[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figures 1-5 This utility model provides a high-precision CNC bending machine, including a bending machine body 1. A base plate 75 is fixedly connected to each side of the bending machine body 1. A fixing block 71 is fixedly connected to the corner of the base plate 75. A slide rail 7 is fixedly connected between every two fixing blocks 71. An electric slider 72 is slidably connected to the surface of each slide rail 7. A first connecting block 73 is fixedly connected between two opposing electric sliders 72. A guide cylinder 74 is slidably connected between two first connecting blocks 73. A second connecting block 10 is fixedly connected to the upper end of the guide cylinder 74. During operation, the pad 6 provides stable support for the bending machine body 1, preventing displacement due to vibration during operation. The electric slider 72 can slide along the slide rail 7, moving the first connecting block 73. Simultaneously, the guide cylinder 74 can slide between the two first connecting blocks 73, thereby adjusting the position of the second connecting block 10. This allows the second connecting block 10 to be adjusted to a suitable working position according to the size of the workpiece and bending requirements, facilitating subsequent workpiece clamping operations and improving the applicability of the equipment.

[0023] Furthermore, such as Figure 2 and Figure 4As shown, a first motor 101 is fixedly connected to the other end of the inner side of the second connecting block 10. A first gear 104 is driven to the inner side of the first motor 101. A first gear plate 102 is meshed with the side of the first gear 104 closest to the bending machine body 1, and a second gear plate 103 is meshed with the other side of the first gear 104. A lower clamping block 106 is fixedly connected to the inner side of the first gear plate 102, and an upper clamping block 105 is fixedly connected to the inner side of the second gear plate 103. During operation, when it is necessary to clamp and fix the workpiece, the first motor 101 is started. The first motor 101 drives the first gear 104 to rotate. Since the first gear 104 meshes with the first gear plate 102 and the second gear plate 103 respectively, the rotation of the first gear 104 will drive the first gear plate 102 and the second gear plate 103 to move relative to each other, thereby driving the lower clamping block 106 and the upper clamping block 105 to move closer to each other, firmly clamping the workpiece between them. This gear and toothed plate transmission method has high transmission accuracy, which can ensure the accurate clamping position of the lower clamping block 106 and the upper clamping block 105, avoid the workpiece from shifting during the bending process, and effectively improve the bending accuracy. At the same time, the clamping force can be adjusted by controlling the output power of the first motor 101, which is suitable for workpieces of different thicknesses and materials.

[0024] Furthermore, such as Figure 1 As shown, circular grooves 56 are provided at both ends of the surface of the bending machine body 1. A circular slider 55 is slidably connected inside the circular grooves 56. A connecting rod 54 is fixedly connected to the surface of the circular slider 55. A second motor 52 is fixedly connected to the surface of the bending machine body 1 near the circular grooves 56. A second gear 53 is driven to the surface of the second motor 52. A third toothed plate 51 that meshes with the second gear 53 is slidably connected to the surface of the bending machine body 1 on one side of the second gear 53. A lifting column 5 is fixedly connected to the surface of the third toothed plate 51. A lifting plate 11 is fixedly connected to the other end of the lifting column 5. A first locking block 8 is fixedly connected to the lower end of the lifting plate 11. A pressure plate 2 is locked to the lower end of the first locking block 8. A second locking block 9 is fixedly connected to the surface of the bending machine body 1 at the lower end of the pressure plate 2. A bottom plate 3 is locked to the upper end of the second locking block 9. A pad 6 is fixedly connected to the bottom corner of the bending machine body 1. During operation, the appropriate pressure plate 2 and base plate 3 are replaced using the first clamping block 8 and the second clamping block 9, respectively, according to the bending shape and size requirements of the workpiece. This convenient replacement improves the equipment's adaptability to different bending needs. The second motor 52 is activated, driving the second gear 53 to rotate. The second gear 53 drives the third toothed plate 51, which in turn drives the lifting column 5 to move up and down. The lifting column 5 then drives the lifting plate 11 and pressure plate 2 to move up and down, performing a bending operation on the clamped workpiece with the assistance of the base plate 3. The circular slider 55 and circular groove 56 guide and stabilize the third toothed plate 51 during its sliding process, preventing deviation and ensuring the accuracy of the lifting column 5's movement of the pressure plate 2, further improving the bending accuracy of the workpiece.

[0025] Working principle: First, the workpiece to be processed is placed on the base plate 3. The electric slider 72 slides along the slide rail 7, driving the first connecting block 73 to move. At the same time, the guide cylinder 74 slides between the two first connecting blocks 73, adjusting the second connecting block 10 to a suitable clamping position. The first motor 101 is started, driving the first gear 104 to rotate. The first gear 104 drives the first toothed plate 102 and the second toothed plate 103 to move relative to each other, causing the lower clamping block 106 and the upper clamping block 105 to move closer together, clamping and fixing the workpiece. According to the bending requirements of the workpiece, the first connecting block 106 is used to adjust the workpiece to a suitable clamping position. The first clamping block 8 and the second clamping block 9 are respectively fitted with suitable pressure plates 2 and base plates 3. The second motor 52 is started, which drives the second gear 53 to rotate. The second gear 53 drives the third toothed plate 51 to slide. The third toothed plate 51 drives the lifting column 5, the lifting plate 11, and the pressure plate 2 to move downward. With the cooperation of the base plate 3, the workpiece is bent. The circular slider 55 slides in the circular groove 56, providing guidance and stability for the sliding of the third toothed plate 51. The pad 6 at the bottom of the bending machine body 1 provides stable support for the entire equipment and prevents displacement during operation. After bending is completed, the second motor 52 is turned off, the pressure plate 2 is reset, the first motor 101 is turned off, the lower clamping block 106 and the upper clamping block 105 are released, and the bent workpiece is taken out, completing one bending operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
