Robot big cover plate and preparation process thereof

Abstract

The invention discloses a robot big cover plate and a preparation process thereof, and belongs to the technical field of a metal material. The big cover plate is prepared from the following raw material ingredients in percentage: 0.4 to 0.8 percent of Fe, 0.5 to 0.7 percent of Si, 0.02 to 0.04 percent of Ti, 0.05 to 0.09 percent of Mg, 0.01 to 0.03 percent of Be and the balance of Al and impurities. The Be in the raw materials is an excellent metal additive, has low density and has the intensity being 4 times of that of steel. The light weight and high intensity of the Be are used, so that thealuminum alloy has good physical performance; the mechanical performance of the aluminum alloy is enhanced; meanwhile, the oxygen affinity of the Be is used for reducing impurity oxygen in the aluminum alloy. The chemical properties of the Ti per se is stable; the embrittlement increase risk of the Fe on the alloy is eliminated; meanwhile, the preferential solidification characteristics of the Feare utilized so that a solidification core is formed; the mechanical property of the aluminum alloy is enhanced. Meanwhile, crystal grains are refined through the progressive normalizing processing and the uniform annealing process; the ingredient aliquation in the alloy can be eliminated. In addition, a nanometer stage carbon film is formed on the surface of the alloy; the intensity is high; theanti-corrosion performance of the aluminum alloy is greatly enhanced.

Description

technical field [0001] The invention relates to a large robot cover plate and a preparation process thereof, belonging to the field of metal materials. Background technique [0002] In order to liberate manpower, increase productivity, and improve work efficiency, robots have emerged as the times require. Robots in different industries may have different shapes, but the core is often the high-speed operation of the internal computer, and the external material that carries its internal structure is equally important. Aluminum alloy is widely used for its high strength, low density, and good corrosion resistance. Production with robots. [0003] Aluminum alloy refers to an alloy system based on aluminum, adding a certain amount of magnesium, silicon, molybdenum, chromium, manganese and other elements and controlling the content of impurity elements. Aluminum alloy has high strength, high hardness, light weight and good ductility, especially suitable for structural materials,...

AI Technical Summary

Problems solved by technology

General alloy materials and processing methods can be used in common environments, but in-depth research is still needed to improve the performance of aluminum alloys (such as strength and hardness)

[0005] In view of the shortcomings of traditional aluminum alloys such as many cracks and poor elongation, Publication No. 106048379A discloses a method to improve the toughness and elongation of the product by adding rare earth, strontium and other elements into the aluminum alloy.

However, only improving the toughness, elongation and other properties of aluminum alloys cannot make aluminum alloys cope with complex environments.
