube base and the flat tube screw are threadedly connected. When it is necessary to assemble the flat tube onto the flat tube base, the flat tube base slides to the lower side of the loading frame.

[0009] To achieve the above technical solution, when assembling the flat tube onto the flat tube base, the flat tube base first slides along the base slide rail to the lower side of the press frame, so that the front end of the flat tube base is flush with the feeding plate. Each time a set of flat tubes is assembled, the flat tube screw drives the flat tube base to move towards the riveting frame, thereby filling the flat tube base with flat tubes, which facilitates the subsequent assembly of fins.

[0010] In one embodiment of the present invention, two sets of fin clamping plates are symmetrically arranged on the lower side of the riveting base plate, a clamping plate driving member is arranged on the upper side of the riveting base plate, and clamping plate slide rails are arranged on both sides of the clamping plate driving member. The fin clamping plates are slidably connected to the clamping plate slide rails, and the clamping plate driving member drives the two sets of fin clamping plates to move in opposite directions to clamp the fins.

[0011] To achieve the above technical solution, the clamping plate drive unit drives two sets of fin clamping plates to move in opposite directions along the clamping plate slide rail, thereby enabling the clamping and processing of fins. The clamping plate slide rail can guide the movement of the fin clamping plates, thereby ensuring the stability of the fin clamping process.

[0012] In one embodiment of the present invention, a clamping plate groove is provided on the riveting base plate, a slider is provided between the fin clamping plate and the clamping plate slide rail, the slider is connected to the fin clamping plate through a clamping plate connecting seat, and the clamping plate connecting seat and the clamping plate groove are in sliding engagement.

[0013] To achieve the above technical solution, the clamping plate groove can provide a guiding function for the clamping plate connecting seat, and by placing the fin clamping plate on the lower side of the riveting base plate, it can be ensured that the clamping space of the fin is not disturbed by other mechanisms, thus ensuring the clamping stability of the fin.

[0014] In one embodiment of the present invention, the fin feeding assembly includes a fin feeding rack disposed on one side of the riveting frame on the pressing machine frame. The fin feeding rack is arranged along the feeding direction perpendicular to the flat tube feeding assembly. A fin moving frame is slidably connected to the fin feeding rack along the feeding direction perpendicular to the flat tube. The fin moving frame transports the fins to the underside of the riveting base plate in the riveting machine frame so that the fin clamping plate can clamp the fins on the fin moving frame.

[0015] In one embodiment of the present invention, a fin feeding rack is provided on the side of the fin feeding rack away from the riveting machine frame, for conveying fins to the fin feeding rack, and a fin pushing rack is provided on the fin feeding rack on the upper side of the fin moving frame, for pushing the fins to the side closer to the riveting machine frame.

[0016] To achieve the above technical solution, the fin feeder is responsible for conveying the fins to the fin moving frame, the fin pusher is used to push the fins to the side close to the riveting machine frame, and then the fin moving frame conveys the fins to the underside of the riveting base plate inside the riveting machine frame. The fin clamping plate can hold the fins on the fin moving frame.

[0017] In one embodiment of the present invention, a movable slide rail is provided on the fin feeding rack, and a movable slider is provided between the bottom of the fin moving frame and the movable slide rail. The movable slider and the movable slide rail are slidably engaged, and the movable slider is located on the side away from the riveting machine frame so that the front end of the fin moving frame can extend into the lower side of the riveting base plate.

[0018] To achieve the above technical solution, by setting the movable slider on the side away from the riveting machine frame, the front end of the fin moving frame can extend into the lower side of the riveting base plate when the fin moving frame slides on the movable slide rail, so that the fin clamping plate can hold the fins on the fin moving frame.

[0019] As described above, the heat exchange fin collection and pressing device of this utility model has the following beneficial effects: the pressing module presses the fins conveyed by the fin feeding module onto the flat tubes conveyed by the flat tube feeding module, so that the conveying mechanisms of the fins and the flat tubes are independent of each other, thereby improving the stability of the conveying.

