Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and more specifically, to a bending device manufactured using vacuum equipment. Background Technology

[0002] Bending is a metal sheet forming process that applies external force to the sheet metal using pressure equipment and molds, causing it to undergo plastic deformation along a predetermined axis to form a specific angle or shape. This process utilizes the cooperation of upper and lower molds to concentrate stress in localized areas of the sheet metal, completing V-shaped, U-shaped, or polygonal bends. It is commonly used in sheet metal processing, machinery manufacturing, and the construction industry. Bending accuracy is affected by material properties (such as elastic modulus), mold design, equipment tonnage, and bending sequence. Its advantages lie in its high efficiency and flexibility, enabling the production of complex structural components such as chassis and brackets while maintaining material integrity and strength.

[0003] A search revealed that CN221362070U discloses a bending device for vacuum equipment manufacturing, which addresses the problem that "traditional bending machines require multiple extrusions and bends using bending rollers, which is cumbersome and time-consuming." The device uses a movable block that follows the movement of an arc-shaped rack to extrude and bend the unpressed portion of the sheet metal, pressing it against the outer wall of the pressing rollers to quickly create a welded pipe prototype. However, this device directly places the sheet metal on the bending groove for pressing and bending, lacking fixation or restraint. The sheet metal is prone to slippage or displacement during bending, leading to inaccurate bending line positions, poor finished product dimensions, or even scrap. Therefore, improvements are needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending device for manufacturing vacuum equipment, comprising a processing table, a fixed frame fixedly connected to the top of the processing table, a rectangular plate fixedly connected to the top of the fixed frame, a first motor fixedly connected to the front of the rectangular plate, a threaded rod fixedly sleeved at the other end of the output shaft of the first motor, the other end of the threaded rod penetrating the rectangular plate and extending into the interior of the rectangular plate and threadedly sleeved with a moving block, the bottom of the moving block being movably connected to the interior of the top of the fixed frame, a connecting rod hinged to the top of the moving block, a telescopic rod hinged to the other end of the connecting rod, and a pressure plate fixedly connected to the bottom end of the telescopic rod penetrating the fixed frame and extending into the inner cavity of the fixed frame.

[0006] As a preferred embodiment of this utility model, a soft pad is fixedly connected to the bottom of the pressure plate, and the soft pad is made of rubber.

[0007] As a preferred embodiment of this utility model, a pneumatic cylinder is fixedly connected to the top of the fixed frame, and the other end of the pneumatic cylinder passes through the fixed frame and extends into the inner cavity of the fixed frame and is fixedly connected to a bending head. A bending groove is fixedly installed inside the processing table, and the bending groove is located directly below the bending head.

[0008] As a preferred technical solution of this utility model, the left and right sides of the top of the bending head are fixedly connected with limit rods, and the top of the limit rods penetrates through the fixing frame and extends to the outside of the fixing frame.

[0009] As a preferred embodiment of this utility model, a second motor is fixedly connected to the left side of the bottom of the processing table, a rotating shaft is fixedly sleeved at the other end of the output shaft of the second motor, a rotating rod is fixedly sleeved at the other end of the rotating shaft, and sleeve rods are movably connected to both the front and rear sides of the outer surface of the rotating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a threaded rod, a moving block, a connecting rod, a telescopic rod, and a pressure plate.

[0015] 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.

[0016] like Figures 1 to 5 As shown, this utility model provides a bending device for vacuum equipment manufacturing, including a processing table 1. A fixed frame 2 is fixedly connected to the top of the processing table 1. A rectangular plate 3 is fixedly connected to the top of the fixed frame 2. A first motor 4 is fixedly connected to the front of the rectangular plate 3. A threaded rod 5 is fixedly sleeved at the other end of the output shaft of the first motor 4. The other end of the threaded rod 5 passes through the rectangular plate 3 and extends into the interior of the rectangular plate 3, and is threadedly sleeved with a moving block 6. The bottom of the moving block 6 is movably connected to the interior of the top of the fixed frame 2. A connecting rod 7 is hinged to the top of the moving block 6. A telescopic rod 8 is hinged to the other end of the connecting rod 7. The bottom end of the telescopic rod 8 passes through the fixed frame 2 and extends into the inner cavity of the fixed frame 2, and is fixedly connected with a pressure plate 9. When the first motor 4 starts running, the threaded rod 5 will rotate, thereby causing the moving block 6 to move horizontally backward under the limiting action of the fixed frame 2, thereby causing the connecting rod 7 to move. At this time, the telescopic rod 8 will drive the pressure plate 9 to move vertically downward along the interior of the fixed frame 2.

