Description

Technical Field

[0001] The utility model relates to the technical field of fin leveling, in particular to a fin leveling machine. Background Art

[0002] Fins are usually added to the surface of the heat exchange device where heat transfer is required by adding a metal sheet with strong thermal conductivity to increase the heat transfer surface area of ​​the heat exchange device. They are a component mainly used to increase the heat transfer area. The plate-fin heat exchanger widely used in modern heat exchangers is usually composed of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between two adjacent baffles to form a sandwich, called a channel. Such sandwiches are stacked according to different fluid modes and brazed into a whole to form a plate bundle, which is the core of the plate-fin heat exchanger.

[0003] The function of fins is to increase the heat transfer area between the fluid and the tube wall by accelerating the flow of the fluid to improve the heat transfer efficiency. Under the same heat exchanger volume and heat exchange conditions, the use of fins can significantly increase the heat transfer area and improve the heat transfer efficiency. The material of the fin is generally made of aluminum alloy, copper alloy, stainless steel and other materials. Taking aluminum alloy as an example, it has good thermal conductivity and corrosion resistance, which can effectively increase the service life of the heat exchanger.

[0004] In the process of manufacturing fins, there are situations where the fins need to be leveled, especially for fine-toothed window-type fins. During the demolding process, there are tiny flanges on the edges of the fine teeth, and a leveling process needs to be added to flatten these flanges to ensure the qualified rate of the fins. In the traditional fin leveling process, the operator places the already formed and cut fins in the predetermined groove position, and level them with the upper leveling tool. The size of the groove matches the size of the fin. There are some defects in the traditional fin leveling process. On the one hand, the fins need to be cut before they can be leveled, which consumes a lot of manpower and time. On the other hand, for the leveling of different fins, the grooves need to be replaced. This process is more troublesome, resulting in low efficiency of fin leveling. Utility Model Content

[0037] Embodiment 1:

[0038] Reference Figure 1 To Attachment Figure 4 As shown, a fin leveling machine according to a preferred embodiment of the utility model is schematically shown. The fin leveling machine 1 is used to level a fin. When leveling the fin, there is no need to cut the fin into a predetermined size. The fin can be directly connected to the fin forming production line to level the fin online, thereby improving production efficiency.

[0039] Figure 1 1 is a front cross-sectional view of the fin leveling machine 1 according to the first preferred embodiment of the utility model. In this embodiment, the fin leveling machine 1 includes a main frame mechanism 10, a driving mechanism 20, a leveling mechanism 30 and a calibration mechanism 40. The driving mechanism 20 and the leveling mechanism 30 are installed inside the main frame mechanism 10. The calibration mechanism 40 is arranged on both sides of the main frame mechanism 10 to adjust and calibrate the leveling mechanism 30 to meet the size of the fin to be leveled. The driving mechanism 20 is used to drive the leveling mechanism 30 to level the fin.

[0040] The main frame mechanism 10 includes an upper main body 11, a lower main body 12 and a guide assembly 13, wherein the upper main body 11 is integrally connected to the upper part of the lower main body 12, and the leveling mechanism 30 and the calibration mechanism 40 are installed on the upper main body 11. The guide assembly 13 is longitudinally arranged on the upper main body 11 to provide support for the main frame mechanism 10 and guide for the leveling mechanism 30.

[0041] The guide assembly 13 includes a plurality of guide posts 131, a plurality of guide sleeves 132 and a plurality of return springs 133. The guide posts 131 are longitudinally arranged on the upper main body 11, and the guide sleeves 132 are arranged outside the guide posts 131. In this embodiment, the guide sleeves 132 include a fixed guide sleeve 1321 and a movable guide sleeve 1322. The fixed guide sleeve 1321 is fixed to the top of the guide post 131, and the movable guide sleeve 1322 is suitable for longitudinally sliding from the guide post 131. The return spring 133 is arranged outside the guide post 131 and below the movable guide sleeve 1322. Specifically, when the movable guide sleeve 1322 slides downward, it is suitable for compressing the return spring 133; when the movable guide sleeve 1322 slides upward, the return spring 133 rebounds. It can reduce the force on the guide post 131, avoid damage to the fin leveler 1, and improve the service life of the fin leveler 1.

[0042] In this embodiment, the number of the guide column 131, the fixed guide sleeve 1321, the movable guide sleeve 1322 and the return spring 133 are all set to four, the guide column 131 is distributed in a matrix on the upper main body 11, and the fixed guide sleeve 1321, the movable guide sleeve 1322 and the return spring 133 are all arranged on the guide column 131.

[0043] The leveling mechanism 30 includes an upper leveling plate 31, a lower leveling plate 32, a fixed base 33 and a movable base 34, wherein the upper leveling plate 31 is mounted on the fixed base 33, and the lower leveling plate 32 is mounted on the movable base 34. In this embodiment, the upper leveling plate 31 is configured as a fixed plate, and the lower leveling plate 32 is configured as a movable plate, and the fin is suitable for performing a leveling process between the upper leveling plate 31 and the lower leveling plate 32. Specifically, the movable base 34 is driven by the driving mechanism 20 to slide longitudinally, thereby driving the lower leveling plate 32 to slide longitudinally, so that the fin performs a leveling process between the upper leveling plate 31 and the lower leveling plate 32.

[0044] Specifically, the fixed base 33 is connected to the fixed guide sleeve 1321, and the movable base 34 is connected to the movable guide sleeve 1322. Specifically, the movable guide sleeve 1322 is suitable for driving the movable base 34 to slide up and down from the guide column 131, thereby driving the lower leveling plate 32 to slide up and down from the guide column 131 to level the fins.

