METHOD FOR THE MANUFACTURE OF BUNDLES OF METAL SHEETS OF ANNULAR SHAPE |
摘要 |
The method makes it possible to form a stator of an electric motor by means of a multiple-slide press (21, 22, 23). The starting point is a bundle consisting of rectilinear segments of sheets obtained by stamping and welded. The stator is formed by means of four successive operations carried out by four groups of slides of a multiple-slide press and corresponding dies. The cylinder formed is subsequently welded along its joining generatrix and is calibrated in a hydraulic press. |
