Description

Technical Field

[0001] The invention relates to the technical field of heat exchanger production equipment, and specifically relates to a heat exchanger fin stacking device. Background Art

[0002] The finned heat exchanger is the most widely used heat exchange equipment for gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to ordinary base tubes. During the processing of the finned heat exchanger, the fins need to be welded to the heat pipes for assembly. Therefore, the equipment needs to be used to align the stacked fins of the heat exchanger before the subsequent fin installation work is carried out. In actual production, since the installation gaps of the heat exchanger fins are different in different heat exchangers, it is necessary to pre-adjust the spacing of several heat exchanger fins before welding the heat exchanger fins.

[0003] The Chinese patent document with publication number CN221781339U discloses a radiator fin mounting structure, in which the support groove can be used to mount the radiator fin. When the device is in use, the rotating block can be turned by a wrench to drive the fixing rod 1 and the threaded rod to rotate together, thereby changing the length of the fixing rod 1 entering the support box, thereby driving the connection plate to move, changing the distance between adjacent spirals of the spiral blade, and finally changing the distance between adjacent support grooves.

[0004] The disadvantage of this device is that, in the process of changing the distance between adjacent support grooves, the fixed rod 1 and the threaded rod must move in the horizontal direction to enter or extend out of the support box. This means that when the device is in use, additional space must be reserved in the length extension direction of the support box to prevent the fixed rod 1 or the threaded rod from colliding with other objects outside the support box after moving and changing positions. In other words, this device has the disadvantage of wasting floor space. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] See also Figure 1-18The present invention provides a technical solution: a stacking device for heat exchanger fins, comprising an assembly box 1, a spacing adjustment component 2, an elastic spiral blade 3 and a plurality of fin placement components 4. The spacing adjustment component 2 is arranged inside the assembly box 1, and the spacing adjustment component 2 comprises a support rod 21 and two control components 22. The elastic spiral blade 3 is sleeved on the middle part of the support rod 21. The plurality of fin placement components 4 are all arranged above the assembly box 1 and are all connected to the elastic spiral blade 3. A plurality of heat exchanger fins to be installed can be placed on the plurality of fin placement components 4 respectively to complete the stacking operation of the heat exchanger fins. The two control components 22 can make the elastic spiral blade 3 change its shape to stretch or shorten to adapt to the installation gap of different heat exchanger fins. When the elastic spiral blade 3 stretches, the spacing between adjacent fin placement components 4 becomes larger. When the elastic spiral blade 3 shortens, the spacing between adjacent fin placement components 4 becomes smaller. A clamping component 6 is provided on the top of the assembly box 1, and the clamping component 6 comprises two clamping plates 61 and two bidirectional electric telescopic rods 62. After the heat exchanger fins are placed on the fin placement assembly 4, the two bidirectional electric telescopic rods 62 are shortened to drive the two clamping plates 61 closer to each other, and a number of heat exchanger fins are pushed and aligned by the two clamping plates 61, and then welding and other installation operations are performed.

[0042] See also Figure 1-4 , Figure 6-11 The control assembly 22 includes a driving disk 221, a driving plate 222, a threaded rod 223 and a rotating block 224. A threaded hole 2221 is provided in the middle of the driving plate 222. The threaded rod 223 is screwed into the threaded hole 2221. The rotating block 224 is arranged on the outside of the assembly box 1. When the spacing between adjacent fin placement assemblies 4 needs to be changed, the rotating block 224 is screwed with a wrench, and the rotating block 224 drives the threaded rod 223 to rotate, and the threaded rod 223 drives the driving plate 222 to slide along the adjustment groove 211 at the end of the support rod 21 in the horizontal direction. The driving plate 222 drives the driving disk 221 to slide along the outer surface of the support rod 21, and the driving disk 221 changes the shape of the elastic spiral blade 3. When the rotating block 224 rotates forward, the elastic spiral blade 3 is extended, and the spacing between adjacent fin placement assemblies 4 becomes larger. When the rotating block 224 is reversed, the elastic spiral blade 3 is shortened, and the spacing between adjacent fin placement assemblies 4 becomes smaller. Since the present invention includes two control components 22, whether only one rotating block 224 is turned or both rotating blocks 224 are turned at the same time, the shape of the elastic spiral blade 3 can be changed. The control components 22 on both sides can also be used alternately to extend the service life of the control components 22.

[0043] See also Figure 1 , Figure 3 and Figure 6-11The fin placement assembly 4 includes an insertion rod 41 and a placement seat 42. The placement seat 42 is fixedly connected to the elastic spiral blade 3 through the insertion rod 41. The insertion rod 41 is arranged in the avoidance groove 11 on the top surface of the assembly box 1. The heat exchanger fins to be installed are placed on the placement seat 42. When the spacing between adjacent fin placement assemblies 4 changes, the insertion rod 41 slides along the avoidance groove 11. The avoidance groove 11 can limit the insertion rod 41 from shaking back and forth, ensuring the stability of the insertion rod 41 during movement.

