[0022] 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. Example 1

[0023] Please see Figures 1-2 This utility model discloses a combined mold for a bending machine used in continuous processing, including an upper mold 1 and an auxiliary bending assembly 5. The auxiliary bending assembly 5 includes a mounting frame 6 and a bidirectional lead screw 7. The bidirectional lead screw 7 is installed on the inner wall of the mounting frame 6. A bidirectional slider 8 is installed on the outer surface of the bidirectional lead screw 7. A motor 9 is installed at one end of the bidirectional lead screw 7. An electric slide table 10 is installed on the top surface of the bidirectional slider 8. A first slider 11 and a second slider 12 are installed on the outer surface of the electric slide table 10. An extension plate 14 is installed on the bottom surface of the first slider 11 and the second slider 12. A limiting hole 15 is opened on one side of the first slider 11 and the second slider 12. A second cylinder 13 is installed on the inner wall of the extension plate 14. A clamping plate 16 and a limiting plate 17 are installed on the top surface of the first slider 11 and the second slider 12.

[0024] The upper mold 1 and the lower combined mold 3 cooperate with each other. The lower part of the upper mold 1 is provided with a mounting base 2. The lower combined mold 3 and the first cylinder 4 are mounted on the top surface of the mounting base 2. The mounting frame 6 is mounted on the top surface of the first cylinder 4. The top surface of the first cylinder 4 is equipped with an auxiliary bending component 5. The top surface of the mounting base 2 and the bottom surface of the lower combined mold 3 are fixedly connected to each other. There are six first cylinders 4.

[0025] Three first cylinders 4 form a group, and two groups of first cylinders 4 are fixedly installed on both sides of the mounting base 2. The lower combination mold 3 is set in the middle of the two groups of first cylinders 4, and the top surface of the two groups of first cylinders 4 is fixedly connected to the bottom surface of a mounting frame 6.

[0026] Place the sheet metal to be bent on the worktable of the bending machine, ensuring that the sheet metal is aligned with the center line of the bending machine. Adjust the positions of the first slider 11 and the second slider 12 on the electric slide table 10. The first slider 11 is positioned in front of the second slider 12. The first slider 11 is mainly used to clamp the sheet metal, while the second slider 12 is used for auxiliary limiting to prevent the sheet metal from tilting during processing. Activate the first cylinder 4 to raise the mounting frame 6 and its auxiliary bending assembly 5, so that the first slider 11, the second slider 12, their clamping plate 16, and the limiting plate 17 are horizontally aligned with the processing area of ​​the lower combination mold 3. By moving the first slider 11 and the second slider 12, the sheet metal to be bent is clamped and its position is fixed. Example 2

[0027] Based on the above embodiment 1, please refer to Figures 3-5 The first cylinder 4 is used to change the height of the mounting frame 6 and the processing position of the lower combination mold 3. The inner wall of each mounting frame 6 is movably and rotatably connected to a two-way lead screw 7. One end of the two-way lead screw 7 is fixedly connected to the output end of a motor 9, and one side of the motor 9 is fixedly connected to one side of the mounting frame 6.

[0028] The outer surface of the bidirectional lead screw 7 is rotatably connected to the inner walls of the two bidirectional sliders 8. There are two electric slides 10, which are fixedly installed at equal intervals on the top surface of the bidirectional sliders 8. The bidirectional sliders 8 are driven to change the distance between the two electric slides 10 to adapt to plates of different widths.

[0029] Each electric slide table 10 has a first slider 11 and a second slider 12 slidably connected to its outer surface. The two first sliders 11 are used to clamp the sheet metal to be bent, and the second sliders 12 are used to assist in limiting the sheet metal to be bent. Two limiting holes 15 are opened on one side of each of the first sliders 11 and the second sliders 12.

[0030] An extension plate 14 is installed on one side of the bottom surface of the first slider 11 and the second slider 12. The clamping plate 16 connected to the first slider 11 through the extension plate 14 is used to clamp the plate. The clamping plate 16 connected to the second slider 12 through the extension plate 14 is used to limit the placement position of the plate to achieve the positioning effect.

[0031] Before the upper die 1 begins to move downwards, the second cylinder 13 is released if it is used for further auxiliary bending or positioning to avoid contact with the upper die. The upper die 1 is then activated to move downwards, cooperating with the lower combined die 3 to bend the sheet metal. During this process, the first cylinder 4 remains in an elevated state to ensure stable contact between the clamping plate 16 and the limiting plate 17 and the sheet metal, while not hindering the downward movement of the upper die. After bending is completed, the upper die 1 moves upwards back to its initial position. The first slider 11 and the second slider 12 continue to move, causing the clamping plate 16 and the limiting plate 17 to disengage from the sheet metal, releasing the sheet metal. The first cylinder 4 is then activated to return to its initial position, causing the mounting frame 6 and its auxiliary bending assembly 5 to return to their initial positions.

[0032] The working principle and usage process of this utility model are as follows: Place the sheet material to be bent on the worktable of the bending machine, ensuring that the position of the sheet material is aligned with the center line of the bending machine. Adjust the positions of the first slider 11 and the second slider 12 on the electric slide table 10. The first slider 11 is positioned in front of the second slider 12. The first slider 11 is mainly used to clamp the sheet material, while the second slider 12 is used for auxiliary limiting to prevent the sheet material from tilting during processing.

[0033] Lifting and clamping: Activating the first cylinder 4 lifts the mounting frame 6 and its auxiliary bending assembly 5, allowing the first slider 11 and the second slider 12, along with their clamping plate 16 and limiting plate 17, to be horizontally aligned with the processing area of ​​the lower assembly mold 3. The movement of the first slider 11 and the second slider 12 clamps the sheet metal to be bent and fixes its position.

[0034] Release the second cylinder: Before the upper mold 1 begins to move downward, release the second cylinder 13 if it is used for further assisting bending or positioning to avoid contact with the upper mold.

[0035] Bending operation: The upper die 1 is activated to move downwards, cooperating with the lower combined die 3 to bend the sheet metal. During this process, the first cylinder 4 remains in an elevated state to ensure stable contact between the clamping plate 16 and the limiting plate 17 and the sheet metal, while not hindering the downward movement of the upper die.

[0036] Release of clamps and return to position: After bending is completed, the upper die 1 moves upward to return to its initial position. The first slider 11 and the second slider 12 continue to move, causing the clamping plate 16 and the limiting plate 17 to disengage from the sheet metal, releasing the sheet metal. The first cylinder 4 is activated to return to its initial position, causing the mounting frame 6 and its auxiliary bending assembly 5 to return to their initial positions.

[0037] Reset and prepare for the next processing: The first slider 11 and the second slider 12 return to their preset positions, ready for the next processing. Remove the processed board material and place a new board material for the next cycle.
