Description

Technical Field

[0001] The utility model relates to the technical field of bending devices, and specifically relates to a bending device for sheet metal processing. Background Technique

[0002] Under the pressure of a bending machine, a metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is freely bent. As the upper die or lower die presses on the sheet, the sheet gradually presses against the inner surface of the V-shaped groove of the lower die. Continuing to apply pressure until the stroke ends, the upper and lower dies and the sheet are in full contact at three points, completing a bending process. Bending is very common in mechanical production and is mostly used for right-angle bending of metal products.

[0003] Chinese Patent with publication number CN220920507U discloses a bending device for metal sheet processing. A cutter is horizontally arranged below the bottom surface of a fixed frame. One end of a hydraulic cylinder is fixedly connected to the top surface of the cutter. The cutter is located above the top of a bending groove and is vertically parallel to the bending groove. Chute grooves are respectively opened at both ends of the center position of the top surface of a workbench. A slide bar is horizontally arranged inside each chute groove. Limiting bars are movably arranged on both sides of the top surface of the workbench. The bottom of each group of limiting bars is movably fitted with the outer surface of the corresponding slide bar through a pipe sleeve to limit the position of each group of limiting bars. In this utility model, according to the bending angle requirement of the metal sheet, rotate the fixed plate to rotate the appropriate bending groove directly below the folding cutter, fix the working surface of the bending die through the fixed plate and the shaft rod, start the hydraulic cylinder, and push the cutter downward through the piston rod of the hydraulic cylinder to complete the bending of the metal sheet.

[0004] For the bending device for metal sheet processing involved in the above patent, it adjusts the sheet angle by rotating and selecting the bending groove on the bending die, but it can only adjust a limited angle, and the angle adjustment is not flexible enough. Therefore, we need to propose a bending device for sheet metal processing. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5, the utility model provides a sheet metal processing bending device, which includes a bottom plate 1. Above the bottom plate 1, there is a support plate 2. At the top of the support plate 2, two groups of side plates 3 are fixedly installed. Two groups of rollers 4 are rotatably installed between the two groups of side plates 3 which are distributed vertically. At the four corners of the bottom of the support plate 2, four support rods 23 are fixedly installed, and the bottom of the support rods 23 is fixedly connected to the top of the bottom plate 1. Through the setting of the support rods 23, the support plate 2 can be installed and fixed on the top of the bottom plate 1. Through the setting of the two groups of rollers 4, the sheet metal can be conveyed and positioned.

[0023] Preferably, a connecting plate 5 is fixedly installed on one side of the side plate 3. A rotating rod 6 is rotatably installed inside the two connecting plates 5. On one side of the rotating rod 6, an angle adjusting plate 7 is fixedly installed. Through the setting of the rotating rod 6, the angle adjusting plate 7 can be movably installed between the two connecting plates 5. Through the setting of the angle adjusting plate 7, the bending angle of the sheet metal can be adjusted.

[0024] Among them, on the top of the bottom plate 1, there is an angle adjusting component for adjusting the use angle of the angle adjusting plate 7. The angle adjusting component includes two groups of slide rails 8 fixedly installed on the top of the bottom plate 1. Inside the cavities of the two groups of slide rails 8, sliders 9 are slidably connected. There is a transmission component between the slider 9 and the angle adjusting plate 7. The transmission component includes a first hinge 10 fixedly installed on the top of the slider 9. On one side of the angle adjusting plate 7 and corresponding to the first hinge 10, a second hinge 11 is fixedly installed. An adjusting rod 12 is installed between the first hinge 10 and the second hinge 11.

[0025] Through the setting of the angle adjusting component, it is used to adjust the use angle of the angle adjusting plate 7. Specifically, when the user adjusts, the slider 9 can be slid inside the slide rail 8. The movement of the slider 9 will drive the angle adjusting plate 7 to rotate around the rotating rod 6 through the first hinge 10, the second hinge 11 and the adjusting rod 12, so as to adjust the use angle of the angle adjusting plate 7.

[0026] It should be noted that a limiting component is provided between the surface of the slider 9 and the inner wall of the slide rail 8. The limiting component includes limiting blocks 15 fixedly installed on both sides of the slider 9. On both sides of the inner cavity of the slide rail 8, limiting grooves 16 adapted to the limiting blocks 15 are opened. The surface of the limiting block 15 is slidably connected to the inner wall of the limiting groove 16. Through the setting of the limiting component, the slider 9 can be limited to prevent it from falling off the inner cavity of the slide rail 8. When the slider 9 moves, it will drive the limiting block 15 to slide inside the limiting groove 16.

[0027] Further, a locking component for fixing the usage position of the slider 9 is provided on the top of the slider 9. The locking component includes a locking tube 13 fixedly installed on the top of the slider 9. A locking rod 14 is threadedly connected to the top of the locking tube 13.

Through the setting of the locking component, after the usage angle of the angle adjustment plate 7 is adjusted, the user can tighten the locking rod 14 to lock and fix the usage position of the slider 9, and then fix the usage angle of the angle adjustment plate 7.

[0028] Furthermore, a bending component for bending the plate is installed on the top of the bottom plate 1 and corresponding to the angle adjustment plate 7. The bending component includes two fixed plates 17 fixedly installed on the top of the bottom plate 1. Electric sliding tables 18 are fixedly installed on the inner sides of the two fixed plates 17. A top plate 19 is fixedly installed on the moving end of the electric sliding table 18. The bottom of the top plate 19 is slidably connected to the top of the fixed plate 17. A lifting cylinder 20 is fixedly installed on the top of the top plate 19. The telescopic end of the lifting cylinder 20 penetrates through the top plate 19 and extends to the lower side of the top plate 19 to be fixedly installed with a connecting frame 21. A bending roller 22 is rotatably installed in the inner cavity of the connecting frame 21.

[0029] After the usage angle of the angle adjustment plate 7 is adjusted, the user can bend the plate through the bending component. Specifically, the user can drive the connecting frame 21 and the bending roller 22 to move downward through the lifting cylinder 20 to bend the plate. During the bending process, the electric sliding table 18 can drive the bending roller 22 to move, so that the bending roller 22 can move along the inclined direction of the angle adjustment plate 7 to bend the plate.