[0017] The bottom of the pressure plate 9 is fixedly connected to a soft pad 10, which is made of rubber. This design allows the pressure plate 9 to better press down on the board and prevent it from moving. At the same time, it prevents the pressure plate 9 from applying too much pressure and scratching the surface of the board.

[0018] The top of the fixed frame 2 is fixedly connected to a pneumatic cylinder 11. The other end of the pneumatic cylinder 11 passes through the fixed frame 2 and extends into the inner cavity of the fixed frame 2, and is fixedly connected to a bending head 12. A bending groove 14 is fixedly installed inside the processing table 1, and the bending groove 14 is located directly below the bending head 12. When the pneumatic cylinder 11 starts to run, it will cause the bending head 12 to move vertically downward. Finally, when the bending head 12 and the bending groove 14 cooperate, the bending operation of the plate will be realized.

[0019] Among them, the left and right sides of the top of the bending head 12 are fixedly connected to limit rods 13. The top of the limit rods 13 passes through the fixed frame 2 and extends to the outside of the fixed frame 2. Due to the limiting effect of the limit rods 13, the bending head 12 moves more smoothly in the subsequent movement and cooperates more precisely with the bending groove 14.

[0020] The second motor 15 is fixedly connected to the left side of the bottom of the processing table 1. The other end of the output shaft of the second motor 15 is fixedly sleeved with a rotating shaft 16. The other end of the rotating shaft 16 is fixedly sleeved with a rotating rod 17. The front and rear sides of the outer surface of the rotating rod 17 are movably connected with sleeve rods 18. When the second motor 15 starts to run, the rotating shaft 16 will drive the rotating rod 17 to rotate, thereby causing the rotating rod 17 to squeeze and push the two sleeve rods 18 to move.

[0021] The sleeve 18 is fixedly connected to a rectangular rod 19 on its outer side, and a sliding plate 20 is fixedly connected to the top of the rectangular rod 19. Movable plates 21 are fixedly connected to the left and right sides of the top of the sliding plate 20. The outer surface of the sliding plate 20 is movably connected to the interior of the processing table 1. When the sleeve 18 moves, it will drive the rectangular rod 19 and the sliding plate 20 to move horizontally back and forth under the limiting action of the processing table 1, and make the movable plates 21 move synchronously.

[0022] The processing table 1 has four support rods 22 fixedly connected to the four corners of its bottom. There are four support rods 22, and the four support rods 22 are all the same size. The design of the four support rods 22 evenly distributes the overall weight of the device and prevents the device from directly contacting the ground, thus preventing moisture damage.

[0023] Working principle and usage process of this utility model: First, place the board on top of the processing table 1 and start the second motor 15, causing the rotating shaft 16 to drive the rotating rod 17 to rotate. At this time, the rotating rod 17 will squeeze and push the sleeve rod 18, causing the two sleeve rods 18 to drive the two rectangular rods 19 and the sliding plate 20 to move horizontally towards each other under the limiting action of the processing table 1. Finally, the movable plate 21 moves towards the second motor 15, achieving the effect of centering and straightening the board, avoiding the board from being crooked and affecting the subsequent processing quality. Then, start the second motor 15 again to reset the movable plate 21.

[0024] Then, the first motor 4 is started, at which point the threaded rod 5 rotates, causing the moving block 6 to move horizontally backward under the limiting action of the fixed frame 2, thereby causing the connecting rod 7 to move. At this time, the telescopic rod 8 will drive the pressure plate 9 to move vertically downward along the inside of the fixed frame 2. Finally, when the soft pad 10 contacts the board, it will achieve the effect of fixing the board, making it less likely for the board to slip or shift during bending. At the same time, the soft pad 10 also prevents the pressure plate 9 from being too high and scratching the surface of the board. After the board is fixed, the pneumatic cylinder 11 is started, causing the bending head 12 to drive the limiting rod 13 to move vertically downward under the limiting action of the fixed frame 2. Finally, the bending head 12 cooperates with the bending groove 14 to realize the bending operation of the board.
