Description

Technical Field

[0001] This utility model relates to the field of radiator manufacturing technology, specifically to a winged flat tube bending and forming device. Background Technology

[0002] Finned tube heat exchangers use finned tubes as heat transfer elements, featuring small size, large heat transfer surface area, and high efficiency. Therefore, they are widely used in refrigeration and air conditioning systems. Research has confirmed that the contact thermal resistance between the fins and the flow channel of a finned tube heat pipe is a crucial factor limiting the improvement of heat dissipation performance. Flying fin flat tubes are manufactured through a continuous slicing process on the surface of aluminum alloy (or other machinable materials), with their heat dissipation fins directly formed on the outer wall of the fluid channel, thus achieving contactless thermal resistance in the heat conduction process. In recent years, flying fin flat tubes have found wide applications in air conditioning and refrigeration, automotive processes, heating systems, electronic equipment cooling, aerospace, and other fields.

[0003] With increasing demands for efficient heat dissipation, straight tube designs have shown limitations in some applications, especially in space-constrained situations or where maximizing heat exchange area is required. Flanged heat exchange tubes, formed by bending, can not only adapt to compact layouts but also significantly increase the surface area in contact with the fluid, thereby improving heat exchange efficiency. However, traditional bending processes easily lead to deformation, breakage, or even detachment of the finned tubes under pressure. Particularly when mechanical bending is used, localized stress concentration can cause irreversible plastic deformation of the finned tubes on both sides, severely impacting heat exchange efficiency and service life.

[0030] Example 1

[0031] A wing-shaped flat tube bending and forming device, wherein the two sides of the wing-shaped flat tube are alternately provided with smooth bending areas 52, such as... Figure 1 As shown, the flying wing flat tube bending and forming device includes Frame 1: includes machine base 11; Y-axis linear module 2: includes a base plate 21 and a first drive structure 22, with the base plate 21 slidably connected to the machine base 11; Rotating module 3 includes a clamping component 31, a positioning component 32, and a second driving structure 33. The clamping component 31 is used to clamp and release the protruding ribs 51 on the upper and lower sides of the wing tube. The positioning component 32 includes a spindle 321 and a third driving structure 322. The third driving structure 322 can drive the spindle 321 to be positioned and moved away in the bending area 52 of the wing tube. When the spindle 321 is positioned in the bending area 52 of the wing tube, the second driving structure 33 can drive the clamping component 31 to rotate at a preset angle and drive the wing tube to bend around the spindle 321 to form a bent part. The rotating module 3 is fixed on the base plate 21, and the first driving structure 22 can drive the base plate 21 to move the rotating module 3 along the Y-axis; the first horizontal axis is along the input direction of the flying wing flat tube, and the Y-axis is a second horizontal axis perpendicular to the first horizontal axis.

[0032] like Figure 2As shown, in this embodiment, the winged flat tube includes a flow channel and wings formed by shavings on the two wider sides of the flow channel. The two narrower sides of the flow channel (i.e., the upper and lower sides of the winged flat tube) are provided with raised ribs 51. The bending area 52 on the winged flat tube refers to the area on the side of the flow channel where no wings are provided. This area can be used to rotate and bend the entire winged flat tube around the cylindrical forming part, forming the inner side of the bent winged flat tube. The bending areas 52 are alternately provided on both sides of the winged flat tube (referring to the two wider sides of the flow channel), thereby providing relative bending portions 53 for the bending and forming of the winged flat tube, achieving continuous bending of the winged flat tube. It should be noted that because the wings formed by shavings on both sides of the winged flat tube are thin and densely arranged, for simplicity, the structure of a single wing is not shown in the figure.

[0033] It should be noted that this utility model is not limited to the method of setting the bending area 52 on the winged flat tube; the method of alternately removing the winged area on both sides of the flow channel is also acceptable.

