[0026] Please refer to Figure 1 A kind of correction mechanism for porous microchannel aluminum flat tube, its structure is consistent with prior art device, mainly by force base 11, vertical correction component and horizontal correction component are constituted.
[0027] Force base 11 constitutes the basic part of correction mechanism, and vertical correction component and horizontal correction component are responsible for the correction task of aluminum flat tube 1 in vertical direction and horizontal direction respectively.
[0028] Referring to Figure 1 , Figure 2 The difference between the correction mechanism and prior art device lies in that vertical correction component is composed of two front and rear symmetrical correction members, and these correction members are responsible for the vertical correction of aluminum flat tube 1.
[0029] Horizontal correction component is composed of two upper and lower symmetrical correction members, and its function is to correct aluminum flat tube 1 in horizontal direction.
[0030] Specifically, each correction member contains a plurality of correction wheels 4, which are arranged in front and rear axial direction in vertical correction component and arranged in upper and lower axial direction in horizontal correction component. By adjusting the distance between the correction wheels 4 in the two correction members, the accurate correction of aluminum flat tube 1 is realized, and the aluminum flat tube 1 is ensured to be corrected to the predetermined state.
[0031] The correction wheels 4 are evenly distributed along the length direction of aluminum flat tube 1 to ensure that the length of the single correction member contacting with aluminum flat tube 1 is sufficient, so as to fully release the internal stress generated in the correction process of aluminum flat tube 1, promote the irreversible deformation of aluminum flat tube 1, and ensure the uniformity and accuracy of the correction effect.
[0032] In order to ensure the accurate and stable position of the plurality of correction wheels 4 in the correction member and prevent the position from being arbitrarily deviated, the device is particularly designed with a positioning plate 7 on one side of each correction member, and the positioning plate 7 is located at the axial end of the correction wheel 4.
[0033] By rotatingly connecting the positioning plate 7 with the corresponding correction wheel 4, it can be ensured that the relative position between the correction wheels 4 in the single correction member remains constant.
[0034] AsFigure 1 、 Figure 2 、 Figure 7 As shown, the correction wheel 4 is rotationally connected with the corresponding positioning plate 7 through a bearing, which further ensures the accuracy of the position of the correction wheel 4 and significantly reduces the resistance during the rotation of the correction wheel 4, effectively avoiding relative friction.
[0035] In addition, the rotationally connecting mechanism between the correction wheel 4 and the positioning plate 7 can also avoid unnecessary friction between the correction wheel 4 and the aluminum flat tube 1, thereby preventing damage to the aluminum flat tube 1 caused by excessive wear.
[0036] Further, as shown in Figure 1 、 Figure 2 To ensure that the width or longitudinal height of the deformed aluminum flat tube 1 does not exceed the distance between the two corresponding correction wheels 4 in the correction member, the device limits the distance between the left and right ends of the positioning plate 7 and the aluminum flat tube 1 to be inconsistent, which can meet the correction needs of aluminum flat tubes 1 of different widths.
[0037] Therefore, the plurality of correction wheels 4 arranged on each positioning plate 7 are uniformly arranged along the length direction of the positioning plate 7 to ensure uniform and consistent correction of the aluminum flat tube 1.
[0038] Specifically, as shown in Figure 7 Each positioning plate 7 is composed of an accommodation section and a correction section 702701. The distance between the correction section 702701 and the aluminum flat tube 1 remains constant to ensure the stability of the correction effect. The distance between the accommodation section and the aluminum flat tube 1 changes linearly along the length direction of the aluminum flat tube 1, which is designed to adapt to the bending condition of the aluminum flat tube 1 before correction.
[0039] At the same time, the distance between the correction section 702701 and the aluminum flat tube 1 is less than the distance between the accommodation section and the aluminum flat tube 1, so as to ensure that the correction section 702701 can effectively correct the aluminum flat tube 1. The correction section 702701 and the accommodation section are smoothly transitioned to avoid unnecessary damage to the aluminum flat tube 1 during the correction process.
[0040] Specifically, as shown in Figure 2 、 Figure 3 The device is adapted to aluminum flat tubes 1 of different sizes by adjusting the distance between the correction wheels 4 in the two correction members. The device is fixedly connected with a positioning shaft 8 on the side of the positioning plate 7 away from the corresponding correction wheel 4, and the center axis of the positioning shaft 8 is parallel to the center axis of the adjacent correction wheel 4.
[0041] In addition, the upper end of the force bearing base 11 is provided with an adjusting member 2, and a plurality of positioning shafts 8 are provided with sliding grooves 9 on the adjusting member 2. By limiting the positioning shaft 8 to be inserted into the sliding groove 9, and by utilizing the distance difference between the left and right ends of each sliding groove 9 and the aluminum flat tube 1, the distance between the two correction members in the vertical correction assembly and the horizontal correction assembly can be adjusted by sliding the adjusting member 2 left and right while keeping the positions of the two correction members unchanged, thereby achieving the technical effect.
[0042] In actual application, since the distance between the left end of the sliding groove 9 and the aluminum flat tube 1 is smaller than the distance between the right end and the aluminum flat tube 1, when the adjusting member 2 moves from left to right, the distance between the two correction members in the vertical correction assembly and the distance between the two correction members in the horizontal correction assembly will increase, at this time, the device can adapt to wider and thicker aluminum flat tubes 1. Correspondingly, when the adjusting member 2 moves from right to left, the device can adapt to narrower and thinner aluminum flat tubes 1.
