The feeding and fixing of steel plates mostly rely on manual operation, which is not only time-consuming and labor-intensive, but also prone to displacement of steel plates during bending due to insecure fixing, affecting bending accuracy. The replacement process of bending rods is cumbersome and time-consuming, making it difficult to quickly adapt to the bending requirements of steel plates of different specifications. The equipment has poor versatility, which affects the improvement of production efficiency. Utility Model Content

[0031] 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.

[0032] Reference Figures 1-5This utility model provides an embodiment of a bending device for chassis processing, including a workbench 2, a conveyor belt 1 mounted on the top of the workbench 2, a bearing block 6 fixedly connected to the top of the workbench 2, a U-shaped frame 8 fixedly connected to the top of the workbench 2, a cylinder 13 fixedly connected to the inner top wall of the U-shaped frame 8, a fixed plate 14 fixedly connected to the output end of the cylinder 13, four fixed posts 12 fixedly connected to the bottom of the fixed plate 14, a fixed clamp 7 rotatably connected between two fixed posts 12 via a fixed rod 23, a cylinder 11 fixedly connected to the bottom of the fixed plate 14, a pressing plate 9 fixedly connected to the output end of the cylinder 11, and two fixed posts 5 fixedly connected to the top of the pressing plate 9 in a symmetrical distribution. Two support columns 10 are rotatably connected to the outer side. The end of the support column 10 away from the fixed pile 5 is rotatably connected to the inside of the fixed clamp 7. A steel plate 3 is set on the top of the conveyor belt 1. A cylinder 3 15 is fixedly connected to the inner top wall of the U-shaped frame 8. A fixed block 2 19 is fixedly connected to the output end of the cylinder 3 15. A fixed column 16 is slidably connected inside the fixed block 2 19. A bending rod 4 is fixedly connected to the bottom of the fixed column 16. A quick-release assembly is set inside the fixed block 2 19. The steel plate 3 is located between the two fixed clamps 7. The bottom of the pressing plate 9 abuts against the top of the steel plate 3. The bearing block 6 is located directly below the bending rod 4. The steel plate 3 is slidably connected to the top of the bearing block 6.

[0033] The workbench 2 serves as the basic support for the device, providing a stable processing environment. The conveyor belt 1 is responsible for horizontally transporting the steel plate 3 to be processed to the designated bending position. After bending, it is transported again, reducing the trouble of manual handling. The steel plate 3 is the processing object of the bending device. The bearing block 6 serves as the load-bearing support point for the steel plate 3. The U-shaped frame 8 is used to fix cylinder 13 and cylinder 35, ensuring the stability of cylinder 13 and cylinder 35 during operation, and also ensuring the stability of the components installed on it. Cylinder 13 serves as the power source, driving the fixed plate 14 to move up and down through telescopic movement, thereby controlling the clamping or releasing of the steel plate 3 by the fixing clamp 7. The fixing plate 14 is used to fix the support and rotation of the fixing clamp 7, while ensuring the relative position stability of these components during operation. The second fixing pile 12 is the rotation fulcrum of the fixing clamp 7, allowing the fixing clamp 7 to rotate around it, thereby achieving the clamping and fixing of the steel plate 3. The fixing clamp 7 is used to prevent the steel plate 3 from moving during the bending process. Cylinder 2 11 is used to assist the bending process. Cylinder 13 operates by pushing the pressing plate 9, which in turn drives the support column 10 to rotate, causing the two fixing clamps 7 to move closer together and fix the steel plate 3, preventing displacement during bending. Cylinder 13 is used to adjust the output force as needed to accommodate steel plates 3 of different thicknesses. The pressing plate 9 is used to make the steel plate 3 more stable during bending. Fixing post 5 serves as the rotation fulcrum for the support column 10, allowing the support column 10 to rotate flexibly. The support column 10 connects fixing post 5 and fixing clamps 7, playing a role in force transmission, thereby driving the fixing clamps 7 to clamp the steel plate 3. Cylinder 3 15 provides power for the bending operation. Fixing block 2 19 provides installation space for the quick-release components and is also the place to install the bending rod 4. Fixing post 16 is used to fix the bending rod 4, ensuring that the bending rod 4 does not shake during operation. The bending rod 4 is used to perform bending operations on the steel plate 3. Its shape and size are updated according to the bending requirements of the chassis. Different bending angles and shapes may require different bending rods 4.

