[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] like Figure 1-2 As shown, the utility model provides a limiting assembly for bookend bending and forming, comprising a bottom plate 1, a fixing plate 3 is fixedly connected to one side of the top of the bottom plate 1, and a sliding groove 5 is opened on the other side of the top of the bottom plate 1, a positioning mechanism 2 is installed on the top of the bottom plate 1, and an adjustment mechanism 4 is installed on one side of the fixing plate 3;

[0025] The adjusting mechanism 4 includes a connecting block 42, one side of which is symmetrically connected to two elastic plates 48, and the connecting block 42 is fixedly connected to the fixing plate 3, a center rod 46 is installed between the two elastic plates 48, the top of the center rod 46 is rotatably connected to a wrench 44, the two elastic plates 48 are fixedly connected to locking teeth 43 on the opposite sides, the middle of the center rod 46 is rotatably connected to a bite block 47, one side of the elastic plate 48 is fixedly connected to a pointing plate 45, and the bottom of the pointing plate 45 is fixedly connected to a swinging plate 41.

[0026] A guide rod 412 is fixedly connected to the bottom of the swing plate 41 , and a rotating rod 411 is rotatably connected to one end of the swing plate 41 . The guide rod 412 is slidably connected to the sliding groove 5 , and the bottom of the rotating rod 411 is fixedly connected to the top of the bottom plate 1 .

[0027] The specific configuration and function of the present embodiment will be described in detail below. When the wrench 44 is pulled, its bottom end will abut against two flexible elastic plates 48. Since the elastic plates 48 are flexible, they will approach each other when subjected to pressure.

[0028] The locking teeth 43 between the two elastic plates 48 engage the bite block 47. This engagement effectively fixes the position of the pointing plate 45 and ensures the stability of the structure.

[0029] However, when the positions of the pointing plate 45 and the swing plate 41 need to be adjusted, the wrench 44 can be operated in the reverse direction. At this time, the elastic plate 48 will return to its original state and release the engagement with the bite block 47. In this way, the pointing plate 45 can drive the bite block 47 to rotate freely on the surface of the center rod 46, thereby adjusting the angle of the swing plate 41.

[0030] In the process of bending the material, the swing plate 41 plays a vital role. By controlling the swing plate 41 to rotate ninety degrees around the rotating rod 411, the material can be limited when the "L" shape is bent. This rotation action depends not only on the support of the rotating rod 411, but also on the sliding of the guide rod 412 in the sliding groove 5. The stable sliding of the guide rod 412 in the sliding groove 5 ensures the stability and accuracy of the swing plate 41 during the rotation process, thereby improving the stability and accuracy of the entire bending process.

[0031] In addition, the presence of the center rod 46 allows the positions of the pointing plate 45 and the swing plate 41 to be adjusted at will. This design not only improves the flexibility of operation, but also ensures that after multiple uses, the swing plate 41 can be easily adjusted to a suitable position to meet different bending requirements.

[0032] Embodiment 2

[0033] like Figure 3 and Figure 4As shown, the positioning mechanism 2 includes a second movable plate 27 and a first movable plate 21. A threaded rod 24 is rotatably connected to one side of the second movable plate 27. Both ends of the threaded rod 24 are threadedly connected to a lifting block 25. A baffle 28 is installed on one side of the lifting block 25. A sliding rod 23 is fixedly connected to one side of the first movable plate 21. One end of the sliding rod 23 passes through the fixed plate 3, and one end of the fixed plate 3 is fixedly connected to the second movable plate 27. A limiting hole 271 is provided on one side of the second movable plate 27, and the limiting hole 271 is slidably connected to the lifting block 25. Two hydraulic cylinders 22 are installed on one side of the fixed plate 3. The output end of the hydraulic cylinder 22 is fixedly connected to the first movable plate 21. A support rod 272 is fixedly connected to one side of the second movable plate 27, and the support rod 272 is slidably connected to the fixed plate 3. A positioning block 26 is slidably connected to the inner cavity of the lifting block 25, and a connecting rod 29 is fixedly connected to one side of the positioning block 26. One end of the connecting rod 29 is fixedly connected to the baffle 28 . A spring 291 is installed inside the lifting block 25 . One end of the spring 291 is fixedly connected to the baffle 28 .

