[0018] 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.

[0019] Example: Figure 1-4 As shown, this utility model provides a stamping device for processing thin-walled metal tubes, including a worktable 1. The upper surface of the worktable 1 is fixedly connected to a placement seat 4 and a support 7. The placement seat 4 is located on one side of the support 7 and is used to initially place the thin-walled metal tube. The support 7 provides an installation position for a pneumatic slide table 5, etc. The upper surface of the worktable 1 is provided with a fixing mechanism 2 that works in conjunction with the placement seat 4. The fixing mechanism 2 facilitates the stable fixing of the thin-walled metal tube and prevents the thin-walled metal tube from moving during processing. The lower surface of the support 7 is fixedly connected to a pneumatic slide table 5, which enables the cylinder 8 to move precisely in the horizontal direction, providing a stable horizontal displacement path for the punch body 6 and ensuring that the punch body 6 can accurately align with the punching position of the metal tube.

[0020] A cylinder 8 is slidably connected to the lower surface of the pneumatic slide table 5. A mounting base 9 is fixedly connected to the output end of the cylinder 8. A punch body 6 is movably engaged in the inner cavity of the mounting base 9. The cylinder 8 facilitates the movement of the punch body 6 installed in the mounting base 9 to perform punching operations. An installation component 3 is provided between the punch body 6 and the mounting base 9. The installation component 3 facilitates the replacement of the punch body 6 and improves the convenience of using the stamping device.

[0021] The fixing mechanism 2 includes a mounting groove 21, which is located on one side of the workbench 1. A motor 22 is fixedly mounted on the inner wall of the mounting groove 21. A support base 23 for use with the motor 22 is fixedly connected to the inner wall of the mounting groove 21. The motor 22 is fixedly mounted on the upper surface of the support base 23, which provides a stable mounting position for the motor 22. The output end of the motor 22 passes through the mounting groove 21 and is fixedly connected to a bidirectional screw 27, which facilitates the output end of the motor 22 to drive the bidirectional screw 27 to rotate. A rectangular groove 24 is provided inside the workbench 1. The end of the bidirectional screw 27 facing away from the output end of the motor 22 is rotatably connected to the rectangular groove 24. A slider 28 is threaded on the outer surface of the bidirectional screw 27, which facilitates the rotation of the bidirectional screw 27 to drive the slider 28 to move.

[0022] The slider 28 is slidably disposed within the inner cavity of the rectangular groove 24. The slider 28 is threaded onto the opposite thread of the bidirectional screw 27, facilitating the rotation of the bidirectional screw 27 to drive the slider 28 to move in the same or opposite directions within the rectangular groove 24. A movable block 25 is fixedly connected to the upper surface of the slider 28, allowing the slider 28 to move and drive the movable block 25 to slide. A limiting groove 26 is formed on the inner wall of the rectangular groove 24 to cooperate with the movable block 25. The movable block 25 slides in conjunction with the limiting groove 26, which serves to limit the movement position of the movable block 25. The movable block 25 passes through the rectangular slot 24 and is fixedly connected to the movable plate 29, which facilitates the movement of the movable block 25 and drives the movable plate 29 to move. A fixed plate 201 is fixedly connected to one side of the movable plate 29, which facilitates the movement of the movable plate 29 and drives the fixed plate 201 to move. This allows the two fixed plates 201 to work together to fix the thin-walled metal tube more stably. The fixed plate 201 is a rubber anti-slip plate. The rubber material has a certain elasticity, which can buffer the pressure on the metal tube during fixation and avoid excessive compression and deformation of the thin-walled metal tube, thereby improving the processing effect of the stamping device.

[0023] The mounting assembly 3 includes symmetrically distributed grooves 32, which are symmetrically formed on the outer surface of the mounting base 9. The inner cavity of the groove 32 and one side of the punch body 6 are threadedly connected to a mounting bolt 35. The groove 32 provides an installation position for the mounting bolt 35. The inner cavity of the groove 32 is provided with a first positioning hole 33, and the outer surface of the punch body 6 is provided with a second positioning hole 31. The mounting bolt 35 is threadedly connected to the first positioning hole 33 and the second positioning hole 31. Through the threaded connection of the mounting bolt 35 to the first positioning hole 33 and the second positioning hole 31, the punch body 6 is accurately positioned and fixed on the mounting base 9.

[0024] The inner wall of the groove 32 is provided with an annular groove 36. An anti-loosening washer 34 is fixedly connected to the inner wall of the annular groove 36 to cooperate with the mounting bolt 35. After the mounting bolt 35 is tightened, the anti-loosening washer 34 can effectively prevent the mounting bolt 35 from loosening due to vibration or other reasons, effectively optimizing the installation structure of the punch body 6, making it more convenient and quick to replace the punch body 6.

[0025] Working principle: First, place the thin-walled metal tube to be processed on the placement seat 4.

[0026] Then, the motor 22 is started through the fixing mechanism 2. The output end of the motor 22 drives the bidirectional screw 27 to rotate. The rotation of the bidirectional screw 27 drives the two sliders 28 to move in the inner wall of the rectangular groove 24. The movement of the sliders 28 drives the moving block 25 to slide in the limiting groove 26, thereby driving the moving plate 29 and the fixing plate 201 fixed on one side of the moving plate 29 to move.

[0027] When the two fixed plates 201 move toward each other, they can stably clamp and fix the thin-walled metal tube on the placement seat 4. The rubber material can increase the friction to prevent the metal tube from moving during processing, and can also buffer the pressure on the metal tube to avoid its deformation, thereby ensuring the punching accuracy.

[0028] Then, by installing component 3, a suitable punch body 6 is selected, and the punch body 6 is snapped into a suitable position in the mounting base 9. The mounting bolt 35 is threadedly connected to the first positioning hole 33 and the second positioning hole 31 to achieve precise positioning and fixation of the punch body 6 on the mounting base 9.

[0029] Meanwhile, the anti-loosening washer 34 can prevent the mounting bolt 35 from loosening.

[0030] Next, the pneumatic slide 5 is activated, which drives the cylinder 8, which is slidably connected to its lower surface, to move in the horizontal direction to a predetermined position, so that the punch body 6 is aligned with the position where the metal tube needs to be punched.

[0031] After the positioning is fixed, start the cylinder 8. Its output end pushes the mounting base 9 and the punch body 6 to move towards the metal tube. The punch body 6 performs a punching operation on the metal tube.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
