Description

technical field

[0001] The invention belongs to the technical field of sheet material progressive forming processing, and in particular relates to a sheet material electroplastic progressive forming device and a forming method thereof. Background technique

[0002] Electroplastic effect (electroplastic effect) refers to the material (including various metal materials, ceramic materials, superconducting materials, powder metallurgy products, etc.) under the action of moving electrons (current or electric field), the deformation resistance drops sharply and the plasticity improves significantly. The phenomenon is a result of the joint action of various physical effects including Joule heating effect, magnetic compression effect and pure electroplastic effect. The electroplastic effect was first discovered in 1963 by the former Soviet scholar Troitskii when he was doing research on surfactants, and then the former Soviet Union and American scholars conducted a lot of research. ...
