Abstract
Description
Technical Field
[0001] This application relates to the field of sheet metal bending technology, and in particular to a sheet metal component. Background Technology
[0002] Sheet metal bending is an important process in metal processing, widely used in many fields. In the machinery manufacturing industry, various machine housings, supports, and other components often require sheet metal bending to meet the structural requirements of different equipment. With technological advancements, the demands for precision, efficiency, and automation in sheet metal bending are constantly increasing. Traditional manual bending is gradually being replaced by advanced CNC bending equipment to meet the high-quality and high-efficiency needs of modern industrial production.
[0003] Existing sheet metal bending typically uses CNC bending machines. These machines mainly consist of a machine body, dies, hydraulic and control systems. The bending angle is adjusted by changing dies of different specifications. However, in terms of die installation, after installation, the vibration generated during bending can cause the fastening nuts to loosen over time, leading to die loosening. This loosening can then be pulled by the sheet metal, requiring recalibration of the cutting tools, which significantly reduces bending efficiency and quality. Summary of the Invention

[0008] In some embodiments, a limiting plate is pre-positioned in the movable groove through the adjustment port, the screw passes through the limiting plate, and the nut is located on the side of the limiting plate away from the meshing part. When the nut locks the sheet metal mold, the limiting plate stops the adjustment port on the inner wall near the meshing part.
[0009] In some embodiments, an elastic element is provided between the insertion portion and the bottom wall of the movable groove for elastic compression.
[0010] In some embodiments, the insertion part is further provided with a sliding hole on the side opposite to the engagement part, and a slide rod is slidably connected to the sliding hole. The elastic element is elastically compressed between the top wall of the sliding hole and one end of the slide rod, and the other end of the slide rod abuts against the bottom wall of the moving groove.

[0025] This application provides a sheet metal component 100, see reference. Figures 1 to 3 , Figure 1 This is a structural schematic diagram of an embodiment of the sheet metal component provided in this application. Figure 2 yes Figure 1 The diagram shows a structural schematic of a sheet metal assembly where the sheet metal mold is separated from the base. Figure 3 yes Figure 2 The diagram shows the separation structure of the base and the limiting block.
[0026] The sheet metal assembly 100 includes a base 10, multiple limiting blocks 20, and a sheet metal mold 30. The top surface of the base 10 has multiple moving slots 11 arranged in a row, and the sides of the base 10 have multiple adjusting ports 12 corresponding to and communicating with the moving slots 11. Each limiting block 20 includes an insertion part 21 and an engagement part 22 connected to one end of the insertion part 21. Each insertion part 21 is pre-connected to the corresponding moving slot 11, and each engagement part 22 is spaced apart from the top surface of the base 10. The sheet metal mold 30... The top of the sheet metal mold 30 has multiple bending grooves 31 for bending sheet metal. The bottom of the sheet metal mold 30 has a through T-shaped groove 32 with meshing teeth 33 inside. Each meshing part 22 passes through the T-shaped groove 32 and is provided with meshing teeth 33. Each meshing part 22 is provided with meshing teeth 33. The corresponding insertion part 21 is fastened by each adjustment port 12 so that each meshing part 22 meshes with the meshing teeth 33, thereby locking the sheet metal mold 30 on the base 10.
[0027] like Figure 2 As shown, the sheet metal mold 30 is separated from the base 10 and each limiting block 20. Each limiting block 20 is pre-connected to the corresponding moving groove 11 on the base 10 so that the T-shaped sliding groove 32 on the sheet metal mold 30 can pass through each limiting block 20, so that the sheet metal mold 30 is initially connected to each limiting block 20. Afterwards, the user tightens the corresponding limiting block 20 through each adjustment port 12, so that the meshing part 22 presses the inner wall of the T-shaped sliding groove 32 and meshes with the meshing teeth 33, thereby locking the sheet metal mold 30 on the base 10.
