Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, specifically a metal plate bending machine. Background Technology

[0002] Metal sheet bending machines use hydraulic systems, servo motors, or mechanical levers to drive a slider in precise movement. This, combined with upper and lower dies, applies precise pressure to the metal sheet, causing plastic deformation within the die gap to form the desired angle or precise shape. However, current technology still has limitations. Due to cost considerations, not all bending machines are fully automatic; a significant portion remain semi-automatic. In this mode, operators must manually align the bending position of the metal sheet with the bending machine's cutter head. This process is not only inefficient but also highly susceptible to human error, leading to alignment deviations and affecting bending accuracy. Therefore, it is necessary to improve the technology of metal sheet bending machines to enhance their automation and operational accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide a metal plate bending machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal plate bending machine, comprising a fixed frame, a bending groove fixedly provided at the lower end of the fixed frame, a bending mechanism provided at the upper end of the fixed frame, the bending mechanism comprising a hydraulic cylinder, a movable plate, and a bending head, the hydraulic cylinder fixedly provided at the upper end of the fixed frame, the movable plate fixedly provided at the lower end of the hydraulic cylinder, the bending head fixedly provided at the lower end of the movable plate, a positioning mechanism for positioning the bent plate material provided on one side of the surface of the fixed frame, the positioning mechanism comprising a telescopic rod, a translation frame, a mounting plate, and a limiting plate, telescopic rods fixedly provided on both sides of the bottom of the fixed frame, a translation frame fixedly provided at the movable end of the telescopic rod, a mounting plate provided at the upper end of the translation frame, and a limiting plate fixedly provided at the upper end of the mounting plate.

[0005] Preferably, a threaded sleeve is movably mounted on the inner middle of the fixed frame via a bearing, and a screw is fixedly mounted on the middle of the translation frame. The threaded sleeve is movably mounted on the outer surface of the screw via a thread. By rotating the threaded sleeve, the screw and the translation frame and the limiting plate can be moved left and right under the driving action of the thread, thereby changing the distance between the limiting plate and the bending head.

[0006] Preferably, the upper outer surface of the translation frame has a mounting groove, and the lower end of the mounting plate is fixedly provided with a mounting block. This device adopts a modular design, and the mounting plate and the limiting plate are precisely inserted into the mounting groove by the mounting block to achieve a stable connection. This design provides flexibility for quick replacement of the mounting plate and the limiting plate. Given that not all working conditions require horizontal bending in actual bending operations, some scenarios require bending at specific tilt angles (such as the bending line forming an angle of 30°, 45°, etc. with the sheet metal surface), by pre-preparing limiting plate components corresponding to commonly used tilt angles, the equipment can be quickly switched according to needs during production, significantly improving its adaptability to diverse bending processes.

[0007] Preferably, a locking screw is provided between the mounting block and the mounting groove. The mounting block and the mounting groove of this device are fixed by the locking screw, and different mounting plates can be disassembled and replaced at any time when needed.

[0008] Preferably, sliding rods are movably provided on both sides of the lower end of the fixed frame, and the movable plate is movably sleeved on the outer surface of the sliding rods. The sliding rods can ensure the stability of the movable plate and the bending head moving up and down.

[0009] Preferably, the limiting plate has a trapezoidal cross-section. Considering the upward bending characteristic of the sheet material under pressure during bending, and to avoid motion interference between the limiting plate and the bent sheet material, this device innovatively adopts a trapezoidal cross-section limiting plate design. This structure creates a dynamic avoidance space through its trapezoidal profile, which is narrower at the top and wider at the bottom: when the sheet material bends, its bending trajectory makes progressive contact with the hypotenuse of the trapezoidal limiting plate, ensuring rigid constraint during the initial positioning stage while automatically eliminating the risk of interference during the bending process through the guiding effect of the hypotenuse.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model pre-adjusts the distance between the limiting plate and the bending head. Each time the plate is bent, it only needs to be pushed and brought into close contact with the limiting plate. This allows workers to quickly align and bend plates of the same model and with the same requirements, thereby improving the processing efficiency and quality of the device.

[0012] 2. This utility model adopts a modular design. The mounting plate and the limiting plate are precisely inserted into the mounting groove by the mounting block to achieve a stable connection. This design provides flexibility for quick replacement of the mounting plate and the limiting plate. Given that not all working conditions require horizontal bending in actual bending operations, some scenarios require bending at specific tilt angles (such as the bending line forming an angle of 30° or 45° with the sheet surface), by pre-preparing limiting plate components corresponding to commonly used tilt angles, the equipment can be quickly switched according to needs during production, significantly improving its adaptability to diverse bending processes.

