Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and specifically relates to a metal sheet bending device. Background Technology

[0002] Metal sheet bending machines are core equipment in the metal sheet forming process. They bend metal sheets into different shapes according to the different specifications required by different industries. Most current metal sheet bending machines are mechanical levers and hydraulic drives, which require manual assistance during operation. This results in low efficiency and increases the risk of accidents for workers.

[0003] For example, a sheet metal bending device disclosed in announcement number CN214108364U includes a box body. Two support columns are fixedly connected to the inner wall of the box body. The top of the two support columns is fixedly connected to the same horizontal plate. Two fixed columns are symmetrically fixedly connected to the horizontal plate. The two fixed columns are slidably connected to the same short plate. A compression spring is fixedly connected to the top of the moving plate. A fixed plate is fixedly connected to the top of the compression spring. The fixed plate is slidably connected to a vertical rod. A sliding groove is opened on the vertical rod, and the sliding groove is above the fixed plate. This utility model does not require manual pushing during bending, and the clamping force of the machine pushing on the sheet metal is good, making it less likely for the sheet metal to shift.

[0004] However, during the operation of the aforementioned sheet metal bending device, the sheet metal will bend upwards at both ends due to the downward concavity in the middle. If the pressure of the upper die is too large, the fixed ends may also be subjected to large stress and deform or even crack. If the ends of the sheet metal are not fixed, the sheet metal will shift during bending, affecting the bending effect. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide a metal sheet bending device that eliminates the need for manual assistance and sheet fixing. The device uses support mechanisms on both sides to bend the sheet while providing support to prevent it from shifting during bending. It is particularly suitable for processing where the middle of the sheet needs to be bent.

[0006] The technical problem solved by this utility model can be achieved by the following technical solution: A metal sheet bending device includes a bending mechanism, a frame and a sheet. The bending mechanism includes an upper die, a moving component and a lower die. The upper die moves longitudinally through the moving component. It also includes support mechanisms located on both sides of the bending mechanism. The sheet is placed on the lower die and the upper part of the support mechanism. The support mechanism includes a first support frame, a second support frame and several lifting parts. Several hinge seats are provided on the frame. The first support frame and the second support frame are respectively hinged to the hinge seats. The lifting parts cause the first support frame and the second support frame to swing, thereby driving the sheet to bend.

[0007] The frame includes a base at the bottom and a frame at the top. The lower mold and support mechanism are located on the upper part of the base, and the moving components are located inside the frame.

[0008] The moving component includes a driving part and a sliding part. The sliding part includes a sliding boss and a sliding groove. Either the sliding boss or the sliding groove is located on the inner side of both sides of the frame, and the other is located on both sides of the upper mold. The driving part is used to drive the upper mold to move longitudinally along the sliding groove.

[0009] The upper mold includes a connecting part for connecting the movable component and a first shaping part located at the bottom, the first shaping part being any shape among cone, hemispherical, rectangular or serrated.

[0010] When the first and second support frames are not swinging upwards, the upper surface of the lower mold is at the same height as the upper surfaces of the first and second support frames.

[0011] The lower mold includes a second shaping part. The second shaping part is at the same height as the upper surfaces of the first support frame and the second support frame or forms a groove downwards. When the second shaping part forms a groove downwards, the shape of the second shaping part matches the shape of the first shaping part.

[0012] The lifting unit includes a cylinder. One end of a single lifting unit is installed in conjunction with a frame, and the other end is installed in conjunction with a first support frame or a second support frame.

[0013] The lifting unit includes a threaded screw. One end of the lifting unit is installed in conjunction with the frame, and the other end is installed in conjunction with the motor. A threaded screw nut is fitted on the screw. The screw nut is installed in conjunction with the first support frame or the second support frame. The motor drives the screw to rotate, so that the screw nut drives the first support frame or the second support frame to move along the screw, thereby realizing the swinging of the first support frame or the second support frame.

[0014] Compared with the prior art, this utility model has the following advantages: This utility model does not require manual operation or fixing of the plate. The plate is bent by the support mechanism on both sides, and the support mechanism provides support to prevent the plate from shifting during bending. It is especially suitable for processing processes that require bending the middle of the plate. When the support mechanism swings, it provides some force for bending the plate, which can reduce the squeezing force of the upper die on the plate to a certain extent and prevent surface damage or excessive deformation at the bending point of the plate.

