<p>03-A0-5173 ___ ._ _ Apparatus includes means that both advance wedge material stock and also substantially permanently form the stock material to precise dimensional tolerances; means by which the formed material is retained in the formed configuration thereof; wedge severing means; and means for loading severed wedges into a wedge magazine. The wedge magazine comprises the lower tooling of a coil injection machine and forms, in effect, an extension of tool gaps that accommodate winding coils in a coil injection machine. The magazine receiving the wedges may be a short term storage magazine which in turn feeds the wedges to a wedge magazine that forms the lower tooling of a coil injection machine. The multifunction machines that perform the multiple function of: making wedges for stator cores, inserting coils of winding turns into stator cores, and placing the wedges in at least selected slots of a stator core. The means for advancing wedge material stock and also substantially permanently forming the stock material includes a pair of pinch wheels or rollers that pinch the stock therebetween to feed wedge material. One of the wheels is driven through a clutch-brake system arranged so that it may be driven unidirectionally only from a reciprocating drive arm. The other wheel is supported so that it may be selectively urged toward the first wheel in order to pinch and feed wedge stock material. The wheels or rollers are contoured and dimensioned 50 that wedge material being rolled therebetween will be formed into a desired configuration. The forming of precisely controlled dimensional tolerances and dimensional stability, with the 03-A0-5173 result that the wedges lie squarely in stator core slots (when the wedges are inserted into such slots), and "wire over wedge" problems associated with skewed wedges in stator core slots are overcome.</p> |
