Problems solved by technology

[0003] The currently used robotic arms are often adjusted left and right, up and down, or forward and backward on a plane. When the shapes of the products to be produced and processed are diversified and multi-directional adjustments are required, long-term operation will cause the various parts of the robotic arm to wear, especially serious surface wear, so the existing mechanical arm products have many technical limitations, and the service life is not long

Abstract

The invention discloses a wear-resisting casting for a mechanical arm and a preparation method thereof. The casting comprises, by mass, 0.8-1.05% of C, 5.1-7.2% of Mn, 0.8-1.2% of Si, 0.3-0.5% of Cr, 1.2-1.5% of V, 1.2-1.4% of Ti, 0.25-0.63% of Zr, 0.2-0.3% of Ce, 0.16-0.34% of Hf, and the balance Fe and inevitable impurities. By reasonably regulating the ratio of all the elements to enable the elements to generate the synergistic effect, the comprehensive mechanical performance of the mechanical arm is remarkably improved, so that the wear-resisting casting has high strength, high toughness and high wear resistance. After long-time operating, the surface of the mechanical arm is free of peeling and is resistant to wear.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a method for preparing a wear-resistant casting for a mechanical arm. Background technique [0002] With the development of industrialization and informatization, people's requirements for industrialized production are getting higher and higher, and the requirements for operation accuracy are also higher. Therefore, when processing and producing some industrial precision devices, some mechanical arms are often used for operation, which can not only reduce the work intensity, but also improve the precision requirements for production requirements. The robotic arm can accept instructions and precisely locate a certain point in three-dimensional or two-dimensional space for operation. The mechanical arm generally has three movements: telescopic, rotating and lifting, wherein the rotational movement is completed by the cooperation of the mechanical arm and the corresponding mechanical...
