Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 , 3 As shown in Figures 5-7, a sheet metal bending device for processing the outer shell of an automobile charging pile is provided according to an embodiment of the present invention. It includes a base 2 and a processing table 4. The processing table 4 is fixed above the base 2 by support columns 3. A support 1 is provided on the lower side of the base 2. The number of support columns 1 and 3 can be arranged as needed and is not limited. The support columns 3 can stably support the processing table 4, and the support 1 can support the entire device. It also includes:

[0030] A bending support mechanism is provided, comprising a bending support cylinder 15 and a third telescopic component 17. Multiple bending support cylinders 15 are installed on the processing table 4 in sequence. A third telescopic component 17 is fixedly installed on the lower side of the bending support cylinder 15. The lower end of the third telescopic component 17 is fixed on the machine base 2. The third telescopic component 17 is used to control the lifting and lowering of the bending support cylinder 15, thereby providing support for the bending support cylinder 15 when bending sheet metal 6.

[0031] A forward bending mechanism is mounted on a bending support mechanism. The forward bending mechanism is used to cooperate with the bending support mechanism so that the sheet metal 6 is bent along the surface of the bending support cylinder 15.

[0032] A reverse bending mechanism is installed on the forward bending mechanism. The reverse bending mechanism is used to cooperate with the forward bending mechanism so that the sheet metal 6 is bent along the surface of the forward bending mechanism.

[0033] In this embodiment of the invention, multiple bending support cylinders 15 are provided by the bending support mechanism. The extension of the corresponding bending support cylinder 15 is controlled by the third telescopic component 17, which allows for bending of the sheet metal 6 at different arcs. This matches the smooth process of modern car charging pile shells, reducing wind resistance and improving aesthetics. In addition, by limiting the forward bending mechanism, the forward bending mechanism cooperates with the bending support mechanism to allow the sheet metal 6 to bend along the surface of the bending support cylinder 15, achieving normal large arc bending of the sheet metal 6. By limiting the reverse bending mechanism, the reverse bending mechanism cooperates with the forward bending mechanism to allow the sheet metal 6 to bend along the surface of the forward bending mechanism. This allows for small arc bending of the sheet metal 6 as needed, and also allows for continuous bending of large and small arcs, such as large arc bending followed immediately by small arc reverse bending, thus improving the application range and effectiveness.

[0034] like Figure 1 , 3 As shown in Figure 7, in a preferred embodiment of the present invention, the bending support cylinder 15 is a cylindrical structure with open ends. The processing table 4 has an outlet 16 for mounting multiple bending support cylinders 15. The outermost bending support cylinder 15 is slidably connected to the outlet 16, and multiple bending support cylinders 15 are sequentially slidably connected. This allows the sheet metal 6 to be bent into different curvatures, thus having a wide range of applications. Furthermore, a third telescopic component 17 is fixedly installed on the lower side of each bending support cylinder 15. The number of the third telescopic components 17 is arranged as needed, sufficient to stably drive the bending support cylinder 15 to rise and fall. The lower end of the third telescopic component 17 is fixed to the machine base 2. When bending, only one bending support cylinder 15 needs to extend from the surface of the processing table 4. Preferably, the upper end face of the remaining bending support cylinders 15 is flush with the surface of the processing table 4. This facilitates the placement of the sheet metal 6 and reliable bending; specific details are not limited.

[0035] like Figure 1 , 3As shown in Figure 4, the forward bending mechanism includes a first bending column 7, a first connecting shaft 8, a first telescopic member 9, an outer cylinder 14, and a second gear and rack drive assembly 26. The outer cylinder 14 passes through the innermost bending support cylinder 15, and the outer cylinder 14 and the bending support cylinder 15 are arranged coaxially. The outer cylinder 14 is preferably slidably and rotatably connected to the innermost bending support cylinder 15, that is, the outer cylinder 14 can rotate and move relative to the bending support cylinder 15, without limitation. The first telescopic member 9 is fixedly installed on the upper end of the outer cylinder 14, and the first telescopic member 9 and the outer cylinder... The outer cylinder 14 is vertically arranged. A connecting shaft 8 is fixedly installed on the lower side of the telescopic spindle end of the first telescopic component 9. A bending column 7 is rotatably installed on the lower end of the connecting shaft 8. The bending column 7 has a cylindrical structure. The lower end of the outer cylinder 14 is rotatably connected to the base 2, which improves the stability of the outer cylinder 14. The thickness of the base 2 can be arranged as needed to ensure that the outer cylinder 14 has sufficient strength, without limitation. A second gear and rack drive assembly 26 for driving the rotation of the outer cylinder 14 is also installed on the lower side of the base 2. Depending on the selection of the bending support cylinder 15 and the thickness of the sheet metal 6, the position of the bending column 7 is controlled by the first telescopic component 9, and then... Figure 7 As shown, the outer cylinder 14 is controlled to rotate clockwise by the gear and rack drive assembly 26, so that the first bending column 7 rotates around the bending support cylinder 15. The sheet metal 6 can be bent and formed on the surface of the bending support cylinder 15 by the first bending column 7, which is stable, fast and has a good forming effect.