[0044] See also Figure 1-3 , Figure 6 and Figure 17-18 , the rotating block 224 is fitted with the outer wall of the assembly box 1, and the two bidirectional electric telescopic rods 62 are respectively arranged in the two assembly grooves 16 at both ends of the top surface of the assembly box 1. A convex plate 611 is provided on the side wall of the clamping plate 61, and the convex plate 611 extends into the assembly groove 16, and the output end of the bidirectional electric telescopic rod 62 is fixedly connected to the convex plate 611. The width of the assembly groove 16 is greater than the width of the convex plate 611, and the depth of the assembly groove 16 is greater than the height of the bidirectional electric telescopic rod 62. The end face of the clamping plate 61 is flush with the side wall of the assembly box 1. Therefore, the wrench can be quickly aligned with the rotating block 224, saving the operation steps and operation time of the control component 22, and the wrench will not collide with the clamping plate 61 or the bidirectional electric telescopic rod 62 in the process of driving the rotating block 224 to rotate. When the present invention is in use, during the rotation of the rotating block 224, the rotating block 224 and the threaded rod 223 will not move in the horizontal direction and will not collide with other objects outside the support box. Therefore, there is no need to reserve additional space in the length extension direction of the assembly box, saving floor space.

[0045] Embodiment 2

[0046] Based on Example 1, please refer to Figure 1-4 and Fig.12 The present invention also includes a spacing reading component 5. During the process of adjusting the spacing between a plurality of heat exchanger fins, the user can observe the length of the spacing between adjacent fin placement components 4 in real time through the spacing reading component 5, and the user can quickly determine whether the spacing has been changed to a suitable position.

[0047] See also Figure 1-4 and Figure 12-14, the spacing reading assembly 5 includes a first indicator 51 and a second indicator 52, and the first indicator 51 and the second indicator 52 are both detachably connected to any plug rod 41. The first indicator 51 includes a first scale 511, and the second indicator 52 includes a first counting pointer 521. When the heat exchanger fin is placed on the placement seat 42 and before the elastic spiral blade 3 has not changed its shape, the first indicator 51 and the second indicator 52 are respectively installed in the middle of any two adjacent plug rods 41. Then use a wrench to twist the rotating block 224 to drive the elastic spiral blade 3 to extend or shorten. The operator observes the number on the surface of the first scale 511 pointed to by the first counting pointer 521 with his eyes. The distance between the first scale 511 and the first counting pointer 521 is the distance between the two adjacent plug rods 41 at present, and is also the distance between the two adjacent heat exchanger fins. When the number pointed to by the first counting pointer 521 is the same as the predetermined distance, the rotation of the rotating block 224 is stopped immediately, and the distance between the adjacent fin placement components 4 is adjusted and changed.

[0048] See also Fig.11 and Figure 13-14 The first indicator 51 also includes a first clamping plate 512, and the second indicator 52 also includes a second clamping plate 522. The first scale 511 is fixedly connected to the first clamping plate 512, and the first counting pointer 521 is fixedly connected to the second clamping plate 522. The first clamping plate 512 and the second clamping plate 522 can stably connect the first indicator 51 and the second indicator 52 to the insertion rod 41. When the insertion rod 41 moves, the first indicator 51 and the second indicator 52 will not fall off the insertion rod 41. The first clamping plate 512 is a U-shaped structure, and the side walls on both sides of the insertion rod 41 are provided with limiting grooves 411. The first clamping plate 512 can be quickly inserted by aligning the open end of the first clamping plate 512 with the limiting groove 411, and the limiting groove 411 can support the first clamping plate 512. A metal plate 43 is provided on the inner wall of the limiting groove 411, and a magnet 53 is provided on the inner wall of the first clamping plate 512. The magnet 53 can adsorb the metal plate 43 to prevent the first clamping plate 512 from sliding in the limiting groove 411. At this time, the first indicator 51 is installed. The structure of the second clamping plate 522 is the same as that of the first clamping plate 512, and the second indicator 52 can be installed in the same way.

[0049] See also Figure 1-7 and Figure 13-16The spacing reading component 5 also includes a first guide frame 54. The side wall of the assembly box 1 is provided with a first assembly opening 12 and a second assembly opening 13, and the second assembly opening 13 is located below the first assembly opening 12. The first clamping plate 512 and the second clamping plate 522 are both arranged in the first assembly opening 12, and the first guide frame 54 is arranged in the second assembly opening 13. A first guide groove 541 is arranged on the side wall of the first guide frame 54. When the first indicator 51 is installed, the first scale 511 is arranged in the first guide groove 541, and the first scale 511 can slide along the first guide groove 541, and the first guide groove 541 can provide support for the first scale 511. And because the first scale 511 is located outside the assembly box 1, it is also convenient to read.

