[0025] Embodiment

[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: an anti-rebound bending structure, including a bending platform 1, a mounting seat 2 is arranged on the top of the bending platform 1, a guiding column 3 is installed between the bending platform 1 and the mounting seat 2, a bending assembly is arranged on the guiding column 3, and a blanking assembly is arranged on the top of the bending platform 1.

[0027] By setting the bending component, the rebound of the product after bending can be offset, and the probability of product rebound can be reduced; the bending component includes a fixed seat 4, a bending plate 5 and a fixing plate 6. The fixed seat 4 is movably connected to the outside of the guide post 3. The bending plate 5 is fixedly connected to the bottom of the fixed seat 4. The fixing plate 6 is fixedly connected between the bending plates 5. A connecting column 7 movably penetrates through one side of the fixing plate 6. A tension spring 9 is movably sleeved on the outside of the connecting column 7 at the top side of the fixing plate 6. One end of the tension spring 9 is fixedly connected to the top of the fixing plate 6, and the other end of the tension spring 9 is fixedly connected to the outside of the connecting column 7. A pressing block 8 is arranged inside the bending plate 5 at the bottom end of the connecting column 7. A lower fixing block 11 is installed below the pressing block 8 at the top of the bending platform 1. A hydraulic cylinder 10 is installed on the top of the mounting seat 2. The piston rod of the hydraulic cylinder 10 is fixedly connected to the top of the fixed seat 4; by extending the piston rod of the hydraulic cylinder 10, the piston rod of the hydraulic cylinder 10 drives the fixed seat 4 to move downward on the outside of the guide post 3, so that the bending plate 5 abuts against the top of the plate. The bending plate 5 continues to move downward, and the two ends of the plate are bent by the bending plate 5. The lower fixing block 11 drives the deformed plate to move into the bending plate 5, and the bending of the plate can be completed.

[0028] In order to ensure the quality of product bending, inclined surfaces 12 are provided on both sides of the lower fixing block 11, and convex ribs 13 are provided on both sides of the top of the lower fixing block 11. By providing the inclined surfaces 12 on both sides of the lower fixing block 11, the two ends of the plate can be deformed inward to offset the product rebound force. At the same time, by providing the convex ribs 13 on the top of the lower fixing block 11, plastic deformation occurs at the root of the bent plate to reduce rebound.

[0029] By setting up the blanking component, the efficiency of sheet metal bending can be improved; the blanking component includes a support plate 15, a connecting rod 16 and a connecting block 17. The support plate 15 is fixedly connected to the rear side of the lower fixing block 11. The connecting rod 16 movably penetrates through one end of the support plate 15. The connecting block 17 is fixedly connected to one end of the connecting rod 16. A slot 18 is formed at the top of the connecting block 17. A U-shaped frame 19 is fixedly connected to one side of the connecting block 17. A telescopic spring 20 is movably sleeved on the outer side of the connecting rod 16. One end of the telescopic spring 20 is fixedly connected to the other side of the connecting block 17. The other end of the telescopic spring 20 is fixedly connected to one side of the support plate 15. A push post 14 is fixedly connected to one side of the fixing plate 6. One end of the push post 14 is located above the slot 18. The U-shaped frame 19 is located outside one end of the lower fixing block 11. When the sheet metal bending is completed, the hydraulic cylinder 10 drives the bending plate 5 to reset. The tension spring 9 pulls the pressing block 8 at one end of the connecting column 7 to abut against the upper part of the sheet metal, which is convenient for subsequent blanking. At the same time, the fixing plate 6 drives the push post 14 to move upward, so that one end of the push post 14 is separated from the slot 18 inside the connecting block 17. The telescopic spring 20 pushes the connecting rod 16 and the U-shaped frame 19 at one end of the connecting block 17 to reset, so that the U-shaped frame 19 pushes the bent sheet metal to move out of the outside of the lower fixing block 11, thus facilitating the removal of the bent sheet metal.

[0030] During the downward movement of the bending plate 5, the fixing plate 6 drives the push post 14 to move downward. One end of the push post 14 moves downward, so that one end of the push post 14 is inserted into the inside of the slot 18, thereby pushing the connecting block 17 to move, so that the connecting block 17 pushes the connecting rod 16 to move on the support plate 15. At this time, the telescopic spring 20 is compressed under force. At the same time, the U-shaped frame 19 is separated from the outside of the lower fixing block 11, avoiding interference with the bending of the sheet metal.

[0031] Working principle or structural principle, when bending the sheet metal, the piston rod of the hydraulic cylinder 10 extends. The piston rod of the hydraulic cylinder 10 drives the fixed seat 4 to move downward on the outside of the guide post 3, so that the bending plate 5 abuts against the top of the sheet metal. The bending plate 5 continues to move downward. The two ends of the sheet metal are bent by the bending plate 5. The lower fixing block 11 drives the deformed sheet metal to move into the inside of the bending plate 5. At this time, the connecting column 7 moves on the fixing plate 6. The tension spring 9 is in a stretched state. During this process, due to the inclined surfaces 12 provided on both sides of the lower fixing block 11, the two ends of the sheet metal can be deformed inward, offsetting the product rebound force. At the same time, the convex ribs 13 are provided on the top of the lower fixing block 11, causing plastic deformation at the root of the bent sheet metal and reducing the rebound.

[0032] During the downward movement of the bending plate 5, the push column 14 is driven to move downward by the fixing plate 6. One end of the push column 14 moves downward, so that one end of the push column 14 is inserted into the interior of the slot 18, thereby pushing the connecting block 17 to move, and enabling the connecting block 17 to push the connecting rod 16 to move on the support plate 15. At this time, the telescopic spring 20 is compressed under force, and at the same time, the U-shaped frame 19 disengages from the outside of the lower fixing block 11 to avoid interfering with the bending of the plate. After the plate is bent, the bending plate 5 is driven to reset by the hydraulic cylinder 10, and the tension spring 9 pulls the pressing block 8 at one end of the connecting column 7 to abut against the upper part of the plate, facilitating subsequent blanking. At the same time, the fixing plate 6 drives the push column 14 to move upward, so that one end of the push column 14 disengages from the slot 18 inside the connecting block 17, and the telescopic spring 20 pushes the connecting rod 16 and the U-shaped frame 19 at one end of the connecting block 17 to reset, enabling the U-shaped frame 19 to push the bent plate to move out of the outside of the lower fixing block 11, thereby facilitating the removal of the bent plate.