[0034] When using the winged flat tube bending and forming device of this embodiment for bending operations, the bending of one side of the winged flat tube may include the following steps:

[0035] S1, input the wing flat tube, and under the drive of the third drive structure 322, the spindle 321 is positioned in a bending area 52 on one side of the wing flat tube, and the clamping assembly 31 clamps the protruding ribs 51 on the upper and lower sides of the wing flat tube; thereby achieving the fixation of the wing flat tube.

[0036] S2, under the drive of the second drive structure 33, the clamping component 31 is rotated at a preset angle, and the flying wing flat tube is bent around the spindle 321 to form a bent part 53; thereby realizing the bending of the flying wing flat tube around the bending area 52 at a preset angle, and the bent part 53 is the inner side of the bend.

[0037] S3, the clamping component releases the protruding ribs 51 on both sides of the wing tube, and the third drive structure 322 drives the spindle 321 to move away from the bent portion 53 of the wing tube to complete the bending. The bending of one side of the wing tube is completed through steps S1 and S2, and the gripping and releasing of the wing tube is performed through step S3.

[0038] S4, driven by the first drive structure 22, the rotating module 3 moves along the Y-axis, so that the spindle 321 can be positioned in the next bending area 52 of the flying wing flat tube.

[0039] S5, convey the wing flat tube to the next bending zone 52.

[0040] S6, then repeat operations S1~S5 to complete the bending and forming of the wing flat tube, and obtain the bent and formed wing flat tube.

[0041] Understandably, during the actual bending and forming operation, the position of the bent portion 53 and the next area to be bent 52 relative to the flow channel of the flying wing flat tube can be adjusted by moving the Y-axis linear module 2. For example, when the bent portion 53 and the next area to be bent 52 are arranged on both sides of the flow channel of the flying wing flat tube, the back-and-forth bending of the flying wing flat tube can be realized.

[0042] Optionally, the first drive structure 22 is a cylinder; the second drive structure 33 is an electric motor.

[0043] Optionally, the first drive structure 22 can drive the base plate 21 to move the rotating module 3 along the Y-axis by a distance not less than the thickness of the wing flat tube flow channel, and can be further selected as the thickness of the wing flat tube flow channel.

[0044] It should be noted that this invention does not limit the preset angle for bending the wing-shaped flat tube. In actual operation, the initial position of the input wing-shaped flat tube can be used as a reference to set a suitable bending angle. In an optional example of this embodiment, the preset angle can be set to rotate 90° clockwise or counterclockwise, and a Z-shaped wing-shaped flat tube can be obtained by bending back and forth; or rotate 180° clockwise or counterclockwise, such as... Figure 3 As shown, a serpentine flying wing flat tube can be obtained by bending it back and forth. Note that, for simplicity, the structure of a single flying wing is not shown in the figure.

[0045] Understandably, the drive structure included in the flying wing flat tube bending and forming device of this utility model can be automatically driven under the control of the controller, thereby improving operating efficiency and bending and forming accuracy.

[0046] Example 2

[0047] Based on the wing-shaped flat tube bending and forming device shown in Embodiment 1, the structure of the clamping component 31 has been optimized in this embodiment.

[0048] In an optional example of this embodiment, such as Figure 4As shown, the clamping assembly 31 includes a first push block 3111 and a second push block 3112 arranged parallel to each other. The ends of the first push block 3111 and the second push block 3112 near the feed are respectively provided with grooves that cooperate with the protruding ribs 51 on the upper and lower sides of the flying wing flat tube. The clamping assembly 31 also includes: a first bending substrate 3121 for fixing the first push block 3111; and a second bending substrate 3122 for fixing the second push block 3112. The first bending substrate 3121 and the second bending substrate 3122 are parallel to each other and perpendicular to the central axis of the mandrel 321. The ends of the first bending substrate 3121 and the second bending substrate 3122 away from the positioning assembly 32 are connected by a first vertical connecting plate 3123 to form a U-shaped receiving space that can support the bent flying wing flat tube. The lower part of the second bending substrate 3122 is connected to the output end of the first driving structure 22 through a second vertical connecting plate 3124. Thus, in actual operation, the rotational motion of the second drive structure 33 is transmitted to the second vertical connecting plate 3124, the second bending substrate 3122, the first vertical connecting plate 3123, and the first bending substrate 3121, and finally, by rotating the first push block 3111 and the second push block 3112, the bending area of ​​the wing flat tube held by the two is bent around the spindle 321 in the positioning assembly 32 to form the bent part 53.

