Description

Technical Field

[0001] This utility model relates to the technical field of cold bending production equipment, specifically a continuous cold bending production equipment for several types of steel frames used in greenhouses. Background Technology

[0002] A cold bending production line is a device used for cold bending and forming metal sheets. It gradually bends the metal sheet into the required shape and size through the rotation and pressing of a series of rollers. This device is widely used in construction, automotive, aerospace and other fields. It features high efficiency, precision and continuous production, and can meet the diverse needs of different industries for metal components. The core components of the cold bending production line include rollers, transmission system and control system.

[0003] The continuous cold bending production device for greenhouse steel frames is a cold bending equipment specifically designed for greenhouse construction. It can continuously and efficiently bend metal strips into steel frames. Through the precise pressing and rotation of multiple rollers, the metal strips are gradually formed into steel frames with a stable structure and high strength. Its unique continuous production method not only improves material utilization but also greatly accelerates the manufacturing speed of greenhouse frames, providing strong support for the rapid and large-scale construction of modern greenhouses. The device is usually equipped with an advanced control system to ensure the accuracy and consistency of the production process, thereby meeting the stringent requirements of greenhouse construction for high-strength and durable frames.

[0004] However, existing continuous cold bending production devices for greenhouse steel frames, especially those using traditional fixed connection methods, require more time and manpower to change forming rollers, reducing production efficiency. Furthermore, these devices are difficult to adapt to the production of steel frames of different specifications, limiting production flexibility. Additionally, variables during the forming process are difficult to control, resulting in poor product consistency. Moreover, they lack an automatic pressure adjustment structure. To address these issues, a new continuous cold bending production device for greenhouse steel frames is proposed. 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] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 This utility model discloses a continuous cold bending production device for a type of steel frame for greenhouses, comprising two connecting frames 1. One end of one connecting frame 1 is fixedly connected to a servo motor 2, and the output end of the servo motor 2 passes through the connecting frame 1. The servo motor 2 allows the intermediate synchronous pulley 3 to rotate within the connecting frame 1. The other end of one connecting frame 1 is rotatably connected to evenly distributed synchronous pulleys 3, and the synchronous pulleys 3 are fixedly connected to the output end of the servo motor 2. A synchronous belt 4 is provided between adjacent synchronous pulleys 3. The presence of the synchronous belt 4 allows the adjacent synchronous pulleys 3 to rotate within the connecting frame 1, thereby driving the connecting rod 5 to rotate within the connecting frame 1.

[0034] Reference Figure 2 and Figure 3One end of each synchronous pulley 3 is fixedly connected to a connecting rod 5. One end of each connecting rod 5 is slidably connected to a forming roller 6. One end of each forming roller 6 is fixedly connected to a first spring 7. The other end of each first spring 7 is fixedly connected to a limit rod 8. One end of the connecting frame 1 at the other end has evenly distributed slots 9, and the slots 9 contact the limit rod 8. By allowing the limit rod 8 to slide into the forming roller 6, the first spring 7 is squeezed, thereby causing the forming roller 6 to slide out of the connecting rod 5, and thus the forming roller 6 can be removed. The top of each connecting frame 1 is fixedly connected to evenly distributed fixing rods 11, and the bottom of the outer ring of each fixing rod 11 is slidably connected to a fixed rod. Block 10, with the fixed block 10 penetrating through the slot 9, has an adjustment component in the middle of the outer ring of the fixed rod 11, and a cooling component at the bottom of the connecting frame 1. The adjustment component includes a second spring 12, which is sleeved in the middle of the outer ring of the fixed rod 11. The top of the outer ring of the fixed rod 11 is slidably connected to a pressure plate 14, and the top of the pressure plate 14 is rotatably connected to a threaded rod 13, which is threadedly connected to the connecting frame 1. By rotating the threaded rod 13, the fixed block 10 slides on the fixed rod 11, thereby compressing the second spring 12, thus providing precise control over the molding process and helping to produce a steel skeleton that meets quality requirements.

[0035] Reference Figure 4 The cooling component includes a support box 15, which is fixedly connected to the bottom of the connecting frame 1. A uniformly distributed ventilation duct 16 is connected through and fixedly to the top of the support box 15. A fan 17 is installed at the bottom of the inner wall of the ventilation duct 16, and a filter screen 18 is installed at the top of the inner wall of the ventilation duct 16. Driven by the fan 17, air is blown to cool the bottom of the raw material. A water pipe 19 is connected through and fixedly to one end of the support box 15, and a water tank 20 is connected through and fixedly to one end of the water pipe 19. A water pump 22 is fixedly connected to the outer wall of the water pipe 19, and the water pump 22 is fixedly connected to the water tank 20. One end of the water tank 20... The water pipe 19 is connected to a heat dissipation fin 21 through and fixedly connected to the end of the pipe. The water tank 20 installed can hold the required liquid and transport the liquid to the water pipe 19 through the water pump 22. At the same time, the heat dissipation fin 21 continuously cools the liquid stored in the water tank 20. Both ends of the outer wall of the water pipe 19 are connected to a transport pipe 23 through and fixedly connected to the ventilation duct 16. One end of the transport pipe 23 is fixedly connected to an atomizing nozzle 24. The atomizing nozzle 24 can spray the required liquid into the ventilation duct 16 in a mist form, and then transport it to the bottom of the raw material through the drive of the fan 17.

[0036] Working principle: By allowing the limiting rod 8 to slide into the forming roller 6, the first spring 7 is compressed. Then, the forming roller 6 slides into the connecting rod 5 at a designated position. Subsequently, the rebound of the first spring 7 causes the limiting rod 8 to slide out of the forming roller 6 and into the corresponding slot 9. Then, different forming rollers 6 are installed in designated positions according to a specified arrangement, operating synchronously. Then, the rotation of the threaded rod 13 on the fixing block 10 causes the threaded rod 13 to rotate on the connecting frame 1, causing the fixing block 10 to slide on the fixing rod 11, thus compressing the second spring 12. Finally, the upward sliding of the fixing block 10 compresses the second spring. 12 continues to compress, and then the second spring 12 rebounds, causing the fixed block 10 to reset, extruding and molding the raw material. Then, the water pump 22 drives the liquid in the water tank 20, which is continuously cooled by the heat dissipation fins 21, to the water pipe 19. Then, the liquid transported in the water pipe 19 is evenly distributed into each transport pipe 23 through multiple transport pipes 23. Then, the transported liquid is sprayed into the ventilation duct 16 in a mist form through the atomizing nozzle 24. At the same time, the fan 17 drives the gas and the mist cool liquid to move upwards, so as to contact the raw material. The filter screen 18 prevents external dust and other impurities from entering the ventilation duct 16.
