It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a cutting device for the production of large flanges, the cutting device for the production of large flanges includes: a processing table 1, a through hole on the surface of the processing table 1, a lifting rod 2 inserted into the through hole, a positioning plate 3 on the upper surface of the lifting rod 2, a mounting frame 4 at the bottom of the lifting rod 2, an electric push rod 5 at the bottom of the processing table 1, a support frame 6 on the surface of the processing table 1, and a cutting device 7 inside the support frame 6;
[0022] Positioning plate 8, one end of positioning plate 8 is connected to second positioning plate 10 via hinge 9, and both positioning plate 8 and second positioning plate 10 are provided with protective frames 11 on their sides;
[0023] Before cutting, the workpiece to be cut is first placed on the processing table 1 and fixed. Then, the cutting device 7 can be lowered to cut the positioned workpiece. During cutting, the protective frame 11 set on the side of the cutting device 7 can be used to block the flying debris generated by cutting, thereby preventing the debris from flying in all directions and making it convenient for subsequent workers to collect and handle the debris.
[0024] Example 2: Based on Example 1, a lifting rod 2 is provided to facilitate the positioning of the workpiece to be cut. The lifting rod 2 can move up and down in the through hole opened on the surface of the processing table 1. The positioning plate 3 is fixedly connected to the upper surface of the lifting rod 2. The electric push rod 5 is fixedly connected to the bottom of the processing table 1. The mounting bracket 4 is fixedly connected to the lifting end of the electric push rod 5. The support bracket 6 is fixedly connected to the surface of the processing table 1. The cutting device 7 is an existing lifting cutting machine. The surface of the processing table 1 is provided with a cutting groove 18.
[0025] When in use, first place the workpiece on the surface of the processing table 1, then start the electric push rod 5 to move the lifting rod 2 down, so that the positioning plate 3 can press and fix the upper surface of the workpiece, and then it is convenient to use the cutting device 7 to cut the workpiece. The opening of the cutting groove 18 can avoid the problem of the cutting blade in the cutting device 7 colliding with the surface of the processing table 1 during cutting.
[0026] Example 3: Based on Example 2, a protective frame 11 is provided to prevent the flying of debris generated during cutting. The positioning plate 8 and the second positioning plate 10 can be rotated by the hinge 9.

Then, the protective frame 11 can be used to block the flying debris. When the cutting device 7 moves down to cut, the auxiliary frame 17 can increase the protection range of the protective frame 11. In addition, the lifting and lowering of the support rod 14 can prevent the auxiliary frame 17 from obstructing the downward movement of the cutting device 7. The setting of the limit spring 15 also makes it convenient for the auxiliary frame 17 to automatically reset after being pressed. The screw connection between the positioning screw tube 16 and the support rod 14 also makes it easy to remove the auxiliary frame 17.
