AUTOMATIC HAIRPIN CONDUCTOR FORMING MACHINE FOR THE PROCESSING OF DC MOTOR ARMATURES USING ROUND COPPER WIRE (ACM106)

The ACM106 hairpin forming machine is designed especially for single turn conductors for DC motor armatures and cannot be used for other case of application. Raw material is bare or enameled round copper wire, provided on spools of appropriate size. The wire feeding of the machine is done by a motorized device, dereeling with speed, synchronized with the machine working rate. The machine performes consecutively the operations of wire straightening, feeding the exact developped lenght of wire, "U"-bending and cutting-off with end pinching and twisting of the legs at the needed angle. Additional attachments are provided for stripping of the wire varnish at the hairpin ends when enameled wire is used. All machine units are mounted on the alluminum longitudinal machine frame, thus giving the possiblity to readjust them according to the specific developed wire length. Exact position of the main units can be read on the machine millimetric scales in order to record the specific hairpin parameters and use them for future easier readjustment.

Approximate capacity: 2500 conductors/hr.