[0043] Further, as shown in Figure 1 , Figure 2 , Figure 5 , the lower end limiting plate of the horizontal correction assembly is fixedly connected with a bolt I, and the adjusting plate is provided with a matching groove for the bolt I. By combining the matching groove with the bolt I, the adjusting plate can only move linearly left and right relative to the force bearing base 11, thereby ensuring that the correction member can accurately exert a correction effect on the aluminum flat tube 1 under the driving of the adjusting plate.
[0044] In addition, the cooperation of the bolt I and the nut I can effectively limit the adjusting plate, ensuring that the adjusting plate can only move linearly left and right on the force bearing base 11.
[0045] At the same time, it must be pointed out that, as shown in Figure 1 , Figure 2 , Figure 4 , the positioning shaft 8 of the horizontal correction assembly is in the shape of a screw rod, which cooperates with the corresponding nut II to fix the position between the positioning plate 7 and the adjusting plate, ensuring that the positioning shaft 8 is always embedded in the sliding groove 9 and constrained by the sliding groove 9.
[0046] The adjusting plate of the vertical correction assembly is clamped and fixed from the two axial ends of the correction wheel 4 of the vertical correction assembly, and the clamping action ensures that the position of the correction wheel 4 of the vertical correction assembly meets the expected requirements.
[0047] Specifically, to ensure the accurate position adjustment of the vertical correction assembly and the horizontal correction assembly, the device is provided with a limiting plate for each of the vertical correction assembly and the horizontal correction assembly at the upper end of the force bearing base 11, and a limiting slot 10 is formed in the limiting plate. By inserting each positioning shaft 8 into the corresponding limiting slot 10, the limiting slot 10 effectively restricts the position of the limiting plate 7, thereby achieving the purpose of accurately controlling the position of the vertical correction assembly and the horizontal correction assembly.
[0048] The limiting plate corresponding to the horizontal correction assembly is named limiting plate I 3, and the limiting plate corresponding to the vertical correction assembly is named limiting plate II 5.
[0049] In actual application, the length of the limiting slot 10 on the limiting plate I 3 in the left-right direction is equal to the diameter of the positioning shaft 8, and the width of the limiting slot 10 in the left-right direction is greater than the diameter of the positioning shaft 8. Such a design allows the corresponding limiting plate 7 of the horizontal correction assembly to move linearly in the left-right direction on the force bearing base 11, but cannot rotate in the left-right direction. Therefore, when the adjusting member 2 moves in the left-right direction, the distance between the two limiting plates 7 inside the horizontal correction assembly can be accurately controlled.
[0050] In actual application, the width of the limiting slot 10 on the limiting plate II 5 in the left-right direction is equal to the diameter of the positioning shaft 8, and the width of the limiting slot 10 in the up-down direction is greater than the diameter of the positioning shaft 8. Such a design allows the corresponding limiting plate 7 of the vertical correction assembly to move linearly in the up-down direction on the force bearing base 11, but cannot rotate in the left-right direction. Therefore, when the adjusting member 2 moves in the left-right direction, the distance between the two limiting plates 7 inside the vertical correction assembly can be accurately controlled.
[0051] In order to further expand the application range of the device and ensure that it can adapt to aluminum flat tubes 1 of special sizes, the constraint limiting plate I 3 and the force bearing base 11 are fixedly connected in the device. This design ensures that the horizontal correction assembly cannot move linearly in the transverse direction relative to the force bearing base 11, but can only move linearly in the longitudinal direction relative to the force bearing base 11 under the drive of the adjusting member 2.
[0052] Correspondingly, the limiting plate II 5 and the force bearing base 11 are slidingly connected. The use of this structure in combination with the adjusting member 2 allows the distance between the two correction members inside the vertical correction assembly to be accurately controlled by moving the vertical correction assembly left and right under the limitation of the sliding groove 9, while the position of the adjusting member 2 remains constant, i.e., the distance between the two correction members corresponding to the horizontal correction assembly remains unchanged.
[0053] Therefore, the limiting plate II 5 can move linearly in the left-right direction relative to the force bearing base 11 to meet the adaptability of the correction of aluminum flat tubes 1 of different sizes.
[0054] In detail, as shown in Figure 1 、 Figure 6 The limiting plate II 5 and the lower end of the adjusting member 2 are both configured with left and right axial lead screws 6. These lead screws 6 are connected with the force bearing base 11 in a rotating manner, and each lead screw 6 is connected with the corresponding limiting plate II 5 and the matching member through a thread. Through the adjustment of the lead screw 6, the position of the adjusting member 2 and the limiting plate II 5 can be accurately controlled, thereby realizing the fine correction of the aluminum flat tube 1.
[0055] In the actual application process of the utility model:
[0056] Firstly, the operator inserts the aluminum flat tube 1 from the right side between the two correction members of the vertical correction assembly, and at the same time, the driving mechanism and the cutting mechanism suitable for the processing process are configured and processed synchronously;
[0057] Then, the operator rotates the lead screws on the left and right sides, so that the adjusting member 2 and the limiting plate move linearly relative to the force bearing base 11, until the distance between the two correction members of the vertical correction assembly and the distance between the two correction members of the horizontal correction assembly reach the expected value, and the rotation of the lead screw 6 is stopped;
[0058] Subsequently, the operator starts the corresponding driving mechanism and cutting mechanism, and under the action of the driving mechanism, the aluminum flat tube 1 continuously moves to the left relative to the device;
[0059] Finally, when the aluminum flat tube 1 passes through the vertical correction assembly and the horizontal correction assembly, it is subjected to the compression action of the correction wheel 4, and the perpendicularity and flatness of the aluminum flat tube 1 are gradually adjusted to the expected state.
[0060] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
