Description

Technical Field

[0001] This utility model relates to the field of rain shelter greenhouse guide channel production technology, and in particular to a sheet metal bending device for the production of rain shelter greenhouse guide channels. Background Technology

[0002] Rain-sheltered greenhouse drainage channels are drainage structures installed on the top of greenhouses. They typically adopt a V-shaped or U-shaped design and are made of weather-resistant materials. Through a scientifically designed slope, they guide rainwater to flow quickly to pre-set drainage outlets, preventing rainwater from accumulating on the greenhouse top or dripping disorderly. This design can effectively prevent rainwater from washing away the soil and splashing mud to contaminate crops. At the same time, it reduces the risk of increased load on the greenhouse frame or corrosion caused by water accumulation. In areas with frequent rainfall, the drainage channels can also work with the drainage system to keep the inside of the greenhouse dry, creating a stable growing environment for seedlings or high-value crops.

[0003] Traditional sheet metal bending equipment relies mainly on simple mechanical limit devices when adjusting bending angles, lacking a precise feedback mechanism. There is often a deviation between the actual bending angle and the set value. This deviation accumulates during continuous production, resulting in inconsistent bending angles for the same batch of products. It can only provide a limited number of fixed angle positions and cannot achieve continuous stepless adjustment, making it difficult to meet the production needs of guide channels of different specifications. At the same time, sheet metal parts will vibrate and deform when subjected to large bending forces, which not only affects processing accuracy but also accelerates equipment wear and shortens its service life.

[0004] Therefore, in view of the problems that traditional sheet metal bending equipment has a simple structure, reduces production accuracy, makes it difficult to meet the production needs of guide channels of different specifications, and accelerates equipment wear and shortens service life, a sheet metal bending device that can perform high-precision angle adjustment can be designed for the production of guide channels for rain shelter greenhouses.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a sheet metal bending device for producing a rain-sheltered greenhouse guide channel, including a frame 1; it also includes fixed supports 2. Two fixed supports 2 are fixedly connected to both sides of the frame 1. An upper pressing component is rotatably connected to the fixed supports 2. An angle adjusting component is fixedly connected inside the frame 1. A first rotating rod 14 and a second rotating rod 15 are rotatably connected to the output end of the angle adjusting component. The angle adjusting component is used to push the first rotating rod 14 and the second rotating rod 15 to rotate. A lower pressure plate 17 is fixedly connected to the first rotating rod 14 and the second rotating rod 15. A third rotating rod 16 is rotatably connected to the bottom of the lower pressure plate 17. The third rotating rod 16 is fixedly connected to the frame 1. A first crank connecting rod 19 is rotatably connected to both ends of the first rotating rod 14. A third connecting rod 20 is rotatably connected to the other end of the first crank connecting rod 19. The other end of the third connecting rod 20 is rotatably connected to the frame 1. The second rotating rod 15 rotates at both ends. The device is dynamically connected to a second connecting rod 18, with the other end of the second connecting rod 18 rotatably connected to a second crank connecting rod 21. The other end of the second crank connecting rod 21 is rotatably connected to the frame 1. The first crank connecting rod 19 and the second crank connecting rod 21 are rotatably connected. The workpiece to be bent is placed on the frame 1. According to the required bending angle, the angle adjustment component outputs a certain power to the first rotating rod 14 and the second rotating rod 15. Because the first rotating rod 14 and the second rotating rod 15 are mounted on the lower pressure plate 17, the lower pressure plate 17 is subjected to pressure and rotates around the third rotating rod 16, changing the angle of the lower pressure plate 17. At the same time, the first crank connecting rod 19 and the second connecting rod 18 mounted on the first rotating rod 14 and the second rotating rod 15 rotate synchronously, driving the third connecting rod 20 and the second crank connecting rod 21 at the other end to rotate, providing stable support for the rotation of the lower pressure plate 17, making the device structure more complete.

[0024] Please see Figures 2-4In this embodiment, the pressing assembly includes a rotating support 301 rotatably connected to a fixed support 2. A first hydraulic cylinder 302 is fixedly connected to the rotating support 301, and a first hydraulic rod 303 is fixedly connected to the other end of the first hydraulic cylinder 302. The first hydraulic cylinder 302 is used to push the first hydraulic rod 303 to perform linear motion. A first connecting rod 4 is rotatably connected to the other end of the first hydraulic rod 303. The rotating support 301 is mounted on the fixed support 2, and the first hydraulic cylinder 302 outputs pressure to the first hydraulic rod 303, pushing the first hydraulic rod 303 to perform linear motion, so that the first hydraulic rod 303 pushes the first connecting rod 4 to rotate. The angle adjustment assembly includes a second hydraulic cylinder 1301 fixedly connected to the frame 1. A second hydraulic rod 1302 is fixedly connected to the output end of the second hydraulic cylinder 1301. The second hydraulic cylinder 1301 is used to push the second hydraulic rod 1302 to rotate. 2. The second hydraulic rod 1302 is fixedly connected to the connecting frame 1303 at the other end. The connecting frame 1303 is rotatably connected to the first rotating rod 14 and the second rotating rod 15. The second hydraulic cylinder 1301 outputs pressure to the second hydraulic rod 1302, pushing the second hydraulic rod 1302 to move linearly. The first rotating rod 14 and the second rotating rod 15 limit the movement of the connecting frame 1303, so that the second hydraulic rod 1302 drives the connecting frame 1303 to rotate. The end of the first connecting rod 4 away from the first hydraulic rod 303 is fixedly connected to the rotating shaft 5. The inner rings of the rotating bearings 6 are fixedly connected to both ends of the rotating shaft 5. The outer rings of the rotating bearings 6 are fixedly connected to the frame 1. When the first connecting rod 4 rotates, it drives the rotating shaft 5 to rotate. At the same time, the inner rings of the rotating bearings 6 cooperate with the rotating shaft 5 to rotate. Then, the outer rings of the rotating bearings 6 fix the rotating shaft 5 to the frame 1.

