Wear-resisting and corrosion-resisting alloy casting for mechanical arm and preparation method thereof

Abstract

The invention provides a wear-resisting and corrosion-resisting alloy casting for a mechanical arm and a preparation method thereof. The wear-resisting and corrosion-resisting alloy casting is prepared from the following components in percentage by mass: 0.4 percent to 0.6 percent of C, 1.2 percent to 1.4 percent of Si, 0.9 percent to 1.2 percent of Mn, 0.3 percent to 0.35 percent of W, 18 percent to 20 percent of Cr, 3.5 percent to 5 percent of Ni, 0.025 percent to 0.03 percent of B, 0.3 percent to 0.5 percent of Mg, 0 to 1.5 percent of Cu, 0 to 0.4 percent of Zn, 0.05 percent to 0.2 percent of rare earth oxide, 0.005 percent to 0.01 percent of N, less than or equal to 0.02 percent of P, less than or equal to 0.02 percent of S and the balance of Fe; the wear-resisting and corrosion-resisting alloy casting is prepared through the steps of hot melting, oxygen removing and degassing, inoculating, hot rolling, quenching, annealing and the like; the prepared alloy casting has excellent wear-resisting and corrosion-resisting performances and high strength and high rigidity; the anti-oxidization performance and the anti-deformation performance are also remarkably improved and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical casting, in particular to a wear-resistant and corrosion-resistant alloy casting for a manipulator and a preparation method thereof. Background technique [0002] The manipulator is composed of an executive mechanism, a drive mechanism and an electrical control system, etc. It can automatically complete several prescribed actions according to a pre-selected program, and realize the automatic gripping and transportation of objects. In stamping production, it is not only used to complete the loading and unloading work on one press to realize single-machine automation, but also can be used on an assembly line composed of several presses to realize automatic transfer of workpieces between each press, forming an automatic Stamping production line. Since the manipulator can easily change the working procedure, it is more important for the realization of production automation in the stamping producti...

Problems solved by technology

For example, some existing manipulators need to work in a high-humidity environment, and even need to grab objects from the liquid for transfer. As a steel body, the corrosion and rust on its surface after being contaminated with chemical reagents or liquids greatly affect the service life. and efficiency, although the surface will be sprayed with a protective coating, it is also necessary to improve the wear and corrosion resistance of the manipulator itself
