Description
Technical Field
The utility model relates to the technical field of new energy automobiles, in particular to an integrated front engine room for high-pressure vacuum casting of an automobile aluminum alloy.
Background
The automobile industry has undergone centuries of development to form a complete set of process systems-stamping, welding, coating and final assembly. The process system can provide a consumer with a high quality product. However, with the vigorous development of the internet and the upgrade of the consumption mode, the demands of users have gradually developed toward the direction of personalization and customization, and the automobile industry has also gradually shifted from mass production to small-scale personalization. Under the background, the traditional 4-step process is gradually becoming the bottleneck of industrial transformation and upgrading, and the integrated die casting process is gradually appearing in the field of vision of people.
The integrated die casting process has the following advantages:
first, lighten the whole car quality. The weight of the automobile body is about 20 percent of the weight of the whole automobile, and the weight reducing pressure is huge. At present, steel is a main part of a car body, while aluminum has the density of only 1/3 of that of steel, and weight reduction is expected to be obvious. Although steel is continuously upgraded and new steel types such as hot formed steel, third generation steel, 2GPa steel, low density steel and the like are appeared, the low density of aluminum is still quite competitive in front of the light weight requirement. Although the weight reduction effect of the current integrated die casting is not obvious, with the deep understanding of the die casting process, the continuous investment of development of new heat treatment-free materials is believed to greatly improve the application ratio of aluminum in the future.
Secondly, the development period of the whole vehicle is shortened. At present, the whole car is developed for about 2.5 years, and the market demands are changed day by day. How to shorten the development period quickly, the quick response market demand is a pain spot which is needed to be solved by the current host factories. The vehicle body structure has 850 parts and 230 assemblies, and the development is very time-consuming and labor-consuming. And the integrated die casting can integrate nearly hundred parts, so that the matched design time among the parts is greatly reduced. In addition, in the production and manufacturing process, the number of parts is reduced, so that the one-time yield of the product is improved, and the time for product trial production is greatly shortened.
Third, the investment of the whole vehicle factory is reduced. The traditional manufacturing process of the train enterprise is 4, consists of more than 200 stations, and calculates the investment requirement of a train body industrial chain at the position of a supplier. In the past, the market has low cycle requirements on product demand iteration, and investment of one vehicle type can realize profit for 5 years or even 10 years. Today it is possible that products are at risk of being eliminated without having been marketed. Through statistics, if the whole white car body adopts integral die casting, the workshop investment is saved by 16 hundred million, the occupied area of a factory is reduced by 30 percent, and the material utilization rate and the material recycling rate of the die casting full-aluminum car body can reach more than 95 percent, which are all advantages brought by integral die casting.
