Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending equipment technology, specifically to a sheet metal bending machine. Background Technology

[0002] In the sheet metal industry, bending machines are essential equipment for bending and forming workpieces. During the bending process, the sheet metal part is placed between upper and lower dies. The upper die is moved downwards under hydraulic or CNC control, bending the metal sheet. However, the bending angle varies depending on the requirements, and the depth of the resulting groove also differs. Existing sheet metal bending machines can only process sheet metal parts of a single mold type, resulting in limited applicability. Utility Model Content

[0003] The purpose of this invention is to design a sheet metal bending machine that allows for the replacement of the upper and lower dies when processing grooves of different depths, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal bending machine, including a frame, a drive mechanism mounted on the frame, a worktable mounted on the frame, and a lower die mechanism mounted on the worktable. The drive mechanism includes a first drive component, a connecting rod, and an upper die. The output end of the first drive component is connected to the connecting rod, and the connecting rod is detachably connected to the upper die. The lower die mechanism includes a fixed base, a movable plate, and a lower die. The fixed base is mounted on the worktable and located directly below the upper die. The fixed base and the movable plate are fixedly connected by a fastener, and the lower die is located between the fixed base and the movable plate.

[0005] Furthermore, both the fixed base and the movable plate are provided with multiple through holes, and the fastener includes multiple bolts, which pass through the through holes in the fixed base and the movable plate and are threadedly connected to the nuts.

[0006] Furthermore, the lower part of the connecting rod is provided with an external thread, and the upper mold is provided with an internal thread hole. The connecting rod and the upper mold are threadedly connected through the external thread and the internal thread hole.

[0007] Furthermore, the first drive assembly includes a hydraulic cylinder, the output end of which is connected to the connecting rod.

[0008] Furthermore, a limit assembly is installed on one side of the lower mold mechanism on the worktable.

[0009] Furthermore, the limiting component includes a second driving component, a fixing block, and a limiting plate. The second driving component is mounted on the worktable, the fixing block is mounted on the second driving component, and the limiting plate is mounted on the fixing block.

[0010] Furthermore, the second drive assembly includes slide rails respectively mounted on both sides of the worktable, the slide rails being slidably connected to the slider, and the fixing block being mounted on the slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention features a lower die mechanism that allows for the replacement of the upper and lower dies according to the required bending curvature and groove depth. Since the connecting rod is detachably connected to the upper die, the upper die can be replaced. Replacing the lower die simply requires loosening the fixing component. After replacement, the fixing component is used to secure the fixing seat, lower die, and movable plate together, thus fixing the lower die in place. This allows for the replacement of the upper and lower dies of the bending machine when processing different bending curvatures and groove depths, improving its applicability.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Example: Reference Figure 1-2 A sheet metal bending machine includes a frame 1, a drive mechanism mounted on the frame 1, a worktable 2 mounted on the frame 1, and a lower die mechanism mounted on the worktable 2. The drive mechanism includes a first drive assembly 3, a connecting rod 4, and an upper die 5. The first drive assembly 3 includes a hydraulic cylinder, the output end of which is connected to the connecting rod 4. The connecting rod 4 is detachably connected to the upper die 5. The hydraulic cylinder drives the connecting rod 4 and the lower die 8 to bend the sheet metal. The lower part of the connecting rod 4 has an external thread, and the upper die 5 has an internal threaded hole. The connecting rod 4 and the upper die 5 are threaded together through the external thread and the internal threaded hole. When replacing the upper die 5, it can be easily disassembled and installed by simply unscrewing the upper die 5. The lower die mechanism includes a fixed base 6, a movable plate 7, and a lower die 8. The fixed base 6 is mounted on the worktable 2 and located directly below the upper die 5. The fixed base 6 and the movable plate 7 are fixedly connected by a fixing member 9. The lower die 8 is located between the fixed base 6 and the movable plate 7. Depending on the required bending curvature and groove depth, the upper die 5 and lower die 8 are replaced. Since the connecting rod 4 is detachably connected to the upper die 5, the upper die 5 can be replaced. To replace the lower die 8, simply loosen the fixing piece 9. After replacement, the fixing piece 9 is used to fix the fixing seat 6, lower die 8, and movable plate 7 together, thus securing the lower die 8. This allows for the replacement of the upper and lower dies of the bending machine when processing different bending curvatures and groove depths, improving its applicability. Both the fixing seat 6 and movable plate 7 have multiple through holes. The fixing piece 9 includes multiple bolts 10, which pass through the through holes in the fixing seat 6 and movable plate 7 and are threaded to nuts 11. The number of bolts 10 installed at both ends of the lower die 8 and the spacing between the fixing seat 6 and movable plate 7 can be adjusted according to the length and width of the lower die 8, providing strong adaptability.

[0020] A limiting component 12 is installed on one side of the lower mold mechanism on the worktable 2. The limiting component 12 includes a second drive component, a fixing block 13, and a limiting plate 14. The second drive component is installed on the worktable 2 and includes slide rails 15 respectively installed on both sides of the worktable 2. The slide rails 15 are slidably connected to the slider. The fixing block 13 is installed on the slider, and the limiting plate 14 is installed on the fixing block 13. According to the bending position of the sheet metal, the distance between the limiting plate 14 and the lower mold 8 is adjusted by the sliding action of the slide rails 15 and the slide block. When the sheet metal is bent, only one end of the sheet metal needs to be directly against the limiting plate 14. This quickly positions the sheet metal on the lower mold 8, improving the efficiency of sheet metal bending.

[0021] The working principle of this embodiment is as follows: Based on the required bending angle and groove depth, the upper mold 5 and lower mold 8 are replaced. Since the connecting rod 4 and the upper mold 5 are threadedly connected, the replacement of the upper mold 5 can be completed simply by unscrewing and rescrewing it. The lower mold 8 is replaced by threading the bolt 10 through the through holes on the fixed seat 6 and the movable plate 7 and connecting it to the nut 11. Then, based on the bending position of the sheet metal, the distance between the limiting plate 14 and the lower mold 8 is adjusted under the sliding action of the slide rail 15 and the slide block. When bending the sheet metal, only one end of the sheet metal needs to be directly against the limiting plate 14. This is how it works.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
