[0001] This utility model relates to the technical field of heat exchange fin processing equipment, specifically to a device for intermittently cutting the fins of a flying wing flat tube. Background Technology

[0002] Flying wing flat tubes are a special type of finned heat exchange tube. They are made by directly carving heat dissipation fins (fins) onto the surface of aluminum alloy or other machinable materials through a continuous slicing process. Compared with traditional finned heat exchange tubes, flying wing flat tubes eliminate contact thermal resistance in the heat conduction process, effectively improving heat transfer efficiency.

[0003] With the increasing application of finned heat exchange tubes in air conditioning, power plants, and petrochemicals, the demand for processing finned flat tubes has also increased. For example, to adapt to more compact spatial layouts and increase heat exchange area, finned flat tubes need to be bent into shape. Before this, the fins on one side of the finned flat tube need to be cut off at intervals to provide a bendable area for the bending process. Utility Model Content

[0039] Example 1

[0040] A device for intermittently cutting the fins of a flying wing flat tube, such as Figure 1 As shown, it includes:

[0041] Machine base 1, with the following mounted on its upper surface:

[0042] Operating platform 411;

[0043] A vertical transmission mechanism that drives the flying wing flat tube to achieve intermittent motion;

[0044] Among them, a wing-cutting assembly is installed on the operating table 411, which cuts off the outer surface of the wing-shaped tube from top to bottom when the tube is stationary, and is located below the cutter head in the cutting mechanism; wherein, the wing-cutting assembly is installed on the operating table via a movable structure, and the wing-cutting assembly includes:

[0045] A left-side fin-cutting assembly 401 for cutting off the fins 52 on the left side surface of the wing flat tube; the left-side fin-cutting assembly 401 includes a left-side cutting mechanism and a left-side lifting mechanism that drives the left-side cutting mechanism to move back and forth in the vertical direction.

[0046] And / or, a right-side fin-cutting assembly 402 for cutting off the fins 52 on the right side surface of the wing flat tube; the right-side fin-cutting assembly 402 includes a right-side cutting mechanism and a right-side lifting mechanism that drives the right-side cutting mechanism to reciprocate in the vertical direction.

[0047] It should be noted that, in combination Figure 2 In this embodiment, the flying wing flat tube includes a flow channel and fins 52 shoveled on the two wider sides of the flow channel. The two narrower sides of the flow channel of the flying wing flat tube are provided with raised ribs 51. It should be noted that, because the fins 52 shoveled on both sides of the flying wing flat tube are thin and densely arranged, for the sake of brevity... Figure 2 The structure of a single fin 52 is not shown. Furthermore, vertical transmission is used to describe a flying wing flat tube conveying method in which the two wider sides of the upper flow channel of the flying wing flat tube are set as the left and right sides, and the two narrower sides are set as the top and bottom sides.

[0048] It should be noted that in this invention, by the reciprocating movement of the cutting mechanism in a single wing-cutting assembly, combined with the operation of the intermittent vertical conveying mechanism for forward transport of the wing flat tube, the fins 52 on one side of the wing flat tube can be cut off at intervals, resulting in a wing flat tube with spaced bending areas 53. Understandably, the frequency of the reciprocating motion of the cutting mechanism in this invention can be set in advance as needed, and the distance between adjacent bending areas 53 on the same wing flat tube can be the same or different. By setting two wing-cutting assemblies on the same operating table 411, the fins 52 on both sides of the same wing flat tube can be cut off separately, resulting in wing flat tubes with adjacent bending areas 53 on both sides having the same or different intervals. Furthermore, the width of the bending area 53 is affected by the width of the cutting end in the cutting mechanism. In actual operation, cutting blades 4211 with the same or different widths can be used in the cutting mechanisms of multiple wing-cutting assemblies as needed, thereby providing more diverse wing flat tubes for subsequent bending and forming operations.

[0049] In this embodiment, the device for intermittently cutting the fins of the flying wing flat tube includes two fin-cutting assemblies, which are respectively arranged on the left and right sides of the flying wing flat tube and staggered front and back. This allows the two fin-cutting assemblies to intermittently cut the fins 52 on both sides of the flying wing flat tube to form the bending area 53. In the subsequent bending and forming operation, the bending area 53 of the flying wing flat tube can be bent twice to obtain a compactly arranged serpentine heat exchange tube.

[0050] Optionally, the machine base 1 is mounted on the frame 11, which supports the machine base 1. It should be noted that the specific structure of the frame 11 used in this invention is not limited; any structure that can support the machine base 1 is acceptable.

