Description

technical field [0001] The invention belongs to the technical field of hydraulic machinery and instrument automation measurement, in particular to a heat medium bulging testing machine. Background technique [0002] In recent years, lightweight, energy saving, and green manufacturing have put forward higher requirements for the aerospace and automotive fields. Lightweight materials such as aluminum alloys, titanium alloys, magnesium alloys, aluminum-lithium alloys, and composite materials have been widely used, but these materials have poor plasticity at room temperature and are difficult to form using traditional techniques. Sheet metal hot medium forming technology combines the advantages of thermoforming and liquid filling forming, and is especially suitable for the forming of the above-mentioned light materials. The feature is that fluid pressure participates in sheet metal forming as an important process parameter, and the sheet metal forming limit is significantly imp...
