Automobile Castings Dedicated Production Line To Ensure Production

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

Development of the integration of the bridge shell, to replace the welding bridge shell and with axle casing cast axle shell of the new products to achieve the integrated casting casting, make full use of the advantages of casting forming. At present, the main form of the common cast axle housing is to press the seamless steel pipe at both ends of the axle housing as the axle casing and fix the bridge shell assembly with the pin. To further improve the strength, stiffness and simplification of the bridge shell, FAW Group has developed an integrated bridge shell that directly casts the axle casing (part of the axle housing on both sides of the bridge shell) directly on the axle housing,Automobile Castings The bridge shell structure tends to be simple, and the axle shell rigidity is good, can be made of complex and ideal shape, wall thickness can change, can get the ideal stress distribution, its strength and stiffness are larger, Reliable work. As a result of the integration of the axle casing, the casting size is significantly increased, the casting length is 2 258 mm and its weight is more than 200 kg. In view of the characteristics of this integrated casting, enterprises set up a dedicated production line to ensure production.

The development trend of Automobile Castings integration is more obvious in the development of nonferrous alloy castings. In order to make full use of the casting process to achieve the characteristics of the production of complex structural castings, there have been integrated design of the door panels, seat skeleton, dashboard skeleton, front frame and firewall integrated design of high-pressure castings, the size is significantly larger than the current production Casting, the need for 4 000 ~ 5 000 t or even larger tonnage die-casting machine for production.

To ensure the strength and safety of the car under the premise of the car as much as possible to reduce the quality of the preparation, to achieve lightweight, thereby enhancing the vehicle's power, reduce fuel consumption and reduce exhaust pollution. The quality of the vehicle is reduced by 100 kg and the fuel consumption per 100 km can be reduced by 0.3 to 0.6 L. If the vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6% to 8%. With the needs of environmental protection and energy conservation, the weight of the car has become the world's automobile development trend, the weight of automotive castings has become one of the important direction of development of automotive castings.

For the overall safety factor of the castings,Automobile Castings the equal thickness design is one of the main design methods for automotive castings. However, the main drawback of the equal thickness design is that the structural performance can not be fully exploited and the weight of the casting is increased. Using CAE analysis, topology optimization and other means to optimize the design of parts, so that parts of the stress value of the 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 material the weight of. Taking into account the casting forming can achieve the formation of complex structural castings, you can achieve a variety of irregular shaped cross-section. Design, the use of CAE or topology optimization and other means, the stress analysis of parts. According to the distribution of the force, determine the shape of the parts and the specific local material thickness. Through the casting reinforcement, digging holes and thickening, can greatly reduce the weight of parts.

Commercial vehicle bearings to optimize the design before and after the casting shape comparison, showing the initial weight of castings 6.6 kg,Automobile Castings which is designed for a typical thick design. After a series of lightweight design methods such as reinforcement, digging and variable cross-section, the casting weight becomes 3.0 kg and the weight loss effect is more than 50%.

The use of aluminum and magnesium and other light alloy materials are the main weight loss measures of current automobile manufacturers. The density of aluminum is only 1/3 of steel, and has excellent corrosion resistance and ductility. The density of magnesium is smaller, only 2/3 of aluminum, excellent in high pressure casting conditions. Aluminum and magnesium specific strength (strength and quality ratio) are quite high, to reduce the weight, improve fuel efficiency plays a decisive role. US auto industry in the past two years to improve competitiveness, with its substantial use of aluminum and magnesium castings and integrated casting is closely related.
