Description
Technical Field
[0001] The utility model relates to the field of sheet metal processing, and more specifically, to a buckled sheet metal device. Background Art
[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.
[0003] Bending is an important step in sheet metal parts, and its quality will significantly affect the quality of subsequent welding, splicing and forming. Many existing bending parts are done by bending machines in combination with manual labor, which is quite versatile. However, this method is labor-intensive and machine-intensive for small parts with large production quantities such as buckles, and the cost is relatively high.
[0004] Based on the above situation, the present application aims to provide a buckle sheet metal device. Summary of the invention
[0005] The utility model provides a buckle sheet metal device, which can improve the output of standard parts with huge single quantity and small specifications, reduce the occupation of manpower and machines, and reduce costs.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] The pressure block is used for bending, and the support block is used for positioning. This application is used to bend the buckle 180 degrees. For such a large-angle bending, at least two processes are required. This application uses the lifting of the first telescopic end to lift the sheet metal part on the premise of positioning the sheet metal part, thereby achieving the initial bending and producing a larger curvature; then the second bending is performed, and the pressure block is moved closer to the support block through the translation of the second telescopic end, thereby increasing the curvature of the sheet metal part to 180 degrees and completing the bending.
[0009] Preferably, a guide slot is provided on the first telescopic end, the second telescopic end is slidably connected to the guide slot, and the guiding direction of the guide slot is the length direction of the first telescopic end.
[0010] Preferably, a bending block is provided on the pressing block, and the bending block has a bending head in contact with the sheet metal, and the bottom surface of the bending head is higher than the top surface of the support block. When the second telescopic end moves toward the support block and reaches the stroke limit, the projection of the bending head coincides with the support block on a plane perpendicular to the top surface of the pressing block.
[0011] Preferably, during the bending process, the sheet metal part is in contact with the top surface of the support block.
[0012] Preferably, the edge line parallel to the sheet metal part and the bending head is provided with a chamfer so that adjacent surfaces on both sides of the edge line have a smooth transition.
[0013] Preferably, an anti-collision block is provided at one end of the pressing block away from the supporting block to prevent the pressing block from colliding with the second fixed end of the second telescopic structure.

[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] (1) The device is simple in form, requiring only two telescopic structures that can move independently to complete the sheet metal, and the cost of the device is low;
[0019] (2) The number of parts is small, and the pressing block and the supporting block are reused during the bending process, which reduces the volume and specifications of the device and is easy to assemble and maintain;

[0031] Example:
[0032] A buckle sheet metal device, Figure 1 , 2As shown, it includes a pressing block 3 and a supporting block 4, which are arranged on the first telescopic end 11 of the first telescopic structure 1 so that the pressing block 3 and the supporting block 4 can move synchronously, and the supporting block 4 is fixedly connected to the first telescopic end 11. The first telescopic end 11 is also provided with a second telescopic structure 2, and the pressing block 3 is fixedly connected to the second telescopic end 21 of the second telescopic structure 2. The pressing block 3 is configured to be able to approach or move away from the supporting block 4.
[0033] Among them, the first telescopic structure 1 and the second telescopic structure 2 are cylinders in some embodiments. Configuring them as oil cylinders or other linear motors does not violate the spirit of the present application, and the present application is not limited thereto.
[0034] Taking a cylinder as an example, the cylinder has a cylinder body and a telescopic shaft, and the two move relative to each other. The so-called fixed end and telescopic end in this application are set based on the reference system relative to the ground or sheet metal 10 when the mechanism actually moves. The fixed end is a component that is relatively stationary with respect to the reference system, and the telescopic end is a component that is relatively fixed with respect to the reference system. The first telescopic end 11 includes the telescopic shaft of the first telescopic structure 1 and a block, device and mechanism fixedly connected to the telescopic shaft and moving synchronously with the telescopic shaft. Similarly, the second telescopic end 21 includes the telescopic shaft of the second telescopic structure 2 and a block, device and mechanism fixedly connected to the telescopic shaft and moving synchronously with the telescopic shaft.
[0035] The first telescopic structure 1 has a guide shaft and a telescopic shaft. There are two guide shafts located on both sides of the telescopic shaft. The guide shaft slides on the first fixed end 12 (hereinafter referred to as the first fixed end 12) of the first telescopic structure 1 to provide smooth lifting and lowering of the first telescopic end 11 (hereinafter referred to as the first telescopic end 11) of the first telescopic structure 1.
[0036] The first telescopic end 11 includes the telescopic shaft of the first telescopic structure 1, a fixed plate and an L-shaped plate body fixedly connected thereto, the short side of the plate body is fixedly connected to the second telescopic mechanism, and has a through hole 71 for the telescopic shaft of the second telescopic mechanism to pass through. The plate body is fixedly connected to the guide slot 6 and the support block 4. The support block 4 is L-shaped, with its short side fixedly connected to the plate body, its long side arranged along the telescopic direction of the first telescopic end 11, and its top surface is a plane and perpendicular to the telescopic direction of the first telescopic end 11.