[0028] like Figure 2 and Figure 3 As shown, the top surface of the base 10 is provided with a plurality of movable slots 11 arranged in a row. The number of movable slots 11 can be 2, 3 or 4. Each movable slot 11 is provided with a corresponding limiting block 20. When the limiting block 20 is pre-connected to the movable slot 11, the limiting block 20 does not detach from the movable slot 11, and the limiting block 20 can move up and down relative to the movable slot 11, so that there is a sufficiently large space between the meshing part 22 and the top surface of the base 10, so that the T-shaped slide 32 can pass through each limiting block 20, thereby enabling the sheet metal mold to be installed extremely conveniently. The sheet metal mold 30 is installed on the base 10 and is locked to the base 10 by multiple limit blocks 20. The meshing part 22 of each limit block 20 presses and meshes with the meshing teeth 33 on the sheet metal mold 30, which can greatly enhance the firmness of the sheet metal mold 30 connected to the base 10. It can prevent the sheet metal mold 30 from being driven by the sheet metal during the bending process, which would cause the tool corresponding to the bending groove 31 to need to be recalibrated. It can greatly improve the installation firmness of the sheet metal mold 30 and avoid the adverse effects caused by the loosening of the sheet metal mold 30.
[0029] The top of the sheet metal mold 30 has multiple bending grooves 31, and the bending angle of each bending groove 31 can be different. Thus, the bending angle of each bending groove 31 can match different bending requirements, adapt to diverse sheet metal processing, and ensure bending accuracy and consistency.
[0030] Furthermore, since the number of bending grooves 31 distributed on a single sheet metal mold 30 is limited and cannot meet all bending requirements, multiple sheet metal molds 30 are designed, each with a different angle of bending groove 31. Users can select the appropriate sheet metal mold 30 for installation according to specific bending requirements to meet different bending needs.
[0031] In this embodiment, the T-shaped slide 32 includes a first slide 321 and a second slide 322 that are connected to each other. The first slide 321 and the second slide 322 are arranged in a T shape. The meshing part 22 is disposed in the first slide 321, and the insertion part 21 passes through the second slide 322. The bottom wall of the first slide 321 is provided with the second slide 322 and meshing teeth 33 located on both sides of the second slide 322. The meshing part 22 has teeth on the side facing the top surface of the base 10. The meshing part 22 is pressed against the bottom wall of the first slide 321 and the teeth mesh with the meshing teeth 22.
[0032] The T-shaped slide 32 passes through the sheet metal mold 30 in a direction parallel to the arrangement direction of the multiple moving slots 11. When each limiting block 20 is pre-connected to the base 10, the distance between each meshing part 22 and the top surface of the base 10 is greater than the depth of the second slide 322, ensuring that the T-shaped slide 32 is smoothly passed through each limiting block 20. Each plug part 21 is passed through the second slide 322 and the moving slot 11 respectively. At this time, the meshing part 22 has not yet meshed with the meshing tooth 33.
[0033] The depth of the first groove 321 is greater than the thickness of the engaging part 22, allowing the engaging part 22 to move along the depth of the first groove 321. When the sheet metal mold 30 is locked, the engaging part 22 moves downward within the first groove 321, gradually pressing against the bottom wall of the first groove 321. The teeth on the engaging part 22 also gradually engage tightly with the engaging teeth 33, ensuring the sheet metal mold 30 is firmly fixed and preventing displacement of the sheet metal mold 30 during processing, thereby effectively ensuring bending accuracy and processing efficiency.
[0034] In this embodiment, as Figure 3 As shown, the end of the insertion part 21 opposite to the engagement part 22 is connected to a screw 23. A nut 13 is pre-inserted into the moving groove 11 through the adjustment port 12. The screw 23 is pre-connected to the nut 23 in the moving groove 11. The corresponding nut 13 is adjusted through the adjustment port 12 so that the screw 23 drives the engagement part 22 to press against and engage with the engagement teeth 33, thereby locking the sheet metal mold 30.
[0035] Optionally, the size of the nut 13 is larger than the width of the moving groove 11 to prevent the nut 13 from coming out of the moving groove 11. By adjusting the nut 13 through the adjusting port 12, the meshing part 22 on the limiting block 20 can gradually mesh tightly with the meshing tooth 33, ensuring that the sheet metal mold 30 is firmly fixed and reducing the risk of the sheet metal mold 30 loosening during sheet metal bending.
[0036] In this embodiment, a limiting plate 14 is pre-installed in the moving groove 11 through the adjustment port 12. The screw 23 passes through the limiting plate 14 and is stopped in the moving groove 11 by the limiting plate 14. The nut 23 is located on the side of the limiting plate 14 away from the meshing part 22 and is screwed to the screw 23, thereby completing the pre-connection of the limiting block 20. When the nut 23 locks the sheet metal mold 30, the limiting plate 14 stops on the inner wall of the adjustment port 12 near the meshing part 22.
