Production process of ABS valve body material for cars

Abstract

The invention provides a production process of the automobile ABS valve body material, which includes the following steps: preparing raw materials, melting, refining and standing, filtering and casting, homogenizing, ingot processing, ingot heating, indirect extruding, on-line water quenching, stretch rolling, artificial aging and finished product inspecting. By adopting the optimized alloy component in combination with indirect extrusion technology and on-line heat treatment technology, particularly the indirect extrusion technology, the inventive production process achieves the high uniformity of material structure, head-and-tail measures and mechanical property, thereby solving the problems of 6061 alloy coarse grain zone and mechanical property, increasing the production yield index, reducing the energy consumption of unit product, obtaining the material of which the mechanical property, metallographic structure, dimensional precision and the surface quality reach the advanced level of foreign similar products, achieving the import substitution of the material and laying the foundation of automobile localization.

Description

technical field [0001] The invention belongs to the technical field of aluminum material processing, and in particular relates to a production process of an ABS valve body material for automobiles. Background technique [0002] With the requirements of energy saving and environmental protection, automobiles are developing towards modernization and light weight, and high oil prices have activated the rapid development of aluminum used in automobiles, and the amount of aluminum materials will increase year by year. The amount of aluminum used in automobiles in my country is far less than that in foreign countries, currently less than half of that in foreign countries. Many key aluminum materials need to be imported. Among them, high-quality and high-precision aluminum materials for ABS valve body materials for automobiles rely on imports from Germany. High-quality and high-precision aluminum materials for ABS valve body materials for automobiles are widely used in automobile o...

AI Technical Summary

Problems solved by technology

Since the optimal ratio of 6061 alloy components and the precise control of trace element components have not been optimized and adjusted, the structure and mechanical properties of the material cannot meet the requirements of aluminum for automotive ABS valve body materials; and from the extrusion process, Most manufacturers in my country use the forward extrusion process when producing aluminum materials. Due to the large friction between the ingot and the extrusion cylinder during forward extrusion, the metal flow is not uniform, which makes the metal deformation uneven, thereby increasing Due to the inhomogeneity of the structure, performance and size of the extruded product, it is difficult to ensure the uniformity of the mechanical properties of the head and tail of the material, and the uniformity of the dimensional accuracy of the head and tail, and the surface of the ingot undergoes intense shear deformation when the metal is deformed, making the After heat treatment, the product is easy to form coarse-grained rings, which cannot meet the requirements of aluminum materials for ABS valve body materials used in automobiles.

The Gansu Science and Technology Information Research Institute (Gansu Science and Technology Novelty Search and Consulting Center) concluded that: For the ABS valve body material used in automobiles, through the optimal control research of the alloy composition content, the reverse extrusion technology and the system process are adopted. Advanced process parameter optimization control technology to achieve the consistency of head and tail dimensions and mechanical properties of extruded products. There are no relevant literature reports at home and abroad.
