Description

Technical Field

[0001] The utility model relates to the technical field of steel billet processing, in particular to a cutting device for steel billet processing. Background Art

[0002] At present, flame cutting machines are usually used in the process of cutting steel billets. During use, the existing flame cutting machines melt the steel billets through a high-temperature flame cutting gun. Under the action of the impact force, the molten base material will splash everywhere. Although a cooling water tank is usually provided at the bottom of the steel billet for protection, there is no protection above the steel billet. Therefore, the splashed liquid base material will quickly adhere to the top of the steel billet, resulting in excessive debris attached to the surface of the steel billet, affecting the product quality. At the same time, a large amount of smoke and dust exhaust gas will be generated during the cutting process. Since there is no processing equipment, the smoke and dust exhaust gas will spread everywhere, causing harm to the health of the operator. Utility Model Content

[0012] 1. The utility model provides a collection protection component. On the one hand, the flame cutting gun is surrounded by cutting points, so that during the cutting process, the sparks splashing above the steel billet are limited to a range, and the cooling water in the splash-proof bottom plate is used to cool and collect the slag, thereby preventing the slag from adhering to the steel billet. On the other hand, the generated smoke and dust waste can be collected and purified, thereby preventing the smoke and dust waste gas from spreading, endangering the operator and polluting the environment.

[0013] 2. The utility model fixes the splash-proof bottom plate by setting a fixing component through a snap-on method, which is conducive to the rapid disassembly of the splash-proof bottom plate at a later time and the centralized treatment of the collected debris and waste water. At the same time, by setting a flat-top conical block, it is conducive to multi-point support of the steel billet, and the flame damage of the gun head to the support plate is reduced by reducing the contact area between the gun head and the steel billet. In addition, the inclined surface on the flat-top conical block can block and guide the sputtering sparks. BRIEF DESCRIPTION OF THE DRAWINGS
