Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to an adjustable retractable device for heat exchange fins. Background Technology
[0002] Currently, heat exchanger fin folding devices are typically designed to adjust and control the shape of the fins during the fin production process to ensure they meet specific design requirements.
[0003] However, the existing gathering devices have the following technical problems:
[0004] 1. Inability to independently adjust channels leads to poor fin consistency:
[0005] In existing technologies, heat exchanger finned devices typically lack the ability to independently adjust each channel. This means that when faced with manufacturing or assembly errors, it is difficult to ensure that the fin height and tilt angle within each channel are consistent, leading to inconsistent fin peak heights or tilting issues, which affects the overall quality consistency of the product.
[0006] 2. The requirements for machining and assembly precision are too high:
[0007] Under current technology, ensuring the consistency and pass rate of fins often requires very high precision in component processing and strict control of the assembly process. This high standard not only increases production costs but also makes the production line inflexible and difficult to adapt to various uncontrollable factors in the field environment, such as dust, further exacerbating the impact of installation errors.
[0008] 3. Debugging is complex and time-consuming:
[0009] Traditional debugging methods often rely on experienced technicians to make gradual adjustments by adding shims and other methods. This approach is time-consuming and labor-intensive, and requires a high level of technical skill from the operators. This directly leads to longer debugging times, increased costs for training new employees, and higher labor costs, while also reducing production efficiency and product delivery speed.
[0010] Therefore, there is a need for an adjustable retraction device for heat exchange fins that can solve the above problems. Utility Model Content
[0011] The purpose of this invention is to provide an adjustable folding device for heat exchange fins. This invention achieves separate control of the angles of folding fins A and B by setting two independently rotatable eccentric shafts (eccentric shaft A and eccentric shaft B). It can finely adjust the height and tilt of the fins to meet the requirements. This design can effectively solve the problem of minor fin variations caused by manufacturing or assembly errors, ensure the consistency of fin forming in each channel, and significantly improve the quality consistency of the product.
[0012] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an adjustable folding device for heat exchange fins, including a support base, an eccentric shaft bracket, an adjusting eccentric shaft, a folding plate A and a folding plate B.

[0014] The adjusting eccentric shaft includes eccentric shaft A and eccentric shaft B. One end of eccentric shaft A is rotatably connected to support plate B. The other end of eccentric shaft A passes through gathering piece B and gathering piece A and is connected to support plate A. Gathering piece B and eccentric shaft A are fixedly connected to each other.
[0015] One end of the eccentric shaft B is rotatably connected to the support plate B, and the other end of the eccentric shaft B passes through the gathering piece B and the gathering piece A and is connected to the support plate A. The gathering piece A and the eccentric shaft B are fixedly connected to each other.
[0016] Furthermore, finned baffle spacers are fixedly connected to the outer sides of both the gathering piece A and the gathering piece B.
[0017] Furthermore, both gathering piece A and gathering piece B are mounted on the connecting shaft, and gathering piece A and gathering piece B are rotatably connected to the connecting shaft.
[0018] Furthermore, an eccentric shaft locking block is provided on the outer side wall of the support plate A. The eccentric shaft locking block is fixed to the support plate A by bolts.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] Example 1:
[0034] Figure 1 This is a three-dimensional structural diagram of the present invention. Figure 2 for Figure 1 A schematic diagram of the internal structure, such as Figure 1 and Figure 2 The adjustable retractable device for heat exchange fins shown includes a support base 1, an eccentric shaft bracket, an adjusting eccentric shaft, retractable plates A6 and B7. The support base 1 is the basic structure of the entire retractable device, providing stable support for the eccentric shaft bracket, the adjusting eccentric shaft, and the retractable plates. By fixing all components to it, the stability and reliability of the entire device during operation are ensured.
[0035] The eccentric shaft bracket in this invention is fixedly connected to the support base 1. The eccentric shaft bracket includes support plate A2 and support plate B10, which form a robust frame. These supports not only the gathering pieces A6 and B7, but also provide mounting positions for the eccentric shafts A4 and B5. The design of the eccentric shaft bracket ensures that the gathering pieces A6 and B7 can rotate smoothly on the connecting shaft 11 and maintain their positions during adjustment. Support plate A2 and support plate B10 are interconnected via the connecting shaft 11, and the gathering pieces A6 and B7 are installed between support plate A2 and support plate B10.
