[0002] Scrap steel refers to the steel waste that does not become products in the production process of steel mills (such as trimmings, ends, etc.) and the steel materials in equipment and components that are scrapped after use. Scrap steel is steel in composition and can be recycled and reused.

[0003] Among them, after search, it was found that there was an application number CN202021294754.X, which disclosed a cutting device for scrap steel processing, including a fuselage, a base, a first telescopic cylinder, a slide rail, and a workbench. The device has the advantages of rotating the first hand wheel to make the first lead screw sleeve move freely in the horizontal direction without deviating from the direction under the cooperation of the first slider and the guide rail, thereby driving the second telescopic cylinder and the saw disc to move, so that the saw disc can move freely in the horizontal direction, thereby improving work efficiency and improving practicality.

[0004] However, after research, it was found that the saw disk of the device can only move horizontally, which makes the saw disk's moving path single and cannot move in any direction according to the cutting path. It is not flexible to use, and there is no structure to clean the rust and other impurities on the surface of the scrap steel before cutting. The rust and other impurities on the surface of the scrap steel will affect the cutting efficiency, making it inconvenient to load and unload the scrap steel, and it is not convenient to use. Therefore, a new device is provided to solve this problem. Utility Model Content
