For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0020] Reference Figures 1 to 4 In the embodiment of the utility model, a CNC sheet metal bending device includes: a base 1, a hydraulic rod 2 is fixedly arranged above the base 1, a lower connecting seat 3 is fixedly arranged above the hydraulic rod 2, a connecting piece 4 is rotatably connected above the lower connecting seat 3, an upper connecting seat 5 is rotatably connected above the connecting piece 4, a supporting plate 6 is fixedly arranged above the upper connecting seat 5, a slide groove 7 is opened above the supporting plate 6, a movable block 8 is fixedly arranged on the side of the supporting plate 6, and a movable shaft 9 is clamped in the middle of the movable block 8.

[0021] The above scheme is adopted: the base 1 serves as the foundation of the entire device, firmly supporting the various components above. The hydraulic rod 2 is fixed on the top of the base 1, which can provide a stable and adjustable driving force. Through the rotation connection of the lower connecting seat 3, the connecting member 4 and the upper connecting seat 5, the lifting movement of the hydraulic rod 2 is efficiently converted into the folding movement of the support plate 6. This structure is compact and has high power transmission efficiency.

[0022] A card plate adjustment base 10 is slidably arranged above the slide groove 7, a movable groove 11 is opened on the inner side of the card plate adjustment base 10, a card plate movable seat 12 is slidably arranged above the movable groove 11, a push handle 13 is fixedly arranged on one side of the card plate movable seat 12, a card plate 14 is rotatably connected to the other side of the card plate movable seat 12, and a rubber pressure plate 15 is fixedly arranged on the side of the card plate 14.

[0023] The above scheme is adopted: the card plate adjustment base 10 slides on the support plate 6 through the slide groove 7, and can be flexibly adjusted according to the length and width of the sheet metal, so as to adapt to the sheet metal processing requirements of different specifications. This design increases the versatility and flexibility of the device. The design of the push handle 13 allows the operator to easily adjust the position of the card plate movable seat 12 and the card plate 14, thereby realizing the rapid clamping and fixation of the sheet metal.

[0024] A top plate support rod 16 is fixedly provided on the side of the base 1, a top plate 17 is fixedly connected to one side above the top plate support rod 16, a telescopic rod 18 is fixedly connected below the top plate 17, a pressure head connecting seat 19 is fixedly provided below the telescopic rod 18, and a pressure head 20 is fixedly provided below the pressure head connecting seat 19.

[0025] The above solution is adopted: the top plate 17 is firmly mounted on the side of the base 1 through the top plate support rod 16, providing stable support and positioning for the telescopic rod 18 and the pressing head 20 below. This design ensures that the pressing head 20 can maintain a stable position and force during the bending process, thereby improving the accuracy and consistency of the bending.

[0026] The connecting member 4 is located between the lower connecting seat 3 and the upper connecting seat 5. When the hydraulic rod 2 is pushed upward, the connecting member 4 will also rotate a certain angle, so that the support plate 6 can be folded at a certain angle through the movable shaft 9, thereby folding the sheet metal. There are two groups of support plates 6, and the support plates 6 are folded against each other. There are multiple groups of hydraulic rods 2.

[0027] The above solution is adopted: the connecting member 4 is located between the lower connecting seat 3 and the upper connecting seat 5, and its rotating connection design allows the support plate 6 to be folded at a certain angle under the push of the hydraulic rod 2. This design enables the device to adapt to bending requirements at different angles, thereby increasing the flexibility and adaptability of the device.

[0028] The card plate adjustment base 10 moves through the slide groove 7 to adapt to sheet metals of different lengths. The card plate movable seat 12 slides above the card plate adjustment base 10 through the movable groove 11 to adapt to sheet metals of different widths. The push handle 13 facilitates pushing the card plate movable seat 12, and the card plate 14 can be rotated at a certain angle to fix the edge of the sheet metal.

[0029] The above scheme is adopted: the movable seat 12 of the card plate slides on the movable groove 11, and cooperates with the operation of the push handle 13 to accurately control the position of the card plate 14. The card plate 14 contacts the sheet metal through the rubber pressure plate 15. The softness and elasticity of the rubber can be used to achieve stable and uniform clamping of the sheet metal. This clamping method not only ensures the stability of the sheet metal during the bending process, but also reduces damage and scratches on the surface of the sheet metal.

[0030] A control device is provided inside the top plate 17, which can drive the telescopic rod 18 to push the pressure head 20. The pressure head 20 is located above the support plate 6. The pressure head 20 can press and fix the middle part of the sheet metal, making it convenient for the support plate 6 to bend the sheet metal.

[0031] The above solution is adopted: the introduction of the telescopic rod 18 makes it possible to flexibly adjust the height and pressing force of the pressing head 20. By adjusting the length of the telescopic rod 18, it can adapt to sheet metal parts of different thicknesses and materials, ensuring that the sheet metal parts can be stably pressed and fixed during the bending process. This adjustability increases the adaptability and flexibility of the device.

[0032] The working principle of the utility model is as follows: first, the device is in a stationary state, the hydraulic rod 2 is in the lowest position, the support plate 6 is in a horizontal state, the card plate adjustment base 10 and the card plate movable seat 12 are both in the initial position of their sliding range to adapt to sheet metals of different sizes, the telescopic rod 18 and the pressure head 20 under the top plate 17 are also in the initial position and do not contact the sheet metal below. The operator places the sheet metal to be bent on the support plate 6, and adjusts the position of the card plate 14 and the rubber pressure plate 15 through the movement of the slide groove 7 and the card plate adjustment base 10, and the sliding of the movable groove 11 and the card plate movable seat 12 to adapt and fix the edge of the sheet metal, and the middle part of the sheet metal can be pressed by the control device in the top plate 17 to drive the telescopic rod 18 and the pressure head 20 Tightly fixed, when the hydraulic rod 2 starts to push upward, the support plate 6 is folded at a certain angle around the movable axis 9 through the rotation of the connecting piece 4. Since the support plates 6 are provided in two groups and are folded against each other, the sheet metal is also bent accordingly under the folding action of the support plates 6. During the bending process, the pressure head 20 under the top plate 17 always presses the middle part of the sheet metal to ensure the accuracy and stability of the bending. When the sheet metal is bent to a predetermined angle, the hydraulic rod 2 stops moving, and the operator can raise the pressure head 20 through the control device and take out the bent sheet metal from the support plate 6. Then, the operator can readjust the position of the card plate adjustment base 10, the card plate movable seat 12 and the pressure head 20 to perform the next bending operation.

[0033] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
