Complex thin wall aluminum alloy stair die casting forming technology

Abstract

The invention provides a complex thin wall aluminum alloy stair die casting forming technology. Special software is adopted for conducting the mechanical performance analysis on a complex thin wall aluminum alloy stair structure, then special software is applied to conduct the die casting technology performance analysis on a complex thin wall aluminum alloy stair, the above two steps are repeatedly conducted, interactive iteration is conducted, and dual optimization is conducted. A method of interactive and iterative optimization of the mechanical performance analysis and the die casting technology performance analysis is adopted, and accordingly dual optimization for lightweight and casting forming performance of the complex thin wall aluminum alloy stair structure is achieved. The tread face wall thickness of the aluminum alloy stair obtained through the technology is smaller than or equal to 1.88 mm, the kicking face wall thickness of the aluminum alloy stair obtained through the technology is smaller than or equal to 1.81 mm, and the overall weight of the stair is smaller than or equal to 10.5 kg; after 500-3,000 N of static load, permanent deformation is avoided; and during supporting of the largest inclination angle (35 degrees) under the dynamic load of 500-3,000 N, permanent deformation is smaller than or equal to 2.1 mm, damage is avoided, and the technology level of a die casting product is domestically advanced.

Description

technical field [0001] The invention relates to the technical field of die-casting molding, in particular to a die-casting molding technology of complex thin-walled aluminum alloy steps. Background technique [0002] The die-casting industry is closely related to the development of escalators and is one of the important supports for the escalator industry. Today, people's requirements for escalators tend to be more and more reliable, low energy consumption, etc., and the steps are the most important and most critical components of escalators. Among them, the lightweight of aluminum alloy die-casting steps is the key to reducing emissions and consumption key technologies. Traditional aluminum alloy die-casting steps have disadvantages such as low toughness, low elongation, poor ability to allow deformation, complex manufacturing process, and high manufacturing cost, which easily cause quality defects. Therefore, improving the key technical indicators such as toughness, stre...