[0034] The effect achieved by the whole embodiment is that, first, the raw material to be processed is placed between the fixed plate 3 and the second movable plate 27. Next, the hydraulic cylinder 22 is started to push the first movable plate 21 forward. At the same time, the four sliding rods 23 are pulled synchronously, which not only play the role of connection and force transmission, but also ensure the coordinated movement between the first movable plate 21 and the second movable plate 27. As the first movable plate 21 moves, the second movable plate 27 gradually approaches the fixed plate 3, and finally clamps the raw material tightly together with the fixed plate 3.

[0035] During the process of placing the raw materials, the support rods 272 can not only provide additional support force when the raw materials are placed to ensure the stability of the raw materials, but they can also slide relative to the fixed plate 3 to accommodate raw materials of different lengths and shapes.

[0036] After the raw material is clamped, the positioning operation begins. By rotating the threaded rod 24, we can use the opposite threads on the two ends of the threaded rod 24 to control the movement of the two lifting blocks 25. The lifting blocks 25 can be accurately moved to the desired position, and then the positioning blocks 26 are used to clamp and position the raw material. The role of the positioning blocks 26 is to further fix the position of the raw material to prevent sliding or offset during processing.

[0037] The use method and working principle of the device: When performing the bending process, the raw material is first placed between the fixed plate 3 and the second movable plate 27. Then, the first movable plate 21 is pushed to move by the drive of the hydraulic cylinder 22. In this process, the four sliding rods 23 will work together to pull the second movable plate 27 to move, so that the second movable plate 27 and the fixed plate 3 are closely matched, thereby firmly clamping the raw material. When placing the raw material, the support rod 272 will play a role in supporting the bottom end of the raw material, and in this process, the support rod 272 can also slide relative to the fixed plate 3 to adapt to raw materials of different sizes.

[0038] Next, by rotating the threaded rod 24, the two lifting blocks 25 can be controlled to move toward each other by utilizing the opposite thread characteristics of the two end surfaces. Subsequently, the positioning block 26 is used to clamp and position the raw material to further improve the positioning effect of the material. This not only plays a limiting role during processing, but also avoids sliding during the bending process, thereby ensuring the bending quality. When the positioning block 26 is combined with the fixed plate 3, the spring 291 will be squeezed through the connecting rod 29, and at the same time, the baffle 28 will be cooperated to ensure that the positioning block 26 will not be separated from the lifting block 25.

[0039] In addition, by pulling the wrench 44, the bottom end of the wrench 44 can be used to abut against the elastic plate 48, so that the two flexible elastic plates 48 are close to each other. In this way, the locking teeth 43 between the two elastic plates 48 can engage the bite block 47, thereby fixing the pointing plate 45. Conversely, if the position of the pointing plate 45 needs to be adjusted, the wrench 44 can be reversed to restore the elastic plate 48 to its original state, so that the pointing plate 45 can drive the bite block 47 to rotate on the surface of the center rod 46, thereby adjusting the angle of the swing plate 41.

[0040] During the bending operation, the swing plate 41 is controlled to rotate ninety degrees around the rotating rod 411, and the guide rod 412 is used to slide inside the sliding groove 5, so that the stability of the swing plate 41 during sliding can be ensured. In this way, the limiting effect of the swing plate 41 can ensure that the material can form an accurate "L" shape when being bent and formed.

[0041] Through the center rod 46, we can adjust the position of the pointing plate 45 and the swing plate 41 at any time. This not only improves the flexibility of operation, but also ensures that after multiple uses, the swing plate 41 can be easily adjusted to a suitable position to meet different processing requirements.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