[0020] When fins need to be pressed onto flat tubes, the flat tube feeding module first transports the flat tubes to the flat tube base. At this time, the limiting plate is raised so that the limiting rod can extend out of the upper side of the flat tube base. The flat tube conveying assembly transports the flat tubes sequentially between adjacent limiting rods, thereby ensuring that the spacing between adjacent flat tubes is uniform. Multiple sets of limiting plates are equally distributed along the sliding direction perpendicular to the flat tube base, which provides limiting rods arranged along the length of the flat tube, further ensuring the support stability of each set of flat tubes on the flat tube base, thus facilitating the subsequent assembly of the fins directly onto the flat tube after the fin clamping plate holds the fins.

[0033] Please see Figures 1 to 10This utility model provides a heat exchange fin collection and pressing device, including a pressing frame 1, a pressing module, a flat tube feeding module and a fin feeding module arranged on the pressing frame 1. The pressing module presses the fins conveyed by the fin feeding module onto the flat tubes conveyed by the flat tube feeding module. The pressing module includes a riveting frame 2 arranged on the pressing frame 1 and a flat tube base 3 arranged on the pressing frame 1 below the riveting frame 2.

[0034] The riveting frame 2 is equipped with a liftable riveting base plate 4. The lower side of the riveting base plate 4 is equipped with a fin clamping plate 5 for holding the fins. The flat tube base 3 is slidably connected to the pressing frame 1 along the feeding direction parallel to the flat tube feeding assembly. The lower side of the flat tube base 3 is equipped with multiple sets of liftable limiting plates 6. Each set of limiting plates 6 is equipped with multiple sets of limiting rods 7. Furthermore, the spacing between adjacent limiting rods 7 along the sliding direction of the flat tube base 3 matches the thickness of a single flat tube. The multiple sets of limiting plates 6 are equally distributed along the sliding direction perpendicular to the flat tube base 3.

[0035] The pressing module presses the fins from the fin feeding module onto the flat tubes from the flat tube feeding module, making the fin and flat tube feeding mechanisms independent of each other and improving the stability of the feeding process.

[0036] When it is necessary to press the fins onto the flat tube, the flat tube feeding module first transports the flat tube to the flat tube base 3. At that time, the limiting plate 6 is raised so that the limiting rod 7 can extend out of the upper side of the flat tube base 3. The flat tube conveying assembly transports the flat tubes sequentially between adjacent limiting rods 7, thereby ensuring that the spacing between adjacent flat tubes is uniform. The multiple sets of limiting plates 6 are equally distributed along the sliding direction perpendicular to the flat tube base 3, which can provide the flat tube with limiting rods 7 arranged along the length of the flat tube, further ensuring the support stability of each set of flat tubes on the flat tube base 3, thus facilitating the subsequent assembly of the fin clamping plate 5 directly onto the flat tube after clamping the fins.

[0037] The flat tube feeding module includes a feeding rack 8, a feeding plate 9 is provided on the feeding rack 8 near the riveting machine frame 2, a flat tube limiting plate 10 is provided on the feeding rack 8 near the feeding plate 9, the distance between the flat tube limiting plate 10 and the feeding plate 9 is the thickness of one flat tube, and a liftable flat tube pressing plate 11 is also provided on the feeding rack 8, which is used to press the flat tube from the gap between the flat tube limiting plate 10 and the feeding plate 9 onto the flat tube base 3.

[0038] By using the distance between the flat tube limiting plate 10 and the feeding plate 9 as the size of one flat tube thickness, the flat tube pressing plate 11 presses into the flat tube base 3 below the feeding rack 8 each time, thus ensuring the assembly stability of the flat tube on the flat tube base 3. The flat tube base 3 slides along the feeding direction parallel to the flat tube feeding assembly, so that a set of flat tubes can be placed between each adjacent limiting rod 7, thus ensuring the stability of the subsequent fin assembly.

[0039] The press frame 1 is equipped with a base slide rail 12, which extends to the lower side of the loading rack 8. The flat tube base 3 is slidably engaged with the base slide rail 12. A flat tube screw 13 is provided on the lower side of the flat tube base 3, and the flat tube base 3 and the flat tube screw 13 are threadedly connected. When it is necessary to assemble the flat tube onto the flat tube base 3, the flat tube base 3 slides to the lower side of the loading rack 8.