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a metal plate bending machine, including a fixed frame 1, a bending groove 2 fixedly provided at the lower end of the fixed frame 1, a bending mechanism provided at the upper end of the fixed frame 1, the bending mechanism including a hydraulic cylinder 3, a movable plate 4, and a bending head 5. The hydraulic cylinder 3 is fixedly provided at the upper end of the fixed frame 1, the movable plate 4 is fixedly provided at the lower end of the hydraulic cylinder 3, and the bending head 5 is fixedly provided at the lower end of the movable plate 4. A positioning mechanism for positioning the bent plate is provided on one side of the surface of the fixed frame 1. The positioning mechanism includes a telescopic rod 6, a translation frame 7, a mounting plate 8, and a limiting plate 9. The telescopic rod 6 is fixedly provided on both sides of the bottom of the fixed frame 1. The translation frame 7 is fixedly provided at the movable end of the telescopic rod 6. The mounting plate 8 is provided at the upper end of the translation frame 7, and the limiting plate 9 is fixedly provided at the upper end of the mounting plate 8.

[0021] The fixed frame 1 has a threaded sleeve 10 movably mounted on the inner side of the middle via a bearing. The translation frame 7 has a screw 11 fixedly mounted in the middle. The threaded sleeve 10 is movably mounted on the outer surface of the screw 11 via a thread. By rotating the threaded sleeve 10, the screw 11 and the translation frame 7 and the limiting plate 9 can be moved left and right under the driving action of the thread, thereby changing the distance between the limiting plate 9 and the bending head 5.

[0022] The upper outer surface of the translation frame 7 is provided with a mounting groove 12, and the lower end of the mounting plate 8 is fixedly provided with a mounting block 13. This device adopts a modular design. The mounting plate 8 and the limiting plate 9 are precisely inserted into the mounting groove 12 through the mounting block 13 to achieve a stable connection. This design provides the flexibility to quickly replace the mounting plate 8 and the limiting plate 9. In actual bending operations, not all working conditions require horizontal bending. Some scenarios require bending at specific tilt angles (such as the bending line forming an angle of 30°, 45°, etc. with the surface of the sheet). By pre-preparing limiting plate 9 components corresponding to commonly used tilt angles, the equipment can be quickly switched according to needs during production, significantly improving its adaptability to diverse bending processes.

[0023] A locking screw is provided between the mounting block 13 and the mounting groove 12. The mounting block 13 and the mounting groove 12 of this device are fixed by the locking screw, and different mounting plates 8 can be disassembled and replaced at any time when needed.

[0024] The fixed frame 1 has sliding rods 14 movably installed on both sides of the lower end. The movable plate 4 is movably sleeved on the outer surface of the sliding rod 14. The sliding rod 14 can ensure the stability of the movable plate 4 and the bending head 5 moving up and down.

[0025] The limiting plate 9 has a trapezoidal cross-section. To address the upward bending of the sheet material under pressure during bending, and to prevent motion interference between the limiting plate 9 and the bent sheet material, this device innovatively adopts a trapezoidal cross-section limiting plate 9 design. This structure creates a dynamic avoidance space through its trapezoidal profile, which is narrower at the top and wider at the bottom: when the sheet material bends, its bending trajectory makes progressive contact with the hypotenuse of the trapezoidal limiting plate 9, ensuring rigid constraint during the initial positioning stage while automatically eliminating interference risks through the guiding effect of the hypotenuse during bending.

[0026] When using this device, the bending head 5 is pushed downward by the extension and retraction of the hydraulic cylinder 3, which works in conjunction with the bending groove 2 to perform the bending operation of the sheet metal.

[0027] When bending, the distance between the limiting plate 9 and the bending head 5 is pre-adjusted. Then, each time the plate is bent, it is only necessary to push the plate and the limiting plate 9 to make close contact with each other. In this way, when the worker is bending, the plates of the same model and the same requirements can be quickly aligned and bent, thereby improving the processing efficiency and processing quality of the device.

[0028] Meanwhile, this device employs a modular design. The mounting plate 8 and the limiting plate 9 are precisely engaged into the mounting groove 12 via the mounting block 13, achieving a secure connection. This design provides flexibility for quick replacement of the mounting plate 8 and the limiting plate 9. Given that in actual bending operations, not all conditions require horizontal bending; some scenarios require bending at specific angles (such as the bending line forming an angle of 30° or 45° with the sheet metal surface), such as… Figure 4 As shown, by pre-preparing the limit plate 9 components corresponding to commonly used tilt angles, the equipment can be quickly switched according to the needs during the production process, significantly improving its adaptability to diverse bending processes.
