Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, specifically to a sheet metal bending device. Background Technology

[0002] A sheet metal bending machine is a machine capable of bending thin sheets of metal, and is one of the important pieces of equipment in the sheet metal industry for bending and forming thin sheet parts. The basic principle of sheet metal bending is to use the plastic deformation of metal to manufacture parts or components of the required shape and size. During the bending process, the metal sheet undergoes a series of bending, forming, and welding processes to gradually form the required shape and size.

[0003] Currently, when bending long strips of sheet metal, due to their considerable length, workers need to manually rotate the sheet metal at a large angle to adjust its position to the appropriate bending area when bending its edges. This large rotation angle increases the difficulty and physical exertion of the workers. At the same time, manually pushing long strips of sheet metal poses significant safety hazards. Operators may cause accidents due to improper force or loss of control of the sheet metal, resulting in personal injury and poor consistency in bending angles. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a sheet metal bending device that eliminates the need for manual pushing of the sheet metal to rotate at large angles, reducing operational difficulty and physical exertion, while also avoiding the safety hazards associated with manual pushing, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a sheet metal bending device, comprising a bending device body, a flipping plate rotatably connected to the outer side of the bending device body, an extension plate fixedly connected to the outer side of the bending device body, a hinge seat fixedly connected to the upper side of the extension plate, an mounting plate rotatably connected to the inner side of the hinge seat, a first hydraulic cylinder fixedly connected to the outer side of the mounting plate, a connecting block fixedly connected to the output end of the first hydraulic cylinder, the outer side of the connecting block hinged to the outer side of the flipping plate, an adjustment component provided on the outer side of the flipping plate, an abutment plate provided on the upper side of the flipping plate, a second hydraulic cylinder fixedly embedded in the upper side of the bending device body, a pressure seat fixedly connected to the output end of the second hydraulic cylinder, and a pressing module fixedly installed on the bottom side of the pressure seat.

[0006] The above solution, by setting up a flip plate, extension plate, hinge seat, mounting plate, first hydraulic cylinder and connecting block, allows the first hydraulic cylinder to drive the flip plate to rotate when the end edge of a long strip of sheet metal needs to be bent. This eliminates the need for workers to manually push the sheet metal to rotate a large angle, reducing the difficulty of operation and physical exertion. It also avoids the safety hazards caused by manual pushing. In addition, the adjustable components control the lateral position of the abutment plate to adapt to sheet metal of different sizes, further improving the practicality of the equipment.

[0007] Furthermore, the adjustment assembly includes two fixing blocks fixedly connected to the bottom surface of the flip plate. The inner sides of the two fixing blocks are rotatably connected to lead screws, and the outer sides of the lead screws are threadedly connected to a movable frame. The outer side of the movable frame is fixedly connected to the outer side of the abutment plate.

[0008] Through the above solution, the fixed block, lead screw, and moving frame can move the moving frame by rotating the lead screw, thereby adjusting the position of the abutment plate to adapt to long strip sheet metal of different sizes, improving the versatility of the equipment, and enabling precise adjustment of the sheet metal position, which helps to ensure the consistency of bending angle.

[0009] Furthermore, two symmetrical guide grooves are provided on the outer side of the flip plate, and the outer side of the movable frame is slidably connected to the inner side of the pointer.

[0010] The above solution, by setting the guide groove, allows the outer side of the moving frame to slide and connect to the inner side of the guide groove, providing guidance for the movement of the moving frame and ensuring the stability of the abutment plate during movement. This further ensures the positional accuracy of the sheet metal during bending and improves the bending quality.

[0011] Furthermore, a connecting shaft is rotatably connected to the inner side of one of the fixing blocks, and one end of the connecting shaft is fixedly connected to one end of the lead screw. A locking component is provided on the outer side of the connecting shaft, and a rotating handle is fixedly connected to the other end of the connecting shaft. Anti-slip texture is provided on the outer side of the rotating handle.

[0012] Through the above scheme, the cooperation between the rotating handle and the locking assembly allows for convenient adjustment of the abutment plate position. The locking assembly locks the connecting shaft, preventing the lead screw from rotating during processing and ensuring the fixed position of the abutment plate, thus providing a guarantee for stable bending.

[0013] Furthermore, the locking assembly includes a fixing plate fixedly connected to the outside of the flip plate, a threaded rod threadedly connected to the inner side of the fixing plate, a clamping block rotatably connected to one end of the threaded rod, and a hexagonal block fixedly connected to the other end of the threaded rod.

