| 摘要 |
The present invention provides increased uniformity in the forming of coils wound onto a dynam-electric machine component core by providing an apparatus having a greater number of forming pushers in the same machine core space. The present invention adopts a space saving mechanism for radially driving and retracting the pushers. Two series of pushers are alternately arranged around a central axis. The first series of pushers is capable of being driven radially outwardly and being retracted radially inwardly by the actuation mechanism, while the second series of pushers is only capable of being driven radially outwardly by that mechanism. The first and second series of pushers are provided with overlapping protrusions and recesses, respectively, which enable the radially inward retraction of the first series of pushers to provide the same radially inward retraction for the second series of pushers. <IMAGE> |
