Precise alloy casting for mechanical arm and casting method of precise alloy casting

Abstract

The invention provides a precise alloy casting for a mechanical arm and a casting method of the precise alloy casting, and relates to the technical field of precise alloy materials. The precise alloy casting comprises chemical elements including, by mass percent, 1.1%-1.6% of C, 1.8%-3.5% of Mn, 1.52%-2.83% of Al, 0.11%-0.2% of Cr, 0.08%-0.16% of Ni, 0.12%-0.19% of Co, 0.23%-0.37% of W, 0.22%-0.43% of Cu, 0.12%-0.43% of Nb, 0.12%-0.20% of Fe, smaller than or equal to 0.04% of Re, smaller than or equal to 0.04% of S, smaller than or equal to 0.04% of P and the balance Ti. According to the precise alloy casting, rare metal elements are adopted, many external cores are formed when the casting is cast, grains are refined or the crystal habit is changed, and the precise alloy casting is formed; and accordingly, the mechanical performance of the casting is improved, the surface smoothness of the casting is high, internal defects of the casting are few, components are pure, and performance is stable.

Problems solved by technology

[0004] At present, the mechanical arms used in the stamping industry are often adjusted left, right, up, down, or forward and backward on a plane. The operation of the mechanical arm will cause the wear of various parts of the mechanical arm, and the surface of the casting is severely worn. Therefore, the existing mechanical arm products have many technical limitations. Due to the insufficient precision of the mechanical arm components, it will affect its mechanical properties and wear resistance, reducing Service life of the arm
