<p>A machine for the automatic shaping of stator and rotor flat-wire coils to be used on rotating electric machines, including a main frame (10, 11) on which two specularly identical platforms, (204, 205) are mounted, one of which (205) is movable with respect to the other taken as a reference. Each of the two platforms is equipped with mounting and torsion grippers (310, 311) to seat the coil (600), these grippers being vertically mobile and rotatable in a vertical plane around a horizontal axis (79, 77) to obtain the desired orientation; two adjustable shaping elements (330, 331) mounted to be positioned with three freedom degrees on the associated supporting element (80, 40) of the respective horizontal axis (79, 77); a coil eyelet clamping device (227) that can move longitudinally and in a vertical plane; and a longitudinally mobile carriage (360) on which a thrusting element (365) is mounted. Furthermore the double pushing ends (366, 366a) of the thrusting element (365) can be independently positioned along a direction perpendicular to the plane defined by the longitudinal and vertical directions of the machine. The machine operation is controlled by a central computer with a video graphic display, governing a plurality of members that are in turn equipped with local microporcessors. The machine is able to shape all kinds of coils, of any difficult shape and of size widely varying may be, it can be programmed very quickly and in a very precise way for any new shape desired, variations and changes concerning the final shape being accomplished in real time, and it is loaded frontally through a safety photocell barrier.</p> |
