Description

technical field [0001] The invention relates to a metal plate warm forming device and method, in particular to a metal plate magnetic-temperature dual-temperature-controlled forming device and method based on a magnetically sensitive and phase-changeable soft material. Background technique [0002] Sheet metal forming has significant advantages such as high processing efficiency and high material utilization rate, and occupies an important position in the industrial field. In recent years, as resource and environmental issues have become increasingly acute, structural lightweight has become an important development direction, followed by the application of a large number of new metal materials. Compared with traditional metal materials, many new metal materials are difficult to form at room temperature. In order to improve their formability, warm forming processes are often required. Existing studies have shown that the performance of the force transmission medium itself ha...
