Description

Technical Field

[0001] This invention relates to the technical field of aluminum flat tube processing, and in particular to a straightening device for aluminum flat tube processing. Background Technology

[0002] Aluminum flat tubes are tubing made primarily of aluminum through extrusion or welding processes, and come in various specifications and applications. During the processing of aluminum flat tubes, straightening devices are used to straighten them.

[0003] The prior art patent CN118060364A discloses a microchannel aluminum flat tube straightening device. The device supports and reinforces the internal structure of the aluminum flat tube clamping position through a reinforcing component. The pressure rod and rack work together to drive the gear and rotating rod to rotate. At the same time, the top block rotates and pushes the protrusion to the upper and lower sides, causing the support block to move closer to the inner wall of the aluminum flat tube. This supports and reinforces the internal structure of the aluminum flat tube clamping position, preventing deformation of the aluminum flat tube due to excessive clamping force during the clamping process. This ensures the surface quality of the aluminum flat tube and allows it to remain stable during the straightening process, which is beneficial to improving the straightness requirements of the aluminum flat tube after straightening.

[0004] However, in actual processing, because the aluminum flat tube is clamped and fixed by the clamping unit, the upper part of the aluminum flat tube is blocked by the clamping unit. Therefore, when it is necessary to straighten the clamped part of the aluminum flat tube, the clamping unit must be released and the clamping position of the aluminum flat tube must be readjusted before the aluminum flat tube can continue to be straightened. The operation is time-consuming and laborious, reducing the efficiency of processing. Summary of the Invention

[0029] The first driving structure includes two horizontal plates 12 connected to the base plate 1. The two horizontal plates 12 are provided with anti-deformation structures. A first driving groove 13 is opened on the right side of each horizontal plate 12, and a second driving groove 15 is opened on the left side of each horizontal plate 12. The corresponding second driving groove 15 is connected to the first driving groove 13. The front and rear ends of the right lifting plate 8 are connected to the first driving rod 11. The first driving rod 11 moves through the first driving groove 13. The front and rear ends of the left lifting plate 8 are connected to the second driving rod 14. The second driving rod 14 passes through the second driving groove 15.

[0030] The alternating movement structure includes horizontal grooves 17 formed on the left and right sides of the substrate 1. A first transmission rod 18 is rotatably connected between the two end walls of the right horizontal groove 17. A first spiral groove 19 is formed on the upper right section of the first transmission rod 18, and a first straight groove 20 is formed on the upper left section of the first transmission rod 18, connecting to the first spiral groove 19. One end of the first transmission rod 18 is connected to a right-side screw 3. A second transmission rod 21 is rotatably connected between the two end walls of the left horizontal groove 17. A second spiral groove 22 is formed on the upper left section of the second transmission rod 21, connecting to the second spiral groove 22. A second straight groove 20 is formed on the upper right section of the second transmission rod 21, connecting to the second spiral groove 22. The groove 23, one end of the second transmission rod 21 is connected to a screw 3 on the left side, the front of the base plate 1 has a groove 29 in the middle, an electric push rod 27 is installed on the groove wall at one end of the groove 29, one end of the output shaft of the electric push rod 27 is connected to a push block 28, a U-shaped plate 26 is set on the push block 28, both ends of the U-shaped plate 26 are fastened to the moving blocks 24 by a screw, the two moving blocks 24 are respectively movably sleeved on the first transmission rod 18 and the second transmission rod 21, and a plug rod 25 is fixedly inserted into each moving block 24, one end of the two plug rods 25 is respectively slidably inserted into the first spiral groove 19 and the second straight groove 23;

[0031] The straightening structure includes a support plate 30 fastened to the base plate 1 by bolts. A second lifting frame 31 is set on the support plate 30 by an adjustment structure. L-shaped rods 32 are connected to both sides of the second lifting frame 31. The bottom end of the L-shaped rods 32 is connected to the top frame 33. Multiple rotating shafts 34 rotate through the top frame 33. A straightening roller 35 is fixedly sleeved on each rotating shaft 34.