[0037] The limiting plate 14 acts as a gasket, which can effectively reduce the friction between the nut 23 and the moving groove 11 and reduce the damage to the inner wall of the moving groove 11. At the same time, it does not require limiting the dimensional relationship between the nut 13 and the moving groove 11, and can more reliably fix the sheet metal mold 30.
[0038] In this embodiment, the adjustment port 12 is a conical port, with the larger end of the conical port located on the side of the base 10. This allows the user to more easily adjust the nut 13 using tools through the conical port, thereby improving the efficiency of adjusting the nut 13.
[0039] Furthermore, an elastic element 24 is elastically compressed between the bottom wall of the insertion part 21 and the moving groove 11. The supporting force provided by the elastic element 24 can support the position of the limiting block 20 to remain stable during pre-connection, thereby facilitating the sequential passage of the T-shaped slide 32 of the sheet metal mold 30 onto each limiting block 20, and improving the assembly efficiency of the sheet metal mold 30 and each limiting block 20.
[0040] The elastic element 24 can be a tension spring, which is elastically compressed between the bottom end of the insertion part 21 and the bottom wall of the moving groove 11; or, the bottom end of the insertion part 21 and the bottom wall of the moving groove 11 are both provided with grooves, and the two ends of the elastic element 24 are respectively embedded in the grooves to ensure that the elastic element 24 stably supports the limiting block 20.
[0041] When the limiting block 20 is pre-connected to the base 11, the supporting force of the elastic element 24 keeps the position of the limiting block 20 stable and prevents it from falling due to gravity, thus facilitating the sequential insertion of the T-shaped slide groove 32 of the sheet metal mold 30 onto each limiting block 20. When the nut 13 is locked, the limiting block 20 can be driven to move downward and compress the elastic element 24. At the same time, the meshing part 22 of the limiting block 20 and the meshing tooth 33 are tightly engaged to stabilize the sheet metal mold 30 and ensure that it does not shift during bending.
[0042] Similarly, when the sheet metal mold 30 needs to be replaced, the nut 12 is loosened through the adjustment port 12. At the same time, under the support of the elastic element 24, the limit block 20 will gradually move upward, releasing the meshing relationship between the meshing part 22 and the meshing tooth 33, and allowing the sheet metal mold 30 to be removed from each limit block 20. Then, a new sheet metal mold 30 can be replaced.
[0043] In this embodiment, the side of the insertion part 21 away from the engagement part 22 is also provided with a sliding hole 210. The sliding hole 210 is slidably connected to a slide rod 25. An elastic member 24 is elastically compressed between the top wall of the sliding hole 210 and one end of the slide rod 25. The other end of the slide rod 25 abuts against the bottom wall of the moving groove 11.
[0044] The elastic element 24 indirectly abuts against the bottom wall of the moving groove 11 through the slide rod 25. The elastic element 24 is located in the sliding hole 210. The sliding hole 210 and the slide rod 25 are slidably engaged. Furthermore, the slide rod 25 also serves to guide the limiting block 20, ensuring that the limiting block 20 slides smoothly in the moving groove 11 and reducing friction and wear with the inner wall of the moving groove 11.
[0045] Specifically, the insertion part 21 is provided with two sliding holes 210 symmetrically about the screw 23. Each sliding hole 210 is provided with an elastic element 24 and a slide rod 25 to balance and support the limiting block 20, ensuring that the limiting block 20 can move in a balanced manner in the moving groove 11.
[0046] Unlike existing technologies, this application discloses a sheet metal assembly. By pre-connecting each limiting block to a base, a T-shaped groove on the sheet metal mold passes through the engaging portion of each limiting block. The T-shaped groove contains engaging teeth, and the engaging portion corresponds to these teeth. The limiting blocks are then tightened via an adjustment port, causing the insertion portion of the limiting block to move the engaging portion downwards. The engaging portion meshes with the engaging teeth and presses and locks the sheet metal mold onto the base. Utilizing the interlocking relationship between the engaging portion and the engaging teeth, the risk of loosening of the sheet metal mold during prolonged use can be effectively reduced, and the connection strength between the base and the sheet metal mold can be effectively improved.

Any equivalent structural or procedural transformations made based on the description and drawings of this application, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