[0051] Optionally, the upper surface of the operating table 411 is provided with a working hole 4112 to facilitate the passage of the cutting mechanism in the cutting assembly.

[0052] The process of using the intermittent fin cutting device of this embodiment includes: vertically and intermittently feeding the wing-shaped flat tube; when the wing-shaped flat tube reaches below the fin cutting assembly, the vertical conveying mechanism stops conveying, and the cutting mechanism passes through the working hole 4112, its cutting head cutting off the fins 52 on one side of the wing-shaped flat tube by moving downwards, thus forming a bending area 53 on the wing-shaped flat tube; after the cutting operation is completed, the cutting mechanism rises, and then the wing-shaped flat tube continues to be conveyed under the action of the vertical conveying mechanism; when the wing-shaped flat tube continues to be conveyed to a certain position, the cutting mechanism will again perform the "descend-fin cutting-rise" operation, forming a new bending area 53 on the wing-shaped flat tube below it, until the fin cutting operation of the entire wing-shaped flat tube is completed. The overall fin cutting operation is continuous, highly operable, and can continuously produce a large number of wing-shaped flat tubes with bending areas 53, continuously providing sufficient raw materials for the downstream bending and forming section.

[0053] Optionally, the movable structure includes: a wing-cutting support plate 423 for fixing the wing-cutting assembly to the operating table 411; wherein the operating table 411 further includes two track seats 4113 symmetrically arranged on both sides of the upper surface along the conveying direction of the wing flat tube; the wing-cutting support plate 423 is parallel to the upper surface of the operating table 411 and its two ends are respectively connected to the two track seats 4113.

[0054] Further optionally, any one of the cutting mechanisms is connected to the lower surface of the wing cutting support plate 423, and any one of the lifting mechanisms is connected to the upper surface of the wing cutting support plate 423.

[0057] Cutting blade 4211, the cutting edge of cutting blade 4211 is a cutting head;

[0058] Cutter holder 4212 is used to fix cutter 4211; combined with Figure 4 The mounting end of the cutter 4211 is connected to the cutter holder 4212, and the cutting end extends out of the cutter holder 4212. In this embodiment, the cutting end of the cutter 4211 is the cutter head, and the mounting end is the non-cutting part on the cutter 4211 that is opposite to the cutter head.

[0059] The first connecting seat 4213 and the cutter seat 4212 are connected to the power output end of the lifting mechanism via the first connecting seat 4213. In actual operation, the power output end of the lifting mechanism is connected to the first connecting seat 4213 to drive the cutter seat 4212 and the cutter 4211 to reciprocate in a direction perpendicular to the upper surface of the operating table 411.

[0060] The second connecting seat 4214 is fixed to the movable structure and slidably connected to the cutter seat 4212; thereby providing support for the cutter mechanism and improving the stability of the cutter mechanism's up-and-down reciprocating motion. Optionally, the second connecting seat 4214 and the cutter seat 4212 are slidably connected via a second guide rail pair 4215.

[0063] The first drive mechanism 4221, lead screw 4222 and lead screw nut 4223 are connected to the cutting mechanism. The lead screw 4222 is set in a direction perpendicular to the upper surface of the operating table 411. The first drive mechanism 4221 can drive the cutter head to reciprocate through the lead screw 4222 and lead screw nut 4223 to cut off the fins 52 of the winged flat tube on the cutter head side.

[0064] Optionally, the lifting mechanism also includes a lifting mechanism fixing seat, and the first drive mechanism 4221 is fixed to the movable structure through the lifting mechanism fixing seat 42211.

[0065] Optionally, the first drive mechanism 4221 is a motor.

[0071] It should be noted that the specific structure and shape of the pressure frame 4243 are not limited in this embodiment. The pressure effect can be achieved by contacting the protruding rib 51 on the top of the wing-shaped flat tube at its end. Optionally, the end of the pressure frame 4243 is provided with a second groove that cooperates with the protruding rib 51 on the top of the wing-shaped flat tube.

[0072] Optionally, the pressure frame 4243 is provided with a clearance opening corresponding to the space occupied by the cutting mechanism, allowing the cutting mechanism to reciprocate within the clearance opening.

It should be noted that the size and shape of the clearance opening are not limited in this embodiment. Figure 4 An alternative example is shown, which can be configured according to the shape and relative position of the cutting mechanism and the pressure holder 4243 in actual operation.
