[0003] In order to make the evaporator take up less space in the product, the evaporator aluminum tube is usually flattened; the flat tube shape of the aluminum tube is more suitable for small spaces (such as refrigerators and air conditioner evaporators), making it easier to arrange more pipes in a limited area and increase the overall heat exchange area.

Since there is a shaping plate 2 inside the aluminum tube 01, the shaping plate 2 has a supporting and shaping function for the flattened aluminum tube 01, so that the inner wall of the flattened aluminum tube 01 is smooth and not deformed, which is conducive to improving the problem of obstructed liquid flow inside the aluminum tube 01.

[0032] A support platform 7 is installed on the top surface of the substrate 1, and a rotating motor 71 is installed on the top surface of the support platform 7. The output shaft of the rotating motor 71 is connected to a rotating plate 72. The sides of both ends of the rotating plate 72 are connected to support rods 73. The end surface of the support rod 73 away from the rotating plate 72 is connected to a limiting plate 74; two shaping plates 2 are provided, and the two ends of the two shaping plates 2 are respectively connected to the end surfaces of the two limiting plates 74 away from the support rods 73. The thickness of the shaping plate 2 is the same as that of the limiting plate 74, and the width of the shaping plate 2 is smaller than the width of the limiting plate 74.

[0034] A flip motor 31 is installed on the side of the support frame 3 away from the support platform 7. The output shaft of the flip motor 31 is connected to the flip plate 32. A clamping cylinder 33 is installed at the end of the flip plate 32 close to the shaping plate 2. Both clamping jaws of the clamping cylinder 33 are installed with clamping plates 34. The two clamping plates 34 are used to clamp the flattened aluminum tube 01.

[0035] When the support frame 3 drives the pressure roller 5 to roll the aluminum tube 01 on the lower forming plate 2 again, the support frame 3 also drives the flip motor 31 to move, and the flip motor 31 drives the flip plate 32 and the clamping cylinder 33 to move, and the clamping cylinder 33 drives the splint 34 to open, so that the flattened aluminum tube 01 gradually enters between the two splints 34; when the lower aluminum tube 01 is flattened, the splint 34 moves to the middle position of the flattened aluminum tube 01, and the clamping cylinder 33 clamps the aluminum tube 01 again; when the support frame 3 returns to its original position, the clamping cylinder 33 removes the flattened aluminum tube 01 from the forming plate 2, and the flip motor 31 drives the flip plate 32 to rotate to the other side, and the clamping cylinder 33 opens the splint 34, so that the flattened aluminum tube 01 can be unloaded.

[0036] The side of the upper support seat 9 away from the support platform 7 is connected to a support plate 35, and the top surface of the end of the support plate 35 close to the clamping plate 34 is connected to a wedge block 36. The inclined surface of the wedge block 36 faces the shaping plate 2, and the top surface of the wedge block 36 is used to support the upper aluminum tube 01 to a horizontal state.

[0037] When the clamping plates 34 move toward the aluminum tube 01 , the wedge block 36 gradually supports the aluminum tube 01 , whose end may fall, through the inclined surface, so that the aluminum tube 01 is in a horizontal state, making it easier for the aluminum tube 01 to enter between the two clamping plates 34 .

[0038] Two vertical plates 8 are installed on the top surface of the base plate 1, and a feeding pipe 81 is passed through the top of the two vertical plates 8. The feeding pipe 81 is used for the aluminum tube 01 to enter after straightening. The feeding pipe 81 is aligned with the shaping plate 2, and the end of the feeding pipe 81 is away from the trumpet-shaped guide pipe 82 of the shaping plate 2; a cutting machine 12 is installed on the top surface of the base plate 1, and a second transverse movement mechanism 13 for driving the cutting machine 12 to move toward the aluminum tube 01 is installed on the top surface of the base plate 1. The cutting machine 12 is used to cut the aluminum tube 01; a first cylinder 91 is driven and installed on the two support seats 9. The first cylinder 91 is located on the side of the hydraulic cylinder 4 away from the feeding pipe 81, and the piston rod ends of the first cylinder 91 are connected to a second U-shaped bracket 92. A rubber roller 93 is rotatably connected between the two ends of the second U-shaped bracket 92; a second driving mechanism 10 for driving the rubber roller 93 to rotate is installed on the second U-shaped bracket 92, and the aluminum tube 01 is located between the two rubber rollers 93.

[0039] The entire straightened aluminum tube 01 enters the feed tube 81 from the guide tube 82, comes out of the feed tube 81, and is then inserted into the interior by the shaping plate 2. When the aluminum tube 01 is fed to the set length, the second transverse movement mechanism 13 drives the cutting machine 12 to cut the aluminum tube 01 passing through the feed tube 81. The first cylinder 91 drives the rubber roller 93 to descend, and the rubber roller 93 contacts the surface of the aluminum tube 01. The second driving mechanism 10 drives the rubber roller 93 to rotate, and the rubber roller 93 drives the aluminum tube 01 forward through friction until the end of the aluminum tube 01 passes over the pressing roller 5 and contacts the end face of the limit plate 74, so that the pressing roller 5 can roll from the end of the aluminum tube 01.

[0040] Two sliding rods 83 are passed through the top of the vertical plate 8 near the support frame 3. The two sliding rods 83 are respectively located on both sides of the feed pipe 81. The ends of the two sliding rods 83 near the shaping plate 2 are connected with connecting blocks 84. A support ring 85 is connected between the two connecting blocks 84, and the aluminum tube 01 passes through the support ring 85; the other ends of the two sliding rods 83 are connected to a baffle 86, and a first spring 87 is sleeved on the sliding rod 83. One end of the first spring 87 is pressed against the side of the vertical plate 8, and the other end of the first spring 87 is pressed against the connecting block 84; a second cylinder 37 is installed on the side of the support frame 3 near the shaping plate 2, and the bottom end of the piston rod of the second cylinder 37 is connected to a U-shaped push plate 38. The U-shaped push plate 38 is located between the support ring 85 and the shaping plate 2, and the aluminum tube 01 passes through the U-shaped push plate 38.