[0032] The adjustment structure includes a through slot 37 on the support plate 30. The second lifting frame 31 is movably inserted into the through slot 37. An electric telescopic rod 36 is installed on the lower wall of the through slot 37. The top of the output shaft of the electric telescopic rod 36 is connected to the second lifting frame 31. First, according to the actual needs, the electric telescopic rod 36 is activated to drive the second lifting frame 31 to move vertically on the support plate 30 to flexibly adjust the height of the straightening roller 35. Then, the aluminum flat tube to be straightened is placed on the material support plate 6 on the right. Then, the electric push rod 27 in the groove 29 is activated, which drives the U-shaped plate 26 to move to the left in the base plate 1 through the push block 28. The U-shaped plate 26 drives the right moving block 2 to move to the right. The bottom end of the upper insertion rod 25 slides in the first spiral groove 19 on the first transmission rod 18. The insertion rod 25 presses against the wall of the first spiral groove 19, causing the first transmission rod 18 to rotate. Since one end of the first transmission rod 18 is connected to the right screw 3, the right screw 3 rotates, causing the right moving seat 4 to move to the left on the base plate 1. Simultaneously, the U-shaped plate 26 drives the bottom end of the upper insertion rod 25 on the left moving block 24 to slide in the second straight groove 23 on the second transmission rod 21. The left screw 3 remains stationary, and as the right moving seat 4 moves, it drives the first driving rod 11 on the right lifting plate 8 to slide in the first driving groove 13 of the horizontal plate 12. The first driving rod 11 drives the right lifting plate 8 to move up and down on the corresponding support frame 5, thereby driving the clamping plate 10 on the right first lifting frame 9 to move down, thus clamping and fixing one end of the aluminum flat tube on the right support plate 6. Then, the right moving seat 4 continues to move, driving the aluminum flat tube to the straightening roller 35 on the top frame 33 for straightening. As the U-shaped plate 26 continues to move, the other end of the aluminum flat tube is inserted into the left support plate 6, and the bottom end of the insertion rod 25 on the right moving block 24 slides into the first straight groove 20. The first transmission rod 18 stops rotating. During this process, the first driving rod 11 on the right lifting plate 8 slides into the second driving groove 15, thus... The right clamping plate 10 is moved upward to release the aluminum flat tube. Then, the U-shaped plate 26 continues to move, causing the bottom end of the insertion rod 25 on the left moving block 24 to slide into the second spiral groove 22, thereby driving the second transmission rod 21 and the left screw 3 to rotate as a whole. This causes the left moving seat 4 to move to the left on the base plate 1, and drives the second driving rod 14 to slide in the second driving groove 15, thereby driving the left clamping plate 10 to move downward. The other end of the aluminum flat tube is clamped on the left material support plate 6 and continues to move and straighten. By alternately clamping both ends of the aluminum flat tube, the aluminum flat tube is better exposed for straightening, making the straightening of the aluminum flat tube more thorough and improving the straightening efficiency.

[0033] See Figures 4-7The anti-deformation structure includes a first through plate 38 that moves through the horizontal plate 12, and a second through plate 39 that moves through the horizontal plate 12 below the first through plate 38. A first support plate 40 is connected to the left side of both first through plates 38, and a second support plate 42 is provided on the right side of the second through plate 39. An anti-deformation plate 41 is supported between the two first support plates 40. Two sets of support grooves 43 are provided on the anti-deformation plate 41. One end of the first support plate 40 is movably inserted into one set of support grooves 43. A second driving structure is provided between the first through plate 38, the second through plate 39 and the movable seat 4 on the right.

[0034] The second driving structure includes a third driving groove 16 formed on the first through plate 38, a fourth driving groove 46 formed on the second through plate 39, a T-shaped plate 44 connected to the right-side movable seat 4, and two third driving rods 45 connected to the T-shaped plate 44. Each third driving rod 45 moves through the corresponding third driving groove 16 and fourth driving groove 46. During the clamping movement, the aluminum flat tube is fitted onto the anti-deformation plate 41. The anti-deformation plate 41 supports the inner wall of the aluminum flat tube, preventing deformation of the inner wall during straightening. During the process, the right-side moving seat 4 drives the third driving rod 45 on the T-shaped plate 44 to press the wall of the fourth driving groove 46, pushing one end of the two second support plates 42 into another set of support grooves 43 on the anti-deformation plate 41. As the right-side moving seat 4 continues to move, it drives the third driving rod 45 to press the wall of the third driving groove 16, pushing the first support plate 40 out of one set of support grooves 43 on the anti-deformation plate 41. Through the automatic intermittent support of the anti-deformation plate 41, the aluminum flat tube can move smoothly on the anti-deformation plate 41, ensuring the normal progress of the straightening work.