[0036] like Figure 1 , 3 As shown in Figure 4, the reverse bending mechanism includes a second telescopic member 10, a second connecting shaft 11, a second bending column 12, an inner shaft 13, and a first gear and rack drive assembly 25. The inner shaft 13 passes through the outer cylinder 14, and the outer cylinder 14 and the inner shaft 13 are arranged coaxially. The inner shaft 13 and the outer cylinder 14 are rotatably connected. The second connecting shaft 11 is fixedly installed on the upper end of the inner shaft 13. The second telescopic member 10 and the inner shaft 13 are arranged perpendicularly. The second telescopic member 10 is located on the upper side of the first telescopic member 9. The second connecting shaft 11 is fixedly installed on the lower side of the telescopic mandrel end of the second telescopic member 10. The second bending column 12 is rotatably installed on the lower end of the second connecting shaft 11. The second bending column 12 adopts a cylindrical structure. The first gear and rack drive assembly 25 for driving the inner shaft 13 to rotate is also installed on the lower side of the base 2. When reverse bending is required, the sheet metal 6 is first clamped and fixed by the cooperation of the first bending column 7 and the bending support cylinder 15. Then, the second bending column 12 is controlled to be positioned between the sheet metal 6 and the bending support cylinder 15 by the second telescopic component 10 and the first gear and rack drive assembly 25. Figure 7 As shown, by controlling the second bending column 12 to rotate counterclockwise through the first gear and rack drive assembly 25, the sheet metal 6 can be bent and formed along the first bending column 7.

[0037] In one embodiment, the first bending column 7 and the second bending column 12 have the same diameter. The lower end faces of the first bending column 7 and the second bending column 12 are spaced apart from the surface of the processing table 4. The first bending column 7 and the second bending column 12 are also parallel to the surface of the bending support cylinder 15. That is, the first bending column 7 and the second bending column 12 are both vertically arranged, which improves the quality of bending and forming of the sheet metal 6 by the first bending column 7 and the second bending column 12.

[0038] In one embodiment, the first gear and rack drive assembly 25 includes a second fixed base 27, an end seat 28, a fifth telescopic member 29, a second slide rail 30, a first connecting block 31, a first rack 32, and a first gear 33. The second slide rail 30 is located on the lower side of the base 2, and an end seat 28 is fixed to each end of the second slide rail 30. The end seats 28 are fixedly connected to the lower side of the base 2, providing stable support for the second slide rail 30. The first rack 32 is slidably mounted on the second slide rail 30. The inner shaft 13... The lower end is fixed with a first gear 33 that meshes with the first rack 32. A first connecting block 31 is fixed on the side of the first rack 32 away from the first gear 33. The fifth telescopic component 29 is fixed to the lower side of the machine base 2 through the second fixing seat 27. The telescopic spindle end of the fifth telescopic component 29 is fixedly connected to the first connecting block 31. The fifth telescopic component 29 is used to control the first rack 32 to move along the second slide rail 30. Through the meshing of the first rack 32 and the first gear 33, the inner shaft 13 can be driven to rotate.

[0039] In one embodiment, the second gear and rack drive assembly 26 includes a second gear 34, a second rack 35, a third slide rail 36, a third fixed base 37, a sixth telescopic member 38, and a second connecting block 39. The third slide rail 36 is fixed to the lower side of the machine base 2, and the second rack 35 is slidably mounted on the third slide rail 36. The lower end of the outer cylinder 14 is fixed with the second gear 34, which meshes with the second rack 35. The second connecting block 39 is fixed to the side of the second rack 35 away from the second gear 34. The sixth telescopic member 38 is fixed to the lower side of the machine base 2 through the third fixed base 37. The telescopic spindle end of the sixth telescopic member 38 is fixedly connected to the second connecting block 39. The sixth telescopic member 38 is used to control the movement of the second rack 35 along the third slide rail 36. Through the meshing of the second gear 34 and the second rack 35, the outer cylinder 14 can be driven to rotate.