[0041] Under the action of the first spring 87, the support ring 85 moves toward the shaping plate 2, and the connecting block 84 pulls the slide bar 83 to slide in the vertical plate 8, so that the support ring 85 is away from the feed pipe 81, and the aluminum tube 01 extending from the feed pipe 81 enters the support ring 85. The support ring 85 supports the aluminum tube 01, so that the aluminum tube 01 is in a horizontal state, the end of the aluminum tube 01 is not easy to fall, and the aluminum tube 01 is easier to be inserted into the shaping plate 2; when it is necessary to cut the aluminum tube 01, the second cylinder 37 drives the U-shaped The push plate 38 descends, and when the support frame 3 moves back, the U-shaped push plate 38 pushes the support ring 85 to move toward the feed pipe 81, and the support ring 85 drives the connecting block 84 to compress the first spring 87. When the U-shaped push plate 38 passes over the saw blade of the cutting machine 12, it stops moving, and cutting can be carried out at this time. After the cutting is completed, the cutting machine 12 is retracted, and the support frame 3 moves forward, gradually releasing the push of the U-shaped push plate 38 on the support ring 85, and then the second cylinder 37 drives the U-shaped push plate 38 to rise.

[0042] Both support seats 9 are equipped with a third cylinder 94, which is located on the side of the first cylinder 91 away from the hydraulic cylinder 4. The piston rods of the third cylinder 94 are equipped with semicircular snap rings 95. The inner circumferences of the two semicircular snap rings 95 are attached to the outer wall of the aluminum tube 01, and the two semicircular snap rings 95 form a circular ring.

[0043] After the aluminum tube 01 passes through the pressing roller 5 and the rubber roller 93 , the aluminum tube 01 enters between the two semicircular arc-shaped clamping rings 95 . The two semicircular arc-shaped clamping rings 95 cooperate with the shaping plate 2 to support the aluminum tube 01 and improve the stability of the aluminum tube 01 .

[0044] The support rod 73 is slidably connected to a sliding tube 75, and the sliding tube 75 is sleeved on the outer peripheral surface of the end of the aluminum tube 01. The support rod 73 is sleeved with a second spring 76. One end of the second spring 76 is pressed tightly against the side of the rotating plate 72, and the other end of the second spring 76 is pressed tightly against the end surface of the sliding tube 75. The limit plate 74 is located inside the sliding tube 75.

[0045] When the support frame 3 moves toward the support platform 7, the semicircular arc-shaped clamping ring 95 pushes the slide tube 75, and the slide tube 75 compresses the second spring 76; when the aluminum tube 01 is flattened, the semicircular arc-shaped clamping ring 95 moves back, and the push of the semicircular arc-shaped clamping ring 95 on the slide tube 75 is released, and the semicircular arc-shaped clamping ring 95 and the slide tube 75 are separated. At this time, under the elastic force of the second spring 76, the second spring 76 pushes the slide tube 75, and the slide tube 75 pushes the flattened aluminum tube 01, so that the aluminum tube 01 is loosened and moves forward, which is convenient for the subsequent splint 34 to cut the aluminum tube 01.

[0046] The first drive mechanism 6 and the second drive mechanism 10 have the same structure. The first drive mechanism 6 and the second drive mechanism 10 both include a drive motor 61, a synchronous wheel 62 and a synchronous belt 63. The drive motor 61 is installed on the first U-shaped bracket 41 and the second U-shaped bracket 92. Two synchronous wheels 62 are provided, one of which is coaxially connected to the output shaft of the drive motor 61, and the other synchronous wheel 62 is coaxially connected to the rotating shaft of the pressure roller 5 and the rotating shaft of the rubber roller 93; the synchronous belt 63 is wound around the two synchronous wheels 62.

[0047] The first transverse movement mechanism 11 and the second transverse movement mechanism 13 have the same structure, both of which are ball screw slide modules. The cutting machine 12 and the support frame 3 are both slidably installed on the linear guide rail of the ball screw slide module, and the cutting machine 12 and the support frame 3 are driven to slide by the slide.

[0048] The implementation principle of an aluminum tube flattening processing device for an evaporator in an embodiment of the present application is as follows: when the aluminum tube 01 needs to be flattened, the first transverse movement mechanism 11 drives the support frame 3 to move, and the support frame 3 drives the pressure roller 5 to move to one end of the aluminum tube 01, and then the hydraulic cylinder 4 drives the first U-shaped bracket 41 to move toward the shaping plate 2, and the first U-shaped bracket 41 drives the pressure roller 5 to move toward the shaping plate 2. The two pressure rollers 5 reach the set position, and the first driving mechanism 6 drives the pressure roller 5 to rotate. The first transverse movement mechanism 11 drives the support frame 3 to drive the pressure roller 5 to move toward the other end of the aluminum tube 01, and the pressure roller 5 rolls on the surface of the aluminum tube 01 to flatten the aluminum tube 01. Since there is a shaping plate 2 inside the aluminum tube 01, the shaping plate 2 has a supporting and shaping function for the flattened aluminum tube 01, so that the inner wall of the flattened aluminum tube 01 is smooth and not deformed, which is beneficial to improving the problem of obstructed liquid flow inside the aluminum tube 01.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