[0049] In an optional example of this embodiment, there are multiple first vertical connecting plates 3123. When multiple vertically parallel first vertical connecting plates 3123 are provided, a connection surface can be provided for connecting other components.

[0050] In an optional example of this embodiment, a support plate 3129 is also included for connecting the second bending substrate 3122 and the first vertical connecting plate 3123 to improve the stability of the device and further improve the accuracy of the bending operation.

[0051] In an optional example of this embodiment, the clamping assembly 31 further includes: a fourth driving structure 3131 for driving the first push block 3111 to move up and down, the fourth driving structure 3131 being fixed to the first bending substrate 3121; and a fifth driving structure 3132 for driving the second push block 3112 to move up and down, the fifth driving structure 3132 being fixed to the second bending substrate 3122. In actual operation, after the wing-shaped flat tube to be bent is input, the first push block 3111 and the second push block 3112, which are set up vertically, can be driven by the fourth drive structure 3131 and the fifth drive structure 3132 to move towards the middle respectively. The grooves on the push blocks can fit with the ribs 51 on the upper and lower sides of the wing-shaped flat tube, thereby clamping the wing-shaped flat tube placed between the two push blocks in the vertical direction. After the bending of a bending area 52 is completed, the first push block 3111 and the second push block 3112 can be driven by the fourth drive structure 3131 and the fifth drive structure 3132 to move to the upper and lower ends respectively. The grooves on the push blocks will separate from the ribs 51 on the upper and lower sides of the wing-shaped flat tube, thereby releasing the wing-shaped flat tube in the vertical direction.

[0052] Optionally, the fourth drive structure 3131 is a cylinder. Optionally, the fifth drive structure 3132 is a cylinder.

[0053] In an optional example of this embodiment, the clamping assembly 31 further includes: a sixth driving structure 3133, which drives the first push block 3111 to move along the extension direction of the first bent substrate 3121 via a third push block 3113, and the third push block 3113 is slidably connected to the first bent substrate 3121; and a seventh driving structure 3134, which drives the second push block 3112 to move along the extension direction of the second bent substrate 3122 via a fourth push block 3114, and the fourth push block 3114 is slidably connected to the second bent substrate 3122. In actual operation, when the wing-shaped flat tube to be bent is input, the sixth drive structure 3133 and the seventh drive structure 3134 can drive the first push block 3111 and the second push block 3112 to move horizontally toward the wing-shaped flat tube through the third push block 3113 and the fourth push block 3114, so that the grooves on the first push block 3111 and the second push block 3112 fit with the ribs 51 on the upper and lower sides of the wing-shaped flat tube, thereby clamping the wing-shaped flat tube in the horizontal direction; after the bending of a bending area 52 is completed, the sixth drive structure 3133 and the seventh drive structure 3134 can drive the first push block 3111 and the second push block 3112 to move horizontally away from the wing-shaped flat tube through the third push block 3113 and the fourth push block 3114, so that the grooves on the first push block 3111 and the second push block 3112 separate from the ribs 51 on the upper and lower sides of the wing-shaped flat tube, thereby releasing the clamped wing-shaped flat tube in the horizontal direction.

[0054] Furthermore, in actual operation, the fourth drive structure 3131, the fifth drive structure 3132, the sixth drive structure 3133, and the seventh drive structure 3134 can be combined to achieve clamping and release of the flying wing flat tube in the vertical and horizontal directions, thereby improving the stability and accuracy of operation.

