[0002] "High-precision metal parts automated processing bending device" is a type of mechanical equipment used in the metal processing industry, specifically for bending metal sheets or metal plates.

[0003] Chinese utility model patent CN221966473U discloses a bending device for the production of mechanical parts. In use, the device uses a threaded lower pressure plate to easily replace pressure plates of different shapes. However, in actual use, the device, installed with screws, may generate significant mechanical vibration during the bending process, especially with thicker or harder metal materials. As the vibration accumulates, the threaded connection may loosen, affecting the stability of the pressure plate, causing inconsistent bending angles, and even workpiece displacement. Therefore, this invention proposes a high-precision bending device for automated processing of metal parts to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bending device for automated processing of high-precision metal parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending device for automated processing of high-precision metal parts includes a base plate, a side plate fixedly connected to the upper end of the base plate, the outer wall of the side plate being L-shaped, a sliding plate connected to the side plate via a telescopic mechanism, an upper folding plate installed on the outside of the sliding plate, a lower pressure plate connected to the base plate via multiple sets of screws, the upper folding plate and the lower pressure plate fitting together, multiple sets of positioning plates fixedly connected to the upper end of the base plate, the number of positioning plates being the same as the number of screws, each located on one side of the screws, a limiting groove being formed on the outer wall of the screw, and the inner wall being circular, a connecting rod being slidably connected to the outer wall of the positioning plate, a limiting plate being fixedly connected to the end of the connecting rod, the outer wall shape of the limiting plate fitting the inner wall of the limiting groove, and an elastic mechanism installed on the outer wall of the connecting rod to drive the limiting plate to fit tightly in the limiting groove.

[0010] Preferably, the radius of the limiting block is larger than the radius of the sliding rod, and the radius of the slider is larger than the radius of the connecting rod.

[0011] Preferably, each of the two sets of slide rods is fitted with a spring, one end of which is fixedly connected to the limiting block, and the other end of which is fixedly connected to the end face of the slide plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model effectively absorbs the vibration generated during bending by using the fitting design of the limiting plate and the limiting groove, as well as the elastic adjustment mechanism of the second spring. This avoids the problems of loose screws and unstable contact of the lower pressure plate. This not only ensures the precise contact between the workpiece and the bending device during bending, but also maintains the high precision of each bend, thus improving the quality and stability of the bending process.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A bending device for automated processing of high-precision metal parts includes a base plate 1, a side plate 2 fixedly connected to the upper end of the base plate 1, the outer wall of the side plate 2 being L-shaped, a sliding plate 4 connected to the side plate 2 via a telescopic mechanism, an upper bending plate 6 installed on the outside of the sliding plate 4, a lower pressure plate 5 connected to the base plate 1 via multiple sets of screws 10, the upper bending plate 6 and the lower pressure plate 5 fitting together, multiple sets of positioning plates 12 fixedly connected to the upper end of the base plate 1, the number of positioning plates 12 being the same as the number of screws 10, each located on one side of the multiple sets of screws 10, a limit groove 11 formed on the outer wall of the screw 10, and the inner wall being L-shaped. The circular positioning plate 12 has a connecting rod 14 slidably connected to its outer wall. A limiting plate 13 is fixedly connected to the end of the connecting rod 14. The outer wall of the limiting plate 13 fits the inner wall of the limiting groove 11. An elastic mechanism is installed on the outer wall of the connecting rod 14 to drive the limiting plate 13 to fit tightly in the limiting groove 11. The fitting design of the limiting plate 13 and the limiting groove 11 can effectively limit the loosening of the screw 10 due to vibration during use, thereby ensuring the clamping force and contact stability between the lower pressure plates 5. This avoids the screw 10 from loosening due to vibration, thus maintaining bending accuracy and quality.

[0021] The elastic mechanism includes a second spring 16 sleeved on the outer wall of the connecting rod 14. A slider 15 is fixedly connected to the end of the connecting rod 14. The two ends of the second spring 16 are fixedly connected to the positioning plate 12 and the outer wall of the slider 15, respectively. The second spring 16 can convert vibration energy into elastic deformation through its elastic properties, thereby reducing the vibration on other parts of the device and ensuring the stability of the limiting plate 13 inserted into the limiting groove 11.

[0022] The telescopic mechanism includes a hydraulic cylinder 3 fixedly connected to the end face of the side plate 2. The telescopic end of the hydraulic cylinder 3 is fixedly connected to the slide plate 4. Two sets of sliding rods 8 are slidably connected to the outer wall of the slide plate 4, and their positions are symmetrical. Limit blocks 7 are fixedly connected to the ends of both sets of sliding rods 8. The radius of the limit block 7 is larger than the radius of the sliding rod 8, and the radius of the slider 15 is larger than the radius of the connecting rod 14. Springs 9 are sleeved on the outer walls of both sets of sliding rods 8. One end of the spring 9 is fixedly connected to the limit block 7, and the other end of the spring 9 is fixedly connected to the end face of the slide plate 4. Through its elastic properties, the spring 9 can effectively alleviate the instantaneous impact force that may be generated in the hydraulic system during the telescopic process, thereby reducing mechanical wear and extending the service life of the device.

[0023] In this utility model, when the device is used, the hydraulic cylinder 3 provides driving force to drive the slide plate 4 to move up and down along the track on the side plate 2, so that the upper bending plate 6 moves closer to the lower pressure plate 5, thereby realizing the bending of the metal workpiece.

[0024] The screw 10, through the engagement of the limiting groove 11 on the outer wall and the positioning plate 12, ensures that vibration will not cause the screw 10 to loosen during bending. The limiting groove 11 and the limiting plate 13 form a stable locking mechanism through precise engagement. The kinetic energy generated by vibration is absorbed by the limiting plate 13, avoiding the problems of screw 10 loosening and unstable contact of the lower pressure plate 5, thereby maintaining bending accuracy. Based on the engagement of the limiting plate 13 and the limiting groove 11, the spring 16 provides sufficient elasticity to the limiting plate 13, enabling the limiting plate 13 to adaptively adjust when the screw 10 is affected by vibration, effectively absorbing vibration and avoiding loosening or error in the connection of the screw 10, thereby improving the accuracy and stability during bending.

[0025] The spring 9, which is sleeved on the outside of the slide bar 8, is used to buffer the rapid movement of the slide plate 4 or the instantaneous impact caused by the hydraulic system, further improving the stability of the equipment during operation. The function of the spring 9 is to absorb the reaction force in the sliding and reduce the impact of vibration, thereby maintaining the precise contact between the slide plate 4, the limit block 7 and the upper folding plate 6, and ensuring consistency in each bend.

[0026] During the bending process, metal materials may experience uneven stress or material rebound due to factors such as different hardness and thickness. To address this, the design of spring 19, spring 216, and limit plate 13 provides effective adaptive force adjustment, ensuring that the equipment can automatically adjust the pressure and force transmission according to actual needs under different workpieces and bending conditions, thus minimizing accuracy problems caused by uneven force or processing errors.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