[0050] See also Fig.11 and Figure 15-16 The spacing reading assembly 5 further includes a limit rod 55, both ends of which are fixedly connected to the inner wall of the assembly box 1, and a plug hole 412 is provided on the side wall of the plug rod 41, and the limit rod 55 is arranged in the plug hole 412. During the movement of the plug rod 41, the plug rod 41 can slide along the outer surface of the limit rod 55, and the limit rod 55 can limit the plug rod 41 from shaking left and right, thereby ensuring the stability of the plug rod 41 during the movement.

[0051] See also Figure 6-7 and Figure 12-14 , a slide groove 15 is provided on the inner side wall of the assembly box 1, and a force-bearing rod 58 is fixedly provided on the end surface of the first clamping plate 512 and the second clamping plate 522 facing the slide groove 15. When the magnet 53 adsorbs the metal plate 43, the force-bearing rod 58 just extends into the slide groove 15, and the force-bearing rod 58 can slide along the slide groove 15, and the slide groove 15 can provide support for the force-bearing rod 58. Therefore, when the insertion rod 41 drives the first clamping plate 512 or the second clamping plate 522 to move, the insertion rod 41 applies a thrust to the middle part of the first clamping plate 512 and the second clamping plate 522, ensuring that the first clamping plate 512 and the second clamping plate 522 are evenly stressed, and the first clamping plate 512 and the second clamping plate 522 can stably move in the horizontal direction.

[0052] Embodiment 3

[0053] Based on Example 2, please refer to Figure 1-5 and Figure 12-16 Several spacing reading components 5 can be installed, and the user can also judge whether the elastic spiral blade 3 has been aged or damaged by the cooperation of several spacing reading components 5, thereby further improving the accuracy of the present invention.

[0054] See also Figure 1-5In this embodiment, three spacing reading components 5 are provided. In the leftmost and rightmost spacing reading components 5, the first clamping plate 512 and the second clamping plate 522 are respectively installed on two adjacent plug rods 41. However, in the middle spacing reading component 5, there is an insertion rod 41 between the two plug rods 41 connected to the first clamping plate 512 and the second clamping plate 522. Next, read the values ​​on the first indicators 51 at the three positions. If the values ​​on the first indicators 51 at the two edges are the same, and the value on the first indicator 51 in the middle is exactly twice the value on the first indicator 51 at the edge position, it proves that the elastic spiral blade 3 has not aged at these three positions. If the values ​​on the first indicators 51 at the two edges are different, or the value on the first indicator 51 in the middle is not twice the value on the first indicator 51 at the edge position, it proves that the elastic spiral blade 3 has aged at one or several positions, and the elastic spiral blade 3 should be replaced. Furthermore, since the spacing reading assembly 5 can be installed on the insertion rod 41 at any position, the aging degree of any position of the elastic spiral blade 3 can be detected.

[0055] See also Figure 1-7 , Fig.12 and Figure 15-16 The spacing reading assembly 5 further includes a second guide frame 56. A third assembly opening 14 is provided below the second assembly opening 13. The second guide frame 56 is disposed in the third assembly opening 14 and is fixedly connected to the assembly box 1. A second guide groove 561 is provided on the side wall of the second guide frame 56. A second scale 57 is provided in the second guide groove 561. The first indicator 51 further includes a second counting pointer 513. The first clamping plate 512 and the first scale 511 are both fixedly connected to the second counting pointer 513. The second indicator 52 further includes a third counting pointer 523. The third counting pointer 523 is disposed directly below the first counting pointer 521. The third counting pointer 523 is connected to a clamping block 525 through a quick release rod 524. A clamping groove 5211 is provided on the side wall of the first counting pointer 521. The clamping block 525 is disposed in the clamping groove 5211.

[0056] See also Figure 1-5 and Figure 12-16, the length of the second scale 57 is greater than the distance between the two fin placement components 4 that are farthest apart, and the distance between the two fin placement components 4 that are farthest apart can be directly measured by the second scale 57. A spacing reading component 5 is installed on the leftmost and rightmost sides respectively. After the spacing between the plurality of fin placement components 4 is adjusted and changed, the third counting pointer 523, the quick release rod 524 and the clamping block 525 are installed on the third counting pointer 523 on the rightmost side. The second scale 57 is moved to slide in the second guide groove 561 so that the second counting pointer 513 is aligned with the zero mark of the second scale 57. Then the value of the distance between the two fin placement components 4 that are farthest apart is read out by the third counting pointer 523. Then read out the value on any one of the first scales 511 to check whether the value of the second scale 57 is an integer multiple of the value on the first scale 511.
