[0026] In order to solve the problem that when the cutting device for metal crafts is used to cut metal crafts, the cutting blade is not shielded and protected, which is extremely dangerous and reduces the safety of the device. Figures 1 to 4 The structure of the device body is a processing table 1 and a fixed plate 5. Both ends of the top of the fixed plate 5 are slidably connected to the limit rod 6 through the through grooves. The fixed plate 5 is set to fix the moving path of the limit rod 6. The top and bottom ends of the limit rod 6 are fixedly connected to the limit block 7 and the movable plate 9 respectively. The set limit rod 6 provides a connecting function to realize the synchronous movement of the limit block 7 and the movable plate 9. At the same time, the set limit block 7 is located at the top of the fixed plate 5, which is convenient for preventing the limit rod 6 from falling off through the set limit block 7, thereby improving the structural stability of the device parts. The side of the movable plate 9 is slidably connected with a shielding cover 10, and the set shielding cover 10 provides a shielding and protection function, so that the movable plate 9 moves along the inner wall of the shielding cover 10, and the moving path of the movable plate 9 is fixed.

[0027] Both ends of the top of the shielding cover 10 are slidably connected to the limit rod 6 through the opened through grooves, and a booster spring 8 is sleeved on the side of the limit rod 6. The top and bottom ends of the booster spring 8 are fixedly connected to the fixed plate 5 and the shielding cover 10 respectively. The set booster spring 8 provides an elastic thrust to prevent the shielding cover 10 from shaking when providing shielding protection, thereby improving the shielding and protection effect of the shielding cover 10 and improving the safety of the device. The bottom end of the movable plate 9 is fixedly connected to a U-shaped inverted limit plate 11, and a rotating motor 12 is installed on the side of the limit plate 11. The output shaft of the rotating motor 12 is fixedly connected to a cutting knife 13 for cutting metal crafts. The set rotating motor 12 provides power to rotate the output shaft of the rotating motor 12 to drive the cutting knife 13 to perform rotational cutting on the metal crafts.

[0028] A U-shaped inverted support plate 2 is fixedly connected to the top of the processing table 1, and the support plate 2 is provided to provide support. A linear motor 3 is installed at the bottom of the support plate 2. The moving part of the linear motor 3 is fixedly connected to an electric telescopic rod 4. The linear motor 3 and the electric telescopic rod 4 provide power, which facilitates the lateral and longitudinal movement of the cutting knife 13 during the transmission process, thereby improving the cutting flexibility of the cutting device for metal crafts. The moving end of the electric telescopic rod 4 is fixedly connected to the fixed plate 5, and a telescopic outer rod 14 is fixedly connected to the side of the limit plate 11. A moving block 15 is slidably connected to the side of the telescopic outer rod 14 through an inner cavity. The telescopic outer rod 14 fixes the moving path of the moving block 15. An extension rod 16 and a connecting rod 18 are fixedly connected to the two sides of the moving block 15, respectively. The extension rod 16 and the connecting rod 18 extend in opposite directions in the inner cavity of the telescopic outer rod 14, and a limiting spring 19 is sleeved on the side of the connecting rod 18.

[0029] The two end surfaces of the limit spring 19 are fixedly connected to the moving block 15 and the telescopic outer rod 14 respectively, and the end surface of the extension rod 16 passes through the limit plate 11. The set limit spring 19 provides elastic thrust to make the moving block 15 move toward one side of the extension rod 16. The end of the extension rod 16 away from the moving block 15 is fixedly connected with a grinding block 17. The side of the grinding block 17 overlaps with the cutting knife 13, and the extension rod 16 provides an extended support function. The set grinding block 17 grinds the surface of the cutting knife 13 to prevent the cutting knife 13 from being used for a long time, resulting in the bluntness of the blade, thereby improving its cutting effect and cutting efficiency.

Their working principles, sizes, and models are irrelevant to the functions of the present application, so they will not be described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] How it works

[0032] When using the cutting device for processing metal crafts, the user places the metal craft to be cut on the top of the processing table 1, starts the electric telescopic rod 4, and starts the rotating motor 12 at the same time. The moving end of the electric telescopic rod 4 drives the cutting knife 13 to move to the specified position during the transmission process. At the same time, the output shaft of the rotating motor 12 rotates to drive the cutting knife 13 to perform rotary cutting on the metal craft. The shielding cover 10 is provided to provide shielding and protection to prevent safety accidents caused by the cutting knife 13 during the rotation process, thereby improving the safety of the device. At the same time, it is convenient to move the shielding cover 10 along the path of the limiting rod 6, so that the shielding cover 10 can be moved longitudinally to prevent it from affecting the cutting process of the metal craft. The limiting block 7 is provided to prevent the limiting rod 6 from falling off, and the movable plate 9 is provided to prevent the shielding cover 10 from falling off, thereby improving the structural stability of the device parts.

[0033] The booster spring 8 is provided to provide an elastic thrust to prevent the shielding cover 10 from shaking when providing shielding protection, thereby further improving the safety of the device. The grinding block 17 is provided to contact the cutting knife 13 to grind the cutting knife 13 to prevent the cutting knife 13 from being blunted due to long-term use, thereby reducing the cutting efficiency and cutting effect of the metal crafts. Under the elastic thrust of the limit spring 19, the moving block 15 moves along the inner cavity of the telescopic outer rod 14. Through the connecting function of the extension rod 16, it is convenient to push the grinding block 17 to be close to the cutting knife 13, thereby improving the grinding effect of the grinding block 17 on the cutting knife 13, and preventing the grinding block 17 from being in contact with the cutting knife 13 for a long time, which may easily cause the grinding block 17 to continuously grind the cutting knife 13 and cause damage to the cutting knife 13. The electric telescopic rod 21 is started, and the movable block 20 is driven to move by the moving end of the electric telescopic rod 21. During the transmission process, the overlap between the grinding block 17 and the cutting knife 13 is released, thereby improving the convenience of using the device.
