Automobile Castings Advanced Production Technology, Product Quality, And High Production Efficiency

Automobile Castings is one of the oldest metal forming methods. About 15% to 20% of automotive parts are Automobile Castingss produced by different Automobile Castings methods. These Automobile Castingss are mainly key components of power system and important structural components. At present, Europe and the United States automobile industry developed countries, automobile Automobile Castings production technology is advanced, product quality is good, high production efficiency, environmental pollution. Automobile Castings raw and auxiliary materials have been formed serialization and standardization, the entire production process has been achieved mechanization, automation and intelligence. These countries generally use digital technology to improve the level of Automobile Castings process design, Automobile Castings scrap rate of about 2% to 5%, and has established a multinational service system and network technology support. In contrast, although China's automobile Automobile Castingss larger output, but most of them are added value and low technical content, the structure is relatively simple black Automobile Castingss, and the gap between foreign level. This article mainly discusses the development direction of automobile Automobile Castings and automobile technology from the development demand of automobile energy saving and environmental protection. The development direction of automobile Automobile Castingss

With the automotive energy saving and reduce the cost of production requirements continue to increase, make full use of the advantages of Automobile Castings, the original stamping, welding, forging and Automobile Castings forming several parts, through reasonable design and structural optimization, to achieve integrated parts Automobile Castings Forming, can effectively reduce the weight of parts and reduce unnecessary processing technology, in order to achieve the weight of parts and high performance.

Due to the overall safety factor of Automobile Castingss, equal thickness design is one of the main design methods of automobile Automobile Castings. However, the main drawback of the isometric design is that the structural performance can not be fully exploited and the weight of the Automobile Castings is increased. Using CAE analysis, topology optimization and other means to optimize the design of parts, so that parts of the stress value of various parts close to the various parts of the wall thickness is inconsistent, small parts of the thinner material thickness or not to reduce the parts the weight of. Taking into account the Automobile Castings forming can achieve the formation of complex structure Automobile Castingss, can achieve a variety of irregular shaped cross-section. Design, the use of CAE or topology optimization and other means of stress analysis of parts. According to the distribution of forces, determine the shape of the parts and the specific local material thickness. Through the Automobile Castings reinforcement, digging holes and thickening, can greatly reduce the weight of parts.

 Improve the performance of the material, so that the weight of the unit can withstand higher loads, is to effectively reduce the weight of Automobile Castings one of the methods. Stent-type Automobile Castingss account for a significant proportion of Automobile Castingss, and the development of Automobile Castingss has also become one of the focuses. Through the heat treatment and other measures to make the material microstructure changes, thereby enhancing the strength of parts, stiffness or toughness, can effectively reduce the weight of parts.

       Isotonic quenched ductile iron, not only the strength of steel than ordinary steel has improved, and the density is lower than the steel, the density of 7.1 g / cm3, while the cast steel density of 7.8 g / cm3, is widely recommended in recent years, the material The The use of isothermal quenching ductile iron, in the same size of Automobile Castingss under the conditions of light, 10% lighter than steel. Dongfeng Motor Company in a certain type of commercial vehicles carried out by the use of isothermal quenching ductile iron instead of cast steel light weight verification work, and for the isothermal quenching ductile iron pieces of high strength characteristics of the 14 suspension parts into the expert forum line to redesign. Table 1 for the use of isothermal quenching ductile iron material after the replacement of the lightweight effect, the total weight reduction of nearly 40%, the effect is significant. It should be noted that the light weight effect in Table 1 is not only the material substitution, but also the contribution of the lightweight design. In general, material replacement for automotive Automobile Castingss is often accompanied by lightweight design of parts.