[0035] The implementation principle of a straightening device for processing aluminum flat tubes according to an embodiment of the present invention is as follows: First, according to the actual needs, the electric telescopic rod 36 is activated to drive the second lifting frame 31 to move vertically on the support plate 30 to flexibly adjust the height of the straightening roller 35. Then, the aluminum flat tube to be straightened is placed on the right-side support plate 6. Next, the electric push rod 27 in the groove 29 is activated, which drives the U-shaped plate 26 to move to the left in the base plate 1 through the push block 28. The U-shaped plate 26 drives the bottom end of the insertion rod 25 on the right-side moving block 24 to slide in the first spiral groove 19 on the first transmission rod 18. Through the compression of the groove wall of the first spiral groove 19 by the insertion rod 25, the first transmission rod 18 is pushed to rotate. Since one end of the first transmission rod 18 is connected to the screw 3 on the right side, The right screw 3 rotates, causing the right movable seat 4 to move to the left on the base plate 1. Simultaneously, the U-shaped plate 26 drives the bottom end of the insertion rod 25 on the left movable block 24 to slide in the second straight groove 23 on the second transmission rod 21. The left screw 3 remains stationary, and as the right movable seat 4 moves, it drives the first driving rod 11 on the right lifting plate 8 to slide in the first driving groove 13 of the horizontal plate 12. This, in turn, drives the right lifting plate 8 to move up and down on the corresponding support frame 5 via the first driving rod 11, causing the clamping plate 10 on the right first lifting frame 9 to move down, thus clamping and fixing one end of the aluminum flat tube on the right support plate 6. Then, the right movable seat 4 continues to move, moving the aluminum flat tube to the straightening roller 35 on the top frame 33 for straightening. As the U-shaped plate 26 rotates, the right movable seat 4 moves to the left, causing the right movable seat 4 to move to the straightening roller 35 on the top frame 33 for straightening. As plate 26 continues to move, the other end of the aluminum flat tube is inserted into the left support plate 6. The bottom end of the insertion rod 25 on the right moving block 24 slides into the first straight groove 20, and the first transmission rod 18 stops rotating. During this process, the first driving rod 11 on the right lifting plate 8 slides into the second driving groove 15, thereby causing the right clamping plate 10 to move upward and release the aluminum flat tube. Then, U-shaped plate 26 continues to move, causing the bottom end of the insertion rod 25 on the left moving block 24 to slide into the second spiral groove 22, thereby causing the second transmission rod 21 and the left screw 3 to rotate as a whole. This causes the left moving seat 4 to move to the left on the base plate 1, and causes the second driving rod 14 to slide in the second driving groove 15, thereby causing the left clamping plate 10 to move downward and clamp the aluminum flat tube on the left support plate 6. The other end continues to move and straighten. By alternately clamping both ends of the aluminum flat tube, the tube is better exposed for straightening, resulting in a more thorough straightening process and improved efficiency. As the aluminum flat tube moves while being clamped, it is fitted onto the anti-deformation plate 41. The anti-deformation plate 41 supports the inner wall of the aluminum flat tube, preventing deformation during straightening. While the aluminum flat tube is on the anti-deformation plate 41, the right-side moving seat 4 drives the third driving rod 45 on the T-shaped plate 44 to press against the wall of the fourth driving groove 46, pushing one end of each of the two second support plates 42 into another set of support grooves 43 on the anti-deformation plate 41. As the right-side moving seat 4 continues to move, the third driving rod 45 presses against the wall of the third driving groove 16.The first support plate 40 is pushed out from one of the support slots 43 on the anti-deformation plate 41. Through automatic intermittent support of the anti-deformation plate 41, the aluminum flat tube can move smoothly on the anti-deformation plate 41, ensuring the normal progress of the straightening work. This achieves the straightening of the aluminum flat tube.

[0036] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
