Description

Technical Field

[0001] This utility model belongs to the technical field of evaporator aluminum tube processing equipment, specifically referring to an aluminum tube processing device for air conditioner evaporators. Background Technology

[0002] An air conditioner evaporator is a type of evaporator. The function of an air conditioner evaporator is to utilize the fact that liquid low-temperature refrigerant is easy to evaporate under low pressure, turning into vapor and absorbing heat from the medium being cooled to achieve the purpose of cooling. The main structure of an air conditioner evaporator includes cooling coils. The refrigerant flows in the coils to complete heat exchange. Aluminum tubes themselves have good corrosion resistance and light weight, so aluminum tubes are often used to manufacture the cooling coils of evaporators.

[0003] When manufacturing cooling coils using aluminum tubes, the tubes need to be bent and arranged to reduce the evaporator volume and improve cooling efficiency. Current processing methods typically involve using a tube bending machine to bend the aluminum tubes. However, this bending machine applies significant pressure to the aluminum tube surface, causing wrinkles to easily form. Furthermore, existing aluminum tube bending machines clamp and fix one end of the tube during operation, leading to an imbalance of forces at both ends during bending, generating significant stress, reducing the tube's structural strength, and making it prone to cracking during heat exchange. Therefore, a processing device is needed that can eliminate stress and wrinkling during aluminum tube bending. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an aluminum tube processing device for air conditioner evaporators, so as to at least partially solve the above technical problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes an aluminum tube processing device for air conditioner evaporators, including an aluminum tube bending kit, an aluminum tube center positioning component, a bending power component, and a processing worktable. The aluminum tube bending kit and the aluminum tube center positioning component are disposed on the processing worktable, and the bending power component is disposed below the aluminum tube center positioning component. The processing worktable has a fully penetrating arc-shaped groove and a central through hole, with the central through hole located at the center of the arc-shaped groove. The aluminum tube bending kit includes an aluminum tube sleeve and a movable base. The aluminum tube sleeve is fixedly disposed on the movable base, and the movable base is slidably disposed in the arc-shaped groove. The aluminum tube sleeve is used to clamp the aluminum tube. The aluminum tube center positioning component includes a center stator and a second rotor. The center stator is fixedly disposed in the central through hole, and a first rotor is disposed on the center stator. The first rotor is rotatably connected to the center stator, and the second rotor is rotatably disposed on the processing worktable. The bending power component is used to drive the movement of the movable base.

[0006] Furthermore, the aluminum tube bending kit also includes a stress relief component, which is disposed on both sides of the aluminum tube sleeve. The aluminum tube sleeve has a through side opening. The stress relief component is provided with a telescopic wheel, a torque motor, and a transmission chain. The telescopic wheel is rotatably connected to the stress relief component. The position of the telescopic wheel corresponds to the position of the side opening. The telescopic wheel is provided with an end gear. The torque motor is connected to the end gear through the transmission chain. The torque motor is configured to drive the rotation of the telescopic wheel through the transmission chain and the end gear.

[0007] Furthermore, the stress relief assembly is also provided with a telescopic link and a compression spring, the telescopic wheel is provided on the telescopic link, and the two ends of the compression spring are connected to the stress relief assembly and the telescopic wheel.

[0008] Furthermore, the center stator is provided with a fixing nut, and the center stator is fixedly installed in the center through hole by the fixing nut; the side of the first rotor is provided with a first arc-shaped groove, and the side of the second rotor is provided with a second arc-shaped groove, and the center positions of the arc edges of the second rotor and the second arc-shaped groove coincide.

[0009] Furthermore, the processing worktable is provided with a positioning ruler and a positioning block. The position of the positioning ruler corresponds to the position of the aluminum tube sleeve. The positioning ruler and the positioning block are used to calibrate the position of the aluminum tube sleeve.

[0010] Furthermore, the bending power assembly includes a hydraulic motor and a power sleeve. The output shaft of the hydraulic motor is located directly below the central through hole. An extension rod is provided on the output shaft of the hydraulic motor. The power sleeve is fixedly mounted on the extension rod. The movable base is fixedly connected to the power sleeve. The hydraulic motor drives the movable base to move in the arc-shaped through groove through the extension rod and the power sleeve.