[0045] The driving mechanism 20 includes a driving motor 21, a driving belt 22, a driving spindle 23 and a driving support 24. The driving motor 21 is installed on the lower main body 12 of the main frame mechanism 10, and the driving spindle 23 is installed on the upper main body 11. The two ends of the driving belt 22 are respectively connected to the driving motor 21 and the driving spindle 23. One end of the driving support 24 is connected to the driving spindle 23, and the other end is supported on the movable base 34. In other words, the driving motor 21 is suitable for driving the driving spindle 23 through the driving belt 22, and the driving spindle 23 drives the driving support 24 to slide up and down, thereby controlling the movable base 34 and the lower leveling plate 32 to slide longitudinally from the guide column 131 to level the fins.

[0046] Figure 4 It is a partially enlarged schematic diagram of a fin leveling machine according to the first preferred embodiment of the utility model. The calibration mechanism 40 includes a calibration plate 41 and a wing height pad 42, and the calibration plate 41 and the wing height pad 42 are suitable for being installed on both sides of the upper main body 11 to adjust and calibrate the fin leveling machine 1. Specifically, the calibration plate 41 is used to calibrate the leveling mechanism 30 to improve the accuracy when leveling the fins. The thickness of the wing height pad 42 is consistent with the height of the fins to be leveled. By replacing different models of the wing height pad 42, fins of different sizes can be leveled.

[0047] In particular, the calibration plate 41 is used to adjust the parallelism and size of the upper screed plate 31. Specifically, the upper screed plate 31 may have a size error, which causes the upper screed plate 31 to be unable to be parallel to the lower screed plate 32, that is, the height of the left side and the height of the right side of the upper screed plate 31 are not flat. For example, when the height of the left side of the upper screed plate 31 is higher than the height of the right side, a calibration plate 41 with a smaller thickness is installed on the left side of the upper screed plate 31, and a calibration plate 42 with a larger thickness is installed on the right side, thereby ensuring that the upper screed plate 31 is in a plane and parallel to the lower screed plate 32. When the height of the left side of the upper screed plate 31 is lower than the height of the right side, a calibration plate 41 with a larger thickness is installed on the left side of the upper screed plate 31, and a calibration plate 42 with a smaller thickness is installed on the right side, thereby ensuring that the upper screed plate 31 is in a plane and parallel to the lower screed plate 32.

[0048] In addition, after adjusting the upper leveling plate 31 and the lower leveling plate 32 to be parallel, it is necessary to install the wing height pad 42 above the calibration plate 31, and the thickness of the wing height pad 42 is consistent with the thickness of the fin that needs to be leveled. Specifically, before installing the wing height pad 42, the lower leveling plate 32 needs to be moved to overlap with the upper leveling plate 31. That is, the upper plane of the lower leveling plate 32 and the lower plane of the upper leveling plate 31 fit each other. Then install the wing height pad 42. After installing the wing height pad 42, the position of the upper leveling plate 31 is suitable for translating the height of the wing height pad 42 upward on the original basis, so that the distance between the lower leveling plate 32 and the upper leveling plate 31 is consistent with the thickness of the wing height pad 42. Based on this, when the fin enters the fin leveling machine 1 for leveling, the fin can be accurately leveled.

[0049] Figure 2 It is a side sectional view of a fin leveling machine according to the first preferred embodiment of the utility model. In addition, the main frame mechanism 10 also includes a fin support 14, and the fin support 14 is arranged on the upper main body 11. Specifically, the fin support 14 is arranged on the front and rear sides of the upper main body 11, and the height of the plane where the top end of the fin support 14 is located is greater than the area where the gap between the upper leveling plate 31 and the lower leveling plate 32 is located. When the fin enters between the upper leveling plate 31 and the lower leveling plate 32 for leveling, the two ends of the fin are suitable for being supported by the fin support 14, so as to maintain the stability of the fin and better perform the leveling process. In other words, the fin is supported and placed in a curved shape during the leveling process.

[0050] The main frame mechanism 10 further includes a hanging portion 15 and a plurality of lower feet 16, wherein the hanging portion 15 is disposed at the top of the upper main body 11, and the lower feet 16 are disposed at the bottom of the lower main body 12, and the lower feet 16 are adapted to provide support. For example, an operator may use a crane to hang the hanging portion 15, and then move the position of the fin leveler 1. In other words, an operator may move the fin leveler 1 through the hanging portion 15 or the lower feet 16, so that the fin leveler 1 is placed at an accurate position of the production line, and the fins are leveled.

[0051] The main frame mechanism 10 also includes a reinforcing rib 17, which is disposed in the lower main body portion 12. Specifically, the reinforcing rib 17 is disposed at the connection between the upper main body portion 11 and the lower main body portion 12. The reinforcing rib 17 greatly increases the overall strength of the fin leveling machine 1.

[0052] Compared with the traditional fin leveling process, the fins need to be pre-cut and then leveled by the upper leveling plate. The process is complicated and consumes a lot of manpower and time. When the fin leveling machine 1 is leveling the fins, there is no need to cut the fins into a predetermined size. The fin leveling machine 1 can directly level the fins on the production line to improve production efficiency. In addition, the calibration plate 41 is used to calibrate the leveling mechanism 30 to improve the accuracy of the fin leveling process. The thickness of the wing height pad 42 is consistent with the height of the fins that need to be leveled. By replacing different models of the wing height pad 42, fins of different sizes can be leveled to improve the accuracy of the fin leveling process.

[0053] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
