Combined technologies are of especially great interest to the automobile industry, first of all, to the operation of folding sheet metal. It is necessary to conduct exhaustive research of static-dynamic processes to ensure upgrading of quality of assemblies. In this connection development of new combined technologies of folding is an urgent problem. The proposed technology of folding combines static and dynamic loadings. In this case a pulsed magnetic field is used as a source of dynamic loading. Pulse-magnetic loading has such advantages as contactless micro- or millisecond action. This makes it possible to perform the operation of folding in a single stroke of the press (without stopping it). Moreover, it is possible to simplify considerably the stamping tooling, to raise productivity and quality of finished products.
