Description

Technical Field

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

[0002] Sheet metal processing bending equipment is widely used in industries such as metal products, machinery manufacturing, and building decoration. Its main function is to bend or fold metal sheets along predetermined fold lines to meet the structural and appearance requirements of products.

[0003] Patent CN219233641U discloses a sheet metal folding device, including a placement plate. Two arc-shaped annular blocks are fixedly connected to the bottom surface of the placement plate. A first annular block and a second annular block are rotatably connected to the inner sidewalls of the two arc-shaped annular blocks, respectively. A fixing block and a scale are fixedly connected to the bottom surface of the placement plate, and the outer surface of the scale is rotatably connected to the first annular block. This patent utilizes the cooperation between a U-shaped block and a threaded rod to allow the U-shaped block to push the folding block to rotate around the arc-shaped annular blocks, thereby achieving the effect of folding the sheet metal at a certain angle. This solves the problem that most current sheet metal folding devices are stamping folding devices, directly folding the sheet metal to 90 degrees. When the required folding angle is not 90 degrees, the folding device cannot adjust the folding angle of the sheet metal according to the folding requirements.

[0004] As described above, most existing folding devices have fixed structures. When adapting to folding requirements of different specifications and shapes, it is necessary to replace the entire set of molds or folding mechanisms. This not only consumes a lot of time but also causes equipment downtime and reduces production efficiency. If damage occurs in some areas, it is often necessary to disassemble and repair the entire folding mechanism, increasing maintenance costs and time. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sheet metal folding device that solves the problem of needing to disassemble and repair the entire folding mechanism, which increases maintenance costs and time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal processing folding device, comprising:

[0007] A working base, the top of which is fixedly connected to a top worktable, and a material support platform is fixedly connected to one side of the top of the working base;

[0008] A pressure assembly, the top of which is fixedly connected to the bottom of the top worktable, is used to drive the folding device to move down to complete the folding;

[0009] The selection component is fixedly connected to one side of the top workbench surface and is used to select a specific sheet metal folding and pressing structure.

[0010] Preferably, the pressure assembly includes a hydraulic telescopic rod connected to the bottom of the top worktable, a bearing plate fixedly connected to the bottom end of the hydraulic telescopic rod, a bearing frame fixedly connected to the bottom of the bearing plate, and a sliding groove plate fixedly connected to one side of the bearing plate.

[0011] Preferably, a guide plate is fixedly connected to one side of the inner wall of the top workbench, and the surface of the guide plate is adapted to the sliding groove plate.

[0012] Preferably, the selection component includes a stabilizing frame fixedly connected to one side of the top worktable. A track groove block is fixedly connected to one side of the bottom of the stabilizing frame. A sliding block is movably connected to the inner wall of the track groove block. An active punch is fixedly connected to one side of the sliding block. A threaded sleeve is fixedly connected to the top of the active punch. A linkage groove block is fixedly connected to the top of the active punch. A dovetail block is movably connected to the inner wall of the linkage groove block. A mounting plate is fixedly connected to the top of the dovetail block. A screw rod penetrates the surface of the mounting plate.

[0013] Preferably, a synchronization block is fixedly connected to one side of the pressure assembly.

[0014] Preferably, a stationary plate is fixedly connected to the surface of the active punch, a stationary screw is passed through the surface of the stationary plate, and a top plate is passed through the surface of the stationary screw.

[0015] This utility model provides a sheet metal processing folding device. Compared with the prior art, it has the following advantages:

[0016] 1. This sheet metal bending device allows for quick selection and replacement of different bending pressing structures through the selection of components. The operator can easily lock or remove the required pressing die using the screw rod and screw sleeve without replacing the entire bending mechanism. The sliding structure and dovetail connection ensure positioning accuracy during replacement while reducing replacement time. When different bending widths or shapes are required, only the corresponding modular punch needs to be activated or replaced, significantly improving the equipment's adaptability and maintenance convenience. It is particularly suitable for multi-variety, small-batch production modes, reducing downtime and lowering die inventory pressure.

[0017] 2. This sheet metal processing folding device features a pressure component with high load-bearing capacity and precise stroke control. The sliding groove plate and guide plate work together to further ensure smoothness and guiding accuracy during the pressing process. Compared to traditional mechanical cam or screw drives, hydraulic drive is more suitable for high-strength sheet metal processing. It can also quickly switch pressure parameters between sheets of different thicknesses and hardnesses, improving production flexibility and significantly reducing scrap rates caused by incompatible molds.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides two technical solutions:

[0025] Example 1: A sheet metal processing bending device, comprising:

[0026] The working base 1 has a top worktable 2 fixedly connected to its top and a material support platform 5 fixedly connected to one side of its top.

