Method for forming thin-wall metal component by controlling inflation position

Abstract

The invention belongs to the technical field of thin-wall metal component forming and manufacturing, and relates to a method for forming a thin-wall metal component by controlling an inflation position, which can solve the problems that the position of an inflation inlet is fixed, the inflation position cannot be changed, and the temperature field distribution of a plate is unreasonable due to inflation of high-pressure gas in the existing high-temperature air pressure bulging process. The defects of local thinning, cracking, uneven wall thickness distribution and the like occur in the forming process, and for thin-wall metal components with complex structures, flowing of materials cannot be reasonably regulated and controlled in the forming process, the materials cannot be evenly distributed, and the performance of the components is weakened are solved. According to the method, the inflation position is flexibly designed according to the structural characteristics of the complex thin-wall metal component, the purpose of regulating and controlling reasonable distribution of the plate temperature field is achieved, then the plastic deformation degree of different areas of the plate is regulated and controlled, and the problems of serious wall thickness reduction and serious material accumulation during local feature forming are solved; a complex thin-wall metal component can be subjected to multiple times of bulging, flowing of materials is reasonably regulated and controlled, material distribution is adjustable and controllable, and the performance of a bulging part is improved.

Description

technical field [0001] The invention belongs to the technical field of forming and manufacturing thin-walled metal components, and in particular relates to a method for forming thin-walled metal components by controlling the inflation position. Background technique [0002] With the development of the automotive industry and the aerospace industry, the application of thin-walled metal structural parts is becoming more and more extensive. This type of parts usually requires high precision, high performance and high reliability, which directly affects the service performance of the equipment. They are the key components of new energy vehicles and new generation airborne equipment. Such thin-walled metal components are often made of lightweight and high-performance materials such as aluminum alloys, magnesium alloys, and titanium alloys. Such materials have low plasticity and poor formability at room temperature, so they need to be formed at high temperatures, and their shape,...

Problems solved by technology

[0006] The purpose of the present invention is to provide a method for forming thin-walled metal components by controlling the inflated position, which can solve the problem that the position of the inflated port is fixed in the existing high-temperature pneumatic bulging process, and the inflated position cannot be changed. The temperature field distribution is unreasonable, and defects such as local thinning, cracking, and uneven wall thickness distribution occur during forming. For thin-walled metal components with complex structures, the flow of materials cannot be reasonably controlled during forming, and the materials cannot be evenly distributed, resulting in poor performance of components. problems such as weakening