[0014] The above solution utilizes the combined action of a fixed plate, threaded rod, clamping block, and hexagonal block. Rotating the hexagonal block moves the threaded rod, causing the clamping block to press against the connecting shaft, thus achieving rapid locking and unlocking of the connecting shaft. The operation is simple and the locking effect is reliable.

[0015] Furthermore, the inner arc surface of the clamping block is adapted to the shape of the threaded rod.

[0016] Through the above solution, the clamping block can increase the contact area with the connecting shaft, improve the stability and reliability of locking, and prevent the connecting shaft from loosening during processing.

[0017] Furthermore, a pointer is fixedly connected to one end of the abutment plate, and a scale is fixedly connected to the upper side of the flip plate.

[0018] With the above solution, by setting up a pointer and a ruler, the staff can intuitively observe the movement distance of the abutment plate, thereby adjusting the position of the abutment plate more accurately, making it easier to control the bending dimensions of the sheet metal and ensuring the consistency of the bending angle.

[0019] Furthermore, two symmetrical guide rods are fixedly connected to the inner side of the bending equipment body, and the inner side of the pressure seat is slidably connected to the outer side of the guide rods.

[0020] The above solution, by setting the guide rod, provides guidance and support for the up and down movement of the press base, ensuring the stability and verticality of the pressing module when pressing down on the sheet metal, and improving the bending accuracy and quality of the sheet metal.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This sheet metal bending equipment, by setting up a flipping plate, an extension plate, a hinge seat, a mounting plate, a first hydraulic cylinder, and a connecting block, allows the first hydraulic cylinder to drive the flipping plate to rotate when bending the end edge of a long strip of sheet metal. This eliminates the need for workers to manually push the sheet metal to rotate a large angle, reducing the difficulty of operation and physical exertion, while also avoiding the safety hazards caused by manual pushing. At the same time, the adjustment component controls the lateral position of the abutment plate to adapt to sheet metal of different sizes. Combined with pointers and scales, it achieves visual positioning, significantly improving bending accuracy. Attached Figure Description

A first hydraulic cylinder 8 is fixedly connected to the outer side of the mounting plate 7. A connecting block 9 is fixedly connected to the output end of the first hydraulic cylinder 8. The outer side of the connecting block 9 is hinged to the outer side of the flipping plate 2. The first hydraulic cylinder 8 drives the flipping plate 2 to rotate through the connecting block 9, eliminating the need for workers to manually push the sheet metal to rotate a large angle, reducing the difficulty of operation and physical exertion, and avoiding the safety hazards caused by manual pushing. An adjustment component 4 is provided on the outer side of the flipping plate 2. The adjustment component 4 controls the lateral position of the abutment plate 10 to adapt to sheet metal of different sizes, further improving the practicality of the device. An abutment plate 10 is provided on the upper side of the flipping plate 2. A pointer 12 is fixedly connected to one end of the bending plate 10, and a scale 13 is fixedly connected to the upper side of the flip plate 2. By setting the pointer 12 and the scale 13 to cooperate, the operator can intuitively observe the moving distance of the abutment plate 10, thereby adjusting the position of the abutment plate 10 more accurately, which is convenient for controlling the bending size of the sheet metal and ensuring the consistency of the bending angle. A second hydraulic cylinder 14 is fixedly embedded on the upper side of the bending equipment body 1. A pressure seat 15 is fixedly connected to the output end of the second hydraulic cylinder 14. A pressing module 16 is fixedly installed on the bottom side of the pressure seat 15. Two symmetrical guide rods 17 are fixedly connected to the inner side of the bending equipment body 1. The inner side of the pressure seat 15 is slidably connected to the outer side of the guide rods 17. By setting the function of the guide rods 17, the pressing seat 15 can be guided and supported for the up and down movement of the pressure seat 15, ensuring the stability and verticality of the pressing module 16 when pressing down on the sheet metal, and improving the bending accuracy and quality of the sheet metal.