[0040] When assembling the flat tube onto the flat tube base 3, the flat tube base 3 first slides along the base slide rail 12 to the lower side of the press frame 1, so that the front end of the flat tube base 3 is flush with the feeding plate 9. Each time a set of flat tubes is assembled, the flat tube screw 13 drives the flat tube base 3 to move towards the riveting frame 2, thereby filling the flat tube base 3 with flat tubes, which facilitates the subsequent assembly of fins.

[0041] Two sets of fin clamping plates 5 are symmetrically arranged on the lower side of the riveting base plate 4. A clamping plate driving member 14 is arranged on the upper side of the riveting base plate 4. Clamping plate slide rails 15 are arranged on both sides of the clamping plate driving member 14. The fin clamping plates 5 are slidably connected to the clamping plate slide rails 15. The clamping plate driving member 14 drives the two sets of fin clamping plates 5 to move in opposite directions to clamp the fins.

[0042] The clamping drive 14 drives the two sets of fin clamping plates 5 to move in opposite directions along the clamping slide rail 15, thereby enabling the clamping and processing of the fins. The clamping slide rail 15 guides the movement of the fin clamping plates 5, thus ensuring the stability of the fin clamping plates 5 during the clamping process.

[0043] The base plate 4 is provided with a clamping plate groove 16. A slider 17 is provided between the fin clamping plate 5 and the clamping plate slide rail 15. The slider 17 and the fin clamping plate 5 are connected by a clamping plate connecting seat 18, and the clamping plate connecting seat 18 and the clamping plate groove 16 are in sliding fit.

[0044] The clamping groove 16 provides guidance for the clamping plate connecting seat 18, and the fin clamping plate 5 is set on the lower side of the riveting base plate 4, which can ensure that the clamping space of the fin is not disturbed by other mechanisms and ensure the clamping stability of the fin.

[0045] The fin feeding assembly includes a fin feeding rack 19 located on one side of the riveting frame 2 on the pressing frame 1. The fin feeding rack 19 is arranged perpendicular to the feeding direction of the flat tube feeding assembly. A fin moving frame 20 is slidably connected to the fin feeding rack 19 along the feeding direction perpendicular to the flat tube.

A fin pushing rack 22 is provided on the fin feeding rack 19 on the upper side of the fin moving frame 20, which is used to push the fins to the side closer to the riveting machine frame 2.

[0047] The fin feeder 21 is responsible for conveying fins to the fin moving frame 20. The fin pusher 22 is used to push the fins to the side close to the riveting machine frame 2. Then the fin moving frame 20 conveys the fins to the underside of the riveting base plate 4 inside the riveting machine frame 2. The fin clamping plate 5 can hold the fins on the fin moving frame 20.

[0048] A movable slide rail 23 is provided on the fin feeding rack 19. A movable slider 24 is provided between the bottom of the fin moving frame 20 and the movable slide rail 23.

The movable slider 24 is located on the side away from the riveting machine frame 2, so that the front end of the fin moving frame 20 can extend into the lower side of the riveting base plate 4.

[0049] By setting the movable slider 24 on the side away from the riveting machine frame 2, the front end of the fin movable frame 20 can extend into the lower side of the riveting base plate 4 when the fin movable frame 20 slides on the movable slide rail 23, so that the fin clamping plate 5 can clamp the fins on the fin movable frame 20.

[0050] This invention utilizes a pressing module to press the fins conveyed by the fin feeding module onto the flat tubes conveyed by the flat tube feeding module, making the fin and flat tube conveying mechanisms independent of each other and improving the stability of the conveying process.

[0051] When it is necessary to press the fins onto the flat tube, the flat tube feeding module first transports the flat tube to the flat tube base 3. At that time, the limiting plate 6 is raised so that the limiting rod 7 can extend out of the upper side of the flat tube base 3. The flat tube conveying assembly transports the flat tubes sequentially between adjacent limiting rods 7, thereby ensuring that the spacing between adjacent flat tubes is uniform. The multiple sets of limiting plates 6 are equally distributed along the sliding direction perpendicular to the flat tube base 3, which can provide the flat tube with limiting rods 7 arranged along the length of the flat tube, further ensuring the support stability of each set of flat tubes on the flat tube base 3, thus facilitating the subsequent assembly of the fin clamping plate 5 directly onto the flat tube after clamping the fins.