[0055] Optionally, the sixth drive structure 3133 is a cylinder. Optionally, the seventh drive structure 3134 is a cylinder.

[0056] In an optional example of this embodiment, combined with Figure 4 and Figure 5 The third pusher block 3113 is slidably connected to the first bent substrate 3121 via the second longitudinal linear guide pair 3125. Optionally, the fourth pusher block 3114 is slidably connected to the second bent substrate 3122 via the third longitudinal linear guide pair 3126.

[0057] In an optional example of this embodiment, the first push block 3111 is connected to the first bent substrate 3121 via the third push block 3113; further optionally, a first vertical connecting block 3115 is provided between the first push block 3111 and the third push block 3113, and the first vertical connecting block 3115 is connected to the first push block 3111 via the vertical extension and retraction of the first telescopic rod 31151.

[0058] In an optional example of this embodiment, the second push block 3112 is connected to the second bent substrate 3122 via the fourth push block 3114; further optionally, a second vertical connecting block 3116 is provided between the second push block 3112 and the fourth push block 3114, and the second vertical connecting block 3116 is connected to the second push block 3112 via the vertical extension and retraction of the second telescopic rod 31161.

[0059] In an optional example of this embodiment, a support plate 3127 is provided on the second bending substrate 3122 to support the bent wing flat tube segment. Further optionally, receiving plates 3128 are provided on both sides of the support plate 3127. The receiving plates 3128 are extensions of the support plate 3127, which can improve the stability of the receiving. In this optional example of this embodiment, the receiving plates 3128 extend downwards relative to the plane of the support plate 3127, facilitating the unloading of the wing flat tube after bending.

[0060] Example 3

[0061] Based on the wing-shaped flat tube bending and forming device shown in Embodiment 1, this embodiment optimizes the structure of the positioning component 32. Specifically: in an optional example of this embodiment, combined with Figure 4The central axis of the spindle 321 is perpendicular to the machine base 11. The spindle 321 includes a sleeved shaft 3211 and a fitting 3212. Either the shaft 3211 or the fitting 3212 is connected to the output end of the second drive structure 33, and the other is connected to the base plate 21 via a first support frame 34. The first support frame 34 is provided with a connecting platform 342 containing a first bearing 341. The first bearing 341 is a linear bearing. The shaft 3211 or the fitting 3212 is connected to the third drive structure 322 via the first bearing 341, and moves up and down along the central axis of the spindle 321 under the action of the third drive structure 322. In an optional example of this utility model, the third drive structure 322 is a cylinder.

[0062] In actual operation, the third drive structure 322 can drive the shaft 3211 and the kit 3212 to be engaged, thereby positioning the wing flat tube at the bending area 52 and guiding the wing flat tube to be bent around the mandrel 321.

[0063] Optionally, the shaft 3211 or the kit 3212 is connected to the output end of the second drive structure 33 via the positioning base 3213.

[0064] Optionally, the first bearing 341 is connected to the connecting platform 342 via a flange.

[0065] Example 4

[0066] Based on the flying wing flat tube bending and forming device shown in Embodiment 1, this embodiment optimizes the connection between the second drive structure 33 and the base plate 21. Specifically: in an optional example of this embodiment, combined with Figure 6 The output end of the second drive structure 33 passes through the machine base 11 and is mounted on the base plate 21 via the second bearing 331. The outer ring of the second bearing 331 is fixed to the base plate 21, and the inner ring is connected to the output end of the second drive structure 33. Thus, the second drive structure 33 can drive the rotating module 3 to bend the wing-shaped flat tube, but it cannot drive the Y-axis linear module 2 to rotate. The first drive structure 22 in the Y-axis linear module 2 can drive the Y-axis linear module 2 and the rotating module 3 to move along the Y-axis extension direction.
