Description

Technical Field

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

[0002] Heat exchanger fins are key components that significantly improve heat exchange efficiency by expanding the heat exchange surface and enhancing fluid turbulence. They are widely used in industries such as air conditioning, refrigeration, power, chemical and automotive.

[0003] A search revealed a heat exchanger fin processing device disclosed in publication number CN220678326U, comprising a fixed platform, heat exchanger fins, and a fixed frame. The fixed platform has a driving component inside, a connecting plate connected to the driving component, a support plate at the top of the connecting plate, a first fixed plate at the top of the support plate, two guide rods symmetrically arranged on one side of the support plate near its top, a guide slide plate between the guide rods, a second fixed plate at the top of the guide slide plate, a spray box at the top of the fixed platform, a movable box one located in the center of the top of the spray box, a connecting block at the bottom of the movable box one, a movable box two located at the bottom of the connecting block, and two spray plates symmetrically arranged on the movable box two.

[0004] The above-described technical solution has certain beneficial effects, but in actual use, the guide rod and the guide slide plate cannot be connected and fixed, causing the guide rod and the guide slide plate to deviate when the whole moves, thereby driving the second fixed plate to move. It cannot cooperate with the first fixed plate to stably support the heat exchanger fins. Therefore, we propose a heat exchanger fin processing device. Utility Model Content

[0014] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0015] As shown in Figure 1- Figure 5As shown, a heat exchanger fin processing device includes a base 1. A fixed guide groove 2 is provided in the middle of the top of the base 1. A servo motor 3 is fixedly connected to one end of the base 1. A threaded rod is fixedly connected to the output end of the servo motor 3. A movable clamp 4 is movably sleeved on the outer side of the threaded rod at the output end of the servo motor 3. A spray chamber 5 is fixedly provided on the top of the base 1. Fixed positioning feet 6 are symmetrically provided on the other end of the base 1. A transfer mechanism 7 is connected inside the fixed positioning feet 6. The movable clamp 4 includes a movable base 41. A connecting mounting bracket 42 is fixedly connected to the top of the movable base 41. A fixed connecting arm 43 is fixedly connected to the middle of the bottom of one side of the connecting mounting bracket 42. A fixed connecting plate 44 is fixedly connected to the other end of the fixed connecting arm 43. A fixed reinforcing arm 45 is fixedly connected between the bottom end of the fixed connecting arm 43 and the top of the movable base 41. A fixed guide arm 46 is fixedly connected between the connecting mounting bracket 42 and the end of the fixed connecting plate 44. A movable mounting sleeve 47 is movably sleeved on the outer surface of the movable mounting sleeve 47. A threaded connecting sleeve 48 is fixedly connected to one side of the movable mounting sleeve 47. A threaded connecting rod 49 is movably connected to the inner side of the threaded connecting sleeve 48 via threads. A rotating end plate 410 is fixedly connected to one end of the threaded connecting rod 49. A through hole adapted to the threaded connecting rod 49 is opened on the surface of the movable mounting sleeve 47. A connecting top block 411 is fixedly connected to the top of the movable mounting sleeve 47. A clamping mechanism 412 is fixedly connected to the top of the connecting top block 411.

[0016] The working principle of the above technical solution is as follows: During use, the moving clamp 4 clamps and fixes the heat exchanger fins. Simultaneously, under the action of the servo motor 3 and the threaded rod, the moving clamp 4 and the heat exchanger fins move towards the inside of the spraying chamber 5 to perform spraying processing on the surface of the heat exchanger fins. Then, the heat exchanger fins are removed and placed inside the transfer mechanism 7. When the inside of the transfer mechanism 7 is full, it is adjusted to disengage from the fixed positioning support 6, thus enabling rapid transfer of the heat exchanger fins. The operation is convenient and quick, facilitating the placement of the heat exchanger fins between the connecting mounting bracket 42 and the clamping mechanism 412. Next, the moving mounting sleeve 47 moves, causing the threaded connecting sleeve 48, threaded connecting rod 49, rotating end plate 410, connecting top block 411, and clamping mechanism 412 to move, allowing the clamping mechanism 412 to connect with the connecting mounting bracket 42. The heat exchanger fins are clamped between the two sides, and then the rotating end plate 410 is rotated, which drives the threaded connecting rod 49 to rotate, so that the threaded connecting rod 49 can resist each other with the fixed guide arm 46, thereby connecting and fixing, and stably clamping and fixing the heat exchanger fins. The operation is convenient.

