Description

Technical Field

[0001] The utility model relates to the technical field of vanadium-nitrogen alloy ball presses, and more specifically to an extrusion molding device of a vanadium-nitrogen alloy ball press. Background Art

[0002] Vanadium-nitrogen alloy is an important alloy material, the main components of which are vanadium and nitrogen. Vanadium-nitrogen alloy has the advantages of high hardness, high strength, wear resistance, and corrosion resistance, and is widely used in many fields. At present, vanadium-nitrogen alloy is mainly used in the steel metallurgical industry, and can be used to produce high-strength, high-hardness, and wear-resistant steel. In the production and processing of vanadium-nitrogen alloy, the nitride vanadium alloy does not have a fixed shape after preparation, so it needs to be extruded to facilitate subsequent transportation and processing.

[0003] After searching, the utility model patent with announcement number CN218693882U discloses a high-strength extrusion molding device for a vanadium-nitrogen alloy ball press, including a workbench, a protective box is vertically provided at the center position of the top of the workbench, a feeding funnel is vertically provided on the top of the protective box, a first rotating shaft and a second rotating shaft are inserted in the protective box for symmetrical rotation, both ends of the first rotating shaft and the second rotating shaft extend to the outside of the protective box, the first rotating shaft and the second rotating shaft are symmetrically sleeved on the outer walls of the inner position of the protective box, and a driving component for controlling the rotation of the forming rollers is provided on the surface of the workbench; the patent can quickly screen and discharge the vanadium-nitrogen alloy spheres after production and collection through the reciprocating structure set up, and can also screen and collect excess vanadium-nitrogen alloy residues for secondary utilization, effectively saving resources and improving resource utilization.

[0004] However, the above patent still has the following shortcomings: the cleaning brush roller is located below the middle of the two forming rollers, and the cleaning brush roller will affect the falling of the spherical vanadium-nitrogen alloy after the two forming rollers press the vanadium-nitrogen alloy into a sphere, and the forming materials above the two forming rollers move downward by their own gravity, which will cause the raw materials entering the forming holes on the side of the forming rollers to be missing, affecting the forming effect. For this reason, we propose an extrusion forming device for a vanadium-nitrogen alloy briquette machine. Utility Model Content