[0034] Reference Figures 4-5 The quick-release assembly includes a protective shell 20, which is fixedly connected inside the fixing block 19. A pin 18 is slidably connected inside the protective shell 20. A spring 21 is sleeved on the outside of the pin 18. A pad 22 is fixedly connected to the outside of the pin 18. One end of the spring 21 is fixedly connected to one side of the pad 22, and the other end of the spring 21 abuts against the inner wall of the protective shell 20. The pad 22 is slidably connected inside the protective shell 20. A pull ring 17 is fixedly connected to the end of the pin 18 away from the pad 22. The pin 18 is inserted into the fixing post 16.

[0035] The protective shell 20 provides a closed and stable installation space for other parts of the quick-release assembly. The pin 18 is inserted into the fixing post 16 to fix the fixing post 16 and the fixing block 19, thereby completing the installation of the bending rod 4 and ensuring that the fixing post 16 and the bending rod 4 will not be displaced during the bending process. The spring 21 is in a compressed state in its natural state, which will generate a continuous pushing force on the pad 22, thereby pushing the pin 18 to remain inserted inside the fixing post 16, ensuring the reliability of the connection and preventing the pin 18 from accidentally coming off due to vibration or other reasons during the bending process. The pad 22 is used to transmit the elastic force of the spring 21 and to ensure that the pin 18 can slide smoothly inside the protective shell 20. The pull ring 17 is used to easily drive the pin 18 to slide inside the protective shell 20, realizing the separation of the pin 18 from the fixing post 16. The operation is simple and labor-saving, effectively improving the efficiency of replacing the bending rod 4.

[0036] Working principle: When the machine is being bent, the steel plate 3 to be processed is first placed on the conveyor belt 1. After the conveyor belt 1 is started, the steel plate 3 is horizontally transported to the bending processing area. Driven by the conveyor belt 1, the steel plate 3 will reach the top of the bearing block 6 and the bottom of the bending rod 4. When the steel plate 3 reaches the designated position, the cylinder 13 on the top wall of the U-shaped frame 8 is started, and its output end extends, driving the fixed plate 14 to move downward. The downward movement of the fixing plate 14 causes the bottom fixing pile 12, cylinder 11, and pressing plate 9 to move downwards synchronously. Simultaneously, the output end of cylinder 11 extends, pushing the pressing plate 9 downwards. The bottom of the pressing plate 9 abuts against the top of the steel plate 3, pressing and fixing the steel plate 3. As the pressing plate 9 moves downwards, it drives the support column 10 connected to the outside of the fixing pile 5 to rotate. Under the push of the support column 10, the fixing clamp 7 rotates around the fixing rod 23 between the two fixing piles 12. Since the steel plate 3 is located between the two fixing clamps 7, the two fixing clamps 7 rotate towards the center, clamping the steel plate 3 and preventing displacement of the steel plate 3 during bending. Then, the U-shaped... The output end of cylinder 15 on the inner top wall of frame 8 drives the fixed block 19 to move downward, thereby causing the fixed column 16 at the bottom of the fixed block 19 to move downward synchronously. Since the bearing block 6 is located directly below the bending rod 4 and the steel plate 3 is placed on top of the bearing block 6, the bending rod 4 will apply pressure to the steel plate 3 when it moves downward, causing the steel plate 3 to bend. Thus, the steel plate 3 completes the bending operation. After the bending is completed, the output end of cylinder 15 retracts and drives the bending rod 4 to return to its original position. Then, the output end of cylinder 11 retracts and drives the pressing plate 9 to move upward. Subsequently, the support column 10 pulls the fixing clamp 7 to rotate in the opposite direction and release the clamp on the steel plate 3, thus completing the release of the fixing of the steel plate 3.

[0037] When it is necessary to change the bending rod, pull the pull ring 17 to drive the pin 18 to slide inside the protective shell 20. The pin 18 disengages from the fixed post 16. Then, remove the fixed post 16 from the fixed block 19 to disassemble the bending rod 4. After replacing the bending rod 4, insert the corresponding fixed post 16 into the fixed block 19. Then, release the pull ring 17. Under the elastic force of the spring 21, the pin 18 automatically resets and is inserted into the fixed post 16, completing the installation and fixing of the bending rod 4, so as to carry out the bending processing of the next specification of steel plate 3.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
