Superplastic forming process for automobile parts

Abstract

The invention relates to the technical field of automobile production, in particular to a superplastic forming process for automobile parts. The superplastic forming process comprises the following steps of step 1, selecting an aluminum alloy material of a corresponding model according to the requirements for the automobile parts; step 2, conducting blanking according to the size required by the forming process, and conducting surface quality inspection of the selected material; step 3, spraying a release agent on the two sides of the selected material; and step 4, preheating a mold, and afterthe mold is heated to a threshold value, putting the material into the mold for forming. By means of the novel superplastic forming process, the automobile parts machined by an aluminum plate have higher percent of pass and more complex curved surface shapes, scrap of the aluminum plate and the rejection rate of the parts can be greatly reduced in the forming process, and meanwhile, the materialutilization rate is greatly increased.

Description

technical field [0001] The invention relates to the technical field of automobile production, in particular to a superplastic forming process for automobile parts. Background technique [0002] There are many types of auto parts. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts has become larger and larger. In recent years, auto parts manufacturing plants are also developing rapidly. However, in the prior art, the sheet metal processing of the automobile profile is not in place, and the aluminum alloy is a lightweight general-purpose material as parts such as automobile cover parts or structural parts. However, in the process of aluminum plate processing and forming, the single stamping method through the mold is likely to cause a large amount of material scrapping, and the investment in equipment and tooling is large, resulting in an increase in production costs. In view of this, we propose a superplastic ...

Problems solved by technology

However, in the prior art, the sheet metal processing of the car shape is not in place, and aluminum alloy is a light-weight general-purpose material for parts such as car panels or structural parts.

However, in the process of aluminum plate processing and forming, it is easy to cause the scrapping of a large amount of materials by simply stamping through the mold, and the investment in equipment and tooling is large, resulting in an increase in production costs.