[0036] The adjustable eccentric shaft includes eccentric shaft A4 and eccentric shaft B5. Eccentric shafts A4 and B5 are key components for achieving independent channel adjustment. One end of eccentric shaft A4 is rotatably connected to support plate B10, and the other end passes through gathering pieces B7 and A6 and is connected to support plate A2. Gathering piece A6 and eccentric shaft B5 are fixedly connected. The other end of eccentric shaft B5 passes through gathering pieces B7 and A6 and is connected to support plate A2. Gathering piece A6 and eccentric shaft B5 are fixedly connected. Gathering pieces A6 and B7 are both mounted on connecting shaft 11, and are rotatably connected to connecting shaft 11. Connecting shaft 11 connects support plate A2 and support plate B10 and also serves as the rotation center for gathering pieces A6 and B7. This ensures that gathering pieces A6 and B7 can rotate freely when needed while maintaining the stability of the overall structure. Figure 1 As shown, this invention features a grooved structure on one side of both the gathering plate A and the gathering plate B. The fins (not shown) rotate and pass through the grooved structures of the gathering plates A and B under the drive of the rotating shaft. When the eccentric shaft A4 or eccentric shaft B5 is rotated, due to its eccentricity, the position and angle of the gathering plate A6 or the gathering plate B7 can be changed, thereby adjusting the height and tilt angle of the fins. This design allows for independent control of the fin forming in each channel, improving product consistency.
[0037] This invention features fin retaining spacers 8 fixedly connected to the outer sides of both the gathering plates A6 and B7. The main function of the fin retaining spacers 8 is to prevent the fins from shifting their internal and external positions during the forming process, ensuring the accuracy and consistency of the fin forming. An eccentric shaft locking block 3 is provided on the outer wall of the support plate A2. The eccentric shaft locking block 3 is fixed to the support plate A2 by bolts. The eccentric shafts A4 and B5 are also locked to the support plate A2 by the eccentric shaft locking block 3. The eccentric shaft locking block 3 is used to lock the adjusted positions of the eccentric shafts A4 and B5. Once the fins are adjusted to the appropriate angle, the locking block locks the eccentric shafts A4 and B5, preventing them from loosening or moving.
[0038] Working principle and process description:
[0039] 1. Preparation stage
[0040] Installation device: Install the entire adjustable retractable device at the appropriate position on the heat exchanger fin production line, ensuring that the support base 1 is firmly fixed on the workbench.
[0041] Check the connections: Confirm that all components (including the eccentric shaft bracket, adjusting eccentric shaft, and retractable plates A6 and B7) are correctly installed and securely connected. Check that the connecting shaft 11 and the eccentric shaft can rotate freely.
[0042] 2. Initial Setup
[0043] Adjust the initial angle: According to production requirements, rotate eccentric shafts A4 and B5 to position the gathering plates A6 and B7 in the appropriate initial positions. Initial adjustments can be made manually or with tools.
[0044] Locking the initial position: Use the eccentric shaft locking block 3 to fix the eccentric shaft A4 and eccentric shaft B5 to the support plate A2 with bolts to ensure that they will not loosen during the commissioning process.
[0045] 3. Debugging Phase
[0046] If the fin height or tilt angle is found to be incorrect, loosen the eccentric shaft locking block 3.
[0047] Rotate eccentric shaft A4 or eccentric shaft B5 to fine-tune the angle of the condenser plate A6 or condenser plate B7. For example, if it is necessary to increase the height of the fin, eccentric shaft A4 or eccentric shaft B5 can be rotated to slightly move the position of the condenser plate A6 or condenser plate B7.
[0048] Relock the eccentric shaft locking block 3 to ensure that the adjusted eccentric shaft position is fixed.
[0049] Repeated adjustments: Continue trial production and observation until the fins fully meet the design requirements. Trial production should be conducted after each adjustment to verify the effectiveness of the adjustment.
[0050] 4. Formal production
[0051] Final locking: After the fins have achieved the desired effect, reconfirm the positions of eccentric shafts A4 and B5, and lock them completely with eccentric shaft locking block 3.
[0052] Start mass production: Start the production line and begin mass production of fins.
[0053] Quality monitoring: During production, the quality of fin forming is checked regularly to ensure consistency. If any deviation is found, production is stopped immediately and necessary adjustments are made.
[0054] Through the above-described specific usage process, the adjustable folding device of this utility model can effectively control the forming quality and consistency of the fins, thereby improving production efficiency and product quality.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