[0017] In another embodiment, such as Figure 4 As shown, the clamping mechanism 412 includes a fixed sleeve block 4121. A force spring 4122 is fixedly connected to one end of the fixed sleeve block 4121. A connecting mounting plate 4123 is fixedly connected to the other end of the force spring 4122. A fixed connecting rod 4124 is fixedly connected to the middle of the side of the connecting mounting plate 4123 away from the force spring 4122. A connecting anti-slip clamp 4125 is fixedly connected to one end of the fixed connecting rod 4124 and one side of the connecting mounting bracket 42.

[0018] When the anti-slip clamp 4125 is in contact with the heat exchanger fins, it can push the fixed connecting rod 4124, which in turn moves the connecting mounting plate 4123, compressing the force spring 4122 for adjustment. This makes the operation convenient.

[0019] In another embodiment, such as Figure 4 As shown, a first handle 4126 is fixedly connected to the middle of the connecting anti-slip clamp 4125 located at the end of the fixed connecting rod 4124 on one side near the fixed connecting rod 4124. This allows the first handle 4126 to be pulled, moving the connecting anti-slip clamp 4125, thereby detaching the heat exchanger fins from the connecting anti-slip clamp 4125 and the connecting mounting bracket 42 for disassembly, making the operation convenient.

[0020] In another embodiment, such as Figure 5 As shown, the transfer mechanism 7 includes a connecting block 71, a connecting top plate 72 fixedly connected to the top of the connecting block 71, a fixed limiting frame 73 movably sleeved on the outer side of the end surface of the connecting top plate 72, a transfer box 76 fixedly connected to one side of the fixed limiting frame 73, a caster wheel 78 fixedly connected to the bottom end of the transfer box 76, a connecting top arm 74 fixedly connected to the top of the connecting top plate 72, and a second handle 75 fixedly connected to the middle of the top of the connecting top arm 74. This allows for easy pulling of the second handle 75, which moves the connecting top arm 74, the connecting top plate 72, and the connecting block 71, causing the connecting block 71 to disengage from the inner side of the fixed positioning leg 6. Under the action of the caster wheel 78, the heat exchanger fins can be transferred, making operation convenient.

[0021] In another embodiment, such as Figure 5 As shown, the outer surface of the connecting block 71 slides and engages with the interior of the fixed positioning leg 6. This allows the connecting block 71 to engage with the interior of the fixed positioning leg 6, thereby limiting the connection.

[0022] In another embodiment, such as Figure 5 As shown, a third handle 77 is fixedly connected to one side of the transfer box 76. This facilitates pushing and pulling the third handle 77, thereby enabling the transfer mechanism 7 and the heat exchanger fins to be transferred quickly, improving operational convenience.

[0023] The working principle of this utility model is as follows: During use, the heat exchanger fins are placed between the connecting anti-slip clamps 4125. Then, the movable mounting block 47 is moved, which drives the threaded connecting sleeve 48, threaded connecting rod 49, rotating end plate 410, connecting top block 411, and clamping mechanism 412 to move. When the connecting anti-slip clamps 4125 come into contact with the heat exchanger fins, the connecting anti-slip clamps 4125 can push the fixed connecting rod 4124, which drives the connecting mounting plate 4123 to move, compressing the force spring 4122. At this time, the heat exchanger fins are clamped. Then, the rotating end plate 410 is rotated, which drives the threaded connecting rod 49 to rotate, so that the threaded connecting rod 49 can resist each other with the fixed guide arm 46, thereby connecting and fixing, and stably clamping and fixing the heat exchanger fins. The servo motor 3 drives the threaded rod, so that the entire movable clamp 4 can move towards the spray chamber 5. The heat exchanger fins are sprayed on the inside of the spraying chamber 5. After the spraying is completed, the moving clamp 4 and the heat exchanger fins are disengaged from the inside of the spraying chamber 5. The first handle 4126 is pulled, which moves the connecting anti-slip clamp 4125. This allows the heat exchanger fins to be disengaged from the connecting anti-slip clamp 4125 and the connecting mounting bracket 42 for disassembly. The heat exchanger fins are then placed inside the transfer box 76. After the transfer box 76 has loaded the heat exchanger fins, the second handle 75 is pulled, which moves the connecting top arm 74, the connecting top plate 72, and the connecting locking block 71. This causes the connecting locking block 71 to disengage from the inside of the fixed positioning support 6. With the help of the caster wheel 78, the heat exchanger fins can be transferred. The overall structure is simple and the operation is convenient and quick.

[0024] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