[0025] Please see Figures 2-5In this embodiment, two eccentric wheels 7 are fixedly connected to both sides of the rotating shaft 5. A circular ring sleeve 8 is fitted around the outer side of the eccentric wheels 7. A fixing post 9 is fixedly connected to the bottom of the circular ring sleeve 8. A mounting plate 10 is fixedly connected below the fixing post 9. When the rotating shaft 5 rotates, it drives the eccentric wheels 7 mounted on it to rotate. The eccentric wheels 7 control the change in distance between themselves and the center of the circular ring sleeve 8, thereby controlling the change in height of the fixing post 9. This causes the fixing post 9 to drive the mounting plate 10 to perform a linear reciprocating motion. Multiple clamping plates 11 are fixedly connected to the mounting plate 10. An upper pressure plate 12 is fixedly connected between the clamping plates 11 and the mounting plate 10. The multiple clamping plates 11 are used to... The upper pressure plate 12 is firmly fixed on the mounting plate 10, so that the mounting plate 10 drives the upper pressure plate 12 to move and complete the bending work of the sheet metal part. An angle sensor 22 is provided between the lower pressure plate 17 and the upper pressure plate 12. The angle sensor 22 is fixedly connected to the frame 1. The angle sensor 22 is electrically connected to the second hydraulic cylinder 1301. The angle sensor 22 detects the angle between the upper pressure plate 12 and the lower pressure plate 17 in real time. After analyzing and processing the detection results, the control signal is transmitted to the second hydraulic cylinder 1301 for adjustment. The model of the angle sensor 22 in this device is ZCT-CX05-RC01.

[0026] During operation, the workpiece to be bent is placed on the frame 1. Based on the required bending angle, the second hydraulic cylinder 1301 outputs pressure to the second hydraulic rod 1302, pushing it to move linearly. The first rotating rod 14 and the second rotating rod 15 limit the movement of the connecting frame 1303, causing the second hydraulic rod 1302 to rotate the connecting frame 1303. The connecting frame 1303 then pushes the lower pressure plate 17, causing it to rotate around the third rotating rod 16, changing its angle. Simultaneously, the first crank connecting rod 19 and the second connecting rod 18, mounted on the first rotating rod 14 and the second rotating rod 15, rotate synchronously, driving the third connecting rod 20 and the second crank connecting rod 21 at the other end to rotate, providing stable support for the rotation of the lower pressure plate 17. Then, multiple clamping plates 11 firmly fix the upper pressure plate 12 to the mounting plate 10. The first hydraulic cylinder... The pressure output by 302 is given to the first hydraulic rod 303, which pushes the first hydraulic rod 303 to move linearly, causing the first hydraulic rod 303 to drive the first connecting rod 4 to rotate. The first connecting rod 4 drives the rotating shaft 5 to rotate. At the same time, the inner ring of the rotating bearing 6 rotates in conjunction with the rotating shaft 5. Then, the outer ring of the rotating bearing 6 fixes the rotating shaft 5 to the frame 1. The rotating shaft 5 drives the eccentric wheel 7 mounted on it to rotate. The eccentric wheel 7 controls the change in the distance between itself and the center of the circular ring 8, thereby controlling the change in the height of the fixed column 9. This causes the fixed column 9 to drive the mounting plate 10 to move linearly back and forth. The mounting plate 10 drives the upper pressure plate 12 to move, completing the bending work of the sheet metal part. At the same time, the tilt sensor 22 detects the angle between the upper pressure plate 12 and the lower pressure plate 17 in real time. After analyzing and processing the detection results, the control signal is transmitted to the second hydraulic cylinder 1301 for adjustment to ensure the accuracy of the bending angle.

[0027] Through the above steps, using hydraulic drive and multiple linkage mechanisms, precise control of the bending angle is achieved, ensuring that the bending angle of each workpiece remains consistent even during continuous production. This completely avoids individual differences caused by frequent adjustments, ensures smooth drainage of rainwater, and prevents local water accumulation or poor drainage. It also provides additional stability support, effectively absorbing the reaction force generated by material springback, greatly reducing workpiece springback, significantly improving forming quality, effectively controlling scrap rate, and extending equipment lifespan. This solves the problems of traditional sheet metal bending equipment having a simple structure, reducing production precision, making it difficult to meet the production needs of different specifications of guide channels, and accelerating equipment wear and shortening its service life.