[0026] Please see Figure 1 , Figure 2 and Figure 4The adjustment assembly 4 includes two fixing blocks 401 fixedly connected to the bottom surface of the flip plate 2. A lead screw 402 is rotatably connected to the inner side of the two fixing blocks 401, and a movable frame 403 is threadedly connected to the outer side of the lead screw 402. The outer side of the movable frame 403 is fixedly connected to the outer side of the abutment plate 10. The fixing blocks 401, lead screw 402, and movable frame 403 can be adjusted by rotating the lead screw 402 to move the movable frame 403, thereby adjusting the position of the abutment plate 10 to accommodate long strip sheet metal of different sizes, improving the versatility of the equipment. The sheet metal is stable and can be precisely adjusted to ensure consistent bending angles. The outer side of the flip plate 2 has two symmetrical guide grooves 11. The outer side of the moving frame 403 is slidably connected to the inner side of the pointer 12. By setting the guide grooves 11, the outer side of the moving frame 403 is slidably connected to the inner side of the guide grooves 11, which provides guidance for the movement of the moving frame 403 and ensures the stability of the abutment plate 10 during movement. This further ensures the positional accuracy of the sheet metal during bending and improves the bending quality.

[0027] Please see Figure 2 and Figure 5 One of the fixing blocks 401 has a connecting shaft 404 rotatably connected to its inner side, and one end of the connecting shaft 404 is fixedly connected to one end of the lead screw 402. A locking assembly 5 is provided on the outer side of the connecting shaft 404, and a rotating handle 405 is fixedly connected to the other end of the connecting shaft 404. The outer side of the rotating handle 405 is provided with anti-slip texture. The cooperation between the rotating handle 405 and the locking assembly 5 allows for easy adjustment of the position of the abutment plate 10. The locking assembly 5 locks the connecting shaft 404, preventing the lead screw 402 from rotating during processing, thus ensuring the fixed position of the abutment plate 10 and providing a guarantee for stable bending. The locking assembly 5 includes a fixing plate 501 fixedly connected to the outer side of the flipping plate 2, and the inner side of the fixing plate 501... The threaded connection includes a threaded rod 502, one end of which is rotatably connected to a clamping block 503, and the other end of which is fixedly connected to a hexagonal block 504. Through the coordinated action of the fixing plate 501, the threaded rod 502, the clamping block 503, and the hexagonal block 504, rotating the hexagonal block 504 drives the threaded rod 502 to move, causing the clamping block 503 to press against the connecting shaft 404, thus achieving quick locking and unlocking of the connecting shaft 404. The operation is simple and the locking effect is reliable. The inner arc surface of the clamping block 503 is adapted to the shape of the threaded rod 502. The clamping block 503 can increase the contact area with the connecting shaft 404, improve the stability and reliability of locking, and prevent the connecting shaft 404 from loosening during processing.

[0028] This embodiment of a sheet metal bending device includes a flipping plate 2, an extension plate 3, a hinge seat 6, a mounting plate 7, a first hydraulic cylinder 8, and a connecting block 9. When it is necessary to bend the end edge of a long strip of sheet metal, the first hydraulic cylinder 8 drives the flipping plate 2 to rotate through the connecting block 9. This eliminates the need for workers to manually push the sheet metal to rotate a large angle, reducing the difficulty of operation and physical exertion. It also avoids the safety hazards caused by manual pushing. At the same time, the adjusting component 4 controls the lateral position of the abutment plate 10 to adapt to sheet metal of different sizes. Combined with the pointer 12 and the scale 13, it achieves visual positioning and significantly improves bending accuracy.

[0029] It should be noted that the anti-slip texture on the surface of the handle 405 increases the friction between the hand and the handle 405, making it less likely for the operator's hand to slip when turning the handle 405 to adjust the lead screw 402. This makes the operation more stable and effortless, and allows for more precise control of the rotation angle and number of turns of the lead screw 402.

[0030] The working principle of the above embodiment is as follows: According to the size of the long strip sheet metal, the screw 402 is rotated by rotating the handle 405, causing the moving frame 403 to move the abutment plate 10 under the guidance of the guide groove 11. By observing the position of the pointer 12 on the scale 13, the abutment plate 10 is adjusted to a suitable position. Then, the hexagonal block 504 is rotated to make the clamping block 503 press against the connecting shaft 404, locking the position of the abutment plate 10. Next, the long strip sheet metal is placed on the bending equipment body 1, and the long strip sheet metal... The end of the sheet metal is placed on the flipping plate 2, so that its end edge abuts against the abutment plate 10. Then, the second hydraulic cylinder 14 is activated, so that the press seat 15 drives the pressing module 16 to move downward under the guidance of the guide rod 17 to fix the sheet metal. Finally, the first hydraulic cylinder 8 is activated, and the flipping plate 2 is driven to rotate through the connecting block 9 to flip the end of the sheet metal, so that the sheet metal is bent. During this process, the abutment plate 10 always plays a role in positioning and supporting the sheet metal to ensure the consistency of the bending angle and the bending quality of the sheet metal.
