Abstract

The invention belongs to the field of metal material processing forming, and relates to an electromagnetic pulse based light alloy plate gas bulging forming device and forming method. The problems that an existing magnetic pulse forming process is only suitable for forming of high-conductivity materials, forming precision is low, and the universality of adopted flat plate coils is poor are solved. According to the device, the outer edge of a plate is fixedly arranged between a concave die and a supporting body, and a gas chamber is formed by the supporting body and the plate. The interior of the gas chamber, the interior of a first high-pressure gas storage unit and the interior of a second high-pressure gas storage unit are communicated pairwise. A gas pressure increase unit increases pressure of gas in the second high-pressure gas storage unit. A compression unit extrudes gas of the first high-pressure gas storage unit into the gas chamber under the action of an electromagnetic pulse generation unit. The method comprises the steps of heating the plate, performing the plate through the electromagnetic pulse generation unit and the compression unit and completing final forming of the plate through the gas pressure increase unit. The electromagnetic pulse based light alloy plate gas bulging forming device and forming method are used for complex forming of light alloy plates.

Description

technical field [0001] The invention relates to a metal plate forming device and a forming method, belonging to the field of metal material processing and forming. Background technique [0002] In recent years, with the increasingly prominent energy and environmental issues, light alloy materials represented by aluminum alloys, magnesium alloys and titanium alloys have become more and more widely used. Light alloy materials have long been inseparable from human life, production and social development. important material. [0003] The complex forming of light alloy sheets has always been a hot topic in the field of metal material processing and forming. At room temperature, the plasticity of the light alloy sheet is poor, and the light alloy sheet is prone to fracture during the complex forming process. Although the use of hot forming process can significantly improve the formability of light alloy sheets, the existing hot forming process has a long cycle and high cost, and...