[0011] Furthermore, the bending power assembly also includes a lifting bracket and a sleeve slide rail. The hydraulic motor is mounted on the lifting bracket, and the power sleeve is slidably mounted on the sleeve slide rail, which supports the power sleeve.

[0012] Furthermore, the processing workbench is equipped with an aluminum tube end cutting assembly, which includes an aluminum tube pad, a cutting tool, and a lifting mechanism. The aluminum tube pad is fixedly installed on the processing workbench, and the cutting tool is mounted on the lifting mechanism. The lifting mechanism is used to control the raising and lowering of the cutting tool, and the cutting tool is used to cut the end of the aluminum tube.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The two aluminum tube sleeves are driven to move in the arc-shaped through groove by the moving base. During the movement of the aluminum tube sleeves, the aluminum tube is bent. At this time, the distance between the aluminum tube sleeves on both sides of the aluminum tube as the clamping position and the bending position is equal.

[0015] 3. In this utility model, both the first rotor and the second rotor can rotate relative to the surface of the aluminum tube, converting the sliding friction at the bending position of the aluminum tube into rolling friction, reducing the tangential force on the surface of the aluminum tube, thereby avoiding wrinkling on the surface of the aluminum tube.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The aluminum tube processing device proposed in this embodiment is mainly used for processing aluminum tubes for air conditioner evaporators. Existing aluminum tube bending machines clamp one end of the aluminum tube when bending it, which causes uneven stress on both sides of the bending position, resulting in large internal stress on the aluminum tube and reducing its structural strength. At the same time, the aluminum tube is subjected to large tangential force during bending, which may cause surface wrinkling and affect the quality of the aluminum tube.

[0022] like Figures 1-11 As shown, this embodiment includes an aluminum tube bending kit 100, an aluminum tube center positioning component 200, a bending power component 300, and a processing worktable 400. The aluminum tube bending kit 100 and the aluminum tube center positioning component 200 are disposed on the processing worktable 400. The bending power component 300 is disposed below the aluminum tube center positioning component 200. The aluminum tube bending kit 100 moves on the processing worktable 400 to clamp and bend the aluminum tube. The aluminum tube center positioning component 200 is fixedly disposed on the processing worktable 400 to position the bending position of the aluminum tube. The bending power component 300 is disposed on the processing worktable 400 to drive the movement of the aluminum tube bending kit 100.

[0023] The aluminum tube bending kit 100 proposed in this embodiment includes an aluminum tube sleeve 101 and a movable base 102. The aluminum tube sleeve 101 is disposed on the movable base 102. An arc-shaped through groove 402 and a central through hole 403 are provided on the processing operation table 400. The central through hole 403 is located at the center of the arc-shaped through groove 402. The aluminum tube sleeve 101 is fixedly disposed on the movable base 102, and the movable base 102 is slidably disposed in the arc-shaped through groove 402. The aluminum tube center positioning component 200 proposed in this embodiment includes a center stator 201 and a second rotor 205. The center stator 201 is fixedly disposed in the central through hole 403. A first rotor 203 is provided on the center stator 201. The first rotor 203 is rotatably connected to the center stator 201. The second rotor 205 is rotatably disposed on the processing operation table 400.

[0024] In this embodiment, two aluminum tube bending kits 100 are respectively provided in the arc-shaped through grooves 402 on both sides of the central through hole 403. Each aluminum tube bending kit 100 is set in the arc-shaped through groove 402 through the movable base 102. First, the aluminum tube to be bent is inserted into the aluminum tube sleeve 101 on one side, then passes between the first rotor 203 and the second rotor 205, and finally comes out from the aluminum tube sleeve 101 on the other side. At this time, the aluminum tube is fixed. That is, the center position of the aluminum tube is used as the bending position and is limited in the first rotor 203 and the second rotor 205. The two sides of the aluminum tube are respectively fixed in the aluminum tube sleeves 101 on both sides of the bending position.

