[0034] Specifically, the metal part to be processed is placed above the U-shaped support plate 3, and the position of the positioning plate 7 is adjusted according to its length. When the position is adjusted, the knob 11 is turned, and the movable bar 9 is threadedly connected to the threaded groove 10 above the movable bar 9, so that the movable bar 9 moves toward the bottom of the cylinder 8. At this time, the rotating bar 12 will push the arc-shaped rack 13 outward during the movement, so that it engages with the rack 6, thereby fixing the position of the positioning plate 7. Subsequently, the second bevel gear 22 can be driven to rotate by rotating the rotating column 23, and through its meshing relationship with the first bevel gear 21, the first bevel gear 21 drives the first threaded rod 20 to rotate, thereby driving the outer L-shaped movable plate 24 to move to the left side of the base 1. At the same time, the DC motor 25 moves together with the L-shaped movable plate 24, thereby processing the metal part.

[0035] Reference Figure 1 、 Figure 2 and Figure 6 The adjusting mechanism 2 includes a disc 201, which is fixedly connected to the output end of the DC motor 25. A second chute 202 is provided on the left side of the disc 201. The inner wall of the second chute 202 is fixedly connected to a second threaded rod 204. The front end of the second threaded rod 204 passes through the disc 201 and is rotatably connected to a fastening block 205.

A spring 209 is provided at the bottom of the implemented button 208, and the arc-shaped clamping plate 210 is engaged with the cutting knife 207.

[0036] Specifically, by rotating the fastening block 205 to the left side of the disc 201, the second threaded rod 204 will reduce the extrusion with the disc 201, thereby facilitating rotation. By rotating the fastening block 205, the second threaded rod 204 can be driven to rotate, so that the outer movable block 203 moves, thereby adjusting the position of the groove block 206 above the cylinder 201. By pressing the button 208, the arc-shaped clamping plate 210 can be driven to move, thereby releasing the engagement with the cutting knife 207, which can facilitate the quick replacement of different cutting knives 207.

[0037] Reference Figure 1 、 Figure 2 and Figure 5 The moving assembly includes a first threaded rod 20, which is rotatably connected to the inner wall of the square groove 19, and a first bevel gear 21 is fixedly connected to the right side of the outer wall of the first threaded rod 20. The outer side of the first bevel gear 21 is meshed with the second bevel gear 22, and the front end of the second bevel gear 22 is fixedly connected to a rotating column 23. The outer side of the first threaded rod 20 is threadedly connected to an L-shaped moving plate 24, and the top of the L-shaped moving plate 24 is fixedly connected to a DC motor 25; the rear side of the top of the U-shaped support plate 3 is rotatably connected to an arc baffle 26, and the front side of the outer wall of the arc baffle 26 is fixedly connected to a handle 27; the inner side of the U-shaped support plate 3 is fixedly connected to a guide plate 28, and the left side of the top of the base 1 is fixedly connected to a collecting plate 29;

[0038] Specifically, by starting the hydraulic rod 15, the V-shaped block 16 can be driven to move to the right side of the base 1. At this time, the clamping plate 17 will move relative to each other, thereby clamping the metal parts. The arc-shaped baffle 26 can prevent the debris generated during the processing from flying toward the operator. The handle 27 can be used to easily open the arc-shaped baffle 26. The guide plate 28 can guide the debris generated during the processing to the collection plate 29 for easy cleaning. The moving range of the clamping plate 17 can be limited by the recess 33. By rotating the rotating column 23, the second bevel gear 22 is driven to rotate, and its meshing relationship with the first bevel gear 21 is utilized to drive the first threaded rod 20 to rotate. This process will prompt the outer L-shaped movable plate 24 to move smoothly to the left side of the base 1, and at the same time, the DC motor 25 will also move synchronously with the L-shaped movable plate 24.

[0039] Reference Figure 1 、 Figure 2 and Figure 5 The top front side of the base 1 is fixedly connected to a controller 30, which is electrically connected to the hydraulic rod 15 and the DC motor 25 respectively; the outer side of the controller 30 is fixedly connected to a housing 31, and the outer side of the housing 31 is rotatably connected to a protective cover 32;

[0040] Specifically, the controller 30 can control the starting and operating power between the hydraulic rod 15 and the DC motor 25 respectively. The shell 31 can prevent the controller 30 from being damaged due to collision. The protective cover 32 can prevent dust and the like from entering the controller 30 and causing damage to the electronic components inside it.

[0041] Working principle: Before using the device, first, the metal part to be processed should be placed securely above the U-shaped support plate 3. Then, the position of the positioning plate 7 is accurately adjusted according to the length of the metal part. When the position is adjusted to an appropriate position, the knob 11 is rotated to cooperate with the thread of the thread groove 10 above the movable bar 9 to achieve smooth movement of the movable bar 9 to the bottom of the cylinder 8. During this process, the rotating bar 12 pushes the arc-shaped rack 13 outward until it is stably engaged with the rack 6, thereby ensuring that the position of the positioning plate 7 is firmly fixed. Then, by rotating the rotating column 23, the second bevel gear 22 is driven to rotate, and the meshing relationship between the second bevel gear 22 and the first bevel gear 21 is utilized to drive the first threaded rod 20 to rotate. This process will prompt the outer L-shaped movable plate 24 to move smoothly to the left side of the base 1. At the same time, the DC motor 25 will also move synchronously with the L-shaped movable plate 24, thereby achieving efficient processing of metal parts.

[0042] Through the adjustment mechanism 2, when the fastening block 205 is rotated to the left, the squeezing force of the second threaded rod 204 on the disc 201 will be reduced accordingly, making the rotation operation easier. Through this rotation action, the second threaded rod 204 can be driven to rotate synchronously, thereby prompting the outer movable block 203 to move, so as to achieve the purpose of adjusting the position of the groove block 206 above the cylinder 201. In addition, by pressing the button 208, the arc-shaped clamping plate 210 can be driven to move, thereby releasing its engagement with the cutting knife 207, so as to facilitate the rapid replacement of different cutting knives 207.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