[0019] Combined with appendix Figures 1 to 3 As shown, this embodiment discloses a metal sheet bending device, including a bending mechanism 1, a frame 3, and a sheet metal. The bending mechanism 1 includes an upper die 11, a moving component 12, and a lower die 13. The upper die 11 moves longitudinally through the moving component 12. It also includes support mechanisms 2 located on both sides of the bending mechanism 1. The sheet metal is placed on the lower die 13 and the upper part of the support mechanism 2. The support mechanism 2 includes a first support frame 21, a second support frame 22, and a plurality of lifting parts 23. The frame 3 is provided with a plurality of hinge seats 30. In this embodiment, the number of lifting parts 23 is 4. Two lifting parts 23 are provided on each side of the first support frame 21 and the second support frame 22. The number of hinge seats 30 is 2. Each hinge seat 30 includes two hinge pieces arranged opposite each other and a hinge groove located between the hinge pieces. The first support frame 21 and the second support frame 22 are hinged to the hinge seat 30 respectively. The lifting parts 23 cause the first support frame 21 and the second support frame 22 to swing, thereby driving the sheet metal to bend.

[0020] In this embodiment, based on the above installation structure, the end of the first support frame 21 is hinged to the hinge seat 30 in the hinge groove, and the end of the second support frame 22 is hinged to the outside of the hinge plate. In another embodiment, the hinge positions of the first support frame 21 and the second support frame 22 can be interchanged. In other embodiments, the ends of the first support frame 21 and the second support frame 22 can both be located in the hinge groove or on the outside of the hinge plate.

[0021] In combination with the above, the frame 3 includes a base 31 at the bottom and a frame 32 at the top. The lower mold 13 and the support mechanism 2 are located on the upper part of the base 31, and the moving component 12 is located inside the frame 32.

[0022] In conjunction with the above, the moving component 12 includes a driving part 121 and a sliding part 122. The sliding part 122 includes a sliding boss 1221 and a sliding groove 1222. Either the sliding boss 1221 or the sliding groove 1222 is located on the inner sides of both sides of the frame 32, and the other is located on both sides of the upper mold 11. The driving part 121 is used to drive the upper mold 11 to move longitudinally along the sliding groove 1222. In this embodiment, the sliding boss 1221 is located on the inner sides of both sides of the frame 32, and the sliding groove 1222 is located on both sides of the upper mold 11. The driving part 121 adopts a cylinder structure with a telescopic rod.

[0023] In conjunction with the above, the upper mold 11 includes a connecting portion 111 for connecting the moving component 12 and a first shaping portion 112 located at the lower part. The first shaping portion 112 is used to cut a bending notch on the sheet metal so that the sheet metal can be bent smoothly. The first shaping portion 112 adopts any shape among cone, hemispherical, rectangular or serrated. In this embodiment, the first shaping portion 112 adopts a cone shape with the cutting edge tilted downward. In other embodiments, other shapes commonly found in the prior art can also be adopted.

[0024] In summary, when the first support frame 21 and the second support frame 22 are not swinging upwards, the upper surface of the lower mold 13 is at the same height as the upper surfaces of the first support frame 21 and the second support frame 22, which facilitates the flat and stable placement of the plate.

[0025] In conjunction with the above, the lower mold 13 includes a second shaping part 131. The second shaping part 131 is at the same height as the upper surfaces of the first support frame 21 and the second support frame 22 or forms a groove downwards. When the second shaping part 131 forms a groove downwards, the shape of the second shaping part 131 matches the shape of the first shaping part 112. In this embodiment, the second shaping part 131 is at the same height as the upper surfaces of the first support frame 21 and the second support frame 22, that is, the surface of the lower mold 13 is flat.

[0026] In combination with the above, preferably, in this embodiment, the lifting part 23 includes a cylinder and a telescopic rod. One end of a single lifting part 23 is installed in conjunction with the frame 32, and the other end is installed in conjunction with the first support frame 21 or the second support frame 22. The cylinder drives the telescopic rod to extend and retract, thereby causing the first support frame 21 and the second support frame 22 to swing up and down, and causing the plate to bend.

[0027] In conjunction with the above, in another preferred embodiment, the lifting part 23 includes a threaded screw. One end of the lifting part 23 is installed in conjunction with the frame 32, and the other end is installed in conjunction with the motor. A threaded screw nut is fitted on the screw. The screw nut is installed in conjunction with the first support frame 21 or the second support frame 22. The motor drives the screw to rotate, so that the screw nut drives the first support frame 21 or the second support frame 22 to move along the screw, thereby realizing the up and down swing of the first support frame 21 or the second support frame 22 and driving the plate to bend.

[0028] This invention requires no manual operation or fixing of the sheet material. The sheet material is bent by the support mechanisms on both sides, which also provide support to prevent the sheet material from shifting during bending. It is especially suitable for processing that requires bending the middle of the sheet material. When the support mechanism swings, it provides some force for bending the sheet material, which can reduce the squeezing force of the upper die on the sheet material to a certain extent and prevent surface damage or excessive deformation at the bending point of the sheet material.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