[0027] Pressure component 3, the top of pressure component 3 is fixedly connected to the bottom of top worktable 2, and pressure component 3 is used to drive the folding device to move down to complete the folding;

[0028] Select component 4, one side of which is fixedly connected to one side of the top worktable 2, is used to select a specific sheet metal folding and pressing structure. Select component 4 allows for quick selection and replacement of different folding and pressing structures. Through the cooperation of the screw rod and the screw sleeve, the operator can easily lock or remove the required pressing die without replacing the entire folding mechanism. The sliding structure and dovetail connection ensure positioning accuracy during replacement while reducing replacement time. When different folding widths or shapes are required, only the corresponding modular punch needs to be activated or replaced, significantly improving the adaptability and maintenance convenience of the equipment. It is particularly suitable for multi-variety, small-batch production modes, reducing downtime and lowering die inventory pressure.

[0029] Example 2 differs from Example 1 in that it is a sheet metal processing folding device. The pressure component 3 includes a hydraulic telescopic rod 31 attached to the bottom of the top worktable 2. The hydraulic telescopic rod is a precision hydraulic cylinder with a high-resolution displacement detection device (0.005mm resolution) and proportional servo control. It achieves a stroke adjustment accuracy of 0.01mm through closed-loop control. A bearing plate 32 is fixedly connected to the bottom of the hydraulic telescopic rod 31. A bearing frame 33 is fixedly connected to the bottom of the bearing plate 32. A sliding groove plate 34 is fixedly connected to one side of the bearing plate 32. A guide plate 35 is fixedly connected to one side of the inner wall of the top worktable 2. The surface of the guide plate 35 is adapted to the sliding groove plate 34.

[0030] Selectable component 4 includes a stabilizer 41 fixedly connected to one side of the top worktable 2. A track groove 42 is fixedly connected to one side of the bottom of the stabilizer 41. A sliding block 43 is movably connected to the inner wall of the track groove 42. An active punch 44 is fixedly connected to one side of the sliding block 43. A threaded sleeve 45 is fixedly connected to the top of the active punch 44. A linkage groove 46 is fixedly connected to the top of the active punch 44. A dovetail block 47 is movably connected to the inner wall of the linkage groove 46. The dovetail block 47 is adapted to the inner wall of the synchronization block 410. A mounting plate 48 is fixedly connected to the top of block 47. A screw rod 49 penetrates the surface of the mounting plate 48, and the screw rod 49 is compatible with the inner wall of the screw sleeve 45. A synchronizing block 410 is fixedly connected to one side of the pressure assembly 3. The surface of the synchronizing block 410 is provided with a synchronizing dovetail groove. A stationary plate 411 is fixedly connected to the surface of the active punch 44. A stationary screw 412 penetrates the surface of the stationary plate 411, and a top plate 413 penetrates the surface of the stationary screw 412. The pressure assembly 3 features high load-bearing capacity and precise stroke control. The hydraulic telescopic rod can achieve 0.01 mm-level adjustment of the downward stroke through the control system, ensuring high consistency of the folding angle and dimensions. The sliding groove plate 34 cooperates with the guide plate 35 to further ensure the smoothness and guiding accuracy of the downward pressing process. Compared with traditional mechanical cam or screw drive, hydraulic drive is more suitable for high-strength sheet metal processing. At the same time, it can quickly switch pressure parameters between plates of different thicknesses and hardnesses, improving the flexibility of production and significantly reducing the scrap rate caused by mold mismatch.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] During operation, the raw material is placed on the surface of the material support platform 5. The hydraulic telescopic rod 31 is activated, causing the support plate 32 and the support frame 33 to move downwards. The support frame 33 moves along the guide plate 35, simultaneously causing the synchronizing block 410 to move downwards, which in turn causes the active punch 44 to press down, completing the bending operation on the raw material. When the active punch 44 is fully loaded, for the active punch 44 in use, the stationary screw 412 on the surface of the stationary plate 411 is rotated to separate the stationary screw 412 from the top plate 413 and the stationary plate 411. Then, the active punch 44 is connected to the synchronizing block 410. For the active punch 44 that is not in use, it can be directly fixed to the top plate 413 by the stationary screw 412 to prevent it from shaking and falling off. During replacement and maintenance, rotate the screw rod 49 to separate it from the screw sleeve 45, and then from the mounting plate 48. Pull out the dovetail block 47 to separate it from the synchronizing block 410. After replacing the active punch 44, reverse the above steps. When the device is finished, restore it to its original state.