[0040] like Figure 1-2As shown, in a preferred embodiment of the present invention, the processing table 4 is further fixed with a sheet metal fixing mechanism 5 for clamping and fixing the sheet metal 6. The sheet metal fixing mechanism 5 includes a fourth telescopic component 19, a first fixing seat 20, a fixing plate 21, a first slide block 22, a first fixing bolt 23, and a first slide rail 24. Two first slide rails 24 are fixed on the processing table 4. A first slide block 22 is slidably mounted on the first slide rail 24. The first slide block 22 is provided with a first fixing bolt 23 for locking it onto the first slide rail 24. The fixing bolt 23 is used to fix a first fixing seat 20 on the first slide block 22. A fourth telescopic component 19 is fixed on the first fixing seat 20. The fourth telescopic component 19 is preferably set perpendicular to the first slide rail 24. A fixing plate 21 is detachably fixed to one end of each of the two fourth telescopic components 19. The two fixing plates 21 cooperate to clamp and fix the sheet metal 6. The corner of the fixing plate 21 near the sheet metal 6 is preferably rounded to improve the clamping and fixing effect of the two fixing plates 21 on the sheet metal 6.

[0041] like Figure 8 and 9 As shown, in a preferred embodiment of the present invention, the sheet metal fixing mechanism 5 is further equipped with an auxiliary bending mechanism 40 for assisting in bending the sheet metal 6. The auxiliary bending mechanism 40 includes a bending plate 41, a fourth fixing seat 42, a seventh telescopic component 43, a second slide block 44, and a second fixing bolt 45. A second slide block 44 is slidably mounted on one of the first slide rails 24. The second slide block 44 is equipped with a second fixing bolt 45 for locking it onto the first slide rail 24. The second slide block 44 is also equipped with... A fourth fixing seat 42 is fixed, and a seventh telescopic component 43 is fixed on the fourth fixing seat 42. The seventh telescopic component 43 is preferably set perpendicular to the first slide rail 24. A bending plate 41 is detachably installed and fixed at the end of the telescopic spindle of the seventh telescopic component 43. When the sheet metal fixing mechanism 5 clamps and fixes the sheet metal 6, the seventh telescopic component 43 pushes the bending plate 41 to move, so that the sheet metal 6 can be bent. The fixing plate 21 and the bending plate 41 are detachable, which facilitates replacement as needed to form different shapes.

[0042] In this embodiment of the invention, when the auxiliary bending mechanism 40 is required for assisted forming, the auxiliary bending mechanism 40 can be installed on the sheet metal fixing mechanism 5. A suitable fixing plate 21 is selected to clamp the sheet metal 6, and then the auxiliary bending mechanism 40 is adjusted to a suitable position (mainly the position of the bending plate 41 relative to the fixing plate 21 is suitable), and locked with the second fixing bolt 45. Then, the bending plate 41 is extended by the seventh telescopic component 43 to push the sheet metal 6 to bend and form. The size of the rounded corner of the fixing plate 21 and the size and position of the bending plate 41 determine the formed shape, which can be flexibly adjusted as needed. By using the auxiliary bending mechanism 40 in combination with the bending support mechanism, the forward bending mechanism and the reverse bending mechanism, different shapes can be formed, thus improving the applicability.

[0043] like Figure 1-9 As shown, in a preferred embodiment of the present invention, the processing table 4 is also fixed with a control panel 18 for controlling various electrical components. The control, model and circuit connection of each electrical component are not specifically limited and can be flexibly set in actual application.

[0044] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.

[0045] Specifically, telescopic components 9, 10, 17, 19, 29, 38, and 43 are preferably made of hydraulic cylinders or electric telescopic cylinders, and the specific models are not limited or described in detail; slide rails 24, 30, and 36 are preferably made of T-shaped structure, and the slide blocks are arranged accordingly, which has the effect of preventing slippage and improving the reliability of the sliding connection.

[0046] The above embodiments of the present invention provide a sheet metal bending device for processing the outer shell of an automotive charging pile. This device can bend sheet metal 6 into arc shapes of different radii to match the forming of charging pile shells of different sizes. It also features forward large-arc bending and reverse small-arc bending, expanding the applicability of the bending process. Furthermore, it can perform continuous bending of large and small arcs by immediately following a large-arc bending. In addition, the combination of the sheet metal fixing mechanism 5 and the auxiliary bending mechanism 40 not only reliably clamps and fixes the sheet metal 6, but the sheet metal fixing mechanism 5 and the auxiliary bending mechanism 40 can also assist in bending the sheet metal 6, further enhancing the device's versatility.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