[0025] Subsequently, the bending power assembly 300 drives the two aluminum tube sleeves 101 to move in the arc-shaped through groove 402 via the movable base 102. During the movement of the aluminum tube sleeves 101, the aluminum tube is bent. At this time, the distance between the aluminum tube sleeves 101 on both sides of the aluminum tube as the clamping position and the bending position is equal. Therefore, the torque on both sides of the aluminum tube at the bending position is equal, the forces on both sides of the aluminum tube are balanced, the stress generated on the aluminum tube is reduced, and the structural strength of the aluminum tube is improved.

[0026] Since the first rotor 203 and the second rotor 205 do not rigidly clamp the aluminum tube, when the torques on both sides of the aluminum tube are different during actual use, the aluminum tube can move slightly between the first rotor 203 and the second rotor 205 to ensure that the bending torques on both sides of the aluminum tube are equal, thereby avoiding the generation of stress.

[0027] At the same time, both the first rotor 203 and the second rotor 205 can rotate relative to the surface of the aluminum tube, converting the sliding friction at the bending position of the aluminum tube into rolling friction, reducing the tangential force on the surface of the aluminum tube, thereby preventing wrinkling from occurring on the surface of the aluminum tube.

[0028] The aluminum tube bending kit 100 proposed in this embodiment also includes a stress relief component 103. The stress relief component 103 is disposed on both sides of the aluminum tube sleeve 101. The aluminum tube sleeve 101 is provided with a through side opening 104. The stress relief component 103 is provided with a telescopic wheel 105, a torque motor 106 and a transmission chain 107. The telescopic wheel 105 is rotatably connected to the stress relief component 103. The position of the telescopic wheel 105 corresponds to the position of the side opening 104. The telescopic wheel 105 is provided with an end gear 110. The torque motor 106 is connected to the end gear 110 through the transmission chain 107. The torque motor 106 is configured to drive the rotation of the telescopic wheel 105 through the transmission chain 107 and the end gear 110.

[0029] In this embodiment, when in use, the telescopic wheel 105 passes through the side opening 104 and contacts the surface of the aluminum tube. When the torque motor 106 is working, it drives the telescopic wheel 105 to rotate through the transmission chain 107. When the telescopic wheel 105 rotates, it generates friction on the surface of the aluminum tube. The friction generated by the telescopic wheel 105 offsets part of the shear force that the aluminum tube is subjected to when it is bent, thereby further reducing the stress generated during the bending of the aluminum tube, and also preventing delamination and wrinkling on the surface of the aluminum tube.

[0030] By setting multiple side openings 104 and telescopic wheels 105 to work together, friction is applied at multiple locations on the aluminum tube, thereby more comprehensively eliminating the stress generated when the aluminum tube is bent, improving the structural strength of the aluminum tube, and reducing the possibility of the aluminum tube being damaged or broken.

[0031] The stress relief component 103 proposed in this embodiment is also provided with a telescopic connecting rod 108 and a compression spring 109. The telescopic rotating wheel 105 is provided on the telescopic connecting rod 108. The two ends of the compression spring 109 are connected to the stress relief component 103 and the telescopic rotating wheel 105. The telescopic rotating wheel 105 provided in this embodiment is provided on the telescopic connecting rod 108 to realize telescopic movement. At the same time, the compression spring 109 is connected to the telescopic rotating wheel 105. The elastic force generated by the compression spring 109 pushes the compression spring 109 to move into the aluminum tube sleeve 101, and at the same time, the length of the telescopic connecting rod 108 extends.

[0032] In actual use, the elastic force generated by the compression spring 109 pushes the telescopic wheel 105 to press tightly against the surface of the aluminum tube. At the same time, when a larger diameter aluminum tube is inserted into the aluminum tube sleeve 101, the aluminum tube can also push the telescopic wheel 105 to compress the length of the compression spring 109 and the telescopic connecting rod 108, ensuring that the aluminum tube can be inserted into the aluminum tube sleeve 101. By setting the elastic compression spring 109 and the telescopic connecting rod 108 with variable length, the adaptability of the stress relief component 103 is improved. It will not interfere with the aluminum tube while ensuring that the telescopic wheel 105 and the aluminum tube always maintain close contact, which is suitable for aluminum tubes of various sizes.