[0037] The first fixed end 12 is connected to the first sensing bracket 7. Along the height direction, two in-position sensors 9 are arranged on the first sensing bracket 7. The in-position sensors 9 are arranged at the preset travel limit positions corresponding to the first telescopic end 11. The first telescopic end 11 has a through hole 71 corresponding to the in-position sensor 9. The principle of the in-position sensor 9 to realize the in-position detection is that when it is directly opposite to the through hole 71, it sends a corresponding electrical signal to the controller to indicate that the first telescopic end 11 has reached the preset travel limit position and the first telescopic mechanism is stopped.
[0038] A second sensing bracket 8 is also fixedly connected to the plate body fixed to the second fixed end 22 (hereinafter referred to as the second fixed end 22) of the second telescopic mechanism. The second sensing bracket 8 has two in-place sensors 9 arranged along the length direction of the first telescopic end 11. The in-place sensors 9 are arranged at the preset stroke limit position corresponding to the second telescopic end 21. The pressing block 3 is fixedly connected to a corresponding sensing block 81. The sensing block 81 has two sensing heads 82. The two sensing heads 82 are arranged along the length direction. When any one of the sensing heads 82 is facing the in-place sensor 9, the in-place sensor 9 sends a signal to the controller indicating that the second telescopic end 21 (hereinafter referred to as the second telescopic end 21) of the second telescopic mechanism has reached the stroke limit position, and the second telescopic mechanism is stopped.
[0039] The preset stroke limit refers to the cylinder limit position set according to the bending requirements, rather than the maximum or minimum extension of the cylinder itself.
[0040] The second telescopic end 21 includes a telescopic shaft and a slider 5 fixedly connected to the telescopic shaft, and the slider 5 is slidably matched with the guide slot 6. The guide slot 6 is arranged along the length direction of the first telescopic block. The slider 5 is fixedly connected to the top block, and the slider 5 and the guide slot 6 cooperate to achieve the restriction and positioning of the pressing block 3.
[0041] The pressing block 3 is U-shaped, and an anti-collision block 34 is provided at the end away from the support block 4 to prevent the pressing block 3 from colliding with the second fixed end 22 of the second telescopic structure 2. A bending block 31 is fixedly connected to the end close to the support block 4. The bending block 31 has a bending head 32 in contact with the sheet metal 10. The bottom surface of the bending head 32 is higher than the top surface of the support block 4. When the second telescopic end 21 moves toward the support block 4 and reaches the stroke limit, the projection of the bending head 32 coincides with the support block 4 on the plane perpendicular to the top surface of the pressing block 3. Among them, the edge line parallel to the bending head 32 and the sheet metal 10 is provided with a chamfer 33 so that the adjacent surfaces on both sides of the edge line have a smooth transition. The method avoids damaging the sheet metal 10 during the bending process and keeps the sheet metal 10 intact. Among them, the closer the angle is to the contact of the sheet metal, the smaller the corresponding arc.
[0042] During the bending process, the sheet metal part 10 is in contact with the top surface of the support block 4 .
[0043] The pressing block 3 is used for bending, and the supporting block 4 is used for positioning. The present application is used to bend the buckle 180 degrees. For such a large-angle bending, at least two processes are required. The present application uses the lifting and lowering of the first telescopic end 11 to lift the sheet metal part 10 on the premise of positioning the sheet metal part 10, thereby achieving the initial bending and producing a larger curvature; then the second bending is performed, and the pressing block 3 is moved closer to the supporting block 4 through the translation of the second telescopic end 21, thereby increasing the curvature of the sheet metal part 10 to 180 degrees and completing the bending.
[0044] Ginseng Figures 3 to 6 As shown, the use process of this device is:
[0045] (1) Positioning the sheet metal part 10;
[0046] (2) Raise the first telescopic end 11 so that the top surface of the pressing block 3, which is higher than the support block 4, contacts the sheet metal part 10, and bend the sheet metal part 10 with the rounded corner of the bending head 32 as a fulcrum until the first telescopic end 11 reaches the preset travel limit, at which time the support block 4 fits the sheet metal part 10;
[0047] (3) The second telescopic end 21 extends, driving the pressing block 3 to approach the top block, and the bending angle of the sheet metal part 10 increases until it is pressed between the bending head 32 and the supporting block 4, completing the plastic deformation;
[0048] (4) The second telescopic mechanism and the first telescopic mechanism are reset in sequence, and the sheet metal part 10 is removed.
[0049] In the above process, the zero position of the device is when the first telescopic end 11 and the second telescopic end 21 are located closer to the in-position sensor 9 of the first fixed end 12 and the second fixed end 22 .
[0050] The bending head 32 has three rounded corners, which are used to contact the sheet metal 10 at different stages. The top rounded corner contacts the sheet metal 10 first, and is used to guide the sheet metal 10 to bend upward to form an arc. When the first telescopic end 11 reaches the stroke limit, part of the sheet metal 10 fits against the side wall of the bending head 32. The bending block 31 is L-shaped, and the bending head 32 is on the short side of the bending block 31. The rounded corner below the bending head 32 acts on the sheet metal 10 during the feeding process of the second telescopic end 21, prompting the sheet metal 10 to bend further, so that it gradually fits against the bottom surface of the bending head 32. The bending block 31 also has a rounded corner between the short side and the long side, which is used to finally shape the sheet metal 10, so that the sheet metal 10 is affected by the plasticity of the rounded corner, and a bending rounded corner corresponding to the rounded corner is generated.
[0051] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
