On both sides of the top of the base 1 of the numerically controlled bending machine, a top frame 8 of the numerically controlled bending machine is fixedly connected. Inside the top frame 8 of the numerically controlled bending machine, a bending plate 10 is provided. At the top end inside the top frame 8 of the numerically controlled bending machine, a hydraulic cylinder 9 is installed. At the bottom end of the bending plate 10, a mounting plate 7 is fixedly connected. At the front end of the mounting plate 7, a fixing bolt 13 is provided. At the bottom end of the mounting plate 7, a bending die 6 is installed. At the top end of the fixed slide bar 2, a support plate 4 is provided. On one side of the top of the support plate 4, a limiting plate 14 is provided. An adjusting component is arranged outside the fixed slide bar 2;

[0026] The adjusting component includes an adjusting sliding sleeve 15. The adjusting sliding sleeve 15 is sleeved outside the fixed slide bar 2. On both sides of the bottom end of the adjusting sliding sleeve 15, a support rod 3 is fixedly connected. At the top end of the fixed slide bar 2, a positioning slot 19 is provided. At the top end of the adjusting sliding sleeve 15, a positioning plug 16 is provided. Between the positioning plug 16 and the adjusting sliding sleeve 15, a spring 17 is fixedly connected. Inside the adjusting sliding sleeve 15, a ball 18 is movably connected;

[0027] The bottom end of the positioning plug 16 penetrates through the adjusting sliding sleeve 15 and is embedded inside the positioning slot 19. The adjusting sliding sleeve 15 is sleeved outside the fixed slide bar 2. The bottom end of the ball 18 is in contact with the outer wall of the fixed slide bar 2;

[0028] Specifically, as Figure 1 and Figure 2 shown, the distance between the support plates 4 can be adjusted according to the length requirement of the plate. When adjusting, only need to pull up the positioning plug 16 upwards. When the bottom of the positioning plug 16 moves out from inside the positioning slot 19, the adjusting sliding sleeve 15 can be pushed to slide on the fixed slide bar 2. After the adjusting sliding sleeve 15 drives the support plate 4 to move to a suitable position, then release the positioning plug 16. The spring 17 at the bottom of the positioning plug 16 can make it re-insert into the corresponding positioning slot 19 to achieve fixation.

[0029] Embodiment 2: On both sides of the bottom end of the support plate 4, a bolt mounting sleeve 26 is fixedly connected. On one side of the top of the support plate 4, an elastic telescopic rod 25 is fixedly connected. At the bottom end of the limiting plate 14, a rubber pad 24 is fixedly connected. A bolt hole is provided inside the support rod 3. The top end of the support rod 3 is embedded inside the bolt mounting sleeve 26 for bolt fixation;

[0030] Specifically, as Figure 1 and Figure 4 shown, the limiting plate 14 at the top of the support plate 4 can limit the power distribution cabinet plate during the bending process. The limiting plate 14 is installed above the plate. When the bending machine presses down the plate for bending, the limiting plate 14 and the elastic telescopic rod 25 have the function of elastic limiting, avoiding excessive warping of the plate and not affecting the normal bending process.

[0031] Embodiment 3: Limit sliders 11 are fixedly connected to both sides of the bending plate 10. Limit slideways 12 are fixedly connected to both sides inside the top frame 8 of the numerical control bending machine. The limit sliders 11 are sleeved outside the limit slideways 12 and are slidably connected. Mounting rods 21 are fixedly connected to both sides of the bending groove 5. Positioning blocks 20 are fixedly connected to both sides at the bottom end of the bending groove 5. An installation bolt 22 is arranged at the front end of the positioning block 20. An installation groove 23 is arranged at the top end of the base 1 of the numerical control bending machine. The bottom end of the mounting rod 21 is embedded inside the installation groove 23. One end of the installation bolt 22 is embedded inside the mounting rod 21;

[0032] Specifically, as Figure 1 and Figure 3 shown, when the bending angle and groove requirements are different, the bending groove 5 and the bending die 6 can be replaced. When replacing the bending die 6, only need to unscrew the fixing bolt 13 and then the old one can be disassembled and the new one can be installed. When replacing the bending groove 5, unscrew the installation bolt 22 and move the mounting rod 21 at the bottom of the bending groove 5 out of the installation groove 23 to complete the replacement.

[0033] Working principle: When the utility model is in use, first adjust the distance between the support plates 4 according to the plate material. During adjustment, only need to pull up the positioning plug rod 16, and when the bottom of the positioning plug rod 16 moves out of the positioning slot 19, it can push the adjusting sliding sleeve 15 to slide on the fixed sliding rod 2. After the adjusting sliding sleeve 15 drives the support plate 4 to move to a suitable position, release the positioning plug rod 16. The spring 17 at the bottom of the positioning plug rod 16 can make it re-insert into the corresponding positioning slot 19 to achieve fixation. Then place the plate material on the support plate 4. The limiting plate 14 on the support plate 4 can limit the plate material. The limiting plate 14 is installed above the plate material. When the bending machine presses down on the plate material for bending, the limiting plate 14 and the elastic telescopic rod 25 have the function of elastic limit, which can prevent the plate material from warping excessively and does not affect the normal bending process. Subsequently, the hydraulic cylinder 9 pushes the bending plate 10 downward. The bending die 6 at the bottom of the bending plate 10 presses on the plate material and cooperates with the bending groove 5 to achieve the bending process. When the bending angle and groove requirements are different, the bending groove 5 and the bending die 6 can be replaced. When replacing the bending die 6, only need to unscrew the fixing bolt 13 and then the old one can be disassembled and the new one can be installed. When replacing the bending groove 5, unscrew the installation bolt 22 and move the mounting rod 21 at the bottom of the bending groove 5 out of the installation groove 23 to complete the replacement. This structure realizes the function of being convenient for flexible disassembly and replacement, and improves the flexibility of use.
