Workpiece forming system with deformable die - uses magnetic field or shock wave for shaping workpiece against deformable die

摘要

The die forming system uses a magnetic field or shock wave. The workpiece is formed between the magnetic field or shock wave and a deformable support. This system includes forming methods using electromagnetic and electrohydraulic processes and also explosive effects. There is a deformable die which is manipulated into the same shape as the desired workpiece profile. Before the forming process the die body is laterally contracted in order to achieve deformation for a certain profile. The die body can be extended in at least one direction at right angles to the working surface in order to facilitate retraction for release. The die body is bent for removal.
