[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a CNC shearing machine for sheet metal processing, including a workbench 1, the workbench 1 is fixedly connected with a motor 2 inside, the output end of the motor 2 is fixedly connected with a worm 3, the workbench 1 is rotatably connected with a rotating disk 5 inside, the outer wall of the rotating disk 5 is fixedly connected with a worm gear 4, the worm 3 is meshed with the worm gear 4, the rotating disk 5 is internally slidably connected with a limiting wheel 6, the limiting wheel 6 is rotatably connected to the inside of the workbench 1, the rotating disk 5 is internally slidably connected with a clamping block 7, the clamping block 7 is internally slidably connected with a handle 8, the outer wall of the handle 8 is sleeved with a spring 9, one end of the spring 9 is fixedly connected to the inside of the clamping block 7, and the other end of the spring 9 is provided with a pressing component, the pressing component is used to press down the sheet metal, the pressing component includes a pressing plate 10, the upper surface of the pressing plate 10 is fixedly connected to the other end of the spring 9, the outer wall of the pressing plate 10 is fixedly connected with a guide rod 11, and the outer wall of the guide rod 11 is slidably connected to the inside of the clamping block 7;

[0025] Specifically, the output end of motor 12 first drives the worm 3 to rotate. As the worm 3 rotates, the worm wheel 4 matched with it also starts to rotate, thereby driving the start of the rotating disk 5. To ensure that the rotating disk 5 can rotate stably and accurately, the limit wheel 6 plays a guiding and positioning role. As the rotating disk 5 continues to rotate, the clamping block 7 slides in the arc-shaped slideway inside the rotating disk 5, thereby driving the clamping blocks 7 on both sides to approach each other, thereby clamping the sheet metal material. When the clamping block 7 is tightly fitted to the sheet metal, the inclined surface of the pressure plate 10 first contacts the sheet metal. Next, the sheet metal is guided by the inclined edge of the pressure plate 10 and slides to the bottom of the pressure plate 10 along the direction of the guide rod 11. In this process, the sheet metal will exert a certain pressure on the spring 19 to cause it to contract. The contraction of the spring 19 further pushes the pressure plate 10 to fit more closely on the workpiece, thereby achieving precise positioning of the sheet metal.

[0026] Reference Figure 1 and Figure 4 The upper surface of the workbench 1 is fixedly connected to a support frame 12, a motor 2 13 is fixedly connected inside the support frame 12, a cam 14 is fixedly connected to the output end of the motor 2 13, a transmission belt 15 is arranged on the outer wall of the cam 14, the outer wall of the transmission belt 15 is arranged inside the support frame 12, a sliding plate 16 is fixedly connected to the outer wall of the transmission belt 15, a slider 18 is fixedly connected to the outer wall of the sliding plate 16, a guide rail 17 is slidably connected inside the slider 18, the outer wall of the guide rail 17 is fixedly connected to the inside of the support frame 12, a slide plate 19 is fixedly connected to the outer wall of the sliding plate 16, a slide groove 20 is provided inside the support frame 12, the outer wall of the slide plate 19 is slidably connected to the inside of the slide groove 20, and a motor 3 21 is fixedly connected to the inside of the sliding plate 16, and a cutting plate 22 is fixedly connected to the output end of the motor 3 21;

[0027] Specifically, motor three 21 is started first, and the output drives the cutting plate 22 to perform precise cutting operations on the sheet metal. At the same time, motor two 13 also starts working, driving the cam wheel 14 to rotate. The rotation of the cam wheel 14 further drives the transmission belt 15 to move smoothly inside the support frame 12. The movement of the transmission belt 15 then drives the sliding plate 16 and the cutting plate 22 fixed thereon to move in parallel, which not only ensures the stability of the cutting plate 22 during the cutting process, but also greatly improves the cutting accuracy and efficiency. During the movement of the sliding plate 16, the slider 18 and the slide plate 19 thereon will slide on the guide rail 17 and the support frame 12, which not only ensures the smooth movement of the sliding plate 16, but also ensures the positioning accuracy of the cutting plate 22. Through the sliding of the slider 18 and the slide plate 19 on the guide rail 17, precise positioning and stable cutting of the sheet metal are achieved.

[0028] Working principle: When the CNC shearing machine for sheet metal processing is needed, the motor 2 drives the worm 3 to rotate, and the worm wheel 4 rotates accordingly, driving the rotating disk 5 to rotate. The limit wheel 6 ensures the stable rotation of the rotating disk 5. The clamping block 7 slides inside the rotating disk 5 to clamp the sheet metal material. The inclined surface of the pressing plate 10 contacts the sheet metal, guiding the sheet metal to slide under the pressing plate 10. The sheet metal applies pressure to the spring 9 to shrink it, so that the pressing plate 10 fits the workpiece more closely, realizing the precise positioning of the sheet metal.

[0029] In addition, the driving motor three 21 drives the cutting plate 22 to cut the sheet metal, and then the driving motor two 13 drives the concave wheel 14 to rotate, thereby driving the transmission belt 15 to move inside the support frame 12, thereby driving the sliding plate 16 and the cutting plate 22 to move in parallel. In this process, the movement of the sliding plate 16 will drive the slider 18 and the slide plate 19 to slide on the guide rail 17 and the support frame 12 to achieve positioning, thereby stably cutting the sheet metal.
