ROLL-FORMING PROCESS AND SYSTEM, IN PARTICULAR FOR PRODUCING A HIGH-PRECISION HOUSING FOR HIGH- PERFORMANCE ELECTRIC MOTORS, AND HOUSING PRODUCED THROUGH SUCH PROCESS

摘要

A roll-forming process is described, in particular for producing metal housings (1) for electric motors, comprising the steps of stamping a metal band to obtain at least one metal strip (2) to be worked and rolling such metal strip (2), such step of rolling comprising the steps of mechanically bending such metal strip (2) to make a cylindrical housing (1) and hydraulically calibrating such housing (1) around a cylindrical punch (3).