[0033] The central stator 201 proposed in this embodiment is provided with a fixing nut 202. The central stator 201 is fixedly installed in the central through hole 403 by the fixing nut 202. The side of the first rotor 203 is provided with a first arc-shaped groove 204, and the side of the second rotor 205 is provided with a second arc-shaped groove 206. The center positions of the arc edges of the second rotor 205 and the second arc-shaped groove 206 coincide. The first arc-shaped groove 204 and the second arc-shaped groove 206 are respectively provided on the first rotor 203 and the second rotor 205, so that the first rotor 203 and the second rotor 205 cover the aluminum tube, increase the contact area with the bending position of the aluminum tube, reduce the pressure generated at the bending position, and avoid the aluminum tube from cracking at the bending position.

[0034] The processing worktable 400 proposed in this embodiment is provided with a positioning scale 404 and a positioning block 405. The position of the positioning scale 404 corresponds to the position of the aluminum tube sleeve 101. The positioning scale 404 and the positioning block 405 are used to mark the position of the aluminum tube sleeve 101. When the aluminum tube sleeve 101 is in the initial position, the central axis of the aluminum tube sleeve 101 passes through the positioning scale 404 and between the first rotor 203 and the second rotor 205. At the same time, the movable base 102 abuts against the positioning block 405. At this time, the aluminum tube can be inserted into the aluminum tube sleeve 101.

[0035] By setting the positioning scale 404 and the positioning stop 405, the initial position of the aluminum tube sleeve 101 is restricted and calibrated to ensure that the aluminum tube can be smoothly inserted into the aluminum tube sleeve 101 and pass between the first rotor 203 and the second rotor 205.

[0036] The bending power assembly 300 proposed in this embodiment includes a hydraulic motor 301 and a power sleeve 304. The output shaft of the hydraulic motor 301 is located directly below the central through hole 403. An extension rod 303 is provided on the output shaft of the hydraulic motor 301. The power sleeve 304 is fixedly mounted on the extension rod 303. The movable base 102 is fixedly connected to the power sleeve 304. The hydraulic motor 301 drives the movable base 102 to move in the arc-shaped through groove 402 through the extension rod 303 and the power sleeve 304. Two hydraulic motors 301 are provided to drive two power sleeves 304 to move on the sleeve slide rail 305, thereby realizing the driving of the two aluminum tube sleeves 101.

[0037] The hydraulic motor can provide a large output torque, ensuring that the aluminum tube sleeve 101 can bend the aluminum tube. At the same time, by adjusting the speed and rotation angle of the hydraulic motor 301, the aluminum tube can be bent into different angles, which can meet most processing needs.

[0038] The bending power assembly 300 proposed in this embodiment also includes a lifting bracket 302 and a sleeve slide rail 305. The hydraulic motor 301 is mounted on the lifting bracket 302, and the power sleeve 304 is slidably mounted on the sleeve slide rail 305. The sleeve slide rail 305 is used to support the power sleeve 304. By mounting the power sleeve 304 on the sleeve slide rail 305, the weight of the aluminum tube is applied to the sleeve slide rail 305 through the movable base 102, which avoids the extension rod 303 from being subjected to excessive downward force, thereby reducing the frictional resistance experienced by the extension rod 303 when rotating.

[0039] This embodiment also includes an aluminum tube end cutting assembly 401, which is set on the processing worktable 400 and is used to cut the end of the bent aluminum tube. The lengths of the two sides of the bent aluminum tube are equal after cutting, and the end is flatter, which is convenient for subsequent use in the manufacture of evaporators.

[0040] Specifically, the aluminum tube end cutting assembly 401 includes an aluminum tube pad 406, a cutting tool 407, and a lifting mechanism 408. The aluminum tube pad 406 is used to support and cushion the end of the aluminum tube, the cutting tool 407 is used to cut the end of the aluminum tube, and the lifting mechanism 408 is used to drive the cutting tool 407 to move up and down.

[0041] When in use, the aluminum tube sleeve 101 moves to swing the bent aluminum tube onto the aluminum tube pad 406. Then, the lifting platform 408 drives the cutting tool 407 to move downward until the cutting tool 407 contacts the aluminum tube and cuts the end of the aluminum tube. After the cutting is completed, the lifting platform 408 drives the cutting tool 407 to move upward and return to its original position so that the next cutting can be carried out.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
