The slider and the slide rail are generally fixed to the device by bolts. During the installation or disassembly process, the bolts need to be screwed one by one, the operation is relatively cumbersome, the installation or disassembly process is relatively slow, and the labor intensity of the staff is increased.

Specific implementation manner

[0019] The technical solution of the utility model will be described below in conjunction with the drawings and embodiments.

[0020] Such as Figures 1-4As shown in the figure, a guiding device for a numerical control bending machine according to the present utility model includes a base 1. It is characterized in that a bending seat 2 is fixedly installed on the top of the base 1, a support frame 3 is fixedly installed on the top of the base 1, a hydraulic push rod 4 is fixedly installed on the top of the support frame 3, a fixed box 5 is fixedly installed at the output end of the hydraulic push rod 4, a bending head 6 is fixedly installed at the bottom of the fixed box 5, a driving component is arranged inside the fixed box 5, and a limiting plate 15 is arranged inside the fixed box 5 through the driving component. The driving component includes a first motor 7 arranged at the rear side of the fixed box 5. The output end of the first motor 7 penetrates through the fixed box 5 and extends into the fixed box 5 and is fixedly installed with a rotating shaft 8. A first bevel gear 9 is fixedly installed on the surface of the rotating shaft 8. A second bevel gear 10 is meshed on the surface of the first bevel gear 9. A first screw rod 11 is fixedly installed inside the second bevel gear 10. A fixing plate 12 is rotatably connected to the surface of the first screw rod 11. The fixing plate 12 is fixedly connected to the fixed box 5. A moving block 13 is threadedly connected to the surface of the first screw rod 11. The moving block 13 is fixedly connected to the limiting plate 15. A guiding rod 14 is slidably connected inside the moving block 13. The guiding rod 14 is fixedly connected to the fixing plate 12, which is convenient for providing a driving force for the mutual movement of the limiting plate 15, facilitating the movement of the limiting plate 15 more conveniently, and thus facilitating the subsequent more convenient limiting of the slider 18 by the limiting plate 15. The limiting plate 15 is slidably connected to the fixed box 5. Installation blocks 16 are fixedly installed on both the left and right sides of the fixed box 5. A slot 17 is opened at the bottom of the installation block 16. A slider 18 is inserted into the slot 17. A slide rail 19 is slidably connected to the surface of the slider 18. The slide rail 19 is lapped with the support frame 3. A positioning groove 20 is opened on the opposite surface of the slide rail 19. A moving component is arranged at the rear side of the support frame 3. A positioning block 25 is arranged inside the support frame 3 through the moving component. The moving component includes a fixed frame 21 arranged at the rear side of the support frame 3. A second motor 22 is fixedly installed on the right side of the fixed frame 21. The output end of the second motor 22 penetrates through the fixed frame 21 and extends into the fixed frame 21 and is fixedly installed with a second screw rod 23. The second screw rod 23 is a bidirectional threaded rod and is made of a metal material. A moving plate 24 is threadedly connected to the surface of the second screw rod 23. The moving plate 24 is slidably connected to the fixed frame 21. The moving plate 24 is fixedly connected to the positioning block 25, which is convenient for automatically adjusting the position of the positioning block 25. When the positioning block 25 is completely inserted into the positioning groove 20, it is convenient to fix the slide rail 19. When the positioning block 25 is separated from the positioning groove 20, it is convenient to cancel the fixation of the slide rail 19. When replacing the slider 18 and the slide rail 19, the driving component is used to make the limiting plates 15 approach each other, so that the limiting plates 15 leave from below the slider 18. Then the slider 18 is moved downward to be separated from the slot 17. Then the moving component is used to make the positioning blocks 25 approach each other and be separated from the positioning groove 20. Then the slide rail 19 and the slider 18 are disassembled. The new slide rail 19 is placed at a suitable position on the inner wall of the support frame 3. The moving component is used to make the positioning blocks 25 move away from each other, so that the positioning blocks 25 are completely inserted into the positioning groove 20 to complete the fixation of the slide rail 19.The limiting plates 15 are moved away from each other by the driving component, causing the limiting plates 15 to move below the slider 18 to limit the slider 18, making the installation and disassembly of the slider 18 and the slide rail 19 relatively simple, improving the replacement speed of the slider 18 and the slide rail 19, avoiding fixing the slider 18 and the slide rail 19 by using bolts, and reducing the labor intensity of the staff.

[0021] Specifically, the number of the positioning grooves 20 is multiple, and the positioning blocks 25 are adapted to the positioning grooves 20, enabling the positioning blocks 25 to be better inserted into the positioning grooves 20 and preventing the positioning blocks 25 from shaking in the positioning grooves 20, so that the slide rail 19 can be fixed more stably.

[0022] Specifically, the slider 18 has an I-shaped structure and is made of metal. The I-shaped structure of the slider 18 can prevent the slider 18 from falling off the mounting block 16 and the slide rail 19, thus facilitating more stable guiding of the movement of the fixed box 5 and the elbow 6 subsequently. Moreover, since the slider 18 is made of metal, the slider 18 has higher structural strength and is thus more durable.

[0023] Specifically, the number of the sliders 18 is multiple, and the multiple sliders 18 are symmetrically distributed. By arranging the multiple symmetric sliders 18, the movement of the fixed box 5 and the elbow 6 can be guided more stably, avoiding the deviation of the movement of the fixed box 5 and the elbow 6.

[0024] Working principle of the utility model: Place the metal plate on the bending seat 2, start the hydraulic push rod 4, so that the fixed box 5 and the bending head 6 move downward along the slide rail 19 through the slider 18 to bend the metal plate. When the slider 18 and the slide rail 19 are worn and need to be replaced, start the first motor 7 to make the rotating shaft 8 rotate, make the first bevel gear 9 rotate, make the second bevel gear 10 rotate, make the first screw rod 11 rotate, make the moving blocks 13 approach each other along the guide rods 14, make the limiting plates 15 approach each other, make the limiting plates 15 leave from below the slider 18, then move the slider 18 downward to separate it from the slot 17, then start the second motor 22 to make the second screw rod 23 rotate, make the moving plate 24 approach each other along the fixed frame 21, make the positioning blocks 25 approach each other and separate from the positioning slots 20, then disassemble the slide rail 19 and the slider 18, place the new slide rail 19 at a suitable position on the inner wall of the support frame 3, start the second motor 22 to make the second screw rod 23 rotate, make the moving plate 24 move away from each other along the fixed frame 21, make the positioning blocks 25 move away from each other, make the positioning blocks 25 completely insert into the positioning slots 20, make the moving plate 24 squeeze the slide rail 19 to complete the fixation of the slide rail 19, then move the slider 18 upward to make the slider 18 insert into the slot 17, start the first motor 7 to make the rotating shaft 8 rotate, make the first bevel gear 9 rotate, make the second bevel gear 10 rotate, make the first screw rod 11 rotate, make the moving blocks 13 move away from each other along the guide rods 14, make the limiting plates 15 move away from each other, make the limiting plates 15 move to below the slider 18 to limit the slider 18, and thus complete the fixation of the slider 18.
